英语中的that和which都可以用来引导定语从句,但在某些情况下,只能使用that而不能使用which。下面是一个简单的顺口溜,帮助大家记住这个规则:
"That, that, that, 不要用which。
指物叫that,指人用who。
句子简单用that,逗号先which后that。"
这个顺口溜的意思是,当你在描述一个物体时,应该使用that而不是which。当你在描述一个人时,应该使用who。如果你的句子很简单,可以使用that。如果你需要在定语从句中使用逗号,应该先使用which,然后再使用that。
下面是一些例子,帮助你更好地理解这个规则:
这是我买的书,它非常有趣。
This is the book that I bought, and it is very interesting. (正确) This is the book which I bought, and it is very interesting. (错误)
我喜欢的歌手是麦当娜。
The singer who I like is Madonna. (正确) The singer which I like is Madonna. (错误)
我需要一件黑色的衬衫,它的尺寸是中等的。

我的爸爸是一个律师,他经常去出差。

记住这个顺口溜,并在写作和口语中使用它,可以帮助你更好地掌握英语定语从句的使用。
