After从句:
After he (had) finished his work, he went home.(过去完成时可省略)
3. 用于宾语从句中(主句为一般过去时)
He said (that) he had never been to Beijing.
I thought I had seen her somewhere before.
4. 用于“希望/打算做但未做成”的表达
I had hoped to see you, but I was too busy.

47.A
【解析】句意:当我们赶到会议室的时候会议已经开始了。本句中会议开始的动作发生在我们到达会议室之前,所以表示过去的过去,用过去完成时,故选A
【点评】动词的时态是学习英语过程中非常重要的知识。而很多的题目,句中并没有像本题一样有明确的时间,很多要通过上下文的判断得知。过去完成时表示动作发生在过去的过去,本题不难,平时加强记忆,理解即可。
48.D
【解析】句意: 在那之前,他的家人已经有六个月没有他的消息了。 A.一般过去时;B.过去完成进行时;C.现在完成时;D.过去完成时。根据 Until then 和 for six months 可知,此句用过去完成时,结构为"had done"。故选D。
【点评】考查时态辨析,注意过去完成时的用法。
49.B
【解析】句意:苏上星期没和我们一起去看电影,因为她和她妈妈一起看过了。A.已经看了,现在完成时;B.已经看了,过去完成时;C.将看,一般将来时;D.看了,一般过去时。Sue和妈妈看了电影的影响是上周Sue没有和我们看电影,所以用完成时,根据didn't可知是与过去有关,所以用过去完成时,结构是had+动词过去分词,see的过去分词是seen,故选B。
【点评】考查过去完成时,注意平时识记其结构,理解句意。
50.C
【解析】题中“I got there”表现的是过去时,且题意表达已经开始故为过去完成时,故选C.
【点评】此题考查过去完成时。
