结构:主语+谓语+引导词+简单句(其它)
无论主句是陈述句还是疑问句,宾语从句都必须使用陈述语序,可分为以下四种:
1)连接词+谓语。连接词在从句中作主语。常见的连接词有: who,what,which等。如:
Could you tell me who knows the answer,please?The small children don't know what is in their don't know which belongs to my father.
2)连接词+名词+谓语。连接词在从句中作主语的定语。常见的连接词有:whose,what,which,how many,how much等。如:He asked whose handwriting was the best in our teacher asked us how many people there were in the room.
3)连接词+主语+谓语。连接词在从句中作宾语、状语或表语。常见的连接词有:who(m),what,which,how many,how much, when,why,how,where,if /whether(在句中不充当任何成分)。如:He hasn't decided if he'll go on a trip to you tell me what I should do with the money ?
4)连接词+名词+主语+谓语。连接词在从句中作宾语或表语的定语。常见的连接词有:what,which,how many,how much,how等。如:Do you know which class he is in ?
he asked me if I knew whose pen it was.
1)当由陈述句充当宾语从句时,用that引导,that无词义,在口语或非正式文体中常省略。如:He said that he could finish his work before supper.
2)当由一般疑问句充当宾语从句时,用if或whether引导,意为“是否”。如:I don't know if /whether he still lives here after so many years.
但在下列情况下只能用whether:
① 在具有选择意义,又有or或or not时,尤其是直接与or not连用时,往往用whether(if…or not也可以使用)。如:Let me know whether /if he e or not.(=Let me know
whethe or not he e)让我知道他是否能来。 I don't know whether /if he does any washing or not.(=I don't know whether or not he does any washing.)我不知道他洗不洗衣服。I wonder wheth
