第四章 一般现在时态
一、一般现在时的定义
一般现在时是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的时态。
二、一般现在时的结构
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。现在以连系动词be 和行为动词read为例，对一般现在时的肯定句、否定句、疑问句及其简略答语的构成以表格形式加以说明：
动词肯定句否定句
beI am …I am not …
You/We/They are …You/We/They are not …
He/She/It is ...He/She/It is not …
readI/We/You/They read…I/We/You/They/ do not read …
He/She/It reads …He/She/It does not read …
动词疑问句简略答语(肯定)简略答语(否定)
beAm I …?Yes ， you are.No， you are not.
Are you …?Yes， I am/we are.No， I am/we are not.
Are we …?Yes， we/you are.No， we/ you are not.
Are they …?Yes， they are.No， they are not.
Is he…?Yes， he is.No， he is not.
Is she …?Yes， she is.No， she is not.
Is it …?Yes， it is.No， it is not.
readDo I / we / they read …?Yes， you / we / they do.No， you / we / they do not.
Does he / she / it read … ?Yes， he / she / it does.No， he / she / it does not.
连系动词be 的各种形式常与代词或not缩写成一个词。助动词do，does 一般只有与not 缩写。联系动词be缩写形式如下
肯定缩写否定缩写
I amI’mI am notI’m not
You areYou’reYou are notYou’re not /You aren’t
He isHe’sHe is notHe’s not /He isn’t
She isShe’sShe is notShe’s not /She isn’t
It isIt’sIt is notIt’s not / It isn’t
We areWe’reWe are notWe’re not / We aren’t
They areThey’reThey are notThey’re not / They aren’t
动词do not 的缩写形式为don’t，does not 的缩写形式为doesn’t。
二、 动词加-s 或-es (动词第三人称单数)
当主语是第三人称单数时，谓语动词需加-s 或-es
1. 一般在词尾加 –s
例：work—works leave --- leaves swim --- swims
2. 以字母s，x，ch，sh 或o结尾的词加-es
例：pass--- passes fix ---fixes teach --- teaches do--- does
3. 以辅音字母加y结尾的词，先变y为i再加-es
例：study --- studies carry --- carries fly --- flies cry --- cries
三、 一般现在时的用法
1. 表示经常或习惯性的动作。常与often(经常)， always(总是)， sometimes(有时)， every day(每天)， on Sundays/Mondays 等表示频度的时间状语连用。
一般现在时的时间状语有：today， often， sometimes， always， usually， every day ( week， month， year，…) ， this year， once a week ( month， year，…) 一周(月，年)一次
例句：I get up at 6 o’clock every day.
He often goes to school by bike.
2. 表示客观事实，普遍真理。
例句：Two and two are four.二加二等于四。
The earth moves around the sun.地球绕着太阳转。
