Question

【题目】 E-cigarettes lead to as many lung diseases as tobacco products, a new study has found. The report from the University of North Carolina at Chapel Hill compared saliva (唾液) samples from tobacco smokers, e-cigarette smokers and nonsmokers. Researchers found that e-cigarette smokers were likely to develop dangerous proteins associated with lung diseases. The study adds to a growing body of evidence proving that e-cigarettes might not be the perfect alternative smokers addicted to tobacco are looking for.

Last year a Surgeon General’s report claimed that the use of e-cigarettes among a certain group of people jumped 900 percent from 2011 to 2015 and more studies were carried out to research their side effects. That same year, the FDA put e-cigarettes in the tobacco products the administration monitors.

Previous research from UCLA has proven that e-cigarettes can cause lifelong damage to one’s heart, and that one puff (吸一口烟) of an e-cigarette is all it takes to increase one’s risk of having a heart attack. For the new study UNC researchers observed 15 e-cigarette users, 14 cigarette smokers and 15 nonsmokers. The study revealed that e-cigarette smokers have raised levels of NET-related proteins in their airways, the increased levels of which can lead to lung illnesses, making it difficult for patients to breathe.

Study author Dr Mehmet Keismer said, “There is confusion about whether e-cigarettes are ‘safer’ than cigarettes because the potential adverse effects of e-cigarettes are only beginning to be studied. Our results suggest that e-cigarettes might be just as bad as cigarettes.” Dr Keismer also stressed that e-cigarettes come with their own harmful risks along with those linked to tobacco, which challenges the concept that switching from cigarettes to e-cigarettes is a healthier alternative.

A citizen named Dyclna said, “The e-cigarettes probably make you cough less, but nobody gives a warning about your lungs. For producers, it’s just a money thing — it’s just about getting profits from it. The problem is that our government just stands there with its hands behind the back.”

【1】Why did the FDA list e-cigarettes into monitored products?

A.It might realize the harm of them.

B.It wanted to improve their quality.

C.It aimed to reduce their illegal sales.

D.It might be warned by the government.

【2】What harm does the increased level of NET do to people?

A.Leading to weight gain.B.Spoiling people’s appetite.

C.Making breathing hard.D.Speeding people’s heartbeat.

【3】What does Dyclna mainly want to express?

A.E-cigarettes are safer than regular ones.

B.E-cigarettes can only benefit few people.

C.Producers make a high profit from e-cigarettes.

D.Governments are to blame for e-cigarettes’ consumption.

【4】What is the best title for the text?

A.E-cigarettes: A new way of smoking.

B.E-cigarettes: A better way than tobacco?

C.E-cigarettes: The harmful proteins it produces.

D.E-cigarettes: The urgent need of government control.

Answer 1

【答案】

【1】A

【2】C

【3】D

【4】B

【解析】

这是一篇说明文。文章提到一项新的研究发现电子香烟和烟草制品一样会导致肺部疾病，研究中还显示电子烟使用者肺部某种蛋白质水平的升高会使患者难以呼吸。而政府暂时并没有对电子烟消费这件事情进行监管。

【1】推理判断题。文章第一段提到研究人员发现电子香烟可能会导致肺部疾病，且第二段第一句提到“Last year a Surgeon General’s report claimed that the use of e-cigarettes among a certain group of people jumped 900 percent from 2011 to 2015 and more studies were carried out to research their side effects.”在2011年到2015年期间，使用电子烟的致病率猛增了900%，由此判断出为什么FDA要将电子烟列入监控产品是因为它意识到了它们的危害。故选A。

【2】细节理解题。第三段最后一句提到“The study revealed that e-cigarette smokers have raised levels of NET-related proteins in their airways, the increased levels of which can lead to lung illnesses, making it difficult for patients to breathe.”研究显示使用电子香烟的人气道中的与NET相关的蛋白质水平升高，这种水平的升高会导致肺部疾病，使患者难以呼吸。故选C。

【3】推理判断题。最后一段第一句提到“The e-cigarettes probably make you cough less, but nobody gives a warning about your lungs.”Dyclna认为没有人会警告电子烟对肺部造成的危害，而且最后一句提到“The problem is that our government just stands there with its hands behind the back.”现在政府的问题就是双手背在身后站在那里，而不是去解决这个问题，由此判断出，Dyclna认为政府应该对电子烟的消费负责。故选D。

【4】主旨大意题。分析文章内容可知，第一段提到新的研究整明电子香烟也会和传统烟草制品一样造成肺部疾病，第一段最后一句是该段的中心句：电子香烟并不是传统香烟的完美替代。在文中接下来几段内容提到了电子烟造成肺部疾病的致病原因，第四段的最后一句提到因为电子烟自身的风险，挑战了电子烟是一种更健康的选择这一概念，最后一段则提到了政府暂时并没有对电子烟消费这件事情进行监管，综上分析，全文在表达对电子烟是传统烟草制品完美替代物这一概念的质疑。所以短文的最佳标题为“电子烟是传统烟草制品完美替代物？”故选B。
