答案

1. B 句意为:飞行机器人可以把邮件送到人们的家里…… 根据空后的 mail to people's houses 可知是飞行机器人把信件携带到人们家里,carry 符合语境。故选 B 项。
2. A 根据上文的“In recent years, with more and more cars on the road, flying robots are used to deliver mail.”可知此处指交通。故选 A 项。
3. A 句意为:一家研究中心正试图在信鸽的帮助下改善其飞行机器人。根据下文讲到的让飞行机器人和信鸽一起送信件可推出,此处指在信鸽的帮助下,故用“with the help of...”,表示“在……的帮助下”。
4. C 根据空后的 to fly home from somewhere else 可知信鸽是经过特殊训练的,specially 符合题意。
5. D 句意为:在测试中,研究人员发现,信鸽返回家园的效率比飞行机器人更高。根据语境,故选 D 项。
6. B 句意见上一题解析。根据空后的 than 和语境可知此处要用 efficient 的形容词比较级 more efficient,表示“更高效的”。
7. A 句意为:所以研究中心正在尝试使用一个飞行机器人和一只信鸽一起来投递信件。上下文都在讲信鸽对飞行机器人的帮助,故此处是说让信鸽和飞行机器人一起投递信件。

8. C 句意为:机器人完成任务后,它可以在最可能短的时间内跟随鸽子返回。上文讲到机器人返途耗时太久,又讲到信鸽擅长返回家园,由此可推出是让机器人跟随信鸽返回,follow 符合语境。故选 C 项。
9. D 句意为:尽管养鸽子会花费更多的钱,但是研究中心表示,这样可以节省时间。上文讲到要让信鸽辅助飞行机器人送信件,结合选项可推出此处是指养鸽子,raise 符合语境。故选 D 项。
10. D 根据下文的 And the time it saves 可知此处是说节省时间,save 符合语境。故选 D 项。

Humans’ Greatest Achievements
The Earth is 4.5 billion years old, but the human race has lived on it for just 200,000 years. In that short time, we have achieved some amazing things.
D
11 The list is almost endless. The invention of the airplane has changed our lives. The discovery of antibiotics(抗生素)has saved the lives of millions of people. Can you imagine living without electricity? What about the printing press? Without the printing press, you wouldn’t be reading this. In the last 50 years, there have been great achievements in communication, such as radios, TVs, computers, the internet, and smartphones. We could probably live without them, but life wouldn’t be as interesting.
What about the arts? The arts have brought pleasure to many people, but are the Beatles and Bach more important than antibiotics?
E
12
Finally, we must not forget humans’ early achievements.
C
13 We can’t imagine modern life without cooked food and cars.
What are humans’ greatest achievements? To answer the question, we need to decide what we mean by “great”.
A
14 Or is it just something that makes us say “Wow” like the Great Wall? What do you think?
A. Is it something that makes us rich or happy or saves lives?
B. We enjoy these things every day because they are free to use.
C. They used fire for cooking and heating and invented the wheel.
