小伙伴们，GRE考试大家复习的怎么样了呢？下面是帮考网分享的一些GRE考试阅读部分的复习资料，一起来看看吧！

Some researchers claim that cetaceans—whales and dolphins—have culture, which the researchers define as the ability to learn from one another. Skeptics, however, demand clear evidence that cetaceans can acquire new behaviors through some form of social learning, preferably clear-cut instances of imitation or teaching. But such evidence is difficult to obtain. While few people doubt that captive cetaceans are adept at imitation or that they reproduce behaviors taught by researchers, biologists seeking insight into cetaceans’ behavior in their natural habitats must rely on deduction rather than experiments. If members of a particular group share behaviors that do not result from genetic inheritance or environmental variation, then they have almost certainly learned them by watching, following, or listening to other animals.

1. Which of the following best describe the function of the highlighted sentence?

A. It identifies a factor that complicates biologists’ ability to draw conclusions about the behavior of cetaceans in their natural environments.

B. It illustrates the kind of deduction mentioned in the preceding sentence.

C. It explains why skeptics have remained unpersuaded by evidence that has been put forward in support of the claim that cetaceans have culture.

D. It introduces a claim that would be dismissed by both supporters and opponents of the view that cetaceans have culture.

E. It notes a previously overlooked factor that might shed light on the question of whether cetaceans have culture.

2. The passage suggests which of the following about captive cetaceans?

A. Whether they are engaged in social learning is a subject of disagreement among biologists.

B. Their ability to imitate new behaviors is more extensive than that of noncaptive cetaceans.

C. They exhibit few behaviors that have not also been observed in cetaceans in their natural habitats.

D. They appear to adopt new behaviors more quickly than noncaptive cetaceans.

E. They exhibit tendencies that suggest a capacity for the kind of behavior that qualifies as cultural.

1

Some researchers claim that cetaceans — whales and dolphins — have culture, which the researchers define as the ability to learn from one another.

一些研究者认为鲸目动物 —— 鲸和海豚 —— 拥有文化，研究者把它定义为互相学习的能力。

2

Skeptics, however, demand clear evidence that cetaceans can acquire new behaviors through some form of social learning, preferably clear-cut instances of imitation or teaching.

然而对此持怀疑态度的人，要求给出鲸目动物可以通过某种社交学习的形式，习得新行为的确定证据，最好是清晰无误的模仿或教学的例子。

3

But such evidence is difficult to obtain.

但这种证据不易获得。

4

While few people doubt that captive cetaceans are adept at imitation or that they reproduce behaviors taught by researchers, biologists seeking insight into cetaceans’ behavior in their natural habitats must rely on deduction rather than experiments.

尽管没什么人怀疑，被圈养的鲸目动物擅长模仿，或者说它们复制研究者教给它们的行为，但想要理解自然栖息地的鲸目动物的行为，生物学家必须依赖推演，而不是实验。

5

If members of a particular group share behaviors that do not result from genetic inheritance or environmental variation, then they have almost certainly learned them by watching, following, or listening to other animals.

如果某个群体的成员都具有一些，并非来自于基因遗传或环境改变(造成)的行为，那么几乎可以确定它们是通过观察，跟随或听从其他动物而习得的。
