一、主句和宾语从句的时态关系
1.宾语从句时态的灵活性
当主句谓语动词的时态为一般现在时、现在进行时、现在完成时等时态时,后面宾语从句中的谓语动词时态不受主句时态的限制,可根据具体情况,选用各种合适的时态。(注意:有些词如would或could等不是表示过去,而只是使语气更加委婉客气,其后面跟的宾语从句中的谓语动词的时态不受主句时态的限制,可根据具体情况,选用各种合适的时态。)
例1:-Can you guess ____ the MP4 player yesterday?
-Sorry, I’ve no idea about it.(2007年天津)
A. how much did he pay for B. how can he get
C. how much he paid forD. how he has got
解析:根据宾语从句中的 yesterday可知应用一般过去时态,先排除B和D;又因为宾语从句的语序应用陈述语序,所以选C。
