be动词的一般现在时小学英语
be动词的一般现在时有三种形式
be动词的一般现在时有三种形式，即：am, is, are。
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。
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。
但是am与not不能缩写。
3. 如果主语是单数名词、不可数名词或单数第三人称代词（he, she, it）时，be动词用is。
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。
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）是am,你（you）是are,剩下is留给她（she）, 他（he）, 它（it）,两个以上都用are。
英语的be 动词是个用法比较复杂的动词。
复杂的原因有两点：1、除了原形的be 之外，对于不同人称代词以及单数名词和复数名词，be 会有各种变化形式和缩写形式。

be动词在一般现在时中的变化
be动词在一般现在时中的变化
1.句子:Hello! I'm Lucy.
你好!我是露西。
这句是be动词的一般现在时，结构是:主语+be动词+其他，主要表示存在的状态。
句中I'm是 I am 的缩写形式。
2.be动词在一般现在时中有三种变化形式，即am、is、are。
它们分别对应不一样的主语。
①人称:I ， be动词:am
②人称:you (你) ， be 动词:are
③人称:he , be动词:is
④人称:she ，be动词:is
⑤人称:it ， be动词:is
⑥人称:we ， be动词:are
⑦人称:you(你们) ， be动词:are
⑧人称:they ， be动词:are
一般现在时be动词变化规侓如下四句话：
我用am,（当句子的主语是第一人称单数时,be动词用am）
你用are,（当句子的主语是第二人称单数时,be动词用are）
is用于他它它,(当句子的主语是第三人称单数时,be动词用is）
复数全用are.（当句子的主语是各种称复数时,be动词全用are）掌握这个知识点关键是把握句子主语的人称和数.

二. 实义动词的一般现在时
1、什么叫实义动词？
实义动词是指表示有具体意思的动词, 也叫行为动词。 如: like(喜欢）, eat（吃）, live（居住）, have（有）, run（跑） 等等。 实义动词占英语中动词的绝大多数。
我们已学过的be 动词可译成“是”，
有时译成“成为”，有时则没有具体意 思如： “She is tall.”这句译成： “她很 高”。故be 动词不属于实义动词。
2、一般现在时实义动词作谓语的时侯有两种形式：
1. 动词原形；如: enjoy 2. 第三人称单数动词形式；如: enjoys
主语 +
How do you spell it? 特殊疑问句: 疑问词+一般疑问句 How does he spell it?
直接回答，而不用yes 或no.

英语句子中什么时候用be动词
•英语句子中什么时候用be动词一：用be动词的一般现在时有三种形式，即：am, is, are。
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。
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。
但是am与not不能缩写。
3. 如果主语是单数名词、不可数名词或单数第三人称代词（he, she, it）时，be动词用is。
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。
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）是am,你（you）是are,剩下is留给她（she）, 他（he）, 它（it）,两个以上都用are。
二：作为助动词的do和does是没有词义的，它们在句中的构成一般现在时的疑问句和否定句。
Do主要用于第一，二人称，和第三人称复数如I，We，they，you，等。
小学英语be动词用法详解及练习
小学英语be动词用法详解及练习{ be动词的用法}语法专题详解1、be动词包括am,is,are三个词。
2、Am、is、are这三个词常在一般现在时中出现，我们可以将其用法归纳如下：am、is用于主语表单数概念的句中（主语是you除外）。
第一人称单数I配合am来用，常见句型“I am+…”；第三人称单数He、She 、It配合is使用，常见句型“She/He/It is +…”如：I am ten years old.I am a boy.She is a good girl.He is so thin.It is a dog. 它是一只狗。
Are主要用于主语表复数概念的句中Are主要用于主语表复数概念的句中（包括一些简单集体名词，如：people，family），第二人称(You)配合are使用，常见句型：“You are+…”如：You are great.Amy and Mary are sisters.苏海和苏洋是姐妹。
The family are all at home.全家人都在家。
There are many apples on the tree. 树上有很多苹果。
代词you是一个单复数同形词，既可表示“你”，又可表示“你们”，所以避免混淆，总是跟are 做朋友。
注意：含有be动词的句子的否定是在把not放在be动词的后面。
如：I am not a student. 我不是学生。
The cat isn’t white.这只猫不是白色的。
They aren’t students.他们不是学生。
常见的简缩形式的变法1、简缩形式的变法：把倒数第二个字母，通常是元音字母变成' 但are除外，are要把a打成' 。
Eg:I am=I’m he is=he's they are=they'reshe is=she’s we are=we’re it is=it’s2、简缩形式和完全形式的汉语意思相同。

疑问句：Are they fruit? 它们是水果吗? （主语和谓语倒装意思是主语和谓语调换位置）肯定句：The book is on the table.书在桌子上。

就表语提问时，则以一个疑问代词或疑问副词开头，之后是“be动词+ 主语...”（am，is，are的第一个字母无需大写），在句尾加问号；这种语序是主语和谓语倒装语序。
