Reading1.Ifweaskpeopleto

bringfood,they’lljustbringpotatochipsandchocolate…

asksb.todosth.請(qǐng)求/要求某人做某事e.g.Heaskedthedoctor

totellhimthetruth.他請(qǐng)求醫(yī)生告訴他真相。Languagepoints2.Yes,thegameswillbemoreexciting,too.

exciting意為“令人興奮的、令人激動(dòng)的”e.g.Themoviehasanexcitingopening.電影的開頭非常刺激。前者是“對(duì)……感到興奮”，通常主語(yǔ)是人;后者是“令人感到興奮的”，通常主語(yǔ)是物/事件。例如：Areyouexcited

aboutgoingtoBeijing?你要去北京了，感到興奮嗎？

Hetoldusanexcitingstoryyesterday.他昨天給我們講了一個(gè)使人激動(dòng)的故事。exciting&excitedIthinkIwilltakethebustotheparty.Ifyoudo,youwillbelate.IthinkIwillstayathome.Ifyoudo,youwillbesorry.Whatwillhappeniftheyhavethepartytoday?Iftheyhaveittoday,halftheclasswon'tcome.Canshegotothebaseballgame?No.she’snotavailable.Shemustgotothedoctor.Shouldweaskthepeoplebringtofood?Ifweaskpeopletobringfood,they’lljustbringpotatochipsandchocolate.GrammarFocusIf+…,I’ll/you’ll+…

1.Structure這里if所引導(dǎo)的是真實(shí)條件句(realconditional),

即所假設(shè)的條件有可能成為現(xiàn)實(shí),表達(dá)假定所假設(shè)的條件實(shí)現(xiàn)時(shí)會(huì)出現(xiàn)的情況或會(huì)采取的行為。有時(shí),我們可以使用并列結(jié)構(gòu)的祈使句來(lái)表達(dá)這種類型的條件句。e.g.Ifyousetyouralarmclock,youwon’toversleep.如果你上鬧鐘,你就不會(huì)睡過頭了。

Setyouralarmclock,andyouwon’toversleep.Ifyougivehimaninch,hewilltakeamile.他會(huì)得寸進(jìn)尺。

Givehimaninch,andhewilltakeamile.Ifyoudon’tgivehimsomefood,hewillstarve.如果你不給他一點(diǎn)吃的,他就會(huì)餓死。

Givehimsomefood,or/elsehewillstarve.(1)條件狀語(yǔ)從句通常由連詞if引導(dǎo),意為“如果、假如”,主句不能用begoingto表示將來(lái),而應(yīng)該用shall、will。

e.g.Ifyouleavenow,youarenevergoingtoregretit.(錯(cuò)誤)

Ifyouleavenow,youwillneverregretit.(正確)(2)if“如果”,引導(dǎo)條件狀語(yǔ)從句,主句用一般將來(lái)時(shí)，從句則用一般現(xiàn)在時(shí)，如：

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

賓語(yǔ)從句中的if與條件狀語(yǔ)從句if的區(qū)別。賓語(yǔ)從句中的if“是否”相當(dāng)于whether,引導(dǎo)賓語(yǔ)從句,時(shí)態(tài)需根據(jù)語(yǔ)境確定。

Idon'tknowifitwillraintomorrow.我不知道明天是否會(huì)下雨。在if-分句中中用“will＋動(dòng)詞原形”并不單純表示將來(lái)意義，這里的will是個(gè)表示“意愿”的情態(tài)動(dòng)詞,相當(dāng)于bewillingto(愿意)。要注意這種帶“will＋動(dòng)詞原形”的if-分句在某些場(chǎng)合是不可以隨便用的,

比如我們可以說(shuō)：Ifhegetsmyletterintime,he’llbeabletochangehisplans.

如果他及時(shí)收到我的信,他就能改變他的計(jì)劃。卻不可以說(shuō)成：Ifhewillgetmyletterintime,he’llbeabletochangehisplans.另外,在if-分句中還可能使用“would＋動(dòng)詞原形”的結(jié)構(gòu)，這種用法還是表示“意愿”,常用于表示客氣的請(qǐng)求,這時(shí)主句動(dòng)詞既可以用will/shall＋動(dòng)詞原形,也可以用would/should/could/might＋動(dòng)詞原形。如：IfyouwouldtryItalianfood,youwouldlikeit.如果你愿意嘗嘗意大利食物,你會(huì)喜歡它的。Ifyouwouldreservetheseats,wewouldbesureofacomfortablejourney.如果你愿意訂座,我們將肯定會(huì)有一個(gè)舒適的旅程。1.如果你不趕快走,你就會(huì)遲到。2.如果你愛你的父母,你應(yīng)當(dāng)幫他們做做家務(wù)。3.如果你更友善一些,你會(huì)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“我不知道明晚參加邁克的生日聚會(huì)的事怎么做？”don’t后跟動(dòng)詞原形；whatto+動(dòng)詞形式，復(fù)合不定式結(jié)構(gòu)。2.think本句表達(dá)一客觀事實(shí)，主語(yǔ)parents是復(fù)數(shù)形式，故用一般現(xiàn)在時(shí)態(tài)。句意“我父母認(rèn)為我應(yīng)當(dāng)為下周的英語(yǔ)考試而學(xué)習(xí)”

。3.go;willbe本句是含if條件狀語(yǔ)從句的主從復(fù)合句；應(yīng)遵循主將從現(xiàn)原則。句意“如果我去參加聚會(huì)，他們會(huì)很失望。”4.tells;have

本句為but連接的并列句，后半句為一般現(xiàn)在時(shí)，故前半句也應(yīng)是一般現(xiàn)在時(shí)，主語(yǔ)Mike是第三人稱單數(shù)形式，故填tells；don’t后跟動(dòng)詞原形。5.wear;willlook

本句為含if條件狀語(yǔ)從句的主從復(fù)合句，應(yīng)循主將從現(xiàn)原則。句意“如果我穿牛仔，我看起來(lái)會(huì)很糟糕?！?.go;howto+動(dòng)詞原形

表示“如何做某事”，是復(fù)合不定式結(jié)構(gòu)。8.take;willbe本句為含if條件狀語(yǔ)從句的主從復(fù)合句，應(yīng)循主將從現(xiàn)原則。句意“如果我乘出租車去，又將會(huì)很貴?！?。7.walk;willtake

本句為含if條件狀語(yǔ)從句的主從復(fù)合句，應(yīng)循主將從現(xiàn)原則。句意“如果我步行去，將會(huì)花費(fèi)我很多時(shí)間?！盋ompletethesentencesusingyourownideas.1.IfIgetuplatetomorrow,____________________________
