Vending machines (投币式自动售货机) are found in 16% of U.S.elementary schools, 52% of middle schools and 88% of high schools.About 22% of students in grades 1 through 12 buy food in vending machines each day—and those purchases added an average of 253 calories to their diets, according to a new study in the September issue of the Journal of School Health.

Just to be clear, those were not 253 calories' worth of tofu, yogurt or carrot.The most popular vending machine items included soft drinks, candy, chips, crackers, cookies, cakes and ice cream.On the plus side (好的方面), kids also bought low-fat milk, fruit juice and even fruit, the study found.

But the eventual effect on kids' diets was not good.Those who bought from vending machines ate an average of 156 grams of sugar per day, compared with 146 grams for those who abstained (节制).They also consumed less fiber, iron and vitamin B.

One silver lining: Vending machine customers ate 4% less sodium (钠) than other students--an average of 3,287 milligrams per day compared with 3,436 mg for those who didn't buy from vending machines.That's probably because the extra snacks made kids too full to eat as much at mealtimes, when dishes are especially Salty.In any event, kids should eat no more than 1,200 to 1,500 mg of sodium each day, according to the Mayo Clinic.Even for adults, the government recommends a daily limit of 2,300 mg.

Overall, vending machines in school appear to be a threat to children's health.The researchers calculated that all that snacking adds up to about14 extra pounds per child per school year.For some students this might be a serious contributor to weight issues.The study was based on data collected from 2,309 children nationwide for the third School Nutrition Dietary Assessment Study, which was

conducted by the U.S.Department of Agriculture's Food and Nutrition Service.

1.The students using vending machines take in less of all the following EXCEPT .

2.The underlined words “One silver lining” mean “       ”.

Japan's 24-hour convenience stores, already struggling with lagging sales and growth, may soon face yet another threat - moves to limit business hours and close the stores late at night. The district of Saitama, which borders Tokyo, may follow in the footsteps of the western city of Kyoto and urge convenience stores to close during late night hours in an effort to limit carbon dioxide(二氧化碳)emissions, Japanese media reported.

 Kyoto, a former capital, wants to persuade convenience and other 24-hour stores to close late at night so as to improve evening views of the city and cut down on energy use. The Nikkei business daily said closures could last from 11 p.m. to 7 a.m. The move is strongly opposed by the industry, which fears a bad impact on an already troubled sector also grappling with the specter of a higher tobacco tax, which could hit overall sales.

 "Even if we only operate the stores for 16 hours, we can't stop the refrigerators," said Toshiro Yamaguchi, the president of Seven-Eleven Japan Co, which is owned by Seven & I Holdings Co Ltd, at a news conference in Saitama on Tuesday. He said such cuts in operating hours would reduce each store's profit by 20 percent. "If this happens, our current business model will lose its foundation."

 Analysts said that while it is difficult to estimate the potential impact of the move without a concrete plan, their overall impression was that it was likely to be negative. "This could cut profits and lead to less efficient operations and the increased loss of opportunities," said Masafumi Shoda, an analyst at Nomura Securities. "But it depends on the store -- urban stores do better than others. There are some in the countryside that are inefficient."

 Some have suggested that if governments were sincere about reducing carbon emissions there were much more efficient methods, such as cutting back on the huge number of automatic vending machines(自动售货机)

Which of the followings was the first to try to limit convenience store hours?

 A. Saitama           B. Tokyo C. Kyoto D. Nomura Security

What's the main goal of the proposal?

  A. To give employees more free time.

  B. To limit carbon dioxide emissions.

  C. To sell more tobacco products.

  D. To reduce each store’s profit.

How's the convenience store sector doing in Japan?

 A. It is not mentioned.    B. It's doing great. Business is booming.

 C. Not very well.        D. It’s about to close.

According to the passage, which convenience stores are generally more successful?

 A. The ones in big cities.     B. The ones in the countryside.

 C. The ones in Tokyo.       D. The ones in Saitama.

According to the convenience store industry, what impact would closing for the night have on a typical store?

  A. It could cause a 10% increase in sales.

  B. Its effect would be maximal. It would close soon.

  C. Its effect would be minimal. People would simply shop earlier.

  D. It could cause a 20% decrease in profits.
