be动词的问题
看了一个英语视频,关于主系表的,里面说,没有动作的句子就用be动词,可是我觉得,没有动作的句子所有的系动词都可以用啊又不止be动词,帮我详细解答一下,怎么理解对,在句子中没有“是”的意思什么情况下用be动词呢?be是一个多功能动词,现将它的用法归纳如下:
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)
帮助动物就是帮助人类。
The twins were very busy yesterday.(一般过去时)
这对双胞胎昨天很忙。
It will be sunny tomorrow.(一般将来时)
明天天气晴朗。
She has been ill for over a week.(现在完成时)
她已经病了一个星期多了。
【注意】有以下三类系动词:
1. “存在”类:表示存在或具有某种特征或状态,这类连系动词强调“存在”。常见的有:be(是),look(看起来),feel(摸上去),seem(似乎是),appear(似乎、显得),prove(证明是),smell(闻起来)taste(尝起来),sound(听起来)等。如:
The story sounds beautiful. 这故事听起来很动听。
Those oranges taste good. 这些桔子尝起来很好。
2. “持续”类:表示某种情况或状态的持续。这类连系动词强调“持续”。常见的有:remain(依然),keep(保持),stay(保持),continue(继续、仍旧),stand(处于某状况或情形)等。如:
Why don't you put the meat in the fridge? It will stay fresh for several days.
你为什么不把肉放到冰箱里呢?它将会保鲜几天。
Please keep quiet in the reading room. 阅览室里请保持安静。
3. “变化”类:表示由一种情况或状态变化成另一种情况或状态。这类连系动词强调“变化”后的情况或状态。常见的有:become(变成),turn(变成),grow(变得), go(变得)等。如:
Put the fish in the fridge, or it will go bad in hot weather.
在热天,把鱼放到冰箱里,否则它要变坏的。
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.
女孩子们现在正在朗读、抄写新单词。
Young Tom was having an English class at this time yesterday morning.
小汤姆昨天这个时候正在上英语课。
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)
我们家乡种茶叶。
This building was built three years ago.(一般过去时的被动语态)
这幢楼是三年前造的。
Our classroom has been cleaned and tidied already.(现在完成时的被动语态)
我们的教室已经打扫、整理过了。
How could this kind of cakes be made in your home?(含情态动词的被动语态)
这种蛋糕怎么能在你家里制作呢?
That is a day never to be forgotten.(动词不定式的被动语态)
那是永远无法忘记的一天。
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.
明天我们将到公园里去种树。
I didn't know if she was going to come here.
我不知道她是否到这里来。
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.
这家新店将要到下周一才开业。
One night an angel came to Mary and told her that she was to have this special boy.
一天晚上,一个天使到玛丽那里并告诉她将诞生一个特殊的婴儿。
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.
哦,真酷!三亚有许多可看的东西,那儿甚至有一个鹿园。
There are about 80 goats on the top of the hill.
山顶上大约有八十只山羊。
Will there be a football match in your school next week?
下周你们学校将有一场足球赛吗?
四、实义动词be
Be可以视为实义动词,因为它具有实际的词义,如“成为;做;发生;举行;逗留;到达”等。如:
I am a student now. (be+名词)
我现在是一个学生了。
This small bag is red. (be+形容词)
这个小小的包是红色的。
My little daughter was seven years old last year. (be+数词)

My dream is to be a doctor. (be+不定式短语)
我的梦想是成为一名医生。
My dream is that I can be a doctor. (be+表语从句)
我的梦想是我能成为一名医生。

关于STAY,REMAIN和KEEP用法的一些区别
一、在表示“继续呆在某处”时,应用remain或stay,
两者可以互换,
它们都是不及物动词。如:
Shall
I
go
or
stay?
Stay
indoors
for
a

二、表示“住在某处”时,只能用stay,
stay作不及物动词用。如:

Hilton
Hotel.
My
mother-in-law
is
staying

week.
三.表示“暂住、短期停留”时,只能用不及物动词stay。如:
我下了keep健身,但是没有瑜伽垫,应该用什么代替?我现在用床垫铺在床上,出汗也不管就扔在柜子里,
强调句型的be动词可以换成seem,keep等动词吗
要强调句子的某一部分(通常是主语、状语、宾语),可以把it当做先行词。这种强调句的结构是:It is(was)+被强调部分(主语、宾语或状语)+that (who)+句子其余部分"。
如果被强调部分指人时,用who或whom;指事物时用that,that也可以指人。
例句:
It was in 2021 that I worked in a factory. (强调状语)
It was in Shanghai that I saw the film. (强调状语)
It is English that Mr. Li teaches us. (强调宾语)
It is Mr. Li who teaches us English. (强调主语)
