解题思路： 单选
解题过程：
9．This is the first time we______ a film in the cinema together as a family.
A．see B．had seen C．saw D．have seen
This is the first time 的固定时态用法是什么？？
当主句是this is the +序数词+time+从句时，从句里面要固定使用完成时态，当前面是is的时候用现在完成时，如果前面是was的话要用过去完成时。所以这道题目只能用have seen
15．A notice was _____in order to remind the students of the changed lecture time.
A．sent up B．given up C．set up D．put up
这个题目考查短语的意思
sent up 上升，提高，发射
give up 放弃
set up表示建立
put up表示张贴
这里表示张贴通告，所以要选D
16．He must be helping the old man to water the flowers,_______?
A．is he B．isn’t he C．must he D．mustn’t he
当must be在主句充当谓语时，反义疑问句要根据句子的语境和主语来选择用isn't 或者wasn't 或者aren't 或weren't.
这道题目只有isn't而且主语是he，所以应该选B。
很高兴为你解答，有疑问请继续讨论。
最终答案：略
