动词第三人称单数.doc

动词的第三人称单数在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚以及部分同学不知道否定与疑问的变化，现归纳总结如下：一、人称代词he, she, it是第三人称单数。如：He likes watching TV. 他喜欢看电视。She has lunch at twelve. 她十二点吃午餐。 It looks like a cat. 它看起来像只猫。二、单个人名、地名或称呼作主语；是第三人称单数。如： Han Mei looks like her mother. 韩梅看起来像她的母亲。 Beijing is in China. 北京在中国。 Uncle Wang often makes cakes. 王叔叔经常做蛋糕。三、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。如： A horse is a useful animal. 马是有用的动物。 This book is yours. 这本书是你的。 That car is red. 那辆小汽车是红色的。 The cat is Lucys. 这只猫是露茜的。四、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时，是第三人称单数。如： Everyone is here. 大家到齐了。 There is something wrong with the watch. 这块手表有毛病。 This is a pen. 这是一支钢笔。 That is an eraser. 那是一块橡皮擦。五、不可数名词作主语时为第三人称单数。如： The milk is in the glass. 牛奶在玻璃杯里。 The bread is very small. 那面包很小。六、当数字或字母作主语时，看作第三人称单数。如： 6 is a lucky number. 6是个吉利数字。I is a letter. I是个字母。 七、 三单形式的否定：be动词做谓语：在be动词后面加not（注意可以缩写）实义动词做谓语：doesnt do(动词原形)。 He likes apples He doesnt like apples八、 三单形式的一般疑问：be动词做谓语：把be动词提到主语前 He is a good man.
