Question

Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.
Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress(紧张) levels and blood pressure in people—half of them pet owners—while they performed 5 minutes of mental arithmetic(心算) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quick to base line heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed around pets, says Allen, who thinks it may be because pets don't judge
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about 11 pounds, or 5% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall—mostly with their dogs—and found it worth doing.

点评：主旨大意题要识别和理解主题句，可迅速准确地抓住短文的中心思想，从而把握住全篇的主要内容。在确定文章的主旨思想时，选项的内容既不能太具体也不能太笼统。在选择和确定主旨思想时，题中给出的四个选择项往往都是事实，要求考生从中选出最能概括文章主旨思想的一项作为正确答案。在这方面考生容易犯以下两种错误：一种是把主题的一部分看成是文章的“主旨思想”，这样选择的“主旨思想”太具体，不能准确地概括出整个文章或段落的主旨思想。另一种是在表达作者的主旨思想时，词语概括的范围太大，太笼统，超出了作者的本意。
