關系代詞which重要用法說明

■關系代詞which只用于指事或物，不用于指人，它在定語從句中主要用作主語或賓語。如：

She was not on the train which arrived just now. 她不在剛才到達的那列火車上。(關系代詞which指train，在從句中用作主語)

He never got back the money which he had lent him. 他從未收回他曾借給他的那筆錢。(關系代詞which指money，在從句中用作賓語)

■which用于引導限制性定語從句外，還可以引導非限制定語從句。如：

The ship struck an iceberg, which tore a huge hole in her side. 船碰在一座冰山上，船幫被撞出一個大洞。

She gave me this jumper, which she had knitted herself. 她送給我這件羊毛衫，這是她親手織的。

This machine, which I have looked after for twenty years, is still working perfectly. 這臺機器我已經照管了20年，現在仍然沒一點兒毛病。

■which有時也可用作定語，尤其用于“介詞+which+名詞”這類結構中，此時的which含有this或that的意味。如：

He may be busy, in which case I’ll call later. 他可能忙，如若如此，我以后再來拜訪。

I may have to work late, in which case I’ll telephone. 我可能得晚點下班，那樣我會打電話的。

It was derived from Posidonius, for which reason much of its information may well have been out of date. 它源于鮑森杜尼爾斯。由于這個原因，它的大部分信息很可能已經過時。

He spoke in Greek, which language I could only follow with difficulty. 他說希臘語，我聽起來很吃力。
