根据下面材料，回答题。

U. S. Life Expectancy Hits New High

Life expectancy rates in the United States are at an all-time high, with people born in 2005 projected to live for nearly 78 years, a new federal study finds.

The finding reflects a continuing trend of increasing life expectancy that began in 1955, when the average American lived to be 69.6 years old. By 1995, life expectancy was 75.8 years, and by2005, it had risen to 77.9 years, according to the report released Wednesday.

"This is good news." said report co-author Donna Hoyert, a health scientist at the National Center for Health Statistics. "It&39;s even better news that it is a continuation of trends, so it is a long period of continuing improvement."

Despite the upward trend, the United States still has a lower life expectancy than some 40 other countries, according to the U. S. Census (人口普查)Bureau. The country with the longest life expectancy is Andorra at 83.5 years, followed by Japan, Macau, San Marino and Singapore.

Much of the increase owes to declining death rates from the three leading causes of death in the country-heart disease, cancer and stroke.

In addition, in 2005, the U. S. death rate dropped to an all-time low of less than- 800 deaths per100,000.

Dr. David Katz, director of the Prevention Research Center at Yale University School of Medicine, said, "News that life expectancy is increasing is, of course, good. But the evidence we have suggests that there is more chronic disease than ever in the U. S."

Adding years to life is a good thing, Katz said. "But adding vital life to years is at least equally important. If we care about living well, and not just longer, we still have our work cutout for us." he said.

Since 1955， life expectancy rates in the U. S. have ___________. 查看材料

A.moved up and down

B.been declining

C.remained steady

D.been on the rise

阅读材料，回答题。

Many a young person tells me he wants to be a writer. I always encourage such people, but I also explain that there’s a big difference between "being a writer" and writing. In most cases these individuals are dreaming of wealth and fame, not the long hour alone at a typewriter. "You’ve got to want to write," I say to them, "not want to be a writer. "

The reality is that writing is a lonely, private and poor paying affair. For every writer kissed by fortune there are thousands more whose longing is never rewarded. When I left a 20 year career in the U. S. Coast Guard to become a freelance (自由栏目) writer, I had no prospects at all. What I did have was a friend who found me my room in a New York apartment building. It didn’t even matter that it was cold and had no bathroom. I immediately bought a used manual typewriter and felt like a genuine writer.

After a year or so, however, I still hadn’t gotten a break and began to doubt myself. It was so hard to sell a story that I barely made enough to eat. But I knew I wanted to write, I had dreamed about it for years. I wasn’t going to be one of those people who die wondering: What if？ I would keep putting my dream to the test even though it meant living with uncertainty and fear of failure. This is the shadow land of hope, and anyone with a dream must learn to live there.

The passage is meant to__________ 查看材料

A.warn young people of the hardships that a successful writer has to experience

B.advise young people to give up their idea of becoming a professional writer

C.show young people it’s unrealistic for a writer to pursue wealth and fame

D.encourage young people to pursue a writing career

请根据短文内容，回答题。 Traffic Jams——No End in Sight（1) Traffic congestion （拥堵) affects

请根据短文内容，回答题。

Traffic Jams——No End in Sight

(1) Traffic congestion (拥堵) affects people throughout the world. Traffic jams cause smog in dozens of cities across both the developed and developing world. In the U. S., commuters (通勤人员 ) spend an average of a full working week each year sitting in traffic jams, according to the Texas Transportation Institute. While alternative ways of getting around are available, most people still choose their cars because they are looking for convenience, comfort and privacy.＜br＞

(2) The most promising technique for reducing city traffic is called congestion pricing, whereby cities charge a toll to enter certain parts of town at certain times of day. In theory, if the toll is high enough, some drivers will cancel their trips or go by bus or train. And in practice it seems to work: Singapore, London and Stockholm have reduced traffic and pollution in city centres thanks to congestion pricing.＜br＞

(3) Another way to reduce rush-hour traffic is for employers to implement flextime, which lets employees travel to and from work at off-peak traffic times to avoid the rush hour. Those who have to travel during busy times can do their part by sharing cars. Employers can also allow more staff to telecommute (work from home) so as to keep more cars off the road altogether.＜br＞

(4) Some urban planners still believe that the best way to ease traffic congestion is to build more roads, especially roads that can take drivers around or over crowded city streets. But such techniques do not really keep cars off the road; they only accommodate more of them.＜br＞

(5) Other, more forward-thinking, planners know that more and more drivers and cars are taking to the roads every day, and they are unwilling to encourage more private automobiles when public transport is so much better both for people and the environment. For this reason, the American government has decided to spend some $7 billion on helping to increase capacity on public-transportsystemsandupgradethemwithmoreefficienttechnologies.But＜br＞

environmentalists complain that such funding is tiny compared with the $50 billion being spent on roads and bridges.
