英语一般现在时

1、般现在时第一节 【知识梳理】一、一般现在时的用法：1 、表达经常性或习惯性的动作。2 、表示现在的状态。3 、表示真理或客观事实。例如： 1 、我们经常在操场上踢足球We often play football on the playground.2、他是一个学生。He is a student.3、地球绕着太阳转。The earth goes round the sun.二、一般现在时需要表示经常性的时间状语例如： always 、 usually 、 often 、 sometimes 、 every day 、in the morning/afternoon/evening、 on Su

2、ndays 等。频率副词：always usually often sometimes seldom never总是通常经常有时很少 从不三、 be 动词的一般现在时有三种形式，即：am, is, are （翻译为“是”）1. 如果主语是第一人称I （我）时，be 动词用am。如： I am a student. 我是一名学生。? I am 还可缩写成I'm 。如： I'm David. 我是大卫。am与 not 不能缩写。如：I am not a bad boy.2. 如果主语是you （你，你们）, they （他们，它们，她们）或名词复数（两个以上的人或物）时，be 动词

3、必须用are 。如： Are you twelve? 你是十二岁吗？? Tom and Lily are good friends.汤姆和莉莉是好朋友。? They are at school.?他们在学校。are与主语还可缩写。如：We are= We're ， They are =They're, You are= You're 。而 are 与 not 可缩写成aren't 。 如： They aren't students. 他们不是学生。3. 如果主语是单数名词、不可数名词或第三人称单数代词（he, she, it ）时， be 动词用 is

4、。如 :My mother is a teacher. 我的妈妈是一名老师。? He is a student.他是一名学生。is 也可与主语缩写, 如 : He is = He's, My mother is = My mother's等。但是 This is不可缩写。而is 与 not 可缩写成isn't 。如 :This isn't a book. 这不是一本书。4. 句中含有be 动词的陈述句变一般疑问句。把be动词提到句首，be动词要变大写。注意第一人称变第二人称。回答时用yes或no表示，结构：Yes,主语+be动词，No,主语+be动词+not。如

5、： It is a book. 变为： Is it a book?5. 句中含有be 动词的肯定陈述句变否定句。先找肯定陈述句中的be 动词，在be 动词后加not.如： It is a book. 变为 : It is not a book.根据以上叙述我们可以把动词的用法以口诀的形式表述出来：我（I）用 ami 你（you）用 are , ?is 跟着他（he）,她（she）,它（it） ; ?单数名词用is ，复数名词全用are 。 ?变疑问，往前提，句末问号莫丢弃。?变否定，更容易，？be后not莫忘记。？?？疑问否定任你变，句首大写莫迟疑。三、 There be 句型1、 There

6、 be 的固定句型：There be + 某物 /某人 + 介词 + 某地表示：在某地有某物（或人）2、在there be 句型中，主语是单数，be 动词用 is ;主语是复数，be 动词用 are ;如有几件物品，be 动词根据最靠近be 动词的那个名词决定。3、 there be 句型的否定句在be 动词后加not , 一般疑问句把be 动词调到句首。4、there be 句型与have(has) 的区别there be表示在某地有某物(或人)have(has)表示某人拥有某物第二节【例题精讲】一.选择正确的be动词填空1.
