it very hard to还是it's very hard to?

还是都对？

如果不作主句,可以用it very hard to,如:
I found it very hard to understand.
作主句一定要用It's very hard to...

it's very hard to 是对的 相同的用法有： it's very difficult to do sth

it is hard for her to study hard to get good marks. 这个句子是将it 作为to get good marks 的形式主语。 后面的to表示目的。为了得到更高的分数

是 it's very hard to。。。 hard 是形容词，不能做谓语呀， 要靠is这个系动词啊~~~ 系表结构嘛~~~

it's very hard to do sth.正确 做……很难 it very hard to句子中缺少谓语动词

it's very hard to 对 hard是困难的意思 这是一个英语常见句型 It is +形容词（+for/of sb.)+to do sth. 中文意思是 对于某人来说做某事怎么样 其中It是形式主语 不定式才是真正主语
