——if與unless引導(dǎo)

真實(shí)性條件狀語(yǔ)從句渡普中學(xué)徐愛(ài)玲1/14一.什么叫條件狀語(yǔ)語(yǔ)從句？

由連接詞if或unless引導(dǎo)狀語(yǔ)從句叫做條件狀語(yǔ)從句。條件狀語(yǔ)從句用來(lái)說(shuō)明主句動(dòng)作發(fā)生條件，即某一件事情（從句中動(dòng)作）實(shí)現(xiàn)之后，其它事情（主句中動(dòng)作）可能發(fā)生。其中if是“假如，假如”意思.unless是“除非，假如不”意思。

二.if引導(dǎo)條件狀語(yǔ)從句位置：

if引導(dǎo)條件狀語(yǔ)從句，既能夠放在主句之前，也能夠放在主句之后。當(dāng)從句置于主句之前時(shí)，慣用都用逗號(hào)與主句隔開(kāi)。Forexample:Youwillcatchthebusifyougetupearly.==Ifyougetupearly,youwillcatchthebus.2/14三.if引導(dǎo)條件狀語(yǔ)從句中主從句時(shí)態(tài)：1.若主句是普通未來(lái)時(shí)，if引導(dǎo)從句用普通現(xiàn)在時(shí)。Forexample:

Ifitrainstomorrow,I’llstayathome.2.

假如主句是祈使句或含情態(tài)動(dòng)詞can,may,must，等時(shí)，從句也用普通現(xiàn)在時(shí)。Forexample:1).Youmustseethedoctorifyouareill.2)Don’twearwarmclothesifyouwanttogoskating.1.主句不能用begoingto表示未來(lái)時(shí)，只能用will!2.在if引導(dǎo)條件狀語(yǔ)從句中，不能使用some,而用any.恪守“主將從現(xiàn)”標(biāo)準(zhǔn)。恪守“主現(xiàn)從現(xiàn)”標(biāo)準(zhǔn)。3/14Forexample:Ifyouhaveanyquestionstoask,pleasecometomyoffice.Exercise:練習(xí)Ⅰ.單項(xiàng)選擇（）1.Ifyou_____totheparty,you’llhaveagreattime.A.willgoB.wentC.goD.going（）2.I____hertheanswerifshe____me.A.cantell,willaskB.willtell,willaskC.wouldtell,askD.cantell,asks（）3.–Whatareyougoingtodotomorrow?--We’llgotothelibrarytomorrowifit___.A.isn’trainB.rainC.won’trainD.doesn’train（）4.Pleaseopenthewindowifyou_____

3.除非你愈加小心點(diǎn)，不然你就會(huì)出事故。Unlessyou_______morecare,you_______anaccident.6/14五.條件狀語(yǔ)從句和主句還有一個(gè)共同搭檔，有時(shí)它能夠代替從句和主句，它就是‘‘祈使句+and/or+簡(jiǎn)單句”。其中and表示句意順承；or則表示轉(zhuǎn)折，意思為“不然”。Forexample:1.Ifyouworkharder,you’llpasstheexam.==Workharderandyou’llpasstheexam.2.Ifyoudon’thurryup,you’llmissthetrain.==Hurryup,oryou’llmissthetrain.同義句轉(zhuǎn)換:

1.Studyhard,oryouwon’tpasstheexam.Ifyoustudyhard,you__________theexam.2.Takeataxi,andyou’llcatchthetrain._____you_____ataxi,you’llcatchthetrain.

7/143.Ifyougotobedearly,youwon’tfeeltiredinthemorning._______________early,_____youwon’tfeeltiredinthemorning.

4.Ifyoudon’tworkhard,yourteacherwillprobablybeangry.___________,_____yourteacherwillprobablybeangry.5.Breathedeeplyforoneminute,andyou’llfeelrelaxed._____you______deeplyforoneminute,you__________relaxe.8/14一.概念：二.從句位置：1）主句在前，從句在后，句末一個(gè)標(biāo)點(diǎn)符號(hào)。2）從句在前，主句在后，中間用逗號(hào)隔開(kāi)。三.主從句時(shí)態(tài)：1）主將從現(xiàn)。2）主現(xiàn)從現(xiàn)。（條件：從句有情態(tài)動(dòng)詞或是祈使句）四.unless引導(dǎo)條件狀語(yǔ)從句：（====if...not....除非/假如...不....)五.與“祈使句+and/or+簡(jiǎn)單句”之間轉(zhuǎn)換：9/14
