4a
以when和while引导的时间状语从句
1.
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)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.
3)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.
While the boys were playing football, it rained.
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:
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。
过去进行时
2.
e.g.What were you doing at 10 o’clock 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

9. They ______________ (play) soccer on the field at 3:00 yesterday afternoon.
10. She was drawing a picture when the teacher ________ (come) in.

现在分词的构成
3.
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。
get→getting
swim→swimming
show→showing
4)以字母y结尾的单词，直接加-ing。如：
5)以字母ie结尾的动词，变ie为y，再加-ing。
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。
carrying
playing
studying
die→dying
lie →lying
see→seeing
be→being
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。
使用进行时态的注意事项
