Read the following passage and choose the correct answer to each questions.

Your mind's ability to bring back experiences you have had is your memory. There are two kind of remembering, recall and recognition. For instance, you may not be able to recall the poem you read yesterday in class, but if you see it again, you will know it instantly because you recognise it.

Some few people have "total recall", often spoken of as photographic memory. A person with total recall can recite a whole page of a book he has read only once, or play a musical composition after hearing it once. This is very unusual, however, and most people have difficulty in remembering even the names they heard the day before. This is not because most people lack the ability to remember, but because they had not paid much attention to what they heard. They felt no personal reasons to remember. Having a personal reason for remembering is one of the most important factors in a good memory.

When you have a strong reason for remembering, concentrate as you read or listen, and try to connect the new information to things you already know. A detail is easy to remember when it fits into a whole that make sense. If you understand the entire history lesson before you try to remember any particular dates, your memory may surprise you.

1. One way to improve your memory is __________.

A. to ask other people to repeat something again and again

B. to have a camera with you all the time

C. to concentrate on what you listen or read

D. to learn everything you read or hear by heart

2. This article as a whole tells us about __________.

A. people who can remember whole pages

B. people who can’t remember names

C. your memory and how you may improve it

D. recognition as one way to remember things

3. A person with photographic memory __________.

A. can only remember things if he looks at a photograph

B. can remember every detail of what he sees or hears

C. can be found in mental hospitals

D. brings his camera everywhere he goes

4. Which of the following is NOT true according to the passage?

A. Most people lack the ability to remember.

B. Recognition and recall are the two kinds of memory.

C. Your memory is your ability to bring back experiences you had.

D. A person can remember things better if he has a strong reason for doing it.

5. While not directly stated, it may inferred from the article that __________.

A. details are more easily remembered than the whole

B. recall and recognition are the same

C. if one tries hard enough, he can remember as well as another

D. wanting to do a thing is very important to being able to do it

If it were not for fossils, we would have no way of knowing about the animals that once roamed the earth or that once crawled on the bottom of the ancient seas. In fact, we would not even know for sure that there were once seas in some regions if it were not for the many fossils of sea animals that we find there.

You can look at some fossils and see for yourself the shape of the ancient animals. Even if you collect only bits of one kind of fossil, you may still be able to tell what it looked like. Making sense out of fossil bits is a little like working a jigsaw puzzle. Sometimes you will lose pieces, but you can still recognize the picture and even use your imagination to fill in missing details. The habits of ancient sea animals are not so easy to determine. Therefore, scientists study the structure and the habits of similar living animals to learn what the ancient ones must have been like. There are some things, however, that neither the study of fossils nor the study of living animals can tell us. For example, no one knows what colour most ancient sea animals were. Also, since the soft parts disappeared soon after death, many details of their internal structure are unknown. So the pictures of ancient sea creatures (as well as dinosaurs!) are what scientists think the animals looked like. Reconstructing the life of an ancient sea animal on the basis of fossil evidence and the characteristics of similar living animals is a little like relying on circumstantial evidence in court.

1. This passage is mainly about animals that __________.

A. have very tough hides

B. once lived on the earth

C. inhabit the seas of today

D. are becoming extinct

2. With the help of fossils we can __________.

A. reconstruct life of the past

B. predict the future

C. explain the changes of the seasons

D. save some species of animals from extinction

3. Many details of ancient animals are lacking because __________.

A. many species have not been found
