Should e-cigarettes (electronic cigarettes) be a new choice for the smokers trying to get rid of the habit? Reactions from Americans are mixed. More than half of the people questioned in a survey think e-cigarettes should be controlled by the US Food and Drug Administration, but 47 percent believe the e-cigarettes should be available to the smokers who want to quit.

“In the hunt for a safter cigarette, e-cigarettes are becoming a popular choice among those either trying to quit.”or looking to replace standard tobacco smoke with an alternative that manufacturers claim to be safer, ”Zogby International, which conducted the survey, said in a statement.

About half of the 4,611 adults who took part in the survey had heard about e-cigarettes, which are battery-powered, or rechargeable cigarettes that vaporize a liquid nicotine solution. They do not produce smoke but a water vapor without smell. Sold mostly on the Internet, e-cigarettes were first made in China.

Last year the World Health Organization (WHO) warned against using e-cigarettes, saying there was no evidence to prove they were safe or helped smokers break the habit. The WHO said people who smoke e-cigarettes breathe in a fine fog of nicotine into the lungs.

Nearly a third of people questioned in the survey think that e-cigarettes should be allowed in places where smoking is forbidden, because they don’t produce smoke, but 46 percent disagree. Men who were aware of the availability of e-cigarettes were more likely than woman to say they should be a choice available to smokers who want to quit. Young people, aged 18-29, and singles were the groups most open to trying e-cigarettes. Smoking is the single largest cause of preventable death worldwide, according to the WHO.

New research has found that young adults who smoke both tobacco cigarettes and e-cigarettes appear to have a higher risk of stroke than those who only smoke tobacco.

Carried out by researchers at George Mason University, the new study looked at 161,529 participants aged 18 to 44 years of age, who were surveyed about their cigarette and e-cigarette use.

The researchers also calculated the participants’ risk of experiencing a stroke, taking into account factors such as how much participants smoked, high blood pressure, diabetes, cholesterol levels, body mass index and physical activity levels.

The findings, published in the American Journal of Preventive Medicine, showed that the participants who smoked cigarettes and used e-cigarettes were nearly two times more likely to have a stroke compared to current cigarette — only smokers, and nearly three times more likely than non-smokers.

The team also found that participants who used only e-cigarettes had a lower risk of stroke than those who smoked only tobacco cigarettes. In fact, those who used e-cigarettes on their own did not have a significantly greater risk of stroke than non-smokers.

However, the researchers failed to find any clear benefit from switching from cigarette smoking to using e-cigarettes, even though many people believe that e-cigarettes are a “healthy” alternative to cigarettes, and a way to help smokers kick the habit. They also noted that the nicotine dependence and toxicity associated with e-cigarettes is worrying, particularly among young adults who smoke them for fun and the range of flavors.

“It’s long been known that smoking cigarettes is among the most significant risk factors for stroke. Our study shows that young smokers who also use e-cigarettes put themselves at an even greater risk,” explained lead investigator Tarang Parekh, MBBS, MSc. “This is an important message for young smokers who perceive e-cigarettes as less harmful ones and consider them a safer alternative.We have begun understanding the health impact of e-cigarettes and concomitant cigarette smoking, and it’s not good.”

“Our findings demonstrate an additive harmful effect of e-cigarettes on smokers’ blood vessels, hearts and brains,” explained Parekh.

“Consider this study as a wake-up call for young vapers, clinicians, and healthcare policymakers. There is an urgency to regulate such products to avoid economic and population heath consequences and a critical need to conduct further research on the benefits and risks of smoking cessation altermatives,” warned Parekh.

1.What does the text belong to?

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.

E-cigarettes began as a way to stop people from smoking tobacco. But a new study among teens suggests a scary effect: E-cigarettes are now appealing to non-smokers as well. In a survey of over 2 ,000 California high school juniors and seniors, researchers from the University of Southern California discovered that over 40 percent of teen e-cigarette smokers have never smoked traditional cigarettes.

