语法专题之宾语从句

语法专题之宾语从句宾语从句三注意，时态语序引导词；主句一般现在时，从句不需受限制；主句一般过去时，从句须用相应时；陈述句转化that弓I，一般疑问句用if/whether,特殊问句疑问词，弓I导词后陈述式一、基本讲解1概念:在句中担当宾语的从句叫宾语从句， 宾语从句可作谓语动词的宾语，也可做介词的宾语eg, He said he was good at drawing.(动词宾语)He asks him how long Mike has been down .( 动词宾语)Miss Zhang is angry at what you said.(介词宾语)2. 连接词(1).陈述句转化成宾语从句时，引导词用 that, 口语中常常省略e.g, She told me (that) she would like to go with us.⑵以whether或if引导的宾语从句，主要用来引导一般疑问句意思或选择疑问句意思的 宾语从句，从句同样是陈述语序eg, I won der if /whether u have told the new to Li Lei .注意：一般情况下，whether和if可以互用，但有些情况例外。

a. 当从句做介词的宾于是只用whether不用ifeg, We are talk ing about whether we'll go on the pinic.b. 引导词与动词不定式或not连用时，只用whether.eg, Please let me know what to do n ext.Could you tell me whether u go or not?c. if当如果讲时，引导的是条件状语从句， 这时不能用whether.(3).特殊疑问句转化成宾语从句时，引导词用特殊疑问词；引导词后要用陈述句语序E.g. Could you tell me what's the matter\wrong with you?特殊情况：：当do you think后接特殊疑问句转化成宾语从句时，句式结构应为引导词 + do you thi nk +陈述句语序3. 宾语从句时态a. 当主句是一般现在时，一般将来时或祈使句时，从句不受主句的限制，根据自身的需要选 用相应的时态例如： Do you know (if/whether he has seen the film ) ?b. 当主句是一般过去时，从句要用过去时的相应时态。

例如：I did n't know (if/whether he had see n the film.)注意：当主句是一般过去时，而从句表示的是客观真理，自然现象，科学原理，格言等，从 句仍然要用一般现在时例如： He said (that the earth moves round the sun.)The teacher told us (that light travels much faster than sound.)4. 、人称的变化和标点的使用a.从句的主语如果是第一人称，变为宾语从句则与主句的主语一致；如果是第二人称，则与 主句的宾语一致；如果是第三人称，不用变化如：“ May I use your knife? ” He asked me.t He asked me if he might use my knife.“ Do you know her telephone number？ ” He asked me.t He asked me if I know her teleph one nu mber.b. 宾语从句的标点均由主句决定主句是陈述句，用句号；主句是疑问句，用问号。

如：Who will give us a talk? I don 't know. tI don 't know who will give us a talk.Do you know ？ Where does he live? t Do you know where hes?live二、宾语从句的转化1.2. 当主句谓语动词是 hope，wish，decide，forget，plan，agree 等，且主句主语与从句主语相同时，从句可简化为不定式结构如：She agreed that she could help me with my maths.t She agreed to help me with my maths.2. 当主句的谓语动词是 know, learn, forget, remember, decide 等后面带特殊疑问句转化的宾语时，主从句的主语也须一致这时从句可以简化成 “疑问词＋不定式结构 ”例如：I don't know which sweater I should buy. t I don't know which sweater to buy.3. 当主句的谓语动词是 ask，tell, show, teach 等后面带双宾语时， 从句的主语和间接宾语一致，且从句是由特殊疑问句转化来时，从句可以转化成 “疑问词＋不定式结构 ”或,者在连接代词 / 副词引导的宾语从句中，当从句主语与主句主语或间接宾语一致时，宾语从句可简化为 “连 接代词 /副词＋不定式 ”结构。

如： tCould you tell me how to get to the park?4. 当主句谓语动词是find , see, watch, hear等感官动词时，从句常简化为 宾语+宾补"结构，宾补为不带 to 的不定式或 V-ing 形式如：She found that the wallet lay/was lying on the ground.t She found the wallet lie/lying on the ground.试试看,你都学会了吗？ 语法巩固练习一、单项选择题1.
