At picnics, ants are pests. But they have their uses. In industries such as mining, farming and forestry ,they can help gauge (测量) the health of the environment by just crawling around and being antsy.
It has been recognized for decades that ants—which are highly sensitive to ecological change—can provide a near-perfect barometer of the state of all ecosystem. Only certain species, for instance, will continue to thrive (兴旺, 欣欣向荣)at a forest site that has been cleared of trees. Others will die out for lack of food. 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. They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys. Ants are used simply because they are so common and comprise so many species.
Where mine sites are being restored, for example, some ant species will recolonize the stripped land more quickly than others. This allowed scientists to gauge the pace and progress of the ecological recovery. 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 Majer, 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 Majer puts it. "That’s the great thing about ants. "
Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. Yet in other businesses, such as farming and property development, ant surveys aren’t used widely. Why not Because many companies can’t afford the expense or the laboratory time needed to sift(细查, 祥查) results for a comprehensive survey. The cost stems, also, from the scarcity of ant species.
Scientists can determine how seriously an area has been affected by deforestation by

A:examining which species populate this area. B:counting the numbers of ants living in this area. C:looking at what kinds of ants are living in the area. D:by analyzing data from earlier surveys.

Karen Rusa was a 30-year-old woman and the mother of four children. For the past several months Karen had been experiencing repetitive thoughts that centered around her children’s safety. She frequently found herself imagining that a serious accident had occurred; she was unable to put these thoughts out of her mind. On one such occasion she imagined that her son, Alan, had broken his leg playing football at school. There was no reason to believe that an accident had occurred, but she kept thinking about the possibility until she finally called the school to see if Alan was all right. Even after receiving their assurance that he had not been hurt, she described herself as being some- what surprised when he later arrived home unharmed. Karen also noted that her daily routine was seriously hampered by an extensive series of counting work that she performed throughout each day. Specific numbers come to have a special meaning to her; she found that her preoccupation with these numbers was interfering with her ability to perform everyday activities. One example was grocery shopping. Karen believed that if she selected the first item, some dreadful thing would happen to her first child, if she selected the second item, some unknown disaster wonld fall on her seconol child, and so on for the four children. Karen’s preoccupation with numbers extended to other activities, most notable the pattern in which she smoked cigarettes and drank coffee. If she had one cigarette, she believed that she had to smoke at least four in a row or one of her children would be harmed in some way. If she drank one cup of coffee, she felt compelled to drink four. Karen acknowledged the unreasonableness of these rules, but, nevertheless, maintained that she felt more comfortable, when she observed them earnestly. When she was occasionally in too great a hurry to observe these rules, she experienced considerable anxiety in the form of a subjective feeling of dread and fear. She de- scribed herself as tense, uneasy and unable to relax during these periods.
Which of the following solutions could most probably cure Karen of the illness

A:Her children were all right. B:She stopped counting numbers. C:She consulted a psychoanalyst. D:She quit smokin
