1、初一英语暑假专题：状语从句湘教版【本讲教育信息 】一 . 教学内容：暑假专题：状语从句二 . 重、难点内容：状语从句的分类及讲解三 . 具体内容：1. 地点状语从句地点状语从句通常由where, wherever 引导。例如：Where I live there are plenty of trees.我住的地方树很多。Wherever I am I will be thinking of you.不管我在哪里我都会想到你。2 方式状语从句方式状语从句通常由 as, （just ） asso, as if, as though 引导。1） as, （just ）结构中位于句首，这时文体。例如：
2、as so引导的方式状语从句通常位于主句后，但在（ just） as so as 从句带有比喻的含义，意思是“正如” ，“就像”，多用于正式Always do to the others as you would be done by.你希望人家怎样待你，你就要怎样待人。As water is to fish, so air is to man.我们离不开空气，犹如鱼儿离不开水。Just as we sweep our rooms, so we should sweep backward ideas from our minds.正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。2） as
3、if, as though两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作“仿佛似的” ，“好像似的” 。例如：They completely ignore （不顾，不理，忽视）these facts as if（ as though） they never existed.他们完全忽略了这些事实，就仿佛它们不存在似的。（与事实相反，谓语用虚拟语气。）He looks as if （ as though） he had been hit by lighting.他那样子就像被雷击了似的。（与事实相反，谓语用虚
4、拟语气。）It looks as if the weather may pick up very soon.看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。）说明： as if / as though 也可以引导一个分词短语、不定式短语或无动词短语。例如：He stared at me as if seeing me for first time.他目不转睛地看着我，就像第一次看见我似的。He cleared his throat as if to say something.他清了清嗓子，像要说什么似的。The waves dashed on the rocks as if in
5、 anger. 波涛冲击着岩石，好像很愤怒。3. 原因状语从句比较 because, since, as和 for：1） because 语势最强，用来说明人所不知的原因，回答why 提出的问题。当原因是显而易见的或已为人们所知，就用as 或 since。例如：I didn t go, because I was afraid我.不去是因为我怕。Since /As the weather is so bad, we have to delay our journey.天气那么糟，旅行推迟了。2）由 because引导的从句如果放在句末，且前面有逗号，则可以用不是说明直接原因，而是多种情况加以推
6、断，就只能用for。例如：for来代替。但如果He is absent today, because / for he is ill. 他今天缺席，因为他病了。He must be ill, for he is absent today.他一定病了，所以今天缺席。4. 目的状语从句表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case 等词引导。例如：You must speak louder so that /in order that you can be heard by all. 你必须大点声， 别人
7、就能听见了。He wrote the name down for fear that （ lest） he should forget it. 他写下了这个名字以免以后忘记。Better take more clothes in case the weather is cold. 最好多穿点衣服，以防天变冷。5. 结果状语从句结果状语从句常由so that 或 such that 引导。 so that 与 such that 之间可以转换。例如：The boy is so young that he cant go to school这男孩.年龄太小，不能上学。He is such a yo
8、ung boy that he cant go to school6. 条件状语从句连接词主要有if, unless, as/so long as, on condition that等。 if引导的条件句有真实条件句和非真实条件句两种。非真实条件句已在虚拟语气中阐述。unless = if not.例如：Let s go out for a walk unless you are too tired. 如果不太累，我们去散散步。If you are not too tired, lets go out for a walk.典型例题You will be late _ you leave i
9、mmediately.A. unlessB. untilC. ifD. or答案A 。句意：除非你立即走，否则你就会迟到的。可转化为Ifyou dont leaveimmediately, you will be late 。B、D 句意不对， or 表转折， 句子应为You leave immediately oryou will be late.7. 让步状语从句1） though, although 引导的让步状语从句，后面的从句不能有but，但是though和 yet可连用。例如：Although it s raining, they are still working in the
10、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.虽然他很老了，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）2） as, though 引导的让步状语从句中表语或状语必须提前（形容词、副词、分词、实义动词提前） 。例如：Child as /though he was, he knew what was the right thing to do. 虽然是个小孩，该做什么不做什么，他全知道。3） even
11、if, even though即使。例如：We ll make a trip even though the weather is bad. 即使天气不好，我们也要去远足。4） whether or不管都。例如：Whether you believe it or not, it is true.信不信由你，这确实是真的。5）“ no matter +疑问词”或“疑问词 +后缀 ever”。例如：No matter what happened, he would not mind. =Whatever happened, he would not mind. 不管发生什么，他不在意。替换： no
12、 matter what = whateverno matter who = whoeverno matter when = wheneverno matter where = whereverno matter which = whicheverno matter how = 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） Pri
13、soners have to eat no matter what they（对） Prisoners have to eat whatever they8. 比较 while, when, asre given.re囚given犯们只.能给什么吃什么。1） as, when 引导短暂性动作的动词。例如：Just as / Just when / When I stopped my car, a man came up to me. 我一刹车， 有一个人向我走来。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 。例如：When you hav
14、e finished your work, you may have a rest.干完活后，你可以休息一下。3）从句表示“随时间推移”连词能用as，不用 when 或 while 。例如：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。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。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 mi
15、dnight.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。例如 Let s get in the wheat before the sun sets）.否定句： She didn t arrive until 6 o她clock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。区别： 1） until 可用于句首，而til
16、l 通常不用于句首。例如：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。例如： Until when are you staying? 你呆到什么时候？ Until next Monday. 呆到下周一。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。例如：Not until the early years of the 19th century did man know what heat i
17、s.直到 19 世纪初，人类才知道热为何物。Not until I began to work did I realize how much time I had wasted.直到工作，才认识到我已蹉跎了几多岁月。2） It is not until。that例如：It was not until I began to work that I realized how much time I had wasted.10. 表示“一就”的结构hardly/scarcely when/before, no sooner than 和 as soon as都可以表示“一就” 的意思。例如：I ha
18、d hardly / scarcely got home when it began to rain.刚回家，就下起雨来了。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。例如：Hardly / Scarcely had I got home when it began to rain.No sooner had I got home than it began to ra
