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
bedridden纸牌屋第四季字幕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 hou, 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 houwork, 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 wi
一般将来时讲解nter，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.
