When my first wartime Christmas came, I was in basic training in New Jersey and not sure if I would make it home for the holidays. Only on the afternoon of December 23 was the list of men who would have the three-day holiday posted. I was one of the lucky soldiers. It was Christmas Eve when I arrived home, and a little snow had fallen. Mother opened the front door. I could see beyond her, into the corner of the living room where the tree had always stood. There were lights, all colors, and ornaments (饰品) shining against the green of a pine.
"Where did it come from?" I asked.
"I asked the Gates boy to cut it," my mother said. "I wouldn't have had one just for myself, but when in great need... such a rush! He just brought it in this afternoon."
The pine reached to the proper height, almost to the ceiling, and the Tree Top Crystal（水晶） Star was in its place. A few green branches reached out a little awkwardly（难看） at the side, I thought, and there was a bit of bare trunk showing in the middle. But the tree filled the room with warm light and the whole house with the pleasant smell of Christmas.
"It's not like the one you used to find," my mother went on. "Yours were always in good shape. I suppose the Gates boy didn't know where to look for a better one. But I couldn't be fussy(挑剔的)."
"Don't worry," I told her. "It's perfect."
It wasn't, of course, but at the moment I realized something for the first time: All Christmas trees are perfect.

Doctors in Britain are warning of an obesity time bomb, when children who are already overweight grow up. So, what should we do? Exercise more? Eat less? Or both? The government feels it has to take responsibility for this expanding problem.
The cheerful Mr. Pickwick, the hero of the novel by Charles Dickens, is seen in illustrations as someone who is plump and happy. In 18th century paintings, beauty is equated （使…等同） with rounded bodies and soft curves. But nowadays being overweight is seen as indicating neither a cheerful character nor beauty but an increased risk of heart disease, stroke and diabetes.
So what do you do? Diet? Not according to England's chief medical officer, Sir Liam Donaldson. He says that physical activity is the key for reducing the risks of obesity, cancer and heart disease. And the Health Secretary John Reid even said that being inactive is as serious a risk factor in heart disease as smoking.
So, having bought some cross trainers, how much exercise should you do? According to Sir Liam Donaldson, at least 30 minutes of moderate activity five days a week. Is going to the gym the answer? Luckily for those who think that running machines are boring, the Health Development Agency believes that physical activity that fits into people's lives may be more effective. They suggest taking the stairs rather than the lift, walking up escalators, playing active games with your children, dancing or gardening. And according to a sports psychologist, Professor Biddle, gyms "are not making the nation fit", and may even cause harm.
There's new scientific evidence that too much exercise may actually be bad for you. Scientists at the University of Ulster have found that unsuitable exercise releases dangerous free radicals that can adversely （oppositely） affect normal function in unfit people. The only people who should push their bodies to that level of exercise on a regular basis are trained athletes.
So, should we forget about gyms and follow some expert's advice to reduce sedentary （久坐不动的） activities and increase exercise in our daily life? After all, getting off the bus a stop early and walking the rest of the way can't do any harm! One final thought. How come past generations lacked gym facilities but were leaner and fitter than people today?Mr.Pickwick and the paintings of the 18m century are used as examples to show that_____.
| A．beauty should be overweight |
| B．a fat man is usually a cheerful character |
| C．fatness was considered something good at one time |
| D．fatness leads to an increased risk of disease |
According to Sir Liam Donaldson, we should_____.
| A．go on a diet | B．do regular physical activity |
| C．give up smoking | D．go to the gym |
The underlined phrase cross trainers probably refers to _____.
| A．people who help you do exercise | B．places where you can do exercise |
| C．a kind of shoes | D．a form of vehicles |
At present being overweight indicates _____.
| A．an increased risk of diseases | B．a happier life |
| C．a cheerful character | D．a beauty |
What is the passage mainly about?
| A．how to keep fit and avoid fatness. | B．increased risks for overweight people. |
| C．the dangers of exercise in the gym. | D．the benefit of a balanced diet. |
No budget for your vacation? Try home exchanges ---- swapping houses with strangers. Agree to use each other’s cars, and you can save dollars on car rentals (租赁费), too.
