9、语从句的分类。1. 时间状语从句用法要点。（1）as、when 、while 用法一览表。类别 作 用 例 句asas 表示“当的时候” ，往往和when/ while 通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。She came up as I was cooking.(同时)The runners started as the gun went off.(几乎同时 )when(at or during the time that )既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。It was raining when we
10、 arrived.(指时间点)When we were at school, we went to the library every day.(在一段时间内)whilewhile 意思是“当的时候”或“在某一段时间里” 。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在 when 表示 a period of time 时，两者可以互换。Please dont talk so loud while others are working.He fell asleep while/when reading. Strike while the iron i
11、s hot.(用 as或 when 不可，这里的 while 意思是“趁”)凡是从句都必须有引导词，引导时间状语从句的词有 when, before, after, until, as soon as, while 等，具体用法如下：1. when 意为“当时”，引导时间状语从句，表示主句的动作和从句的动作同时或先后发生。例如： I feel very happy when you come to see me. 你（们）来看我时，我感到很高兴。When you are crossing the street, you must be careful. 你（们）过街道时，一定要小心。when

14、rday.昨天离开学校之前，我们打扫了教室。 He had been a cook before he went to college . 他上大学前曾当过厨师。after 意为 “在之后” ，引导时间状语从句时，表示主句的动作发生在从句的动作之后。例如： After you use plastic bags, you mustnt throw them about. 你（们）用过了塑料袋之后，不准到处乱扔。He called me after he had finished his work. 他在工作完之后给我打了个电话。注：若主句和从句两个动作发生的先后顺序十分接近，那么也可以不用完成时
15、态，例如上面的第二句可改成：He called me after he finished his work. 3. since 引导的时间状语从句，译为“ 自从”，主句常用现在完成时，从句常用一般过去时。例如：We have made many dumplings since we began to cook. 自从我们开始做饭起，我们已经包了许多饺子了。We havent seen each other since we parted . 我们自从分手以后一直没见过面。注：常用句型：It is +时间段 +since 从句 译为：自从 有多长时间了。例如：It is six years si
16、nce she graduated from the university. 自从她大学毕业已有六年的时间了。4. until 意为 “直到时”，引导时间状语从句时，表示主句的动作发生在从句的动作之前。当主句的谓语动词是持续性动词时，主句常用肯定形式；当主句的谓语动词是非持续性动词时，从句常用否定形式, not. until. 意为“直到才”，这时的 until 可以用 before 来替换。例如：Ill stay here until you come back. 我会呆在这里，直到你回来。(stay 表示的动作可以持续) He didnt go to bed until he finish
17、ed his homework.他直到做完作业才睡觉。 (go to bed 表示的动作不能持续) 5. as soon as 意为“ 一就”，表示从句的动作一发生，主句的动作马上就发生。例如： Ill tell him about it as soon as he comes back.他一回来我就告诉他这件事。6. while 引导的时间状语从句，常译为“与同时，在期间”，while 的从句中常用延续性动词或表示状态的词。例如：They rushed in while we were discussing problems. 当我们正在讨论问题时，他们冲了进来。Father was cle
18、aning the car while I was playing computer games. 当我正在打电子游戏时，爸爸正在清洗汽车。注：while 也可以作并列连词，表转折的关系，相当于 but，译为“然而”。 例如：I like listening to music, while my brother likes doing sports. 我喜欢听音乐，而我的兄弟爱好运动。7. till 和 until 引导的时间状语从句，译为“直到为止”，not till / until 引导的时间状语从句，译为“ 直到才” 。前者强调主句动作的结束，用延续性动词，后者强调主句动作的开始，用点动
19、词。例如：I will wait for my friend until / till he comes. 我要一直等到我朋友来。We wont start our discussion until / till he comes. 我们要等到他来了，再开始我们的讨论。2. 条件状语从句用法要点。 我们主要看一下由 if 引导的条件状语从句。if 意为“如果”，引导条件状语从句时，表示假如有从句的动作发生就(不)会有主句的动作发生。例如： If it doesnt rain tomorrow, we will go there by bike.如果明天不下雨，我们就骑自行车去那里。If I g

21、常用 as 或 since；as 和 since 的从句常放在主句之前，而 because 的从句常放在主句之后。eg.Why did you go? I went because Tom told me to go. 你为何去？那是因为汤姆叫我去。He was angry not because we were late but because we made a noise. 他很生气不是因为我们来迟了，而是因为我们弄出了声音。As it was raining hard, we had to be indoors. 由于雨太大，我们只好呆在家里。Since you feel ill, y
22、oud better not go to work. 既然你感觉不舒服，你最好不要去上班了。5. 目的状语从句用法要点。常用的引导连词有 so that, that 和 in order that 译为：以便，为了，目的是。例如：Please speak more slowly so that we can make full notes. 请讲慢一点，以便我们能作详细笔记。I shall write down your address that I may not forget. 我要把你的地址记下来，以免忘记。I sent the letter by air mail in order t

24、马路时要小心。Put up your hand if you have any questions to ask. 如果你们有问题要问的话，请举手。The traffic must stop when the lights are red. 红灯亮时，车辆必须停下。2. 若主从句谓语动词都是陈述过去，那么主从句都可以用一般过去时。例如： She could sing when she was four years old. 她四岁的时候就会唱歌。【语法过关】1I was drawing a horse _the teacher came in.
