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.

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

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

A. people who can remember whole pages

B. people who can’t remember names

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

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.

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is basic human right. But acid rain, industrial pollution and garbage have made many sources of water undrinkable. Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. But they are being destroyed by the massive volumes of industrial effluent which pours into the lake everyday. Even where law existed, the government did not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world’s water surface. But it is the dumping ground for 50% of all marine pollution. Almost 16 countries regularly throw industrial wastes a few miles off shore.

Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect this precious source. We should do something now.

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is basic human right. But acid rain, industrial pollution and garbage have made many sources of water undrinkable. Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. But they are being destroyed by the massive volumes of industrial effluent which pours into the lake everyday. Even where law existed, the government did not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world’s water surface. But it is the dumping ground for 50% of all marine pollution. Almost 16 countries regularly throw industrial wastes a few miles off shore.

Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect this precious source. We should do something now.
