高三英语单项填空中等难度题查看答案及解析

Jim suffered heart problems.In conversation he expressed little joy and it seemed that his life was drawing to a close.

When his heart problems led to operation,Jim went through it successfully,and a full recovery was expected.Within days,however,his heart was not beating properly.Jim was rushed back to operation,but nothing was found to explain the cause of his illness.He died on the operating table on the day before his 48th birthday.

Dr.Bruce Smoller,a psychologist(心理学家),had had many conversations with him,and the more he learned,the stranger he realized Jim’s case was.When Jim was a child,his father,a teacher,suffered a heart attack and stayed home to recover.One morning Jim asked his father to look over his homework,promising to come home from school at noon to pick it up.His father agreed,but when Jim returned his father had died.Jim’s father was 48.

“I think all his life Jim believed he killed his father,”Dr. Smoller says.“He felt that if he had not asked him to look at his homework,his father would have lived.Jim had been troubled by the idea.The operation was the trial(判决) he had expected for forty years.”Smoller believes that Jim willed himself not to live to the age of 48.

Jim’s case shows the powerful role that attitude(态度) plays in physical health,and that childhood experiences produce far-reaching effect on the health of grown-ups.Although most cases are less direct than Jim’s,studies show that childhood events,besides genes,may well cause such midlife diseases as cancer,heart disease and mental illness.

1.Jim was sent back to operation because ______.

A.his heart didn’t work well

B.he expected a full recovery

C.his life was drawing to a close

D.the first one wasn’t well performed

2.What made Dr. Smoller feel strange about Jim’s case?

A.Jim died at a young age.

B.Jim died on the operating table.

C.Both Jim and his father died of the same disease.

D.Jim’s death is closely connected with his father’s.

3.From Smoller’s words,we can infer that ______.

A.Jim’s father cared little about his study

B.Smoller agreed that Jim did kill his father

C.Jim thought he would be punished some day

D.Smoller believed Jim wouldn’t live to the age of 48

4.Which of the following could have strong effect on one’s physical health according to the text?

A.a,b,d                                 B.a,b,e

C.a,c,e                                 D.b,c,d

If a diver surfaces too quickly, he may suffer the bends. Nitrogen(氮) dissolved(溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles (气泡)accumulate in a joint, is sharp pain and a bent body—thus the name. If the bubbles form in his lungs or his brain, the consequence can be death.

Other air-breathing animals also suffer this decompression(减压) sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs. That these ancient sea animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil (化石)bones that have caved in on them selves are thus a sign that the animal once had the bends.

Bruce Rothschild of the University of Kansas knew all this when he began a study of ichthyosaur bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompression over the 150 million years. To this end, he and his colleagues traveled the world’s natural-history museums, looking at hundreds of ichthyosaurs from the Triassic period and from the later Jurassic and Cretaceous periods.

When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before they died, but not a single Triassic specimen(标本) showed evidence of that sort of injury.

If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly—and, most strangely, they lost it afterwards. But that is not what Dr Rothschild thinks happened. He suspects it was evolution in other animals that caused the change.

Whales that suffer the bends often do so because they have surfaced to escape a predator (捕食动物) such as a large shark. One of the features of Jurassic oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaur lunches. Triassic oceans, by contrast, were mercifully shark- and crocodile-free. In the Triassic, then, ichthyosaurs were top of the food chain. In the Jurassic and Cretaceous, they were prey(猎物) as well as predator—and often had to make a speedy exit as a result.

1.Which of the following is a typical symptom of the bends?

A. A twisted body.　　 B. A gradual decrease in blood supply.

C. A sudden release of nitrogen in blood.　　 D. A drop in blood pressure.

2.The purpose of Rothschild’s study is to see________ .

A. how often ichthyosaurs caught the bends　　 B. how ichthyosaurs adapted to decompression

C. why ichthyosaurs bent their bodies　　 D. when ichthyosaurs broke their bones

3.Rothschild’sfindingstatedinParagraph4 .

A. confirmed his assumption　　 B. speeded up his research process

C. disagreed with his assumption　　 D. changed his research objectives

4.Rothschild might have concluded that ichthyosaurs.

A. failed to evolve an anti decompression means

B. gradually developed measures against the bends

C. died out because of large sharks and crocodiles

D. evolved an anti decompression means but soon lost it
