1、a/b/c第一步扔掉，比较d/e.d用的是动词increase，所以选D.

2、a/d第一步扔掉，比较b/c/e，e是比较容易从平行结构排除的；比较b/c，优先使用动词所以C

3、prohibit ... from ......比较c/d,d是明显不好！

4、第一步扔掉bce,比较a/d，a的后半部分更加简洁。

5、如果你熟悉时态，你马上可以选A.
可以用另外的解法：扔掉B,比较a/c，都用to do结构，但是c中的were是不对的；比较de,你肯定会留下d.比较a/d,d的错误和c是一样的。

我先给你解答5个题目，你的帖子太长了。把我的眼睛都看花了！请下次贴题目的时候不要每贴超过3个，方便大家回答。

剩余部分：
30、be responsible for doing

31、时态的合理使用：nearly a century of case-by-case 用现在完成时

32、请你看看动作ascend的发出是主动还是被动！‘

再给你提一个建议：你的这8个题目都比较简单，有些错题你应该自己多分析才能提高！
