状语从句的条件和时间关系解析

状语从句的条件和时间关系解析

状语从句的条件和时间关系解析状语从句是复合句中的一种从属成分,用来修饰主句中的动作或状态。

状语从句可以表示条件、时间、原因、目的、结果等关系。

在本文中,我们将重点探讨状语从句在条件和时间关系中的应用。

通过分析状语从句的用法和例子,我们可以更好地理解状语从句的条件和时间关系。

一、条件关系在表达条件关系时,状语从句一般与主句之间存在着一种前后因果关系。

具体的条件关系有以下几种:1. 如果/假如/要是...,就...例如:如果你明天来我家,我就给你准备好晚饭。

在这个例子中,状语从句“如果你明天来我家”表示条件,主句“我就给你准备好晚饭”表示结果。

2. 除非...,否则...例如:除非你努力学习,否则你不会通过考试。

在这个例子中,“除非你努力学习”是状语从句表示条件,“否则你不会通过考试”是主句表示结果。

3. 只要...,就...例如:只要你努力,就一定能成功。

在这个例子中,“只要你努力”是状语从句表示条件,“就一定能成功”是主句表示结果。

二、时间关系状语从句在时间关系中主要用来表示主句中的动作或状态发生的时间。

常用的时间关系有以下几种:1. 当...时/每当...例如:当他看到那个小孩的时候,他立刻上前帮助了他。

在这个例子中,“当他看到那个小孩的时候”是状语从句表示时间,“他立刻上前帮助了他”是主句表示动作。

2. 一直到...才...例如:我等了好几个小时,一直到天黑才回家。

在这个例子中,“一直到天黑”是状语从句表示时间,“我等了好几个小时,才回家”是主句表示动作。

3. 在...之前/之后...例如:在我们离开之前,请确保所有的灯都关闭。

在这个例子中,“在我们离开之前”是状语从句表示时间,“请确保所有的灯都关闭”是主句表示动作。

总结:通过以上的例子,我们可以看出,状语从句在表示条件和时间关系时,能够很好地连接主句与从句,使句子结构紧凑,表达清晰。

熟练运用状语从句,可以使文章更丰富多样,也可以增强语言表达的准确性。

八种状语从句

八种状语从句

八种状语从句状语从句在句中作状语,修饰主句中的动词、形容词和副词等。

按其作用和意义可分为时间、原因、目的、结果、条件、让步、方式、比较八种。

下面对这八种从句的要点加以总结。

一、各类状语从句的引导词及易混词的区别。

1. 时间状语从句1) 引导词(1)表示“当……时候”:when, while, as, whenever(2)表示“一……就……”:as soon as(3)其它:after, before, since, until, by the timeWhenever he comes, he brings a friend. 他每次来都带个朋友。

I want to see him as soon as he arrives. 他一来我就要见他。

I went to bed after I finished my homework. 我做完家庭作业之后才睡觉。

2) 易混引导词when, while, as 的区别when既可指“时间点”,与瞬时动词连用,也可指“时间段”,与延续性动词连用(这时可与while互换)。

如:When he came in, his mother was cooking. 他进来时,他妈妈正在烧饭。

When(While)we were at school, we went to the library every day. 我们在校求学时,每天都到图书馆去。

while 只表示时间段,因此while从句的谓语动词要用延续性动词。

as 与when 用法相似,但着重强调主句动作与从句动作同时发生,有“随着……”或“一边……一边……”之意。

She sang as she went along. 她边走边唱。

As you get older, you get more knowledge.随着年龄的增长,你获得的知识就越多。

掌门1对1教育高中英语时间、原因、条件状语从句一.when, while 和as 引导时间状语从句的区别用法(一)when 的用法when 从句的A事件,相当于另一个事件B发生的时间点。

