问题 共用题干Craig Rogers was sitting on his surfboard, scanning（审视）the distance for his next wave, when his board suddenly stopped moving._________(46)"I could have touched its eye with my elbow（肘部）,"says Craig. The shark had surfaced so quietly that he hadn't heard a thing.
In his horror and confusion,he waved his arms and accidentally cut two of his fingers on the shark's teeth.He then slid off the opposite side of his surfboard into the water. Then,with Craig in the water and blood flowing from his fingers,the five-meter-long shark simply swam away,_______(47)
Although sharks are often categorized as killers that hunt and eat as many humans as they can, this is actually inaccurate.Sharks very rarely kill humans.A person has a greater chance of being struck by lightning or drowning（淹死）in a bath than of being killed by a shark. Only 74 people have been reported killed by great whites in the last century.But great white sharks can reach six meters in length and weigh 2,200 kilograms or more.With frightening jaws that can hold up to
3,000 teeth arranged in several rows,they could very easily kill and eat a helpless human in the water.________(48)Shark researchers are trying to comprehend the reasons that allow people to escape without being eaten.
The most common explanation is that great whites don't see well._________(49)There is reason to doubt this,however. Recent information shows that great whites can actually see very well. Also,when attacking seals,great whites shoot up to the surface and bite with great force.When approaching humans,however,_________(50)They soon discover that humans are not a high一fat meal."They spit us out because we're too bony,"says Aidan Martin,director of Reef Quest Center for Shark Research.
Shark researchers like Martin hypothesize that great whites are actually curious animals that like to investigate things.It's possible that they use their bite not only to kill and eat,but also to gather information.Although such an experience is unlucky for people like Craig Rogers,when sharks bite surfboards or other objects or people,they are likely just trying to learn what they are._________（47）A:disappearing into the water below.B:Why is it,then,that most people survive attacks by great whites?C:they most often move in slowly and bite less hard.D:There is reason to doubt that great whites see well enough to attack humans.E:It has been thought that they mistake people for the seals or sea lions which make up a large part of their diet.F:He looked down and was terrified to see a great white shark biting the front of his board.
选项 _________（47）
A:disappearing into the water below.
B:Why is it,then,that most people survive attacks by great whites?
C:they most often move in slowly and bite less hard.
D:There is reason to doubt that great whites see well enough to attack humans.
E:It has been thought that they mistake people for the seals or sea lions which make up a large part of their diet.
F:He looked down and was terrified to see a great white shark biting the front of his board.
答案 A
解析 “F.He looked down and was terrified to see a great white shark biting the front of his board.”前一句说：······就在这时冲浪板不动了。F在句意上是接着这一句的。意为“他低头向水下看，惊悚的一幕出现了：一条大白鲨正在撕咬冲浪板的前端。
前面说the five-meter-long shark simply swam away(这条五米长的鲨鱼却径直游开),因此"A.disappearing into the water below”符合逻辑。
" B.Why is it, then , that most people survive attacks by great whites ?"起承上启下的作用。前一句讲到它们可以轻易杀死并吃掉无助的落水者。该句的意思是：“但为什么大多数人受到大白鲨攻击之后都能鲨口逃生呢？”接着说，鲨鱼研究者们正在努力寻找使得人类鲨口脱险的原因。       
"E.It has been thught that they mistake people for the seals or sea lions which rnake up a large part of their diet.’前沂句讲封最常提的解释是说大白鲨的视力不好。E 项是人们认为大白鲨会把人类错当成是其主要食物来源的海豹飞或海狮。前一句是原因，后一句是结果。
“C.they most often move in slowly and bite less hard.”结合空格句的前一句，意思是：“当大白鲨在攻击海豹时，他们会迅速窜上海面，用力撕咬。但当大白鲨在攻击人类时，它们在大多数情况下会慢慢浮上海面，撕咬的力度也轻得多。”
