Another thing that I found very difficult was English grammer

问题描述:

Another thing that I found very difficult was English grammer
这个句子如何分析?difficult是形容词,怎么能做found的宾语呢?

find sth (to be) difficult/easy/funny
to be 一般都省掉了,所以difficult不是宾语,而是to be 里面be的表语.
I found another thing (to be) difficult.It was English grammar.
