初中(小学)第三人称单数知识点及练习题-浙大研究生编辑.doc

第三人称单数是英语中的一种语法，也称“三单”或“单三”，用于一般现在时的句子。学习和掌握这个知识点，需要从以下几个方面入手：1、 什么是第三人称单数？2、 动词在第三人称单数后如何变化？3、 第三人称句子如何变换？首先，什么是第三人称单数？第一人称就是“我”和“我们”。第二人称是“你”和“你们”。第三人称单数是“他”、“她”和“它”，复数则是“他们”。有以下六种情况：下面我们归纳一下第三人称单数的用法：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： I is a letter. I是个字母。其次，动词在第三人称单数后如何变化？l 一般情况 +s playplays 例：like-likes, drink-drinks, write-writes, smile-smiles, learn-learns等l 以s、x、ch、sh和o结尾 +es 例：go-goes, do-does, catch-catches, watch-watches, teach-teaches, flash-flashes等l 以辅音字母加y结尾 变y为i +es 例：studystudies, fly-flies, worry-worries, carry-carries等l 以f或者fe结尾 变f或fe为v+es 例：lifelives l 特殊情况 不规则 havehas l 注意：情态动词后的动词要保持原型，包括can, may, could, should等，例：He can play basketball well.It may fly away.最后，第三人称的句子该如何变换？考题中有关单三的句子变换有两种形式，第一种是疑问式，第二种是否定式。一般句子变为疑问句有以下两种情况：1. 句子中有be动词，将be动词提到句首即可。例：She is a good student. -Is she a good student?这个句子的回答就是：Yes, she is.2. 句子中没有be动词，只有动词的时候，添加一个do或does到句首即可。例：The dog eats a lot.-Does the dog eat a lot?这个句子的回答就是：Yes, it does.注意，当助动词do或does在句首时，后面的动词要用原形。一般句子变为否定句有以下两种情况：1. 句子中有be动词，直接在be动词后面加not即可。例：Tom is a good student.-Tom is not a good student.2. 句子中没有be动词，需要在句子的动词前加do或does，再加not。例：Lily play piano.-Lily does not play piano. 句子中有主动词do或does， 将do或does提到句首即可第三人称单数练习题一选Do还是Does。1.
