Just because they can’t sing opera or ride a bicycle doesn’t mean that animals don’t have culture. There’s no better example of this than killer whales. As one of the most【C1】______predators (食肉动物), killer whales may not fit the【C2】______of a cultured creature. However, these beasts of the sea do display a vast range of highly【C3】______behaviors that appear to be driving their genetic development.
The word " culture" comes from the Latin " colere," which【C4】______means " to cultivate. " In other words, it refers to anything that is【C5】______or learnt, rather than instinctive or natural. Among human populations, culture not only affects the way we live, but also writes itself into our genes, affecting who we are. For instance, having spent many generations hunting the fat marine mammals of the Arctic, the Eskimos of Greenland have developed certain genetic【C6】______that help them digest and utilize this fat-rich diet, thereby allowing them to【C7】______in their cold climate.
Like humans, killer whales have colonized a range of different【C8】______across the globe, occupying every ocean basin on the planet with an empire that【C9】______from pole to pole. As such, different populations of killer whales have had to learn different hunting techniques in order to gain the upper hand over their local prey (猎物). This, in turn, has a major effect on their diet, leading scientists to【C10】______that the ability to learn population-specific hunting methods could be driving the animals’genetic development.
A) acquired I) image
B) adaptations J) literally
C) brutal K) refined
D) deliberately L) revolves
E) expressed M) speculate
F) extends N) structure
G) habitats O) thrive
F) extends N) structure
H) humble [br] 【C6】
选项
答案
B
解析
名词辨析题。空格前面是形容词genetic,而certain此处含义为“某些”,因此应填入名词复数。空格所在处意思是“格陵兰岛的爱斯基摩人发展出某些基因______来帮助他们消化利用富含脂肪的饮食”。由此可推断,爱斯基摩人的基因发生了变化,因此本空应填人含有“变化、改变”意义的名词,故本题答案为B)adaptations“改变,适应”。另一个备选名词复数G)habitats不符合句意,因此排除。
