One day I ran away from home and stayed outside for a few hours. When I returned home at night, I saw all the pain, anger and disappointment on my mother’s face. We knew that we were in great need of talk. We agreed to have breakfast together the next morning. In the end we decided to go to a restaurant. On our way to the restaurant, I noticed my mother had two notebooks in her hands. I asked her what they were used for. She explained to me that sometimes it was easier to write down our feelings than to talk about them. We should write down our feelings. Our first topic was “Why am I so angry?” I wrote a half page, and my mom filled up nearly three pages. I saw the tears run down her face while she was writing. I never realized anyone could hide so much anger. After we finished writing, we exchanged our notebooks. As soon as I started reading my mother’s words, we discussed our feelings. Finally, it felt like all the anger inside me went away from my body. Our talk helped me realize so many things I had never thought of before, not only about my mother but also about other people. My mother and I continue using our notebooks as a way of communicating. We know that no matter how we feel about each other, our notebooks are a safe place to express our feelings. We have come to an agreement that we write “I love you” at the end of each letter.

What makes us study and make progress each day is closely connected with our personal dream and goal. But why do you have dreams and goals, you still end up with nothing? This is the famous formula (公式) for success: Dream > Believe > Achieve Most people have what they want (Dream) and think they can realize their dreams (Believe). And then they do nothing. They just imagine their dreams can come true. When they get tired waiting and lose a lot, they get bored. They say angrily how terrible their life is. I personally believe that if you really want to achieve your dreams and goals in life, you have to add one thing to your success formula: Dream > Believe > Act > Achieve For me, act is the most important thing for success and that’s to Take Persistent (锲而不舍的) Action (Act). If you say, “I can’t do it” and give up, you can never do anything valuable. However, “I’ll try” creates wonders. Let’s remember that there will be obstacles in our life. We must face them 原创精品资源学科网独家享有版权，侵权必究！ 3 bravely and solve them. Success is not something that falls down from the sky.

A．Doing Something Valuable B．Studying Hard and Making Progress C．Realizing Dreams with Persistent Action D．Facing Difficulties Bravely Passage 3 话题：西班牙度假的经历 词数：260词 难度：★★☆ 建议用时：6分钟 Last year I went on holiday to southern Spain with my best friends, Jenny and Alice. The Spanish people are very warm to visitors. Although I suggest you should know a few simple words in Spanish to communicate with local people, the Spanish people are willing to speak in English. When we arrived, we didn’t know where to find a hotel. I came to an old man and asked him for help politely. With his help, we got to a cheap but wonderful hotel, which even had a swimming pool. There we really enjoyed ourselves. This year, Jenny is going away with her parents to Greece, so it will be just Alice and me. Alice wants us to go on an adventure holiday in Africa. That means we have to go walking in the desert and sleep out in the open. She said it would be better than having a lazy holiday, because we would learn about the world around us and see some wild animals. I’m not sure whether I want to go to Africa. For me, a holiday means relaxing on a beach, not walking all the way. Alice said that we would see elephants and have some amazing experiences. I think she’s bored with lying in the sun all day. I have to make up my mind by next Monday so that she can buy plane tickets.

Passage 4 话题：生活中我们并不能事事都得偿所愿 词数：304词 难度：★★★ 建议用时：10分钟 Two years ago, what my 10-year-old son Peter wanted for Christmas was a Hess truck. I told it to my husband Joe, and we agreed to order it. Unluckily, we did not buy it at all. Joe thought I had bought it, and I thought he had. Well, never mind. It was only 9th December. I would just go online and get it. But it was not that simple. My heart dropped when I went on the Hess truck website and saw that the Hess trucks were sold out. I didn’t want to make Peter sad. Finally, I told myself that nothing is difficult for a man who will try. I found out that a shopping center was selling the Hess trucks, but they wouldn’t be available until a month later. Then I decided to buy the Hess truck on Amazon. When I saw it had the Hess trucks, I got excited. Then I noticed that the price was $144, much higher than the list price which was about $30. I decided to tell Peter the truth. Hearing my words, he started to cry. I hugged him for a long time. I said we were really sorry. I also told him something else that he had to learn sooner or later. 原创精品资源学科网独家享有版权，侵权必究！ 5 After a long hug, he stopped crying. Then Joe and I searched the Internet and started looking at other kinds of toy trucks. The next day at school, Peter’s teacher asked all the students to write about one thing they wanted for the holidays. Peter said that he wouldn’t get the Hess truck even though it was the only thing he wanted. But he added that it was OK because Mum had told him that sometimes we just can’t get what we want. ( )13.

You would probably go to an eye doctor who might give you glasses. For many people around the world, however, such a way isn’t that simple. The World Health Organization reports that glasses can help one billion people in the world. Yet places like Ghana have only one eye doctor every 8 million people. This makes glasses almost impossible to get. Joshua Silver, a teacher at Oxford University, however, may have solved the problem. 原创精品资源学科网独家享有版权，侵权必究！ 6 Mr Silver has developed liquid(液体)-filled glasses that users can adjust(调整) by themselves without seeing a doctor! The lenses(镜片) are filled with oil. Using a dial on the glasses, the user changes the amount of oil. This changes the strength(度数) of the lens. After the user finds the right strength, be then fixes the lens. Results show that among those who have tied the glasses, around 80% are satisfied. Mr Silver’s goal is for everyone who still needs glasses to have such glasses as soon as possible. With a little more effort, Mr Silver thinks that his goal might be achieved in the near future. ( )17. The underlined word “This” in the second paragraph means ________.

