Question

【题目】

A If we laid all of the blood vessels (血管) in the human body end to end, they would reach about 100,000km long. That’s nearly two and a half times around Earth!

B For the first time, Coca-Cola has showed that it uses 3,000,000 tons of plastic bottles each year. That’s the weight of 15,000 blue whales-the largest animal on Earth.

C If your throat tickles (发痒), pressing your ear might make it go away. That’s because your throat and ears share the same group of nerves (神经). When you press your ear, the nerves in your throat can feel it.

D It takes about 7 to 8 trees to make enough O2 for one person to breathe for a year. Each person needs around 750kg of O2 per year. A large tree might make around 100kg of O2 per year.

E To young children, a year might seem to last forever. But older people might say that it flies by. Why is that? According to the US scientists, young people’s brains deal with information faster than older people. They take in more information and do more things in a day. So they feel like each day lasts longer. However, older people’s brains take in less information and see a day pass more quickly.

F About 200 muscles (肌肉) work together when you take a step. That’s a lot of work for your muscles, since many people take about 10,000 steps a day. If you want to get some easy exercise, walking is good for you.

【4】A

【5】C

【解析】

短文大意：短文以庞大的数字揭示了一些令人惊愕的事实，以帮助人们更多地了解人体和环境保护。

【1】题意：将段落A~F与两个主题匹配：①人与环境；②人体。以下哪一项是正确的？考查主旨归纳。根据A:If we laid all of the blood vessels in the human body end to end; C:If your throat tickles, pressing your ear might make it go away; E: According to the US scientists, young people’s brains deal with information faster than older people. 和F: About 200 muscles work together when you take a step.可知the blood vessels（血管）/ throat（喉咙）/ear（耳朵）/brains（大脑）和muscles（肌肉）都是人体器官，与主题②The Human Body相符；根据B: For the first time, Coca-Cola has showed that it uses 3,000,000 tons of plastic bottles each year. 和D: It takes about 7 to 8 trees to make enough O2 for one person to breathe for a year.可知两个段落介绍的是人们所处的外部环境，符合①People & Surroundings主题。综合以上分析，故选C。

【2】题意：所有六个段落最好的标题是什么?考查标题归纳。A. 奇怪的世界；B. 惊人的事实；C. 难以置信的数字。根据六个段落的内容可知，每个庞大的数字都与一个惊人的事实相联系，例如A段If we laid all of the blood vessels in the human body end to end, they would reach about 100,000km long. That’s nearly two and a half times around Earth!意思是：人体所有的血管首尾相连的长度几乎是地球的2.5倍，虽然让人惊愕但却是事实；Amazing Facts符合文意，故选B。

【3】题意：为什么编辑要给读者呈现这六段?考查主旨理解。根据各段内容可知，BD是环境主题，ACEF是人体主题，所以作者的目的是让我们更多地了解人体和环境保护，To help readers know more about human body and environmental protection.符合文意，故选A。

【4】题意：下面哪个问题在文章中得到了回答?考查细节判断。根据E段Why is that? According to the US scientists, young people’s brains deal with information faster than older people.可知回答了小孩子和老年人对一年的感觉不同的原因。而D段A large tree might make around 100kg of O2 per year.和F段About 200 muscles work together when you take a step.只是陈述事实，并没有回答怎样制造氧气和全身肌肉如何协同工作。综合以上分析，故选A。

【5】题意：下面哪个选项得出“30,000”这个数字?考查细节计算。A. 通过走150步，一起运动的肌肉量。根据About 200 muscles work together when you take a step.可知200×150＝30，000。B. 三个人体中连接在一起的血管的长度。根据If we laid all of the blood vessels in the human body end to end, they would reach about 100,000km long.可知100000×3＝300，000。C. 40人一年呼吸氧气的重量。根据D段Each person needs around 750kg of O2 per year.可知750×40＝30,000。综合以上计算，故选C。
