E、作状语可以表结果、原因、目的、条件。如：Shewenttoseeadoctor.她去看医生了。（目的）Heismadtohearthenews.他听到这消息疯了。（原因）Theboyisnotoldenoughtogotoschool.这男孩还不到上学年龄。（结果）Tostudyhard,you’llmakegoodprogress.努力学习，就会取得好成绩。（条件）动词不定式F、作定语（必须后置）如：Hehasnothingtodo.他无事可做。There’snotimetothinkaboutit.没有时间考虑此事。注意：不定式作定语与所修饰的词之间存在着逻辑上的主谓/动宾。如：Heisthelastmantoleave.他是最后一个离开的人。（主谓关系）Shesaidshehadalotofworktodo.她说她有许多工作要做。（动宾关系）注意：不定式作定语若是逻辑上的动宾关系，不定式是不及物动词的话，后应跟着一个相应的介词，但如果被修饰的是place、time、way就除外。如：Wemustrentahousetolivein.Thatisaverygoodplacetolive.在学习动词不定式的时候还有两点要注意哦！1、“一感二听三让四看见”，要用省to的不定式作宾补,但变为被动句时，要加上to,如（feel,hear,listento,see,watch,notice,lookat,have,make,let）e.g.1）Wehearhimsinginthenextroom.Heisheardtosinginthenextroom.2、动词不定式的否定形式为：not+todoMr.Smithaskedtheboy___________(notplay)thiskindofgame.nottoplayPleasehavehim__________(notdo)somuchhousework.notdo牛刀小试1.?Mymotheroftenasksme_____somecleaningonSundaysAdoB.doesC.didD.todo2.?–DoyouoftenhearJohn_____inhisroom?–Listen!Nowwecanhearhim____inhisroom.A.sing,tosingB.sing,singC.sing,singingD.tosing,singing3.?Iwatchedher______inthenextroomlastnight.A.dancingB.todanceC.dancesD.dance4.Let’s______swimmingaftertheexam.A.goB.goesC.togoD.went5.?You’dbetter_______abus.A.tocatchB.catchC.catchesD.catchingDCAAB特殊词精讲:tododoingrememberforget要去做已做过stopgoon两件事一件事likehatelove一次性经常性习惯try尽力做尝试做Start，begin一样一样stopdoing/todosth.stoptodo停下来去做另一件事，stopdoing停止正在做的某事。Eg:他们停下来吸烟。Theystoptosmoke.停止扔垃圾Pleasestopthrowingrubbish.forgettodo忘记要去做某事，forgetdoing
