I find it difficult to learn English 中it 作形式宾语,真正的宾语的后面的不定式
I find that it is difficult to learn English 中it 作that 引导的宾语从句中的形式主语,真正的主语是后面的不定式
I found the football match was really wonderful是found后面引导的一个宾语从句,而I found the football match really wonderful 此时wonderful是作来修饰宾语football match的,是作它的补足语,两句话都是对的,第二句话更高级些,
