Man has a big brain. He can think, learn and speak. Scientists thought that men are different from animals because they can think and learn. They know now that dogs, cats and birds can learn too. They are beginning to understand that. They make noises when they are afraid, or angry or unhappy. Apes(猿) can understand some things more quickly than human, one or two of them have learnt a few words. But they can not join words to make sentences. They can not think like us because they have no language. Language is a wonderful thing. Man has been able to build a modern world because he has language. Every child can speak his own language very well when he is four or five, —but no animal learns to speak. How do children learn it ? Scientists do not really know. What happens inside our body when we speak? They do not know. They only know that man can speak because he has a brain.

Man still has a lot to learn about the most powerful and complex part of his body — the brain.

It may be surprising to learn that it isn’t age that makes you lose your memory. The reason could be that you have a "lazy" memory, not an old one. Like your body your memory improves with exercise. Once given plenty of exercise, the brain keeps its power. Before discussing how to improve the memory, let’s look at how the brain works. There are two sides to the brain, the left and the right. The right side deals with the senses (what we see, hear, feel and smell). It's the creative and imaginative side. The left side is concerned with logic. It analyzes information and puts it in order.

Some recent research suggests that we remember everything that happens to us. The problem most of us has is recalling events. Most forgetting takes place immediately after learning. An hour after learning something new, more than 50% has been forgotten. After a month, 80% has been forgotten, and so on.

This shows revision is very important. If you revise new material you have learnt, you remember much more. So it's of vital importance to revise newly learned material often, and have frequent breaks. We best remember what we learn at the beginning of a learning period and at the point where we stop. After the break, revise what was learned before the break and then continue learning the new material. These breaks should happen every 20 or 45 minutes.

Other experiments have shown the brain needs time to "digest" what has been learned. The time necessary for this is 5 to 10 minutes. After the break, the memory will have absorbed what it has just learned, and more will be remembered. During this period it is important to exercise the right side of the brain, because the left side is used during the learning period. Therefore you should relax. Listening to music, breathing in fresh air, and looking at a picture are all ways of using the other side of the brain. So when you are studying alone, make a plan which shows when to have breaks and to revise newly learned material immediately before you begin studying again. If you do in this way, your memory will improve.

1.According to the text, you lose your memory by ________.

A. getting too old　　　　 　 B. hardly using your brain

C. working too hard　　 　　　 D. using your brain too much

2.To fight forgetting effectively, we're advised to ________.

A. go back to what was learned regularly

B. break down materials into small pieces

C. focus on both ends of a learning period

D. take breaks to give the brain a good rest

3. During the learning process the brain need breaks to ________.

A. use the right side of the brain

B. revise newly learnt materials

C. take in what has been learnt

D. relax the left side of the brain

4.Where is this text most probably taken from?

A. Science fictions.　 　 B. Students’ literature.

C. An advertisement.　 　 D. A science report.

The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.

Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can't stay under the water's surface for any length of time. To explore deep water, man faces even more dangers and problems.

A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.

When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles. The diver is then suffering from the bends. The bends can cause a diver to double up in pain. They can even kill him.

1.On the whole, this passage is about ________.

A. special mixtures of gases in deep sea

B. the problems man faces in deep sea diving

C. air pressure under the surface of sea water

D. a kind of illness that man suffers in the sea

A. deep divers should be in good health

B. divers explore the deep sea only for treasure
