教 学 过 程

（包括引新导课、依标导学、异步训练、达标测试、作业设计等）

Step 1: Do some oral English   

Read some words one by one of this unit

Step2:

1．By the time I got outside, the bus had already left.当我出去时，公交车已经开走了。

本句使用的是过去完成时（Past perfect Tense），下面讲一讲过去万城市的用法。

构成：had＋过去分词（had没有人称和数的变化）

过去完成时可以表示过去某一时刻或某一动作之前完成的动作或呈现的状态。也就是说发生在“过去的过去”。既然过去完成时的动作发生在过去某一时间之前，那么，使用过去完成时就必须先有这样一个过去的时间。

eg．I had finished my homework before supper．

    我在晚饭前把作业做完了。

句中的supper既是过去某一时间，而had finished 这一动作就是在supper 之前完成的。如果只说I had finished my homework．听者会觉得难以理解。由此可见，过去完成时是个相对的时态，它不能离开过去的时间而独立存在。

eg．By the end of that year Henry had collected more than one thousand foreign stamps．

    到那年年底，亨利已经收集了一千多张外国邮票。（过去时间是the end of that year）

eg．When we got there, the football match had already started．

    当我们到那里时，足球比赛已经开始了。（过去时间是when从句）

动词过去分词的构成与一般过去式的构成相似，一般情况下在动词词尾加－ed，特殊动词须特殊记忆，如：have—had—had，get—got—gotten，begin—began—begun，leave—left—left，go—went—gone等。例如：

She had learnt 2000 English words by the end of last month．

到上个月末，她已经学了2000个英语单词了。

I hadn't learnt Japanese before I went to Japan．

我去日本之前没学过日语。

注意：过去完成时的否定句和疑问句直接通过had的变化即可。

2.  When I got to school, I realized I had left my backpack at home.我到学校时才发现把书包落在家了。

when当……时候，指过去的某一时间点。从句用一般现在时，主句为过去完成时。had left my backpack at home 这是一个过去完成时的句子，表示在过去某一时间或某一动作之前完成的动作或存在的状态。[来源:学*科*网]

By three o’clock yesterday afternoon we had finished the work.

到昨天下午三点，我们已经完成了工作。

She had learned a lot of English before she went to school.

在上学之前，她已经学会了很多英语。

3.  My alarm clock didn’t go off, and by the time I woke up, my father had already gone into the bathroom and I had to wait for him to come out. 我的闹钟坏了，因此等我醒来的时候，我父亲已经进去洗澡了，我只好等他出来。

by the time I woke up 中的by the time意为“到……的时候”， 指从过去某一点到，从句所示的时间为止，这一时间段。和过去完成时连用。例如：

By the time he was ten, Tom built a chemistry lab himself.

等到了十岁的时候，汤姆自己建了一个化学实验室。
