很郁闷,希望有同志们点拨我的ASSUMPTION

开始做LXD的逻辑,assumption真是做几道就要错几道，想死的心都有了。。。。

然后上CD看了看LAWYER的讲解，可能水平有限。。完全吃不透。。。

就LAWYER所说的充分和必要题型，在具体的题目中该怎么区分呢？

附加求助一题

The sense of delayed gratification, of working now for later pleasure, has helped shape the economic behavior of our society. However, that sense is no longer nurtured as consistently in our childern as it once was. For example, it used to take a bit of patience to put together the toys that childern got in cereal boxes; now the toys come from the boxes whole.

Which of the following is an assumption of the passage above?

A.  The toys in cereal boxes have changed partly because the economic condition of our society have improved.
B.  The influence of promotion gimmicks on the economic behavior of our society has increased over the years.
C.  The toys that used to come in cereal boxes were put together by the same children who play with them.
D.  art of the pleasure of any toy lies in putting the toy together before playing with it.
E.  Today's children do not ecpect a single toy to provide pleasure for a long period of time.
答案是C  可是我完全不理解。。。

个人认为选项C,可以通过排除他因法。

题目说到：迟来的满意，或者为了将来的幸福而现在工作，这些行为塑造了我们这个社会的经济行为。但是，现在的小孩子不是这样了。并且举了个例子，过去，为了将玩具组装到一起，需要一些耐心才能可以；而现在，这些玩具是完整的一个就来了。

选项C排除了削弱该结论成立的可能性，如果在过去，这些玩具并不是由同一个小孩放在一起的，那么说过去的小孩子锻炼了耐心就不成立，从而结论也就不成立了。而选项C，排除了这种可能性，从而作为题目的一个assumption.

个人看法，继续讨论。
