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．

One pioneer, in particular, who disagrees is David Tebbutt, the founder of Computertown UK. Although many people see this as a successful attempt to bring people closer to the computer. David does not see it that way. He says that Computertown UK was formed for just the opposite reason, to bring computers to people and make them “people-literate.” David Tebbutt thinks Computertowns are most successful when tied to a computer club but he insists there is an important difference between the two. The clubs are for people who have some computer knowledge already. This frightens away non-experts, who are happier going to Computertowns where there are computers for them to experiment on, with experts to encourage them and answer any questions they have. They are not told what to do, they find out.The computer experts have to learn not to tell people about computers, but have to be able to answer all questions people ask. People don’t have to learn computer terms(术语), but the experts have to explain in plain language. The computers are becoming “people-literate.”
小题1:Which of the following is David Tebbutt’s ides on the relationship between people and computers?
| A．Computer learning should be made easier. |
| B．There should be more computer clubs for experts. |
| C．People should work harder to master computer use. |
| D．Computers should be made cheaper so that people can afford them. |
| A．being able to afford a computer |
| B．being able to write computer programs |
| C．working with the computer and finding out its value |
| D．understanding the computer and knowing how to use it |
| A．help to set up more computer clubs |
| B．bring people to learn to use computers |
| C．bring more experts to work together |
| D．help to sell computers to the public |
| A．making better use of computer expert |
| B．improving computer programs |
| C．increasing omputersales |
| D．popularising computers |
Doris Leuthard, the Swiss energy minister, said Switzerland would put off plans to build nuclear plants. She said no new ones would be permitted until experts had reviewed safety standards.
Germany will put off “the recently decided extension of the running time of German nuclear plants,” Chancellor Angela Merkel told reporters. “This moratorium（延缓）will run for three months and it will allow for a thorough examination of the safety standards of the county’s 17 nuclear power plants.
The European Union called for a meeting on Tuesday of nuclear safety authorities to assess Europe’s preparedness.
Germany’s foreign minister, Guido Westerwelle, called for a new risk analysis of the country’s nuclear plants, particularly regarding their cooling systems. He is the leader of the Free Democratic Party, which strongly supports nuclear power.
A previous government, led by the Social Democrats, passed a law in 2001 to close all the country’s nuclear plants by 2021. But Mrs. Merkel’s government changed that decision last year to extend the lives of the plants by an average of 12 years.
In Switzerland, Doris Leuthard said she had already asked to analyze the exact cause of the problems in Japan and draw up new or tougher safety standards “particularly in terms of seismic(地震的) safety and cooling.”
In Russia, the Prime Minister said his government would “draw conclusions from what’s going on in Japan.”
小题1:Where can you most likely read this passage?

| B．Germany will hold a meeting of nuclear safety authorities. |
| C．Germany will change the decision made last year. |
| D．Germany will delay the extension of nuclear plants running time. |
| A．The moratorium in Germany will give time to examine the nuclear plants safety standards. |
| B．Switzerland will not build new nuclear plants unless they meet the experts’ safety standards. |
| C．The Social Democrats in Germany shares the same view with the Free Democratic Party. |
| D．Russia will try to learn something from the nuclear power crisis in Japan. |
| A．Watch Out for the Danger of Nuclear Power |
| B．Europe Is against Building Nuclear Plants |

“At first we thought that only the young who really keep up with the latest technology would be interested, but we were wrong,” said Stefan Sewoester from IT Werke. “Almost two-thirds of the people who use the system are 40 and older,” he said.
IT Werke, a computer company, is one of the pioneers of fingerprint payment software in Germany. It has helped about 150 shops, canteens and bars to put in the fingerprint scanning machines. Each costs about 2,000 euros.
To sign up for the service, customers must have their fingerprints taken and leave their addresses and banking details with the shop. The shop then takes the cost of goods directly out of the customer’s bank account.
“It is especially a good thing for elderly people. Now they do not have to remember their pin to pay with their bank cards, or to scratch around for their glasses or cash.” Sewoester said.
The stores benefit from the system too. It saves more than time in the check-out line. It also cuts out the hidden costs of accepting electronic card payments.
小题1:According to the passage, the fingerprint system______.
| A．was invented by the Edeka supermarket chain |
| B．has caused payment revolution in Germany |
| C．is more popular with young people |
| D．is preferred by most American customers |
| A．have their fingerprints taken |
| B．leave their addresses |
| C．give the shop information about the bank accounts |
| D．have their phones connected with computers |
| A．They will spend less time on shopping.. |
| B．They are not forgetful. |
| C．They don’t like to pay in cash |
| D．They always fail to find their bank cards. |
“I’ve never met a human worth cloning,” says cloning expert Mark Westhusin from his lab at Texas A&M University. “It’s a stupid endeavor.”
That’s an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two cows and a cat.
They just might succeed in cloning Missy soon — or perhaps not for another five years.
Westhusin"s experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog"s eggs, the A&M team has produced only a dozen or so embryos carrying Missy"s DNA. None have survived the transfer to a surrogate（代孕的）mother. The wastage of eggs and the many spontaneously aborted(流产，发育不全) fetuses（胎）may be acceptable when you"re dealing with cats or bulls, he argues, but not with humans. “Cloning is incredibly inefficient, and also dangerous,” he says.
Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1997, Westhusin"s phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. “A lot of people want to clone pets, especially if the price is right,” says Westhusin. Cost is no obstacle for Missy"s mysterious billionaire owner; he"s put up $3.7 million so far to fund A&M"s research.
Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy"s fine qualities after she does die. The prototype（原型；雏形）is, by all accounts, athletic, good-natured and supersmart. Missy"s master does not expect an exact copy of her. He knows her clone may not have her temperament（气质、性情）. In a statement of purpose, Missy"s owner and the A&M team say they are “both looking forward to studying the ways that her clones differ from Missy.”
Besides cloning a great dog, the project may contribute insight into the old question of nature vs. nurture. It could also lead to the cloning of special rescue dogs and many endangered animals.
However, Westhusin is cautious about his work. He knows that even if he gets a dog pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems~ “Why would you ever want to clone humans,” Westhusin asks, “when we"re not even close to getting it worked out in animals yet?”
小题1:By “stupid endeavor”, Westhusin means to say that ________.
| A．human cloning is a foolish undertaking |
| B．animal cloning is absolutely impractical |
| C．human cloning should be done selectively |
| D．animal cloning is not worth the effort at all |
| A．Its success is already in sight. |
| B．It is progressing smoothly. |
| C．It is doomed to utter failure. |
| D．Its outcome remains uncertain. |
| A．study the possibility of cloning humans |
| B．search for ways to modify its temperament |
| C．find out the differences between Missy and its clones |
| D．examine the reproductive system of the dog species |
| A．a bad temper |
| B．defective（有缺陷的、有毛病的）organs |
| C．immune deficiency |
| D．an abnormal shape |