The National Youth Tobacco Survey reports a nearly 9 percent increase in the number of high school students using e-cigarettes from 2013 to 2014,more than enough to stifle (掩盖) the 3. 5 percent decrease in teen cigarette use, as recorded by the Centers for Disease Control and Prevention. While 9 percent may not sound like a ton, the amount of middle and high school students using e-cigarettes has actually tripled(增至三倍) .

How, despite decades of anti-smoking advocacy efforts, have e-cigarettes gained such massive popularity in such a short time? Scientists say that the “renormalization” of teen smoking may not be entirely self-inflicted(自己造成的) .A study found that 34 percent of adolescent e-smokers are exposed to electronic cigarettes via a member of their family or friend groups.

Advertising also makes e-cigarettes look cool. E-cigarettes, which are not very expensive, are marketed as a safe alternative to traditional cigarettes, and teens are buying the message. In a recent study in North Carolina, high schoolers easily made a list of the dangers of smoking tobacco, but when asked to do the same with regard to e-cigarettes, the teens were unsure whether the devices could be considered safe. Some weren't even aware that e-cigarettes contain nicotine. But e-cigarettes do contain nicotine. It is highly addictive, which is why some consider e-cigarettes a gateway drug.

If stressing the dangers of tobacco helped make cigarettes uncool, we can do the same to destroy e-cigarettes.

1.From 2013 to 2014 student e-cigarette smokers in high school increased by about ____.

A. 3. 5%　　 B. 9%　　 C. 27%　　 D. 40%

2.About one third of teen e-smokers use e-cigarettes because of ____ .

A. e-cigarettes’ low prices　　 B. cool designs of e-cigarettes

C. the influence of people around them.　　 D. their dislike of traditional cigarettes

3.What can we infer from Paragraph 4?

A. E-cigarettes are different from drugs.

B. Teens are unsure whether e-cigarettes can be considered safe.

C. E-cigarettes are safer than traditional cigarettes.

D. Teens are misled by e-cigarette advertisements.

4.What is the author’s attitude to e-cigarettes?

A. favorable　　 B. objective　　 C. opposed　　 D. indifferent

Millions of teenagers are in danger of putting their health at risk by getting hooked on e-cigarettes, experts warn. Leading health researchers say they are “very concerned” by the growing number of youngsters trying the devices.

E­cigarettes have been marketed as a healthier alternative to smoking conventional cigarettes. But previous research shows e­cigarettes generate poisonous chemicals similar to those found in tobacco and may harm the lungs and immune system.

Worryingly, researchers at Liverpool University discovered 16% of teenagers who have used e­cigarettes had never previously smoked. The experts also found e­cigarettes were “strongly related” to drinking among teenagers. Study author Prof. Mark Bellis said, “Our research suggests that we should be very concerned about teenagers accessing e­cigarettes. While debate on e­cigarettes has focused largely on whether or not they act as a gateway to tobacco cigarette use, e­cigarettes themselves contain a highly addictive drug that may have more serious and longer lasting impacts on children because their brains are still developing.”

Researchers surveyed 16,000 students aged 14 to 17 in the North West of England and asked them about their alcohol and tobacco use. They found that one in five answered yes to the question: “Have you ever bought or tried electronic cigarettes?” More males than females said they had.

Of the teenagers that had accessed e­cigarettes, 16% had never smoked, 23% had tried smoking, 12% only smoked when drinking, and 14% were ex­smokers. The research also found teenagers who drank alcohol were significantly more likely to have accessed e­cigarettes than non­drinkers.

Among those who had never smoked, it was found that those who regularly have excessive(过多的)drinking were four times more likely to access e­cigarettes than those who never drink. In all of those that drink, regardless of smoking status, e­cigarette access was associated with excessive drinking and involvement with violence after drinking. The researchers said their findings suggest that teenagers who use e­cigarettes are most susceptible to other forms of substance use and risk­taking behaviors.

