★The more televisions 4-year-old children watch, the more likely they are to become bullies later on in school, a newest U.S. study said. At the same time, children whose parents read to them, take them on outings and just generally pay attention to them are less likely to become bullies, said the report from the University of Washington. Researchers also found gaps in learning and understanding such things as social skills early in life makes it more difficult for children to relate with other children. Watching violence on television leads to aggressive behavior.
★You could soon be able to add your favorite perfume to your e-mails. UK net provider Telewest Broadband is testing a system to let people send e-mails over the Internet with sweet smell. It has developed a kind of hi-tech air freshener that plugs into a PC and sprays a smell linked to the message. Telewest says it could be used by supermarkets to attract people with the smell of fresh bread or by holiday companies seeking to stir up images of sun-kissed beachers.

Anyway，I believe their presence is a good thing. Life with them seems easier, less difficult and more comfortable You can use them to choose your meal，to withdraw your money, and also save your time，because these operations are all controlled by computers. Therefore you can hardly imagine the modern world without them；the whole planet seems to be one big computer society．
Nevertheless，problems can often appear in this area, too．To have a computer means you have to be quite well－off and have the necessary skills to use it．However，think about questions like “Are computers so available for everyone, or rich and poor people，for people from villages and people from cities. Aren’t they too expensive？Is everyone able to learn how to use them and not everyone has the chance to access and work with them，how could everything in the future be dependent on them？”Therefore，I think our society will be split into two parts．One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out and will actually be far behind the other group．
Another question that bothers me is，on the one hand，computers are important and good things in our life，but they aren’t everything．They are good as a help at school，quite often as entertainment，especially for young people，as an necessary tool to help in research etc，but I think we shouldn’t be so dependent on them，because computers are only machines and machines can’t feel anything be human and sympathetic，and every action performed by computer can be interfered with another person，which could cause these machines to crash or work badly．
In conclusion，I would like to say I am not against computers．I use computers，too，but people should be wary all the time．
小题1:By saying “wary”（In the last paragraph）,the writer is trying to say “People should_______.
| A．be strongly for the use of computers because of its convenience |
| B．be careful with computers that will also cause problems |
| C．master more necessary computer skills |
| D．not do something that causes computers to work badly |
小题3: In the third paragraph，the author presents his idea by________
| A．asking questions for people to think about |
| B．giving examples to support his argument |
| C．raising questions and answering them |
| D．expressing his opinion directly |
| A．to encourage us to use computers in our society |
| B．to advise us to say no to computers from now on |
| C．to remind us to care about the problems that computers bring. |
| D．to inform us that the computer has become a necessary part of our life |
Biosphere 2, as it is called, was built not far from Tucson in 1984 and is now run by Columbia University. This huge（7,200,000-cubic-foot）glass and steel construction contains several separate ecosystems, including a desert, a rain forest, and a 900,000-gallon “ocean.” The climatic conditions-humidity, temperature, air quality-are regulated by sensors and can be adjusted as needed or desired. For example, a rainstorm can be created to increase the humidity. The adjustable features of Biosphere 2 make it an ideal location to perform experiments to help determine the effects of such climatic changes as global warming.
The current conditions at Biosphere 2 are vastly different from those in 1993, when eight people who had moved into the environment with great fanfare two years earlier moved out in failure. Though promising to be self-sufficient（自足的）, these “colonists” had so much trouble regulating the environment that they reportedly had food smuggled into them. Oxygen levels became dangerously low; most plants and animals died. In taking over the unsuccessful site, Columbia hopes to erase its notorious past by focusing on small research projects that gradually answer some of Biosphere 1’s — that is, Earth’s most basic environment questions.
小题1:This passage primarily deals with _________.
| A．conditions of life in Biosphere 2 |
| B．building controlled environments on other planets |
| C．why Biosphere 2 failed in the past |
| D．what makes a good biosphere colonist |
| A．a group of eight colonists |
| B．Columbia University |
| C．the city of Tucson |
| D．scientists who hope to establish Biosphere 3 |
| A．did not like living in a controlled environment |
| B．found it very difficult to live in a controlled environment |
| C．still are involved with Biosphere 2 |
| D．have now left the country in disgrace |
| A．comparing its features with those of an outer space biosphere |
| B．explaining the process by which it was constructed |
| C．referring to an interview with one of former inhabitants |
| D．describing its appearance and conditions |
| A．well known for something good | B．well known for something bad |
| C．very dangerous | D．quite interesting |
In the first stage of our lives, we develop and grow, reaching toward the top of physical vitality (活力,生气).
After we grow up, however, the body begins a process of gradually wearing out.
A new awareness of physical fitness may help lengthen our years of health and vitality, yet nothing we do will work to stop the unavoidable force of aging.
Most of the changes of aging take place deep inside the body. The lungs become less able to take in oxygen. Powerful muscles gradually lose their strength. The heart loses power and pumps less blood. Bones grow easier to break.
Finally, we meet a stress, a stress that is greater than our physical resistance. Often, it is only a minor accident or chance infection (a disease caused by virus), but this time, it brings life to an end.
In 1932, a classic experiment nearly doubled the lifetime of rats, simply by cutting back the calories in their diet. The reason for the effect was then unknown.
Today, at the University of California at Berkley, Dr. Paul Seagle has also greatly lengthened the normal lifetime of rats. The result was achieved through a special protein limited diet, which had a great effect on the chemistry of the brain. Seagle showed that within the brain, specific chemicals control many of the signals that influence aging. By changing that chemical balance, the clock of aging can be reset.
For the first time, the mystery of why we age is being seriously challenged. Scientists in ma
ny fields are now making striking and far-reaching discoveries.An average lifetime lasts 75 years, yet in each of us lies a potential for a longer life. If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years.

