连词when与while的用法when引导的从句中,谓语动词可用瞬间性动词,也可用延续性动词;而while引导的从句中,后面通常用延续性动词。因此在由while引导的状语从句中,谓语动词常用进行时态。如:When

I

came

home,

my

mother

was

cooking

dinner.

当我到家时,我妈妈正在做晚饭。While

/

When

I

was

watching

TV,

he

came

in.

当我正在看电视时,他进来了。3.

一般过去时与过去进行时的用法比较(1)过去进行时强调动作在过去某一时刻或某一段时间正在进行,而一般过去时表示过去某个时间发生过的动作或存在的状态。如:He

was

writing

his

composition

last

night.

他昨晚在写作文。(不一定写完)He

wrote

his

composition

last

night.

他昨晚写了作文。(已经写完)(2)表示过去的状态、感觉及心理活动的动词(如be,like,love,hate,fear,own,hear,see,know,want,notice)可用于一般过去时,但通常不用于进行时。如:I

hated

it

when

a

man

spoke

with

his

mouth

full

of

food.

我讨厌人说话时嘴里含着食物。(3)一般过去时与always,constantly,forever,continually等词连用时,表示过去经常性、习惯性的动作;而过去进行时与always,constantly,forever,continually等词连用时,表示动作的重复,常带有感情色彩。如:He

always

got

up

at

six.

他过去总是6点起床。He

is

always

complaining

about

the

house.

他总是抱怨这间房子。
