B引导词 1如果是陈述句作宾语从句，用that引导，可以省略， I hope that you’ll have a good trip. I’m surethat she’ll pass the exam. I’m afraid that I can’t come. 2 如果是一般疑问句作宾语从句，要用if或whether引导，（考点注意将疑问顺序改为陈述句形式） Will it rain next day He asked me. He asked me ___________ it would rain the next day. Mr Green doesn’t know __________ his daughter will return tomorrow. 注意介词后只能用whether, We are worried about ___________ the student will joins the swimming club. 注意 if或whether引导的宾语从句。表示“是否”，二者通常可以互换 但 whether和if都可以与or not连用。但if与or not之间常需要用词语隔开，而whether与or not可连用 Can you tell me whether or not the train has leftCan you tell me whether the train has left or not 下列情况，只用whether作引导词 a引导主语从句、同位语从句、表语从句、让步状语从句。例如 Whether he comes or not doesnt concern me.他来不来与我无关。
I am in doubt whether I ought to give this plan my approval..我决定不了是否该同意这项计划。
What I want to know is whether you can help me.我想知道的是你是否能帮助我。
Whether we go or stay, the result is the same.不管我们是走还是留，其结果是一样的。
b）与不定式连用例如 I dont know whether to accept or refuse.我不知道是该接受还是该拒绝。
c）在介词后作介宾。例如 I am not interested in whether you like the plan or not.我不在乎你是否喜欢那项计划 3如果是特殊疑问句作宾语从句，必须用who,whom,whose,what,which,when,where,why,how等引导。
（考点注意将疑问顺序改为陈述句形式） Could you tell me____________ A. when the train would arrive B. When the train will arrive C. when will the train arrive D. when would the train arrive I’m thinking about _______ she said just now. A. how B.what C. when D. where 但注意特殊情况 当疑问代词what，who在特殊疑问句中做主语时，该特殊疑问句本身就是陈述句语序，所以当该句用来做宾语时，语序不需要调整。
He asked the girl what was wrong with her．他问这个女孩怎么回事了。
He asked the girl what was the matter．他问这个女孩怎么了。
We want to know what has happened to him．我们想知道他发生了什么事。
I wonder what’s happening 同类句式还有I want to know who broke the window 谁打破的窗户 I want to know who is in the classroom 谁在教室里 I want to know what made him so angry．什么使得他如此生气。
C宾语从句的时态考点时态的运用 1）若主句谓语是一般现在时，从句根据需要该用什么时态就用什么时态 He says that some boys __________playgames on the grass 10 minutes ago. I’m sure that he ___________pass the math exam. 2 若主句是过去时态，从句用与过去相关的时态。
He wanted to know if I would go there by bus. My teacher asked us who could answer the question. 3 不管主句是什么时态，只要从句所说的是客观事实、真理、自然规律、格言等，从句时态应用一般现在时。
Our geography teacher told us that the earth ___________goaround the sun. The physics teacher said that light travels much faster than sound. D宾语从句的特殊情况 1） 是否转移think / believe / suppose / expect 在这样的句型中 I/We thinkbelieve/guess/ 宾语从句， 如果从句要否定，应该将其否定转移到主句上。
I think he can sing this English song.否定 I _________think he _______ sing this English song. 2 反意疑问 ①一般情况下，根据主句主语和谓语进行反意疑问 Bill wanted to know who did this, _________ ___________ ②对于否定要转移的从句，即I/We thinkbelieve/guess/ 宾语从句,反义疑问句要根据从句反意疑问 I don’t think English is easy, ______ _________ We think the boys could write something in English, ________ __________ 另外，当think ，suppose，believe，imaging，guess这类表示“认为”、“猜想”的动词作主句谓语时，常会出现一种以疑问词起头的双重疑问句插入语do you think。
What do you think he is 你认为他是做什么的 How much time do you suppose I must spend on it 你认为我得花多少时间来做这件事 中考在线 语法专练A.句型 1.“Don’t sleep in class,” the teacher told us.
