In order to meet the deadline, Professor Smith along with his assistants       the project day and night.

A.work on

B.works at

C.is working on

D.are working on

答案

C

题目分析:考查词组和主谓一致。A. work on从事,忙于,B. works at致力于,因为主语由along with,连接时,其谓语动词的单复数形式通常由前面的词来决定。就是Professor Smith故用单数谓语,在BC里面选择,句意:为了如期完成,斯密斯教授和他的助手日夜忙着这个项目。答案为C项。

点评:主语由as well as, along with, together with, rather than, no less than, but, except, besides, in addition to, like, including等词连接时,其谓语动词的单复数形式通常由前面的词来决定。这题还考查了work相关的短语,做题目要综合考虑。
