Answer 1

1.Carriving;leaving
remember doing 记得做过什么事 （已发生）

2.D.marking
get down to doing 固定搭配，开始认真做……

3.A.invited
过去分词表被动，被邀请
C虽然也是过去分词，但是是过去分词的进行时，强调正在被……，与题意不符

4.首先是句型 it takes time to……所以排除CD
另外 connection 是被制造 用被动语态，选B

Answer 2

1.remember doing是做过的事情。他来过也离开了，不管是记得不记得。这个记得的内容都是做过的事情。
2.get down to doing 着手做某事。
3.省略。unless you are invited to speak , you should remain silent ..
4,make the connection.the connection is to be made.
还不懂问HI 我

Answer 3

没分的啊，唉！
1.D 意思是“记得做过某事，记得没去做过某事”，即“记得去了Party，但记得没离开"
2.D 固定用法，“get down to doing something",用主动形式，人去标记
3.A 完整的是"Unless （you are) invited.....”非谓语中可以省略的
4.B 就像“it take somebody sometime to do something",是被动
