项中，选出最佳选项。
A
The human brain can hold much more information than most computers. However, computers don't
forget information, and humans often do. No one remembers everything. Luckily we don't usually have to.
But everyone can improve their memory if they want to. Here are some suggestions.
Try to use new information at once. If you meet someone who says, “Hi! I'm Carlos.” Don't just
answ◆er, “Hello”. Repeat(重复) the person's name. Say, “Hello, Carlos.”
Break a big number into smaller parts. It's hard to memorize 109244153. But if you break it into three
parts—◆109，244 and 153. It becomes easier.
Always review information. If you bring what you've learned back to your mind, they become easier
to rem◆ember. For example, before you go to sleep, it's a good idea to read the new things you learned that
day.
Discuss with a friend. It is always easier to remember things through discussions. You can have a
discu◆ssion about what's right and what's wrong, and it will lead to the right answer.
Never tell yourself that you have a bad memory. Be confident! You can always do something to help
impro◆ve your memory. And everyone's memory can get better if they follow the right ways.
( )11. How many differences between the human brain and computers can we find in the passage?
A. Two. B. Three. C. Four. D. Five.
( )12. When we get new knowledge, we had better ___________.
A. use it immediately B. repeat it all the day
C. write it down and send it to someone D. have a talk with someone
( )13. How can people memorize a big number more easily according to the passage?
A. By keeping it in a computer. B. By breaking it into smaller parts.
C. By reading it again and again. D. By reviewing it before you sleep.
( )14. What is NOT the right way to help you improve your memory?
A. Having discussions with friends.
B. Reviewing your new knowledge in time.
C. Finding a quiet place to think the unknown question.
D. Being confident in your memory ability.
( )15. What does the sentence “Never tell yourself that you have a bad memory” in the last paragraph
mean?A. You should tell others about your bad memory.
B. You should believe in other people all the time.
C. You should ask others to improve their memory.
D. You should be confident in your memory ability.
B
Do you still remember the summer holiday last year? When you think back on it, you might think of
many of your happy times. But how do you store these things in your mind? By using your memory.
Memory is the ability to remember things. Memorizing happens in a special area in our brain. When
something happens, your brain records(记录) the important information and puts it in that area. That is what
we call “memory”.
Scientists say that there are two kinds of memory—shortterm memory and longterm memory. Your
shortterm memory can only last for a few seconds to a few minutes. But longterm memory is able to save
information for a long period of time. People usually remember with shortterm memory, and then forget
things quickly after they experience them. They learn about something one day, but forget half of it the next
day. A week later, they remember just a third of what they have learnt. So people forget things easily
without memorizing again and again.
Scientists agree that people remember things in different ways. Some remember things better with the
help of pictures. Others remember better when they take in the information by hearing it. But one thing is for
sure, if you remember things with different ways together, you can get a better result. For example, try
imaging pictures with English words, and at the same time listening to recordings of the words. Maybe
studying English won't be a difficult thing.
( )16. The underlined word “store” in Paragraph 1 means ________.
A. keep B. carry C. discuss D. imagine
( )17. What can we learn about the long-term memory from the passage?
A. Long-term memory is the most important way of memorizing.
B. Long-term memory lasts shorter than short-term memory.
C. Long-term memory can save information about one week.
D. People can get long-term memory by memorizing again and again.
( )18. According to the scientists, how can people remember things better?
A. By connecting sounds with pictures.
B. By taking in information with smell.
C. By connecting pictures with English words.
D. By remembering with the help of pictures and sounds.( )19. What is the passage mainly about?
A. Some different types of memory. B. Some difficulties in learning English.
C. Some interesting facts about memory. D. Some ways to improve memory.
( )20. In which section of the newspaper would you probably read this article?
A. Fashion. B. Sports. C. Science. D. Stories.

Dear Mary，
I'm glad to give you some advice on how to improve your memory.
First, before you remember something, you'd better spend some time understanding it.
Second, it's a good way to connect what you want to remember with what you have known. It
can help you remember things for a long time. What's more, you can try making a picture of itin your mind. It is very helpful. Finally, healthy food, enough sleep and exercise are also
important for improving your memory.
I hope my advice will help you. And you can write back to me if you have any problems.
Best wishes!
Yours,
Li Hua
