高考英语语法之：时间状语从句
三大从句是高中最重要的语法点，没有“之一”。对于从句的考察贯穿高考英语试卷的始终，从第一个单项听力，到最后的写作。名词性从句、状语从句以及定语从句三者重要性不分伯仲。
但正如大家知道的，“三大”之一的状语从句，种类繁多。时间、地点、原因、结果、条件、让步、条件、比较、方式9种，基本上大家在经历了学校课堂的洗礼后，也都耳熟能详。殊不知，这9种之中，对于高考来说，重要性的区别是很大的。考频为证，以2006-2010年5年全国高考18个省市的19套卷子的单项选择题为例，涉及到状语从句的题目共有93道，其中时间状语从句考到了24题，条件状语从句26题。孰轻孰重，不多赘述。
与名词性从句不同，状语从句最简单也最直接的办法就是牢固掌握相关连词或者连词词组的中文意思。以时间状语从句为例，需要掌握的连词范围如下：
when/while/as/before/after/until/as soon as
1、when: 做“当……的时候”讲，是个尽人皆知的意思，所以高考是不会考到的。相对的，会考到“突然，就在那时”的意思，用以表示从句动作发生的突发性。
2010年全国II卷7题：
Tom was about to close the windows _____ his attention was caught by a bird.
A. when
B. if
C. and
D. till
鉴于大家都看得明白，不多赘述。
2、while：当初很多老师讲的时候，告诉我们while和when的区别在于前者连接的主从句一定都用进行时态，是不对的。而且，这更不是判断二者区别的办法。
正解：while在同做“当……的时候”讲时，侧重表达主从句动作的对比关系，翻译成“而”字。
e.g. He has b een a father of 2 babies while I?m still single.
2010年全国I卷25题：
Mary made coffee her guests were finishing their meal.
A．so that B. although C. while D. as if
例句和真题都反复证明了不该在主从句时态上纠结，表示前后动作的对比才是王道。
3、as：同做“当……时”的时候，as更强调主从句动作同时发生，译作“一边……一边……”
e.g. As he works, he studies. 他半工半读（一边工作一边读书）。
4、before VS after: 这两个连词大家貌似很熟，但其实是历年高考中大家最容易犯错的两个连词。例如可以试问自己下：before后面接先发生动作后发生动作？after后面接先发生后发生？我猜90%以上的各位至少会纠结10秒钟以上的时间。
做此类时间状语从句题的罩门就是摸清动作发生的先后顺序。所以牢记“…前?（before）接后，…后?（after）接前”这样的口诀，可以瞬间解决问题。Plus: 关于这两个连词还有一个“损招”：大量的真题证明，只要4个选项中before和after同时出现，则一定从中二选一，没有反例！
5、until: 同样也是一个高频考点。大多数同学都认识作“知道”讲，而且相信很多同学对“not…until…”结构作“直到……才……”讲的这种说法耳熟能详。但真题证明了：首先，高考中如果until成为正确项的时候，把“直到”的意思翻到句子中是翻译不通的；而且，以下句为例：The baby won?t stop crying until his mother tells him a story. 是译作“小孩儿不会停止哭泣直到他妈给他讲个故事”，还是“直到他妈给他讲故事，孩子才停止哭泣”？这也是让很多人头大的问题。
综上所述，给出正解：无论肯定句还是否定句，until的意思都是“过则反主”，即“过了从句所发生的动作后，则发生与主句相反的动作”。
上句正解：过了他妈给他讲故事这个动作时间，小孩儿就停止哭泣了，但主句说不会停哭，所以选择until。
6、as soon as: 这个连词词组就比较简单，译为“一……就……”，没啥技术含量，而且历年真题中一定与as long as（只要）和as far as（就……而言）同时出现在选项中。
另外，做状语从句的题目时，切忌直接将连词的意思逐个带回题目中翻译，因为往往被认为是带入翻译最通顺的选项，其实是强干扰项，这同样也是绝大多数人选错的原因。相反的，拿到题目后第一时间要做的是通过翻译设空点前后的主从句，找出两者之间的内在逻辑关系（因果、时间等），从而选择表示相应的逻辑的连词或连词词组。

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。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。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。

状语从句 一．分类： such+n.+that（如果……以致）that（所以，因此）
让步状语从句：though/although不可同but连用。 though/although （虽然）however （可是）even though/if（即使） no matter+what/which/where/who/when =whatever/whichever/wherever/whoever/whenever （不论什么/哪一个/哪里/谁/何时） 比较状语从句：as （正如）as…as（和……一样）not as/so … as （不如……）than（比……更）the+比较级…+the+比较级（越……越……） 条件状语从句：if（假设）unless（如果不）so long as（只要）on condition that （如果） * 方式状语从句：as（像……那样地）just as（正像）as if（好像）as though（好像） 二．各种状语从句的简化方法： 1 作状语。 】 例：After she sang，she left the rich man's house．= After singing，she left the rich man's house．2．以as soon as引导的状语从句的主语若与主句主语一致时，从句等于on+doing sth.,作状语，此时的动词为非延续性动词。 例：Mary began to operate on the wounded soldiers as soon as he arrived at the village． = Mary began to operate on the wounded soldiers on arriving at the village． 3．时间状语从句和条件状语从句的主语和主句主语一致时，有时可简化为不定式作状语。 例：She stopped when she saw her husband．= She stopped to see her husband．If you want to understand the farmers，you must go to the countryside． = To understand the farmers，you must go to the countryside． 4．结果状语从句和目的状语从句的主语与主句主语一致时，可以简化为不定式作状语；若两者主语不一致时，则应简化为不定式的复合结构作状语。 例：He was so tired that he couldn't go any further．= He was too tired to go any further． I came here so that I could ask some questions．= I came here(in order) to ask some questions．5．以when，while引导的时间状语从句和以if引导的条件状语从句的主语若与主句主语一致时，从句等于when/while/if +doing sth.作状语，表示谓语动作发生在该状语动作的进行过程之中。 。 例：When he turned on the radio，he found it broken．= When turning on the radio，he found it broken．While she was walking along the street，she was hit by a car．= While walking along the street，she was hit by a car． 6．原因状语从句的主语与主句主语一致时，可简化为分词短语作状语。 例：Since l didn't know Chinese，I tried to speak to her in English．= Not knowing Chinese，I tried to speak to her in English． 注意：形容词短语也可作表示原因的状语，来代替原因状语从句，放在句首、句末均可，但一般应加逗号。 例：As he was thirsty and eager to get a little rest，he went into the tea-house． = Thirsty and eager to get a little rest，he went into the tea-house．
