Teens don’t understand the big fuss (小题大做). As the first generation to grow up in a wired world, they hardly know a time when computers weren’t around, and they eagerly catch the chance to spend hours online, chatting with friends. So what?
But researchers nationwide are increasingly worried that teens are becoming isolated (孤寂), less skillful at person-to-person relationships , and perhaps numb (麻木) to the cheatings that are so much a part of the e-mail world . “And a teen’s sense of self and values may be changed in a world where personal connections can be limitless,” said Sherry Turkle .
Another researcher , Robert Kraut , said he’s worried about the “opportunity costs” (机会成本)of so much online time for youths . He found that teens who used computers, even just a few hours a week, showed increased signs of loneliness and social isolation. “Chatting online may be better than watching television , but it’s worse than hanging out (闲逛) with real friends,” he said .
Today’s teens, however, don’t see anything strange in the fact that the computer takes up a central place in their social lives. “School is busy and full of pressure. There’s almost no time to just hang out,” said Parker Rice, 17. “Talking online is just catch-up time.”
Teens say they feel good about what they say online or taking the time to think about a reply. Some teens admit that asking someone for a date, or breaking up, can be easier in message form, though they don’t want to do so. But they insist there’s no harm.The researchers argue that .

There was great excitement on the planet of Venus (金星) . Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan, named after the great Venusian astronomer Professor. Manhattan, who first discovered it with his telescope 20000 light years ago.
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology.
"We have come to the conclusion, based on last week's satellite landing," Prof. Zog said, "that there is no life on Earth."
"How do you know this?" the science reporter of the Venus Evening Star asked.
"For one thing, Earth's surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive."
"What does this mean as far as our flying saucer program is concerned?"
"We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned."
"Are there any other dangers that you discovered in your studies?"
"Take a look at this photo. You see this dark black cloud hovering (盘旋) over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there."
"Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer."
"If all you say is true, won't this set back the flying saucer program several years?"
"Yes, but we shall continue as soon as the Grubstart gives us the added funds(资金)." Profession. Zog replied. According to the passage, the Venusian scientists succeeded in getting important information about _____.
| A．the feasibility of landing a satellite on Earth |
| B．the possibility of making a first-rate flying saucer |
| C．the feasibility of sending a Venus Being to Earth |

In 1980，Candy Lightner’s 13-year-old daughter Cad was killed by a drunk driver as she walked down a suburban street in California. “I promised myself on the day of my daughter’s death that I would fight to make this needless accident count for something positive in the years ahead,” Candy Lightener later wrote.
The drunk driver received a two-year prison sentence. However, he avoided prison by serving time in a work camp and a halfway house. Ms. Lightner was very angry about that and so organized Mothers Against Drunk Drivers (MADD), which later changed to Mothers Against Drunk Driving. The aim of her organization was to raise public awareness of the serious nature of drunk driving and to promote tough legislation against the crime.
Before Ms. Lightner’s MADD, intoxication (醉酒), including drunk driving, was not taken seriously. Intoxication was often used as an excuse for otherwise unacceptable behavior: “I didn’t know what I was doing—I was drunk.”
Candy Lightner appeared on major television shows, spoke before the US Congress, addressed professional and business, groups, and worked tirelessly for years to change public attitudes, change judicial(审判的) behaviour, and promote tough new legislation. Ms. Lightner left MADD because the organization that she herself created is changing its focus. “I didn’t start MADD to deal with alcohol. I started MADD to deal with the issue of drunk driving.”
The President of the United States awarded her the President’s Volunteer Action Award and she was the subject of the movie “Mothers Against Drunk Drivers: the Candy Lightner Story”.One of the purposes of MADD was to______ .
| A．make the public aware of the danger of drunk driving |

which way didn’t Ms. Lightner use to achieve her MADD’s goals?
| A．Talking on major TV shows. |
| B．Giving a talk to businessmen. |

