(3)与过去进行时连用的时间状语常见的有at nine last night/at that time/at this time yesterday或有when the teacher came in/while he wasreading等的提示。
eg：When the teacher came in，they were listening to music.

eg：When the teacher came in，the students were talking.
当老师进来的时候，学生们正在说话。
When she arrives，I’ll call you.
她一到我就给你打电话。
(2)while表示“当……的时候”，仅指一段时间。while引导的时间状语从句中的动词必须是延续性的，一般强调主从句的动作同时发生。while还可以作并列连词，意为“而；却”，表示对比关系。
eg：Lisa was singing while her mother was playing the piano.
当妈妈在弹钢琴的时候，Lisa在唱歌。
Tom is strong while his younger brother is weak.Tom很壮，而他弟弟身体很弱。
语法点三　初中阶段必须掌握的状语从句
(1)时间状语从句
①时间状语从句常用when，while，as，before，after，since，till，until，as soon as等来引导。
eg：It was raining hard when I got to school yesterday.
昨天当我到达学校的时候，雨下得正大。
While he was doing his homework，the telephone rang.

他来中国之前已经学习了一点中文。
After he graduated from college，he went to work in a factory.
他大学毕业后就去了一家工厂工作。
②在时间状语从句中，通常不用将来时，而用现在时表示将来的动作或状态。
eg：I’ll ring you up as soon as I get to New York.我一到纽约就会给你打电话。
I will tell him everything when he comes back.当他回来后，我会告诉他一切。
He won’t believe it until he sees it with his own eyes.
直到他亲眼看到，他才会相信这件事。
(2)条件状语从句
①条件状语从句通常由if，unless，as long as引导。
eg：What shall we do if it snows tomorrow？
如果明天下雪，我们该怎么办？
Don’t leave the building unless I tell you to.除非我通知你，否则你不能离开这座楼。
②在条件状语从句中，谓语动词通常用现在时表示将来的动作或状态。
eg：I’ll help you with your English if I am free tomorrow.
如果我明天有空，我将帮助你学英语。
He won’t be late unless he is ill.
除非他生病，否则他不会迟到。
③“祈使句＋and/or＋陈述句”在意思上相当于一个带有条件状语从句的复合句。
eg：Study hard，and you will pass the exam.＝
If you study hard，you will pass the exam.努力学习，你就会通过考试。
Hurry up，or you’ll be late.＝If you don’t hurry up，you’ll be late.
快点儿，否则你会迟到。
(3)原因状语从句
①原因状语从句通常由because，as，since等引导。
eg：He didn’t come to school because he was ill.他没来学校，因为他病了。
As it is raining，we shall not go to the zoo.
因为正在下雨，我们将不去动物园。
Since you can’t answer the question，I’ll ask someone else.
既然你不会回答这个问题，我将问其他人。
②because表示直接原因，语气最强。because引导的原因状语从句多放在主句之后。回答由why提出的问题，通常用because。as和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从句多放在句首。
eg：—Why didn’t you go there？
你为什么没去那里？
—Because I didn’t want to.
因为我不想去。
As he has no car，he can’t get there easily.
因为他没车，所以他到那儿不是很容易。
Since we have no money，we can’t buy it.
因为我们没钱，所以我们不能买它。
③because和so不能出现在同一个句子中。

so that等引导。

eg：The hall is so big that it can hold 2，000 people.大厅很大，能容纳2000人。
Amy lives so far away that we hardly ever see her.

◆如果名词前有many，much，little，few等词修饰时，只能用so，不能用such。
eg：Soon there were so many deer that they ate up all the wild roses.

不久，这里有太多的鹿以至于吃光了所有的野玫瑰。
He has so little time that he can’t go to the cinema with you.

eg：We started early so that we could catch the first train.
我们很早出发以便能赶上第一班火车。
We used the computer in order that we could save time.
我们使用电脑的目的是节省时间。
②so that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：a.目的状语从句里往往带有情态动词can，could，may，might等。b.从意思上看，目的状语从句表示的目的往往很明确。
eg：Speak clearly so that they can understand you.讲清楚点儿，以便他们能懂你。
Jack is badly ill so that he has to rest.
Jack病得很严重，所以他必须休息。
