地点状语从句 地点状语从句表示地点、方位，这类从句通常由where引导。 用法 例如： Where there is a will, there is a way. 有志者，事竟成。 They will go where they are happy. 他们想到他们觉得快乐的地方去。 连词含义说明 where在……地方通常表示一个确定的wherever无论什么地方表示“任何地方”anywhere无论何处 everywhere到处 (1)地点状语从句由where，wherever，引导， 如： We must camp where we can get water. 我们必须在能找到水的地方露营。 (2)地点状语从句与定语从句的区别: 在于分句在句中作什么成分。作状语，则是状语从句；作定语修饰名词，则是定语从句where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。 如： Go back where you came from.(where引导地点状语从句） 你从何处来到何处去。 Go back to the village where you came from.(where引导定语从句，修饰village) 回到你来的那个村子里去。 (1)We went home, where we had dinner.此句是where引导的"非限制性"定语从句,这里"where"= at home(先行词是home)从句还原" we had dinner at home"全句译：我们回到家，在家里吃了顿饭. (2)I walk into the canteen where students are eating此句也是where 引导的定语从句，与上句不同之处在于此句是一个"限制性"定语从句.全句译：我走进了这个同学们都在吃饭的食堂。（限定说明了是一个什么样的食堂) (3)地点状语从句与定语从句其本身属性就不同：地点状语从句相当于大的副词;定语从句相当于大的形容词,副词是用来修饰动词的,
中考英语总复习状语从句经典例题含答案解析 一、初中英语状语从句 1．Mr. White tells us the calls meeting will be cancelled if no agreement _________ tomorrow. A．is reached B．will be reached C．is going to be reached D．has been reached 【答案】A 【解析】 【详解】 句意：怀特先生告诉我们，如果明天没有达成协议，电话会议将取消。本题是含有if引导的条件状语从句的复合句。在 if 引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。选项的位置在 if 引导的条件状语从句中，要用一般现在时态，B C选项是将来时态不符合题意要排除。D选项是现在完成时态不符合题意要排除。Reach an agreement达成协议固定短语搭配。agreement is reached协议做主语要用被动语态，故选A。 【点睛】 if 条件句不一般,几个要点记心间; 条件句,放在前,逗号要放句中间。 条件句表可能，主句多用将来时； 条件句表事实，主句常用现在时。 在 if 引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。如： We can walk there if we can't find a bus. If it rains tomorrow, we will not go to the zoo. What will you do if you find a panda in danger. 如果 if 条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。如： If bears are in danger, they attack people. 注意： 在 if 引导的条件状语从句中，if 和条件句位置灵活，可直接放在主句后面，若 if 条件句放句首，从句后面要加逗号，和主句隔开。还要注意前后时态一致原则。 2．—I’m going to the post office. —________you are there, can you get me some stamps? A．When B．While C．Because D．If 【答案】B 【解析】 试题分析：A. As 一边…一边，作为 B. While当…时候 C. Because 因为 D. lf假如；句意：我将要去邮局。你去那里的时候，能不能给我带一些邮票呢？故选B 考点：连词 点评：连词在中考中涉及到的很多，尤其在宾语从句、状语从句、定语从句中连词是必考

状语从句解题例析 高考中涉及状语从句的题目非常多，几乎覆盖了所有的状语从句类型，其中多数需要对题干信息进行加工才能得出正确答案。从状语从句的特点来看，正确理解连接词的含义、把握句子的整体意义是答题的关键。笔者从连接词入手，结合高考试题，对状语从句进行分析，希望能提高同学们的解题能力。 一、状语从句中的连接词 状语从句分时间、地点、原因、条件、目的、结果、方式、比较、让步等9类。 时间状语从句的连接词有：when,while,as,before,after,since,till,until,as soon as,the moment,me minute,im-mediately(一……就)，instantly(一……就)，every time,each time,the firsttime,any time等； 地点状语从句的连接词有：where,wherever等； 原因状语从句的连接词有：becau-se,as,since(既然)，now that等； 条件状语从句的连接词有：un-less,if,once(一旦)，as long as(只要)，so long as(只要)，on condition that(条件是)，provided that(如果)等； 目的状语从句的连接词有：so that,in order that,in case(万一)，for fear that(以免)，lest(以免)等； 结果状语从句的连接词有：so that,so…that,such…that等； 方式状语从句的连接词有：as,asif,as though等； 比较状语从句的连接词有：as…as,so…as,than等； 让步状语从句的连接词有：althoug,though,as(尽管)，even if,even though,whoever,whatever,whenver,wherever,no matter what/who/when/where/how等。 二、解题例析 1．全面了解状语从句的知识，熟悉每个连接词的语义和用法，同时了解个别连接词的多种意思。 (1)as,since等连接词的用法比较灵活，既可以引导时间状语从句，又可以引导原因状语从句。 例1 “Y ou can't have thi s foot-ball back——you promise not to kick it at my cat again,”the old man said firmly. A．because B．since C．when D．where 解析：本题的主句意为“你不能把足球拿回去”，从句意为“你答应过不再用足球踢我的猫”。根据其逻辑，从句为原因状语从句，答案应为B(since在此处意为“既然”，而不是“自从”)。
