last.最后他同意了我们的计划。They agreed to come on Monday.他们同意星期一来。,Do you agree with my ideas?你同意我的观点吗？,agree on 表示“(两人以上)就 取得一致意见，在方面意见一致”，其主语多为复数形式，宾语是表示事、计划等的名词，而不是表示人的名词或代词，它可以与agree in doing sth.替换。e.g.They agreed on the plan.=They agreed in doing the plan.他们对这个计划意见一致。,特别提示agree with 也可以表示“某人适应（食物、气候等）”。The weather doesnt agree with me.我不适应这种天气。,
