问题补充：

A. is going to
B. are going to
C. was going to
D. were going to
答案：
(答案→)A. is going to
B. are going to
C. was going to
D. were going to
解析：用连词and连接的两个并列主语，其谓语要用复数，但是若主语后跟有with，like，but，except，besides，including，together with，along with，as well as，more than，no less than，rather than等连接的另一个名词，其谓通常要与前面一个主语保持一致；表示按计划或安排将要发生的动作，用现在进行时表将来。
