He felt frustrated when he found （） impossible to catch up with heis classmatens
classmates
A it
B it is
我感觉都可以啊?
B为何不可？
1.答案：A.
2.翻译：当他发现不可能赶上他的同班同学们时,他感到很沮丧.
3.
1）答案A为典型的“及物动词find + 形式宾语it + 宾语补足语impossible + 真正宾语to catch...”结构.
有上述结构的动词一般有如下五个：find/make/feel/think/consider.
此结构的宾语补足语一般用形容词/名词充当,而真正的宾语一般由不定式（复合结构）或that从句充当.
2）上述结构经常可以转化成：find/feel/think/consider（make不可以）+ that从句.
而且该that从句结构为：it be + 形容词/名词（即上述结构的宾语补足语） + （for sb）+ to do sth/that从句.
如：I found it easy to learn English.
= I found (that) it was easy to learn English.
3）该题答案B之所以错误,原因很简单,就是这个从句的时态必须和主句时态found一致(都采用一般过去时),即be动词是was,而不是is.
A
find it + adj.固定用法
it is possible to do sth一般都这么用
found it impossible to catch up with his classmates
or
found that it is impossible (for him) to catch up with his classmates
A
固定用法 find it +形容词
这道题是考查it 作为形式宾语的。
1.宾语是不定词或名词字句时，须用形式宾语(it)，写成V+it+形容词+ 不定词或名词子句.比如说:
He made it clear what he intended to do.
I take it for granted that you will give me a hand.
They feel it neces...

这道题是考查it 作为形式宾语的。
1.宾语是不定词或名词字句时，须用形式宾语(it)，写成V+it+形容词+ 不定词或名词子句.比如说:
He made it clear what he intended to do.
I take it for granted that you will give me a hand.
They feel it necessary to work harder.
在以上句子中,真正的宾语都不是it,而是句子的后半部分.
2.你所提到的问题是关于 find it +adj 这一习惯用法问题，由于习惯用法，比你想说：
I think it is difficult for me to explain this to you.
就可以直接说成
I think it difficult for me to explain this to you.