Passage 6 话题：减少食物浪费 词数：186词 难度：★★ 建议用时：4分钟 原创精品资源学科网独家享有版权，侵权必究！ 7 Many countries are dealing with food waste. What are they doing to stop it? China has been promoting（推广）a nationwide activity called “Clear Your Plate” sine 2013. In 2020, some restaurants are encouraging people to order food using “N-1”. “N” stands for the number of people who have dinner at a table. If there are 6 people at your table, you only order 5 dishes. In 2016, France passed a law that asks many stores not to throw away unsold food. It’s still safe to eat, the food must be given away to the poor; if not, it goes to farmers for use as animal feed. In 2019, the US said it encourages food companies to use the words “bet if used by” for date labeling（标注）. This helps shoppers better understand one thing. They don’t need to throw food out after the printed date passes if the food is stored correctly. In Japan, there are many food banks. People and stores can give unnecessary food to them and they will provide the food for those in need. ( )21. How many dishes should you order if there are eight people at the table in China? A．6.

And pet owners are now willing to spend more money on their pets than before. According to a report from Goumin.Com, Chinese people living in cities spent a total of 202.4 原创精品资源学科网独家享有版权，侵权必究！ 8 billion yuan on their pets in 2019. Most pet owners are people born after 1990. Most of them have incomes（收入）and are well educated. Pet owners in China are spending more money on pet food and clothing, according to a report from Euromonitor International. Miss Hou, 28, lives in the city of Chengdu. She spent 6,000 yuan on her two cats last year. “I bought cat food from the United States, New Zealand, Japan and Thailand,” Hou said. “If I have time, I also cook for them,” she said. “An aging society and fewer people having children are among the main reasons why more people are keeping pets,” said Liu Xiaoxia, CEO of Goumin.Com. “Keeping pets has met the emotional（感情的）needs of many people. Almost 60% of pet owners see their animal friends as their own children,” Liu said. Beating loneliness might be another reason. Many young people are leaving their hometowns to make a living in big cities. “They have a fear of great loneliness and have much pressure（压力）, as they have few friends and face a high cost of living. Keeping pets will help them feel relaxed,” the 2019 Chinese Pet Industry White Paper said. ( )25. According to Paragraph 2, most pet owners who ________ spent much money on their pets.

A．make people become kind B．help people make more friends C．let people have more children D．meet people’s emotional needs Passage 8 话题：成为宇航员的条件 词数：306词 难度：★★★ 建议用时：8分钟 原创精品资源学科网独家享有版权，侵权必究！ 9 Can anyone be an astronaut? Of course not. You don’t have to have a science degree but most astronauts do. Most of them are pilots too. Life in a spaceship is hard so you must have a healthy body and mind. You need to be easy-going, patient, and helpful to spend so much time in a small space with other people. What’s the training like? People have to train for a year to learn how to stay healthy and safe. They practice space walking and living in zero gravity (重力). They train in difficult conditions to learn how to solve problems and to work in a team. Everyday tasks like eating, washing and sleeping can be difficult on a spaceship. There is no running water so you have to wash with wet tissues: it’s hard to enjoy the dry food that astronauts have to eat. And to sleep you must cover your eyes because the sun rises every 90 minutes on the International Space Station. You also have to tie yourself to something so you don’t fly away! What health problems do astronauts have? Life in zero gravity causes changes to our bodies. Bones and muscles (肌肉) become thin and weak so you must do a lot of exercise in space to stay fit and to help the heart move blood around your body. Astronauts often get backache because you grow in space—up to 8 centimeters! It’s also common to have headaches and to feel sick, especially at the beginning. You must have vitamins to take the place of fresh fruit and vegetables. But you don’t have to put on sun cream because space suits protect your skin (皮肤). Are you still interested? ( )29. What is a must for an astronaut? A．A science degree. B．A pilot’s license. C．A healthy body and mind. D．Aweak character. ( )30. What must you do to prepare for a space trip? A．Experience zero gravity.

B．To help the heart work well and keep fit. 原创精品资源学科网独家享有版权，侵权必究！ 10 C．To avoid backache and grow much taller. D．To stop their skins from getting sunburned. ( )32. What is the text mainly about? A．What we need to know to become an astronaut. B．Why young people are interested in space trips? C．What problems astronauts must solve in space. D．Why we need to train hard before a space trip. 原创精品资源学科网独家享有版权，侵权必究！ 1 专项 3 阅读理解 答案解析 Passage 1 【答案】1.A 2.D 3.B 4.C 【导语】本文主要讲述了作者和他的母亲把自己的感受写在笔记本上，并交换阅读，以此来交 流和沟通的事情。 1.细节理解题。根据“'When I returned home at night, I saw all the pain, anger and disappointment on my mother's face”"可知，母亲脸上有痛苦，生气和失望，没有尴尬的表情。故选 A。 2.细节理解题。根据“After we finished writing, we exchanged our notebooks”可知，写完后他们交 换了笔记本。故选 D。 3.主旨大意题，根据“Finally, it felt like all the anger inside me went away from my body.
