定语从句 应注意的几个方面 * 一、定语从句中宜用that，不宜 用which的情况： 在定语从句中，which和that在指代事物时，一般可以互换使用，但并非在任何情况下都是这样。 １、被修饰的先行词为不定代词时，宜用that。 We should do all that is useful to the people. Theres nothing that can be said about it. Do you mean that one that was bought  yesterday? ２、先行词被only, any, few, little, no, all, one of, just, very等词修饰时，宜用that。 The only thing that we could do was to wait. You can take any seat that is free. Thats the very word that is wrongly used. This is one of the presents that my boy friend  gave me on my birthday. ３、先行词时序数词或被序数词修饰时，宜  用that。 When we talk about Wuxi, the first that  comes into mind is Tai Lake. This is the third film that has been shown  in our school this term. ４、先行词是最高级或被最高级修饰时，宜 用that。 The most important thing that should be  done now is how to stop him from going on. ５、先行词既有人又有物，用which和who都不合适，这时宜用that。 The writer and his novel that you have just  talked about is really well known. The bike and its rider that had run over an  old woman were held up by the police. ６、被修饰词为数词时。 Yesterday I caught two fish and them in a  basin of water. Now you can see the two  that are still alive. ７、如有两个从句，其中一个关系代词已用 which，另一个关系代词则宜用that，以 避免语言的单调或重复。 Edison built up a factory which produced  things that had never been seen before. ８、主句是There be结构，修饰其主语的定 语从句宜用that作关系代词。 Theres still a seat in the corner that is still  free. ９、被修饰成分为表语，或者关系代词本身是定语从句的表语时，该关系代词宜用that。 Thats a good book that will help you a lot. 二、定语从句中宜用which而不宜用that的情 况 １、当关系代词前面有介词时。 A zoo is a park in which many kinds of  animals are kept for exhibition. Is this the room in which Mr White lives? ２、在非限制性定语从句中。 Crusoes dog, which was now very old,  became ill and died. ３、在一个句子中有两个定语从句，其 中一个从句的关系代词用了that， 另一个宜用which。 Let me show you the novel that I borrowed  from the library wh
