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. Because he must breathe air, he can not 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 its back and breathe through a hose 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 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 (潜水员病). The bends can cause a diver to double up in pain. They can even kill him.
26. On the whole, this passage is about -----.
a) special mixture 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
27. A diver’s body in deep water -----.
a) is under great pressure
b) is just like that of a fish
c) suffers from the bends
d) weighs very little
28. The passage does not say, but it makes you think that -----.
a) deep-sea divers should be in good health
b) divers explore the deep sea only for treasure
c) diving under water too quickly causes a kind of illness
d) there is a special mixture of gases under the sea
29. Why does a diver get the bends?
a) He tries to do exercises under the water.
b) His diving suit weighs too much.
c) He comes to the surface too quickly.
d) The air in his blood is used up.
30. From the passage we can see that -----.
a) The sea began to interest man in the last few years.
b) Man is not at home deep in the sea.
c) All divers will get the bends sooner or later.
d) The air in the seawater will kill a diver if he is not careful. 展开
