Three Yale University professors agreed in a discussion that the automobile was what one of them called “Public Health Enemy No. 1 in this century”. Besides polluting the air and overcrowding the cities, cars are involved in more than half the disastrous accidents, and they contribute to heart disease “because we won’t walk anywhere any more,” said Richard Weeinaman, professor of medicine and public health.
Speaking of many of those man-made dangers of the automobile, Arthur W. Galson, professor of biology, said it was possible to make a kerosene-burning turbine car that would “lessensmog by a very large factor”. But he expressed doubt whether Americans were willing to give up moving about the countryside at 90 miles per hour in a large vehicle. “America seems wedded to the motor car—every family has to have at least two, and one has to be a convertible (敞篷汽车) with 300 horsepower,” professor Galson continued. “Is this the way of life that we choose because we treasure these values?”
For professor Sears, part of the blame lies with “a society that regards profit as a supreme value, under the illusion that anything that’s technically possible is, therefore, morally justified”. Professor Sears also called the country’s dependence on its modern automobiles “terrible economics” because of the large horsepower used simply “moving one individual to work”. But he admitted that Americans have painted themselves into a corner by allowing the national economy to become so dependent on the automobile industry.
“The solution,” Dr Weeinerman said, “is not finding a less dangerous fuel but a different system of inner city transportation. Because of the increasing use of cars, public transportation has been allowed to wither (衰弱) and grow worse, so that if you can’t walk to where you want to go, you have to have a car in most cities,” he declared. This, in turn, Dr Weeinerman contended, is responsible for the “arteriosclerosis (动脉硬化)” of public roads, for the pollution of the inner city and for the middle-class movement to the suburbs.The main idea of the passage is that .

The iPhone, the iPad: each of Apple’s products sounds cool and has become a fad(一时的风尚). Apple has cleverly taken advantage of the power of the letter “i” –-- and many other brands are following suit. The BBC’s iPlayer --- which allows Web users to watch TV programs on the Internet ---used the title in 2008. A lovely bear --- popular in the US and UK --- that plays music and video is called “iTeddy”. A slimmed-down version(简装本) of London’s Independent newspaper was started last week under the name “i”.
In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce(电子商务) first came into use.
Most “i” products are targeted at （针对）young people and considering the major readers of 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 the 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（定义）,” he says.
“However, thanks to Apple, the term is now connected 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(十年).
But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. However, as we entered the new century, the fashion disappeared.People use iPlayer to __________.
| A．listen to music | B．make a call |
| C．watch TV programs online | D．read newspapers |
We can infer that the Independent’s “i” is designed for _________.
| A．young readers | B．old readers |
| C．fashionable women | D．engineers |
The underlined word “ambiguous” means “__________”.
| A．popular | B．uncertain |
| C．clear | D．unique |
Nowadays, the “i” term often reminds people of the products which are __________.
| A．portable | B．environmentally friendly |
| C．advanced | D．recyclable |
The writer suggests that __________.
| A．“i” products are often of high quality |
| B．iTeddy is alive bear |
| C．the letter “b” replaces letter “i” to name the products |
| D．the popularity of “i” products may not last long |
Most people buy a lot of gifts just before Christmas. But some people think we buy too much. They have started a special day called Buy Nothing Day. They don’t want anyone to go shopping that day.
Buy Nothing Day is November 29. It’s 25 days before Christmas. It’s after Thanksgiving and often the first day of Christmas shopping. At this time, we see ads in newspapers and on TV telling us to “buy, buy, buy!”
The idea for Buy Nothing Day started in Vancouver, British Columbia. Now people all over the world celebrate Buy Nothing Day. In California, parents and children get together to read stories, sing songs, and paint pictures. The children talk about why they don’t need a lot of toys. This year, in Manchester, England, people dressed up to tell people that we buy too much.
In Albuquerque, New Mexico, high school students wanted to tell other students about Buy Nothing Day. They organized a spaghetti dinner to give people information about Buy Nothing Day. They asked restaurants in the neighborhood to donate the food. They made posters and talked to other students about it. The dinner was a big success, and many students agreed not to buy anything on November 29. The students at high school liked the idea of this new tradition. Next year, they want to have another dinner to tell more people about Buy Nothing Day!Which of the following is NOT the day for people to celebrate Buy Nothing Day?

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species. That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”The aim of “Noah’s Ark” project is to _______.
| A．make efforts to clone the endangered pandas |
| B．transfer the nuclear of one animal to another |
| C．collect DNA of endangered animals to study |
| D．save endangered animals from dying out |
According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.
| A．available panda eggs | B．host animals |

| D．about two thousand of species will probably die out in a century |
People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.
Researchers raised baby mice from birth to weaning (断奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.
Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12hour schedule, one of which joined the winter group, and one of which joined the summer group.
After 28 days, it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winterborn mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.
The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.
“We know that the biological clock regulates mood in humans，”said study researcher McMahon. “If the mechanism (机制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”How many groups of mice are there finally in all in the experiment?
| A．Seven. | B．Six. | C．Five. | D．Four. |
What's the main idea of the text?
| A．The biological clock regulates mood in humans. |
| B．People born in winter are at higher risk for physical health disorders. |
| C．The length of light will influence the behavior of the mice. |
| D．Being born in winter has a negative effect on people's mental health. |
The underlined word “split”(Paragraph 3) can be replaced by ________.
| A．ended | B．divided | C．hit | D．torn |
Who is the appropriate reader of the passage?
| A．A jobhunter. |
| B．A student in the university. |
| C．A newlymarried couple. |
