be动词和therebe句型
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.I am 还可缩写成I'm am 与not 不能缩写。
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?are与主语还可缩写。
如：We're，They're, You're。
而are与not可缩写成aren't3. 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。
如:My mother is a teacher.is也可与主语缩写,如: 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't4. 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。
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.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：我用am，你用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。
There be句型1、There 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。

be 动词的用法
be动词的用法口诀现在时：I am , You are , He / She / It is 。
过去时：I / She / He was。
You / They were。
be 动词+动词（不定式，动名词ing，分词）。
例子： I am good. He is good. You are good.I was doing my homework.They were to go swimming when I saw them.The book was given by my sister.Be 是原形，摇身一变成is, am, are。
下面介绍一则口诀，帮你熟记“动词be的构成”：我(I)用am, 你(you)用are，is连着他(he)，她(she)，它(it)。
单数名词用is，复数名词全用are。
变否定，更容易，be后not加上去。
变疑问，往前提，句末问号莫丢弃。
还有一条须注意，句首大写莫忘记。
改一般疑问句口诀一般疑问句不可怕，先找be动与情动；若有be动或情动，只将be等放句首；若有第一人称词，务必改为二人称；其它部分不用改，注意句末用问号。
若无be动或情动，助动do/does放句首；句中需跟原动词，其他部分同样变。
解释：① be动词：am/is/are；②情态动词：can/may/must；③人称变化：I→you；my→your；we→you；our→your；am→are；does→Does…do; has→Does…have; likes→Does… like.I’m in Class Three, Grade Seven.→Are you in Class Three, Grade Seven ?He watch es TV every day.→Does he watch TV every day?改为否定句口诀变否定很容易，先找be动与情动；若有be动或情动，直加not即可以；若有some变any，其他部分不用动；若无be动或情动，需加don’t、doesn’t；再跟原动才可以，其他部分不解释：原动就是指动词原形，如does→doesn’t do; has→doesn’t have; likes→doesn’t like，此时的do/have/like即原形动词。
