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

II/ Read the passage. Then write True or False for each of the sentences below. (1.5pt)

In the UK we each use about two hundred steel food and drink cans every year. Steel cans are popular because they are convenient, easy to store and unbreakable. But when you have finished with a can what do you do with it? Do you throw it away and forget all about it? Probably! But behind the scenes there are people whose work is to make sure that the steel is never wasted. In fact, recycling or re-using steel cans is so successful that every day of the year more than five million cans start new lives in new steel products.

After you have thrown away your can, what happens? Well, first of all it is collected by the men who empty your dustbin each week and take to a tip, together with all the other household rubbish. Then the rubbish is sorted and the steel cans are taken separately to a special factory which turns old cans into high quality steel. It’s this steel that may well find its way back into your home in the form of knives and folks, garden equipment and, of course, food and drink cans.

So next time you open your fizzy drink, just remember where your can may have been!

The invention of the phonograph happened quite by accident. Thomas Edison moved to Menlo Park, New Jersy in 1876, where he established an industrial research laboratory. There, Edison was working on a carbon telephone transmitter to improve the existing Bell telephone system.
In that laboratory a year later, Edison invented the phonograph while he was trying to
improve a telegraph repeater. He attached a telephone diaphragm to the needle in the telegraph
repeater; in this way, he was able to reproduce a recording that could be played back. After he made some improvements to the machine, he tested it. He recited “Mary Had a Little Lamb” into the machine and played his voice back to a very surprised audience.
