tomorrow.Grammar類別構(gòu)成例句簡單句TheSimpleSentence由一個主語（或并列主語）和一個謂語（或并列謂語）構(gòu)成的句子。Igetupatsixinthemorning.MymotherandIoftengoshopping.Somestudentswalkorridebikestoschool.復(fù)合句TheComplexSentence由一個主句和一個或多個從句構(gòu)成的句子。Whatdoyouwanttobewhenyougrowup?Ithink(that)

ScreenCityhasthemostcomfortableseats.句子的類型Grammar狀語從句（AdverbialClause）是指句子用作狀語時，起副詞作用的句子。狀語從句根據(jù)其作用可分為時間、地點、原因、條件、目的、結(jié)果等從句。狀語從句一般由連詞(從屬連詞)引導(dǎo)，也可以由詞組引起。WhileJohnwaswatchingTV,hiswifewascooking.（時間狀語從句）當(dāng)約翰看電視時，他的妻子正在做飯。Hedidn’tattendclassesyesterdaybecausehewasill.（原因狀語從句）他病了，所以他昨天沒有來上課。Hegotupsoearlythathecaughtthefirstbus.（目的狀語從句）他很早起床以便趕上第一班公共汽車。We’llstartourprojectifthepresidentagrees.（條件狀語從句）如果總統(tǒng)同意，我們將開始我們的項目。狀語從句Grammarif引導(dǎo)的條件狀語從句在復(fù)合句中作條件狀語的句子叫條件狀語從句。條件狀語從句常用if來引導(dǎo)。If從句既可放在主句前，也可放在主句后。放在主句前，要用“,”與后面的主句隔開。語法概述Grammarif條件句放在前，逗號要放主句前。if條件句表如果，主將從現(xiàn)是關(guān)鍵。if引導(dǎo)的條件狀語從句一.含條件狀語從句的復(fù)合句中主從句的時態(tài)

主句為以下情況之一時，條件狀語從句用一般現(xiàn)在時：（1）主句是一般將來時。Ifitdoesn’traintomorrow,wewillgotothezoo.（2）主句謂語部分含有情態(tài)動詞（may,might,can,must,should等）。Ifyoueat

badfood,youmayfallill.（3）主句為祈使句。Ifthelightisred,waitforaminute.經(jīng)典例句！巧學(xué)妙記Grammar二.有些句子可與含if條件狀語句互相轉(zhuǎn)換。（1）祈使句+and/or+陳述句。Hurryup,oryou’llmissthetrain.=If

youdon’thurryup,you’llmissthetrain.Youwillbehealthierifyoueatwell.=Eatwellandyouwillbehealthier.（2）借助with或without。Youcan’tdrivethecarwiththedooropen.=Youcan’tdrivethecarifthedoorisopen.Ifthereisnowater,fishwilldie.=Fishwilldiewithout
