Question

I find ___ him all about it. A necessary B that nessary C necessary it to tell

D it necessary to tell
选哪个啊？

Answer 1

解答：I find （填D， it necessary to tell） him all about it.
句意：我觉得有必要把所有的情况都告诉他。
理由：find it + 形容词 + to do，认为、觉得、发现做某事怎么样。

Answer 2

D原句可改写成： I find to tell him all about it necessary
it =to tell him all about it 为形式宾语
necessary 是选项前面这个it 的补语

Answer 3

D
