1.Structure这里if所引导的是真实条件句(realconditional),

即所假设的条件有可能成为现实,表达假定所假设的条件实现时会出现的情况或会采取的行为。有时,我们可以使用并列结构的祈使句来表达这种类型的条件句。e.g.Ifyousetyouralarmclock,youwon’toversleep.如果你上闹钟,你就不会睡过头了。

Setyouralarmclock,andyouwon’toversleep.Ifyougivehimaninch,hewilltakeamile.他会得寸进尺。

Givehimaninch,andhewilltakeamile.Ifyoudon’tgivehimsomefood,hewillstarve.如果你不给他一点吃的,他就会饿死。

Givehimsomefood,or/elsehewillstarve.(1)条件状语从句通常由连词if引导,意为“如果、假如”,主句不能用begoingto表示将来,而应该用shall、will。

e.g.Ifyouleavenow,youarenevergoingtoregretit.(错误)

Ifyouleavenow,youwillneverregretit.(正确)(2)if“如果”,引导条件状语从句,主句用一般将来时，从句则用一般现在时，如：

Ifitrainstomorrow,Ishan’tclimbthehills.2.用法注意:

宾语从句中的if与条件状语从句if的区别。宾语从句中的if“是否”相当于whether,引导宾语从句,时态需根据语境确定。

Idon'tknowifitwillraintomorrow.我不知道明天是否会下雨。在if-分句中中用“will＋动词原形”并不单纯表示将来意义，这里的will是个表示“意愿”的情态动词,相当于bewillingto(愿意)。要注意这种带“will＋动词原形”的if-分句在某些场合是不可以随便用的,

比如我们可以说：Ifhegetsmyletterintime,he’llbeabletochangehisplans.

如果他及时收到我的信,他就能改变他的计划。却不可以说成：Ifhewillgetmyletterintime,he’llbeabletochangehisplans.另外,在if-分句中还可能使用“would＋动词原形”的结构，这种用法还是表示“意愿”,常用于表示客气的请求,这时主句动词既可以用will/shall＋动词原形,也可以用would/should/could/might＋动词原形。如：IfyouwouldtryItalianfood,youwouldlikeit.如果你愿意尝尝意大利食物,你会喜欢它的。Ifyouwouldreservetheseats,wewouldbesureofacomfortablejourney.如果你愿意订座,我们将肯定会有一个舒适的旅程。1.如果你不赶快走,你就会迟到。2.如果你爱你的父母,你应当帮他们做做家务。3.如果你更友善一些,你会教上很多好朋友。Ifyoudon’tgosoon,you’llbelate.Youshouldhelpdothehouseworkifyouloveyourparents.Youwillmakelotsoffriendsifyouaremorefriendly.PracticeDearSuMei,Idon’t______(know)whatto______(do)aboutgoingtoMike’sbirthdaypartytomorrownight.Myparents_____(think)IshouldstudyformyEnglishexamnextweek.IfI_____(go)totheparty,they_______(be)upset.Fillintheblankswiththecorrectformsoftheverbsinbrackets.knowdothinkgowillbe3aMike______(tell)ustowearniceclothes,butIdon’t________(have)any.IfI_______(wear)jeans,I_______(look)theworst.Also,I’mnotsurehowto______(go)totheparty.IfI______(walk),it________(take)metoolong.IfI_______(take)ataxi,it______(be)tooexpensive.Canyougivemesomeadviceplease?TinatellshavewearwilllookgowalkwilltaketakewillbePoints1.know;do句意“我不知道明晚参加迈克的生日聚会的事怎么做？”don’t后跟动词原形；whatto+动词形式，复合不定式结构。2.think本句表达一客观事实，主语parents是复数形式，故用一般现在时态。句意“我父母认为我应当为下周的英语考试而学习”

。3.go;willbe本句是含if条件状语从句的主从复合句；应遵循主将从现原则。句意“如果我去参加聚会，他们会很失望。”4.tells;have

本句为but连接的并列句，后半句为一般现在时，故前半句也应是一般现在时，主语Mike是第三人称单数形式，故填tells；don’t后跟动词原形。5.wear;willlook

本句为含if条件状语从句的主从复合句，应循主将从现原则。句意“如果我穿牛仔，我看起来会很糟糕。”6.go;howto+动词原形

表示“如何做某事”，是复合不定式结构。8.take;willbe本句为含if条件状语从句的主从复合句，应循主将从现原则。句意“如果我乘出租车去，又将会很贵。”。7.walk;willtake

本句为含if条件状语从句的主从复合句，应循主将从现原则。句意“如果我步行去，将会花费我很多时间。”Completethesentencesusingyourownideas.1.IfIgetuplatetomorrow,____________________________
