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

How has smoking been controlled in recent years?
People were asked to stop smoking in a range of public places—such as doctors’ surgeries, cinemas, theatres and churches—over the second half of the 20th century but it was after the King’s Cross Underground fire on November 18, 1987, caused by a cigarette end which resulted in 31 deaths, that restrictions on smoking in public places gained rapid and widespread acceptance.
How did a ban on smoking in public places come into place?
In 1998 the Smoking Kills White Paper set out a national strategy to reduce smoking prevalence (流行) and passive smoking, including in public places. The measures were voluntary and poorly carried out. After a public conference in England in 2004, the Government decided to choose for lawmaking. Scotland went first, with a ban in 2006, followed by the other nations a year later.
What is the current law?
Any person who smokes in enclosed public places, including pubs, offices, on public transport and work vehicles, is breaking the law. It does not extend to private houses. It is also an offence for people in charge of premises (营业场所) to permit others to smoke in them.
How was it received?
It was welcomed by most organizations—except for some pub owners and restaurateurs. Many workplaces in the UK had already introduced smoke-free policies consistent with the legislation (法律，法规) before it was carried out, while others have gone beyond its basic requirements.
All railway facilities, including platforms, footbridges and other areas—whether or not fitting the definition of an enclosed public space—are covered, as are all football grounds and some cricket and athletics stadiums. School grounds are not required to be smoke-free under the legislation, but the majority now are.
How has it been forced?
Compliance (服从) in public premises has been high, with inspections suggesting that 99 per cent of places were sticking to the rules. The number of people charged for smoking in cars has been very low, which was due to the problems defining and identifying “work” vehicles. They said that a total ban on smoking in vehicles would end this confusion.
Has it improved health?
Studies in early adopters of the law, including in Scotland, suggest a reduction in hospital admissions for heart disease, which has been shown to be linked to passive smoking. There is also strong evidence of improved rates of smoking end and a drop in the number of cigarettes consumed by those who continue to smoke.
1.When did the first law come out to ban smoking in public places?
A. 1987. B. 1998. C. 2004. D. 2006.
2.Which of the following behaviors may NOT be against the law?
A. Jack often smokes in the office when he is alone.
B. A taxi driver is smoking with a lady in his car.
C. Tom smokes while thinking of his future at home.
D. Max smokes for relaxation during time-out in the stadium.
3.Who might feel unhappy about the law according to the article?
A. A restaurant owner. B. A company manager. C. A car owner. D. A policy maker.
4.What can you infer from the article?
A. Most heart diseases have been proved to be linked to passive smoking.
B. A new law will soon come out with a total ban on smoking in vehicles.
C. The 1987 fire has convinced more people that smoking is bad for health.
D. Most of the school grounds are not smoke-free, as it is not banned in the law.

People have always had to find ways to keep food safe to eat. Methods to dry, smoke and salt food were invented thousands of years ago. 1. This storage method keeps food safe to eat for long periods of time. Today, canning is one of the most popular methods of storing food.
Clean fruits or vegetables are placed in glass bottles. The food can be put into the bottles either hot or cold. The cold method is used for soft fruits and vegetables that could lose their shape or taste. 2. They take up less space in the bottles.
After the food has been placed in glass bottles, boiling water is poured into the bottles to about three centimeters below the top. 3. The bottles are placed in a large container filled with warm water that is then brought to a boil.
The water must completely cover the bottles, from three to five centimeters over the top. When the water boils, any air in the bottles will be expelled. The boiling continues for several minutes. Then the bottles are allowed to cool. Finally, they are placed briefly into cold water. 4. In other words, a vacuum （真空）is created.
When the bottles are completely cool, notes can be placed on them to identify what is inside. The bottles can then be stored in a cool, dark place at a temperature of between 4℃ and 21℃.
5. It is also a good way to store food for six months to a year, or even several years, in case of an emergency. It does not cost much to continue canning every year once the equipment has been purchased.
A.The process of canning is much more recent.
B.This makes a strong barrier to keep the air out.
C.One popular method of canning uses a water bath.
D.Firmer fruits and most vegetables are usually cooked.
E.Canning uses heat to kill bacteria that cause poisons to form in food.
F.Then covers are placed on the bottles, but they are not turned all the way.
G.Canning allows your family to enjoy foods that might not come fresh throughout the year.

