怎么分析句子成分啊
答
这是一个固定用法，XX find it adj.> to do XX
如果一定要分析句子成分的话
He是主语 found是 谓语
it 是形式宾语 very difficult是宾语补足语
to learn maths 是动词不定式作真正的宾语
答
He主语 found 谓语it 形式宾语very difficult宾语补足语 to learn maths 动词不定式作真正的宾语
答
你那句有错
宾语从句
he found (that) it is very difficult to learn maths
it是形式主语,带的to learn maths,主语太长,所以要指代
to learn maths is very difficult
