----Little Daniel is watering the flowers! Why?

-----Well, I’m not feeling very well today—otherwise I           it myself.

A．did              B．would do          C．have done         D．will have done

 

【答案】

B

【解析】

試題分析：考查虛擬語氣。本題是與現(xiàn)在事實相反的虛擬語氣，主句中使用“情態(tài)動詞+動詞原形”；本句的條件是通過副詞otherwise必須出來的。句意：—小Daniel正在澆花！為什么？—我今天身體不好。要不然，我會自己做的。根據(jù)句意說明是與現(xiàn)在事實相反，故B正確。

考點：考查虛擬語氣

點評：要注意條件句以及含蓄條件句的虛擬語氣的使用，如果過去事實相反，條件句中使用過去完成時，主句使用“情態(tài)動詞+have done”;

如果主句與現(xiàn)在事實相反，條件句中使用過去時，be動詞使用were,主句中使用“情態(tài)動詞+動詞原形”；如果與將來事實相反，條件句中有三種：過去時；were to do ;should+動詞原形，主句使用“情態(tài)動詞+動詞原形”；要特別注意如果省略了if，句子要使用部分倒裝的形式，把助動詞，be動詞，情態(tài)動詞提之主語前。

Here's a new warning from health experts: Sitting is deadly. Scientists are increasingly warning that sitting for prolonged periods — even if you also exercise regularly — could be   1  for your health. And it doesn't matter where the sitting takes place — at the office, at school, in the car or before a computer or TV — just the overall number of hours it   2   .

Research is preliminary, but several studies   3  people who spend most of their days sitting are more likely to be fat, have a heart attack or even die.

In an editorial   4  this week in the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define   5  activity to highlight the dangers of sitting.

While health officials have issued guidelines   6  minimum amounts of physical activity, they haven't suggested people try to limit how much time they spend in a seated   7  .

"After four hours of sitting, the body starts to send   8  signals," Ekblom-Bak said. She explained that genes regulating the amount of glucoseand fat in the   9  start to shut down.

Even for people who   10   , spending long stretches of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day —   11  still spend a lot of time sitting — might get more benefit if that exercise were spread across the day,    12  in a single bout.

That wasn't   13  news for Aytekin Can, 31, who works at a London financial company, and spends most of his days sitting    14   a computer. Several evenings a week, Can also teaches jiu jitsu, a Japanese martial art  15  wrestling, and also does Thai boxing.

"I'm sure there are some detrimental   16  of staying still for too long, but I hope that being   17  when I can helps," he said. "I wouldn't want to think the sitting could be   18  dangerous."

Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat   19  had a higher death risk, independently of whether or not they exercised.

Figures from a US survey in 2003-2004 found Americans spend more than half their time sitting, from working at their desks to sitting in cars.

Experts said more research is needed to    20  just how much sitting is dangerous, and what might be possible to offset those effects.

Last year, Jack Bleed cut through the bone of his ring finger while working. The 31-year-old resident of North Little Rock, Arkansas, waited for about six hours at a nearby medical center while the medical staff there called all over town — even as far away as Dallas and Memphis — to find a hand surgeon to reattach his finger. Finally, a willing doctor was located in Louisville, Kentucky. But even though Bleed had insurance(保險), he would have to hire a private plane to get himself there, at a cost of $4,300. In the end, he charged the cost to two credit cards, and his finger was saved. His insurance company eventually covered the cost of the plane, but his experience makes people aware of the fact that trauma(外傷) care in the United States is not only geographically limited, but in many places, non-existent.

Only eight states — New York, New Jersey, Maryland, Illinois, New Mexico, California, Oregon, and Washington — have local, fully functional trauma systems. The remaining states have partial systems, and 12 — including Arkansas — have no trauma system at all.

Although the President has signed a bill of $12 million for the purpose of supporting trauma care systems nationwide, many in Congress(國會) are unwilling to spend government money for a service they think should be paid for by states, says Wayne Meredith, medical director for trauma programs at the American College of Surgeons. Meanwhile, many states have also failed to find the dollars to support trauma systems. To make matters worse, many people without insurance depend heavily on the emergency care services, placing a huge financial burden on the medical centers that serve them.

For the same reason, doctors, too, often go unpaid. They are unwilling to perform emergency care, worsening critical shortages of neurosurgeons, orthopedists, and hand surgeons — the very types of specialists Bleed needed at short notice.

Supporting a trauma care system doesn’t take much. A half-penny sales tax in Miami-Dade County makes its outstanding system work. In Arkansas alone, says Wayne Meredith, a well-funded trauma system would possibly prevent 200 to 600 deaths each year. If trauma care systems were to work well across the nation, experts say, many thousands of lives each year could be saved. “You don’t get much better return on your investment than that,” Meredith says.

In Paragraph 1, the writer uses Bleed’s case to ______.

A. make a comparison                               B. describe a person

C. introduce a topic                                          D. tell a story

Many people in Congress argue that trauma care systems should be supported by ______.

A. the President                                       B. each state

C. insurance companies                              D. the US government

The example of Miami-Dade County shows that ______.

A. its tax policy is admirable                      B. running a trauma system is profitable

C. a trauma system is not expensive            D. sales tax is not heavy in small counties

Why are the present trauma care systems in some states not satisfactory?

A. They are shared by all the states.                    B. They are short of financial support.

C. The doctors are not well trained.                    D. The hospitals can’t provide low-cost services.

Seasonal influenza is characterized by a sudden fever, cough, headache, muscle and joint pain, sore throat and runny nose.

Influenza epidemics occur    12   during autumn and winter in temperate regions. Illnesses result in hospitalizations and deaths mainly among high-risk groups. Worldwide, these annual epidemics result in about three to five million   13     of severe illness, and about 250 000 to 500 000 deaths.

Influenza can cause serious public health and economic problems. In   14    countries, epidemics can result in high levels of worker absenteeism and productivity   15   .   16    most people recover from a bout(輪) of influenza, there are large numbers of people who need hospital treatment and many   17    die from the disease every year.   18     is known about the effects of influenza epidemics in developing countries.
