求教Zeldaw!

今天中午抽空做了一个section的大全，对目前做题错误分析如下，希望能得到nn指点：

关键第4点，现在想不出办法来解决，现把题目贴在下面：

10.   As part of their therapy, young polio victims learning to live with their disabilities were helped to practice falling during the 1950s, so that they could learn to fall without being hurt.

(A) As part of their therapy, young polio victims learning to live with their disabilities were helped to practice falling during the 1950s

(B) As part of their therapy, young polio victims learning to live during the 1950s with their disabilities were helped to practice falling

(C) Young polio victims learning to live during the 1950s with their disabilities were helped to practice falling as part of their therapy

(D) Young polio victims learning to live with their disabilities were helped to practice falling during the 1950s as part of their therapy（E）

(E) During the 1950s, as part of their therapy, young polio victims learning to live with their disabilities were helped to practice falling

问题是我做这道题时觉得第一眼找不到突破口，看了几遍还是犹豫，请教您遇到这样情况是怎么办的呢？能示范一下思路么？

周末做了下阶段的计划，希望nn指教：

......修饰关系，这个最难了.....

我最近都在忙申请，好久没看语法了。所以....至少这题在解题步骤上说不出什么....

所以引用阿诺的话：

这个解释未必通用。不过说得意思就是修饰对象要避免歧义。

这类题目现在考的好像考的比以前多了，PREP中有不少。 要注意一下

不会像这题一样只考这个，不过经常会作为混淆选项，很讨厌。

恩，这题我看过讨论，上面的解释也理解了，只是想说，这样的题目在考试的时候遇到挺耗时的，题目第一遍难读懂又没有明显错误...看来我是不熟悉这样的题，我需要多做做PREP了

申请耗心耗力强度不低于考试，Zeldaw NN加油！
