Unit 2 Colours 单元话题阅读理解练习 Unit 2 Colours 单元话题：颜色 本资料共10篇专题训练，从上到下依次按照难度分为基础语篇巩固练和重难语篇提升练 基础语篇巩固练 There are many colours in nature. But do you think that a colour has weight? I think you’ll say “no”. But I’m afraid you are wrong. If you don’t believe it, you may do a small experiment. First, put two objects with the same weight into two boxes. Then cover the boxes. Third, wrap one box with a red piece of paper, the other one with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier. Why do you think so? A scientist found that different colours have different weights in man’s mind. That is to say, every colour has its own weight in our mind. The scientist told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientist say so? That is because every colour stands for a kind of light with a certain wavelength (波长). It reaches our brain through sense organs. According to this discovery, scientists say that people accept the colours they like, and refuse the colours they hate. So your body and mind will be healthy by using the colours you like. Or you’ll be nervous or even get ill. For example, you like blue and hate red. If you stay in a room with red windows, wallpaper and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only an hour. And, if a person walks out of a blue room and into a red room, his temperature will rise. That means our body temperature will change with different colours. 根据材料内容选择最佳答案。 1．From the experiment, we conclude that ________. A．the two boxes have the same weight B．colours can change the weight of an object C．the red paper is heavier than the white paper D．colours have different weights in people’s mind 2．What does the underlined word “wrap” mean in Chinese? A．包裹 B．安装 C．隐藏 D．围绕 3．From the fourth paragraph, we can infer ________. A．the smell of colours is changeable B．people can sense the light from colours C．people can smell the colours through the nose D．all the colours have the same smell for the blind 4．Which of the following is true? A．White colour is heavier than red colour. B．People may get ill if they refuse the colours they don’t like. C．People can stay longer in red rooms than in blue rooms. D．People’s body temperature will change with different colours. 5．We can infer from the last paragraph that ________. A．red colour is bad for our health B．people may get nervous in a red room C．blue colour can raise our body temperature D．colours can influence our mood and health Colors can affect our moods. Different colors have different effects on us. Red is the color of fire, heat, and blood. It is often associated with strong feelings like love and anger. Red can also make people feel energetic. For example, in some restaurants, the walls are painted red to encourage people to eat more. However, too much red can make people feel stressed. Blue is a calm and peaceful color. It can make people feel relaxed. Hospitals often use blue because it can help patients feel less nervous. Blue can also lower blood pressure and slow down the heart rate. But if a person is feeling sad, being in a blue room may make them feel worse. Green is the color of nature. It represents growth and harmony. Green can make people feel refreshed and balanced. In many offices, people use green plants to make the environment more comfortable. Green is also good for our eyes. When we are tired from looking at the computer screen, looking at something green can help our eyes relax. Yellow is a bright and cheerful color. It is often used to attract attention. For example, school buses are painted yellow so that they can be easily seen. Yellow can also make people feel happy and full of hope. But too much yellow can be over-stimulating and make people feel irritable. 1．What feeling does red often make people have? A．Calm. B．Relaxed. C．Energetic. D．Peaceful. 2．Why do hospitals often use blue? A．Because it can make patients feel more nervous. B．Because it can make patients feel less nervous. C．Because it can raise blood pressure.

If so, the next time you’re about to eat these delicious berries, take a good look at them. ________ ②For the most part, blueberries aren’t blue. If you carefully take off the skin of one blueberry, you’ll see that the fruit inside is white. If you rub (摩擦) the inside of the skin on a white piece of paper, you’ll see a reddish-purple color. And if you gently rub the outside of a blueberry, the blue color disappears and the berry looks almost black. But the moment you pick one, it does look blue. What’s going on? ________ ③Well, there are two ways to create colors. The first is through pigments (色素). Pigments show the color of the light they don’t take in. The most common pigment in plants is chlorophyll (叶绿素), a green pigment. Plant leaves appear green because chlorophyll doesn’t take in green light. It sends it out instead while taking in blue and red light. Plants prefer to take in blue light because it has more energy than any other light. In fact, there aren’t any “true blue” pigments in the plant world. ________ ④The second way to make color is through “structural color (结构光)”. This happens when the surface makes some colors of light look different. Have you ever seen the rainbow colors on a CD? These colors show up because of the tiny spaces between the CD’s thin layers (层). These spaces only allow certain colors to reach our eyes. ________ ⑤Blueberries also create “structural color” in their own way. The berries look black when they’re ripe (成熟的), but the plants build a thin layer of wax (蜡) on their outside. This layer is only 0.4% of a centimeter thick, but it gives the berries their blue look. The blue color helps the plants because birds are attracted to the rare color. They eat the berries and spread the seeds (种子) far and wide. ⑥Now your bowl of blueberries suddenly looks a lot more interesting. The fruit is beautiful, but its beauty is only skin deep! 1．According to the article, after you gently rub the outside of a blueberry, it almost looks ________. A．blue B．white C．black D．reddish-purple 2．Which of the following pictures correctly shows why a leaf looks green to us? A． B． C． D． 3．