求解一道英语题

I found ________meaningfui to rebuild houses for people in Wenchuan
A.that B.it C.this D.them

Answer 1

答案：B

解释：found是感官动词find的过去式，而it是形式宾语，后面的不定式短语to rebuild houses for people in Wenchuan是感官动词found的真正宾语，而形容词meaningful做宾语补足语。
三种构成所谓的“感官动词 + 宾语 + 宾语补足语”结构。
在英语中，只有it才可以充当句子的形式主语/宾语，其他选项不可以。
此句也可以转换成一下结构进行理解，即：
I found (that) it was meaningful to rebuild houses for people in Wenchuan.
此时it做found的宾语从句中的形式主语，而不定式短语 to rebuild houses for people in Wenchuan做宾语从句中真正的主语。

Answer 2

选择B

Answer 3

选B，it是形式宾语，代替后面的不定式to rebuild houses for people in Wenchuan
