【解析】

現(xiàn)在素食主義越來越受歡迎，受歡迎的原因和溫室氣體的排放有關(guān)，其次人們認(rèn)為殺害動(dòng)物是不道德的，社會(huì)媒體也被認(rèn)為是素食主義增加的背后原因。但專家們也想提醒人們，肉類對(duì)我們的健康很重要。嚴(yán)格的素食飲食不能總是提供人體所需的礦物質(zhì)和維生素。因此，在決定成為素食主義者之前一定要慎重考慮。

【1】句意：據(jù)《赫夫郵報(bào)》報(bào)道，美國有300多萬人是素食主義者。根據(jù)后面的句子“In the UK, about 542,000 people turned vegan during the last decade.”在英國，近十年來約有542000人變成了素食主義者。此處列舉兩個(gè)事例來說明素食主義在許多地方已成為一種更受歡迎的生活方式，故答案選C。

【2】句意：一個(gè)原因可能是人們希望減少溫室氣體排放。根據(jù)前面的句子“So why exactly has veganism become so popular?”那么為什么素食主義變得如此流行呢？前文提出為什么，后面必定要解釋原因，故答案為E。

【3】句意：這個(gè)數(shù)字甚至超過了世界上所有汽車、火車和飛機(jī)的總和。根據(jù)前面的句子“These factors are believed to account for 18 percent of the world’s greenhouse gas emissions, according to a 2013 study by the UN Food and Agriculture Organization.”這些因素被認(rèn)為占世界溫室氣體排放量的18%。根據(jù)聯(lián)合國糧食及農(nóng)業(yè)組織2013年的一項(xiàng)研究， 此句解釋了18%這一數(shù)字甚至超過了世界上所有汽車、火車和飛機(jī)的總和。故答案為B。

【4】句意：據(jù)英國廣播公司新聞報(bào)道，社會(huì)媒體也被認(rèn)為是素食主義增加的背后原因。根據(jù)后面的句子“Vegan famous people are able to use social media to spread their message and share tips about living a vegan lifestyle.”素食主義名人能夠利用社交媒體傳播他們的信息，分享關(guān)于素食生活方式的建議。因此上句會(huì)說社會(huì)媒體也被認(rèn)為是素食主義增加的背后原因。答案為D。

【5】句意：因此在你決定成為一個(gè)素食主義者之前，你可能要好好考慮一下。根據(jù)前面的句子“But experts also want to remind people that meat is important for our health. A strict vegan diet cannot always offer the minerals and vitamins that a human body needs.”專家們提醒人們?nèi)忸悓?duì)我們的健康很重要，嚴(yán)格的素食飲食不能總是提供人體所需的礦物質(zhì)和維生素。因此，在決定成為素食主義者之前一定要慎重考慮。故答案為A。

【題目】 The human body is a machine that can raise lots of interesting questions. Why, for example, are yawns（呵欠）contagious（傳染的）? What's up with ice-cream headaches? Here are answers to these and other questions about our bodies.

Why do I get a headache when I eat ice cream too quickly?

Scientists aren't exactly sure what causes the brain freeze when we eat ice cream or other super cold foods too quickly, though some believe it's the result of changed blood .flow in the nervous system. Blood vessels in the head tighten to stop the loss of body heat and then relax to let blood flow rise; that sudden rush of blood is what causes the headache. You can improve an ice-cream headache by rapidly rubbing your tongue across the roof of your mouth to help warm up things.

What causes my stomach to make a low continuous noise when I'm hungry?

Actually, your stomach makes noise whether you're hungry or full; you just hear it more clearly when you're hungry. Think of your digestive tract（消化道）as a really long tube lined with smooth muscle tissue. These muscles move food, fluids and gas through your digestive tract. ____________________________. It can make you feel embarrassed尷尬的）but is nothing to worry about.

Why do I blush when I'm embarrassed?

When you're embarrassed, your brain releases a shot of adrenaline（腎上腺素）, which makes your heart race and blood vessels become larger in size. All this happens to increase blood flow and oxygen delivery throughout the body in a fight-or-flight reaction（對(duì)抗反應(yīng)）. There are a lot of tiny blood vessels in your face, which turn noticeably redder from this sudden rush of blood. As for the actual function of blushing, researchers are still trying to find that one out.

