A 教材同步单元练习 一、阅读理解 A篇 Your memory plays an important role in your life.It helps you remember who you are, where you live,what you have learnt and what you plan to do in the future. So,how can you improve your memory? First,it is helpful to live a mentally active life.Make a point of trying new things.For example,you will exercise your brain if you learn to play a new instrument or learn a foreign language.You can also improve your memory with brain games,such as crosswords,word games and maths puzzles.Techniques like memory linking also work your brain and improve your memory.In memory linking,you make mental connections to help you remember things.For example,you can make up a story to link items in a list so that you will remember them.You will be exercising your brain as well as improving your memory! Second,if you live a healthy life,your memory will work better.Healthy eating habits are especially important,and a healthy diet helps maintain a good memory.Research shows that eating green vegetables,nuts,berries,and oily fish can improve your ability to remember things.What's more,regular physical exercise and getting enough sleep also help improve your memory. Last but not least,it is important to get plenty of rest.Unless you take time to relax, your brain will find it hard to remember things.Besides,if you get too stressed or worried,your memory will become less sharp. Everyone has moments of forgetfulness and memory tends to decline with age. Therefore,it is quite normal for people to experience memory loss as they get older. However,you can maintain and even improve your memory if you exercise your brain, live a healthy life and make time to relax! ()1 According to the passage,which of the following is NOT a way to improve memory? A.Learning a new language. B.Playing maths puzzles. C.Eating red meat every day D.Getting enough sleep. ()2 What does the phrase "memory linking"mean in the passage? A.Remembering things by writing them down. B.Connecting things in your mind to help remember. C.Using a special machine to improve memory. D.Repeating words many times. ()3 What can we infer from the last paragraph? A.Memory loss is not normal for old people. B.Old people cannot improve their memory at all. C.Memory can be improved even as we age. D.Only young people have good memory. ()4 What is the best title for this passage? A.The Importance of Memory B.How to Improve Your Memory C.Why Memory Declines with Age D.Healthy Eating and Memory B篇 Have you ever forgotten where you put your keys or what you wanted to say?Don't worry-it happens to everyone.But some people seem to have super memories.How do they do it?Scientists have found that using a method called "the memory palace"can help you remember much more. The memory palace is an ancient technique.You imagine a place you know well,like your house.Then you put the things you want to remember into different rooms.For example,if you need to remember a shopping list,you can picture a giant apple in the living room,a bottle of milk on the bed,and a loaf of bread in the bathroom.When you need to recall the list,you just walk through your imaginary house and "see"the items. Why does this work?Our brains are very good at remembering places.By connecting new information with a familiar place,we create strong memories.To use this method well,you should make the scenes funny or strange.The sillier the picture,the easier you will remember it. Some memory champions use this technique to remember hundreds of numbers or a whole deck of cards.They practice for hours every day.But you don't need to be a champion to benefit.Even a simple memory palace can help you with your studies.Try it next time you have to remember a list of vocabulary words! ()1 What is the main idea of the passage? A.Everyone has a super memory. B.The memory palace is a useful way to remember things. C.We should practice memory every day. D.Scientists study how memories are formed. ()2 How does the memory palace work? A.You write down information on paper. B.You connect information with a familiar place. C.You repeat information many times. D.You use a computer program to help. ()3 What kind of pictures are best for the memory palace? A.Normal and realistic ones. B.Funny and strange ones. C.Beautiful and colorful ones D.Simple and clear ones. ()4 What can we learn from the last paragraph? A.Only champions can use the memory palace. B.The memory palace is too difficult for students. C.Even ordinary people can use this method to study D.You need to practice for hours to benefit ()5 What is the author's attitude towards the memory palace? A.Doubtful. B.Negative. C.Supportive. D.Unclear. 二、完形填空 Do you have trouble remembering English words?I used to,until I found a great way. Here is my story. Last term,I always got low marks in English tests.My teacher said,"You need to change your 1.of learning words."She told me to try using word cards.I wrote new words on small cards,with the word on one side and the Chinese meaning on the other.Every morning,I 2.the cards in my pocket and looked at them on the bus.At first,it was hard,but I kept 3. After a few weeks,I found I could remember more words.But I still forgot some words quickly.Then my friend Tom 4. _me a new method-the "memory palace".He said,"Imagine your room.Put each new word into a different place.For example,the word 'abandon'can be in your desk."I tried it and it 5.really well. Now I have a 6. memory than before.I can remember 50 new words in a day. More importantly,I 7. enjoy learning English.My teacher was surprised at my progress.She asked me to share my 8.with the class I believe that 9. you find the right way,you can improve your memory too. Don't give up!And remember,practice 10. perfect. A.plan B.way C.habit D.time A.put B.threw C.found D.lost A.practicing B.to practice C.practice D.practiced A.taught B.asked C.showed D.told A.worked B.worked out C.grew D.looked A.good B.better C.best D.well A.even B.still C.never D.hardly A.ideas B.stories C.experience D.mistakes A.if B.unless C.because D.though A.makes B.is making C.made D.will make 三、阅读短文回答问题 Do you know why we forget things?Scientists call the process of forgetting "the forgetting curve".It was first studied by a German psychologist named Hermann Ebbinghaus in the 1880s.He did experiments on himself to test how memory works. Ebbinghaus found that people forget information very quickly at first.For example,if you learn something new,you might forget 50%of it within an hour,70%within 24 hours,and 90%within a week.But there is good news:if you review the information at the right time,you can remember it much longer.This is called "spaced repetition". How can you use spaced repetition?Here is a simple plan:review new words or facts after 1 day,then after 3 days,then after 1 week,then after 2 weeks,and so on.Each time you review,the memory becomes stronger.Many language learning apps,like Anki and Quizlet,use this idea. Another important finding is that sleeping helps memory.When you sleep,your brain organizes and stores what you learned during the day.So getting enough sleep is not just for rest-it is also for remembering. 1.Who first studied the forgetting curve? 2.How much information might you forget within 24 hours? 3.What is the name of the method to review at the right time? 4.According to the passage,what can help you remember better besides reviewing? 5.Do you think the forgetting curve is useful for students?Why or why not? 四、短文填空 用方框中所给单词的适当形式填空，使短文完整正确。（每个单词限用一次，每空限填一个单 词。) able,achieve,active,connect,improve,keep,mind,regular,relax,sharp,train,way Do you want to have a better memory?Here are some tips.
