Question

【题目】 A new study shows that air pollution can cause a huge reduction in our intelligence. The study was a project involving researchers at Peking University in China and Yale University in the United States.

The researchers reported that long-term exposure to air pollution can affect a person's mental abilities in two areas: Language and math.

The researchers studied about 25,000 people from across China. Between 2010 and 2014, these Chinese men, women and children were given language and math tests. Then researchers compared the test results with measurements of pollution in the air, namely nitrogen dioxide and sulfur dioxide （二氧化硫）.

Xi Chen of the Yale School of Public Health led the study. He and his team found that breathing polluted air can reduce a person's education level by about one year.

Chen said that the effect generally is worse for those over 64 years of age, for men and for those with little or no education.

“The older persons—they are more affected. And we find, quite amazingly, males are more affected than females. And people working outdoors are more affected than people working indoors.

He noted that the youngest people in the study were 10 years old, while the oldest was 90 years old. They came from China's 33 provinces. In his words, the data and facts are convincing and this range of ages and locations across the country provided a real, objective and representative sample.

The researchers noted that the effect of air pollution on verbal ability is even more serious as people age, especially among men and the less educated. The researchers also stressed that every country, whether developed, developing or poor, should focus on air pollution or humans will face a bad situation.

【1】What is the result of the study?

A.Air pollution has a bad effect on people's intelligence.

B.Females are more affected by air pollution than males.

C.Americans are more affected by air pollution than Chinese.

D.People working indoors are actually not affected by air pollution.

【2】What did Chen say about the study?

A.It is doubtful.

B.It is extremely unfair.

C.It is common and not representative.

D.It is relatively objective and persuasive.

【3】What did the researchers emphasize in the last paragraph?

A.The data from the 33 provinces is convincing.

B.The whole world should pay attention to air pollution.

C.The less educated take more responsibility for air pollution.

D.Air pollution's influence on verbal ability is less serious as people age.

【4】Where is the text most likely taken from?

A.A life diary.B.A guidebook.

C.A science magazine.D.A biography.

Answer 1

【答案】

【1】A

【2】D

【3】B

【4】C

【解析】

本文是一篇说明文。一项新的研究表明，长期暴露在空气污染中会在语言和数学两个方面影响一个人的智力，因此每个国家都应关注空气污染否则人类将面临一个糟糕的局面。

【1】细节理解题。根据第二段中的“The researchers reported that long-term exposure to air pollution can affect a person's mental abilities in two areas: Language and math.”可知，研究人员报告说，长期暴露在空气污染中会在两个方面影响一个人的智力：语言和数学。即研究结果是空气污染会对人们的智力产生不良影响。故选A。

【2】细节理解题。根据倒数第二段中的“In his words, the data and facts are convincing and this range of ages and locations across the country provided a real, objective and representative sample.”可知，用Xi Chen的话说，调查得到的数据和事实令人信服，全国各地的不同年龄和不同地方的人提供了真实，客观和有代表性的研究样本。即Xi Chen对这项研究说的是“研究结果是相对客观和有说服力的。”故选D。

【3】细节理解题。根据最后一段中的“The researchers noted that the effect of air pollution on verbal ability is even more serious as people age, especially among men and the less educated. The researchers also stressed that every country, whether developed, developing or poor, should focus on air pollution or humans will face a bad situation.”可知，研究人员指出，随着人们年龄的增长，空气污染对言语能力的影响更加严重，尤其是在男性和文化程度较低的人群中。研究人员还强调，每个国家，无论是发达国家，发展中国家还是贫穷国家，都应关注空气污染否则人类将面临一个糟糕的局面。因此在最后一段中研究人员强调了全世界应该注意空气污染。故选B。

【4】推理判断题。根据第一段中的“A new study shows that air pollution can cause a huge reduction in our intelligence. The study was a project involving researchers at Peking University in China and Yale University in the United States.”可知，本文的话题是研究表明空气污染会大大降低人们的智力。该研究是一个由中国北京大学和美国耶鲁大学的研究人员参与的项目。因此可以推断出文章可能来自于科学杂志。A. A life diary一本生活日记； B. A guidebook一本指南；C. A science magazine一本科学杂志；D. A biography一部传记。故选C。
