问题补充：
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：考查主谓一致和时态。当主语由as well as连接的时候，谓语和前面的主语一致，这句话和The famous musician一致，谓语用单数，又因为是的台北花卉博览会，所以用一般过去时，句意：著名的音乐家和他的学生一起被邀请参加了台北花卉博览会故。选B。
【考点定位】考查主谓一致和时态
