一般如今时讲授和演习

三.用法:
1.确定句:

他用is.

留意的问题:第三人称单数以及第三人称单数时动词的变更规矩
在一般如今时中,当主语是第三人称单数时,谓语动词要用第三人称单数情势,即常在动词本相后加-s或-es.但有些同窗们对于哪些主语是第三人称单数还不十分清晰,现归纳总结如下:
1.人称代词he, she, it是第三人称单数.如:
He likes watching TV. 他爱好看电视.
She has lunch at twelve. 她十二点吃午餐.
It looks like a cat. 它看起来像只猫.
2.单小我名.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 ma kes 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.如:
①A horse is a useful animal. 马是有效的动物.
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.不定代词someone, somebody, nobody, everything, something等及指导代词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. 这块手表有缺点.
③This is a pen. 这是一支钢笔.
④That is an eraser. 那是一块橡皮擦.
5.不成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.
6.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.
动词+s的变更规矩
1.一般情形下,直接加-s,如:cook-cooks, make-makes
runs gets likes collets takes plays climbs
2.以s. x. sh. ch. o结尾,加-es,如:guess-guesses, wash-washes, watch-watches, go-goes
3.以“子音字母+y”结尾,变y为i, 再加-es,如:
study-studies
办法与发音:
1.一般情形下,直接加-s
eg. works, plays, rains, sees
2.以sh, ch, s, x 或o 结尾的词后加–es
eg. washes, teaches, fixes, does, goes
3.以子音字母加-y 结尾的,先把‘y’ 改成‘i’, 再加-es
eg. studies, flies, carries
留意: 动词加-s 今后的读音.
