The first group can be fruits, apples and bananas. The second group can be school things, pens and notebooks. And milk is on its zone. Now you just need to remember the groups and the things in them. This method makes for remembering much easier because your brain likes organized information. You can use this trick for shopping, and IT is also very helpful for studying.

One method is to test memory. Scientists in japan showed a group of college students and a group of five year old champs, the numbers one to nine in different places on a computer screen. The test was to see if the groups could remember the position of the numbers in the correct order each time the chimps were faster than the students. Why were the chips special? In a way? Did anyone assist them? know. But the chance probably had an important advantage. They were Young. As both humans and animals get older, their memory gets worse.

Her _38_ and I won't do it like that.” The teacher went on to tell Mrs.Black not to be so _39_ and in fact, her daughter still did well in school.“She is very sweet and cute,” the teacher said.

Interestingly, young children are often able to remember certain things from their first two _43_ of life.But for reasons which are not completely understood, they generally lose this _44_ as they get older.Do those earliest memories disappear for some reason? Nobody is sure.Scientists are still working on the _45_. As well as this tendency (趋势) to lose memories from the first three years, most people have _46_ memories up to the age of eight than of other periods in their lives.Sometimes a picture or a piece of music can make you _47_ something or someone from years ago.It is also _48_ for a smell or sound to bring back a feeling.We still do not know exactly how the human mind _49_ information.However, we know that people are more likely to _50_ lasting memories if they often memorize childhood experiences.Based on this, scientists will continue to work on the subject. 41.

Do you often forget where you put your erasers? According to many studies, some foods are good for your memory.Why not try them? Scientists have found that vitamin B2 can improve your memory.It's found in common things like milk and dark green vegetables. You can have a banana for your breakfast.It will be easier for you to focus on what the teachers say. Studies have shown that eating fish once a week produces a 10 percent slower decline (衰退) in memory. We know that eggs are full of vitamin B12.It helps to fight against brain shrinkage (收缩). If you're really serious about your memory, don't forget to make time for a good breakfast.A study found breakfast helped people score better on memory tests.“You are what you eat.” A healthy eating habit is great for your bodies.What's more, junk foods like cola, fried chips and candies are bad for your health and memory.You should try to keep away from them. 56. If Jenny feels sleepy, which food can help her focus on the morning math class? A.Bananas. B.Milk or vegetables. C.Fried chips. D.Fish or eggs. 57. What can we learn from the last paragraph?

