1、长沙市天心区第一中学刘彩虹微课说明稿内容：非谓语动词语法方式：采用ppt 屏幕录像机 麦克风制作：利用手机录像，然后利用QQ影音将原影音资料转换成flv文件。微课内容： 语非谓语动词讲解及练习 非谓语动词是指分词（包括现在分词和过去分词）、不定式、动名词等三种形式，即： doing , done , to do , doing 。当然它们有各自不同的变化形式，如： 现在分词 doing : 有being done（被动式） ; having done （完成式）; having been do ne （完成被动式） 不定式 to do : 有to be done （被动式）; to have
2、done （完成式）; to be doing（进行式） 动名词 doing : 有having done（完成式）; being done（被动式） ; 非谓语动词的特点： 三种非谓语动词都具有动词的特征，虽然它们没有人称和数的变化，但是它们都能带自己的状语或有时跟宾语。它们都有各自的特征：分词具有形容词和副词的特征；动名词具有名词的特征；不定式具有名词、形容词和副词的特征。具体来讲：分词在句子中可以做定语、表语、状语或补足语等；动名词在句子中可以做主语、宾语、表语等；不定式在句子中可以做主语、宾语、表语、补足语或状语。 下面分别对三种非谓语动词进行讲解： 一、动词不定式 先看几个例句，判断

5、ank to , devote to , next to , belong to , be used to , look forward to 2 带to 还是不带to I have no choice but to give in I cannot do anything but give in I saw him enter the classroom . （ 但是： He was seen to enter the classroom .） 3 动词不定式逻辑主语是由for 作为标记的。但是有时用of .

7、fail , manage , offer , prepare , continue , ask , mean , choose , expect etc. 需要宾语补足语的动词不能用动词不定式直接做介词的宾语，而要用it做形式宾语。例如：通常不说We think to obey the laws is important . 而说We think it important to obey the laws . 5不定式的省略。下列短语中，如果意义明确，常常省略到to 。 want to , wish to ,hope to , like to , hate to , plan to , tr
8、y to , love to , have to , o ught to , need to , used to , be able to 6不定式作定语，应注意两种关系： 1）动宾关系： He has a lot of meeting to attend . Please lend me something to write with .

9、 best way to travel ( by ) is on foot . There is no time to think ( about ) . 2）主谓关系： She is always the last ( person) to speak at the meeting . -Im going to the post office , for I have a letter to post . ( 逻辑主语是I ) -Thank you.