Blueberries appear blue in the same way that ________. A．a CD appears colorful B．a tree leaf appears green C．they appear black when ripe D．a fallen leaf appears yellow 4．The sentence “Then ask yourself: Are blueberries really blue?” should be put ________. A．at the end of Paragraph 1 B．at the end of Paragraph 2 C．at the end of Paragraph 3 D．at the end of Paragraph 4 5．Which of the following shows the structure of this passage? A．①/②③/④⑤⑥ B．①/②/③④/⑤⑥ C．①②/③④/⑤⑥ D．①/②/③④⑤/⑥ As usual, Amber was hurrying to catch the yellow school bus. Luckily the traffic lights turned green as she was to cross the road, so she made it. When the bus passed a golden arch (拱形门), it reminded her of a hamburger. She hadn’t had breakfast that morning because the fruit salad on the blue dish didn’t look delicious at all. However, Amber remembered that she was still on a diet. So now she was really in a black mood. You may have noticed that several colours were used in the above story so as to help describe Amber’s morning. In fact, colours influence your life more than you can ever imagine. Take language for example: You may describe a sick person as being “a bit green”. To describe a depressed (沮丧的) person, you say that the person is “feeling blue”. In short, colours do add interest to daily conversations. Besides, colours can be used in many parts of your daily life. Have you ever thought about why many school buses and taxis are painted yellow, and stop signs red? Since yellow is the most eye-catching colour, it can catch people’s attention, especially in heavy traffic. As for red, it is the colour which usually shows warning. As a result, some traffic signs use this colour. For the same reason, hot- water taps are usually marked red. The colours of a dining environment possibly decide how much you eat. Most fast-food restaurants are often decorated in bright colours such as red, yellow, orange, and white for the purpose of increasing people’s appetites (胃口). This is because bright colours are natural colours found in many foods, and, therefore, able to raise people’s spirits. Blue, in comparison (对比) with bright colours, is said to lower people’s appetites because few foods are blue in nature. For those who are on a diet, blue dishes and bowls might help! “Morning, Amber! What happened? You look a bit green,” said Violet, Amber’s best friend. “Nothing…just feeling…blue,” said Amber. “Hey! Come to my place tonight. Do you know what I just bought? A phone! It’s red-hot.” Amber was tickled pink to have the chance to play with the phone and said, “Sounds great!” 1．According to the passage, if you are on a diet, ________ might help. A．putting your food in a blue dish or bowl B．turning on a yellow light during the meal C．painting the walls of the dining room white D．covering the dining table with an orange cloth 2．Most school buses are painted yellow because ________. A．it tells other drivers to prepare to stop B．it helps bus drivers stay in a good mood C．it can easily catch other people’s attention D．it is the colour that most school children like 3．Which of the following is NOT mentioned in the passage? A．Colours influence people’s daily lives. B．Most fast-food restaurants are painted grey. C．Different colours are used for different purposes. D．Colours make daily conversations more interesting. From red apples and yellow lemons to blueberries and green melons, fruit comes in many different colors. Why do different kinds of fruit have different colors? According to Lu Wei, a Chinese scientist, fruit colors actually come from their different pigments (色素). These pigments appear differently, depending on the fruit’s environment. This causes the fruit to turn a certain color. To find out how environment influences fruit colors, Chinese scientists studied more than 280 different fruit colors. They found that red fruit usually grows in cooler places. Also, you can find red fruit growing in many places around the world instead of just growing in one place. Blue and purple fruit mostly grows in warm places. Yellow and green fruit often grows in hot places. The scientists also found that the closer the fruit is to the equator (赤道), the darker its color will be. ▲ Animals eat fruit and drop the seeds (种子) in other places. This helps the fruit spread and grow in different places. Therefore, in order to attract animals, some fruit develop colors that are easy for animals to see. However, animals see colors in a different way. Fruit needs to develop colors that are suitable for animals’ seeing abilities. For example, birds can see red more easily than humans do. Therefore, there is more red fruit in areas where birds live. The lemurs (狐猴) of Madagascar are red-green color-blind. Many yellow fruit can be found there, as they can easily see this color. 1．You are more likely to find red fruit in ________ places. A．warmer B．cooler C．higher D．lower 2．Which kind of fruit mostly grows in warm places? A． B． C． D． 3．Which of the following can be put in “ ▲ ” in Paragraph 4? A．All the fruit and animals help each other. B．Fruit in the wild is much more colorful. C．But not all animals are interested in colors. D．Animals also has an influence on fruit colors. 4．What does the underlined word “suitable” mean in Paragraph 5? A．Proper. B．Difficult. C．Funny. D．Healthy. 5．What’s the best title for this passage? A．Why does Fruit Often Change Colors? B．Why does Fruit Have Different Colors? C．How does Environment Influence Fruit Colors? D．