Answer 1

1 B
句意：现在你不能和我们教师谈话，他们正在参加（全校师生的）晨会。
join的参加是“be one member of”，加入某组织
listen少了一个介词，一定要用作listen to才行
attend 参加某项活动，所以正确

2 B is being repaired 被动语态的进行时
句意：你今天怎么走路来上学啊？你的车呢？
坏了，正在修呢。
3 C
refer to 提及 = mention
前面有whom，这里将介词后置要用refer to或talk to，但talk to的意思是“和谁说话”，而不是提及
句意：你知道他提到的时候说很愚蠢的那个人吗？

4 D
make sure of 或 后面跟从句，作宾语从句 we start ...是个句子，所以用make sure that的结构
句意：请确保我们下午四点出发。
