高三复习 状语从句
【 专题眺望 】
知能目标： ① 状语从句中从属连词的正确使用。
② 主从句动词时态的一致性。 ③ 状语从句中的省略现象。
④ 状语从句与其他从句、非谓语动词作状语之间结构上的区别和相互转换。
命题规律： 状语从句在单项选择中的比重有所增大。侧重考查状语从句中的连词的选用，尤其是一些较特殊的连词、连词词
Child as/though he is, he knows a lot. 虽然他是个孩子，他懂得许多。 Much as/though I like it, I don ’t want to buy it. 尽管我很喜欢，我还是不会买的。
Try as/though he might, he wouldn ’t succeed.他试了也不会成功。 ③ as though 就象；仿佛 = as if ； even though 即使；尽管 = even if ， 例如：
1) Until 可用于句首，而 till 通常不用于句首。 Until you told me, I had heard nothing of what happened. 直到你告诉我以前，出了什么事我一点也不知道。
2) Until when 疑问句中， until 要放在句首。 ---Until when are you staying? 你呆到什么时候？ --- Until next Monday. 呆到下周一。
He felt no fear, for he is brave. 4. 比较 while, when, as
① as, when 引导短暂性动作的动词。 Just as / Just when / When I stopped my car, a man came up to me.
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，不可用
Though we are poor, we are still happy. 虽然我们穷，我们还是很幸福。 Though it ’s hard work, I enjoy it. 尽管是个苦差事，我喜欢。
He promised to phone. I heard nothing, though. 他答应打电话的，然而我什么也没听到。 ② as/though 引导的让步状语从句用部分倒装。可以把表语提前，也可以把状语提前，有时把谓语提前。若表语是名词时，名 词前常省略冠词。如：
组的含义和用法，如 in case, on condition that, the moment, however 等，主从句的时态呼应也是考查的重点。

连词
时间状语
when, as, while, before, after, since, once, till, until, once, as soon as, hardly
1) 强调对象＋ as/though＋主语＋其它部分，强调对象可以是表语 冠词。 例如：
(名词，形容词 )或状语 (副词 )。表语为名词时，前面通常不用
Tired as he is, he goes on with his work. Much as he likes her, he does get irritated with her sometimes.
7. no matter wh- 和 wh-ever 用法
no matter wh- 后面跟从句不跟短语， whatever/whoever/whichever 除了引导让步状语从句外，还可以引导名词性从句，而
whenever/wherever/however 只能引导让步状语从句。
8. 让步状语从句中的倒装形式为：
比较状语
as… as, than, the more … the m等ore
【 重难点透析 】 1. 时态呼应注意点 ① 状语从句用一般现在时表将来、用现在完成时表示将来完成时。如：
She will get married when she meets the right man. We won't climb up the mountain until rain has stopped. ② 在表示“刚 …… 就…… ”的句型 hardly … when… 和 no sooner … than … 中，主句常用过去完成时，从句常用一般过去 时，如果否定词置于句首，主句可用倒装结构。如： Hardly had I entered the room when I heard a loud noise. ③ It is +段时间 +since 从句， 从句里用过去时， It was +段时间 +since 从句，从句里用过去完成时， since 与短暂性动词连用时， 表示动作的开始， since 与延续性动词连用表示该动作的结束，翻译时通常译成该动词的反义词。
… when…,
no sooner … than, the momen等t
原因状语
because, as, since, now that, if/ when
地点状语
where, wherever
条件状语
if, unless, as long as, as far as, in case, supposing, on condition that, provided(that)
as 或 while 。
When you have finished your work, you may have a rest. ③ 从句表示 " 随时间推移 " 连词能用 as，不用 when 或 while 。
As the day went on, the weather got worse. 日子一天天过去，天气越变越坏。
注意：否定句可用另外两种句式表示。
1). Not until … 在句首，主句用倒装。 Not until the early years of the 19th century did man know what heat is. 直到 19 世纪初，人类才知道热能是什么。 Not until I began to work did I realize how much time I had wasted.
The roof fell before he had time to dash into the room to save his baby. 他还没来得及冲进屋子去救他的孩子，房顶就塌下来了。 I must write it down before I forget it. 趁我还没忘记，我得把它写下来。 Think before you leap. 三思而后行。 3. 原因状语从句的引导词 because, since 和 as 的用法
because 引导原因状语从句，语气最强，用来回答 why 的提问，放在主句的前后均可。 as 引导原因状语从句，语气比 because 弱，常译为“由于” ，只是附带说明，一般放在主句前面。
since 表示已知的或众所周知的原因，常译为“既然” ，相当于 now that。 注意在强调句中，只能用 because。because of 后边跟名词或代词。 关于表原因并列连词 for 引导的分句，主要是补充说明原因，解释另一分句，不可回答
How have you been since I saw you last time? (自从我上次见到你以后，你一向还好吗 ? ) It is (has been) just a month since he arrived here. ( 他来这里已经有一月了。 ) It is five years since I lived in Nanchang. (自从我不住在南昌以来已经 5 年了。 ) It is five years since I began to live in Nanchang. ( 自从我住在南昌以来已经 5 年了。 ) I haven't heard from him since I lived in Nanchang. (自从我离开南昌以来，已经 5 年了。 ) 2. before 的翻译较灵活，现将其译法归纳如下 ①“在以前” ，这时主句的动作发生在前，从句的动作在后 ②“（后）才” ，此时强调从句动作发生得晚或慢，主句的动作延续时间较长 ③“就；便；快” ，此时主句中的谓语动词为否定形式 ④“未就；还没来得及就” ，强调从句动作发生之前主句动作已经发生 ⑤“趁着” ⑥在某些习语中还可译成“先…（然）后；先…再” 。如： Before I go to the cinema, I must finish my homework. 我必须在去看电影之前做完作业。 We had sailed for two days before we saw land. 我们航行了两天才看见陆地。 It was not long before the Swiss rose up and drove the Austrian soldiers out of their country. 不久，瑞士人就举行起义，把奥地利 人赶出了他们的家园。
Wait till I call you. 等着我叫你。 否定句： She didn't arrive until 6 o'clock. 她直到 6 点才到。
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。
5. 比较 until 和 till 此两个连词意义相同。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。 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。 肯定句： I slept until midnight. 我一直睡到半夜时醒了。
You sound as though/if you ’ve caught a cold.你的声音听起来好像得了感冒。
Even though/if we achieve great successes in our work, we should not be conceited. 即使我们在工作中取得了很大成绩， 我们也不 该自满。
直到我开始工作，我才认识到了我已蹉跎了几多岁月。
2). It is not until …t hat … 强调句
It was not until I began to work that I realized how much time I had wasted. 6. though 的用法 ① though conj. “虽然；尽管” （不与 but 连用，但可以跟 yet, still 连用）；表示 “然而”时是副词（在句尾） ，如：
why 的问句。例如：
Biblioteka Baidu
I married her, not because she was rich, but because she was good –natured, clever and beautiful. Since you don't understand, I will explain it again.
Child as he is, he knows how to please the others. 2) be＋主语＋ or 连接的两个表语。这个句型相当于 whether…or…引导的让步从句。
让步状语
(al)though, as, even if, however, whatever, no matter
…, whe等ther … or
结果状语
so that, so … that, such … that
目的状语
in case, for fear that, so
方式状语
as, just as, as if(though)
