如何判断一个单词是不是单数第三人称

如：x0dHe likes watching TV.他喜欢看电视.x0dShe has lunch at twelve.她十二点吃午餐.x0dIt looks like a cat.它看起来像只猫.x0d二、单个人名、地名或称呼作主语；是第三人称单数.如：x0d①Han Mei looks like her mother.韩梅看起来像她的母亲.x0d②Beijing is in China.北京在中国.x0d③Uncle Wang often makes cakes.王叔叔经常做蛋糕.x0d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：x0d①A horse is a useful animal.马是有用的动物.x0d②This book is yours.这本书是你的.x0d③That car is red.那辆小汽车是红色的.x0d④The cat is Lucy's.这只猫是露茜的.x0d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：x0d①Everyone is here.大家到齐了.x0d②There is something wrong with the watch.这块手表有毛病.x0d③This is a pen.这是一支钢笔.x0d④That is an eraser.那是一块橡皮擦.x0d五、不可数名词作主语时为第三人称单数.如：x0d①The milk is in the glass.牛奶在玻璃杯里.x0d②The bread is very small.那面包很小.x0d六、当数字或字母作主语时,看作第三人称单数.如：

首先要知道 he she it 这三个词是第三人称单数
其他的，只要能用这三个词所代替的都是第三人称单数
例如 your father→ he
his mother→she
a dog → it
a cup of coffee→ it
你慢慢钻研一下，平时多积累
