1、十一连词和状语从句十一连词和状语从句 状语从句是高考的热点之一。状语从句又称为副词性从句，包括时间状语从句、条件状语从句、原因状语从句、让步状语从句、目的状语从句、结果状语从句、方式状语从句等。要求考生要充分理解和掌握状语从句的用法。考查的重点集中在时间状语从句、条件状语从句、让步状语从句和目的状语从句。试题的设置呈现综合性和交叉性，往往与定语从句和名词性从句结合起来考查，尤其对于不同性质的连词，要注意其在不同的语境中所表示的不同意义，正确地把握题干的语境意义和上下文的逻辑关系，是做好状语从句试题的关键所在。 We were about to set off on our way, when

2、it suddenly began to rain. 我们正要动身，这时突然开始下雨了。 此外还表示原因“既然”，如： It was foolish of you to take a text when you could easily walk there in five minutes. 既然你能够五分钟内轻易地步行去那儿，你乘出租车去真是太愚蠢了。 (5)while作为并列连词，意为“而，却”，表示对比。 He likes pop music, while I am food of folk music. 他喜欢流行音乐，而我喜欢民间音乐。 (6)如果主句表示的是短暂动作，而从句用延续性

3、动词的进行时态表示在一段时间内正在进行的动作时，when与while可互换使用。如： When/While/As I was walking down the street, I came across an old friend of mine. 我沿着街道走的时候，遇到了一位老朋友。 2as soon as, immediately, the moment, the m i n u t e , n o s o o n e r . . . t h a n . . . ，hardly/scarcely.when. once(一且就) 这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即

4、就发生，常译为“一就”，从句中用一般时态代替将来时态，如： Once you remember it, youll never forget it. 一旦你记住了它，将永远不会忘记。 The moment I heard the voice, I knew father was coming. 我一听到声音，就知道父亲来了。 No sooner had we arrived at the station than the train left. 我们一到车站，火车就走了。 The boy burst into tears immediately he saw his mother. 一看到他的

5、母亲，男孩突然大哭。 注 意 ： n o s o o n e r . . . t h a n ；hardly/scarcely.when.这一结构的时态搭配：no sooner与hardly/scarcely引导的主句谓语动词应用过去完成时，而than与when的从句中谓语动词应用一般过去时。此外，当把no sooner和hardly/scarcely提到句首时，应用倒装程序。如： I had hardly got home when it began to rain. Hardly had I got home when it began to rain. 我一到家，就开始下雨了。 3til

6、l, until和not.until (1)肯定句：主句谓语动词必须是延续性动词，主句、从句都为肯定式，意为“某动作一直延续到某点时间才停止”。如： He remained there until she arrived. 他一直留到她来。 You may stay here until the rain stops. 你可以在这里呆到雨停。 (2)否定句：主句谓语动词必须是非延续性动词，从句为肯定式，意为“某动作直到某时间才开始”。 如：He wont go to bed till (until) she returns. 直到她回来，他才睡。 (3)till不可以置于句首，而until可以

7、。如： Until you told me I had no idea of it. 直到你告诉我，我才知道这件事。 (4)not.until 句型中的强调和倒装说法 It was not until you told me that I had any idea of it.(强调句型) Not until you tole me did I have any idea of it.(not until 置于句首主句要倒装) 4before和since 若表达“还未就”“不到就”“才”“趁还没来得及”时，需用连词before。 如：We had sailed four days and fo

8、ur nights before we saw land. 我们航行了四天四夜才看到陆地。 We hadnt run a mile before he felt tired. 我们跑了还不到一英里他就累了。 Please write it down before you forget it. 趁你现在没忘把它记下来。 Before I could get in a word, he had measured me. 我还没来得及插话他就给我量好了尺寸。 before从句中谓语不用否定式，又如： Before they reached the station, the train had gon

10、我往家里写了四封信。 She has been working in this factory since she left school. 她毕业后在这工厂工作四年了。 (2)在It is时间since从句句型中，时间的计算一律从since从句的动作完成或状态结束时算起，如： It is three years since the war broke out. 战争爆发以来，有三年了。 It is three years since she was in our class. 她离开我们班有三年了。 It is three years since he lived here. 他不在这儿住已

11、有三年了。 It is three years since I (have) smoked a cigar.
