Scientists are still working on the 　35　.
　　As well as this tendency (趋势) to lose memories from the first three years, most people have 　36　 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 　37　 something or someone from years ago. It is also 　38　 for a smell or sound to bring back a feeling.

　　Do you have trouble remembering where you put your eraser Doing puzzles may help keep your mind sharp, but diet can make a big difference too.
　　According to many studies, some food and drinks may help to improve your memory. Why not try them Scientists have found that sufficient (足够的) amounts of vitamin B2 can improve your memory. It's found in common things like milk and dark green vegetables.
　　You can add a banana to 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 in memory.
　　Try a cup of tea. Not only does it keep your brain working right, it also helps to relax and fight against mental tiredness.
　　We know that eggs are full of vitamin B12, which helps to fight against brain shrinkage (收缩) that is bad for the memory.
To improve your intake of zinc (锌), you can eat more wholegrains. Wholegrains help your brain work well.
　　If you're really serious about improving your memory, don't forget to make time for a good breakfast. A study found breakfast helped people score better on memory tests. And when kids eat a morning meal, their exam scores improve. “You are what you eat.” A well-balanced diet is of course great for your body. What's more, junk food like hamburgers, chips and candies is bad for your health and memory. You should try to keep away from it.

　　When I was a little kid, my parents were poor, and we lived in a camp in the countryside in Portland. Dad had two jobs and Mum was in bad health.
　　Our clothes were always old and our food was usually cheap and simple. However, we were always satisfied with our hot chocolate, which was made in a traditional way handed down from my grandmother to my mother.
　　At that time, there was no store to buy anything we needed. We just had powdered cocoa (可可粉) in our camp. Mum would set an old coffee pot at the side of the fire and slowly warm the milk, adding chocolate and sugar, and stirring (搅拌) until they became thick and rich brown. The wonderful smell of chocolate filled the camp.
　　More than once, I could remember people that passed by stepped into our camp to enjoy Mother's work. And Mum always gave these strangers some hot chocolate to enjoy.
　　Once we had to stay in our tent for days because of a terrible rainstorm. Every morning I was woken up by the sweet smell of Mum's hot chocolate.
　　Now, many years have passed. I have told my family a lot about Mum, and it seems that nothing brings back those warm memories better than sitting around the fire at night and tasting sweet hot chocolate.

