Question

根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項
The sea has always interested man. From it they can get food, minerals, and treasure. __小題1:__ But he could not go far beneath its surface __小題2:__. 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 __小題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 _小題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 (氣泡). The diver is then suffering  from the bends (潛水夫病).The bends can cause a diver to double up in pain __小題5:__ . 

A．His body is under great pressure.

B．Scientistsaretryingtofindmoreaboutthesea.

C．Forthousandsofyears,hecouldsailonit.

D．Theycanevenkillhim.

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.

Answer 1

小題1:C
小題2:G
小題3:E
小題4:A
小題5:D

試題分析：自古以來為了利用更多的海洋資源，人們都在不斷得探索著神秘的海洋世界，即使冒著很大的危險。比如潛水員，他在海底時承受著數(shù)噸重的水壓，而且當他從深海中上升到海面時，稍微的不慎都會給身體帶來很大傷害，甚至導致死亡。
小題1:C考查根據(jù)上下文的推理判斷能力。從下文But 可知此處應與下句構(gòu)成轉(zhuǎn)折關(guān)系，而選項C中的sail on it恰好與下句中的beneath its surface 形成意思上的對比，故C選項正確。
小題2:G考查根據(jù)上下文的推理判斷能力。前句講人們不能到離海面很深的地方，后句又講到人不能再深海處呆很長時間，而且下文又出現(xiàn)了To explore deep water,綜合以上提示信息，我們可以判斷此空應該是和大海深處有關(guān)，縱觀選項只有G符合語境。
小題3:E考查根據(jù)上下文的推理判斷能力。上下文內(nèi)容均講述潛水員在深海潛水時所配備的裝備器械等，而E選項內(nèi)容就是講穿潛水衣、帶氧氣泵的，恰好符合語境，所以E為正確選項。
小題4:A考查根據(jù)上下文的推理判斷能力。上文提到人在深海中要承受幾噸重的水壓而后句When a diver is under great pressure也講到水壓，由此判斷A選項符合語境，所以正確選項是A。
小題5:D考查根據(jù)上下文的推理判斷能力。上文提到人在深海上升過快時會導致嚴重后果，增加疼痛，而D選項恰恰能和上文這一內(nèi)容相銜接，所以正確選項是D。
