agree on 和agree to的不同

agree on sth 表某种观点
agree to do sth 表做某事

agree with, agree to,意思是一样的，可是用法不同，他们都是同意某件事或某个人的意见的意思。
1 agree with,的用法是这样的：agree with+doing something或者+somebody
例句：I ageree with going to swim tomorrow.(我同意明天去游泳.)
I agree with you.(我同意你的意见)
2 agree to的用法是这样的：agree to +do something 决不可以agree to somebody.因为agree to 中to后面加动词不定式.指明是动词.
例句:I agree to go to swim tomorrow..(我同意明天去游泳.)
agree to do sth.
表示答应做某事
eg. They agreed to go with us.
决不能说 agree sb. to do sth.
agree on sth.
主语一般是复数形式的名词，表示一致同意。
eg. Both of us agreed on the contact.

简便记
agree on 双方就某一问题达成一致
agree to + 计划或建议

agree on sth 而agree to sb 也就是后面接的对象不一样，一个是人，一个是事情！

agree to sth．表示“同意计划、建议、决定”等，后面常接指物的名词或代词。

如：I agree to your idea． 我同意你的想法。

另外，该短语中的to有时也可作为动词不定式的符号，后接动词原形。

如：They agree to do it now． 他们同意现在做这件事。
I agree to help him with his lessons． 我答应帮他复习功课。

agree on／upon sth．表示“就某事达成一致意见或协议”，强调双方相互同意所说的内容。

如：We agree on／upon it．
