宾语从句ppt.ppt

1、宾语从句复习三要点,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 tell us if

2、/ 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5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 is true or

3、 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.,5）.用在discuss后面时：,They are discussing whether they should go by bus.,小结：三前二后: 句子前面，or not前面，不定式前；介词之后与 discuss后，要用whether不用if.,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 neare

4、st 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 , 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”。,例如：1.We dont know w

5、hen 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

6、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 the 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 th

9、考的宾语从句试题,请看这三道中考试题: 例1.I dont know when he _ . When he _ ,Ill let you know. A.comes; comes B.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 _

10、 he will come tomorrw. _ he comes, Ill tell you. (2005江苏) A.if; Whether B.whether; Whether C.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 _.

11、n,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.
