be committed to doing sth和commit to doing sth 有什么区别?

没有区别.
例如:
I am committed to
improving the health of
women everywhere.
I commit to create a
culture of
innovation.
都是 承诺做某事 的意思那例如:committed to sponsoring those poor students at university,you must live up to your promise。为什么就不能用committing??那你直接上这句话不就得了。你给的例句,其实完整的应该是:You are committed to sponsoring those poor students at university. You must live up to your promise.把两个句子变成一个句子,后面的是主句,前面的是从句表原因。然后这里的committed to 其实是be committed to 的省略形式, Committed to 引导了一个原因状语从句。至于这个缩写,原因是:如果主句主语和从句主语相同,并且从句中有be动次,可以省略从句的主语和be动词,直接用分词表示。在你的例句中,主句的主语和从句的主语是一致的(都是You),并且从句是be done的形式(you are committed to.....),所以从句的 主语和be动词要省略掉,然后就变成了你的例句:(You are) Committed to sponsoring those poor students at university, you must live up to your promise.
