tocatchthebus.2.Hemadeapromise

tocomehereontimetomorrow.1.当修饰的名词是ability,ambition,attempt,chance,courage,desire,decision,effort,failure,moment,promise,right,time,wish…（一些表示企图、努力、愿望、打算、能力

等意义的名词）只能用动词不定式作定语的情况例：1.Hewasthefirstonetothinkoftheidea.2.Youaretheonlypersontobelate.3.Themanageristhelasttocometothemeeting.2.当修饰的名词前有theonly,thenext,thebest,thefirst,thelast,

以及由序数词或形容词最

高级修饰的名词常常用不定式作定语。只能用动词不定式作定语的情况例：1.Doyouhaveanything

tosay?2.Thereisnothing

toworry

about.3.Iwanttogetsomething

todrink.3.当修饰的词为something,nothing,anything

等不定代词时。4.当定语表示未来的还没做的动作时。例：Thelettertobewrittenistomyfather.Themattertobediscussedisimportant.（二）作结果状语不定式作状语，用来修饰动词、形容词和副词。1.动词不定式表示结果时，其逻辑主语就是句子的主语。结果状语常常只限于learn,find,see,hear,tobetold,make,turnouttobe等具有界限含义的动词。

Hereturnedhometolearnhisdaughterhadjustbeenrescued.Dinosaurshavecompletelydiedoutontheearth,nevertobeseenagain.2.动词不定式作结果状语的结构不定式常与only,enough或too连用，用于“too...to”，“enoughto...”，“onlytodo”句型中。例：Hestudiedhardonlytofailtheexam.Heisoldenoughtogotoschool.Sheissoproudastolookdownuponothers.现在分词与不定式作结果状语的区别例：1.HewenthometofindhisoldfriendGeorgeoutsidethedoor.2.Thechildfell,strikinghisheadagainstthedoorandcuttingit.动词不定式作结果状语强调的是一种意想不到的结果；而现在分词作结果状语强调的是一种顺承的，必然造成的结果。PracticeTranslatethefollowingsentences.1.少吃点油炸食品是个好主意。2.你需要在安静的地方学习。3.我告诉他不要放弃。4.你能给我一些可以写字的纸吗？5.我大声朗读来锻炼我的发音。6.我跑到车站，却被告知火车已经离开了。Translatethefollowingsentences.1.少吃点油炸食品是个好主意。2.你需要在安静的地方学习。3.我告诉他不要放弃。Itisagoodideatoeatlessfriedfood.Youneedtostudyataquietplace.Itoldhimnottogiveup.PracticeTranslatethefollowingsentences.4.你能给我一些可以写字的纸吗？5.我大声朗读来锻炼我的发音。6.我跑到车站，却被告知火车已经离开了。Canyougivemesomepapertowriteon?Ireadloudlytopractisemypronunciation.Irantothestation,onlytobetoldthatthetrainhadalreadyleft.PracticeFinishexercisesConP64Checkinga.objectb.objectcomplementc.attributived.adverbialofpurposee.adverbialofresult______1I’msorrythatIcannotcometoyourbirthdayparty tomorrowasIhaveanimportantmeetingtoattend.______2Shehurriedtothecinema,onlytofindallthetickets
