问题补充:
Not only the students but also the teacher enjoying the film at 9 pm yesterday.
A. has been
B. was
C. are
D. is
答案:
A. has been
(答案→)B. was
C. are
D. is
解析:昨天上午九点,不但学生们,老师也很喜欢这部电影。结合语境可知本句描述的是过去某时正在进行的动作,故用过去进行时态。当由not only but also连接两个主语时,谓语动词与最近的主语保持一致,the teacher是单数第三人称,故助动词用is的过去时态was,选B。
