(2).By the time the teacher came in,I had drawn a picture. 4: 過去完成時的用法 1、過去完成時表示在過去某一時間或動作之前已經(jīng)發(fā)生或完成了的動作。它表示動作發(fā)生的時間是“過去的過去”，常

6、用以下幾種方式：(1). 用介詞by,before等構(gòu)成的時間短語.We had learned 20 English songs by the end of last month.They had repaired the machine before midnight. (2). 用連詞when, before, after等引導的時間狀語從句.The plane had taken off when I reached the airport.They had cleaned the room before we arrived. 2、過去完成時還可以表示從過去某一時間開始，持續(xù)到過去另

7、一時間的動作或狀 態(tài)。往往與for ,since引導的表示一段時間的短語或從句連用。（1）.I heard from him last Sunday,I had not heard from him since 2003. (2). He had lived here for ten years before I moved here.*使用過去完成時的判斷依據(jù) 3、由時間狀語來判定一般說來，各種時態(tài)都有特定的時間狀語。與過去完成時連用的時間狀語有:by ,by the time+句子, by the end of ,before+過去的時間點等。如：How many English film

8、s had you seen by the end of last month?We had planted three hundred trees before last month. 4、由“過去的過去”來判定. 過去完成時表示“過去的過去”, 動作是先后關(guān)系。 這種用法常出現(xiàn)在賓語從句或狀語從句中。 1）主句謂語為一般過去時（said, asked, told, thought）,賓語從句常要用過去完成時。如：He asked what had happened to me.She told me that she had seen the film.在 when,before 等引導的

9、時間狀語從句中，如果時間狀語從句的動作發(fā)生在主句之后，從句用一般過去時，主句要用過去完成時。如：When I got to the bus stop , the bus had gone.He had already finished his homework before his mother returned.3）表示從過去某一時間開始，持續(xù)到過去某一時間的動作或狀態(tài)。常與for/since引導的表示一段時間的短語或since 引導的從句連用。這種用法如同現(xiàn)在完成時，謂語動詞只能用be,live,study,work 等表示延續(xù)性的動詞，而不是用表示非延續(xù)性的動詞（come, begin,

10、 leave, buy等）。如：誤：When we got to the theatre, the play had begun for ten minutes.正：When we got to the theatre, the play had been on for ten minutes.三: 達標驗收(10分鐘) 1. 用括號內(nèi)所給的動詞的正確時態(tài)填空.1).He told me that he_(write) a new book.2).The pen I_(think) I had lost is in my desk.3).He came here as soos as he _
