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).
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.)
另外我自己的观点是所接宾语不同.
agree with sb
agree to do /sth
这是常用的
还有一个是agree on
agree on 一般接 point,price,date,address 等双方协定的内容.
