形式:主语+动词原形+宾语

一般现在时的用法:
1) 经常性或习惯性的动作,常与表示频度的时间状语连用。
时间状语: always, usually, regularly, every morning/night/evening/day/week, often, sometimes, occasionally, from time to time, twice a week, rarely, seldom, once a month hardly ever, never.
I leave home for school at 7 every morning.
2) 客观真理,客观存在,科学事实。

3) 表示格言或警句中。

第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。再如:Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。

We leave very soon.
我们很快就离开。

基本形式(以do为例):
主动态:do
被动态:be done
过去时:did
第三人称单数形式:does
第三人称单数问题
一般现在时中,当主语是第三人称单数时,即常在动词原形后加-s或-es。
第三人称单数变化,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.他喜欢看电视。
She has l unch at twelve.她十二点吃午餐。
It looks like a cat.它看起来像只猫。
2.单个人名、地名或称呼作主语;用第三人称单数。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。
3.单数可数名词或"this / that / the/ a +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。
4.不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时,第三人称单数。
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。
5.不可数名词作主语时为第三人称单数。如: ①The milk is in the glass. ②The bread is very small.
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" ②"I" is a letter.
发音规则
动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同,请认真观察。
1、大多数动词在词尾加“S”在清辅音后发音为[s],在浊辅音及元音后发音为 [z]。如:
①stop-stops [s] ; make-makes [s]
②read-reads [z] ; play-plays [z]
2、以辅音字母加“y”结尾的,要先将“y”变为“i”,然后在加“es”读[iz] 如:
fly-flies [z]; carry-carries [z]
study-studies [z]; worry-worries
3、以“s, x, ch, sh”结尾的,在词尾加“es”,发音为[iz] 如:
tea ch-teaches [iz]; watch-watches [iz]
4、以“o”结尾的动词,加“es”,读[z] 如:
go-goes [z] do-does [z]
注:下面几个动词变为单数时,原词的元音部分的发音发生了较大的变化,请注意记忆。 如:
1、do [du:]-does [dz]
2、say [sei]-says [sez]
以不发音字母“e”结尾的开音节词,如果尾音是[s],[z]时,加“s”后字母“e”发音, 与所加“s”
一起读做[iz] 。 如:
close-closes [iz]