Home exchanges are not new. At least one group, Intervac, has been facilitating such an arrangement since 1953. But trading online is gaining popularity these days, with several sites in operation, including Home Exchanges. Founded in 1992, with some 28,000 listings, this company bills itself as the world’s largest home exchange club, reporting that membership has increased 30% this year.
The annual fee is usually less than US$100. Members can access thousands of listings for apartments, villas, suburban homes and farms around the world. Initial contact is made via e-mail, with subsequent communication usually by phone. Before a match is made, potential swappers tend to discuss a lot.
However, the concept may sound risky to some people. What about theft? Damage? These are reasonable causes for concern, but equally unlikely. As one swapper puts it, “Nobody is going to fly across the ocean or drive 600 miles to come steal your TV. Besides, at the same time they’re staying in your home, you are staying in their home.”
Exchange sites recommend that swappers discuss such matters ahead of time. They may fill out an agreement spelling out who shoulders which responsibilities if a problem arises. It does not matter if the agreement would hold up in court, but it does give the exchangers a little satisfaction.
Generally, the biggest complaint among home exchangers has to do with different standards of cleanliness. Swappers are supposed to make sure their home is in order before they depart, but one person’s idea of “clean” may be more forgiving than another’s. Some owners say if they come back to a less-than-sparkling kitchen, it may be inconvenient but would not sour them on future exchanges.What is the second paragraph mainly about?
| A．How to exchange homes. |
| B．The biggest home exchange agency Intervac. |
| C．The fact that home exchanges are not new. |
| D．A contrast between Intervac and Home Exchanges. |
How do home exchangers normally begin their communication?
| A．By phone. | B．Via a matchmaker. |
| C．By e-mail. | D．Via a face-to-face meeting. |
What is recommended in the passage to deal with the concerns about theft and damage?
| A．One can file a lawsuit in court. |
| B．Both parties can trade online. |
| C．One can damage the home of the other party in return. |
| D．Both parties can sign an agreement beforehand. |
A sixth of undergraduates in Beijing this year have registered at driving school. The students, mostly from majors such as business management or international trade, will finish their driving courses within 20 days or so.
Training costs have dropped to 2, 600 yuan for students, according to the Haidian Driving School in Beijing. The price is not really low, but students will accept it, seeing it as an investment （投资）in their future. Familiarity with the operation of computers and fluent English are the basic skills graduating students need to find a job. But a driver’s permit has become another factor.
“In the job market, owning a driver’s permit sometimes strengthens a graduating student’s competitiveness for a good position, ”says Zhou Yang, an undergraduate at the China University of Political Science and Law.
Cars will become a necessary part of many people’s lives in the coming years, and it is difficult to get a permit out of campus because of the pressures on working people’s time. “Having a fulltime job after graduation offers limited time to learn to drive. We senior students have plenty of spare time, plenty of opportunity to learn. ”Zhou says.
Xu Jian, an official at the driving school, said undergraduates were very able and serious, and could grasp in an hour what ordinary people took four hours to learn. In this driving school, middle-aged people, young women and college students are the main customers.
To get a driver’s permit, a beginner is now required to have at least 86 hours’ practice before the final road test.The undergraduates are learning to drive because ________.
| A．they like to drive cars |
| B．they need this skill to find a good job |
| C．they will not have any time to learn to drive after they have found a full-time job |
| D．most of them will be able to buy cars in the future |
Which of the following is likely to be Xu Jian’s opinion of students learning to drive?
| A．It is better to learn it at college than at work. |
| B．Young people have an advantage in learning to drive. |
| C．It is a waste of money and time to learn to drive. |
| D．They will spend three times more time to learn to drive than usual. |
Which of the following can be the best headline for the passage?
| A．Students Learn to Drive. |
| B．Students Pay Less to Learn to Drive Now. |
| C．It is Better to Learn to Drive at Colleges. |
| D．Welcome to the Driving School. |
The Queen’s English is now sounding less upper-class, a scientific study of the Queen’s Christmas broadcasts has found. Researchers have studied each of her messages to the Commonwealth countries since 1952 to find out the change in her pronunciation from the noble Upper Received to the Standard Received.