How do Animals Influence Fruit Colors? The natural world is colorful with humans, plants and animals showing different colors. Human skin can be many different colors and it changes with the sun, our feelings, or our health. This is because of pigments (色素), which reflect light and make what the eye sees as colors. So, when we feel excited or angry, our heart send more blood to the face and the pigments in the skin become red. Plants also have pigments. Colors plays an important role in their life. The bright colors of flowers catch the attention of insects, which then carry their pollen (花粉) from one flower to another. Bees can see colors we cannot, and they follow these to the inside of the flower. Without bees visiting flowers in this way, many plants would die out. Animals also use colors for their own need. They protect themselves with different colors in order not to be seen by predators (捕食者). However, some animals use the color as a warning to frighten predators away. Bright colors such as yellow and red are often used in this way. So, we can see that there may be many different reasons and uses for colors in the natural world. Some uses of colors in nature remain unknown, but one thing is for sure, colors not only make our planet beautiful, but they are also necessary for our planet to live on. 1．What’s the underlined “it” refer to ________? A．color B．skin C．light D．pigments 2．What helps plants to attract insects? A．Leaves. B．Colors. C．Fruits. D．Pollen. 3．What’s the structure of this passage? A． B． C． D． 4．Where can you find this text? A．In an art book. B．In a health report. C．In a TV program. D．In a science magazine. In English, when someone is very angry, we say this person sees red, like the way a bull (公牛) goes wild after seeing a red cloth. Now it turns out that seeing red is not just an expression for angry people, but also a scientific fact. Researchers found that there is a connection between the color red and anger. Angry people really see red where others don’t. And a special love for red over blue may even suggest a more hostile (敌对的) personality. The study includes a number of experiments. At first, researchers asked a group of people which colour they preferred, red or blue. Participants (参与者) then did personality tests. Results showed that those who chose red seemed to be more hostile. During a second test, participants looked at faded (褪色的) images that could be seen as either red or blue. Those who saw red scored 25 percent higher on hostility in the personality test. “Hostile people have hostile thoughts. Hostile thoughts are connected with the colour red, and so hostile people see this colour more often.” the researchers said. Finally, the participants were told about imaginary situations in which they could take different actions. Results showed that in these situations, red-preferring people were more likely to show that they would hurt another person than those who preferred blue. 1．What may people be like if they prefer the colour red over blue according to the passage? A．They get angry easily. B．They have strange thoughts. C．They are good at taking actions. D．They are good at doing experiments. 2．How do the researchers prove the person who loves red may have more hostility? A．By making interviews. B．By listing numbers. C．By doing experiments. D．By giving examples. 3．What’s the best title of the passage? A．Hostile People B．Red and Blue C．People Who Prefer Red D．Meanings of Different Colours There are many colours in nature. But do you know if a colour has weight? I think you’ll say “No”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment. First, put two objects with the same weight into two boxes. Then cover the box. Third, wrap one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier. Why do you think so? A scientist found different colours have different weight in a man’s mind. So he did many tests and at last he got the result. That’s to say, every colour has its own weight in our mind and the order is the same. The heaviest colour is red. then blue, green, orange, yellow and white. The scientist told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientist say so? That is because every colour stands for a kind of light with a certain wavelength (波长). It reaches our brain through sense organs (感觉器官). According to this discovery, scientists say that people accept the colours they like, and refuse the colours they hate. So your body and mind will be healthy by using the colours you like. Or you’ll be nervous or even get ill. For example, if you stay in a room with red windows, wallpaper and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only an hour. That means our body temperature will change with different colours. 1．In people’s mind, different colours have different weight. Orange is heavier than________. A．blue B．red C．yellow D．green 2．The purpose of the second paragraph is to tell us A．a red box is heavier than n white one B．a colour has weight in one’s mind C．white paper is lighter than red paper D．you can know the weight of a colour by holding it 3．Why did the scientist say colours have smell? A．Because people can sense the light from colours. B．Because we can smell colours with our nose. C．Because every colour has its own sweet smell D．Because every colour can give off light of the same length. 4．What would be the best title for the passage? A．How can we weigh an object? B．Do colours have weight and smell? C．Are colours really good for our health? D．What is the relationship between weight and smell? 重难语篇提升练 Colour psychology (心理学) is the study of the influences that colours have on what humans behave and feel. There have been many experiments with colour since it was discovered in 1666. How does colour influence your mood? Let’s take a deeper dive into colour psychology. Colour Influences on Mood Colour has more influence in our lives than we realize. It can influence our minds, bodies, and moods. Colours close to the red spectrum (光谱) are warmer colours, including red, orange, and yellow. These warm colours suggest feelings of warmth, comfort, anger and hostility (敌意). While blue colours like purple and green are known for suggesting feelings of calm, sadness, or coldness. Colour Therapy Colour Psychology can also be used as a therapy. In fact, old cultures practiced something called Chromotherapy, or light medicine, which uses colours to cure. However, even though some psychologists look at colour therapy doubtfully, it is still used today in some medical practices. Research has shown that the “mood-changing effect” of colour may not last (持续) long in many cases. A blue room may cause feelings of calm at the beginning, but the effect disappears after a short period. Studies have also shown that colour can