3、e maths at all.归纳：由that引导的陈述句，由于that没有任何意义，也不充当任何句子成份，可以 。如果由and连接两个 的宾语从句时，第二个that则不能 。2观察：.Can you tell me what theyre looking for?I dont know where she has gone. 归纳:由连接代词或连接副词who, whose, what, which, when , where, how , why 引导，含有“ ”等特殊疑问意义。3由从属连词whether和if引导，含有“是否，能否，对否，有否”等一般疑问意义。常用在ask，care，fin

4、d out，know， wonder等动词后引出带有疑问意义的宾语从句。在这类宾语从句中要注意两点：（1）if引导宾语从句和状语从句的区别观察： I dont know if the letter is yours.Theyll go boating if it is fine tomorrow. 归纳：Aif引导宾语从句时意为“ ”，从句中该用什么时态就应用什么时态。Bif引导状语从句时意为“ ”，从句中应用一般将来时，即主将从现。（2）whether与if引导宾语从句时，一般可通用，但下列情况下whether不可换用if。观察：1.I dont know whether or not it

7、e earth.归纳：（1）观察句1、2，当主句的谓语动词 时态时，宾语从句的谓语动词可以和主句的谓语动词时态不一致，就是说可根据实际需要用不同的时态。（2）观察句3、4，当主句中的谓语动词是 时态时，宾语从句的谓语动词要用和过去相关的时态，可以是一般过去时、过去进行时、过去将来时和过去完成时等。（3）观察句5、6，在“Could you tell us？”这种表示请求的疑问句中，用could比can 较为委婉客气一些，但could不表示过去时，所以宾语从句中的谓语动词时态可根据需要用 ( 不同 / 相同 ) 的时态。 （4）观察句7，如果宾语从句所叙述的是客观真理时，其谓语动词则用 时态。(

8、三)、从句部分的语序观察：Do you know where Mary lives?
