在商務往來的交流中很多時候都會達不成共識，如果要表達不同意對方的意見有以下表達：

I'm sorry, I disagree with you there. I don't think that's the way with it.
對不起，我不同意你的看法。我認為那不是辦法。
This works against common sense. I don't go along with it for one minute.
這有悖常理，我一點也不同意。
I'm totally against the proposal of making transshipment at Hong Kong.
我完全反對在香港轉船的建議。
I wouldn't say that. I think it's only a matter of time.
我不認為如此，我認為這只是個時間問題。

I don't like the idea of substituting Type No. 15 for the portion undelivered.
我不同意未交貨部分改用15型代替。
It's absolutely impossible. I really can't accept the idea.
這完全不可能。我實在不能接受這個主意。
