It is diffcult for him to do it 谓语是is diffcult吗 那for只是介词吗
It is diffcult for him to do it 谓语是is diffcult吗 那for只是介词吗
It is diffcult for him to do it 谓语是is diffcult吗 那for只是介词吗
It is diffcult for him to do it.
此句完全正确,你说得也非常对!谓语是is diffcult,是系表结构做谓语;for是介词;
is 是谓语
谓语?应该是do it的do
for应该是介词
形式主语it
真正主语to do it
系动词is
表语difficult
状语for him
谓语动词是系动词is for在这里是介词
It 是形式主语
It(形式主语) is (谓语) diffcult(表语,宾语) for him to do it (真正的主语)。
本句子是遵循了英语中的常用处理方法,避免头重脚轻。it 做形式主语,to do it 做真正的主语,谓语是is
如果要还原句子本来面目应该是to do it for him is diffcult,这样本来是没问题的,但是这样的话句子主语太长,谓语太短,所以就成加来it来改善
很多时候句子都是这种,它可以记忆为: it is +形容词+for sb to do sth...
