初三宾语从句教案②在介词前：It depends on(依靠) whether it is going to rain.③与or not连用：They are talking about whether to go there or not.④做主语：whether he will come is not decided.3、连接代词who, whom, whose, what, which，连接副词when, where, why, how，它们起连接作用，作句子成分，各有自己的意义。
eg. The teacher asked the new students which class he was in.I wonder where he got so much money.He asked who could answer the question.Do you know whom they are waiting for.Please tell me when we will have a meetingCould you tell me how i can get to the bus stationWould you tell me why the train is late【注意】由连接代、副词引导的宾语从句可以和“疑问词+不定式”结构转化。
eg. I don’t know h ow I should do with the presents. I don’t know how to do with the presents.练习：Can you tell me how i can get to the station?（二）语序宾语从句的语序都用陈述句语序，即“连接词+主语+谓语+其它成分”（正常的主谓语序）eg：Please tell me where i can buy the beautiful flowers.Do you know what the population of China is?注意事项: 当从句的原句为以下句子以及what, who作主语时，语序不变，例如：What’s wrong(with you)? What’s the matter? What’s happening?eg:I don’t know what’s the matter. Can you tell me who is over there?练习：翻译句子完成下列宾语从句：1. Please tell me _______________________. （我们什么时候开会）2. Can you tell me _______________. （他在哪儿）3. Could you tell me ______________________. （我该怎么去车站）4. Would you tell me _________________（为什么火车迟到了）5. I want to know _____________________. （他是否跟我们一起去公园）6. Ask him _____________________. （他是否能来）7. I don't know ___________________________.（是否要下雨答案：1.Please tell me when we are going to have a meeting. （我们什么时候开会） 2. Can you tell me where he is?（他在哪儿）3. Could you tell me the way to the station? （我该怎么去车站） 4. Would you tell me why the train is late?（为什么火车迟到了）5. I want to know whether he will go to the park with us. （他是否跟我们一起去公园）6. Ask him if he can come. （他是否能来）7. I don't know whether it will rain (or not).（是否要下雨）（三）、时态1.如果主句的时态是一般现在时，宾语从句的时态根据具体情况来确定，可以是任何时态。
I don’t think (that) you are right.Please tell us where we will go fishing tomorrow.Do you know when Mr. Smith moved here?2. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态（一般过去时，过去进行时，过去将来时，过去完成时）。
Eg：He told me that he was born in Beijing in 1992.He said that he would go back to the U.S.soon.特殊情况：1.从句说明的是客观真理、客观事实、自然现象、名言时，仍用一般现在时。
Dad told us that it is better to do than to say.He told the boy that three and three is six.Could you tell me where the bookshop is.2.从句中有具体时间状语，即使从句动作发生在主句动作前，仍然用一般过去时。
The teacher told me she was born in 1960.2.[即学即练]子连接成为含有宾语从句的复合句。
1. These flowers are from Guangdong. He said.He said _______ these flowers _______ from Guangdong.2. Light travels faster than sound. My teacher told me.My teacher told me _____ light _______ faster than sound.3. There will be a meeting in five days. Jack didn’t know.Jack did not know ______ there ______ ____ a meeting in five days.4. Can they speak French? I want to know.I want to know ______ _______ _______ _______ French.5. Are the children playing games? Tell me.Tell me ______ the children ______ ______ games.6. Have you finished your homework yet? Mr. Zhao asked Ma ChaoMr. Zhao asked Ma Chao _______ _______ ______ _____ _____ homework yet.7. How many people can you see in the picture? Who knows?Who knows _____ _____ ____ ____ _____ ______ in the picture?8. Where did she park her car? Do you know?Do you know _____ _____ ____ her car?三、其他需要说明的问题：a.从句的主语如果是第一人称，变为宾语从句则与主句的主语一致；如果是第二人称，则与主句的宾语一致；如果是第三人称，不用变化。
如：(一主二宾三不变) “May I use your knife？”He asked me. →He asked me if he might use my knife.“Do you know her telephone number？”He asked me. →He asked me if I know her telepho ne number.b. 宾语从句的标点均由主句决定。
主句是陈述句，用句号；主句是疑问句，用问号。
如：Who will give us a talk? I don’t know. →I don’t know who will give us a talk.Do you know？Where does he live? →Do you know where he lives?四、宾语从句和状语从句的区分：eg. 1) I will go out tomorrow if it is fine.2) I don’t know if the train has arrived.句1中if引导的是状语从句。
这个从句表示“条件”，修饰主句。
整个句子的意思是如果明天天气好，我就出去。
句2中if引导的是宾语从句，充当谓语动词don’t know 的宾语。
整个句子的意思是我不知道火车是否到达。
判断方法：1、可以从整个句式看。
状语从句一般可以放在主句的前面或后面（个别除外），宾语从句只能放在主句谓语动词之后。
2、从引导词看。
if充当宾语从句的连接词时，相当于whether，词义为“是否”，充当状语从句的连接词时，词义为“如果”。
when充当宾语从句的连接词时，意为“什么时候”，充当状语从句的连接词时，意为“当……的时候”。
3、从时态看。
if和when作连接词时，引导宾语从句要注意：从句的谓语动词的时态应根据主句的时态作相应的变化。
if和when充当从属连词时，引导条件和时间状语从句，若主句的谓语动词用一般将来时，则从句的时态应用一般现在时表示将来。
练习：1. She asked me if I knew _______.A. whose pen is itB. whose pen it wasC. whose pen it isD. whose pen was it2. I don't know _______ he still lives here after so many years.A. WhetherB. whereC. whatD. when3. I don't know ______ he will come tomorrow. _______ he comes, I'll tell you.A. if, whetherB. whether, whetherC. if, ThatD. if, If4. The small children don't know ________.A. what is their stockings inB. where is in their stockingsC. where is their stocking inD. what in their stockings五、宾语从句的转化1.当主句谓语动词是hope，wish，decide，forget，plan，agree等，且主句主语与从句主语相同时，从句可简化为不定式结构。
