We hope (that)_. （ 他会赢得这场比赛）,he wants to buy a new car.,he will come back tomorrow.,he will win the match.,由从属连词 whether, if 引导的宾语从句注：“Whether”,“ if ”在从句中不充当任何 成分，可译成：“是否”。,1. I want to know _ （他是否跟我们一起去） 2. Ill ask him _.（明天他是否能来） 3. I dont know _. （是否要下雨）,if (whether) he will go with us.,whether (if) he can come tomorrow,Whether(if) it is going to rain.,1.当句中有or not时， or not可紧跟whether后，也可置于句末；若用if引导词法，只能放在句末：* I want to know whether(if) he can come here or not.* I dont know whether or not he will win this time.2.在介词后面,引导词只能用whether而不能用if. * Were talking about whether he can finish the work in time.,whether与if的不同用法：一般情况下， if常用于口语， whether多用于书面语，二者可以互换，但在下列情况下只能用whether。,I cant decide whether to join them.We dont know whether to tell him the news.,3. Whether后可接动词不定式短 语，而if不能.,由连接代词what, who，whom, which, whose 和连接副词 when, where, how, why引导的宾语从句,1.He asked _. (谁能回答这个问题）Do you know_. 他们在做什么？）3. He asked _。 （谁的故事是最好的）4.

Would you tell me _?（为什么火车迟到了?）,how I can get to the park,why the train is late,where he is,地点状语,原因状语,方式状语,特点：在宾语从句中既起引导词的作用，同时在从句中又充当一定的成分。,连接代词 what, who,whom, which,whose连接副词 when, where, how, why,宾语从句的语序 无论主句是陈述句还是疑问句，宾语从句都要运用陈述句的语序，即“主语在前，谓语在后”的顺序。 公式：引导词主语谓语其它,Could you tell me_ _?（我怎样到达动物园）Please tell me_. （他来自哪里）3.Do you know_? （我们什么时候可以回家）4.Please tell me_. （他的学校在哪里）,how I can get to,the zoo,where he comes from,when we can go home,where his school is,3 . 时态的变化 . 当主句是一般现在时时，宾语从句的时态不受 限制，可以根据实际需要来确定具体的时态。 a. I hear ( that ) Jim went to work yesterday. b. He says (that) we are going to visit Beijing next week. c. We all know that he was sleeping at this time yesterday. d. Lets find out who broke the window just now.,当主句是一般过去时的时候，_,he would go to Xian . he was ill yesterday .He said ( that ) he was reading a book . he had supper at home .,宾语从句必须用相应的过去的某一种时态，从而达到主句和从句的相互一致。,当宾语从句说明的是客观事实、自然现象、科学真理等时，从句不受主句限制，用一般现在时态。 a.The teacher told us( that) the earth moves around the sun. b. The teacher told us (that) the man is a worker. c. My father said (that) the sun rises in the east and sets in the west.,根据实际需要选择相应的任何时态,相应的过去时态,从句不受主句的限制，仍用一般现在时,宾语从句应用过程中需注意的两个问题：,标点符号问题;用so代替一个宾语从句的情况。,标点符号 宾语从句末尾的标点符号由主句决定，不受从句的限制。如果主句是陈述句或者是祈使句时用句号；而主句是疑问句时，句末则用问号。 1.He asked me if / whether I could help him . 2.Please tell me which color you like best . 3.Do you know where Li Ping is ? 4.Could you tell me how I can get to the shop? 5.
