,根据所掌握的定语从句的知识，熟练地使用定语从句也是高考英语写作的一项基本要求。定语从句属于较为复杂的语法结构，根据内容要点在短文中适当地运用定语从句有助于提高写作的得分。,一、that, which引导定语从句 当先行词为物时常用that或which来引导定语从句，很多情况下两者可以互换。 Our class is a big family that/which consists of 12 girls and 50 boys. 我们班是一个拥有12个女生和50个男生的大家庭。,点津 that和which在从句中作宾语时可以省略。 To make our society more harmonious, we'd better take care of the environment (that/which) we live in. 为了使我们的社会更加和谐，我们最好爱护我们所居住的环境。,二、who, whom, whose引导定语从句 当先行词为人时常用who, whom引导，也可用that。如果从句中缺少的是主语那么就用who引导；如果缺少的是宾语可用whom，也可以用who引导，关系代词也可以省略。whose在从句中作定语，既可以指人，也可以指物。 Those who would like to take part may sign up in the Students' Union Office before October 20th. (作主语),凡想参加的(同学)可以在十月二十日前到学生会办公室报名。 Is that the man whom you referred to? (作宾语) 那就是你所指的人吗？ Last Sunday, I organized a survey in my neighborhood, whose topic is “Which safety problem is the one you are most concerned about”. (作定语) 上周日，我在我的社区进行了一次社会调查，其主题内容是“你最关注的安全问题是什么”。,三、as引导定语从句 as指人或物，作主语、宾语或表语。as引导定语从句时常用在the same .as, such .as结构中。 I want to buy the same Tshirt as Tom is wearing. 我想买一件和汤姆穿的一样的T恤衫。,点津 as和which还可以引导非限制性定语从句，来修饰整个句子。 As we can see, great changes have taken place in our hometown. 正如我们所看到的，我们家乡已经发生了巨大的变化。 Li Ming got up late this morning, which made it impossible for him to catch the early bus. 李明今天早上起晚了，这使他不可能赶上早班车了。,四、when引导定语从句 when指时间，作状语。 I will never forget the day when I joined the army. 我将永远不会忘记我参军的那一天。 点津 当表示时间的先行词在从句中不是作状语，而是作主语、宾语或表语时，必须用关系代词that或which引导定语从句，而不用when。 The film reminded me of those miserable days (that/which) I spent in my childhood. 这部电影使我想起了我童年时代度过的那些苦难日子。,五、where引导定语从句 where指地点，作状语。 As a child, he used to work hard and help his father on the small farm where they lived. 当他还是一个小孩的时候，他经常艰苦地劳动，并帮助他的父亲在他们所生活的小农场上干活。,点津 当表示地点的先行词在从句中不是作状语，而是作主语、宾语或表语时，必须用关系代词that或which引导定语从句，而不用where。 This is a beautiful place (that/which) people all over the world look forward to visiting. 这是一个世界各地的人都渴望参观的美丽的地方。,六、why引导定语从句 why指原因，作状语。 Nobody knows the reason why he is often late for school. 没人知道他为什么上学总迟到。 The reason why Tom didn't come to school yesterday was that he was ill. 汤姆昨天没来学校的原因是他生病了。,点击此图片进入“针对训练”,
