动词--实义动词教学课堂学案
知识经纬
1. 认识助动词,了解其使用及在一般现在时中的使用。
2.区分第三人称单数和助动词do/does的正确使用。
3.了解一般现在时,及其各种句型的表达。
【概念引入】
· 动词指的是表示表示动作或状态的词。可以分为系动词(be动词),实义动词,情态动词以及助动词
· be动词
英语中的be动词指的是“am/is/are”的原形,它的意思是“是”。be动词在句子中作谓语动词的时候,要根据句子的主语和时态而变化形式。
· 实义动词
即有实际意义的动词,在动词的各种时态中发生不同的变化,在本册教材里,主要学习动词的一般现在时态。在一般现在时中,实义动词有两种形式:动词原型、第三人称单数形式。
· 当主语是I、we、you、they、复数名词时动词用原型
· 当主语是第三人称单数时(如:he、she、it、单数名词、不可数名词),动词要用三单形式。
1、 第三人称单数
1、 人称代词he, she, it是第三人称单数。
2、 单个人名、地名或称呼作主语;是第三人称单数。
①Han Mei looks like her mother韩梅看超来像她的母亲。
②Beijing is in China.北京在中国。
③Uncle Wang often makes cakes.王叔叔经常 做蛋糕。
3、 单数可数名词或"this / that / the单数可数名词"作主语时,是第三人称单数
①A horse is a useful anima1马是有用的动物。
②This book is yours.这本书是你的。
③That car is red.那辆小汽车是红色的。
④The cat is Lucy' s.这只猫是露茜的。
4、不可数名词作主语时为第三人称单数。
①The milk is in the glass牛 奶在玻璃杯里。
②The bread is very smal1那面包很小。
5、不定代词someone, somebody, nobody, everything, something等是第三人称单数
①Everyone is here. 大家到齐了。
②There is something wrong with the watch这块手表有毛病。
6、数字或字母作主语时,看作第三人称单数。如: .
①"6" is a lucky number. "6是个吉利数字。
②"I" is a letter. "I是个字母。
· 请圈出下列可以作为三单主语的词

she
we

pigs
toy
coffee

二、一般现在时
一般现在时,它描述的是现在时间下经常性、习惯性或普遍性的动作、状态或事实。 这种时态不关注动作发生的具体时间,而是强调其常态性、普遍性或真理性。 在句子中,一般现在时通过使用动词原形或第三人称单数形式来表达。
例句:I like reading books. 我喜欢读书。
在这个句子中,我们并不是在描述某个特定的时间点我正在读书,而是在表达我对读书的喜好,这是一种常态性的行为。
1、 动词三单的变化规则
· 当主语是三单时: 谓语动词 + s或es
· 当主语是非三单时: 谓语动词用原形
· 当谓语是be动词时,要根据主语的单复数变为 is / am / are
谓语动词加 s / es的规则:
(1) 一般情况下直接 + s
(2) 以s / x / ch / sh/o结尾的动词 + esn
(3) 以元y结尾直接 + s; 辅y结尾把y改i + es
(4) 特殊: have-has
