三年级语文上册搭船的鸟PPT 人教版三年级语文上册 搭船的鸟 搭船的鸟是什么鸟？ 你喜欢这样的鸟吗？为什么？ 多么美丽的小鸟啊！它有一张红色的长嘴，羽毛是翠绿的，翅膀带有一些蓝色，比鹦鹉还漂亮。 如果你看见这样一只小鸟站在船头，你会产生什么想法？想一想 它什么时候飞来的呢?悄悄地站在船头有多久了？站在那里做什么呢?难道它要和我们一起坐船到外祖父家里去吗? 站在那里到底做什么呢?思考 我正想着，它一下子冲进水里不见了。可是，没一会儿，它又飞出来了，红色的长嘴里衔着一条小鱼。它站在船头，一口把小鱼吞了下去。 动词不定式 不定式由“to+动词原形”构成,其否定形式是“not/nevertodo”,不定式可以带宾语或状语构成不定式短语,没有人称和数的变化,但有时态和语态的变化。不定式可以作主语、宾语、状语、表语和定语，但不能单独作谓语。不定式的逻辑主语有时用“for+名词或代词宾格”构成。不定式 结构:todo(否定)not/nevertodo二.时态与语态主动语态被动语态一般式进行式完成式完成进行式不定式todotobedonetobedoingtohavedonetohavebeendonetohavebeendoing-------------------- (1).Theypretendednottoseeus.(2).Hepretendedtobesleeping.(3).Shepretendedtohaveknownitbefore.(一般式表示与谓语的动作同时/几乎/发生在它之后.)(在谓语动词发生的同时,不定式的动作也正在进行)(完成式表示动作发生在谓语动作之前)(4).We’rehappytohavebeenworkingwithyou.(完成进行式表示谓语动作发生之前,不定式的动作一直在进行而且可能之后也继续) 1.作主语2.作宾语3.作宾语补足语4.作定语5.作状语6.作表语7.作独立成分8.与疑问词等连用 三.用法/功能Toseeistobelieve.It’simportanttolearnEnglishwell.(1).主语单个不定式作主语时,谓语动词用单数若不定式太长,往往用it作形式主语,不定式置后.Myjobtohelpthepatient.Yourtasktocleantheclassroom.isis(2).表语 Iwanttogohome.Theworkersdemandedtogetbetterpay.Ifounditnecessarytotalktohimagain.(3)宾语think/consider/findit+adj.+todo常用动词不定式作宾语的动词有：hope,refuse,learn,setoutchoose,decide,agree,manage,pretend,plan.
