Question

【題目】 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 (吸一口煙) 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】

這是一篇說明文。文章提到一項新的研究發(fā)現電子香煙和煙草制品一樣會導致肺部疾病，研究中還顯示電子煙使用者肺部某種蛋白質水平的升高會使患者難以呼吸。而政府暫時并沒有對電子煙消費這件事情進行監(jiān)管。

【1】推理判斷題。文章第一段提到研究人員發(fā)現電子香煙可能會導致肺部疾病，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年期間，使用電子煙的致病率猛增了900%，由此判斷出為什么FDA要將電子煙列入監(jiān)控產品是因為它意識到了它們的危害。故選A。

【2】細節(jié)理解題。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.”研究顯示使用電子香煙的人氣道中的與NET相關的蛋白質水平升高，這種水平的升高會導致肺部疾病，使患者難以呼吸。故選C。

【3】推理判斷題。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認為沒有人會警告電子煙對肺部造成的危害，而且最后一句提到“The problem is that our government just stands there with its hands behind the back.”現在政府的問題就是雙手背在身后站在那里，而不是去解決這個問題，由此判斷出，Dyclna認為政府應該對電子煙的消費負責。故選D。

【4】主旨大意題。分析文章內容可知，第一段提到新的研究整明電子香煙也會和傳統(tǒng)煙草制品一樣造成肺部疾病，第一段最后一句是該段的中心句：電子香煙并不是傳統(tǒng)香煙的完美替代。在文中接下來幾段內容提到了電子煙造成肺部疾病的致病原因，第四段的最后一句提到因為電子煙自身的風險，挑戰(zhàn)了電子煙是一種更健康的選擇這一概念，最后一段則提到了政府暫時并沒有對電子煙消費這件事情進行監(jiān)管，綜上分析，全文在表達對電子煙是傳統(tǒng)煙草制品完美替代物這一概念的質疑。所以短文的最佳標題為“電子煙是傳統(tǒng)煙草制品完美替代物？”故選B。
