be动词的用法总结 Be动词的用法口诀 : 我用am，你用are，is连着他，她，它；
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
一、系动词be
be可以用作连系动词，中心词义是“是”，句型为“主＋系＋表”结构。be的形式常用am, is, are(现在式)；was, were(过去式)；will/can/may/must be(助动词/情态动词＋原形)；have/has/had been(助动词＋过去分词)等。如：
To help animals is helping people.（一般现在时）
The twins were very busy yesterday.（一般过去时）
It will be sunny tomorrow.（一般将来时）
She has been ill for over a week.（现在完成时）
二、助动词be
Be可以用作助动词，无词义，辅助主要动词一起在句中作谓语动词。用法如下：
1.be+doing：构成进行时态，有现在和过去两种进行时态。如：
The girls is reading and copying the new words now.Young Tom was having an English cla at this time yesterday morning.2.be+done：构成被动语态（主语是动作的承受者，done必须是及物动词）。如： Tea is grown in my hometown.（一般现在时的被动语态）
This building was built three years ago.（一般过去时的被动语态）
Our claroom has been cleaned and tidied already.（现在完成时的被动语态）
How could this kind of cakes be made in your home?（含情态动词的被动语态）
That is a day never to be forgotten.（动词不定式的被动语态）
3.be+going to do，表示“打算或将要做某事”，be有现在和过去两种形式。如：
We are going to plant trees in the park tomorrow.I didn't know if she was going to come here.4.be+to do，表示“按计划安排将要做某事”。如：
The new shop is not to be opened till next Monday.【练习】翻译下列句子
1.他们现在正在开会。They
a meeting now.2.如今英语越来越重要了。English
more and more important these days.3.窗户是汤姆打碎的。The window

a meeting at this time yesterday.8.明天我们将到公园里去种树吗？ we

三、there be句型
be可以用在there be 句型中。there be句式为：there be+主语部分＋状语部分，表示“某处存在某物”，有现在时、过去时和将来时等时态。如： Oh, cool!And there are many things to see.There is even a deer park in Sanya.There are about 80 goats on the top of the hill.Will there be a football match in your school next week? 【练习】用there be句型的适当形式填空
1.There

a robot（机器人）in your factory in the near future（不久的将来）? 8.There

Be可以视为实义动词，因为它具有实际的词义，如“成为；举行；到达”等。如：
