Answer 1

1.While doing my homework,
这半句话是非谓语动词作状语,你看它是没有主语的.这种情况下只可能是依据主句（暂且这么称）的主语省略.而此剧中的逻辑主语很明显是“我”,选项中只有A是I 作主语.选择其他选项句子逻辑上,语法上都不对.
2.
3.此题考查主语从句.
如果选择C,那句子还原就是
The fact he said at the meeting astonished everyboby present.
此句中The fact he said at the meeting 是主句的主语,因为是一个句子作主语所以是主语从句.但主语从句与主句之间必须有连接词.因此 The fact he said at the meeting 不能单独做从句.The fact 不成立.而What he said 中What 既做了said 的宾语又连接了从句和主句,成立.
