agree
1.agree作“承认”解，后面可以接以that引导的从句，如I agree (with you) that the book is well worth reading。
2.agree with是“同意”，后面接指人或表示“意见”的词，如I agree with you和I agree with what you say。agree to是“应允”或“同意于”，后面接表示“提议”、“办法”、“计划”等的词，如I agree to the proposal和Does he agree to this arrangement? agree on（或upon）是“（双方）决定”，如They agree (up) on these terms。近年来往往省去agree后面的to或on （或upon），把agree用作及物动词。
3.We are agreed里的agreed（互相同意的）是不及物动词的过去分词用作形容词，后面可以接以that引导的从句，如We are agreed that the meeting must be held not later than 8 August。We met at an agreed place at an agreed time和A joint declaration agreed by all the governments concerned will soon be published里的agreed是及物动词的过去分词。
4.They agreed to do it是“他们（听从了别人而）同意做这件事”，They agreed in doing it是“他们对于做这件事互相同意。”
5.下面三句意思相同：
- I agree that he call on me every Sunday.
- I agree that he shall call on me every Sunday.
- I agree that he should call on me every Sunday.
注意第一句里用call（虚拟现在式），不用calls。
下面两句意思相同：
- I agreed that he call on me every Sunday.
- I agreed that he should call on me every Sunday.
注意第一句里用call，不用called。
比较下面两句（参见1）：
- I agree that he call on me every Sunday. （我赞同他每星期日来访。）
- I agree that he calls on me every Sunday. （我承认他是每星期日来访的。）
