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.

答案是D，但我选了A

我想问的是选项D中highlight部分是什么意思？  谢谢~~

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.

答案是A，但我不理解，这个argument和选项中的男女是不是因为类比？？

D 选项说的是大部分的学校布置的作业和平均值相差不大 黄色部分的字面意思是 没有极大地偏离平均值 意思明白了 D也就很显然是答案了 典型的取非削弱

第二题我也不是很理解 后面几个转折很奇怪 我都转晕了 一起等高手解答

谢谢你的解答~~

一起等待NN~~
