Grammar——限制性定语从句与非限制性定语从句 语法精讲 一、基本概念 根据定语从句与先行词之间关系的疏密程度，定语从句分为限制性定语从句和非限制性定语从句。 限制性定语从句：限制性定语从句是先行词在意义上不可缺少的定语，用于修饰和限定先行词。如果去掉，主句的意思就不完整。 The woman who/that survived the earthquake is Amy’s English teacher. 在地震中幸存的那个女人是埃米的英语老师。 非限制性定语从句：非限制性定语从句和主句的关系不是十分密切，只是对先行词或主句作附加说明，如果去掉，主句的意思仍然完整。这种从句和主句之间往往用逗号分开。 Our foreign teacher，who is a Canadian，teaches us in a very interesting way. 我们的外教，一个加拿大人，用很有趣的方式给我们上课。 二、语法规则 (一)限制性定语从句与非限制性定语从句的区别 项目 限制性定语从句 非限制性定语从句 形式 与先行词之间不用逗号隔开 与先行词之间一般用逗号隔开 功能 与先行词的关系十分密切，限制了先行词的意义。如果去掉该从句，剩余部分的意思往往不完整，甚至失去意义 是先行词的附加说明，如去掉，句子剩余部分的意思仍然完整 先行词 先行词一般为单个的名词或代词 先行词既可为单个的名词或代词，也可为整个句子或其中一部分 引导词 可用所有的关系代词/副词引导，且关系词作宾语时可省略 在所有的关系词中不能用that或why引导非限制性定语从句，且其他引导词不能省略 It was a woman，pushing an old shopping trolley which was piled with bags.(which引导限制性定语从句) 那是一位女士，推着一辆装满袋子的破旧购物车。 During the rosy years of elementary school，I enjoyed sharing my dolls and jokes，which allowed me to keep my high social status.(which引导非限制性定语从句) 在美好的小学时光里，我喜欢分享我的玩偶和笑话，这让我保持了较高的社会地位。 [温馨提示] (1)在非限制性定语从句中，关系代词作宾语时不能省略，关系代词指人时，只能用whom，不能用who。 (2)关系代词that不引导非限制性定语从句。 (3)关系副词where和when可以转换成相应的介词＋which。 [对点集训1] 用适当的关系词填空 ①My eldest son，　whose work takes him all over the world，is in New York at the moment. ②They are interested in planting vegetables in their garden，　which is on the rooftop of their house. ③But Sarah，　who has taken part in shows along with top models，wants to prove that she has brains as well as beauty. (二)使用非限制性定语从句需要注意的几个问题 1．关系副词why不能引导非限制性定语从句，但可用for which代替why来引导。 He didn’t tell us the reason，for which he went abroad without telling anybody. 他没有告诉我们理由，为此在没有告诉任何人的情况下就去了国外。 2．非限制性定语从句由“介词＋关系代词”引导时，其中的关系代词用which或whom。 Lin­Manuel Miranda wrote this musical about Alexander Hamilton，in which the birth of America is presented as an immigrant story.　 林－马努艾尔·米兰达写了一部关于亚历山大·汉密尔顿的音乐剧，该剧将美国的诞生描绘成一个移民故事。 Our class is made up of 52 students，all of whom are hard­working and friendly. 我们班由52名学生组成，他们都非常刻苦和友好。 3．非限制性定语从句的关系代词无论指“物”还是指“人”，都不能用that。指人时，如果关系词在从句中作主语，则用who，作宾语用whom或who均可；指物时要用which。关系代词在从句中作宾语也不能省略。 Bechtel，who works in downtown West Palm Beach，has lunch with coworkers sometimes，but like many of us，too often works through lunch at her desk. 柏克德在西棕榈滩市区工作，她有时会和同事一起吃午饭，但和我们很多人一样，她经常在办公桌旁工作到午餐时间。 I ran into/across an old friend of mine in the street，whom I haven’t met for years. 我在街上碰见了我的一个老朋友，我已经好多年不见他了。 The book，which my mother bought for me yesterday，is very interesting. 这本书很有意思，这是我妈妈昨天为我买的。 4．as，which引导非限制性定语从句的区别。 项目 as which 指代 引导的从句只能指代整个主句的内容 引导的从句既可指代整个主句的内容，又可指代主句的一部分 位置 可位于主句之前、之中或之后 引导的从句不能位于主句之前 意义 正如 这，那 功能 起连接上下文的作用，表达说话人的观点、看法，并指出主句内容的根据或出处等 引导的从句在意义上相当于一个并列句 As we all know，friends are the family we choose for ourselves. 众所周知，朋友就是我们为自己选择的家人。 Consequently，she succeeded in making a kind of candy only using natural sweeteners，which can reduce oral bacteria. 因此，她成功地用天然甜味剂制造了一种可以减少口腔细菌的糖果。 [对点集训2] 单句语法填空 ①We’ve planned to hold an English Drama Festival，the theme of which is Love English & Love Drama. ②Then he was sent to study at Cambridge University，　from which he graduated in 1831. ③　As is known to us all，Chinese people would like to put up pictures to celebrate the Spring Festival. ④They went farther north into the deep forests of Canada，　where there were fewer humans around.
