例如： 　　Where there is no rain, farming is difficult or impossible.在没有雨水的地方，耕作是困难的，或根本不可能的句型2：Anywhere/ wherever＋地点从句，＋主句 　　【注意】anywhere本身是个副词，但是，常可以引导从句，相当于连词，意思相似于wherever, anywhere引导的从句可位于主句之前，也可以位于主句之后 而wherever本身就是个连词，表示“在何处，无论何处”例如： 　　Wherever the sea is , you will find seamen.有海就有海员原因状语从句: 常用引导词：because=in that, since=now that(既然), as, for(补充说明) 特殊引导词：seeing that, now that, in that, considering that, given that（考虑到）.目的状语从句：常用引导词：so that, in order that 　　特殊引导词：lest, in case, for fear that（唯恐生怕），in the hope that（带着..希望）, for the purpose that（带着..目的）, to the end that结果状语从句：常用引导词：so … that, such … that, 　　特殊引导词：such that, to the degree that, to the extent that, to such a degree that,条件状语从句：常用引导词：if, unless, 　　特殊引导词：as/so long as（只要）, only if, providing/provided that（倘若）, supposing that（倘若）, in case that（以防）, on condition that让步状语从句：　常用引导词：though, although, even if, even though（即使） 　　特殊引导词： as(用在让步状语从句中必须要倒装)，while ( 一般用在句首 )，no matter …， in spite of the fact that, while, whatever, whoever, wherever, whenever, however, whichever,as if=as though（仿佛） 比较状语从句：常用引导词：as(同级比较), than(不同程度的比较) 　　特殊引导词：the more … the more … ; just as …， so…; A is to B what /as X is to Y（A对B来说，像X对Y一样）; no … more than; not A so much as B方式状语从句：常用引导词：as, as if, how 　　特殊引导词：the way10. 状语从句的简化　　♠状语从句的省略 　　状语从句同时具备下列两个条件:①主句和从句的主语一致，或从句主语为it；②从句主要动词是be的某种形式。

从句中的主语和be动词常可省略例如： 　　When ( the museum is ) completed , the museum will be open to the public next year . 　　He’ll go to the seaside for his holiday if (it is ) possible. 　　另外，比较状语从句经常省略例如： 　　I’m taller than he (is tall ). 　　The higher the temperature (is), the greater the pressure (is ). 　　就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化"状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高因此,有必要对其进行全面、透彻的了解 　　状语从句的"简化"现象常存在于以下五种状语从句中:①由if, unless等引导的条件状语从句;②由although, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状语从句;⑤由as, than等引导的比较状语从句。

下面针对这五种情形作一归纳 　　(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉例如: 　　If (it is) possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境 　　You must attend the meeting unless (it is) inconvenient to you.除非情况对你来说不方便,否则你必须出席这次会议 　　(2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉常用于以下几种情形: a.连词+形容词　　As (he was) young, he learned how to ride a bike.他小时候就学会了骑自行车 　　Whenever (she is) free, she often goes shopping.她有空就去逛商店 　　Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲 b.连词+名词　　While (he was) a young boy, he was always ready to help others.他在孩提时代就乐于助人。

He wouldn't solve the problem even if (he were) to take charge.即使他来负责,他也解决不了这个问题 f. 连词+介词短语　　　　注意:当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表达例如: 　　When the meeting was over, all the people went out of the meeting-room.当会议结束时,人们都走出了会议室The meeting over,　She looked anxious as though (she was) in trouble.她看上去很焦急,好像遇到了麻烦。
