教学课件 冀教英语八年级下册 Unit6 语法专项—— 宾语从句 全解精讲+分层练习 1 学习目标 理解宾语从句的概念与基本构成 掌握三类宾语从句的引导词用法 牢记宾语从句必须使用陈述语序 熟练掌握主从句时态呼应规则 能在单选、填空、改写等题型中正确运用 宾语从句定义 在复合句中充当宾语成分的句子 作主句动词或介词的宾语 用来表达想法、感受、疑问等内容 由引导词+主语+谓语构成 完整结构:主句 + 引导词 + 宾语从句 宾语从句的三大类型(一) 陈述句转化为宾语从句 引导词:that that无实际意义,口语中可省略 从句语序保持陈述语序不变 例句:He says (that) he is busy. 宾语从句的三大类型(二) 特殊疑问句转化为宾语从句 引导词:what, who, when, where, why, how 保留原来的特殊疑问词 从句必须改为陈述语序 例句:I know where he lives. 宾语从句的三大类型(三) 一般疑问句转化为宾语从句 引导词:if / whether,表示“是否” if与whether常可互换 从句必须改为陈述语序 例句:I wonder if you are right. 引导词用法总表 从句类型 引导词 用法 陈述句 that 无词义,可省 特殊疑问句 what/when/where等 保留疑问含义 一般疑问句 if/whether 表示“是否” 宾语从句核心规则—语序 所有宾语从句一律使用陈述语序 陈述语序:主语 + 谓语 绝对不能使用疑问语序 错误:I don’t know where is he. 正确:I don’t know where he is. 语序易错点提醒 what、who等词作从句主语时,语序不变 例句:I don’t know what happened. 例句:She asks who is in the room. 只有疑问词作状语/定语时才需要调整语序 宾语从句核心规则—时态呼应 主句是一般现在时 从句可根据需要使用任意时态 例句:I know he works here. 例句:I know he is working now. 例句:I know he will come tomorrow. 时态呼应(主句过去时) 主句是一般过去时 从句必须使用过去的某种时态 一般过去时、过去进行时、过去将来时等 例句:He said he lived here. 例句:She said she would go. 时态特例—客观真理 从句内容是客观真理、自然规律 无论主句什么时态,从句永远用一般现在时 例句:The teacher said the earth goes around the sun. 例句:He told us that light travels fast. if 与 whether 的区别 两者都表示“是否”,常可互换 以下情况只能用whether 与or not直接连用时:whether or not 在介词之后时:I worry about whether… 与不定式连用时:I don’t know whether to go that 的特殊用法 that在从句中不充当成分 只起连接作用,可省略 当从句有多个并列时,第一个that可省 后面的that不可省略 例句:I think (that) you are right and that he is wrong. 常见动词后接宾语从句 say, think, believe, hope, know understand, wonder, ask, answer tell, show, learn, remember, forget 这些词后常直接接that/if/wh-从句 常见介词后接宾语从句 介词后可接宾语从句 多用wh-引导词,一般不用that I’m interested in what he said. I worry about whether she will come. 宾语从句解题三步法 第一步:根据句意选引导词 第二步:检查从句是否为陈述语序 第三步:根据主句时态确定从句时态 最后核对句意是否通顺 单项选择 1.Do you know _ he will come tomorrow?
