等他到学校的时候，第一节课已经上完了。

　　How many buildings had been destroyed when the hurricane ended?

　　飓风结束的时候，有多少座大楼被毁坏了？

　　(2) 在told, said, knew, heard, thought, found等动词后的宾语从句中，表示宾语从句中的动作已被做完时，要用过去完成时的被动语态。

　　He heard that the tickets had already been sold out.

　　他听说票已售完。

　　The newspaper reported more than 1，000 people had been killed in the hurricane.

　　报纸报道说有一千多人在飓风中丧生。

　　(3)在It was the first/second ...time that ...句型中。此句型主句用一般过去时，that引导的定语从句中的谓语动词用过去完成时。

　　It was the third time that he had been beaten black and blue.

　　那是他第三次被打得青一块紫一块的。

　　二、直接引语和间接引语

　　直接引述别人的原话，叫作直接引语；用自己的话转述别人的话叫作间接引语。直接引语如改为间接引语，必须在语序、人称、时态和状语方面做相应变化。

　　1．直接引语是陈述句，变为间接引语时由连词that引导。

　　Mary said to her friends，"I don't like computers."

　　　　　　　　　 　　　　↓　　↓

　　→Mary said to her friends that she didn't like computers.

　　2．直接引语是一般疑问句，变为间接引语时变成if/whether引导的宾语从句。

3．直接引语是特殊疑问句，变为间接引语时特殊疑问句变为由who, when, where, why, how等疑问词引导的宾语从句(注意：从句中需是陈述语序)。
