一，agree的正确用法
◆他们同意我做这事。
误：They agreed me to do it.
正：They agreed to let me do it.
正：They agreed to my doing it.
析：不要按汉语习惯用 agree sb to do sth 来表示“同意某人做 某事”, 要表示此意, 需改用其它结构。
◆他们大多数同意帮助我们。
误：Most of them agreed helping us.
正：Most of them agreed to help us.
析：表示同意做某事，agree 后要接不定式，不接动名词。
◆他想出国，但我们没一个人同意。
误：He wanted to go abroad, but none of us agreed (to) him.
正：He wanted to go abroad, but none of us agreed with him.
析：表示同意某人(或某人的想法、意见等), 要用 agree with sb, 不用 agree (to) sb。
◆这种天气对她不适宜。
误：The weather does not agree to her.
正：The weather does not agree with her.
析：表示“(食物、天气、工作等)对 ...适宜”, 英语要用 agree with。如：
Hard work does not agree with him. (艰苦的工作对他不适宜)。/ Such food doesn’t agree with babies. (那样的食物对婴儿不适合)
◆我们已商定好了这辆旧车的价钱。
误：We have agreed with (to) the price for the old car.
正：We have agreed on the price for the old car.
析：agree on 指双方通过讨论或协商而取得一致的意见或达成协议，其主语通常为复数形式或表示复数意义的词。又如：We didn’t agree on when to start.
(关于什么时候出发, 我们没有达成一致意见)。
二，agree短语
1. agree with
(1) 表示同意某人或某人的意见、想法、分析、解释等 (即持同一观点)。如：
I quite agree with you. 我完全同意你的意见。
We agree with what you say. 我们同意你说的。
(2) 表示“(食物、天气、工作等)对……适宜”。如：
The food does not agree with me. 这食物对我不适合。
Hard work does not agree with him. 艰苦的工作对他不适宜。
(3) 表示“与……一致”。如：
His story agrees with the facts. 他的陈述与事实相符。
A verb must agree with its subject in person and number.
动词必须和它的主语在人称和数方面保持一致。
2. agree to
(1) 后接某些名词，表示同意或接受某事，尤其指别人提出的某事，有时可能是自己不喜欢的事。
He agree the plan (the date). 他同意了这个计划(日期)。
We agreed to their arrangement. 我们同意了他们的安排。
I was forced to agree to it, but at heart I didn’t quite agree with it.
我被迫答应，但内心并不完全同意。
(2) 后接动词原形(此时to是不定式符号)或动名词(一般有逻辑主语，此时 to 是介词)。如：
We agreed to leave early. 我们同意早点出发。
She agreed to my going home. 她同意我回去。
注：英语不说 agree sb to do sth。如不说：
* She agreed me to go home.
3. agree on [upon]
(1) 主要指双方通过协商而取得一致意见或达成协议。如：
Can we agree on a price (a date)?
我们能不能商定一个价格(日期)?

注：在正式文体中，有时可省略介词 on。如：
Can we agree a price (date)?
(2) 后接动名词，表示同意做某事。如：
He agreed on helping us. 他同意帮助我们。
注：与 agree to do sth 大致同义。所以上句也可说成：
He agreed to help us.
