agree to和 agree with的区别?

agree with sb.
agree to sth.
这样接比较多一点。意思没有太大的差别的。

Agree的用法
agree后面接介词法比较复杂，常见用法有：
(1) 涉及讨论的题目用about。
They never agree about politics. 关于政治问题，他们总是意见不一致。
(2)要确定一样事情用on。
Can we agree on a date for the next meeting? 我们能不能为下次会议确定一个时间？
(3)涉及一件建议或计划用to。
He’s agreed to our suggestion about the holiday. 他已经同意我们关于假日的计划了。
(4)涉及意思、想法、分析、解释以及涉及人的时候用with。
They might not agree with his opinions. 他们可能不同意他的意见。
(5)agree后可接动词不定式或宾语从句。
We agree to leave at once. 我们同意马上离开。
agree一般常用口语用法
(1)I can't argue with you about that.
我无法与您争辩那件事。
(2)You can say that again.
您说的对极了。
(3)You took the words right out of my mouth.
您已说出我心里的话。
(4)I was about to say the same thing.
我正想提出同样看法。
(5)I couldn't agree with you more.
我极表同意您的看法。
注意
上列类似用语"I couldn't agree with you more."，按字面翻译为「我无法再更加同意您了」，实则表「我对您极表同意」。注意这是固定句型，助动词必须用couldn't，而不可用can't。

agree with 和agree to 的区别并不在于他们所接的宾语不同（一般认为agree with sb./agree with sth.),而在于他们具有不同的语意．
agree with 是指出自主观愿望的”赞成,同意”（have the same opinion) eg.
She agreed with the idea.
I agree with his view.
agree to 是指”接受,认可”,常常指并非出自主观愿望的”同意”．指不乐意或争论之后的同意．（to accept an idea,oppion,etc.,especially after unwillingness or arguement).
你可能agree to 一个政策,然而并不一定agree with 它

agree to do sth.同意做某事或者agree to sth.同意某事 agree with sb. 同意某人 但是也可以agree with sth.意思是与什么相符合,相吻合
