The Smiths went to the country for the weekend as they ______ to the office.
A.needn’t have goneB.mustn’t go
C.may not goD.didn’t have to go
D

试题分析:此句要表达的意思是:史密斯一家因为不必去办公,所以去了乡下度周末。A中时态与主句搭配错误,B中mustn't表示“禁止”,C项意为“也许不”,与句意不符。  D项正是表达“不必”的意思,所以D项正确。
点评:情态动词有具体的词义,但也同助动词一样,需要与其他词语一起构成句子的谓语,另外情态动词没有人称和数的变化,情态动词后必须跟动词原形。
