however和nevertheless均可表示無論如何，不管怎樣。可作副詞也可用作連詞。however多插在句中,有時(shí)也放在句首或句尾。nevertheless指盡管作出完全讓步。

1.however表轉(zhuǎn)折關(guān)系，語氣稍弱于but，連接性也弱一些，因而常作插入語。however多插在句中,有時(shí)也放在句首或句尾,但都應(yīng)緊跟在進(jìn)行對比的詞或短語之后,用逗號將其與其他詞分開。

2.however的內(nèi)涵更多，用法更靈活,nevertheless使用使用范圍較窄。

3.however可作副詞，也可作連詞。

He can answer the question however hard it is.

不管問題有多難他都能回答。

However did you get here?

你是怎么到這里來的?

He hasn't arrived. He may, however, come later.

他還未到，不過，他可能過一會兒來。

4.nevertheless可作副詞，也可作連詞。nevertheless指盡管作出完全讓步，也不會發(fā)生任何影響。

She was very tired, nevertheless she kept on working.

她雖然很疲倦，可仍在繼續(xù)工作。

He's stupid, but I like him nevertheless.

他是很笨，然而我喜歡他。