| B．physical fitness can’t stop the force of aging |
| C．human’s lifetime will last longer than 75 years |
| D．all of the changes of aging take place deep inside the body |
| A．By limiting the protein in their diet. | B．By cutting the calories in their diet. |

Some weight-loss camps, which are rare in China just a few years ago, have sprouted in Beijing, Qingdao, Shenzhen, and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight. Of these, 90 million—about 7 percent—are obese（极肥胖的）.
Experts say the obesity epidemic is spreading to children, though more slowly than in adults. The trend, they say, will have a huge impact on the health of China’s citizens and economy. “We’re seeing a very large proportion of children and adolescents who are quite heavy and aren’t moving much,” said Barry Popkin, a nutrition professor. Popkin carries out an ongoing health-and-nutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight “quite quickly.” In just ten years, China’s childhood obesity rate has doubled, with the greatest gains coming in urban areas. “In big cities it’s a big problem.”
Some experts blame the extra fat on a range of factors, many of them tied to China’s rapidly changing economy and culture. The diets of Chinese adults and children are far higher in calorie-laden meats, fish, eggs, dairy products, fats, and sugars than ever before. In addition, kids—especially city dwellers—are more sedentary today and spend more time indoors in front of homework, television, computer games, and the Internet.
Shuwen Ng, a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids’ food choices. Certain foods, such as new candies or fast food, have attractive features.
China’s childhood obesity rate still lags that of the United States, where some 15 percent of kids are said to be obese. But the long-term effects are equally serious.
小题1:According to the passage we know _____.
| A．weight-loss camps have been very popular in China six years ago |
| B．about 290 million Chinese are overweight in China in all |
| C．in China childhood obesity rate in rural areas is lower than that in major cities |
| D．America’s childhood obesity rate is lower than China’s |
| A．Advertising on some new candies | B．High quality diets |
| C．Playing computer games for long time | D．Having pocket money |
| A．attentive | B．earnest | C．absent | D．inactive |
| A．obesity explosion in China will affect the United States |
| B．there is great difference in kids’ food choices now |
| C．junk food contributes to childhood obesity |
| D．city children eat more than rural children |
| A．Chinese Childhood Obesity Explosion |
| B．Weight-loss Camps in China |
| C．Obesity Explosion’s Impacts On Chinese Economy |
| D．Obesity Explosion In China And America |
In general，single-letter prefix have been popular since the 1990s，when terms such as e-mail and e-commerce first came into use.
Most “i”products are targeted at young people and considering the major readers of the Independent’s “i”，it’s no surprise that they’ve selected this fashionable name.
But it’s hard to see what’s so special about the letter “i”.Why not use “a”，“b”or “c”instead？According to Tony Thorne，head of Language Center at King’s College，London，“i”works because its meaning has become ambiguous .When Apple uses “i”，no one knows whether it means internet，information，individual or interactive，Thorne told BBC magazines “even when Apple created the iPod，it seems it didn’t have one clear definition，”he says.
“However，thanks to Apple，the term is now associated with portability （轻便）， ”adds Thorne.
Clearly the letter “i”also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs，and we love personalized products for this reason.
Along with “Google”and “blog”，readers of BBC magazines voted “i”as one of the top 20 words that have come to define the last decade.
But as history shows，people grow tired of fads. From the 1900s to the 1990s，products with “2000”in their names became fashionable as the year was associated with all things advanced and modern. However，as we entered the new century，the trend inevitably disappeared.
小题1:
We can infer that the Independent’s “i”is aimed at _______.
| A．young readers | B．old readers | C．fashionable women | D．engineers |