influence your performance. A study was done in six experiments using 71 college students who were given a number. Each number was coloured red, green, or black before taking a five-minute test. Of those uncovered to the colour red before taking an exam, it was shown to harm their performance in the test. Colour in Consumption (消费) We also see colour psychology in advertising, suggesting that some colours or shades can have a wide influence, improving our moods or causing worries. However, the colour of the products we buy may have something to do with our personality and why we choose the product. From the clothes we wear, to the car we drive-the colour can tell about how people notice us. For example, some realize the colour black is powerful. When we think of expensive cars, most of them are black. Colour has played an important part in sending information and even influencing our decisions. Interest in colour psychology is growing, and there is still a lot to learn how it can influence our moods, buys, and performance. 1．According to the passage, what is colour psychology? A．It studies how scientists are influenced by different colours. B．It studies how colours influence human’s actions and moods. C．It studies how to divide colours into different groups. D．It studies how to do experiments with different colours. 2．Which of the following is TRUE about colour therapy? A．All psychologists find colour therapy useful. B．People in old times knew nothing about colour therapy. C．The influence of colour therapy may not last long. D．Red can help students get good marks in exams. 3．What can we infer from the passage? A．We can tell a person’s personality according to their preferred colour. B．Most customers would like to buy black cars instead of white ones. C．The colour of products has something to do with their product quality. D．Most companies prefer to use the colour black in the advertisements. 4．In which section of a website can we probably read the passage? A．Travel guide B．News report C．Business D．Science Have you ever wondered if you see the same colours as other people? Most people know what blue is when they see it. It’s the colour of the sea and the sky. They see the colour and call it “blue” because they were taught the word and connected it with what they saw. But how do you know what you see as “blue” isn’t someone else’s “red”? The ability to notice different colours is due to receptors (感受器) in our eyes which is also called cones (晶体). Light waves hit these receptors and they react depending on which colour the light is, sending signals to the brain. The brain then translates these signals to tell which colour light the eyes are receiving. Some people’s receptors are more developed than others. People with weaker receptors usually have colour blindness. Those with more developed receptors can see more shades of one colour, which is the first way in which people may see colours differently from each other. We sometimes hear people having an argument (争论) about whether something is dark blue or black. It might be because one person has stronger receptors to translate the light than another. In the past, most scientists would think that everyone saw colours in the same way. However, later scientists carried out a research on monkeys, in which they were injected (注射) with a virus affecting their receptors. They found that monkeys could see one more color—red, compared (比较) with the usual two colors—blue and green. This is because the neurons (神经元) in their brains automatically (自动地) adapted (适应) to be able to understand a new colour. This also might mean the neurons in human brains are not hardwired (与生俱来的) to understand which colour is which. Our brains and neurons may adapt to tell colors depending on stimulus (刺激物) . Colour could be a very personal experience, unique (独一无二的) to everyone. So next time when you and your friend talk about your favourite colour, if yours is blue and your friend says red, you might actually be thinking about the same colour. 1．How does the author introduce his topic in Paragraph 1? A．By doing a survey. B．By listing some numbers. C．By giving an example. D．By using famous people’s words. 2．What’s the correct process (过程) of seeing colors? A．cones send signals to the brain→the brain translates the signals→light waves hit cones→cones react to the light. B．light waves hit cones→cones react to the light→cones send signals to the brain→the brain translates the signals. C．light waves hit cones→cones send signals to the brain→the brain translates the signals→cones react to the light. D．cones react to the light→cones send signals to the brain→light waves hit cones→cones react to the light. 3．Which of the following is TRUE according to the passage? A．People with weaker receptors are more likely to have colour blindness. B．Our eyes are born to automatically tell colors. C．Monkeys can usually see three colors. D．Now most scientists still believe that everyone sees colors in the same way. 4．Which graph (图表) shows how the author organizes his ideas? A． B． C． D． 学科网（北京）股份有限公司 $ Unit 2 Colours 单元话题阅读理解练习 Unit 2 Colours 单元话题：颜色 本资料共10篇专题训练，从上到下依次按照难度分为基础语篇巩固练和重难语篇提升练 基础语篇巩固练 There are many colours in nature.

