新概念英语第二册第62课语法知识点 Grammar in use

　　1.过去完成进行时 (The past perfect progressive tense)构成： had been+现在分词

　　(1)过去完成进行时用于强调某动作在过去更早的某一段时间内一直在进行，并对过去某一时刻产生结果。与它经常连用的表示时间的词有before, for, since, all day等：

　　She was very tired. She had been typing letters all day.她很累了。她整天都在打信件。

　　(2)过去完成进行时可用来表示过去经常重复的动作：Jill was angry. Jim had been phoning her every night for a whole week.

　　吉尔生气了。整整一星期，吉姆天天晚上都给她打电话。

　　(3)它还可以表示根据直接或间接的证据而得出结论：Her eyes were red. It was obvious she had been crying.她的眼睛红了。显然她刚哭过。

　　(4)在包含间接引语的句子中，如果引述词是过去时态，则现在完成进行时要改为过去完成进行时(cf.第15课语法)：

　　2.过去完成进行时与过去完成时的比较

　　过去完成时在第14课与第38课的语法中已经学过。它与过去完成进行时有时可以替换使用：

　　Dan had worked/had been working for the firm for fifteen years when I first met him.我第一次遇见丹时，他已在该公司干了15年了。

　　需要表示某个工作已经完成时，只能用过去完成时：

　　When I got home, I found that Jill had been painting her room.我回到家时，看见吉尔在粉刷她的房间。(工作尚未完成)

　　When I got home, I found that Jill had painted her room.我回到家时，发现吉尔已经粉刷过她的房间了。(已完成)

　　When I arrived, they'd already put the fire out.我到达时，他们已经把火扑灭了。(不可用过去完成进行时)
