1、状语从句的分类总结（三）7 让步状语从句 though, although注意： 当有 though, although 时，后面的从句不能有 but，但是 though 和 yet 可连用Although its raining, they are still working in the field. 虽然在下雨，但他们仍在地里干活。He is very old, but he still works very hard. 虽然他很老，但仍然努力地工作。Though the sore be healed, yet a scar may remain.伤口虽愈合，但伤疤留下了。 （谚语）典型
2、例题 1） _she is young, she knows quite a lot. A. When B. However C. Although D. Unless 答案：C。意为虽然她很年轻，却知道许多。2) as, though 引导的倒装句as / though 引导的让步从句必须表语或状语提前（形容词、副词、分词、实义动词提前） 。Child as /though he was, he knew what was the right thing to do.= Though he was a small child, he knew what was the right thing
3、 to do.注意： a. 句首名词不能带任何冠词。b. 句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随 实义动词一起放在主语之前。Try hard as he will, he never seems able to do the work satisfactorily.= Though he tries hard, he never seems虽然他尽了努力，但他的工作总做的不尽人意。3) ever if, even though. 即使Well make a trip even though the weather is bad.4) whetheror- 不管都Wh
4、ether you believe it or not, it is true.5) “no matter +疑问词“ 或“疑问词+后缀 ever“ No matter what happened, he would not mind.Whatever happened, he would not mind.替换：no matter what = whateverno matter who = whoeverno matter when = wheneverno matter where = whereverno matter which = whicheverno matter how =
5、however注意：no matter 不能引导主语从句和宾语从句。（错）No matter what you say is of no use now.（对）Whatever you say is of no use now.你现在说什么也没用了。(Whatever you say 是主语从句)（错）Prisoners have to eat no matter what theyre given, （对）Prisoners have to eat whatever theyre given. 囚犯们只能给什么吃什么。 8 比较 while, when, as 1）as, when 引导短暂
6、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 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。9 比较 until 和 till 此两个连词意义相同。
7、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。Wait till I call you. 等着我叫你。（在肯定句中可用 before 代替 Lets get in the wheat before the sun sets.）否定句：She didnt arrive until 6 oclock.她直到 6 点才到。Dont get off the bus
8、 until it has stopped. 公共汽车停稳后再下车。I didnt manage to do it until you had explained how. 直到你教我后，我才会做。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
9、。 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. 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 that 10 表示“一就“的结构 hardly/scarcelywhen/before, no so
10、onerthan 和 as soon as 都可以表示“一就“的意 思，例：I had hardly / scarcely got home when it began to rain.I had no sooner got home than it began to rain.As soon as I got home, it began to rain.注意：如果 hardly, scarcely 或 no sooner 置于句首，句子必须用倒装结构：Hardly / Scarcely had I got home when it began to rain.No sooner had I got home than it began to rain.
