首先,agree是动词 vt.& vi.同意 I asked him to come with me and he agreed. 我请他和我一起来,他同意了. vi.相符,一致 The essential thing is that the two of you ought to agree. 根本的问题是你们俩应意见一致. approve也是动词 vi.赞同,赞许(of) Don't expect him to approve of your plan straight away. 别指望他马上会接受你的计划. vt.批准（需要注意的是,“批准”和“赞同”是不一样的意思） The minister approved the building plan. 部长批准了该建筑计划. permission是名词 With your permission I'll leave now. 有你的允许,我这就离开.
