????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

2) 以不发音字母e结尾的动词, 先去掉e, 再加-ing。
come--coming???make--making?? write--writing
3) 以重读闭音节结尾的动词, 如果末尾以一个
辅音字母结尾, 应先双写这个字母, 再加ing，
x和w结尾的除外。

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)过去进行时含义: 表示过去某个时刻
正在进行的动作。
结构：
was/were + doing
例句：
I was having an English
class at this time yesterday. 现在进行时含义: 表示现在
正在进行的动作。
结构：
is/am/are + doing
例句：
I am having an English class. 6. 4a. Look at the table and write sentences

when 既可指某一点时间, 也可以指一段时间;
while 强调一段时间, 所以从句的谓语动词常是延续性的。
当 when表示“在某一段时间里” 的意思时, 它可以代替
while, 但while不能代替when.

当我到家时, 她正在做饭。
When you hang wet clothes near a fire, you will see
steam rising from them.
当你把湿衣服挂在火边时, 你会看到水汽从衣服上升起。单项选择1. I met a friend of mine _____ I was walking in
