Question

【题目】 Imagine you are on a long car trip. It is night and you take a wrong turn onto a dark country road. With a sinking feeling, you realize that you have no idea where you are.

【1】, and the answer is written in light. A shining compass face, with north, south, east and west at the four points, and a big needle are pointing at north. What a relief! You turn your car around and head in the right direction guided by the sky.

For migrating birds, finding their way over long distances through the darkest nights is their second nature. 【2】 — directions written by light and magnetism (磁力). Some birds journey thousands of miles in their twice-yearly journeys. 【3】, like mountain ranges and rivers, to help decide the directions; but birds may also navigate using the stars, and by sensing — or even “seeing” — the Earth’s invisible magnetic field.

For many years, scientists have been studying what’s behind the strong ability of migrating birds to find their way to their winter and summer homes. Here is one thing that they agree on. 【4】. This compass leads them to make their very first autumn flight in the direction that has been long-travelled by the rest of their species. 【5】.

A.Then you glance up at the sky

B.So birds are born knowing which way home is

C.They do it in part by reading directions in the sky

D.Magnetism is important for all animals, especially birds and fishes

E.When they’re on the way, they take the advantage of familiar landmarks

F.Migratory baby birds are already equipped with a kind of present inner compass

G.In birds, migration means two-way journeys — onward journey and backward journey

Answer 1

【答案】

【1】A

【2】C

【3】E

【4】F

【5】B

【解析】

这是一篇说明文。文章主要讲述了候鸟为何拥有寻找方向的能力的原因。

【1】根据后文“You turn your car around and head in the right direction guided by the sky.( 你把车掉头，在天空的指引下朝着正确的方向行驶。)”可知，设空内容应与天空有关。选项A“Then you glance up at the sky(然后你仰望天空)”符合语境，且对应后文“and the answer is written in light”中light(光)。故选A项。

【2】根据后文“directions written by light and magnetism(由光和磁指示方向)”可知，设空内容与指示（directions）有关。C项“”符合语境。故选C项。

【3】根据后文“like mountain ranges and rivers, to help decide the directions(像山脉和河流一样，帮助决定方向)”，可知，E项“When they’re on the way, they take the advantage of familiar landmarks”中的landmarks与mountain ranges and rivers相呼应。故选E项。

【4】根据后文“This compass leads them to make their very first autumn flight in the direction that has been long-travelled by the rest of their species.( 这个指南针指引着它们第一次在秋天朝着其他物种早已走过的方向飞行。)”可知，空后句中的compass有定冠词the作限定词，表特指，因此设空内容应与指南针有关。选项F“Migratory baby birds are already equipped with a kind of present inner compass.( 候鸟宝宝已经具备了一种现有的内在指南针)”符合分析。故选F项。

【5】根据前一句内容“This compass leads them to make their very first autumn flight in the direction that has been long-travelled by the rest of their species.( 这个指南针指引着它们第一次在秋天朝着其他物种早已走过的方向飞行。)”可知，设空句应是对前文的承接总结。选项B“B. So birds are born knowing which way home is(所以鸟儿生来就知道回家的路)”符合分析。故选B项。

七选五技巧之词语复现显神功

词语复现是七选五在语篇衔接过程中的一个重要手段。因此利用词语复现解决七选五十分管用。比如文章的第1小题：

___1___, and the answer is written in light. A shining compass face, with north, south, east and west at the four points, and a big needle are pointing at north. What a relief! You turn your car around and head in the right direction guided by the sky.

利用词语复现原则，可以在段末看到词汇“you; the sky”，因此选项A. Then you glance up at the sky可为正确答案。
