of animals that are kept in zoos.

D. There is no occupation for which the risk of developing an animal-induced allergy is higher than 30 percent. E. Among members of the general population who have spent as much time with animals as zoo employees typically

have, the percentage with animal-induced allergies is significantly more than 30 percent. ------------------------------------------------------------------------------------------------------- 29. GWD26-Q29 Educational Theorist:

Recent editorials have called for limits on the amount of homework assigned to children. They point out that free-time

activities play an important role in childhood development and that large amounts of homework reduce children‘s free time, hindering their development. But the average homework time for a ten year old, for example, is little more than 30 minutes per night. Clearly, therefore, there is no need to impose the limits these editorials are calling for. Which of the following is an assumption on which the educational theorist‘s argument relies?

A. The free-time activities that ten year olds engage in most are all approximately equally effective at fostering

development B. Regularly doing homework assignments improves children‘s academic performance.

C. Individual teachers are not the best judges of how much homework to assign the children they teach

D. In most schools, if not all, the homework assignments given are of a length that does not diverge widely from the

average. E. Free-time activities rarely teach children skills or information that they can use in their academic work.

My opinion: 从此题好象可以看出，对于法规/limit/,用average来argue是不行的，因为限制并不是对average起作用的，而是对最低或者最高起作用的。？？

31. GWD26-Q31 此题要小心，不能一下子排除A,有时候靠感觉是不对的，而且关键要有理才行。 Which of the following most logically completes the argument?

When people engage in activities that help others, their brain releases endorphins, the brain‘s natural opiates, which induce in people a feeling of well-being. It has been suggested that regular release of endorphins increases people‘s longevity. And a statistic on adults who regularly engage in volunteer work helping others shows that they live longer, on average, than adults who do not volunteer. However, that statistic would be what we would expect even if volunteering does not boost longevity, because .

A. in the communities studied, women were much more likely to do regular volunteer work than men were, and women

tend to live longer than men do. B. the number of young adults who do regular volunteer work is on the increase

C. the feelings of well-being induced by endorphins can, at least for a time, mask the symptoms of various conditions and

diseases, provided the symptoms are mild. D. it is rare for a person to keep up a regular schedule of volunteer work throughout his or her life.

E. Some people find that keeping a commitment to do regular volunteer work becomes a source of stress in their lives.

支持A

理解原文最后一句话最关键:即使volunteering不能增加人的寿命,那组统计数据也一样,没有变化,都是volunterring比没有voluntering的人长寿.说明这组人比较特殊.这些人寿命本来就长,不作voluntering寿命也长. A的意思是那组数据统计的是妇女,而他们通常比较长寿.所以拿这些人去统计,结果会是比平均成年人长命,即使扣除他们做的volunteering使他们长寿的因素. lawyer
