问题补充：
--- Have you heard that Jenny, along with her classmates, to Harbin for the winter vacation?
--- Really? No wonder I haven’t seen her these days.
A. had gone
B. have been
C. has gone
D. have gone
答案：
A. had gone
B. have been
(答案→)C. has gone
D. have gone
解析：考查时态和主谓一致：句意：你听说Jenny和她同学去哈尔滨过寒假了吗？--真的吗？难怪我最近没看见她。可知Jenny和她同学是已经去了哈尔滨，用have/has gone, have/has been,是曾去过，不符合句意，还有主语是along with连接的时候，谓语和前面的主语一致，就是Jenny，谓语是单数。选C。
