2024-2025学年人教版九年级英语全册 定语从句讲解与练习（含答案）

九年级语法：定语从句 定义： 对名词和代词起限定修饰作用的从句就是定语从句 定语的作用 位置： 2个单词的定语要后置， 从句至少有两个单词 所以定语从句的位置在所修饰的名词或代词后 类型： 限制性定语从句 限定修饰先行词的定语从句， 是句子不可缺少的组成部分。 先行词和定语从句之间没有逗号隔开。 非限制性定语从句 对先行词的补充说明， 没有也不影响主句意思的完整。 先行词和定语从句之间须用逗号隔开。 一、限制性定语从句： 定语从句修饰限定的词叫先行词 (先于定语从句出现的名词/代词) >主句&从句的区别： 从句有引导从句的词 引导定语从句的词叫关系词 (关乎联系到主句和定语从句， 指代先行词在从句中充当成分) eg: 莉莉是一个有着长头发的美丽女孩。 Lily is a beautiful girl who has long hair. 先行词 关系词 从句 *who 在此处指代先行词 girl， 在从句中充当主语 把该句话拆解为2个简单句： Lily is a beautiful girl. She has long hair. 1.结构： ……+先行词 关系词+从句 注意：定语从句 (翻译为“……的”) 2.关系词： 关系代词 ( that、 which、 who、 whom、 whose、 as) 关系副词 ( when、 where、 why) （1）关系代词 (有人和物之分) 在从句中可作主语、宾语、表语、定语 关系代词 先行词 关系代词充当成分 例句 that 人/物 主语 宾语 表语 The people that/ who come to visit this city are all Chinese. ( that在从句里作主语) which 物 主语 宾语 . Football is a game which is liked by most boys. ( which在从句里作主语) who 人 主语 宾语 The boys who are playing football are from Class One. ( who在从句里作主语) whom 人 宾语 Mr. Su is the person ( whom) you talked about. whose 人/物 定语 He has a friend whose father is a doctor. 注意 1： >关系代词作宾语可省略， 作其他成分不可省略。但紧跟在介词后的关系代词不可省略。 >介词后的关系代词只有 which (物) 与 whom (人) , 不能用 that和 who作宾语。 > whose后紧跟名词。 注意 2：只能用 that, 不能用 which/ who/ whom的情况: (1)先行词同时含有人和物时 I can remember the people and buildings ( that) I saw in Beijing. (2)先行词被序数词修饰时 He was the second person that got to the classroom. (3)先行词被最高级修饰时 John is the strongest man that I know. (4)先行词是指物的不定代词时(如 something/ anything/ nothing/ everything/ the one/ all等) Is there anything that you want to buy in the market (5)先行词被 the only, the very, the same, the last修饰时 Lee is the only person that I know in our class. (6)先行词所在的主句是 who/ which开头的句子时 Who is the girl that is singing 注意 3：用 who,而不用 that的一些情况 (1)先行词是 one， anyone等指人的不定代词时。 One who has nothing to fear for oneself dares to tell the truth. Don't tell anyone about the news who oughtn't to know it. (2)先行词是 those时 Those who helped us in trouble should be remembered. 注意 4：the way(先行词) +定语从句, 有三种表达形式: (1) the way + that (2) the way + in which (3) the way + 从句(省略了 that 或 in which) eg: I never like the way( in which/ that) he speaks to you.我不喜欢他和你说话的方式 (2)关系副词在从句中作状语， 关系副词可变成“介词+关系代词”的形式 关系副词 →介词+关系代词 先行词 充当成分 例句 when→in/ on/ during which 时间 时间状语 I' ll never forget the day when ( on which) I met you. 我永远不会忘记遇见你的那天 ... ...
