【一般现在时】一、定义与讲解:一般现在时表示经常或习惯性的动作或一般性事实。

也可表示现在的状态或主语具备的性格和能力。

◆通常与副词every day(每天),always(总是),usually(通常),often(经常)sometimes(有时)hardly ever(几乎不)等时间状语连用。

例:(1)表示事物或人物的特征、状态。

The sky is blue.天空是蓝色的。

Mary’s father is an English teacher. 玛丽的爸爸是一名英语老师。

(2)表示经常性或习惯性的动作。

I get up at six every day.我每天六点起床。

(3)表示客观现实。

The table has four legs.桌子有四条腿。

(4)表示客观真理,科学原理,自然现象,等客观事实或格言谚语等。

The earth goes around the sun.地球绕着太阳转。

(5)表示平日的喜好。

I like bananas. We don’t like vegetables. She doesn’t like strawberries. 二.只有主语在第三人称单数时用动词的“三单形式”,其他人称用动词原形。

★动词三单形式的变化规则:1.(1)多数直接在动词词尾加-s.play — plays like — likes ask---asks work---works get---gets call---calls (2)以字母s, x, ch, sh或o结尾的动词,在词尾直接加-es.watch---watches wish---wishes do---does go---goes(3)以“辅音字母加 - y”结尾的动词,要先变y为i再加-es.try---tries study---studies cry---cries fly---flies2.不规则变化:be---- is have----has do——does三、一般现在时的句子转换:(1)变一般疑问句:当句子中有be动词或情态动词时,则把be动词或情态动词(can,could 等)提到主语的前面,(口诀:一调二变三问号);I am her sister.---- Are you her sister?She can play chess.----Can she play chess?(2)变否定句:在be动词或情态动词后面直接加not变成否定句. (be后not莫忘记) 例:①陈述句:She is my sister..疑问句→ Is she your sister? Yes, I am./ No, I’m not.否定句→ She is not my sister.②陈述句:I can play soccer.疑问句→ Can you play soccer? Yes, I can./ No, I can’t.否定句→ I can not /can’t play soccer.★注意:对一般疑问句的回答:一般用什么问就用什么来回答。

但以下例外:Is this a pencil? Yes , it is./ No, it isn’t.Is that your backpack? Yes , it is./ No, it isn’t.Are these your parents? Yes, they are./ No, they aren’t.Are those Jim’s brothers? Yes, they are./ No, they aren’t.(3)当句子中没有be动词,也没有情态动词时,变一般疑问句时,在主语前借助动词do (I, we, you,以及复数), does(第三人称单数she,he,it等)变问句;(口诀:一借二变三问号)I like English.----Do you like English?He has three basketball.-----Does he have basketball?(4)变否定句时,在主语后谓语动词前加助动词don’t, doesn’t变成否定句,切记:助动词后的动词则还原成动词原形。

例:①陈述句:We get up(起床) at 7:00 every morning.疑问句→Do you get up at 7:00 every morning?否定句→We don’t get up at 7:00 every morning.②陈述句:She has a brother.疑问句→ Does she have a brother?否定句→ She doesn’t have a brother.※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。