A.diary B.dictionary C.newspaper D.storybook B Many students have problems with vocabulary when preparing for tests. Here is some advice on how to memorize new words. Repeated encounters (反复遇见). The usual way of memorizing new words is through repeating them while they're still in your mind. However, it doesn't seem to be useful. But the following way is helpful: repeated encounters. We can memorize words more easily if we've met them at least seven times in our reading. So, read English magazines and newspapers from time to time. Spacing (间隔) and review. It's necessary to make a plan of your memory work over a period of time. You'd better memorize words day by day instead of doing it in a single day. Use it or lose it. Putting words to use in interesting ways helps add them to your long term memory. In a study of vocabulary learning, students who made up their own sentences with new words memorized them better than those who learned the words separately and silently. Mix it up. Try watching videos (视频) from English speaking countries and copying the way they speak. You can even upload (上传) your own videos and try becoming a star yourself. 59. What is the usual way of memorizing new words according to the text? A.Making word cards. B.Reading them aloud. C.Repeating them while they are in your mind. D.Reviewing them again and again. 60. What kind of students can memorize the words better? A.Students who have no plans. B.Students who have enough sleep. C.Students who learn the words separately and silently. D.Students who make up their own sentences with new words. 61. What is the writer mainly trying to do in the text? A.Tell us to read more English magazines. B.Show us some good ways to memorize new words. C.Ask us to watch videos from English speaking countries. D.Teach us to make a plan of our memory work. C Not long ago, a photo of the football players in my college showed up on my phone as a “memory”, which was kept through the digital memory (数字记忆). I was surprised to see the photo at first and sweet memories flashed into my mind. In the photo, the players from the football team hugged together in excitement after they won the game. At that time, I took a photo of them with my phone. It recorded the friendship and the happiness. Then, I fell into the habit of taking photos of everything. More and more photos filled my phone so I almost forgot this photo. Thanks to the digital memory, I could enjoy the happy time again. People needed to make an effort to record things in the past. But now we can do something like that easily through the digital memory. We put what we want to remember into our smartphones. Most of the photos that I have kept on my phones—and in the cloud now—bring happy memories back to me. However, not all the digital memories are happy. Some are sad. When I see the photos of my lost pet, I am worried. Because they make me recall something I want to forget. Usually, digital memories are sent to me non stop and without any human like feelings. That drives me crazy. It's hard to say clearly when the digital memory started madly. These digital memories, whether happy or sad, break into our lives. In my job as a reporter, I have spent the past five years taking different photos. They will always be there, whatever. 62. How did the writer feel when he saw the photo at first? A.Excited. B.Afraid. C.Bored. D.Surprised. 63. What does the underlined word “It” in Paragraph 2 refer to (指代)? A.The college. B.The photo taken by the writer. C.The football team. D.The game held long ago. 64. How do people record things easily now? A.By using smartphones. B.By valuing time. C.By creating memories with feelings. D.By developing good habits. 65.(高阶思维 推理判断) Why does the writer mention his lost pet? A.To hide some sadness in his life. B.To help people run away from the past. C.To show his dislike of some digital memories. D.To explain the digital memory is very easy to use. D Are you good at remembering what you've learned at school? Is it an easy process for all people? No one's memory is perfect. Even the smartest people forget things. This does not mean a person has a bad memory. It means he is not using his mind to his advantages. The brain has short term memory and long term memory. The skill for remembering is moving information from short term memory to long term memory. No one knows exactly how this happens. But one thing is for sure—practising, or making repetition of information, is one of the most popular methods of remembering. And scientists say that long term memory will never fill up completely with memories in one's lifetime. Then why do we forget things? Forgetting things that are not important helps our brain to remember things that are important. Our brain is always “cleaning out” useless information to make room for something more useful. If you are interested in improving your memory, there are lots of simple things you can do, like eating healthily, sleeping well and exercising daily. Besides, it's also important to challenge your brain. You can play mind games, learn a musical instrument or study a new language. All you need to do is keep your brain healthy and active. 66. How does the writer begin the passage? A.By listing numbers. B.By comparing facts. C.By asking questions. D.By giving examples. 67. What is one of the most popular ways to remember information according to the passage? A.Listening or writing. B.Practising or asking. C.Listening or speaking. D.Practising or repeating. 68.(高阶思维 主旨大意) The last paragraph mainly talks about _. A.the ways to eat healthily B.the ways to improve our memory C.the reasons for playing mind games D.the reasons for studying a new language E New research from Tohoku University shows that wasabi (芥末) is good for people's memory. Wasabi is something that people usually eat in Japanese dishes. It is made from the wasabi plant, and has always become popular on Japanese menus. For further information, a recent study tested people between the ages of sixty and eighty. Some of them took a wasabi extract (提取物) every night before going to bed, while the other testers didn't. After three months, the people who took the wasabi extract did much better in short term and long term memory tests, with scores jumping an average of 18%. However, the other people did not show any improvement. Scientists already know that wasabi has something different called 6 MSITC. It is infrequent in other plants. The researchers think that 6 MSITC might do good to the hippocampus, the area that works for memory. Scientists say they will do more research, hoping to help people with memory problems. Wasabi not only improves the taste of dishes and people's memory, but 6 MSITC in wasabi can also help to keep us away from getting ill and offer many other good things to our health as well. The new research seems to be good news for sushi eaters. However, most wasabi in Japan is not real wasabi. Real wasabi is difficult to grow. The plant takes nearly two years to grow up and needs strict temperature, proper sunlight etc., and, as a result, wasabi is very expensive. 69. Which country is wasabi popular in? A.China. B.Japan. C.Canada. D.America. 70. What is Paragraph 2 mainly about? A.Who took part in the test. B.How long the research lasted. C.Why people took the test. D.How scientists carried out the study. 71. What does the underlined word “infrequent” in Paragraph 3 most probably mean? A.Unusual to see. B.Easy to find. C.Cheap to extract. D.Expensive to buy. 72.(新考法 后续推断)What will the writer most probably talk about next? A.The way people eat wasabi in Japan. B.The reason why wasabi is hard to get. C.The places where real wasabi plants grow. D.The health problems that wasabi can solve. 阅读下面短文,并用英语回答问题(请注意每小题的词数要求)。 F Last winter, I found an old wooden box in our attic (阁楼).It was dusty, with “Mom's Treasures” written on it in faded(褪色的) ink.Curious, I opened it and saw some yellowed letters tied with a red ribbon(丝带).They were from my mom to my grandma, written when Mom was my age. One letter caught my eye.“Dear Mom,” it began, “I failed my math test today, but you still hugged me and made my favorite dumplings.I'll try harder next time.” Reading this, I smiled— Mom always made dumplings for me when I was upset too.Another letter said,“Thanks for sitting with me by the window.Watching the snow together made everything better.” I ran downstairs with the box.“Mom, look at what I found!” I said.She laughed,and we spent the evening reading the letters together.I realized how much love was hidden in those simple moments— like _.That day, I learned that life's warmth isn't in big things, but in the quiet care we share.Now, I treasure every hug and every bowl of dumplings even more. 73. What did the writer find in the attic? (不超过5个词) _ 74. Why did the writer smile while reading the letters? (不超过10个词) _ 75. What would the writer say in the blank in the last paragraph?

