1、宾语从句复习三要点,重庆市铝城中学 廖小康,要点一:宾语从句的引导词,.当宾语从句是由陈述句变化而来时,该从句通常由that引导。此时that没有具体意义,口语中可以省略。例如:Im sure. You have seen that book before.(合并句子),Im sure (that) you have seen that book before.,2.当宾语从句是由一般疑问句变化而来时,用连词if或whether引导,意思为“是否”,表示选择。例如: Could you tell us ? Will he really come here ? (合并句子),Could you
2、tell us if / whether he will really come here ?,注意: if 和whether在引导宾语从句时,一般可以互换,但下列四种情况中只能用whether ,而不能用if 。,1)当和or not 一起使用时。例如: We didnt know whether or not she was ready.我们不知道她是否已做好准备。,2)宾语从句用作介词宾语时。例如: I am interested in whether he joined the army. 我对他是否参军了很感兴趣。,3)当宾语从句移到句首表示强调时。例如: Whether this
3、is true or not, Im not sure. 这是否真实,我不敢肯定。,4)连词处于动词不定式前,用whether而不用if。例如:We decided whether to walk there.,3.当宾语从句由特殊疑问句变化而来时,则用该特殊疑问词来引导宾语从句。例如: Could you tell me ? Where is the nearest post office ? (合并句子),Could you tell me Where the nearest post office is ?,注意:连接词作定语时,和它所修饰的词是不可以分开的。例如:What time ,
4、 which room , how many people等。例如: I dont know how many people there are in the room.,要点二:宾语从句的语序,宾语从句一律用陈述句语序。不论从句由哪个引导词引导,也不论主句是陈述句还是疑问句,从句的结构均为“引导词+主语+谓语+其他成分”。(任何动词不得超越到主语之前去。),例:1.We dont know when they will arrive.2.Could you tell me which way we must take to get to the museum?,要点三:宾语从句的时态(有三条
5、规则),1.如果主句是祈使句或是一般现在时或一般将来时态,宾语从句可根据句意选择任何一种时态。例如:,1).Do you know who he was talking with at eight last night? 2). Please tell me how many pictures they have drawn . 3).Mary says she will come back soon .,2.如果主句是一般过去时,则宾语从句常用表示过去的任意时态。例如:,1).He said that he was a cleaner .2).I knew she had cleaned t
6、he house already .,3.如果宾语从句表达的是客观事实、真理、自然现象、名言、谚语等时,主句即使使用了过去时,宾语从句仍然用一般现在时。 例如:,1).He said (that) time is money. 2). Our teacher told us that light travels much faster than sound . 3). She said that one and one makes two .,1.The headmaster hopes everything _ well. (go) 2.Tom says that they _ (play)

9、will come; comes C.comes; will come D.will come; will come,B,解析:例1中包含有宾语从句和条件状语从句,前一句为宾语从句,后一句为时间状语从句。在宾语从句中,当主句为一般现在时,从句可根据句意采用任何时态,故第一空应填将来时;第二句是一个由when引导的时间状语从句,主句为将来时态,从句应该用一般现在时态,故答案为B。,例2.I dont know _ he will come tomorrw. _ he comes, Ill tell you. (2005江苏) A.if; Whether B.whether; Whether C.
10、if; That D.if; If,解析:例中,前一句是宾语从句,用if和whether均可,但后一句为条件状语从句,只能用if,故答案为D。,D,例3. I dont know if he _. He will come if it _. (2004安徽) A.comes; wont rain B.will come; doesnt rain C.comes; doesnt rain D.will come; wont rain,解析:例中,前一句是if引导的宾语从句,根据意思判断应为将来时,后一句是条件状语从句,主句为将来时,从句用一般现在时,故答案为B.,B,在中考试题中,对宾语从句的考
11、查主要体现在三个方面:连词、语序和时态。近年来对状语从句和宾语从句的混合考查更加频繁,要注意综合分析。下面还有五道模拟中考题,大家做做看。,1.I want to know if they_ the spring sports meeting next month.
