The sea has always interested man. From it he can get food, minerals, and treasure. 51 But he could not go far beneath its surface.
52 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. 53 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. 54
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(气泡). The diver is then suffering from the bends(潜水夫病). The bends can cause a diver to double up in pain. 55

E. He can wear a diving suit and have air pumped to him from above. F. The water pressure can cause a diver to breathe with difficulty. G. Man wants to explore deep into the sea.
