Usingverbs+to-infinitives动词+动词不定式当句子中已经有谓语动词,而我们又要表达不止一个动作概念时,其余的动词可以使用非谓语形式表达。动词不定式就是动词的一种非谓语形式,其基本形式是“to+动词原形”。如：他想课后踢足球。注意:动词不定式在句子中不作谓语,因此没有人称、数和时态的变化。Hewantstoplayfootballafterclass.Mymotherforgottoturnoffthelightsyesterday.我妈妈昨天忘记关灯了。1.动词不定式在句中常作谓语动词的宾语,这一类谓语动词常见的有:agreechoosedecideforgethopelearnlikeplanpreparepromiserefuserememberseemwantwishwouldlikeagreetodosth.同意干begintodosth.开始干decidetodosth．决定干failtodosth.做某事失败forgettodosth.忘记干hopetodosth．希望干learntodosth．学着干plantodosth．计划干preparetodosth.准备干remembertodo.记得干trytodosth．尝试干wanttodo.想要干e.g.Wherewillyouplantovisit

thissummerholiday?今年暑假你打算去哪儿玩？Ihopetowatchthesunset．我想看日落。Iwanttotakesomephotosofthesunrise.我想拍几张日出的照片。moreverbs+todo（作宾语）:needpromise

2.todo做宾语补足语hearsb.doseesb.dowatchsb.domakesb.doletsb.dohelpsb.do但有的动词后跟不带to的不定式作宾补，如:注意：动词不定式的否定形式是“notto+动词原形”。如:Youmustpromisenottobelateagain.你必须保证不再迟到了。remembertodosth.

rememberdoingsth.区分forgettodosth.forgetdoingsth.记得去做某事记得做过某事忘记去做某事忘记做过某事e.g.汤姆,记得课后和我们一起打篮球。我记得上个月写了一封信给你。Tom,remembertoplaybasketballwithusafterclass.Irememberedwritingalettertoyoulastmonth.stoptodosth.

stopdoingsth.e.g.让我们停下来休息一下。不要说话。老师来了。
