-----He should have come to join in the thorough cleaning. -----He________, I think. It’s not his turn.A.needn’t have to | B.needn’t have | C.didn’t have to | D.doesn’t need to |
|
答案
C |
解析
考查have to用法。have to表示客观需要做的事情,意思是“必须”、“不得不”。后跟动词原形,有人称、时态和数的变化,其否定形式是在前面加助动词与not。与情态动词 must 近义,但他不是情态动词。句意:他应该来参加大扫除的。——我认为他不必来。今天不是他值日。结合语境可知下文描述的是过去的动作,故助动词用过去时态。选C。 |
