初中宾语从句讲解练习及答案.doc

1. 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. 宾语从句的引导词有三类: (1) 以 that 引导的宾语从句, 主要用来引导句形式的宾语从句, that 可以省略。 eg, The radio says (that) the clouds will lift later on. She told me (that) she would like to go with us. (2) 由连接代词 who, whom, whose, what, which 和连接副词 when, where, why, how 引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。从句是陈述语序 eg, Could you tell me what's the matter with u? I want to know how soon it will begin. (3) 以 whether 或 if 引导的宾语从句, If和 whether 在句中的意思是“是否”,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 wonder if /whether u have told the new to Li Lei . 3 .宾语从句的时态(1) 当主句为一般现在时态、现在进行时态、或一般将来时态时, 从句可用所需要的任何时态。 eg, I want to know what time he got up this morning. You are telling me that you won't stop until tomorrow? (2) 当主句为一般过去时态时, 从句要用于过去有关的时态。 eg,They asked what Jean was doing now . Linda said that the train had left. (3) 当从句表述的是客观真理或自然现象时,宾语从句要使用一般现在时。 eg, Lisa asked whether light travels faster than sound. Polly said no news isa good news 注意:一般情况下, whether 和 if 可以互用, 但有些情况例外。 1. 当从句做介词的宾于是只用 whether 不用 if eg, We are talking about whether we'll go on the pinic. 2. 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 next. Could you tell me whether u go or not? ③在不定式前用 whether 。如: He hasn't decided whether to visit the old man .他尚未决