Different colors have different effects on us”，后文分别围绕红、蓝、绿、黄四种颜色，具体阐述每种颜色对情绪的不同影响，始终围绕“不同颜色对情绪有不同影响”展开。故选A。 ①Do you like blueberries? If so, the next time you’re about to eat these delicious berries, take a good look at them. ________ ②For the most part, blueberries aren’t blue. If you carefully take off the skin of one blueberry, you’ll see that the fruit inside is white. If you rub (摩擦) the inside of the skin on a white piece of paper, you’ll see a reddish-purple color. And if you gently rub the outside of a blueberry, the blue color disappears and the berry looks almost black. But the moment you pick one, it does look blue. What’s going on? ________ ③Well, there are two ways to create colors. The first is through pigments (色素). Pigments show the color of the light they don’t take in. The most common pigment in plants is chlorophyll (叶绿素), a green pigment. Plant leaves appear green because chlorophyll doesn’t take in green light. It sends it out instead while taking in blue and red light. Plants prefer to take in blue light because it has more energy than any other light. In fact, there aren’t any “true blue” pigments in the plant world. ________ ④The second way to make color is through “structural color (结构光)”. This happens when the surface makes some colors of light look different. Have you ever seen the rainbow colors on a CD? These colors show up because of the tiny spaces between the CD’s thin layers (层). These spaces only allow certain colors to reach our eyes. ________ ⑤Blueberries also create “structural color” in their own way. The berries look black when they’re ripe (成熟的), but the plants build a thin layer of wax (蜡) on their outside. This layer is only 0.4% of a centimeter thick, but it gives the berries their blue look. The blue color helps the plants because birds are attracted to the rare color. They eat the berries and spread the seeds (种子) far and wide. ⑥Now your bowl of blueberries suddenly looks a lot more interesting. The fruit is beautiful, but its beauty is only skin deep! 1．According to the article, after you gently rub the outside of a blueberry, it almost looks ________. A．blue B．white C．black D．reddish-purple 2．Which of the following pictures correctly shows why a leaf looks green to us? A． B． C． D． 3．Blueberries appear blue in the same way that ________. A．a CD appears colorful B．a tree leaf appears green C．they appear black when ripe D．a fallen leaf appears yellow 4．The sentence “Then ask yourself: Are blueberries really blue?” should be put ________. A．at the end of Paragraph 1 B．at the end of Paragraph 2 C．at the end of Paragraph 3 D．at the end of Paragraph 4 5．Which of the following shows the structure of this passage? A．①/②③/④⑤⑥ B．①/②/③④/⑤⑥ C．①②/③④/⑤⑥ D．①/②/③④⑤/⑥ 【答案】1．C 2．B 3．A 4．A 5．D 【导语】本文主要介绍蓝莓呈蓝色的原因。 1．细节理解题。根据“And if you gently rub the outside of a blueberry, the blue color disappears and the berry looks almost black.”可知，轻轻擦拭蓝莓的外部后，它几乎看起来是黑色的。故选C。 2．推理判断题。根据“Plant leaves appear green because chlorophyll doesn’t take in green light. It sends it out instead while taking in blue and red light.”可知，植物叶子呈绿色是因为叶片中含有叶绿素，而叶绿素主要吸收红光和蓝光，不吸收绿光，故而绿光被反射回来，使得叶片呈绿色，可推知，B项符合。故选B。 3．细节理解题。根据“The second way to make color is through ‘structural color (结构光)’…Have you ever seen the rainbow colors on a CD? These colors show up because of the tiny spaces between the CD’s thin layers (层).”以及“Blueberries also create “structural color” in their own way.”可知，蓝莓呈现蓝色，就像CD呈现彩色一样，两者都是通过“结构光”制造颜色。故选A。 4．推理判断题。根据第一段“Do you like blueberries? If so, the next time you’re about to eat these delicious berries, take a good look at them.”及下文“For the most part, blueberries aren’t blue.”可知，此处承上启下，引出蓝色这一话题。故选A。 5．篇章结构题。通读全文可知，第一段主要讲述吃蓝莓时，看到蓝莓的颜色是蓝色；第二段主要讲述剥开蓝莓或者轻轻擦拭蓝莓的外部，这时看到的颜色都不是蓝色的；第三段到第五段讲述创造颜色的两种方法和蓝莓创造颜色的方法；最后一段总结全文。故选D。 As usual, Amber was hurrying to catch the yellow school bus. Luckily the traffic lights turned green as she was to cross the road, so she made it. When the bus passed a golden arch (拱形门), it reminded her of a hamburger. She hadn’t had breakfast that morning because the fruit salad on the blue dish didn’t look delicious at all. However, Amber remembered that she was still on a diet. So now she was really in a black mood. You may have noticed that several colours were used in the above story so as to help describe Amber’s morning. In fact, colours influence your life more than you can ever imagine. Take language for example: You may describe a sick person as being “a bit green”. To describe a depressed (沮丧的) person, you say that the person is “feeling blue”. In short, colours do add interest to daily conversations. Besides, colours can be used in many parts of your daily life. Have you ever thought about why many school buses and taxis are painted yellow, and stop signs red? Since yellow is the most eye-catching colour, it can catch people’s attention, especially in heavy traffic. As for red, it is the colour which usually shows warning. As a result, some traffic signs use this colour. For the same reason, hot- water taps are usually marked red. The colours of a dining environment possibly decide how much you eat. Most fast-food restaurants are often decorated in bright colours such as red, yellow, orange, and white for the purpose of increasing people’s appetites (胃口). This is because bright colours are natural colours found in many foods, and, therefore, able to raise people’s spirits. Blue, in comparison (对比) with bright colours, is said to lower people’s appetites because few foods are blue in nature. For those who are on a diet, blue dishes and bowls might help! “Morning, Amber! What happened? You look a bit green,” said Violet, Amber’s best friend. “Nothing…just feeling…blue,” said Amber. “Hey! Come to my place tonight. Do you know what I just bought? A phone! It’s red-hot.” Amber was tickled pink to have the chance to play with the phone and said, “Sounds great!” 1．According to the passage, if you are on a diet, ________ might help. A．putting your food in a blue dish or bowl B．turning on a yellow light during the meal C．painting the walls of the dining room white D．covering the dining table with an orange cloth 2．Most school buses are painted yellow because ________. A．it tells other drivers to prepare to stop B．it helps bus drivers stay in a good mood C．it can easily catch other people’s attention D．it is the colour that most school children like 3．Which of the following is NOT mentioned in the passage? A．Colours influence people’s daily lives. B．Most fast-food restaurants are painted grey. C．Different colours are used for different purposes. D．Colours make daily conversations more interesting. 【答案】1．A 2．C 3．B 【导语】本文介绍了颜色对生活各方面的影响，包括语言表达、交通工具及标志的配色、饮食环境的色彩对食欲的影响等。 1．细节理解题。根据文章内容“For those who are on a diet, blue dishes and bowls might help!”可知，节食的人使用蓝色的碟子和碗可能会抑制食欲。故选A。 2．细节理解题。根据“Since yellow is the most eye-catching colour, it can catch people’s attention, especially in heavy traffic.”可知，黄色是最显眼的颜色，能够迅速引起人们的注意，特别是在繁忙的交通中。故选C。 3．细节理解题。