nevertheless,but和however的比較：
（1）but用來引出相反的意見,是口語常用語,如：sally was amused,but i was very embarrassed.薩莉很開心,但我卻很尷尬.
（2）however比but的詞義要弱些,并不直接引出相反的意見,因此常用作插入語,如：the most surprising thing about it,however,is that it can land anywhere.不過,答案〖but〗解析：關(guān)于這架飛機最使人吃驚的事情是,它可以在任何地方著陸.
(3)nevertheless的含義為即使做出完全的讓步,也沒有任何影響,或者說也不是決定因素,如：there was no news；nevertheless,she went on hoping.一點消息也沒有,但她仍抱著希望.
還有一些例句：
nevertheless
ad.
1. 仍然,不過,然而
She was angry; nevertheless, she listened to me.
她很生氣,但還是聽了我的話.
We can't act on your advice. Nevertheless, thank you for giving it.
我們不能照你的建議去辦.不過承蒙您提出來,十分感謝.
