Our bodies are wonderfully skillful at keeping balance．When the temperature jumps, we sweat to cool down．When our blood pressure falls, our hearts can do something．As it turns out, though, our natural state is always changing．Researchers are finding that everything from blood pressure to brain function changes regularly with the cycles of sun, moon and seasons．And their insights （洞察力） are getting new ways for keeping away such common killers as heart disease and cancer．Only one doctor in 20 has a good knowledge of the scientific use of time in medicine．But according to a new American Medical Association, three out of four are eager to change that．“The field is exploding,” says Michael Smolensky．“Doctors used to look at us like, What spaceship did you get off ? Now they're thirsty to know more．”

In medical school, most doctors learn that people with chronic conditions should take their medicine regularly．“It’s a terrible way to treat disease,” says Dr Richard Martin．For example, asthmatics （气喘患者） are most likely to suffer during the night．Yet most patients try to keep a constant level of medicine in their blood day and night, whether by breathing in on an inhaler （吸入器） four times a day or taking a pill each morning and evening．In recent studies, researchers have found that a large mid afternoon dose of a bronchodilator （支气管扩张剂） can be as safe as several small doses, and better for preventing nighttime attacks．

If the night belongs to asthma, the dawn belongs to high blood pressure and heart disease．Heart attacks are twice as common at 9 a．m．as at 11 p．m．Part of the reason is that our blood pressure falls at night, then rises as we start to work for the day．“Doctors know that,” says Dr．Henry Black of Chicago's Medical Center, “but until now, we haven't been able to do anything about it．” Most blood - pressure drugs provide 18 to 20 hours of relief （减缓）．But because they’re taken in the morning, they're least effective when most needed．“You take your pill at 7 and it's working by 9,” says Dr．William White of the University of Connecticut Health Center “But by that time you've gone through the worst four hours of the day with no protection．” Bedtime medicine would prevent high blood pressure, but it would also push blood pressure to dangerously low levels during the night．

Researchers are finding that _________ ．

A．heart disease and cancer are the most common killers of human beings

B．only blood pressure and brain function are decided by cycles of sun, moon and seasons

C．the functions of human bodies have much to do with nature

D．any change in human bodies goes with changes in the surroundings

According to the author, it is best for asthmatics to take their medicine _________ ．

A．at certain time

B．each morning and evening

C．when the disease occurs

D．at midafternoon

Which of the following statements is NOT true?

A．Doctors know more about illnesses than before．

B．Doctors in the U．S．used to be thirsty to know more about the new medical field．

C．The researchers' insights are providing new methods to prevent common killers．

D．The correct use of time in medicine attracts more attention in medical circle in the U．S．A．

The suggested title for this passage might be _________．

A．Medicine Is Everything B．Treatment Is Everything

C．Timing Is Everything D．Prevention Is Everything

“The pen is more powerful than the sword(剑).” There have been many writers who used their pens to fight things that were wrong. Mrs Harriet Beecher Stowe was one of them. She was born in the U.S.A. in 1811.One of her books not only made her famous but has been described as one that excited the world, and was helpful in causing a civil war and freeing the enslaved race. The civil war was the American Civil War of 1861,in which the Northern States fought the Southern States and finally won.

This book that shook the world was called Uncle Tom’s Cabin. There was a time when every English-speaking man, woman, and child has read this novel that did so much to stop slavery. Not many people read it today, but it is still very interesting. The book has shown us how a warm-hearted writer can arouse(唤起) people’s sympathies. The author herself had neither been to the Southern States nor been a slave. The Southern Americans were very angry at the book, which they said did not at all represent true state of affairs, but the Northern Americans were wildly excited over it and were so inspired by it that they were ready to go to war to set the slaves free.

D．No war can be won without such a book as Uncle Tom's Cabin .

Why did the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road.
“Millions of animals die each year on U.S. roads,” the Federal Highway Administration reports. In fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
“Eco-passages” may help animals cross the road without being hit by cars. They are paths both over and under roads. “These eco-passages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the eco-passages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway. This showed that the lions used the passage.
Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders (火蜥蜴) and grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal overpass!
41. The writer uses the example of “ocelots” to show that _______.
A. wild animals have become more dangerous
B. the driving condition has improved greatly
C. the measure for protecting wildlife fails to work
D. an increasing number of animals are killed in road accidents
42. From the story, we know an eco-passage is ________.
A. an underground path for cars                  B. a fence built for the safety of the area
C. a bridge for animals to get over a river       D. a path for animals to cross the road
43. When the writer says that “animals seem to be catching on”(Para. 6), he means __.
A. animals begin to realize the dangers on the road
B. animals begin to learn to use eco-passages
C. animals are crossing the road in groups
D. animals are increasing in number
44. The writer asks visitors and drivers to look around when traveling because _____.
A. wild animals may attack cars                 B. wild animals may jam the road
C. they may see wild animals in the park D. they may see wild animals on eco-passages
45. The best title for the passage is ________.
A. Special bridges help animals cross the road      B. Endangered animals increase because of roadkill
C. Animals fail to cross the road                 D. Take steps to protect animals in danger

Is there a nationwide shortage of nurses? It’s hard to say．However, some characteristic symptoms often indicate that there is indeed a shortage．

One symptom is the vacancy rate, or the percentage of budgeted positions that are unfilled．New England’s hospitals currently report that an average of 7 to 12 percent of their registered nurse positions are vacant, the highest level since the last shortage in the late 1980s．Vermont has a relatively low vacancy rate, at 7．8 percent．But its vacancies were at 1．2 percent just five years ago．

Another symptom is the increased use of stopgap measures to fill empty positions．For instance, many nurses report an upswing in how frequently they are asked to stay past their shifts．According to Murphy, working in the St．Elizabeth’s Hospital, “The shortage has definitely created a lot of opportunities of overtime for our nurses, whether they want them or not．” Similarly, a national survey of registered nurses shows that in an average week, nurses in the U．S．work 2．4 more hours than they are scheduled to．Much of this extra time is voluntary, as nurses earn overtime pay when they stay to fill in blanks in the schedule．

When they can’t fill open positions by more traditional means, health care providers hire temporary staff to tide them over．Travelling workers are the largest part of the temporary health care workforce, hired for thirteen-week reduction at health care facilities facing short-term lack of workers．Temporary workers, mainly nurses, cost hospitals $ 7．2 billion in 2000．

“Any successful solution to the shortage depends on convincing more people to become nurses, and that is not an easy goal to reach．To achieve it,” says Buerhaus, “society needs to place more value on nursing．Legislation （法规） can’t do that – it should come from people．” And if this continues, we might have to learn to care for ourselves in the hospital．

1.The temporary staff hired by a hospital _______．

A．cost a large part of the hospital’s budget

B．meet the need for nurses in the hospital for a short time

C．should work on a weekly basis and on a scheduled timetable [来源:ZXXK]

D．ought to work passively for thirty continuous weeks

2.According to Buerhaus, what is a successful solution to the nurse shortage?

A．To convince people of the benefits of being a nurse．

B．To ask the government for help to work out specific legislation．

C．To publicize the past achievements of nurses．

D．To make people aware of the importance of being a nurse．

3.What’s the probable meaning of the underlined word “upswing” in Paragraph 3?

A．Symptom B．Decrease C．Increase D．Figure

4.What’s the author’s attitude towards nurse shortage?

A．Worried B．Indifferent C．Doubtful D．Optimistic
