问题补充：
(·高考福建卷)The famous musician，as well as his students， to perform at the opening ceremony of the Taipei Flower Expo.
A. were invited
B. was invited
C. have been invited
D. has been invited
答案：
A. were invited
(答案→)B. was invited
C. have been invited
D. has been invited
解析：选B。题干的意思是：“这位著名的音乐家和他的学生被邀请为台北花卉展的开幕式表演。”“被邀请”是一个发生在过去的动作，而且不表示对现在造成了影响，也不表示动作持续到现在，所以不能选用完成时。根据主谓一致的语法规则，A as well as B作主语时，遵循“就前原则”，也就是说谓语动词要和A保持一致。也可以理解为本句的主语是A而不是B，所以本题谓语动词的数要和the famous musician保持一致，用was invited。
