英语语法：状语从句八大类型的区分以及知识点讲解NO.1 副词作状语(1)句子副词：句子副词用于修饰句子(而不是修饰某个单个的词)，反映说话人的观点和看法。

如actually, apparently, certainly, clearly,definitely, evidently, fortunately, frankly, honestly, luckily, obviously, perhaps, possibly, probably, surely, undoubtedly, unexpectedly 等。

作用以及位置：句子副词通常位于句首(或分句句首)。

Eg:Obviously he can't tell the difference between them. 显然他无法区别两者的不同。

I arrived late but luckily the meeting had been delayed. 我迟到了，幸而会议推迟了。

但有些句子副词也可以出现句中。

eg：He smiled nastily. He evidently knew something I didn't. 他发出狞笑，他显然知道一些我所不知道的事。

有的句子也可用作其他种类的副词，不过这往往会导致位置和语义的变化：Clearly he didn't say so. 显然他没有这样说。

(句子副词)He didn't say so clearly. 他说得没有那么清楚。

(方式副词)(2)起连词作用的副词连接副词就是连接词，如besides，meanwhile，then, therefore, thus, However,Otherwise, so, yet 等。

作用以及位置：常放在两个句子中间，前面为逗号，后面放连接词，从句之前。

注意：so 也可放在形容词之前做修饰，yet 可放句尾或从句之前。

高中英语语法系统讲解之十一状语从句状语从句在句中作状语，修饰主句中的动词、形容词或副词等，有时修饰整个主句。

状语从句放在主句之前时，常用逗号分开；放在主句之后，一般不用逗号。

状语从句按其意义和作用分为时间、条件、原因、让步、目的、结果、方式、比较、地点等9种。

1. 时间状语从句时间状语从句可放在句首、句中或句尾。

常用when，while，as，after，before，since，until，once，as soon as，the minute / moment“一……就……”，hardly … when，no sooner … than“刚……就……”等连接词引导。

○1连词when，while，as都表示“当……的时候”，但是when引导的从句的动作和主句的动作可以同时发生，也可以先后发生；用as，while时则强调主句和从句的动作同时发生。

如While I was reading, he came in.As he walked along the street, he sang happily.但当从句表示“随时间推移”时，只能用连词as，不能用when或while。

如As time goes on, I like to speak English more and more.○2从属连词as soon as，immediately，directly，the moment，the minute，no sooner … than …， hardly / scarcely … when …，once引导的从句都表示从句的动作一发生，主句的动作随即就发生，意为“一……就……”，从句中用一般时态代替将来时态。

如Once you remember it, you’ll never forget it.The moment I heard the voice, I knew father was coming.No sooner had we arrived at the station than the train left.温馨提示：as soon as，the moment引导的从句表示“一……就……”；no sooner … than …，hardly … when引导的从句表示“刚……就……”。

一，状语从句状语从句在主从复合句中修饰主句中的动词、形容词或副词等，起副词的作用。

状语从句由从属连词引导，从属连词在从句中不担任任何句子成分。

状语从句可位于主句之前，也可位于主句之后。

位于主句之前，一般要加逗号与主句分开；位于句末则不需要。

状语从句根据它所表达的意思可分为时间、地点、原因、目的、结果、比较，让步、方式和条件状语从句等类。

（一），时间状语从句引导时间状语从句的从属连词有：when, while, as soon as, before, after, since , till, until 等【注】1，until (till) 直到，在用until 表达时间状语的句子中，主句中的动词是要十分小心去选择。

如动词是持续性动词，它要用肯定句，如：I studied hard until 12 o'clock last night. 如果动词是瞬间截止性动词，则要用否定句，即，not---until “直到…才”。

如：He didn't go to bed until his mother came back.They didn’t stop until they finished t he work .2，时间状语从句中的谓语动词不能用,将来时，终能用一般现在时表示一般将来时，即“主将从现”原则。

如，When he comes, I’ll tell him about it.I will call you as soon as I arrive in Beijing. 我到北京就将给你打电话(二)，条件状语从句通常由从属连词if，unless等引导【注】1，条件状语从句与时间状语从句一样，从句中不能用将来时态，要用一般现在时态表示一般将来时态，也符合“主将从现”原则。

如，If it snows tomorrow, we will build a snowman.If it rains, they won't go to the park on SundayI won’t go to his party unless I am invited .,2，要区别是条件、时间状语从句还是宾语从句，因为在宾语从句中该用什么时态用什么时态，如：I want to know if he will come here tomorrowI want to know if it will rain tomorrow. If it doesn’t rain, I will go hiking.I don’t know when he will come, When he comes, I’ll tell him about it.（三），让步状语从句通常由从属连词though（although）（虽然，尽管），even if（even though）（即使）等引导注：翻译是后半句带有转折的意味，但不能由but连接。
