常见的时间状语从句用法一览

时间状语从句是一个非常重要的语法项目，常见的用法主要有：
1.由when, while, as引导的时间状语从句。
When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候，你就是在开始知道一些事物了。
When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！
Strike while the iron is hot. 趁热打铁。
Will you watch my clothes while I have a swim. 我游泳的时候，请你照看一下我的衣服。
You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候，你就能感觉到空气在流动。
Our headmaster laughed as she spoke.我们的校长边谈边笑。
注意：when, while和as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。
When I lived in the countryside, I used to carry some water for him.当的住在农村时，我常常为他担水。
We were about to leave when he came in.我们就要离开，就在那时他进来了。
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. (was reading是延续性的动词，was reading和was watching同时发生)
I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。
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。（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）
2.由before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before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。
Einstein almost knocked me down before he saw me.爱因斯坦几乎把我撞倒才看到我。
My father had left for Canada just before the letter arrived.我父亲恰好在信到之前去加拿大了。
They had not been married four months before they were divorced. 他们结婚还不到四个月就离婚了。
After you think it over, please let me know what you decide.你仔细考虑过以后，告诉我你是怎样决定的。
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）
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 English.直到散会之后他才开始教我英语。
I worked until he came back.我工作到他回来为止。
I didn't work until he came back.他回来我这才开始工作。
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 is ＋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。
Where have you been since I last saw you? 自上次我和你见面以后，你到哪里去了？
It is four years since my sister lived in Beijing. 我妹妹不在北京住有四年了。
It is five months since our boss was in Beijing.我们老板离开北京有五个月了。
5.由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引导的时间状语从句。这些连词都表示“一……就”。
I will go there directly I have finished my breakfast. 吃完早饭，我立即到那里去。
The moment I heard the news, I hastened to the spot.我一听到消息，马上赶到了出事地点。
As soon as I reach Canada, I will ring you up. 我一到加拿大，就给你来电话。
注意：hardly(scarcely, rarely)…when / before, 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。
He had no sooner arrived home than he was asked to start on another journey. 他刚到家，就被邀请开始另一旅程。
No sooner had the sun shown itself above the horizon than he got out of bed to commence work.太阳刚从地平线上升起，他就起床劳动去了。
Hardly had I sat down when he stepped in.我刚坐下，他就进来了。
He had hardly fallen asleep when he felt a soft touch on his shoulder.这个阿拉伯人刚要入睡就感到肩膀上被轻轻一触。
6.由by the time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。
By the time you come here tomorrow, I will have finished this work. 你明天来这儿的时候，我将已经完成此工作了。
7.由each time, every time和whenever引导的时间状语从句。
Each time he came to Harbin, he would call on me. 他每次来哈尔滨，总是来看我。
Whenever that man says“To tell the truth”, I suspect that he's about to tell a lie.每当那个人说“说实在话”的时候，我猜想他就要说谎了。
You grow younger every time I see you. 每次遇到你，见你更年轻了。
8.由as long as和so long as引导的时间状语从句。这两个连词表示“有多久……就多久”。
You can go where you like as long as you get back before dark. 你可以随意到哪里去，只要在天黑以前回来就行。
I will fight against these conditions as long as there is a breath in my body只要我一息尚存，我就要反对这种境况。

八、例题解析
1) D无论在语法上还是语意上均正确，而若选A和B，则只是两个句子的无谓罗列，这在英语中是绝对不允许的，而C是一个名词短语，也不符合要求。
2) B对。本句是由连词before引导的时间状语从句，其中的long是副词，修饰before，“long before”意为“早在…之前”，long before易与before long相混淆，before long相当于介词短语，意思是“不久”。
3) B 对。由于逗号后面是一个完整的句子，则本句空白处成分可能是介词短语、分词短语或状语及状语从句，在备选答案中，只有B 具备状语从句的条件。whenever是when的强调式表示“无论什么时候”。
4) A错。本句含“so…that”句型，“so”是副词，它后面可接形容词或副词，而“that”后要接表结果的状语从句，故应将“too”改为“so”。
5) B错。改为“so”。
6) C对。本句主语为“Hippopotamuses”，谓语是“do not feed”，逗号之间显然为插入成分，A和B不符合要求，D虽表面上是非限定定语从句修饰前面的成分，但which指主语，马上又接主语they，成了“双主语”，故应排除。C是由连词although(尽管) 引导的让步状语从句作插入语，完全符合条件，故应选C。
7) B对。逗号后为一完整的句子，逗号前又出现了谓语，那么空白处一定缺起引导从句作用的连词和从句主语，B 完全符合条件，though的用法和although基本相同，意思也相同。C 好像是“that”引导的主语从句，可后面接的并不是谓语，而是一个句子，故C 也不对。D 貌似“it is…that”强调句，但句中缺that，且语法语意混乱。
8) B对。A不对，因为“because of ”(因为) 是成语介词，后面不可接句子，而C和D均不合语法，只有B正确，“it”指代“neon”。
9) C对。本题中的四个选项都是连接词，即都可以引导后面的从句，从语法来说，它们都正确，但从语意及逻辑上看，显然以“〔C〕 because”(表“原因”) 切合题意。
10) B对。本句缺能引导一个从句的连接词，只有B符合条件。
11) C对。whether作为连词，只能放在从句句首，故B 和D 都不符合语法。虽然A中的whether放置于句首，但A 不是一个句子，因此只有C 中的whether才引导了一个状语从句，“whether…or not”在此处表示“无论…”。
12) A对。“where”引导的是地点状语从句，表示“在大西洋通过赤道的地方”。
13) B对。“as claws protect…”表示“正如爪或钳保护…一样”，as引导的是方式状语从句。A 明显不对。C 多“do”，D 好像是“so”引导的倒装句，但“so”不仅无所指代，因为后面不缺任何成分，而且在用“so”倒装句时，“so”前面通常有逗号，并且是“so＋助动词(或情态动词等) ＋主语”结构。
14) A对。从句部分说完整为“When they (glasses) are well fitted”，其中的“they are”被省略掉了。D 中的“If well fitted”本来也正确，但后面多“when”。
15) A对。although后省略了“they (bones) are”，apparently(明显地)是副词，修饰后面的形容词rigid。D 中的are和they顺序有误，否则也同样正确。
16) D对。本句为“连词＋现在分词”结构.
