状语从句用法详解

副词子句用法详细内容提要：一、时间状语从句二、位置副词子句三、副词子句四、学位副词子句五、原因状语从句六、结果状语从句七、目的状语从句八、条件状语从句九、让步状语从句x，比较副词子句一、时间状语从句：1，时间副词子句通常是after，before，as，once，till，until，(ever) since，when，whenever，while，now()例如：Now (that) youve grown up，you must stop this childish behaviour。whatenever wemet with difficulties，they came to help e and see us whenever you have time。people do not know the value of health till they lose it。2、immediately、directly、instantly等一些词在用于as soon as的意思时，还可以推导以下时间状语从句的条款：I got in touch with him immediately I received his letter。my sister came directly she got my message。the machine will start instantly you press the button。I ll telephone you directly I hear the news。will you look for it immediately you get there？3.the (very) moment (=as soon as)、the minute (=as soon as)、the instant (=as soon as)、the day、the dayI ll tell you about it the moment you come。I started the instant I heard the report。the instant she saw him she knew he was her brother .Every time I catch a cold，I have pain in my back。I m going to see him next time he comes to Shenzhen .he left Europe the year world warbroke out。he had impressed me that way the first time I met him。I started the very moment I got your letter。I ll tell him the minute(that)he gets here。No sooner.than/hardly.when/scarcely.when/barely.一些相关的从属连接语(如when等)也可以诱导时间状语从句的条款。如果把nosooner，hardly，scarcely，barely放在句子开头，那部分的和必须重新安装，如下所示。shehad no sooner heard the news than she fainted .=no sooner had she heard the news than she fainted。they had hardly started to work when the troublesbegan。=hardly had they started to work when the troublesbegan。he had scarcely entered the room when the phone rang .=scarcely had he entered the room when the phone rang。二、位置状语从句：1，位置副词子句一般用where，wherever引导。We will stay where you stay。(where=in the place in whichWhere在连接主子句和子句的同时，在子句中修饰副词stay。)，以获取详细信息I found my books where I left them。Whaterever he happens to be，John can make himself at home。he will work wherever the people need him。let me go wherever(=to anyplace to which)they like(to go)。2，有时，由-where组成的复合词也可以推导出以下位置副词子句：Everywhere they went，they were kindly received/warmly welcomed。we ll go anywhere the party directs us。三、状语从句：1、方法副词子句一般由as、as if、as though引导。you must do the exercises as I show you。please do exactly as your doctor says。it looks as if it might snow/is going to snow。he acted as if/though nothing happened。He walked as if he was/were drunk。Mary was be having as though shehaden t grown up。2、非正式文体或口语中也可能导致the way(that)(=as=in the way in which)，how，like等：Jean doesnt do it the way I do .she is doing her work the way I like it done .You can do the job how you like。the landlord was watching him like(=just as)a catwatches a mouse。Do you make bread like you make cakes？使用类似于以下内容的连接词补充说明：1)。Conjunction (informal)(非正式):in the same way thatAs相同的.相同的people who change countries like they change clothes。改变国籍和换衣服是同一个人。2)as though；As if就像I felt like Id been kicked by a camel。好像被骆驼甩了。四、学位副词子句：程度副词子句是to such an extent that./to such a degree that.to the degree/extent that，in so far as(在的范围内)。例如：the temperature rose to such an extent that the firemen had to leave the burning building .the temperature lowered to such a degree that the water frozze。试验比较：the temperature rose so high that the firemen had to leave the burning building .the temperature lowered so much that the water froz。看上面的例句，程度副词子句通常表示达到一定程度时的结果，因此程度副词子句和结果副词子句有意义上的相通之处。at that time politicians were not known to the degree that they are today .那时政治家们并不像今天那么知名。Ill help you in so far as I can。我会尽我所能帮你。五、原因状语从句：1、引导原因状语从句的最常见的连词是because，since，as，诱导从句可以放在咒语前后。其中，because是最强的，since是其次，as是其次。 because通常表示说话的人认为说话的人不知道为什么或为什么，整节经文强调的原因并不取决于周口所表达的结果。回答Why提出的问题时，because只能使用；强调句型也只能用becksco子句，不能用since，as等。Because I cant see very well，I have to sit near the front。it was because he was ill that he didn t go with us。it was because he was ill that he didn t come。since和as引出的句子集中在主要句子的内容上。原因或原因看起来说话者很明显，或者已经熟悉顺从者。since和as只是次要说明，不是强调原因。例如：As he is working hard，he is likey to succed。Since he cant answer the question，youd better ask someone else。As/since he was not at home，I spoke to his brother。Since you in sist，I will recon sider the matter。As he was in a hurry，he left his bag at home。 for是并行连接词。这个连词可以把句子后置。表示因果关系时，可以将其替换为because。但是，在用于说明或推断主句的内容时，不能用because代替，如下所示：He couldnt have seen me，because/for I was not here。The ground is wet，for/because it rained last night。It rained last night，for the ground is wet this morning。您可以在because之前添加simply、only、just等强调词。you should n t get angry just because some people speak ill of you。2、复合连词还可以诱导以下原因状语从句。now (that)、seeing (that)、consiring (that)、for the reason that、by reason that、for fear that、thatNow (that) (=since) you mention it，I do remember。Now (that) he is absent，you ll have to do the work by your self。Now (=since) the rain has stopped，lets start。seeing(that)all the guests have arrived，lets have dinner。she didn t go for fear that she would get lost .He has done very
