12月英语四级考试练习题及参考答案

一、选择题

1.词汇选择题

Whatapity!Consideringhisabilityandexperience,he______better.

A.needhavedone

B.musthavedone

C.canhavedone

D.mighthavedone

答案：D

解析：“mighthavedone”表示对过去事情的推测，意为“也许已经做了某事”，这里说考虑到他的能力和经验，他本可能做得更好，符合语境。“needhavedone”通常用于否定句和疑问句，表示“本不必做某事却做了”；“musthavedone”表示对过去事情肯定的推测，意为“一定做了某事”；“canhavedone”一般用于否定句和疑问句，故答案选D。

Theoldcouplehavebeenmarriedfor40yearsandneveronce______witheachother.

A.theyhadquarreled

B.theyhavequarreled

C.havetheyquarreled

D.hadtheyquarreled

答案：C

解析：当否定词或半否定词（如never,hardly,scarcely等）位于句首时，句子要部分倒装，即将助动词、情态动词等提到主语前面。根据前面的“havebeenmarried”可知，这里用现在完成时，所以答案是C。
