但是instant做先行词是可以的,关系副词用when:the instant when……意思是当……的时候Your lights will come on the instant when you enter the door。
6.本句中还有一个介词短语along with 和……一起,就是说和灯一起亮的,还有你喜欢的音乐或者电视节目。

高中英语语法总结-状语从句

状语从句状语从句是一种副词性从句,通常由一个从属连词或一个起连词作用的词组引导。
状语从句1. 时间状语从句常见的连词(组):when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。
可以引导时间状语从句的副(介)词(短语)或名词短语:directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。
注意点如下:(1) when, while, as引导的时间状语从句as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。
when(at or during the time)既可以表示在某一点的时候,又可以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。
while强调一段时间,仅表示从句和主句的动作同时发生,并且有延续意义,该从句中的动词一般要用延续性动词,从句中常用过去进行时态或一般过去时态;当when表示a period of time时,两者可以互换。
She came up as I was cooking.(同时)在我做饭时,她走了过来。
When we were at school, we went to the library every day.(在一段时间内)当我们在学校时,每天都去图书馆。
While they were watching TV, I was preparing myself for the coming examination.他们在看电视,而我在为即将到来的考试做准备。
【语法讲解】高中英语--状语从句专题讲解(详细)

主句如果是否定句,则此时主句谓语动词用非延续性动词,表示主句的动作从从句表示的时间点才开始,即“直到…才…”
Ididn’t knowanything about it until you told me(否定句,谓语为非延续性动词)
2)主句是肯定句时
主句如果是肯定句,则此时主句谓语动词用延续性动词,表示主句的动作直到从句表示的时间点就结束,即“直到…为止”。
No sooner had he reached home than it began to rain.
= He had no sooner reached home than it began to rain.
Hardly had I told him the news when he stopped listening.
=I hardly told him the news when he stopped listening.
地点状语从句
地点状语从句的引导词有when和wherever。
where, wherever指具体地点时,从句可用于主句之前或之后;
where, wherever表示抽象概念的含义时,从句需放在主句前。
While wewere waiting forthe bus, it was raining heavily.(延续性)
while和as常表示从句的动作与主句的动作同时发生,而when表示从句的动作发生在主句动作之前、之后,也可同时发生。
Theyrushed inwhile/as wewere discussingproblems.(同时发生)
2)从句谓语动词不同,表达的意义不同。
since引导的从句谓语如果是延续性动词或表示状态的动词,则从句表示的时间是从该动作或状态结束时算起。

时间状语从句
一、时间状语从句的定义
用表示时间的连词连接一个句子作状语,这样的主从复合句就是时间状语从句。
连接时间状语从句的连接词有:when, before, after, while, as soon as, until, since...... 假如主句是一般将来时,从句只能用一般现在时表示将来意义。
二、时间状语从句-从属连词
引导时间状语从句的一般类从属连词有when(当……时),while(在……期间),as(当……,一边……一边……),before(在……之前),after(在……之后),since(从……以来),till/until(直到),whenever(无论何时),as soon as(一……就)
留意: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。
例句:I’ll telephone you as soon as I get there. 我一到达那里就打电话给你。
三、时间状语从句-时间状语
1、一般现在时every …, sometimes, at …, on Sunday,
2、一般过去时yesterday, last week, an hour ago, the other day, in 1982, just now
3、一般将来时next…, tomorrow, in+时间
4、现在完成时for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always, recently
5、过去完成时before, by, until, when, after, once, as soon as
6、过去进行时this morning, the whole morning, all day, yesterday, from nine to ten last evening… when, while
7、将来进行时soon, tomorrow, this evening, on Sunday, by this time, tomorrow, in two days, tomorrow evening
四、时间状语从句-时态问题
时间状语从句常用的连词有:when,as,while,before,after,since,till,until,as soon as,once。
1、时间状语从句中一般不运用将来时态,尽管主句运用将来时态,一般运用一般现在时态或现在完成时态。
例句:I'll go on with the work when I come back tomorrow.我明天回来,我将接着做这项工作。
2、till/until引导时间状语从句,主句的谓语动词如是持续动词,可运用否定或不用否定,假如是不持续动词,必需运用否定形式。
例句: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。
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……”。
4、主句运用过去进行时或过去完成时,或是was/were about to do sth.后面从句运用when从句,而且谓语动词运用一般过去时,这时when不当“当……时候”解,而当“突然”解。
五、时间状语从句的用法
when,while和as都有“当……时候”的意思,但在不同语境中意义也有所不同。
1、when 的用法
假如只从现象来看,when从句用的最多的是一般过去时,而主句的时态没有限制,依据详细状况而定。
例句:When he was a child he was always trying out new ideas. 他小时候就经常试验一些新的设想。
依据以上例句,我们可以总结出一点:when从句的A事务,相当于另一个事务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多数状况下用的是一般过去时,则不用正在进行时。
因为假如用正在进行时,它表示的就是一段时间而不是一个时间点了。
所以,when从句的动词大多是瞬时动词的说法也可以参照。
事实上,when从句也可以有其它的时态,但几乎也不用进行时,因为它也只是作为一个时间参照点。
2、while 的用法
相比于when 来说,while从句的侧重点就不一样了。
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事务正在发生的时候,另一件事如何如何。
所以,while从句一般用的是正在进行时,而另一件事的状态没有硬性的要求,依据详细状况而定。
3、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。
但与while从句不同的是,as从句用的一般不用正在进行时,而只是一般过去时。
as从句一般可以翻译成“边……边……”。
但as表达的事务,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,不像while从句有强调while动作本身的意思。
因此,as经常翻译成“随着……”之意。
例如:As the time went on,the weather got worse. 随着时间的推移,气候更加糟糕。
4、when, while, as 的互换
假如从句动作和主句动作同时发生,并且从句动作为持续性动词时,when,while,as 可以互换运用。
5、比较while, when, as
1)as, when引导短暂性动作的动词。
例句:Just as / Just when / When I stopped my car, a man came up to me. 我刹车后,有一个人向我走来。
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,不行用as 或while。
例句:When you have finished your work, you may have a rest. 干完活后,你可以休息一下。
3)从句表示“随时间推移”连词能用as,不用when 或while。
例句:As the day went on, the weather got worse.日子一每天过去,天气越变越坏。
6、比较until和till
until和till意义相同,确定形式表示的意思是“做某事直至某时”,动词必需是持续性的。
否定形式表达的意思是“直至某时才做某事”。
动词为持续性或非持续性都可以,但until 可用于句首,而till通常不用于句首,而且Not until…在句首,主句用倒装。
