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 going on . Find out the Object Clauses 注：that 在句中无词义，在从句中不能充当句子成分，在口语中往往被省略。 e.g. I hear (that) he will be back in an hour. He told me (that) the meeting was cancelled.（取消） 1，从句原形是陈述句的 由从属连词that引导 二 .宾语从句的引导词 e.g. I hear (that) _____. （一小时后他会回来） He said (that) _____. （他非常想念我们） The teacher told us (that) _____. （地球围着太阳转） he will be back in an hour he missed us very much the earth moves around the sun 2.从句原形是特殊疑问句的 由连接代词 Who,whom,whose,which,what和连接副词 where,how,why,when引导 这些连词既有词义又充当句子成份。 e.g.1)Do you know whose book it is ? （谁的，作定语） 2)Could you tell me why the train is late? （为什么，作状语） 3)He asked who could answer the question. （谁，作主语） 3.从句原形是一般疑问句的 由从属连词 whether, if 引导 e.g. I want to know if/whether she is right . They didn’t know whether Tom could come back or not . if/whether 引导宾语从句 表示“是否”之义，在句中不充当句子成份。 if/whether可互换,但whether…or not为固定搭配. If 与whether 的区别 1.I don’t know _____ he will come or not. 2.That depends on ____ he can come back. 3.He wondered ____ to stay here the next week. 4.__ __ he will come is not decided. 与or not 连用只能用whether 介词后只能用whether 与to do 不定式连用只能用whether 句首只能用whether whether whether whether Whether Helen says that she will learn French next year. Do you know where he comes from? He asked me if I could get to the bus station on time. 三. 宾语从句的语序 无论主句是陈述句还是疑问句，宾语从句都是运用陈述句的语序，即是“主语在前，谓语在后”的顺序。 改一改 将下列问句变成陈述句。 ??? 1. Can he swim ? →??? ?????? ?swim . ??? 2. Does he have a pen ? →??? ??? ????a pen . ??? 3. Which place did he go to ? →Which place ?? ? ? ???. ??? He can He has he went to 说一说 将上面的句子置于一个主句后，变成一个宾语从句。 Can you tell me/I want to know/I wonder/Please tell me……? e.g. Can you tell me if/whether he can swim? 四.宾语从句中时态的变化 填一填 was is will cook is singing has been was playing had learned 1.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需要使用任何一种时态。 （需要性原则） 2.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。（呼应性原则） 1) He will go to Hong Kong . 2) He is sick. 3) He is reading a book . 4) He has finished his work. 1) He to ... ...