根据“Most fast-food restaurants are often decorated in bright colours such as red, yellow, orange, and white for the purpose of increasing people’s appetites.”可知，大部分地快餐店都喜欢装修成鲜艳的红、黄、橙和白等颜色，而没有提到灰色，因此选项B没有在文中提到。故选B。 From red apples and yellow lemons to blueberries and green melons, fruit comes in many different colors. Why do different kinds of fruit have different colors? According to Lu Wei, a Chinese scientist, fruit colors actually come from their different pigments (色素). These pigments appear differently, depending on the fruit’s environment. This causes the fruit to turn a certain color. To find out how environment influences fruit colors, Chinese scientists studied more than 280 different fruit colors. They found that red fruit usually grows in cooler places. Also, you can find red fruit growing in many places around the world instead of just growing in one place. Blue and purple fruit mostly grows in warm places. Yellow and green fruit often grows in hot places. The scientists also found that the closer the fruit is to the equator (赤道), the darker its color will be. ▲ Animals eat fruit and drop the seeds (种子) in other places. This helps the fruit spread and grow in different places. Therefore, in order to attract animals, some fruit develop colors that are easy for animals to see. However, animals see colors in a different way. Fruit needs to develop colors that are suitable for animals’ seeing abilities. For example, birds can see red more easily than humans do. Therefore, there is more red fruit in areas where birds live. The lemurs (狐猴) of Madagascar are red-green color-blind. Many yellow fruit can be found there, as they can easily see this color. 1．You are more likely to find red fruit in ________ places. A．warmer B．cooler C．higher D．lower 2．Which kind of fruit mostly grows in warm places? A． B． C． D． 3．Which of the following can be put in “ ▲ ” in Paragraph 4? A．All the fruit and animals help each other. B．Fruit in the wild is much more colorful. C．But not all animals are interested in colors. D．Animals also has an influence on fruit colors. 4．What does the underlined word “suitable” mean in Paragraph 5? A．Proper. B．Difficult. C．Funny. D．Healthy. 5．What’s the best title for this passage? A．Why does Fruit Often Change Colors? B．Why does Fruit Have Different Colors? C．How does Environment Influence Fruit Colors? D．How do Animals Influence Fruit Colors? 【答案】1．B 2．C 3．D 4．A 5．B 【导语】本文是一篇说明文，主要讲述了水果有不同颜色的原因。 1．细节理解题。根据“They found that red fruit usually grows in cooler places.”可知更可能在比较凉爽的地方找到红色的水果。故选B。 2．推理判断题。根据“Blue and purple fruit mostly grows in warm places.”可知更可能在比较暖和的地方找到蓝色和紫色的水果，选项中葡萄是紫色的。故选C。 3．推理判断题。根据“Animals eat fruit and drop the seeds in other places. This helps the fruit spread and grow in different places. Therefore, in order to attract animals, some fruit develop colors that are easy for animals to see.”可知，此处为段首句是全段的概括，本段都在说动物对水果颜色的影响，选项D“Animals also has an influence on fruit colors.”符合题意。故选D。 4．词句猜测题。根据“Fruit needs to develop colors that are suitable for animals’ seeing abilities. For example, birds can see red more easily than humans do.”可知，鸟能比人类更容易看到红色，水果需要发展出“适合”动物视觉能力的颜色，Proper“合适的”符合题意。故选A。 5．最佳标题题。根据“Why do different kinds of fruit have different colors?”及全文内容可知本文主要讲述了水果有不同颜色的原因。用“Why does Fruit Have Different Colors?”做标题最合适。故选B。 The natural world is colorful with humans, plants and animals showing different colors. Human skin can be many different colors and it changes with the sun, our feelings, or our health. This is because of pigments (色素), which reflect light and make what the eye sees as colors. So, when we feel excited or angry, our heart send more blood to the face and the pigments in the skin become red. Plants also have pigments. Colors plays an important role in their life. The bright colors of flowers catch the attention of insects, which then carry their pollen (花粉) from one flower to another. Bees can see colors we cannot, and they follow these to the inside of the flower. Without bees visiting flowers in this way, many plants would die out. Animals also use colors for their own need. They protect themselves with different colors in order not to be seen by predators (捕食者). However, some animals use the color as a warning to frighten predators away. Bright colors such as yellow and red are often used in this way. So, we can see that there may be many different reasons and uses for colors in the natural world. Some uses of colors in nature remain unknown, but one thing is for sure, colors not only make our planet beautiful, but they are also necessary for our planet to live on. 1．What’s the underlined “it” refer to ________? A．color B．skin C．light D．pigments 2．What helps plants to attract insects? A．Leaves. B．Colors. C．Fruits. D．Pollen. 3．What’s the structure of this passage? A． B． C． D． 4．Where can you find this text? A．In an art book. B．In a health report. C．In a TV program. D．In a science magazine. 【答案】1．B 2．B 3．A 4．D 【导语】本文是一篇说明文，主要介绍颜色在自然界中用途及原因。 1．词句猜测题。根据“Human skin can be many different colors and it changes with the sun, our feelings, or our health.”可知，这里的it所在句子描述的是前面提到的Human skin，说皮肤会随着一些因素而变化。 故选B。 2．细节理解题。根据“Plants also have pigments.  Colors plays an important role in their life. The bright colors of  flowers catch the attention of insects, which then carry their pollen from one flower to another.”可知，植物使用颜色吸引昆虫。故选B。 3．篇章结构题。文章第一段先总体阐述自然界因人类、植物和动物呈现出不同颜色而丰富多彩，是总起引出话题；接着第二段介绍人类皮肤颜色变化与色素相关，第三段讲植物利用颜色吸引昆虫等，第四段说动物使用颜色保护自己或警示捕食者，这三段是分别从人类、植物、动物三个方面具体举例说明自然界中颜色的不同情况及用途，属于分述内容；最后一段总结强调自然界中颜色有诸多原因和用途，且对地球很重要，是总结全文。 可知整体结构是“总—分—总”。故选A。 4．推理判断题。通读全文，尤其根据第四段“So, we can see that there may be many different reasons and uses for colors in the natural world.”可知本文主要介绍了自然界中的颜色可能有许多不同的原因和用途，故推测应该能在一本科学杂志上找到这样的文章。故选D。 