Compared to people with bad attitudes，people who are cheerful and relaxed are less likely to suffer from colds，according to a new study.“It’s possible that being upbeat helps the body fight illnesses，” says Sheldon Cohen，the study’s lead researcher from Carnegie Mellon University (CMU) in Pittsburgh.

In a previous（先前的） study，Cohen and his colleagues put cold­causing viruses into the noses of 334 healthy adults. People who tended to be cheerful and lively were least likely to develop sniffles，coughs，and other cold symptoms. People who showed positive feelings were also less likely to mention symptoms to their doctors，even when medical tests detected those symptoms.

Those findings were interesting，but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead，it was still possible that a person’s underlying personality is what matters. Evidence suggests，for instance，that certain people are naturally more likely to be outgoing and optimistic，with high self­esteem and a sense of control over life. This would mean that who we are，not how we feel，ultimately decides our chances of catching colds.

To figure out which mattered more (personality or emotions)，the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. At the end of the interviewing period，people got nose drops that contained either cold or flu viruses. Then，each person stayed in an isolated room for 5 or 6 days. The results showed that everyone in the study was equally likely to get infected. Their symptoms，however，differed depending on the types of emotions that they had reported over the previous 2 weeks. Among those who reported good moods and had been infected with the flu virus，for example,28 percent developed coughs and stuffy noses. On the other hand，those symptoms struck 41 percent of people who had been less upbeat.

Benjamin Franklin only studied in school for two years. But he liked to read and write very much. Once he discussed a question with his friend in letters. His father found the letters and read them. He felt Ben did not express himself well. Nor did Ben make his meaning clear. He agreed that his father was right, From then on, he paid more attention to the style of his writing so that he could write better.

About that time he bought a copy of the British periodical(周刊) called The Spectator (《觀察家》). He read it over and over. He thought the writing excellent, and wished, if possible, to write in the same style.

With this in mind, he studied some of the stories and made a note of the thought in each sentence. Then, a few days later, without looking at the magazine, he tried to write the stories. He tried to express each thought as fully as it had been expressed before. Then he compared his writing with the magazine. He found some of his faults in the compositions.

In this way he discovered he needed to know many more words. He felt that writing poetry would help him since that needed to use many different words which had the same meaning. So he turned some of the stories into poems; and after a time, he wrote them as stories again. He insisted on doing this for a long time.

He learned much from his efforts and went on to practise his writing. Then he became the first famous writer in American history.

Is it time to kick Russia out of the BRICs （金磚四國）? If so, it may end up sounding like a famous ball-point pen maker-BIC. An argument is being made that Goldman Sach’s famous marketing device（策略）,the BRICs, should really be the BICs.

“Is Russia really worth the name BRICs?” asks Anders Aslund, senior fellow at the Peterson Institute for International Economics, in an article for Foreigh Policy. Aslund, who is also co-author with Andrew Kuchins of “The Russian Balance Sheet”, thinks the Russia of Putin and Medvedev is just not worthy of inclusion alongside Brazil, India and China in the list of future economic powerhouses. He writes:

“The country’s economic performance has fallen to such a weak level that one must ask whether it has any say at all on the global economy, compared with the other members of its group. I have just returned from Moscow, which is always dull around this season. For the last seven years, Russia has taken very few measures to improve its economy. Instead, the state has been living on oil and gas. ”

Economically, Aslund has the numbers on his side. The International Monetary Fund figures that the Russian economy will fall by 6.7 percent in 2009, while China will grow 8.5 percent and India 5.4 percent. There is less of a case for Brazil, with a fall of 0.7 percent, but it is still doing

far better than Russia.

But the BRICs are not just about economy. As is mentioned above, it is a marketing device to encourage investors to focus on the big promising players. From an investment standpoint, it could be argued that Russia is leading the BRICs. Its stock（股票）market is up 128 percent this year while around 80 percent is for the other three.

At very least, however, Russia’s economic underperformance and stock market outperfoumance does suggest it is indeed one of the group.

1.According to the passage, which country will enjoy the biggest increase in 2009?

A．China.

B．Russia.

C．Brazil.

D．India.

2.According to Aslund, Russia shouldn’t be a BRIC partly because_______.

A．Russia’s economic performance is far worse than the other three

B．Russia’s leaders are not good at managing economy

C．Russia has taken effective measures to improve its economy

D．Russia will no longer attract investors from other countries

3.From the passage we know that ________.

A．Anders Aslund is working for the Russian government

B．Russia outperfoumed the other three countries in stock market

C．most people disagree Russia is included in BRICs

D．the BRICs would end up being the BICs sooner or later

4.The author seems to ________.

A．suggest it’s time to kick Russia out of the BRICs?

B．feel worried about the economy of the BRICs

C．think Russia is worth being one of the group

D．show disappointment to Russia’s economy

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image (印象) of unhappy teenagers locked in their room after endless family quarrels.

An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. “We were surprised by just how positive today’s young people seen to be about their families,” said one member of the research team. “They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds: they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation(商議) and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”

So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends.” My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall. “I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”

Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenager rebellion is not rooted in real facts. A researcher comments, “Our surprise that teenagers say they get along well with their parents comes because of a brief period in out social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”

1. What is the popular images of teenagers today?

A．They worry about school

B．They dislike living with their parents

C．They have to be locked in to avoid troubles

D．They quarrel a lot with other family members

2.The study shows that teenagers don’t want to ___

A．share family responsibility

B．cause trouble in their families

C．go boating with their family

D．make family decisions

3.Compared with parents of 30 years age, today’s parents___.

A．go to clubs more often with their children

B．a(chǎn)re much stricter with their children

C．care less about their children’s life

D．give their children more freedom

4. According to the author, teenage rebellion____.

A．may be a false belief

B．is common nowadays

C．existed only in the 1960s

D．resulted from changes in families

 About 1 million adult New Yorkers are obese(肥胖的), but nearly two-thirds of them don’t think they are, according to a study released on Tuesday by the city’s Department of Health and Mental Hygiene(衛(wèi)生).

    Among the obese, who account for about one in five New Yorkers, only 39% described themselves as “very overweight”, according to the report. 2% said they were very underweight, 1% said they were slightly underweight, 16% said they were just right and 42% said they were slightly over weight.

     Some 2 million more New Yorkers are overweight, the report said, and one in five children in kindergarten is obese.

     Only 44% of the city’s adults are at a healthy weight, and nearly 75% say they do not participate in(參加) any regular physical activity.

     New York City’s adult obesity rate was 20% in 2003 compared with 23% nationwide in 2004.The national average has nearly doubled from 12% in 1993, the report said.

    Overweight and obese are defined by body mass index, or BMI (= kg/m) , which is based on a person’s weight , adjusted(調(diào)整) for height, the department said.

    Being obese means having a BMI of 30 or greater, while being overweight means a BMI of more than 25 but less than 30.

    A 5-foot, 10-inch (1.78-meter) man weighing 175 pounds(79kg) would have a BMI of 25.1 and be considered overweight according to the department . If he weighed 210 pounds (95kg), he would have a BMI of 30.1 and be obese.

    The report came from results of the department’s 2002 and 2003 yearly telephone surveys of some 10,000 adults.

1.New York City has a population of about _____ according to the passage.

  A.5,000,000  B. 2,000,000  C. 1,000,000 D. 500,000
