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。

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.
b: 表示过去某段时间内正进行的动作。
e.g. We were building a house last winter.
They were waiting for you yesterday.
否定句和疑问句：
e.g. We were not sleeping at home.
Was he feeling well?
3.现在分词的构成
1) 一般动词在词尾加-ing, 如go--going。
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。
如: get--getting    swim--swimming 
show--showing

4) 以字母y结尾的单词, 直接加ing。
    如carrying、playing、studying。
5) 以字母ie结尾的动词, 变ie为y, 再加ing。
   die → dying             lie →lying
6) 以元音字母加e结尾, 或以e结尾, 且e发音的
动词, 直接加- ing。
    see--seeing            be--being
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)
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：