Americans use many expressions with the word dog. People in the United States love their dogs and treat them well. They take their dogs for walks, let them play outside and give them good food and medical care. However, dogs without owners to care for them lead a different kind of life. The expression, to lead a dog's life, describes a person who has an unhappy life.
Some people say we live in a dog-eat-dog world. That means many people are competing for the same things, like good jobs. They say that to be successful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog.
Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new things and will not change the way they do things.
Some people are compared to dogs in bad ways. People who are unkind or uncaring can be described as meaner than a junkyard dog. Junkyard dogs live in places where people throw away things they do not want. But mean dogs are often used to guard this property. They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad. We say his bark is worse than his bite.
Dog expressions also are used to describe the weather. The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard. We do not want it to rain cats and dogs. A person who lives an unhappy life can be described as “_______”.
| A．becoming sick as a dog | B．leading a dog’s life |
| C．living in a dog-eat-dog world | D．Working like a dog |

My interest in Chinese food started years a90, when l was a young reporter for the Washington Post. Our office wasn’t far from Chinatown, where I found some very good Chinese restaurants．
The first time I ever ate Chinese food I loved it. I noticed the fresh taste of the meat and vegetables. When I learned more about the food, I began to understand why it has this special feature.
Many years ago, China had an energy crisis because it lost much of its wood due to over population and poor management of its forests. This loss was very bad for the country, of course, but it turned out to be very good for the food. Wood became very expensive and hard to get，so the Chinese had to either find a substitute for their valuable wood，or learn how to use it better. There weren’t any substitutes so people found ways to economize.
In order to economize in cookin9, they had to use very little wood. So they started cutting their meat and vegetables into small pieces before they put them in the hot oil．That way，the food cooked faster and they saved their fuel. The food prepared in this way kept its fresh flavor一and it's this flavor that attracts people from other countries to the art of Chinese cooking. This text is mainly about________.
| A．what caused Chinese food to taste fresh |
| B．how Chinese food is cooked in the US |
| C．when the author started to make Chinese food |
| D．why most foreigners like cooking Chinese food |
The author mentioned the energy crisis to show________.
| A．it is important to protect the forests |
| B．it is necessary to find substitutes for wood |

It can be inferred from the text that before the energy crisis Chinese food________.
| A．was cooked in rather large pieces |
| B．was cooked in water but not oil |
| C．didn’t taste good |
| D．didn’t look fresh |
Jerry Morris died on 28 October 2009. He was 99 years old. You have probably never heard of him. He was a professor of public health. More than 50 years ago he produced one of the most famous epidemiological (流行病学) papers of the 20th century.
His study showed that bus conductors were much less likely to die of heart disease than bus drivers. Why? Becausethe conductors spent their working day walking. It seems obvious now but in the middle of the last century doctors were puzzled by the rising numbers of people who got heart diseases. Jerry Morris found one of the main causes: asedentary (久坐不动的) lifestyle. He started exercising for a few minutes eachday and lived until his 100th year.
If you wish to protect your heart, you have to do more than wander in the garden. The exercise needs to be reasonable. Jogging is not for everyone and a round trip to the gym takes a couple of hours, plus the monthly membership fee is only good value if you visit regularly. Theanswer is simple: walk.
A half-hour purposeful walk five times a week will lower your risk of heart disease, diabetes and strokes. Older people sometimes feel they have left it too late. But it is never too late to start and there are no upper age limits. Start gently. Take your time: a15-minute flat walk in the nearest park, four or five times a week. Within a month or so, you are already beginning to protect your heart. Build the walks up. When you can comfortably walk for half an hour in the park, go further: try following rivers and canals.
Regular walkers have their own natural gymnasium. Thereis no membership fee, just some of the finest scenery in the world. Great Britain is the walker’s gym. Whenyou have followed the rivers and canals, and are enjoying walking for a couple of hours, head for the coast. Once again, build it up slowly. When you are comfortable with long coastal walks, you can think of our national parks.Jerry Morris is mentioned in the first paragraph mainly to __________.
