一般现在时的用法小结
1、定义:一般现在时表示现在经常反复发生的动作、存在的状态或习惯性的动作。
2、构成:一般现在时用行为动词的原形,
但第三人称单数作主语时,动词的词尾要加-S或-es。
规则:以辅音字母加“y”结尾的词,要把“y”变为“i”再加“es”,以“o s x ch sh ”结尾的词加“es”,be动词的变化形式是am \is\ are
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: every?, sometimes, usually often once a week on sundays
I leave home for school at 7 every morning.
Sometimes,he plays baskateball with his father.
She usually goes to school at 7:00.
We often visit that old teacher on Sundays.
2) 客观真理,客观存在,科学事实。
The earth moves around the sun.
Shanghai lies in the east of China.
3) 表示格言或警句中。
Pride goes before a fall.骄者必败。
No man but errs
注意:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。 例:Columbus proved that the earth is round..
4) 现在时刻的状态、能力、性格、个性。
I don't want so much.
Ann Wang writes good English but does not speak well.
比较:Now I put the sugar in the cup.
I am doing my homework now.
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。
在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式,即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚,现归纳总结如下:
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,nothing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。
在下列情况下表示将来:
1. 在状语从句中用一般现在时代替一般将来时。如:
I will give it to him as soon as I see him. 我一看见他就交给他。
He will come if you invite him. 如果你请他,他会来的。
Suppose he doesn’t agree,what shall we do?假如他不同意,那怎么办?
I shall do as I please. 我高兴怎么做就怎么做。
He will continue the work no matter what happens. 不管发生什么情况他都要继续这项工作。
2. 在the more…the more …(越……越……) 句型中,前者通常用一般现在时代替一般将来时,因为前者相当于条件状语从句。如:
The harder you study, the better results you will get. 你学习越努力,成绩就会越好。
3. 在make sure (certain) , see to it, mind, care, matter后的宾语从句的谓语动词用一般现在时代替一般将来时。如:
See to it that you are not late again. 注意别再迟到了。
4. 表示按计划或时间表将要发生的动作,通常有表示将来的时间状语。如:
The plane takes off at 11:30 and arrives in Shanghai at l:20. 飞机十一点半起飞,一点二十分抵达上海。
注:只限于少数动词能这样用,如 begin, start, , end, finish, stop, go, come, leave, sail, arrive, return, close, open 等。
