4、1when引导定语从句的用法(1)当先行词是表示时间的名词(如time, day, year, month, week等)，且关系词在从句中作时间状语时，定语从句用when引导。(2)when可以换成“介词which”。Winter is the time of year when (in which) the day is short while the night is long.冬天是一年中昼短夜长的时候。She is looking forward to the day when(on which) her daughter wins a gold medal at the Olymp
5、ics.她盼望有一天她的女儿能在奥运会上赢得金牌。 名师点津当先行词是表示时间的名词时，既可以用when引导定语从句，也可以用that或which引导定语从句，关键要看关系词在定语从句中作何种成分。若关系词在定语从句中充当状语，则用when引导；若关系词在定语从句中充当主语或宾语，则用that或which引导。Do you still remember the days (that/which) we spent together on the farm？你还记得我们一起在农场度过的那些日子吗？(that或which作spent的宾语)Do you still remember the day

9、und where(in which) we can buy some fruit?附近有没有一个商店可以让我们在里面买些水果？(2)where引导状语从句时，为从属连词。where引导的地点状语从句修饰主句中的谓语动词，where前面没有表示地点的名词。此时，where不能换成“介词which”结构。where引导的地点状语从句可位于主句之前，也可位于主句之后。Where there is a will，there is a way.(谚)有志者，事竟成。We should go where we are needed.我们应该到需要我们的地方去。 即学即练2(1)Their child i

12、点津若先行词为reason，且关系词在定语从句中不作状语，而是充当主语或宾语，则用that或which引导定语从句。The reason that/which he told me yesterday is a lie.昨天他告诉我的理由是个谎言。 即学即练3语法填空(1)There are several reasons _ school uniforms are a good idea. First of all, uniforms help the school look smart.(2)However, there are a number of other reasons _ mi
13、ght explain why you want to garden.二、“介词关系代词”引导的定语从句1关系代词的选择“介词关系代词”既可以引导限制性定语从句，也可以引导非限制性定语从句。在此结构中，先行词指人时关系代词用whom，不可用who/that；先行词指物时关系代词用which，不能用that。This is the student for whom I bought a book.这就是我给其买书的那个学生。This is the ship by which I went to Shanghai.这就是我去上海所乘的船。The film in which he played th

16、)根据句子的意思来确定介词。有些句子中，定语从句中的谓语动词/主要形容词与介词也不能构成固定搭配，这时，需要根据句子所要表达的意思来选择介词。This is the pilot with whom my brother has worked for ten years.这就是和我弟弟一起工作了十年的那位飞行员。This kind of colorless gas without which we cant live is called oxygen.这种无色气体被称作氧气，没有它我们就不能生存。3介词可以后移，此时关系代词可以省略(省略时，介词必须后移)。This is the book fo
17、r which you asked.这是你要的那本书。This is the book(which/that)you asked for.这是你要的那本书。 名师点津有些固定的动词短语一般不能拆开，介词一般只能放在动词的后面。4在“介词关系代词”结构中，介词也可换成介词短语，如by means of, because of, at the foot of, at the back of, in front of, on the top of等。若介词短语表示位置，则定语从句往往用倒装语序。Sound is a tool by means of which people communicate
