haveto属于情态动词，意为“必须，不得不”。但在用法上与情态动词有所不同，它会随着人称与数及时态的变化而变化。它的第三人称单数用hasto，过去式是hadto。haveto的疑问及否定形式通常借助于助动词do／does／did构成。例如：

Sheisn'tverywellthesedaysandhastostayathome．她这几天身体不太好，不得不待在家里。

We

havetogoandhelphim．我们得去帮帮他。

Youdon‘thavetotellmethis．你不必告诉我这件事。

Doyou

havetodoeverything?

什么事都得你做吗?

She

hadtoattendthemeetingyesterday．她昨天不得不去参加那个会议。情态动词can的用法

(1)情态动词can可用来表示请求许可或提供帮助。例如：Can1helpyou?要我帮忙吗?(2)含有情态动词can的一般疑问句应将can置于主语之前。回答时应用can／can’t。例如：

Canlhavealook?我可以看一看吗?Yes，youcan．／No，youcan't．是的，你能。／不，你不能。(3)含有can的肯定句变否定句时，可以直接can后面加上not，可缩写为can‘t。例如：

Ican'tdoit.我不会做。Ican'thelpyou．我帮不了你。()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