In English, when someone is very angry, we say this person sees red, like the way a bull (公牛) goes wild after seeing a red cloth. Now it turns out that seeing red is not just an expression for angry people, but also a scientific fact. Researchers found that there is a connection between the color red and anger. Angry people really see red where others don’t. And a special love for red over blue may even suggest a more hostile (敌对的) personality. The study includes a number of experiments. At first, researchers asked a group of people which colour they preferred, red or blue. Participants (参与者) then did personality tests. Results showed that those who chose red seemed to be more hostile. During a second test, participants looked at faded (褪色的) images that could be seen as either red or blue. Those who saw red scored 25 percent higher on hostility in the personality test. “Hostile people have hostile thoughts. Hostile thoughts are connected with the colour red, and so hostile people see this colour more often.” the researchers said. Finally, the participants were told about imaginary situations in which they could take different actions. Results showed that in these situations, red-preferring people were more likely to show that they would hurt another person than those who preferred blue. 1．What may people be like if they prefer the colour red over blue according to the passage? A．They get angry easily. B．They have strange thoughts. C．They are good at taking actions. D．They are good at doing experiments. 2．How do the researchers prove the person who loves red may have more hostility? A．By making interviews. B．By listing numbers. C．By doing experiments. D．By giving examples. 3．What’s the best title of the passage? A．Hostile People B．Red and Blue C．People Who Prefer Red D．Meanings of Different Colours 【答案】1．A 2．C 3．C 【导语】本文是一篇说明文，介绍了在英语中“see red”表示愤怒不是虚言，而是科学事实。 1．细节理解题。根据“And a special love for red over blue may even suggest a more hostile personality.”可知，说明偏爱红色的人可能更具敌意，也就是容易生气，故选A。 2．细节理解题。从“The study includes a number of experiments.”可知，研究人员通过做实验来证明喜爱红色的人可能更具敌意，故选C。 3．最佳标题题。文章主要围绕红色与敌意的关系展开，C选项“偏爱红色的人”符合文章大意，故选C。 There are many colours in nature. But do you know if a colour has weight? I think you’ll say “No”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment. First, put two objects with the same weight into two boxes. Then cover the box. Third, wrap one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier. Why do you think so? A scientist found different colours have different weight in a man’s mind. So he did many tests and at last he got the result. That’s to say, every colour has its own weight in our mind and the order is the same. The heaviest colour is red. then blue, green, orange, yellow and white. The scientist told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientist say so? That is because every colour stands for a kind of light with a certain wavelength (波长). It reaches our brain through sense organs (感觉器官). According to this discovery, scientists say that people accept the colours they like, and refuse the colours they hate. So your body and mind will be healthy by using the colours you like. Or you’ll be nervous or even get ill. For example, if you stay in a room with red windows, wallpaper and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only an hour. That means our body temperature will change with different colours. 1．In people’s mind, different colours have different weight. Orange is heavier than________. A．blue B．red C．yellow D．green 2．The purpose of the second paragraph is to tell us A．a red box is heavier than n white one B．a colour has weight in one’s mind C．white paper is lighter than red paper D．you can know the weight of a colour by holding it 3．Why did the scientist say colours have smell? A．Because people can sense the light from colours. B．Because we can smell colours with our nose. C．Because every colour has its own sweet smell D．Because every colour can give off light of the same length. 4．What would be the best title for the passage? A．How can we weigh an object? B．Do colours have weight and smell? C．Are colours really good for our health? D．What is the relationship between weight and smell? 【答案】1．C 2．B 3．A 4．B 【导语】本文是一篇说明文，介绍了颜色在人们心中具有不同的重量以及科学家对颜色相关特性的一些研究发现。 1．细节理解题。根据“The heaviest colour is red, then blue, green, orange, yellow and white.”可知，在人们心中橙色比黄色重，故选C。 2．主旨大意题。第二段通过实验让人们感受两个相同重量的盒子，一个用红纸包裹，一个用白纸包裹，人们会觉得红色的更重，目的是为了说明颜色在人的心中是有重量的，故选B。 3．细节理解题。根据“That is because every colour stands for a kind of light with a certain wavelength. It reaches our brain through sense organs.”可知，科学家说颜色有气味是因为人们能感知到颜色所代表的具有一定波长的光，故选A。 4．最佳标题题。文章主要围绕颜色是否有重量和气味展开，最佳标题为“颜色有重量和气味吗？”，故选B。 重难语篇提升练 Colour psychology (心理学) is the study of the influences that colours have on what humans behave and feel. There have been many experiments with colour since it was discovered in 1666. How does colour influence your mood? Let’s take a deeper dive into colour psychology. Colour Influences on Mood Colour has more influence in our lives than we realize. It can influence our minds, bodies, and moods. Colours close to the red spectrum (光谱) are warmer colours, including red, orange, and yellow. These warm colours suggest feelings of warmth, comfort, anger and hostility (敌意). While blue colours like purple and green are known for suggesting feelings of calm, sadness, or coldness. Colour Therapy Colour Psychology can also be used as a therapy. In fact, old cultures practiced something called Chromotherapy, or light medicine, which uses colours to cure. However, even though some psychologists look at colour therapy doubtfully, it is still used today in some medical practices. Research has shown that the “mood-changing effect” of colour may not last (持续) long in many cases. A blue room may cause feelings of calm at the beginning, but the effect disappears after a short period. Studies have also shown that colour can influence your performance. A study was done in six experiments using 71 college students who were given a number. Each number was coloured red, green, or black before taking a five-minute test. Of those uncovered to the colour red before taking an exam, it was shown to harm their performance in the test. Colour in Consumption (消费) We also see colour psychology in advertising, suggesting that some colours or shades can have a wide influence, improving our moods or causing worries. However, the colour of the products we buy may have something to do with our personality and why we choose the product. From the clothes we wear, to the car we drive-the colour can tell about how people notice us. For example, some realize the colour black is powerful. When we think of expensive cars, most of them are black. Colour has played an important part in sending information and even influencing our decisions. Interest in colour psychology is growing, and there is still a lot to learn how it can influence our moods, buys, and performance. 