Yours, Li Hua 听力材料及答案 一、1. M: Jane, don't forget to take your umbrella to school today. W: I've already got it here. Thanks, Dad. 2. M: Sorry, I forgot to bring your dictionary. W: That's OK, John. You can give it back to me tomorrow. 3. M:What's wrong, Lily? You look sad. W:I'm so upset.I forgot it was Amy's birthday yesterday. 4. M:Don't forget to buy some milk after school. W:I know.I'll write a note and put it in my pocket. 5. W:Why do you always read the text again and again? M:Repeating is a good way to make information enter my long term memory.It is helpful for my study. 二、Text 1 M:I have a history test tomorrow, but I can't remember all the dates. W:I have an idea.You can try to make a story with the dates.It's a good way to help you remember. M:Make a story? How? W:For example, if you need to remember the year 1840, you can imagine a story about “1 old man with 8 cats and 40 fish”.Making a picture in your mind helps too. M:Wow, that sounds fun! I'll try it. Text 2 M:Morning, Jenny.Sorry I forgot your birthday yesterday. W:Oh, that's OK, Billy.Tom came to celebrate my birthday.But you're forgetting quite a lot these days.Is everything OK? M:Yes, fine, thanks.I don't know why I am so forgetful. W:Maybe you're too busy.Can I help you with anything? M:Thanks.You are a good friend… Oh no! I left my homework at home! I need to go back!

M:Oh, no.I thought it was 9:30. W:Oh Billy, you really should go to that lecture on time! 三、 W:It can be hard to remember a long list of things, right? Here is a simple trick to help you.The trick is to put the things into small groups.For example, imagine you need to go to the supermarket to buy apples, pens, milk, notebooks, and bananas.Don't try to remember them all at once.Instead, you can make three groups.The first group can be “fruits”:apples and bananas.The second group can be “school things”:pens and notebooks.And milk is on its own.Now you just need to remember the groups and the things in them.This method makes remembering much easier because your brain likes organized information.You can use this trick for shopping, and it is also very helpful for studying. 四、 There are a few ways to test how smart animals are.One method is to test memory.Scientists in Japan showed a group of college students and a group of five year old chimps the numbers one to nine in different places on a computer screen.The test was to see if the groups could remember the position of the numbers in the correct order.Each time the chimps were faster than the students.Why?
