Randall Munroe, who used to work on robots at NASA, explains science in a fun and easy-to-understand way in his book What If? Once you get used to his unique writing style, you can go on many amazing trips with him and learn while laughing.
And you will certainly learn. There is a sort of joy in getting real answers to the strange questions Munroe is sent every day. However unusual the topics are, Randall takes them seriously. For example, if you set a meat-eating dinosaur(恐龙) free in New York City, how many humans would it have to eat to meet its need each day? Munroe thinks New York could support about 350 dinosaurs. That's good to know, but we hope we don't need to use this information.
The book's cover is a full-size picture of what the Earth would look like if the oceans were removed. The back has some interesting facts you might want to know before buying it (eating the book would give you about 2,300 calories(卡路里) if you could take in paper). Thanks, Randall!
Although Munroe knows a lot and can perfectly explain the science behind the questions, What If? is not a textbook. When asked what would happen when you threw a baseball at light-speed, he says there would be a shockwave expanding(膨胀) outwards, and quickly moves on. He is answering the question after all, but if you are looking for detailed classroom-style descriptions of what Munroe is talking about, you're out of luck.
But that's what makes it great. What If? is light enough to attract you, but deep enough to make you curious about science one chapter at a time. If you're willing to go along with Munroe's ideas and guesses, you're in for an exciting journey of the mind.
()1. What can be found in the book What If?
A. Stories of fun journeys.
B. Pictures of the oceans.
C. Latest scientific experiments.
D. Discussions of unreal situations.
()2. How does Munroe deal with the questions in his book?
A. He offers direct answers.
B. He pays no attention.
C. He recommends textbooks.
D. He digs into many possibilities.
()3. What is Munroe's writing style like?
A. Formal and detailed.
B. Light but confusing.
C. Humorous and educational.
D. Imaginative but unclear.
()4. Which of the following can be the best title for the text?
A. What If? : A Collection of Funny Science Jokes

C. What If? : A Guidebook on Healthy Eating Habits
D. What If? : A Question-based Book about Life

【语篇解读】本文是一篇说明文。文章主要介绍了兰德尔·门罗所著的《那些古怪又让人忧心的问题》一书，包括其内容、写作风格以及与读者的互动方式等。
1. D 解析:细节理解题。根据第二段中“However unusual the topics are, Randall takes them seriously. For example, if you set a meat-eating dinosaur free in New York City, how many humans would it have to eat to meet its need each day?(无论话题多么不寻常,兰德尔都会认真对待。例如,如果你在纽约市放生一只食肉恐龙,它每天需要吃多少人类才能满足需求?)”可知,书中讨论了一些不切实际的情况。因此,在《那些古怪又让人忧心的问题》这本书中可以发现对不切实际情况的讨论。故选 D。
2. A 解析:细节理解题。根据第四段中“Although Munroe knows a lot and can perfectly explain the science behind the questions, What If? is not a textbook. When asked what would happen when you threw a baseball at light-speed, he says there would be a shockwave expanding outwards, and quickly moves on.(虽然门罗知道很多,并且可以完美地解释这些问题背后的科学,但《那些古怪又让人忧心的问题》不是教科书。当被问及以光速投掷棒球会发生什么时,他说会有一个冲击波向外膨胀,然后很快就继续讲其他内容了)”可知,门罗对于书中的问题给出了直接的答案,并没有深入探讨或推荐教科书等。故选 A。
3. C 解析:推理判断题。根据第一段中“Randall Munroe, who used to work on robots at NASA, explains science in a fun and easy-to-understand way in his book What If? (兰德尔·门罗曾在 NASA 从事机器人工作,他在《那些古怪又让人忧心的问题》一书中以有趣且易于理解的方式解释科学)”和“Once you get used to his unique writing style, you can go on many amazing trips with him and learn while laughing.(一旦你习惯了他独特的写作风格,你就可以和他一起踏上许多奇妙的旅程,在欢笑中学习)”可知,门罗的写作风格既幽默又富有教育意义。故选 C。
4. B 解析:标题归纳题。通读全文,尤其结合第一段的内容“兰德尔·门罗曾在美国国家航空航天局从事机器人相关工作,他在《那些古怪又让人忧心的问题》一书中以有趣且易于理解的方式解释科学。一旦你适应了他独特的写作风格,就能与他一同开启许多奇妙的旅程,在欢笑中学习”可知,文章主要介绍了兰德尔·门罗所著的《那些古怪又让人忧心的问题》一书,包括其内容(讨论不切实际的情况)、写作风格(幽默且富有教育意义)以及与读者的互动方式等。因此,最适合作为本文标题的是“What If? : A Scientific Adventure with Munroe(《那些古怪又让人忧心的问题》:与门罗一起的科学冒险)”。该标题既体现了书名的原意,又概括了文章的主要内容。故选 B。