1．According to the passage, what is colour psychology? A．It studies how scientists are influenced by different colours. B．It studies how colours influence human’s actions and moods. C．It studies how to divide colours into different groups. D．It studies how to do experiments with different colours. 2．Which of the following is TRUE about colour therapy? A．All psychologists find colour therapy useful. B．People in old times knew nothing about colour therapy. C．The influence of colour therapy may not last long. D．Red can help students get good marks in exams. 3．What can we infer from the passage? A．We can tell a person’s personality according to their preferred colour. B．Most customers would like to buy black cars instead of white ones. C．The colour of products has something to do with their product quality. D．Most companies prefer to use the colour black in the advertisements. 4．In which section of a website can we probably read the passage? A．Travel guide B．News report C．Business D．Science 【答案】1．B 2．C 3．A 4．D 【导语】本文主要讲述了颜色心理学研究颜色对人类行为和感觉的影响。并且人们对色彩心理学的兴趣越来越大，它如何影响我们的情绪、购买和表现还有很多需要学习的地方。 1．细节理解题。根据“Colour psychology is the study of the influences that colours have on what humans behave and feel.”可知，颜色心理学研究颜色对人类行为和感觉的影响。选项B“它研究颜色如何影响人类的行为和情绪。”符合题意。故选B。 2．细节理解题。根据“Research has shown that the ‘mood-changing effect’ of colour may not last long in many cases.”可知，颜色的“情绪变化效应”可能不会持续很久。选项C“色彩疗法的影响可能不会持续太久。”正确。故选C。 3．推理判断题。根据“However, the colour of the products we buy may have something to do with our personality and why we choose the product.”可知，我们购买的产品的颜色可能与我们的个性以及我们选择该产品的原因有关。故选A。 4．推理判断题。根据“Colour psychology is the study of the influences that colours have on what humans behave and feel. There have been many experiments with colour since it was discovered in 1666.”可知，颜色心理学研究颜色对人类行为和感觉的影响，自从颜色在1666年被发现以来，已经有过许多关于颜色的实验。因此，本篇文章可能出自科学的一部分。故选D。 Have you ever wondered if you see the same colours as other people? Most people know what blue is when they see it. It’s the colour of the sea and the sky. They see the colour and call it “blue” because they were taught the word and connected it with what they saw. But how do you know what you see as “blue” isn’t someone else’s “red”? The ability to notice different colours is due to receptors (感受器) in our eyes which is also called cones (晶体). Light waves hit these receptors and they react depending on which colour the light is, sending signals to the brain. The brain then translates these signals to tell which colour light the eyes are receiving. Some people’s receptors are more developed than others. People with weaker receptors usually have colour blindness. Those with more developed receptors can see more shades of one colour, which is the first way in which people may see colours differently from each other. We sometimes hear people having an argument (争论) about whether something is dark blue or black. It might be because one person has stronger receptors to translate the light than another. In the past, most scientists would think that everyone saw colours in the same way. However, later scientists carried out a research on monkeys, in which they were injected (注射) with a virus affecting their receptors. They found that monkeys could see one more color—red, compared (比较) with the usual two colors—blue and green. This is because the neurons (神经元) in their brains automatically (自动地) adapted (适应) to be able to understand a new colour. This also might mean the neurons in human brains are not hardwired (与生俱来的) to understand which colour is which. Our brains and neurons may adapt to tell colors depending on stimulus (刺激物) . Colour could be a very personal experience, unique (独一无二的) to everyone. So next time when you and your friend talk about your favourite colour, if yours is blue and your friend says red, you might actually be thinking about the same colour. 1．How does the author introduce his topic in Paragraph 1? A．By doing a survey. B．By listing some numbers. C．By giving an example. D．By using famous people’s words. 2．What’s the correct process (过程) of seeing colors? A．cones send signals to the brain→the brain translates the signals→light waves hit cones→cones react to the light. B．light waves hit cones→cones react to the light→cones send signals to the brain→the brain translates the signals. C．light waves hit cones→cones send signals to the brain→the brain translates the signals→cones react to the light. D．cones react to the light→cones send signals to the brain→light waves hit cones→cones react to the light. 3．Which of the following is TRUE according to the passage? A．People with weaker receptors are more likely to have colour blindness. B．Our eyes are born to automatically tell colors. C．Monkeys can usually see three colors. D．Now most scientists still believe that everyone sees colors in the same way. 4．Which graph (图表) shows how the author organizes his ideas? A． B． C． D． 【答案】1．C 2．B 3．A 4．D 【导语】本文主要讨论了人们看到的颜色是否相同，解释了眼睛中的感受器如何工作，以及为什么有些人可能看到的颜色不同。 1．细节理解题。根据第一段“Most people know what blue is when they see it.”可知，作者在第一段通过举例介绍他的主题。故选C。 2．细节理解题。根据第二段“The ability to notice different colours is due to receptors (感受器) in our eyes which is also called cones (晶体). Light waves hit these receptors and they react depending on which colour the light is, sending signals to the brain. The brain then translates these signals to tell which colour light the eyes are receiving.”可知，看颜色的正确过程应为：光波撞击视锥细胞→视锥细胞对光做出反应→视锥细胞向大脑发送信号→大脑翻译信号。故选B。 3．细节理解题。根据第三段“People with weaker receptors usually have colour blindness.”可知，受体较弱的人通常患有色盲，选项A表述正确。故选A。 4．篇章结构题。通读全文可知，第一段介绍了人们是否看到的颜色相同，引出主题；第二、三、四段具体介绍了眼睛中的感受器如何工作，以及为什么有些人可能看到的颜色不同；最后一段总结指出颜色可能是一种非常个人化的体验，对每个人来说都是独特的。因此文章结构为总→分→总结构，D选项符合题意。故选D。 学科网（北京）股份有限公司 $
