状语从句——条件状语从句学案
学习过程
一、复习预习
状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。
二、知识讲解
【考查点1】
引导条件状语从句最常用的连词是if，常见的if条件状语从句表示在某条件下，某事很可能发生，条件是可能存在的，主句中某种情况发生的概率也是很高的。如：
If you ask him，he will help you．如果你请他帮忙，他会帮你的。
If you fail in the exam，you will let him down．如果你考试不及格，你会让他失望的。
If you have finished the homework，you can go home．如果你作业做完了就可以回家了。
另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设。从句多用一般过去时或过去完成时，表示对现在或过去的一种假设。如：
If I were you，I would invite him to the party．如果我是你，我会邀请他参加聚会。
I would have arrived much earlier if I had not been caught in the traffic．要不是交通堵塞，我本会来得早一些。
【考查点2】
另外要注意if 条件句的时态搭配
1．if从句用一般现在时，主句用一般将来时
If he runs he’ll get there in time. 如果他用跑的，他就会及时赶到那儿。
The cat will scratch you if you pull her tail. 如果你拉猫的尾巴，它就会抓你。
2．if从句用一般现在时，主句用may/might/can
If the fog gets thicker the plane may/might be diverted. 如果雾在大一些，飞机可能就会改在别的机场降落。
If it stops snowing we can go out. 如果雪停了，我们就可以出去。
3．if从句用一般现在时，主句用must/should
If you want to lose weight you must/should eat less bread. 如果你想减肥，你必须少吃面包。
4．if从句用一般现在时，主句用一般现在时
If you heat ice it turns to water. (也可用will turn)如果把冰加热，它就会化成水。
5．if从句用现在进行时，主句用一般将来时
If you are looking for Peter you’ll find him upstairs. 如果你是在找彼得，上楼就会找到他。
6．if从句用现在完成时，主句用一般将来时
If you have finished dinner I’ll ask the waiter for the bill. 如果你吃完了，我就叫服务生来算账
注意：
学习" if " 引导的条件状语从句的用法,现在总结一下:
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.
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

状语从句——条件状语从句学案
学习过程 一、复习预习 状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。 二、知识讲解 【考查点1】 引导条件状语从句最常用的连词是if，常见的if条件状语从句表示在某条件下，某事很可能发生，条件是可能存在的，主句中某种情况发生的概率也是很高的。如： If you ask him，he will help you．如果你请他帮忙，他会帮你的。 If you fail in the exam，you will let him down．如果你考试不及格，你会让他失望的。 If you have finished the homework，you can go home．如果你作业做完了就可以回家了。
另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设。从句多用一般过去时或过去完成时，表示对现在或过去的一种假设。如： If I were you，I would invite him to the party．如果我是你，我会邀请他参加聚会。 I would have arrived much earlier if I had not been caught in the traffic．要不是交通堵塞，我本会来得早一些。 【考查点2】 另外要注意if 条件句的时态搭配 1．if从句用一般现在时，主句用一般将来时 If he runs he’ll get there in time. 如果他用跑的，他就会及时赶到那儿。 The cat will scratch you if you pull her tail. 如果你拉猫的尾巴，它就会抓你。 2．if从句用一般现在时，主句用may/might/can If the fog gets thicker the plane may/might be diverted. 如果雾在大一些，飞机可能就会改在别的机场降落。 If it stops snowing we can go out. 如果雪停了，我们就可以出去。 3．if从句用一般现在时，主句用must/should If you want to lose weight you must/should eat less bread. 如果你想减肥，你必须少吃面包。 4．if从句用一般现在时，主句用一般现在时 If you heat ice it turns to water. (也可用will turn)如果把冰加热，它就会化成水。 5．if从句用现在进行时，主句用一般将来时 If you are looking for Peter you’ll find him upstairs. 如果你是在找彼得，上楼就会找到他。

专题10 状语从句 状语从句包括时间状语从句、地点状语从句、条件状语从句、让步状语从句、原因状语从句、目的状语从句和结果状语从句。状语从句的考查主要集中在连接词的掌握上，尤其要重视as, until, before, since, when, in case等连词的各种语义功能和语法功能。其考点主要包括： 1．考查状语从句的连接词。要掌握每个连词的含义及其用法，还有它们之间的一些区别。如：时间状语从句的连词有while, when，as，as soon as，until，not…until，before, after，since等；条件状语从句的连词有 if，unless, in case, on condition that, provided (that), supposing, suppose (that)等；结果状语从句的连词有so…that(如此……以至于)，such…that(如此……以至于)等。 2．考查固定搭配和习惯用法的连接词。如：no sooner…than/hardly…when(一……就……); the moment/minute，directly等的连词功能。 3．考查不同性质的连词在不同的语境中所表现的不同意义，如as既能引导时间状语从句，又能引导原因状语从句和让步状语从句； where引导地点状语从句和定语从句等。 4．考查状语从句的时态。主要考查时间、条件、让步状语从句用一般现在时表将来，以及一般过去时代替过去将来时的用法。 5．考查状语从句的省略。在时间、原因、条件、方式、让步等状语从句中，常常省略相同的主语或作主语的代词it以及be动词，保留现在分词、过去分词、介词短语、不定式等成分。如果从句中有“it is ＋形容词”，也可以省略it is。 连词的考查主要集中在并列句和各种复合句中，主要考查连词的意义辨析。如：and, but, or或while 以及其他连接名词性从句、定语从句和状语从句的连接词、关联词。 一、时间状语从句 (一)when，while与as引导的时间状语从句 1．when，while与as引导时间状语从句的区别 连词谓语动词用法点津 when 延续性动词 非延续性动词 从句的动作和主句的动作可以同时发生，也可以先后发生 while 延续性动词从句的动作与主句的动作同时发生
