重点语法

过去进行时

过去进行时的构成：be的过去式+现在分词

过去进行时和一般过去时经常同在一个句子里使用。过去

进行时表示过去正在进行的动作或情况，一般过去时则表

示比较短暂的动作或事件。

正在进行中的动作或情况往往由连词when，while，as，just

as

等引导。

when，while 当……时候（强调动作同时发生）

while+从句, 动词一定是延续性动词

when+延续性动词/瞬间动词

while 能用when 代替______，但是when 却不一定能用while 代替。while 通常只引导持续时间较长的动作，

并且主句和从句可以同时用过去进行时，而when 和as一般不这么用。

John was watching TV while his wife was talking with a neighbour over the phone.

Just as I was leaving the house, you came in.

when 也可以引导比较短暂的动作，while和as则一般不行。We were having supper when the lights went out.

过去进行时往往与表示一段时间的状语连用，如all morning，all night，all day，all evening，the whole

week等，表示这段时间一直在干什么。

What were you doing all evening? I cou ldn’t find you anywhere.

过去动作同时发生的时态

①过去两个动作同时发生, 习惯上一个用一般过去时, 另一个用过去进行时；动作长用过去进行时,

动作短用一般过去时; 分工的情况, 动作的开始时间和结束时间几乎相同, 均用过去进行时;

I was listening to the radio, my sister was dancing.

When my mother was doing the housework, my father was watching TV.

②两个动作在同时段进行, 在不同时间结束, 先发生的动作未结束, 另一个动作发生, 先发生的动作

用进行时态, 另一个动作用过去时.

When I was opening the door, the telephone rang.先开门When the telephone was ringing, I opened the door. 电话先响③瞬间动词（如：arrive）没有进行时态, 所以两个动作同时发生, 延续性动词用进行时态, 瞬间动词

使用过去时态.

When he arrived, I was having dinner.

I am arriving 进行时态表示将要

1、The plane was late and detectives were waiting at the airport all morning. 飞机误点了，侦探们在机场等了整整一上午。

all 一般直接加表示时间的单数名词构成副词短语，如：all day，all night，all week，all winter，all year

等。但不说all hour。

whole在表达同样的意思时一般要加冠词或数词，如 a whole day/year，two whole weeks。

all morning=all the morning

The plane was late 飞机晚(点)了

The bus was late./The train was late.
