下面來看幾個(gè)連接副詞在作副詞和連詞時(shí)的區(qū)別：

However

however 作副詞時(shí)，可位于形容詞/副詞之前：

You couldn’t earn much, however hard you worked.

無論你干得多賣力，你都掙不了多少錢。

however 作連詞時(shí)通常意為“但是”，可位于它所引導(dǎo)的從句之前或之后，或位于第一個(gè)詞或短語之后：

I’ll offer it to Tom. However, he may not want it. / He may not want it however. / Tom, however, may not want it.

我將提出把這個(gè)給湯姆，然而他可能不要它。

但提到兩句意義相反的話時(shí)， however意為“但是/仍然/同樣”：

They hadn’t trained hard, however ( / but / nevertheless / all the same) they won.

他們并沒有刻苦訓(xùn)練，但/無論如何/仍然/同樣獲勝了。
