each time 时间状语所用的时态
时间状语从句
时间状语从句常用的连词有：when，as，while，before，after，since，till，until，as soon as，once。
【例】
Before I could get in a word, he already gave orders.
我还来不及插话，他已经吩咐下去了。
After the students were all in the lab, the professor brought out three bottles.
在学生们全进入实验室后，教授拿出三个瓶子来。
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现在完成时态。
【例】
I'll go on with the work when I come back tomorrow.
我明天回来，我将继续做这项工作。
Please tell him about it when you see him back.
你看到他回来，就告诉他这件事。
（2）till/until引导时间状语从句，主句的谓语动词如是延续动词，可使用否定或不用否定，如果是不延续动词，必须使用否定形式。
【例】
He didn't go to bed until it was 12 o'clock last night.
他昨晚十二点才上床睡觉。
They worked until it was dark.
他们一直工作到天黑。
（3）as soon as, the moment, every time, each time, the minute, the instant, 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, immediately, instantly, directly等表示时间的词语，后面也可以接时间状语从句，表示“一……就……”。
【例】
I recognized you the minute I saw you.
我一见到你，就认出了你。
By the time he was fourteen, he had built his own lab.
到他十四岁的时候，他已建起自己的实验室。
（4）主句使用过去进行时或过去完成时，或是was/were about to do Sth. ,后面从句使用when从句，而且谓语动词使用一般过去时，这时when不当“当……时候”解，而当“突然”解。
【例】
They were working in the fields when it began to rain.
他们在地里正干着活时，天突然下起雨来。
He was about to leave when the telephone rang.
他刚要走，突然电话铃响了。
1.由when, while和as引导的时间状语从句
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”。例如：
When she came in, I stopped eating.她进来时，我在吃饭。(瞬时动词)
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。（延续性的动词）
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。例如：
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。（对比）
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。例如：
We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”）
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。
before: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。例如：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。till不可以用在句首，而until可以放在句首。例如：
I won't stop crying until you let me go.你不教我走我就一直喊叫。
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。例如：
I have been in Beijing since you left. 自从你离开以来，我一直在北京了。
It is four years since my sister lived in Beijing. 我妹妹不在北京住有四年了。
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”。例如：
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。例如：
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；如果从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。例如：
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。例如：
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“只要“例如：
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。
一般将来时，Each time I see you ,I will remrmber the happy time we spent together.主句有will表示是将来时，那么从句也该用同样的时态will see，但从句有用一般现在时代替一般将来时的性质，故变为see。
一般过去时，I had three tries and failed each time.
each time引导的从句多若有将来意义，必用主将从先。
若有过去意义，则用过去式。如：Each time she moved her leg, she let out a moan.
每次她动一下腿，就发出一声呻吟。
这句话中将来的含义是由 will 一词看出来的，并不是each time。其实each time本身并没有什么时态，意思是"每次………的时候"，做状语使用，关键看后面的句子来判断时态。
刘芳妇科：[答案] each time 有的,表示每一次……的时候(相当于when) Each time I see you,I will remember the happy time we spent together. 每一次我见你,就会想起我们一起度过的快乐时光.

克孜勒苏柯尔克孜自治州18451988685： 关于时间状语 - ？
刘芳妇科： 首先我想说一下,你的第一句话有语法错误:spend 时间 on sth 或者是 in doing sth,而没有接听to do形式的. 接下来回答你的问题,about是一个类似于介词的副词表示大约,所以用于修饰时间状语,因为这里的时间已不仅仅是名词而是做了状语. for接时间表是所做的一件事情持续的时间长短的,所以要加for这个介词. next year:就是明年,不表示持续的性质. for one year 指的是持续了一年,有持续进行了这么长时间的意思在其中.
