高考状语从句知识点
高考状语从句知识点状语从句是高考英语中的一个重要知识点，掌握好它对于我们在高考中取得好成绩可是相当关键哦！今天咱们就来好好聊聊状语从句。
先来说说啥是状语从句。
简单来讲，状语从句就是用一个句子来充当状语。
那啥是状语呢？就好比咱们跑步的时候，给你加油打气的那些话，告诉你跑快一点、跑慢一点、往这边跑、往那边跑，这些起辅助说明作用的就是状语。
而用一个句子来做这个辅助说明的工作，那就是状语从句啦。
状语从句的种类那可不少，有时间状语从句、地点状语从句、原因状语从句、条件状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句和方式状语从句等等。
咱们先来说说时间状语从句。
比如说“When I was a child, I often played in the park” 这里的“When I was a child”就是一个时间状语从句，表示“当我还是个孩子的时候”。
再比如“While I was doing my homework, my mom was cooking dinner” 这里的“While I was doing my homework”表示“当我正在做作业的时候”。
记得我以前教过一个学生，叫小李。
有一次考试，他就因为时间状语从句丢了不少分。
那次考试有一道题是这样的：“＿_____ he came in, I was reading a book” 选项有“When、While、As”。
这小李啊，想都没想就选了“While”，结果就错啦。
后来我给他分析，这题应该选“When”，因为“While”强调的是动作的同时进行，而这里“came in”是一个短暂性动作，“reading a book”是一个持续性动作，所以要用“When”。
从那以后，小李可长记性了，每次遇到时间状语从句的题都会仔细分析。
接下来是地点状语从句。
像“Where there is a will, there is a way” 意思就是“有志者，事竟成”，这里的“Where there is a will”就是地点状语从句，表示“有意志的地方”。

1、While：“当...时候”，强调主句和从句的动作同时发生，或主句动作发生在从句动作进行的过程中。
从句常用延续性动词或表示状态的词。
The weather was fine while we were in Shanghai.My father was preparing a report while I was playing games.2、when:＂当……时＂，表示主句的动作和从句的动作同时或先后发生，从句的动词可用延续性动词，也可用非延续性动词。
It was raining when we arrived.when you read the poem a second time, the meaning will become clearer to you.3、as: ＂正当，一边……一边，随着＂，常指从句动作未结束，主句动作就发生；也可表示两个动作同时发生。
As time went on, his theory proved to be correct.We sang as we walked along.My cap was blown away as I stood up.4、Till/Until：用于肯定句时，表示＂直到……为止＂，从句动作结束时主句动作随之结束，主句必须为延续性动词。
否定句not...until/till中表示＂直到……才＂，主句常用短暂性动词，表示从句动作结束时主句动作才开始。

在这 种条件状语从句，动词不能用将来时态，而用一般现在时代替将来时，用现在完 成时代替将来完成时If you trust before you try, you may repent (后悔) before you die. If we catch the 10 o’clock train, we may get there by lunch time.Ⅱ 主句用祈使句，表示讲话人的请求或提议 If y ou w ish f or p eace, b e p repared f or w ar.Ⅲ 当从句表示到将来某个时刻已经完成或正在进行的动作时，动词可用现在完 成时或现在进行时。

If you pour oil on water, it floats.如果我们把红色和黄色混合起来，我们就得到了橘色。

Ⅰ与现在事实相反：从句谓语动词：v-ed/ were主句谓语动词：would/ could/ might/ should + v.例句：If she worked more slowly, she would not make so many mistakes.I shouldn't go there if I were you.Ⅱ与过去事实相反：从句谓语动词：had done主句谓语动词：would/ c ould/ might/ should + have d one例句：If I had realized t hat he was ill, I should have o ffered to help h im.If anything had happened, he would have let her know.Ⅲ与将来事实相反：从句谓语动词：were + to doshould + dov-ed/ w ere (从句中有表示将来的时间的状语)主句谓语动词：would/ c ould/ might/ should + have d one例句：If the rain were to go on, the crops would be in danger.If I saw/should see/were to see him t omorrow, I would invite h im h ome.Ⅳ当非真实条件状语从句中有s hould, had 或w ere 时，可以省略i f，而把s hould, had 或w ere 提至主语前。
Had I worked hard, I would have surly succeeded.Were s he m y d aughter, I w ouldn’t a llow h er t o s tudy a broad.Ⅴ错综时间条件句：有时非真实条件句谓语动词表示的动作与主句谓语动词表示的动作发生的时间不一致，这叫错综虚拟语气或混合虚拟语气，此时主句与从句的谓语动词的形式根据各自发生的时间来确定。
If I w ere y ou, I w ouldn’t h ave m issed t he c oncert l ast n ight.If you had told m e the news yesterday, I wouldn’t be so worried now.If you h esitated t his m oment, you might s uffer i n future.让步状语从句5A: while 尽管，虽然While w e d on’t a gree, w e c ontinue t o b e f riends.While I understand what you say, I can’t agree with you.B: b e 不管，不论相当于whether or notBe he friend or enemy, the law regards him as a criminal.C: if 即使，虽然If life there was f ull of hardship, it was full of joy and excitement.五 状语从句 考点时态问题过去完成 一般过去 过去将来 现在完成 一般将来 将来完成在条件，时间和让步从句中， 一般现在时表示一般将来时，用现在完成时表将来完成时，用一般过去时表 过去将时。
在 since 引导的时间状语从句中，动词一般都用一般 过去时，而主句常用现在完成时。
倒装问题（***） A:否定词开头； B:so 加 adj. 开头；C: as / though 引导的让步状语从句。
特别注意句式（看见必考倒装）Hardly … when … ，No sooner … than …， n/adj ， as he is 例句：Hardly had he got to the station when the train left. No sooner had he got to the station than the train left. Child a s h e i s, h e c an s peak s even f oreign l anguages.省略问题当状语从句的 主语和主句的主语一致时，可以省略状语 从句中的主语和系动词 be.1 2 3A: 连词+过去分词Don’t speak until spoken to.B:连词+现在分词Look out while crossing the street.C: 连词+ 形容词/ 其他常见的有if necessary, if possible, when necessary, if any 等④ 条件状语从句中 unless 和 if not 不可替换的情况如下A: 当i f…not 从句是一个非真实条件句时，unless 不能替换If she weren’t so silly, she would understand.B: unless 强调例外条件I will l eave a t 9, unless y ou want to g o e arlier.C: unless 从句为否定时Don’t ask me to explain unless you really don’t understand.⑤ 引导让步状语从句时，疑问词-ever 与“no matter +疑问词”完全相同，可以互换。
但是疑问词-ever 可以引导名词性从句，“no matter + 疑问词”则不可。
