阅读理解题 第31题 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. 1．阅读理解 On the whole, this passage is about _______ .
