它可以用来修饰主语中的动词.形容词.副词等。 根据它表达的意思，状语从句可以分为时间状语从句，地点状语从句，条件状语从句，比较状语从句，目的状语从句，结果状语从句和让步状语从句等。 二if引导的条件状语从句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 willhelp you如果你请他帮忙，他会帮你的。 If youfail inthe exam，you will lethimdown如果你考试不及格，你会让他失望的。 If youhave finishedthe homework，you cangohome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 Iwere you，I wouldinvite himto theparty如果我是你，我会邀请他参加聚会。 I wouldhave arrivedmuch earlierif Ihad notbeen caughtinthetraffic要不是交通堵塞，我本会来得早一些。 if条件句的时态1主将从现（用法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。 ）The catwill scratchyou if you pullher tail.如果你拉猫的尾巴，它就会抓你。 If heruns,he will get therein time.如果他用跑的，他就会及时赶到那儿。 同义句Run and you willget therein time.=Run oryoullgetthere late.6If条件句的同义句祈使句，and/or+将来时态的陈述句。 Work hard,andyou will make great progress.=If youwork hard,youwill makegreatprogress.2.主现从也现（用法如果if条件句谈论的是重复发生或客观条件下必然发生的事件，if从句用一般现在时，主句也用一般现在时。 ）If youheat ice,it turnsto water.(也可用will turn)如果把冰加热，它就会化成水。 3.主情从现（用法如果从句谈论的事件有主观看法或情感色彩的时候，从句用含情态动词may/might/can/must/should句子表达。 ）If thefog getsthicker,the planemay/might bediverted.如果雾在大一些，飞机可能就会改在别的机场降落。 If itstops snowing,we cango out.如果雪停了，我们就可以出去。 If youwant tolose weight,you must/should eatless bread.如果你想减肥，你必须少吃面包。 4.如果主句是祈使句，那么从句通常要用一般现在时。 If youwanttohave achat,call meup.如果你想聊天，打我电话。 5if从句用现在进行时，主句用一般将来时If you are lookingfor Peteryoull findhim upstairs.如果你是在找彼得，上楼就会找到他。 6if从句用现在完成时，主句用一般将来时If youhave finisheddinner Ill askthe waiterfor thebill.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。 主句要是表情感，情态动词就上场。 If除了可以引导状语从句外还可以引导宾语从句，此时if意为“是否”。 例如I wonderthat if he will e tomorrow.If he es,I will go.我想知道他是否明天会过来，如果他来我就走。 三Unless引导的条件状语从句unless conj.除非,若不,除非在的时候（if.not.）You willfail toarrive therein timeunless youstart earlier.如果你不早点动身,你就不能及时赶到那儿。 Unless it rains,the gamewill beplayed.除非下雨,比赛将照常进行。 四.so/as long as conj.只要You mayborrow mybook aslongasyou keepit clean.只要你保持书的清洁，你就可以把我的书借去。 7条件状语从句的时态练习一请在正确答案下载划横线。 1.Daina(will go/go/goes)to Europeif she(will pass/pass/passes)the exams.2.If you(will heat/heat/heats)the
