They might not agree with his opinions. his opinions不是sth吗?为

看来你是误以为agree with sb,其实不是的.
下面的是我的教案,你来看看,不懂可追问.
有关agree “(同意；赞成”)的词组的比较：
○1agree with：
a.“同意某人的意见/同意…”.with后可接sb,也可接sth..如 I really agree with you. // Do you agree with the idea / what I said?
b. 当物作主语时,译作“适合”.如 The weather here doesn’t agree with me.
○2agree to：“同意…”.to后接表示计划(plan)、决定(decision)的词.如 They agree to your plan / decision.
○3agree on：“就…达成一致”.如 All of us agreed on the time.
○4此外,agree还可接不定式作宾语,即agree to do.同时,agree还可接宾语从句.如 He agrees to help me carry the table. / The teacher agreed that Alice could go home first.
希望我的回答能够帮到你,望采纳!
