We know that cigarette smoking kills. So, producers made electronic cigarettes as a safer smoking choice ---- safer than tobacco. Although e-cigarettes contain the drug nicotine like cigarettes, they do not use tobacco and you do not light them. They are powered by battery.

However, if e-cigarettes are so safe, why has the United States Center for Disease Control(CDC)seen an increase in telephone calls about e-cigarette poisonings?

The answer is children. Most of the calls are from people worried about children who have played with the devices. In the period of one month this year, the Center said 215 people called the Center with e-cigarette concerns. More than half of these calls were for children aged five and younger. The devices had made them sick.

Tim McAfee is director of the Center's Office on Smoking and Health. He says the problem is regulation, meaning, the U. S. federal government does not control e-cigarettes even though they contain liquid nicotine. Mr. McAfee adds that liquid nicotine is a well-known danger. Mr. McAfee explains that nicotine poisoning happens when it gets into the skin, gets into the eyes or is swallowed. It can cause stomach pain or a sense of unbalance. And too much nicotine can kill.

Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do. He notes that almost 500,000 Americans die each year from cigarettes. "So, cigarettes are the winner in that contest." E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes. So, the U. S. Surgeon General Boris D. Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use.

But McAfee worries that teenagers may think electronic cigarettes are harmless. They could become addicted to the nicotine and then start smoking real cigarettes. In other words, he fears that for young people fake e-cigarettes could be a "gateway" to the real thing.

1.What do the producers think of e-cigarettes?

A. Dangerous. B. Expensive.

C. Safer. D. Cheaper.

2.Why did the CDC receive so many calls about e-cigarettes?

A. Parents feared that their children might get poisoned.

The Happiest Cities On Earth

If you’re looking for a cheery destination for your next vacation, consider these four spots and get ready to take notes on how to really live the good life.

Singapore

With one of the highest population densities(密度)in the world and residents known for being workaholics, it’s hard to imagine the city-state of Singapore having one of the happiest populations on earth.And yet in a recent survey, 95% of them said they were either very happy or quite happy.

They give their city high marks for cleanliness and safety—subways are pristine(洁净的)and unfailingly arrive on time, and police are seen as helpful and good at their jobs.What’s more, they feel they can count on their neighbours—all 5.1 million of them.

Arhus, Denmark

The residents of Arhus cheerfully part with 68% of their income in taxes, knowing that in return they will be guaranteed free healthcare, free daycare, and a top-notch(第一流的)education for their children.

An energetic city of 300,000 with a lively cultural scene and a diverse number of religions represented, the sense of equality(the range in incomes is narrow), as well as easy access to the nearby sea and surrounding countryside, make Arhus seem more like a small town.

San Luis Obispo, CA

According to a 2008 Gallup-Healthways study, people who live in San Luis Obispo are more likely than residents of other U.S.cities to smile and experience joy and are less likely to experience pain or depression.About 64,000 of the 260,000 people in the greater metropolitan area(都市区), located halfway between Los Angeles and San Francisco, volunteer at over 11,000 non-profit organizations.

Few journeys to work are longer than 10 minutes (one reason its members rank in the upper third for job satisfaction), so “it’s easy to be involved,” resident Pierre Rademaker said.Business signs are unobtrusive(不显眼的)by law, fewer than 11% of residents smoke—the lower rate in the U.S.—there are lots of bike lanes, and the city’s plaza draws crowds of people for free concerts on summer Fridays.What’s not to love?

Monterrey, Mexico

The people of Monterrey don’t enjoy high household incomes or access to good healthcare.Instead, there’s a profound sense of gratitude for the new political freedom enjoyed since the oppressive Institutional Revolutionary Party lost power in 2000—the first time in nearly a century—as well as an emphasis on social life over work.

Another reason Monterrey residents may be so happy is their faith in God and family, and their ability to tough it out through bad times.

“We laugh at sickness, poverty and even death,” says Basanez, a political scientist who lives in Monterrey.“We even have a holiday to celebrate death.November 2, the Day of the Dead, is one of the biggest holidays of the year.”

1.According to the passage, what do the residents in the four cities have in common?

A.All the residents can make great fortunes by working hard.

C.All the residents enjoy enough material wealth.

D.The majority of the residents are satisfied with their current life.

A.the people of Singapore expect their neighbours to come to their help when necessary

B.the people of Monterrey even observe one’s death on a special day of a year

C.the residents of Arhus happily pay 68% of their income for their children’s education fee

B.Arhus is considered as a family sharing everything with each other.

C.There is no wide gap between the rich and the poor in Arhus.

D.The residents of Arhus can depend on their neighbours to help.

“We get up at 7:30 in the morning.Then we have breakfast.Usually we have porridge for breakfast.There is always tea, coffee, bread and pies.After breakfast, we head for a bus stop and get on a bus which runs to the media center.It takes us 30 minutes to get there,” she said.

When volunteers arrived there, they went through the security (安全) check point.They couldn’t bring water or food with them.“Security guards check our bags.We are not allowed to have things made of metals.They check phones, video cameras, electric equipment and computers,” Oksana added.

In the evening volunteers got back to the apartment buildings.All of them were like one big family.They lived together and got some rest together—after dinner they went to the beach to watch the sunset.
