3 Find out the Object Clauses
Do you know who is the first Chinese astronaut(宇航员)? Our teacher told us that the earth goes around the sun. Please tell me where she has gone. I don’t know if he will come tonight. Let’s find out what’s on tonight .

4 1.由从属连词that引导的宾语从句 e.g. 1.I hear (that) he will be back in an hour. 2.He said (that) he missed us very much. 注：that 在句中无词汇意义，在从句中不能充当成分，在口语当中往往省略。

5 2.由从属连词 whether, if 引导的宾语从句
if/whether 引导宾语从句 表示“是否” if/whether可互换, 但whether…or not为固定搭配. I want to know if/whether she is right . They didn’t know whether Tom could come back or not .

6 3.由连接代词 Who, whom, whose, which, what 和连接副词 where, how, why, when引导的宾语从句
e.g. 1.Do you know whose book it is ? 2.Please tell me when we’ll have a meeting . 3.Could you tell me why the train is late? 4.He asked who could answer the question.

7 当主句是一般现在时，宾语从句的时态不作限制，我们可以根据句子的意思来使用需要的任何一种时态。
I hear (that) Jim went to work an hour ago. he is interested in English. she will come tomorrow . Tom has been to London twice .

8 当主句是一般过去时的时候，宾语从句必须运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。
He will go to Hong Kong . He is sick. He is reading a book . He has finished his work. He would go to Hong Kong . He said He was sick. He was reading a book . He had finished his work.

9 当宾语从句说明的是客观存在的事实或者是客观存在的真理时，就不用受到主句时态的限制，仍是用一般现在时态。
He told me (that) Summer is after Spring . We kmew (that) the sun is much bigger than the moon . The teacher told us (that) the earth moves around the sun.

10 主句时态 从句时态 一般现在时、一般将来时、祈使句时 根据句意的需要用任意一种时态 一般过去时 与原句相对应的过去的时态 客观事实、真理、自然现象、名言警句、谚语等 一律用一般现在时

11 无论主句是陈述句还是疑问句，宾语从句都是运用陈述句的语序，即是“主语在前，谓语在后”的顺序。
Danny says that he will learn English. Do you know where he came from? Please tell me how I can get to the bus station .

12 宾语从句三要素 时态 that+陈述句 引导词 if／whether+一般疑问句 特殊疑问词+特殊疑问句 语序
主句为一般现在时从句可为任何时态 时态 主句为一般过去时 从句 一般过去时 过去将来时 过去进行时 过去完成时 客观真理时态不变 语序 宾语从句的语序都为陈述句语序

13 He wondered who bought the pen.
1. Tom said. He is reading a book. → 2. He asks me. Are they playing a game? 3. Where is the hospital? He told me. 4.Who bought the pen? He wondered. Tom said that he was reading a book. He asks me if/whether they are playing a game. He told me Where the Hospital was. He wondered who bought the pen.

14 宾语从句歌 学习宾从三注意，时态语序和连词。 时态主从要呼应： 主句若为现在时，从句时态随句意； 主句若为过去时，从句时态变过去；
宾从若是表真理，时态不变无质疑。 语序要用陈述序，切莫照搬疑问句。 That 连接陈述句，省与不省要注意。 从句若表“是否”时，if/whether要慎记。 特殊问句作宾语，仍用原来疑问词。 三个问题需牢记，切莫丢东忘了西。
