be是英语动词中比较特殊的一类动词，其使用频率很高，牵涉到各种句型、时态和语态等用法，下面小编告诉你高中英语be动词的用法，大家一起来看看吧!
高中英语be动词的用法:
一、助动词be
作为助动词，be没有具体含义，而是与主要动词一起构成句子的谓语动词。这种情况下，be主要用来构成进行时和被动语态。
(一)进行时态中的be
此时，be可以与主要动词的现在分词一起，构成各种进行时态。如:
He is reading in the library now. (现在进行时)
She wasswimming in the river this time yesterday. (过去进行时)
They will be arriving in Beijing tomorrow. (将来进行时)
We have been learning English for ten years. (现在完成进行时)
(二)被动语态中的be
助动词be能够与主要动词的过去分词一起构成被动语态，即be done结构。如:
Chinese iswidely used around the world nowadays.
The window wasbroken by the naughty boy just now.
Your watch has already beenrepaired.
【注意】
助动词be能够构成特殊句型。如:
1、be going to do
be going to do表示“打算或将要”。如:
He isgoing to visit us next week.
It isgoing to rain soon.
2、be about to do
be about to do表示“刚要，即将”。与be going to do表“将要”不同的是，be about to do表示的是说完话后马上就要去做或是短期内马上就要去做。如:
The plane isabout to take off in five minutes' time.
3、be to do
be to do表示“按计划要做”。如:
One night an angel came to Mary and told her that she wasto have this special boy.
The new store isto be opened tomorrow.

二、特殊句型中的be
(一)There be句型
与上面用法都不同的是，be可以与there一起构成there be句型，用来表示存在。考虑到There be句型较为重要，内容较多，在此不做赘述，后面再找时间跟大家单独分享。今天就先给几个常见的例句。
There is a white ruler on the desk.
There were a great many people in the car race last year.
(二)祈使句中的be
这种情况下，句子一般以Be开头或是Don't be开头，表示命令或建议等。如:
Bepatient! (耐心点!)
Don't be so hard on me! (不要对我们这么严厉!)
(三)虚拟语气中的be
be有时可以放在句首，引起虚拟语气。如:
Be he rich or poor, she will marry him.
Be it true or not, she will see it herself.
此时的be引导的句子其实相当于一个让步状语从句。以上两句话就相当于:
Whether he be rich or poor, she will marry him. (无论他是否有钱，她都会嫁给她。)
Whether it be true or not, she will see it herself. (无论这是否是真的，她都会亲自去见证。)
there be结构的be的活用:
■there be 结构中的be必须随着be后面名词的数及句子后面的时间，使用不同的形式或时态。如:
(1) There are fifty chairs, desks and a blackboard in our classroom. 我们的教室里有五十把椅子、五十张课桌和一块黑板。
(比较) There is a blackboard, fifty chairs and desks in our classroom. 我们教室里有一块黑板、五十把椅子和五十张课桌。
(2) There weren’t any high buildings in the village twenty years ago. 二十年前，村子里没有高楼大厦。

■there be结构可与情态动词can, could, will, would, must, may, might, ought to 及某些不及物动词seem, appear, happen等连用，如:
(1) Do go into the hole, for there can be snakes in it. 不要进到洞里面去，因为洞里可能有蛇。
(2) The car doesn’t run. There must be something wrong with it. 车不走了，肯定出了毛病。
(3) There seemed to be some people in the room, for the water is still hot. 房间里原来似乎有人，因为水还是热的。
(4) There happened to be a policeman there. 碰巧那儿有个警察。
■有时为了使句子表达生动，动词be 可换成 come, live, remain, stand, lie, appear, exist, seem, remain, …. 。如:
(1) Long ago, there lived a king who loved horses very much. 很久以前，有个非常喜欢马的国王。
(2) There stands a house on the top of the mountain. 山顶上有座房子。
(3) There exists some doubt in what he said. 在他所的话中有些疑点。
■there be 结构不能跟 have(有) 连用，但可跟 have / has + 过去分词，或 have /has to + be / stand / lie 等动词原形等连用。如:
(1) The man liked to plant trees, and soon there have been tall trees around his house. 那个人喜欢种树，不久他房子的周围就有了很多大树。
(2) There has to be air and water on the planet for living things to live on. 在那颗行星上必须要有能使生物生存的空气和水。
there being 结构用法解说:
there being 为 there be 结构的非谓语形式，主要有两种用法，一是用作状语，二是用作介词宾语。
1. 用作状语
there being 结构最主要的功能是用作状语。如:
There being nothing else to do, we went home. 没有别的事可做，我们就回家了。
There being no taxi available, he had to walk home. 由于没有计程车可搭，他只好步行回家。
这类结构有时可与状语从句转换。如:
There being no further business, I declare the meeting closed.=As there is no further business, I declare the meeting closed. 由于没有再要讨论的事了，我宣布散会。
2. 用作介词宾语
there being 结构还可用作介词宾语。如:
They planned on there being another meeting. 他们打算再开一次会。
There is now some hope of there being a settlement of the dispute. 现在还有点希望可以解决这次争端。
注意，there being 用作宾语时，不能用作动词的宾语，只能用作介词的宾语，并且这个介词不能是 for
there to be 结构用法详解:
there to be 为 there be 结构的非谓语形式，有两种主要用法，一是用作动词的宾语，二是用作介词 for 的宾语。
1. 用作动词的宾语
可接该结构作宾语的动词不多，常见的有like, prefer, hate, want, mean, intend, expect, consider 等。如:
I don't want there to be any misunderstanding. 我可不希望有任何误解。
Students hate there to be too much homework. 学生讨厌做太多的家庭作业。
I expect there to be a big response to our advertisement. 我预料我们的广告会有很大的反响。
注意，在 let there be 结构中，动词 be 不带 to。如:

2. 用作介词for的宾语
用作介词宾语一般用 there being，但用作介词 for 的宾语时，要用 there to be。如:
