Before I repaired my bike, my mother had bought a new one for me. 在我修理我的自行车之前，妈妈已经给我买了一辆新的。 (3)After+从句(过去完成时)，主句(一般过去时). After I had applied for the job, I went to London. 在我申请那份工作之后，我去了伦敦。(4)过去完成时用在主句为过去时的宾语从句中。 They told us they had cleaned all the rooms. 他们告诉我们他们已经打扫了所有的房间。[辨析] 过去完成时与一般过去时 过去完成时表示过去某一时间或动作之前已经发生或完成的动作，即“过去的过去”；而一般过去时表示的是与“现在”相对而言的过去，两者在时间上相差一个时间段。当表示几个动作连续发生时，应用一般过去时态。 By the time I was five, I had started learning English. 到我五岁时，我已经开始学习英语了。 I started learning English at the age of five. 我五岁时开始学习英语。Ⅰ. 单项选择 1. |乌鲁木齐中考|Robert was very upset that most of his friends 　　　when he 　　　 at the party.
