【学习目标】
1. 能够熟记并正确使用下列单词和短语:have a look icy kid realize。
2. 继续学习如何正确使用过去进行时。
3. 能够理解并正确使用when 和while两个词。
4. 能够利用when和while描述自己的日常生活。
1. 以when和while引导的时间状语从句
1) 延续性动词和非延续性动词
延续性动词指动作可以延续一段时间, 而不是
瞬间结束。
如: work、study、drink、eat等。
非延续性动词指动作极为短暂,瞬间结束。
如: start、begin、hit、jump、knock等。
2) 在本单元中, 出现了以when和while引导的
时间状语从句。
when表示“当……的时候”。从句中既可用延续性
动词, 又可用非延续性动词, 这些动词既可以
表示动作, 又可表示状态。从句中的动作既可
和主句的动作同时发生, 又可在主句的动作之前
或之后发生。如:
Mary was having dinner when I saw her .
The boy was still sleeping when his mother got
home yesterday morning .
while表示“在……的时候”、“在……期间”。
它强调主句的动作与从句的动作同时发生或
主句的动作发生在从句的动作过程中。While
从句中必须是表示动作或状态的延续性动词。如:
The weather was fine while we were in Beijing .
She called while I was out.
如果主句的动作在从句的动作过程中发生,
从句常用进行时。如:
While we were swimming someone stole our clothes .
Don’t talk so loud while others are working.
总结
1) when可指时间点, 又可指时间段, 从句中
可用延续性动词, 也可用非延续性动词。
2) while总是指一个时间段, 从句中必须用延
续性动词。
4. ― When ______ the car ______?

6. — Dick gave me a note while I ______ in the

2. 过去进行时
1. 概念: 表示过去某一时刻或某段时间内正进行的动作。
2. 构成: was/were + 动词现在分词
3. 用法:
a: 表示某一时刻正进行的行为, 与特定的过去时间状
语连用,常见的时间有: at 8 last night, at this time
at that time, at that moment 等
e.g. What were you doing at 10 yesterday morning?
I was writing a letter to my father at that moment.
3.现在分词的构成
4.使用进行时态的注意事项
1)一些动词, 如see、hear、love、like、know、
remember; understand、have等表示感情、
知觉和状态的词, 一般不用于进行时态。
2) 在there和here引起的句子中, 常用一般现在
时代替现在进行时。
e.g. Here comes the bus.
There goes the bell.
5. 过去进行时和一般过去时的区别
1) 过去进行时表示过去正在进行的动作,
而一般过去时则表示一个完整的动作。如:
They were writing letters to their friends last night.
昨晚他们在写信给他们的朋友。
(没有说明信是否写完)
They wrote letters to their friends last night .
他们昨晚写了信给他们的朋友。
(表达了他们已写好的意思, 整个写的过程已完成)
2) 当动作延续较长时间时或表示厌烦、赞美等
感情色彩时, 常用过去进行时表示。如:
He was thinking more of others than of himself.
他考虑别人的比考虑自己的多。
(表示说话者赞扬的口气)
The boy was always making trouble then .
那时, 他总是惹麻烦。(表示说话者厌烦的口气)
