人教版九年级语法总结表 Unit 8: It must belong to Carla. 语法总结模块 1. 情态动词表推测的用法 语 法 点 核心规则 例句 考点提示 含 义 情态动词是用来表达说话人的情感、态度或语气，对动作或状态进行各种限 定。情态动词本身有一定的词义，但不能独立作谓语，必须和其他动词一起构成谓语。英语里能用于推测、表达可能性的情态动词有can、could、may、 might、must。 It must belong to Carla. 表示推测的程度不同 肯 定 推 测 must: 基于客观证据、逻辑的强肯定推测。 may/might/could: 语气依次减弱，意为"可能，或许"，用于肯定句或否定句(might/could更显不确定)。 He knows all the answers. He must have studied hard. My uncle may/might come back this afternoon, but I'm not sure. must表示非常肯定的推测， may/might/could表示可能性较低的推测 否 定 推 测 can't: 语义是"逻辑上不可能"，基于事实、常识直接否定。 may not/might not: 语义是"不太可 能"，可能性低但存在理论可能，说话者对否定结果没十足把握。 A baby can't solve this difficult math problem. He may not come to the party. He has a lot of work. can't表示非常肯定的否定推测， may not/might not表示可能性较低的否定推测 疑 问 推 测 只有can和could可用于疑问推测，表对情况的疑问性猜测。can / could用于疑问推测时，can更直接、口语化，could更委婉、礼貌。 Can this be the right path? Could there be another reason? 疑问句中只能用can和could表示推测 不 同 时 1. 情态动词+动词原形：对现在或将来事情的推测。 2. 情态动词+be+动词-ing形式：对正在 1. This book must be Tom's. 2. He must be 根据不同的时间使用不同的结构 态 的 推 测 结 构 发生事情的推测。 3. 情态动词+have+过去分词：对过去事情的推测。 doing his homework. 3. She might have seen the book yesterday. 常见错误分析 错误： He may be at home, but I'm sure. 正确： He must be at home, and I'm sure. 修正说明：既然说话者很确定，就应该用must而不是may。 Unit 9: I like music that I can dance to 语法总结模块 1. 定语从句 语法点 核心规则 例句 考点提示 定义 在复合句中，修饰某一名词或代词的从句叫做定语从句。定语从句所修饰的词叫先行词。定语从句放在先行词后面。定语从句结构为"先行词+关系词+从句"。 I like music that I can dance to. 定语从句修饰先行词 关系代词 关系代词有：that, which, who, whom, whose。它们在定语从句中可以作主语、宾语或定语。 1. that/which指物，在从句中作主语或宾语。 2. who/whom指人， who在从句中作主语， whom作宾语。 3. whose指人或物，在从句中作定语。 关系代词在从句中充当成分 用that不用which的情况 1. 当先行词既有指人，又有指物的名词时。 2. 当先行词是some, any, all, none, everything等不定代词或被不定代词修饰时。 3. 当先行词是形容词最高级、序数词或被这类词修饰时。 4. 当先行词被the same, the only, the very, the next, the last修饰时。 5. 当先行词前面有who, which等疑问代词时。 1. Cindy is looking at the things and people that are around her. 2. You can borrow any book that you are interested in. 3. This is the biggest box that I can find. 4. She was the only student that passed the exam. 5. Who was the girl that waited for the bus with you? 这些情况下只能用that不能用 which 用which不用that的情况 1. 非限制性定语从句中。 2. 先行词是that时，为了避免重复。 3. 在定语从句中作介词的宾语时。 1. He won the game, which made us very happy. 2. What's that which is next to my dictionary? 这些情况下只能用 which不能用that 3. I forgot the date on which we met. 先行词指 人时，关 系代词的使用 先行词指人时，关系代词用(who)作主语或宾语，whom(作宾语), whose(作定语), that(作主语或宾语)。 This is the policeman who/whom they were talking about yesterday. who和that在指人时通常可以互换 用who不 用that的情况 1. 先行词是指人的不定代词时(如：one, ones, anyone, nobody, everyone等)。 2. 先行词是指人的those。 3. There be结构中主语是指人的名词。 1. He was the one who broke the window. 2. Those who are in trouble need some advice. 3. There were two women who wanted to see you. 这些情况下只能用who不能用that 关系副词 关系副词有：when, where, why。它们在定语从句中分别做时间状语、地点状语和原因状语。 I still remember the day when we met for the first time. 关系副词在 从句中作状语 介词+关系代词 "介词+关系代词"可替换关系副词： when=on/at/in/during which; where=in/at which; why=for which。 I will never forget the day when(on which)I went to university. 介词的选择 取决于先行 词或从句中 的动词搭配 选择技巧 从句缺少成分，则选择关系代词；从句不缺成分，则选择关系副词。 I will always remember the days that we spent together. (从句缺宾语，用关系代词) I will always remember the days when we studied together. (从句不缺成分，用关系副词) 根据从句是否缺少成分来选择关系词 非限制性定语从句 非限制性定语从句是对先行词的补充说明，去掉后不影响句子的基本意思。非限制性定语从句和主句之间用逗号隔开。 例如： My brother, who is a doctor, lives in Beijing. 注意：在非限制性定语从句中，不能用that引导，指人用who/whom，指物用which。 学科网（北京）股份有限公司 $