(也就是说,when 从句的重点不在动作本身发生的状态,而只是把它作为一个时间点,)所以when 多数情况下用的是一般过去时,则不用正在进行时。

(口头练习)When I got to the airport, the guests had left.Why do you want a new job when you have got such a good one already?(二)while 的用法while 从句的侧重点在于描述动作正在发生的状态,(它的意思是:当while 事件正在发生的时候,另一件事如何如何。

)所以,while 从句一般用的是正在进行时。

而另一件事的状态根据具体情况而定。

(口头练习)1. While my wife was reading the newspaper, I was watching TV.2. While Jim was mending his bike, Lin T ao came to see him. 从时间的角度来看,while 表示的是一段时间,是一个过程。

趁热打铁。

Strike while the iron is hot.(这句话中,是说趁着铁是热的这段时间,赶紧打铁。

如果换成when 意思就变了,相当于说铁只热了一下,打一下,然后铁就冷了。

这显然不符合文意。

)(三)as 的用法as 从句表示的也是一件事情正在发生,另一件事也正在进行当中。

as 从句用的一般不用正在进行时,而只是一般过去时。

可以翻译成“边……边……”。

(口头练习)As my mother sang those old songs, tears ran down her cheeks. The students took notes as they listened. as 表达的事件,往往只是主句动作发生的背景或条件时,as 只是一个次要的时间说明,常常翻译成“随着……”之意。

1. As the time went on,the weather got worse. 随着时间的推移,气候更加糟糕。

2. The atmosphere gets thinner and thinner as the height increases. 随着高度的增加,大气越来越稀薄。

(少数情况下,如果强调动作正在发生,as 从句也可以用正在进行时。

The sad mother sat on the roadside, shouting as she was crying. 伤心的妈妈坐在路边,边哭边叫喊。

)Exercise :1.the day went on, the weather got worse.2. Just I stopped my car , a man came up to me.3.the manager comes here for a visit next week, I’ll talk with him about this.4. —I'm going to the post office.— you're there, can you get me some stamps?Key: As When/as When While二.until 和till 的用法区别 肯定形式表示的意思是“做某事直至某时”,动词必须是延续性的。

否定形式表达的意思是“直至某时才做某事”。

动词为延续性或非延续性都可以。

肯定句:I slept until midnight.Wait till I call you.否定句:She didn't arrive until 6 o'clock.Don't get off the bus until it has stopped. 公共汽车停稳后再下车。

I didn't manage to do it until you had explained how. 直到你教我后,我才会做。

区别: until 可用于句首,而till 通常不用于句首;表示“直到…才”用untilUntil you told me, I had heard nothing of what happened. Not until…在句首,主句用倒装。

Man didn ’t know what heat is until the early years of the 19th century.Not until the early years of the 19th century did man know what heat is. Ididn ’t realize how much time I had wasted until I began to worl.Not until I began to work did I realize how much time I had wasted.三.表示“一……就……”的结构1.as soon as, once, directly, immediately, instantly, the moment, the instant, the minute2. hardly/scarcely…when/before, no sooner…than (主句常用过完)As soon as I got home, it began to rain.=I had hardly / scarcely got home when it began to rain.=I had no sooner got home than it began to rain.注意:如果hardly, scarcely 或no sooner 置于句首,句子必须用倒装结构。

Hardly / Scarcely had I got home when it began to rain.总结:1)as, when 引导短暂性动作的动词。

2)当从句的动作发生于主句动作之前,只能用when 引导这个从句3)从句表示“随时间推移”连词能用asNo sooner had I got home than it began to rain.3.Instantly, immediately, directlyI got up to open the door immediately the bell rang.4.The moment, the instant, the minuteWe thrilled with joy the very minute we set foot on the soil of our motherland.Exercise:Fill in the blanks with proper words.1._________ he comes tomorrow, I shall ask where he has been. 2._________ he was speaking, everybody listened carefully. 3.I saw her just _________ she was getting off the train. 4.Have a good look at that man _________ you pass him. 5.It was already eight o'clock _________ we got there.6.
