Ants as a Barometer of Ecological Change
At picnics, ants are pests.But they have their uses.In industries such as mining,farming and forestry, they help gauge(测定)the health of the environment by just crawling around and being antsy(坐立不安).
It has been recognized for decades that ant.s-which are highly sensitive to ecological change-can provide a near-perfect barometer(气压计)of the state of an ecosystem.Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees.__ (1) And still others will move in and take up residence.
By looking at which species populate a deforested area, scientists can determine how "stressed"the land is.__ (2) Ants are used simply because they are so common and comprise(构成) so many species.
Where mine sites are being restored, for example, some ant species will recolonize(重新移民到…)the stripped land more quickly than others.__ (3) Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.
Ant surveys also have been used with mine-site recovery projects in Africa and Brazil,where warm climates encourage dense and diverse ant populations."We found it worked extremely well there,"says Jonathan Major, a professor of environmental biology.Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region.As Major puts it: "That's the great thing about ants "Ant surveys are so highly regarded as ecological indicators(指示器)that governments worldwide accept their results when assessing(评估) the environmental impact of mining and tree harvesting.__ (4)
Why not? Because many companies can't afford the expense or the laboratory time needed to sift(详审)results for a comprehensive survey.The cost stems, also, from the scarcity(缺乏)of ant specialists.__ (5)
A.This allowed scientists to gauge the pace and progress of the ecological recovery.
B.Yet in other businesses, such as farming and property development, ant surveys aren't used widely.
C.Employing those people is expensive.
D.They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.
E.The evolution of ant species may have a strong impact on our ecosystem.
F.Others will die out for lack of food.

Sleep Deficit(不足)
Judging from recent surveys, most experts in sleep behavior. agree that is virtually an epidemic of sleepiness in the nation. "I can't think of a single study that hasn't found Americans getting less sleep than they ought to. " says Dr. David. Even people who think they are sleeping enough would probably be better off with more rest.
The beginning of our sleep-deficit crisis can be traced to the invention of the light bulb a century ago. From diary entries and other personal accounts from the 18th 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9. 5 hours a night. "The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark. " By the 1950s and 1960s, that sleep schedule had been reduced dramatically, to between 7. 5 and 8 hours, and most people had to wake to an alarm clock. "People cheat on their sleep, and they don't even realize they're doing it, " says Dr. David. "They think they're okay because they can get by on 6. 5 hours, when they really need 7. 5, 8 or even more to feel ideally vigorous. "
"Perhaps the most merciless robber of sleep, " researchers say, "is the complexity of the day. " Whenever pressures from work, family, friends and community mount, many people consider sleep the least expensive item on his program. "In our society, you're considered dynamic if you say you only need 5. 5 hours' sleep. If you've got to get 8. 5 hours, people think you lack drive and ambition. "
To determine the consequences of sleep deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or re call a page read to them only minutes earlier. "We've found that if you're in sleep deficit, performance suffers, " says Dr. David. "Shot-term memory is weakened, as are abilities to make decision and to concentrate.
People in the 18th and 19th centuries used to sleep about 5 hours a night because they had ______.
A.no drive and ambition
B.no electric lighting
C.the best sleep habits
D.a lot to of the next day

A new study suggests that contrary to most surveys, people are actually more stressed at home than at work. Researchers measured people’s cortisol, which is a stress marker, while they were at work and while they were at home and found it higher at what is supposed to be a place of refuge.
“Further contradicting conventional wisdom, we found that women as well as men have lower levels of stress at work than at home, ” writes one of the researchers, Sarah Damske. In fact women even say they feel better at work, she notes.“ It is men, not women, who report being happier at home than at work. ”Another surprise is that findings hold true for both those with children and without, but more so for nonparents. This is why people who work outside the home have better health.
What the study doesn’t measure is whether people are still doing work when they’re at home, whether it is household work or work brought home from the office. For many men, the end of the workday is a time to kick back. For women who stay home, they never get to leave the office. And for women who work outside the home, they often are playing catch-up-with-household tasks. With the blurring of roles, and the fact that the home front lags well behind the workplace a making adjustments for working women, it’s not surprising that women are more stressed at home.
But it’s not just a gender thing. At work, people pretty much know what they’re supposed to be doing: working, marking money, doing the tasks they have to do in order to draw an income. The bargain is very pure: Employee puts in hours of physical or mental labor and employee draws out life-sustaining moola.
On the home front, however, people have no such clarity. Rare is the household in which the division of labor is so clinically and methodically laid out. There are a lot of tasks to be done, there are inadequate rewards for most of them. Your home colleagues-your family-have no clear rewards for their labor; they need to be talked into it, or if they’re teenagers, threatened with complete removal of all electronic devices. Plus, they’re your family. You cannot fire your family. You never really get to go home from home.
So it’s not surprising that people are more stressed at home. Not only are the tasks apparently infinite, the co-workers are much harder to motivate.
21.According to Paragraph 1,most previous surveys found that home_____
[A] offered greater relaxation than the workplace
[B] was an ideal place for stress measurement
[C] generated more stress than the workplace
[D] was an unrealistic place for relaxation
22. According to Damaske, who are likely to be the happiest at home?
[A] Childless wives
[B] Working mothers
[C] Childless husbands
[D] Working fathers
23.The blurring of working women's roles refers to the fact that_____
[A] it is difficult for them to leave their office
[B] their home is also a place for kicking back
[C] there is often much housework left behind
[D] they are both bread winners and housewives
24.The word“moola”(Line4,Para4)most probably means_____
[A] skills
[B] energy
[C] earnings
[D] nutrition
25.The home front differs from the workplace in that_____
[A] division of labor at home is seldom clear-cut
[B] home is hardly a cozier working environment
[C] household tasks are generally more motivating
[D] family labor is often adequately rewarded
