"Professor Smith, along with his assistants, _____ on the project day and night to meet the deadline.
A. work
B. working
C. is working
D. are working"

Answer 1

"答案C
考查时态及主谓一致题。主语是单数时，尽管后面跟有 but ,except, besides, with ，as well as ，together with， along with，like 等引导的介词短语时 ，谓语动词与前面的主语一致。根据后面的day and night可知，需用现在进行时，故选C。"