　　“What's the name of the man living next door I can't remember it right now.” Have you ever heard your grandparents ask questions like this Usually, we think old people's memories become bad because their brains can't work quickly. But a team of German scientists has a different idea.
　　“The human brain works slower in old age，” said scientist Michael Ramscar, “but only because it has kept much more information over time.”
　　The findings are a result of many computer simulations (模拟) of learning and memory. Scientists let the computers read words and learn new things each day. When the computer “reads” only so much, its result in memory tests is the same as that of a young man. But if the computer learns much more than that, its result is the same as that of an older man. It is slower because more information makes the computer's database (数据库) grow and the computer has more data to work with—it takes time. This is the same as old people.
　　Think about this. A man knows two persons' birthdays. Another man knows the birthdays of 2，000 people, but can only match the right man to the right birthday nine times out of ten. Can you say that the first man has a better memory than the second one The fact is that “The larger the library you have in your head, the longer it usually takes to find a word，” Benedict Carey, a science reporter for the New York Times, wrote in a report about the study.
62．What does the writer use the question at the beginning for
A．Making readers think of their friends.
B．Saying that many people have bad memories.
C．Making readers interested in the passage.
D．Showing why older people like asking questions.
63．Why do old people forget other people's names easily
A．Because they have a very poor memory.
B．Because they are too old to remember things.
C．Because there is something wrong with their brains.
D．Because there is too much information in their brains.
64．How did the scientists do the study
A．By asking old people questions.
B．By reading books and some useful reports.
C．By following the lives of a group of old people.
D．By using computers to simulate man's learning and memory.
65．What does the passage mainly talk about
A．Is it better to be old or young
B．How can man use their brains
C．Do old people have poor memories
D．What are scientists' new findings on brains
D
　　New research coming out of Tohoku University suggests that wasabi is good for the ability to remember. Wasabi, a spicy green paste, is eaten in small amounts in sushi and along with other Japanese dishes. It is made from the wasabi plant, a member of the mustard family.
　　A recent study tested people between the ages of sixty and eighty. Some of the test subjects took a wasabi extract (提取物) nightly before going to bed. The other test subjects were given a placebo. After three months, the people who took the wasabi extract had significantly better results in short-term and long-term memory tests. The placebo-takers did not show any improvement. Wasabi was already known to contain an antioxidant (抗氧化剂) and anti-inflammatory (抗炎物) called 6-MSITC that is rare in other plants. The researchers think that 6-MSITC might affect the hippocampus (海马体) in our brains, the area that is responsible for memory function. They will continue researching with the hope that wasabi can help people that are experiencing dementia (痴呆)．
　　This new research seems to be good news for sushi-eaters, but most wasabi that is served in Japan is not real wasabi. Instead, it is white horseradish (辣根), a plant whose root has a strong taste like wasabi plant. Often it has been dyed green so people are likely to regard it as real wasabi, not only from taste but also from colour. Real wasabi is difficult to grow and, as a result, is very expensive. It also needs to be grated and served fresh immediately before being eaten.
66．According to paragraph 1, what is “wasabi”？
A．It is a member of the mustard family.
B．It is a green plant with a spicy taste.
C．It is an eatable paste with a strong taste.
D．It is a kind of Japanese dish.
67．What does the underlined word “placebo” in paragraph 2 probably mean
A．Replacement. B．Power.
C．Treatment. D．Service.
68．What is the main focus of the researchers' continued research on wasabi
A．To discover new antioxidants in wasabi.
B．To study the 6-MSITC found in wasabi.
C．To check the possible benefits of wasabi for people with dementia.
D．To understand the structure of the hippocampus in people's brain.
69．Why most wasabi served in Japan is not real wasabi
A．Real wasabi is easy to grow but has a different taste.
B．Real wasabi is difficult to grow and very expensive.
C．People prefer the taste of white horseradish to real wasabi.
D．White horseradish is easier to dye green than real wasabi.
70．What is the purpose of the passage
A．To introduce the health benefits of sushi.
B．To introduce wasabi: a memory-improving item.
C．To tell us the science behind Japanese dish.
D．To tell us the truth about wasabi in Japan.
第二节　阅读表达(共5小题；每小题2分，满分10分)
　　阅读下面短文，简略回答问题。
　　A recent study on humans suggests Western high-fat, high-sugar “junk food” can quickly break your brain's appetite (胃口) control.
　　The researchers let the young enjoy the delicious cookies, tasty ice creams and similarly rich foods for a week long. They did the research in Australia. They found young and healthy volunteers scored worse on memory tests. At the same time, they also had a greater wish for junk food.
　　The findings suggest something is wrong in the hippocampus. What is hippocampus It is an area of the brain. It can help memory and control appetite. When we are full, the hippocampus is thought to make our memories of delicious food less active, cutting down our appetite. When there is something wrong in this area, this control can be badly broken.
　　Over the years, further research on the mice has found the role of the hippocampus is easily affected by “junk food”. But this has only recently been found in young and healthy humans.
　　In 2017, after a week of Western-style breakfasts, researchers found volunteers performed worse on learning and memory tests. They clearly depend on the hippocampus．
　　Now, in this latest study the team has found that not only do such high-fat, high-sugar foods impair (损害) memory in humans, but they also appear to directly affect our ability to control our appetite.
71．How did the young men behave after eating junk food for a week

72．What is “hippocampus”

73．What role does “hippocampus” play in our body

74．What can affect our ability to control our appetite according to the passage

75．What small change can you make to your daily diet to stay away from the bad influence of junk food

　　Do you want to improve your memory Here is some advice for you.
　　First, you should use your brain as much as possible. It is especially important to try to learn something new. If you work in an office, learn to dance. If you are a dancer, learn to deal with a computer. These activities help exercise your brain. Second, repeat important information out loud. The action of saying and hearing also makes the information easier to memorize. Third, pay attention to one thing at a time. Don't try to memorize everything that catches your attention. Another useful way is to relax. It's impossible to remember things if you are nervous.

81．One possible version：
Dear Mike，
　　During our English Week, we had a debate on “Is memory the key factor in English learning？” I'm writing to share my unforgettable experience with you.
　　Some students thought a good memory helps memorize numerous words, which is essential for English learning. However, others believed learning methods are more important. They said proper ways like watching English movies and reading English stories can improve English comprehensively.
　　In my opinion, both memory and methods are crucial. Memory helps us store knowledge, while methods guide us to use it effectively. Only by combining them can we truly master English.
　　I had a good time in the English Week. What do you think about it I'm looking forward to hearing from you.
Best regards，
Li Hua
