It's+adj+to do sth/for sb. to do sth /that+从句的例题

It is important to do these things.It`s important for them to do these things.It`s ijmportant that tey do these things.

意思本来就一样的，只是用法上的区别
如It is important to learn English
It is important that we learn English
关键就是一个接动词词组，一个接从句（主语从句）

It's good to keep healthy.It's hard for him to do the work.It's wonderful that we won!
