北师大高中英语模块1Unit3Lesson3: When my sister got married last year, my mum and sister did not agree on anything.中agree on的用法？

解释：

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：

We agreed on the question. 我们在这个问题上意见一致。

②后接动名词 (=agree to do sth)：

They agreed on leaving [to leave] there the next day. 他们一致同意第二天离开那里。

比较：

1. agree with

①表示同意某人或某人的意见等。（宾语通常为sb, opinion, view, idea, what sb said…）

In the main, I agree with you. 我基本上同意你的意见。

They might not agree with his opinions. 他们或许会不同意他的意见。

Do you agree with what he said? 你同意他说的吗?

②表示“ (食物、天气、工作等)对…适宜”：

The climate here agrees very well with me. 此地的气候很适合我。

③表示“与…一致”：

His explanation agrees with the facts of the situation. 他的解释与实情相符。

2. agree to

①主要用来表示一方提出一项建议、安排、计划等，宾语通常为：suggestion, plan, proposal，arrangement等。

We agreed to their arrangement. 我们同意了他们的安排。

We agreed to their proposal. 我们同意了他们的建议。

②后可接动名词(一般有逻辑主语)：

He agreed to our sending Jack to Hong Kong. 他赞成我们把杰克派往香港。

He did not agree to Mary taking up the job. 他不赞成玛丽承担这项工作。

③后可接动词不定式：

He agreed to go with us. 他同意同我们去。

3. agree 不能接不定式的复合结构，所以汉语的“同意某人做某事”，不能直译为agree sb to do sth, 而应根据情况改用其它结构：

他们同意我去。

正：They agreed to let me go. 

正：They agreed to my going. 

误：They agreed me to go.
