3、water and that things would get better very soon医生告诉我要多喝水，情况很快就会好转。,2whether/if在做“是否”解时引导宾语从句，常放在动词know，ask，care，wonder，find out等之后。在口语中常用if。whether/if在宾语从句中不作任何成分，但含有“是否”的含义，在句子中不可省略。I dont know whether/if this bike is hers.我不知道这辆自行车是否是她的。Can you tell me whether/if your father joined the Party in 1
4、990?你能告诉我你父亲是不是1990年入党的？,【要点拓展】,whether/if在表示“是否”，引导宾语从句时常可通用。但一下情况只可以用whether。介词后的宾语从句用whether引导。We are talk about whether we can get the chance.我们再讨论我们是否可以得到这个机会。whether引导宾语从句可以与or not连用He doesnt know whether they will plant trees on Saturday or not.他不知道他们周六是否会去植树。Whether引导的宾语从句可以置于句首。Whether they

6、as taken.我要知道他服了哪种药。Please tell me who called me just now.请告诉我刚才谁打电话给我。I dont know whom they are speaking to.我不知道他的在跟谁讲话。,【要点拓展】,连接代词一般指疑问，但what除了指疑问之外，也可指陈述。I dont believe what you said.我不相信你所说的话。,4、由连接副词引导的宾语从句when why where how,He asked me where they were born.他问我他们出生在哪里。He asks how we can help p

8、。）我记得我和爷爷奶奶在乡村住过的日子。,【注意】,1、由连接代词、连接副词引导的宾语从句可以向“疑问词+不定式”结构转化。I dont know how I should do with the gifts.=I dont know how to do with the gifts.我不知道怎么处理礼物。,1.宾语从句的语序在宾语从句中需要运用陈述句语序。He asked me where they were born.他问我他们出生在哪里。Do you remember what you should do next?你记得你接下来应该做什么吗？,宾语从句高频考点,2时态的呼应宾语从句中的
9、谓语动词的时态常受到主句中谓语动词时态的影响。因此，要注意保持主句和从句间时态的一致。,例如：He says that Lily is(will be/was)a doctor.他说莉莉是（将要成为/过去是）医生。Ill tell you what I am doing(did/shall do).我将要告诉你我正在做（过去做/将要做）什么。,（1）当主句是现在的某种时态，从句可用所需要的任何时态。,（2）如果主句是过去的某种时态，宾语从句的时态就比较复杂。,1）从句用一般过去时或过去进行时表示与主句谓语动作同时发生。例如：I thought he was old.我认为他老了。He want
10、ed to know who she was waiting for.他想知道她在等谁。2）从句的谓语动词表示在主句动作之前完成的动作，则用过去完成时。He said that he had finished reading the book.他说他看完了这本书。,3）从句谓语动词表示在主句动作之后发生的动作，则用过去将来时。She said that she was going to buy a new bike next week.她说她下个星期要去买一辆新自行车。I wasnt sure if it would rain.我没有把握确定天是否会下雨。,4）从句表示普通真理时，其谓语动词用
11、一般现在时。例如：The teacher told us the moon travels round the earth.老师告诉我们，月亮绕地球转。,3.从句中的否定转移主句谓语动词是think,believe,expect,guess等，表示“认为，相信，期望，猜想“等意思，主句的主语是第一人称，且时态为一般现在时时，从句的否定一般要转移到主句上。其反意疑问句一般与宾语从句一致。I dont believe she will take part in the English evening.我相信她不会参加英语晚会。I dont think its your fault.我认为这不是你的
12、错。改为反意疑问句 I dont think its your fault,is it?,4 混合宾语从句当宾语从句的引导词是who，which，what，when，where，how，why等时，不按正常语序安排，讲这类引导词置于句首。这时主句中的谓语动词常是think,believe,expect,guessWho do you think Tom will invite to the party?你认为汤姆会邀请谁来参加聚会?,宾语从句应掌握的要点,1在四种类型的宾语从句中必须用陈述句的语序，即主语+谓语动词+其它成分，句末用句号；但主句为疑问句时，句末用问号。2在带有宾语从句的复合句中
13、，要注意主句和从句的时态的呼应。当主句的谓语动词是现在时态时，从句的谓语动词可用任何需要的时态。当主句的谓语动词是过去时态时，从句的谓语动词只能用过去时态范围内的某一种形式。从句表示普遍真理时，即使主句的谓语动词是过去时，从句的谓语动词也须用一般现在时。3.在think,believe等动词引起的宾语从句中，如果否定的是后面的从句，一般要将主句动词改为否定形式，而从句仍然用肯定式。,1.What did Mike say?He said _.A.if you are free the next week B.what colour was itC.the weather is fine D.s