Why are yawns contagious?

Have you ever yawned in front of someone, only to have them yawn right back? It's a common thing, but researchers don't have a good explanation for it. They do, however, know this happens only with humans and chimpanzees(黑猩猩）. A bigger question puzzling scientists is why we yawn at all. It used to be thought that yawning showed that oxygen to the brain was not enough, but that's just a myth. A growing body of research now shows that yawning is nature's way of keeping our brains cool.

【1】What is the meaning of the underlined word tighten?

A. 變松B. 變緊C. 變短D. 變長

【2】Which of the following sentences can be filled in the blank?

A. And that's what you're hearing when your stomach makes noise.

C. And that's what makes you feel uncomfortable when you're full.

D. And that's how it makes a difference to your digestive tract.

【3】Which of the following statements is TRUE?

A. There is no way for you to improve an ice-cream headache.

B. Researchers have found out the actual function of blushing.

C. Your stomach makes noise only when you are hungry.

D. Researchers don't have a good explanation for why yawns are contagious.

【4】What is the best title of the passage?

A. Some Interesting FactsB. Our Strange Body

【題目】閱讀短文，并按要求完成以下題。

Critical thinking(批判性思維) is trying to improve the way you think. People use critical thinking in every area of life to solve problems and evaluate claims(評(píng)估主張).

Like every other skill, critical thinking takes practice. When a problem comes our way, we need to think critically to decide how to solve it. When we see an advertisement, for example, we should stop and think. Advertisements are made to make people feel certain that they are true, and then people can buy the products. But is what the advertisement says true? Is it making a claim? Or does it only interest us? Critical thinking is important and stops us from making poor choices. In fact, we are using it if we ask questions naturally about what we see.

Practice makes perfect. While you are growing in critical thinking, you’ll become a wiser and more thoughtful person. There are many ways of doing practice. Here are a few.

★ Read about a topic people disagree on. Look at articles or books on all sides of the subject. For each side of the subject, think carefully and evaluate it.

★ When you see or hear a claim, ask questions about it. Who is making the claim and why?

★Evaluate your own thinking. Where and why do you think uncritically? How can you improve?

Critical thinking should be part of everything we do. It may help you to succeed at work or school. Make yourself into a habit of critical thinking. Change your thoughts and change your world.

1、2題完成句子；3題簡(jiǎn)略回答問題；4題找出并寫下第二段的主題句；5題將文中畫線句子譯成漢語。

【1】People use critical thinking to _____________________________ and evaluate claims.

【2】Critical thinking can stop us from _____________________________.

【題目】 What does it take to graduate from university? Some papers or high scores in exams? Well, these are not enough if you are a student at Tsinghua University.

According to a new rule of the university, students must prove (證明) themselves in the swimming pool. They need to pass a swimming test of at least 50 meters, and those who fail the test will be required to take a swimming course throughout their school years. By the time they graduate, they will have known how to swim; otherwise they can’t graduate with their bachelor’s degrees (學(xué)士學(xué)位).

The news made waves in Chinese social media (媒體). Some people praised the university for requiring a necessary skill that can save lives, and they also believed that the rule would help improve students’ health. However, others questioned if it was fair to expect those who come from inland cities (內(nèi)陸城市) to be able to swim.

In fact, this is not a new rule. Tsinghua University first made swimming a requirement in 1919 but later gave it up because the number of students became too large and there were not enough swimming pools in the school for them to learn swimming.

Anyway, it is still good news that Chinese students’ health has become more and more valued. Why not just take this chance to learn one more life-saving ability?

【1】According to the passage, what does it take for a student to graduate from Tsinghua university?

【2】The underlined phrase “made waves” in Paragraph 3 most probably means _________.

A. caused a heated discussionB. spread widely

【3】Why did Tsinghua University once give up the rule?

① Because many students failed the swimming test.

② Because some people disagreed with the rule.

③ Because there were too many students.

④ Because there were not enough swimming pools.

A. ①②B. ②③C. ③④D. ①④

【4】What is the passage mainly about?

A. Different people hold different opinions about a new rule.

B. Tsinghua University has made a new rule of graduation.

C. Chinese students’ health should be more and more valued.

D. There is a new chance to learn another life-saving ability.
