英语基础那些重要 英语入门第三人称单数细致讲解


主语+谓语+宾语
She reads books.
概念:在一般现在时中,当主语为第三人称单数时,动词要用“s”型(即第三人称单数形式) 。所谓动词“s”型的构成,可按名词变复数的规则来记,
变化规则即:1)在动词尾直接加 s 。如:
play—plays,want—wants,work—works,know—knows,help—helps,get—gets
2)以字母s、x、ch、sh或o结尾的动词加-es;如:
guess—guesses,fix—fixes,teach—teaches,brush—brushes,go—goes,do—does,watch—watches,catch—catches
3)以辅音字母+y结尾的动词,先变y为i,再加-es 。如:
study—studies,carry—carries,fly—flies,worry—worries
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:
①Han Mei looks like her mother. 韩梅看起来像她的母亲 。
②Beijing is in China. 北京在中国 。
③Uncle Wang often makes cakes. 王叔叔经常做蛋糕 。
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:
①A horse is a useful animal. 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 。
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:
①Everyone is here. 大家到齐了 。
②There is something wrong with the watch. 这块手表有毛病 。
③This is a pen. 这是一支钢笔 。
④That 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:
①The milk is in the glass. 牛奶在玻璃杯里 。
②The 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:
①"6" is a lucky number. "6"是个吉利数字 。
②"I" is a letter. "I"是个字母 。
七、关于do和does的使用方法:
1)第三人称单数用了 does 后面就不用动词的s形式了,而用动词原形.
2)变为疑问句,要在句首加"do" does ; 变为否定句, 要在动词前面加"do not ,does not", 可以简写为 "don't".
