高二-时间状语从句讲练

时间状语从句-
1.由when, while, as引导的时间状语从句。注意：三者的区别：
when引导的从句的谓语动词可以是延续性的动词， 又可以是瞬时动词。并且when有时表
示“就在那时”。
When she came in, I stopped eating.她进来时，我在吃饭。
While引导的从句的谓语 动作必须是延续性的，并强调主句和从句的动作同时发生（或者
相对应）。并且while有时还可以表 示对比。
While my wife was reading the newspaper, I was watching TV.
I like playing football while you like playing basketball.
As表示“一边……一边 ”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发
生；as也可以强调“一先一后。
We always sing as we walk.我们总是边走边唱。
As we was going out, it began to snow. 当我们出门时，开始下雪了。
注意：从句动作和主句动作同时发生，且从句动作为延续性动词时，when，while，as都
可 使用。
①When ／While ／As we were dancing，a stranger came in．（dance为延续性动词）
当我们跳舞时，一位陌生人走了进来。
②When ／While ／As she was making a phonecall，I was writing a letter．（make为延
续性动词）当她在打电话时，我正在写信。
考点练习（1）：用as when while 填空
1._______ she came in, I stopped eating.
2.________ I lived in the countryside, I used to carry some water for him.
were about to leave ________ he came in.
the iron _______ it is hot.
5.________ my wife was reading the newspaper, I was watching TV.
always sing _______ we walk.
7.________ we were going out, it began to snow.
8._______ time goes on, her hair is getting grey.
was raining hard _______ I got there.
was worried because little Alice was ill, especially ______ father was away.
2.由bef ore和after引导的时间状语从句。注意before引导的从句不再用否定式的谓语，
并且当b efore引导的从句位于主句之后，有时译成“就，才”。还要注意主句和从句之间的
时间关系。当主 句用将来时，从句总是用现在时；如果before引导的从句谓语用的是过去
时，则主句动词多用过去 完成时，这样以便体现动作发生的先后。After表示主句动作发生
在从句动作之后。主句和从句的动 作的时间关系正好与before引导的从句相反。如：
It will be four days before they come back. 他们要过四天才能回来。
Before we went home, we had finished the work.回家之前，我们还得完成工作
After we had finished the work, we went home.完成工作之后，我们回家了。（从句用过去
完成时，主句用一般过去时）
注意 before在下列句型中的使用：
It waswill be + 一段时间 + before + 从句
It wasn’twon’t be long before + 从句

before一词在不同的句型中就有不同的意思，如：“在??之前”、 “过了??才”、“没??
就”、“不知不觉就??”等。
考点翻译练习：
Before I could say a word，he had called my
name. 。
We had sailed four days and four nights before we saw
lands. 。
We waited a long time before the train
arrived. 。
3.由till或until引导的时间状语从句。till和until一般情况下两者可以互换 ，但是在强调
句型中多用until。并且要注意的是：如果主句中的谓语动词是瞬时动词时，必须用否 定形
式；如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不
同 。如：
I didn't go to bed until（till）my father came back.直到我父亲回来我才上床睡觉。
It was not until the meeting was over that he began to teach me songs.直到散会后他才教
我歌。
Please wait until I arrived.在我到达之前请等我。
4.由since引导的时间状语从句。 since引导 的从句的谓语动词可以是延续性的动词，又
可以是瞬时动词。一般情况下，从句谓语动词用一般过去时， 而主句的谓语动词用现在完
成时。但在It ishas been ＋时间＋since从句的句型中，主句多用一般现在时。
I have been in Beijing since you left. 自从你离开以来，我一直在北京了。
若sin ce引导的状语从句的谓语动词是持续性动词或表示状态的动词时，则从句表示的时间
是“从那持续动作 或状态结束时算起”。
It is four years since my sister lived in Beijing. 我妹妹不住北京有四年了。
至于It is +一段时间+since…的句型与It has been +一段时间+since…意思相同。前者是规范说法，
后者是口语说法。
考点翻译：
1.

I have not heard from him since I lived in
Shanghai. 。
2.

school. 。

minute, every time, each time, the minute, the day, the week, the year, the first
time,next time, any time, the last time, all the time, from the time, by the time,

“一…就…”。等引导的时间状 语从句。这些连词都表示“一……就”。
I recognized you the minute I saw you. 我一见到你，就认出了你。
注意：hardly(scarcely, rarely)…when, no sooner…than相当于as soon as之意。主
句用过去完成时，从句用一般过去时。当hardly, scarcely, rarely和no sooner位于句首
时，主句应用倒装语序。
Hardly ／ Scarcely had I closed my eyes when someone knocked at the door．我刚一闭
上眼，就有人在敲门了。
6.由by the t ime引导的时间状语从句。注意时态的变化：在一般情况下，如果从句的谓
语动词用一般过去时，主句 的谓语动词用过去完成时；如果主句的谓语动词用一般现在时，
主句的谓语动词用将来完成时。如：
By the time you came back, I had finished this book.到你回来时，我已经写完这本书了。
注意：在时间状语从句中，不能用一般将来时、过去将 来时态或将来完成时，而要用相应的
一般现在时态、一般过去时或现在完成时来代替。如：
学习时间状语从句应注意以下几点：
1. 时间状语从句中一般不使用将来时态，尽管主句使用将来时态，一般使用一般现在时态
或

stopped. 等车停稳后才下车。
2. 主句使用过去进行时或过去完成时，或是waswere about to do Sth. ,后面从句使用 when
