长风破浪会有时，直挂云帆济沧海。 Unit 5-6单元语法讲解及综合练习—宾语从句 一、定义 宾语从句是英语中用来充当宾语的句子，放在动词/介词后面。 结构：主语 + 谓语 + 引导词 + 宾语从句 二、宾语从句的三要素：引导词 + 时态 + 语序 考点一：三大引导词 (1) that引导的宾语从句 当从句为陈述句时，用that引导；无词义，可省略。 原 句 ①I know it. ②The party is really fun.（陈述句） 宾语从句 I know (that) the party is really fun. 常接that引导的宾语从句的主句动词：believe, tell, say, see, think, know, expect, feel, hear, hope, imagine, prefer, promise, report, understand, warn, wish, tell sb. sth.（表确定的概念） 注意1：否定前置 主句主语为 I / We，谓语为 think, suppose, believe, guess, expect时，若后面的句子表否定概念，一般将否定词not转移到主句的谓语中。即“否定转移”。 I think it will not rain tomorrow. ❌ I don't think it will rain tomorrow. ✅ 注意2：that在宾语从句中的保留 并列连词连接的两个以上的that引导的宾语从句，第1个that 可省去，其余的that都保留。 He said (that) the book was very interesting and that (不省略) all the kids liked it. (2) if / whether引导的宾语从句 当从句表不确定的概念时，用 whether/if 引导；表“是否”，不可省略。 原 句 ①I want to know it. ②Does he live there?（一般疑问句） 宾语从句 I want to know whether/if he lives there. 常接whether引导的宾语从句的主句动词：wonder, don't know, want to know, doubt, be worried about, ask, see, Could you tell me…（表不确定的概念） 注意：只用 whether不用 if的三种情况 1.句子有or not：I don’ t know whether or not he will come. 2.在介词后：I’ m interested in whether he will come. 3.动词不定式前：He will tell us whether to take a break. (3) 特殊疑问词引导的宾语从句 当从句为特殊疑问句时，用特殊疑问词(wh- / how... )引导；有词义，不可省略。 原 句 ①I want to know it. ②Where does he live?（特殊疑问句） 宾语从句 I want to know where he lives.（引导词用原句特殊疑问词） 特殊疑问词可以是疑问代词what、who、whom(宾格)、whose(谁的)、which和疑问副词when、where、how、why等, 它们在从句中充当主语、宾语、表语、定语、状语等，不省略。 考点二：语序 宾语从句一律用陈述语序（主语+谓语），无论主句是陈述句还是疑问句。 I don’ t know where does he live. ❌ I don’ t know where he lives. ✅ 考点三：时态 口诀：主现从不限，主过从必过，真理永一现。 主句时态 从句时态 例子 主句为一般现在时 从句根据需要，可用任意时态 She knows where he lives. 主句为一般过去时 从句用相应的过去时态 He said he was tired. 从句为客观真理，或不可改变的自然现象, 从句用一般现在时 The teacher told us the earth goes around the sun. 主句是过去时 → 从句时态变化规则： 一般现在时 do →一般过去时 did 一般将来时 will do →过去将来时 would do 现在进行时 am/is/are doing →过去进行时 was/were doing 现在完成时 have done →过去完成时 had done 练习题 (考点：语序、引导词、时态、否定前移、客观真理) 一、判断对错并改正（最多一个错误） 1.