1.How have e­cigarettes been promoted in the market?

A. As a healthier substitute for traditional cigarettes.

B. As a device meeting the mental needs of smokers.

C. As a product preventing smokers from using tobacco products.

D. As a new device promoted among youngsters.

2.What do we learn from the survey made in the North West of England?

A. E-cigarettes are now widely available and heavily promoted.

B. E­cigarette access is linked to excessive drinking and violence after it.

C. Teenagers are very knowledgeable about alcohol and tobacco use.

D. The number of adult cigarette smokers is dropping at present.

3.Which of the following can replace the underlined words “susceptible to” in the last paragraph?

A. greatly interested in

B. commonly accustomed to

C. deeply disappointed at

D. easily influenced by

4.What's the main idea of the passage?

A. Experts are concerned about excessive drinking in teenagers.

B. The harm of the e­cigarettes is greater than that of alcohol.

C. Teenagers are in danger of risking their health on e­cigarettes.

D. Researchers are aware of smoke­related health harm.

Britain Supports E-Cigarettes, US Considers Ban

The United States and Britain have very different views on e-cigarettes.

American public health officials are warning of the dangers of vaping(吸电子烟)among young people. But, British officials consider electronic cigarettes to be a powerful tool for people trying to quit smoking.

Britain’s Royal College of Physicians tells doctors to promote e-cigarettes “as widely as possible” for patients trying to give up cigarettes. And Public Health England says vaping is much less dangerous than smoking.

In the United States, hundreds of people who vape have been sickened by a mysterious lung illness. Many of them are teenagers.

In answer, the federal government and some states have recently taken steps to ban the flavored e-cigarettes that appeal to young people.

The U.S. Centers for Disease Control and Prevention (CDC) now recommends that people consider not using e-cigarettes.

Dr. John Britton is director of the U.K. Center for Tobacco and Alcohol Studies at the University of Nottingham. He said the U.S. reaction is “complete madness.” Dr. Britton added, “The reality with smoking is, if you tell people to stop vaping, they will go back to tobacco and tobacco kills.”

Around the world, countries have different views on vaping. More than 30 nations ban e-cigarettes completely. Many European countries, including Austria, Belgium, Germany and Italy, consider e-cigarettes the same as tobacco products and control the sales of them.

However, France, just like Britain, hardly sets limits on the sales of e-cigarettes. In those countries, e-cigarettes are sold as usual consumer products.

E-cigarettes arrived in the United States in 2007 and have been mostly unregulated. Three years ago, the U.S. Food and Drug Administration (FDA) got the power to oversee their use. Black market, illegal sales of e-cigarettes have grown quickly.

The FDA’s acting commissioner, Dr. Ned Sharpless, recently testified(作证)before Congress.

Several lawmakers suggested complete removal of e-cigarettes from the market.

“We do not consider these products safe, we think they have harm,” Dr. Sharpless said. “We do not think really anyone should be using them other than people using them in place of smoking regular tobacco cigarettes. “

How do e-cigarettes work? The vaping devices usually heat a solution(溶液)containing nicotine into a vapor, which is inhaled. The amount of nicotine differs widely. Some countries restrict the amount. There is no limit in the United States. But the widespread use of vaping devices among young people brought warnings from health officials. They said nicotine harms a teenager’s still-developing brain.

“What’s right for England might not be right for the U.S.,” said Ryan Kennedy. He is with the Institute for Global Tobacco Control at Johns Hopkins Bloomberg School of Public Health.

The CDC said that the mysterious lung illness appears to be in connection with THC vaping products. THC is a chemical compound that gives marijuana its high.

The agency said many of the 800 people who got sick reported vaping THC. It said it still needed more information to know whether a single product, substance or brand is responsible. Some researchers have blamed an ingredient used in vaping oils, especially in black market products.