Thousands of people began pouring into Pennsylvania from other states. They wanted to buy lottery tickets. The tickets cost only $0．9 each ．But that small spending could bring them a reward of $90 million. That was the second largest lottery jackpot（积累奖金）in history.
More than 87 million tickets were bought for the Pennsylvania lottery drawing. Those who bought tickets had to choose seven numbers from 1 to 80. The chance of winning was one in 9．6 million. But that little chance certainly didn’t affect ticket sales. In the last few days before the drawing , tickets were selling at the unbelievable rate of 500 per second.
Experts say many people buy lottery tickets because they just want to have a piece of the action. Others say the lottery is a stock market for poor people. It allows them to dream about wealth they’ll probably never have.
But many people believe lotteries are no better than legalized gambling. Some critics note that most people who play are poor and may not be able to afford the tickets. There are also many addicts who take the game seriously. They may pour their life savings into lottery tickets. Some clubs have been formed to help them kick the habit.
Politicians like lotteries because they provide money that would otherwise have to some from new taxes. The profits from lotteries are usually used to pay for education or programs for senior citizens. But critics say this arrangement just allows states to legalize vice（恶习）, under the name of social progress.

In the 1920s demand for American farm products fell, as European countries began to recover from World War I and started austerity （紧缩） programs to reduce their imports．The result was a sharp drop in farm prices．This period was more disastrous for farmers than earlier times had been, because farmers were no longer self-sufficient．They were paying for machinery, seed, and fertilizer, and they were also buying consumer goods．The prices of the items farmers bought remained constant, while prices they received for their products fell．These developments were made worse by the Great Depression, which began in 1929 and extended throughout the 1939s．
In 1929, under President Herbert Hoover, the Federal Farm Board was organized．It established the principle of direct interference （干预） with supply and demand, and it represented the first national commitment to provide greater economic stability for farmers．
President Hoover's successor attached even more importance to this problem．One of the first measures proposed by President FranklinD．Roosevelt when he took office in 1933 was the Agricultural Adjustment Act, which was later passed by Congress．This law gave the Secretary of Agriculture the power to reduce production through voluntary agreements with farmers who were paid to take their land out of use．A deliberate shortage of farm products was planned in an effort to raise prices．This law was declared unconstitutional （违背宪法的） by the Supreme Court on the grounds that general taxes were being collected to pay one special group of people．However, new laws were passed immediately that achieved the same result of resting soil and providing flood-control measures, but which were based on the principle of soil conservation．The Roosevelt Administration believed that rebuilding the nation’s soil was in the national interest and was not simply a plan to help farmers at the expense of other citizens．Later the government guaranteed loans to farmers so that they could buy farm machinery, hybrid （杂交） grain, and fertilizers．
1.What caused the problem in the demand for American farm products?
A．The effect of the Great Depression．
B．The shrinking of overseas markets．
C．The destruction caused by the First World War．
D．The increased exports of European countries．
2.The word “successor” refers to ______．
A．President Hoover B．US Secretary of State
C．President Franklin D．US Secretary of Agriculture
3.The Agricultural Adjustment Act encouraged American farmers to ______．
A．reduce their scale of production
B．make full use of their land
C．adjust the prices of their farm products
D．be self-sufficient in agricultural production
4.The Supreme Court rejected the Agricultural Adjustment Act because it believed that the Act ______．
A．might cause greater shortage of farm products
B．didn't give the Secretary of Agriculture enough power
C．would benefit neither the government nor the farmers
D．benefited one group of citizens at the expense of others