Jonathan Harrington, a professor at Germany’s University of Munich, wanted to discover whether accent changes recorded over the past half century would take place within one person. “As far as I know, there just is nobody else for whom there is this sort of broadcast records,” he said.
He said the noble way of pronouncing vowels(元音) had gradually lost ground as the noble upper-class accent over the past years. “Her accent sounds slightly less noble than it did 50 years ago. But these are very, very small and slow changes that we don’t notice from year to year.”
“We may be able to relate it to changes in the social classes,” he told The Daily Telegraph, a British newspaper. “In 1952 she would have been heard saying ‘thet men in the bleck het’. Now it would be ‘that man in the black hat’. Similarly, she would have spoken of ‘the citay’ and’dutay’, rather than ‘citee’ and ‘dutee’, and ‘hame’ rather than ‘home’. In the 1950s she would have been ‘lorst’, but by the 1970s ‘lost’.”
The Queen’s broadcast is a personal message to the Commonwealth countries. Each Christmas, the 10-minute broadcast is put on TV at 3 pm in Britain as many families are recovering from their traditional turkey lunch(传统火鸡午餐).
The results were published(发表) in the Journal of Phonetics.The Queen’s broadcasts were chosen for the study mainly because .
| A．she has been Queen for many years |
| B．she has a less upper-class accent now |
| C．her speeches have been recorded for 50 years |
| D．her speeches are familiar to many people |
Which of the following is an example of a less noble accent in English?
| A．“Dutay”. | B． “Hame”. | C．“Citee”. | D．“Lorst”. |
We may infer from the text that the Journal of Phonetics is a magazine on .
| A．Christmas customs | B．speech sounds |
| C．TV broadcasting | D．personal messages |
What is the text mainly about?
| A．The changes in a person’s accent. |
| B．The Queen’s Christmas speeches on TV. |
| C．The relationship between accents and social classes. |
| D．The recent development of the English language. |
Black Box
You never see them, but they're with you every time you fly. They record where you're going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to resist almost any disaster makes them seem like something out of a comic (漫画) book.They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to the Comoros Islands in the Indian Ocean on June 30, 2009, the black box is the best method for identifying what went wrong. So when a French submarine(潜水艇) discovered its homing signal five days later, it marked a huge step toward determining the cause of the disaster in which 152 passengers were killed.
In 1958. Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first model for a black box, which became a requirement on all US commercial flights by 1960. Early models often failed to resist crashes, however, so in 1965 it was completely redesigned. That same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to be easier to see.
Modem airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help experts reconstruct the aircraft's final moments. The boxes can resist powerful force and temperatures up t0 2,OOOoF. They're also able to send out signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447 , which crashed near Brazil on June 1 , 2009 , are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.What can we leam about the black box from the passage?
| A．It helps an airplane function normally. |
| B．Its ability to avoid disasters is amazing. |
| C．It is necessary equipment on an airplane. |
| D．The idea for its design comes from a comic book. |
From the black box on the Yemeni airliner we can get information about _____.
| A．the scene of the crash and the damage |
| B．data for analyzing the cause of the crash |
| C．the total number of passengers on board |
| D．homing signals sent by the pilot before the crash |
The Federal Aviation Authority required the black boxes be painted orange or yellow to
| A．make them easily identified |
| B．meet the international standards |
| C．caution people to handle them with care |
| D．distinguish them from the color of the plane |
What do we know about the black boxes from Air France Flight 447?
| A．They have stopped sending homing signals. |
| B．They were destroyed somewhere near Brazil. |
| C．There is an urgent need for them to be restructured. |
| D．There is still a good chance of their being recovered. |
