动词不定式讲解课件
概说
动词不定式(to do)是初中英语课的 一个重点，也是中考要考查的一个项目。 动词不定式属于非谓语动词的一种形式， 很多同学经常把它和谓语动词混在一起，
掌握起来有困难。下面我们对动词不定 式的用法做简单归纳，帮助同学们记忆
动词不定式的主要用法 一、动词不定式在句子中不能独立 充当谓语, 没有人称和数的变化。 二、动词不定式是由“to+动词原形” 构成(有时可以不带to)。动词不定式的 否定形式是“not+动词不定式”(此时 not不能再与助动词连用)。
巧记动词不定式作宾语歌诀：
• 想要拒绝莫忘记
• （want, refuse, forget） • 需要努力就学习 • （need, try, learn） • 喜欢帮助加同意 • （like help agree ） • 希望决定后开始 • （hope, decide, begin, start）
点击规律：在find \ feel \ think\ consider
+ it + adj．+ to do sth．句型中，it是形式
宾语, 真正的宾语是后面的动词不定式。
I found it very difficult to get a job. (it为形式宾语)
如：
The man downstairs found it difficult to get to sleep．
• You must remember to lock the door when you leave
动词不定式基本用法口诀
• 不定式有标记， to与动原连一起。 • 没有人称数变化， 动词特点它具备。 • 主宾定状表状语， 惟独作谓不可以。 • not加上不定式， 否定结构要牢记。 • 疑问词与不定式， 构成短语有意义。 • 仔细推敲多思考， 准确判断有依据。
