haveto屬于情態(tài)動(dòng)詞，意為“必須，不得不”。但在用法上與情態(tài)動(dòng)詞有所不同，它會(huì)隨著人稱(chēng)與數(shù)及時(shí)態(tài)的變化而變化。它的第三人稱(chēng)單數(shù)用hasto，過(guò)去式是hadto。haveto的疑問(wèn)及否定形式通常借助于助動(dòng)詞do／does／did構(gòu)成。例如：

Sheisn'tverywellthesedaysandhastostayathome．她這幾天身體不太好，不得不待在家里。

We

havetogoandhelphim．我們得去幫幫他。

Youdon‘thavetotellmethis．你不必告訴我這件事。

Doyou

havetodoeverything?

什么事都得你做嗎?

She

hadtoattendthemeetingyesterday．她昨天不得不去參加那個(gè)會(huì)議。情態(tài)動(dòng)詞can的用法

(1)情態(tài)動(dòng)詞can可用來(lái)表示請(qǐng)求許可或提供幫助。例如：Can1helpyou?要我?guī)兔?(2)含有情態(tài)動(dòng)詞can的一般疑問(wèn)句應(yīng)將can置于主語(yǔ)之前?；卮饡r(shí)應(yīng)用can／can’t。例如：

Canlhavealook?我可以看一看嗎?Yes，youcan．／No，youcan't．是的，你能。／不，你不能。(3)含有can的肯定句變否定句時(shí)，可以直接can后面加上not，可縮寫(xiě)為can‘t。例如：

Ican'tdoit.我不會(huì)做。Ican'thelpyou．我?guī)筒涣四恪?)1.Weshould___eachother.A.helpB.tohelpC.helpingD.helps()2.Afterlunch,Iwash_________________.A.thedishB.dishesC.thedishesD.dish()3.Theoppositeof“outside“is_______________.A.insideB.inC.outD.intoACA()4.Don’tsleep__________.A.intheclassB.inclassC.athereD.fromhere()5.Let’smeet_______nineo’clock.A.atB.inC.toD.on()6.Hedoesn’t______getupsoearlyA.havetoB.hastoC.hadtoD.must()7.Who_____yourbedeverynight?A.makeB.ismakingC.makesD.putsBAAC()8.Iputonmyglasses____theblackboardclearly.A.seeB.toseeC.forseeD.seeing()9.__________Ismokehere.Yes,you_________.A.Can,mayB.Can,can’tC.Can,canD.May,do()10.Youcan’tsingthissong.Ican’tsingit________.A.tooB.also
