B Memory is the ability to store and recall information.It has two main kinds:short-term memory and long-term memory.Short-term memory only keeps things for a few minutes,like a new phone number you just heard.Long-term memory can store information for months or even years,such as your childhood stories and basic knowledge. Here are simple ways to turn short-term memory into long-term memory.First,review knowledge regularly.Don't wait until exams to remember everything.Second,use imagination:make funny pictures or short stories for difficult words.Third,divide information into small groups.It's much easier to remember small parts than a whole long passage.Besides,enough sleep and daily exercise also help your brain work better and boost your memory. Good memory is not a gift only for clever people.It comes from right methods and constant practice. ()5.How many types of memory are mentioned in the passage? A.One. B.Two. C.Three. D.Four.

D.How to use imagination in English study C 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 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)called6-MSITC that is rare in other plants.The researchers think that 6-MSITC might affect the hippocampus (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 () 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,a plant whose root has a strong taste like the 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（磨碎)and served immediately before being eaten.. （）9.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. (10.What does the underlined word "placebo"in Paragraph 2 probably mean? A.Replacement.B.Power. C.Treatment. D.Service. ()11.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. ·27· ()12.What is the best title for the passage? A.The Health Benefits of Sushi B.Wasabi:A Memory-improving Item C.The Science behind Japanese Dishes D.The Truth about Wasabi in Japan D Do you know the five main senses we have?They are touch,taste,sight,smell and hearing. They are controlled by different parts of our brains.So we call the brain our built-in "BeiDou".Brains help our bodies work smoothly.Try this:close your eyes and touch your nose.It's easy,right?That's because our brains can receive messages about where our body parts are.We can also stand on one leg without falling down.If we lose our balance,our brains will give us orders to fix it. Brains are also life-saving heroes.Tests show that people see spider pictures faster than flowers. Some researchers also found that people react ()to loud noises faster than to a friend's voice. Scientists aren't completely sure about the reasons.Some suggest that this skill might come from ancient times.Our ancestors were often faced with predators.So they had to protect themselves from dangerous animals like spiders and tigers,or they would lose their lives.Until today,we still jump at sudden noises or shadows(影子)in dark rooms. Here is more about the brain.Can you imagine seeing colors when you hear music,or tasting candy when you see the sunshine?It's called sense mixing.Scientists think this happens when different senses intermingle ()Another fact is that temperature sometimes influences our senses. Some people can feel storms coming through with knee pain.So we often joke that we're "human weather apps'”.Also,our brains are able to make adjustments(调整）to some senses.If someone can't see well,his hearing or touch might become stronger. Though scientists have done much research on the brain,there's still a lot to do.Have you ever wondered why some people are better at sports?What's the secret to improving memory?Then it's time for you to start your discovery journey. ()13.What do the two examples in the first paragraph show? A.Human brains are different. B.Brains help our bodies work well. C.People have many living habits. D.Humans can touch their noses easily. ()14.Which animal in the following is probably a "predator"? A.A lion. B.A sheep. C.A deer. D.A butterfly. ()15.According to Paragraph 3,what might happen if your senses mix? A.You can tie your shoes without looking. B.You taste sweetness when seeing a rainbow. C.You jump when someone shouts suddenly. D.You feel pain in your knees before the rain comes. ·28· ()16.What is the writing purpose of the last paragraph? A.To improve people's memory. B.To show the value of our brains. C.To encourage brain studies. D.To admire scientists'efforts. 第二节阅读短文，从方框内所给的选项中选出可以填入空白处的最佳选项，其中有一个多余 的选项。 Most of us know that our brains become smaller in size as we get older,but did you know that diet and lifestyle have an effect on how well our brains work? Research shows that eating lots of fruit,vegetables and proteins（a蛋白质)improves memory. 17 Eating oily fish or dark chocolate (with over 70%cocoa)and taking Vitamin D3 can also help make your memory stronger. 18 A 2011 study showed that regular exercise actually increases brain size.Another study found that exercise improved memory in some older people.Surprisingly,it found that one single training period had the same effect on memory as regular,long exercise period! One study found that eight weeks of short,daily meditation (improved memory.Other ways to relax can also improve our short-term memory.Try taking 5~10 minutes of your day to meditate or listen to music.19 Experts say that age reduces our ability to learn,but sleep can help.For your brain to work well, 7~9 hours of sleep is necessary.A 2019 study found that students learned things better before and after a short sleep！ 20 Try to memorize information like phone numbers and addresses rather than putting the information in your phone.You could also learn a language or do brain training like crosswords 游戏). A.Or even just take a shower! B.Use your phone to help you memorize things. C.The role of exercise is really important too. D.Try to avoid sugary foods such as cakes and milk chocolate.
