Part II Reading Comprehension
(Skimming and Scanning)
1.【解析】[D]属同义转换题,本题是一种排除选择题。根据题干中的中心词“movement to do something”,可以将答案定位在小标题“Moving to Survive”下第二段的前两句话,“Like the shark, most animals use movement to find food. They also use locomotion to escape enemies, find a mate, and explore now territories”。该句与题干是一种同义转换,选项A、B和C在原文中均有提及,所以不是正确选项;答案D在原文没有提及,所以是正确答案。
2.【解析】[B]属细节推断题。题干考查汽车、火箭和潜艇的例子是为了说明什么,其中的“examples of automobiles, rockets and submarines”是关键词,可以将答案定位在文章小标题“Moving to Survive”下第三段的前两句话,“Humans have the added advantage of using their various inventions to move about in just about any kind of environment. Automobiles, rockets, and submarines transport humans from deep oceans to as far away as the moon”,第二句话所举例子正是为了说明句话的内容,这与B项意思一致,而其他选项在文中均未提及。
3.【解析】[A]属细节推断题。分析题干,本题考查鲨鱼在水中快速游动的关键是在什么。其中的“key”是关键词,可以将答案定位在小标题“Skin Is the Key”下首段的句话,“The biologists discovered that the skin of the shark is the key to the animal’s high efficiency in swimming through the water”,这与选项A完全一致,所以直接选择A即可。其他选项在文中均有提及,但是都不符合题干的要求。
4.【解析】[D]属细节推断题。题干中的“collagen fibers to the greatest extent”是关键词,可以将答案定位在小标题“Skin Is the Key”下第二段的句话,“The Duke University biologists have found that the greatest stretching occurs where the shark bends its body while swimming”。这与选项D的内容完全一致,所以答案选D项,而其他选项原文均未提及,为干扰项。
5.【解析】[C]属细节推断题。题干中“a belted radial tire”是关键词,可以将答案锁定在文章小标题“Source of Energy”下段的第三句话,“Just as a radial tire is inflated by pressure, so, too, is the area just under the shark’s collagen ‘radials’”。其中的“just as”和“so”正说明了两者的相似之处在于“inflated by pressure”,所以答案应该是C。选项A和B是两者的不同之处,选项D在文中没有提及。
6.【解析】[A]属细节推断题。题干中的关键词是“a laminar flow”,所以可以将答案锁定在文章小标题“Dolphin Has Speed Record”下,根据该节段的倒数第三、四句话,“Normally when a fish or other object moves slowly through the water, the water flows smoothly past the body. This smooth flow is known as laminar flow.”。题干是对这两句话的改写,所以正确答案是A选项。其他三个选项的意思均不符合“a laminar flow”的定义,与题干要求不符。
7.【解析】[C]属同义转换题。题干中“a slug”和“a mouse”均为关键词,可以直接定位在小标题“Other Animals Less Efficient”下段的第二句话,“It uses so much energy ... a mouse traveling the same distance uses only one twelfth as much energy”。题干是对该句的同义改写,所以正确答案是[C]12 times,其他选项均与原文内容不符。
8. 【解析】feeling the vibrations of a struggling prey鲨鱼靠感受猎物游动的震动来发现猎物。
9. 【解析】collagen fibers 在Skin Is the Key中,第二、三句话,The fibers are called collagen fibers.
10. 【解析】some fantastic involuntary changes 在Source of Energy中,第二段倒数句话就是本题答案。
