動詞不定式和動詞-ing講練無答案

動詞不定式和動詞-ing動詞不定式三注意：動詞不定式是動詞的非謂語形式之一，常由“to+動詞原形”構成，可在句中作主語，表語，賓語，賓語補足語，狀語等。今天，咱們主要談談關于它的三個要多加注意的方面。.作賓語的動詞不定式何時省略to我們知道，像ask,want,invite,wish,expect,warn等動詞后常接帶to的動詞不定式作賓語補足語。那什么時候把to省略呢？常見的有“一感二聽三讓四看半幫助”幾種情況。即feelsbdosth；listen/hearsbdo；make/let/havesbdosth;lookat/see/watch/noticesbdosth;helpsb(to)dosth如：IoftenhearMollysingsongsinherroom.我經(jīng)常聽見莫利在她的房間里唱歌。Don’tmakehimstandoutside.別讓他在外邊站著了?！局R拓展】①若表示“看到/聽到/感覺到某人正在做某事"，則用see/hear/feelsbdoingsth.如：Icanhearsomeonesingingatthedoor.我能聽見有人正在問口唱歌。②在被動語態(tài)中，這些不定式中被省略的to要還原。如：Hewasmadetodomorework.他被要求做更多的工作。Shewasseentoplaybasketball.他被看見在打籃球。.疑問詞+不定式不定式可以和疑問詞what,how,when,where等連用，共同作句子的賓語或表語等，但此時不定式一定要放在疑問詞的后面。如：Canyoushowmehowtoturnoffthecomputer?你能讓我看看如何關電腦嗎？（howtodosth作賓語）Wheretospendtheweekendhasn’tbeendecidedyet.去哪里度過周末還沒有被決定出來呢。（wheretodosth作主語）.不定式和it不定式可以作句子的主語和賓語，但有時候它們因太長而顯得句子結構不夠完美，故常用it來代替它作形式主語或形式賓語。常見的句型有以下兩個：①Itbe+adj+forsbtodosth對某人來說做某事怎么樣。（it作形式主語）②sbthinks/findit+adj+todosth.某人認為（發(fā)現(xiàn)）做某事怎么樣。（it作形式賓語）如：Itisveryeasyformetoanswerthatquestion. 對我來說，回答那個問題是很容易的。Didyoufindithardtosolvetheproblem?你覺得解決那個問題很難嗎？練一練：用括號內(nèi)所給單詞的正確形式填空。Canyoutellmehowtothecinema?（go）Itisveryeasyforhimthatproblem.（solve）Listen!Canyouhearsomeoneatourdoor?（knock）Hewasmadehisnameontheblackboard.（write）Weoftenseehimbooksontheplayground.（read）Ifindithardanewlanguage.（learn）教你認識動詞-ing形式在本單元的學習中，我們在很多地方都見到了動詞-ing形式（即v-ing）。它們的用法都一樣嗎？在句中又作什么成分呢？【概念】在英語中，動詞的-ing形式既可能是現(xiàn)在分詞，又可能是動名詞，是由動詞原形加上ing構成的。如swim-swimming，stand-standing等?！粳F(xiàn)在分詞】現(xiàn)在分詞常用于現(xiàn)在或過去進行時態(tài)，與be動詞（即am,is,are或was,were）作句子的謂語。如：Theyareswimmingintheriver.它們正在河里游泳。Look!Thegirlisflyingakiteoverthere.看！女孩正在那邊放風箏。此外，現(xiàn)在分詞在句中還可作一下成分：（1）作定語，表示主動或動作正在進行。如：Thegirlsittingunderthetreeismysister,正坐在樹下的那個女孩是我的妹妹。（2）作表語，表示主語的特征。如：Thenewsissosurprisingthatwehardlybelieveit.這個消息如此令人吃驚，以至于我們幾乎都不能相信。（3）作賓語補足語，表示賓語執(zhí)行的動作正在進行，常用于see/hearsb.doingsth.等句型中。如：IheardhimsinginganEnglishsongwhenIpassedhisroomlastnight.昨天晚上經(jīng)過他的房間時，我聽見他正在唱英語歌。（4）作狀語，可用來表示時間、原因、方式、伴隨或結果等。如：Shesattheresinging.他坐在那兒唱歌。（伴隨狀語）Beingsopoor,hecouldn,tgettoschoc因l為太窮了，所以他不能去上學。（原因狀語）【動名詞】動名詞是一種非限定動詞，它兼有動詞或名詞的特征。在句中可作主語、表語、定語等，常見用法如下：（1）作主語。如：Readinginthesunisbadforoureyes.在太陽底下看書對我們的眼睛不好。Iseatingworsefruitgoodforourhealth?吃腐爛的水果對我們的健康有益嗎？（2）作表語，表示一個抽象動作，說明主語的內(nèi)容。如：Myhobbyiscollectingstamps.=Collectingstampsismyhobby.（3）作賓語，常放在動詞或介詞后面。如：①常接動名詞作賓語的動詞有enjoy,finish,practice,mind,stop,love,like,dislike等。如：Whendidyoufinishwritingyourcompositionyesterday?昨天什么時候你寫完你作文的？②常接動名詞作賓語的介詞或含有介詞的短語有beinterestedin,stop???from?…，begoodat,dowellin,betalentedat,whata-bpifeellike,awayof等。如：Canyouthinkofawayofsolvingthisproblem?你能想出解決這個問題的方法嗎/Wemuststopthemfromcuttingdownthetrees.我們必須阻止他們砍樹。（4）作定語，說明所修飾名詞的用途。Thereisabigswimmingpoolinmyyard.在我的院子里有一個游泳池。Doingsth1完成某事情finishdoingsth2喜歡做某事like/enjoydoingsth/3討厭做某事hatedoingsth去游泳/遠足goswimming/hiking購物/看書dosomeshopping/reading買票劃船buyticketsforboating掰完玉米后afterpickingcorns擅長做某事begoodatdoingsth.做某事遇了些問題havesomeproblems(in)doingsth獲得樂趣havefundoingsth忙于干某事bebusydoingsth感謝您做某事Thankyoufordoingsth做某事怎樣？What/Howaboutdoingsth.?跑步有益健康。Runningisgoodforhealth.Dosth最好干某事hadbetterdosth16讓某人做某事letsbdosth.
