A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases __3.__. He can carry a tank of air on his back and breathe through a nose and mouth piece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea _4.__. 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 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 __5.__ .

B. Scientists are trying to find more about the sea.
C. For thousands of years, he could sail on it.

【解析】
试题分析:自古以来为了利用更多的海洋资源,人们都在不断得探索着神秘的海洋世界,即使冒着很大的危险。比如潜水员,他在海底时承受着数吨重的水压,而且当他从深海中上升到海面时,稍微的不慎都会给身体带来很大伤害,甚至导致死亡。
1.C考查根据上下文的推理判断能力。从下文But 可知此处应与下句构成转折关系,而选项C中的sail on it恰好与下句中的beneath its surface 形成意思上的对比,故C选项正确。
2.G考查根据上下文的推理判断能力。前句讲人们不能到离海面很深的地方,后句又讲到人不能再深海处呆很长时间,而且下文又出现了To explore deep water,综合以上提示信息,我们可以判断此空应该是和大海深处有关,纵观选项只有G符合语境。
3.E考查根据上下文的推理判断能力。上下文内容均讲述潜水员在深海潜水时所配备的装备器械等,而E选项内容就是讲穿潜水衣、带氧气泵的,恰好符合语境,所以E为正确选项。
4.A考查根据上下文的推理判断能力。上文提到人在深海中要承受几吨重的水压而后句When a diver is under great pressure也讲到水压,由此判断A选项符合语境,所以正确选项是A。
5.D考查根据上下文的推理判断能力。上文提到人在深海上升过快时会导致严重后果,增加疼痛,而D选项恰恰能和上文这一内容相衔接,所以正确选项是D。
考点:考查信息匹配。
