下面做个简要的讲解。 一、be 动词做系动词 1、系动词+表语”的结构 当be 动词做系动词使用时,主要构成“系动词+表语”的结构,在句子中做谓语。
表语可以是名词、形容词、副词、介词短语等。例如: The man is a science teacher. Mary's new dresses are colourful. Mother is in the kitchen now. I have been there before. They shall be here at 10:00 tommorow. That can't be true. You are not being very polite. Your brother is being very annoying this evening 2、be 动词的一般疑问句,方法是把be 移到主语前面,也可说成是移到句首。

Were you at home the day before yesterday? Yes I was. / No I wasn't. Was she late this morning? Yes she was. / No she wasn't.。

连系动词be的用法
I. 概念
连系动词be,在刚开始学英语句子时,恐怕你首先遇到动词王国中的成员就是be。不少同学对be的说法不一,这叫be如何“是”好?连系动词be的基本意思是“是”,其实,不少场合连系动词be也充当“不是”。真可谓“是也不是”。让你先一睹be的“容貌”吧。
(1)询问年龄及回答时be不译出。
—How old are you? 你多大了?
—I'm eleven.我十一岁。
(2)询问姓名与回答时be不译成“是”。
—What's your name? 你叫什么名字?
—My name is Amy. 我叫Amy。
(3)在一些表示问候的用语及答语中be不译出。
—How are you? 你好吗?
—I'm fine. Thank you. 我很好。谢谢。
II. 用法
连系动词be是am, is, are三者的原形,一般不直接出现在句子中,而是以am, is, are的形式出现。它们各有分工,而且随着主语的人称和数的变化而变化。am最专一,始终跟着I转;are 跟you, we及表复数名词或复数意义的词连用;is的交际最广泛,is与“他、她、它”形影不离,至于名词单数,指示代词(this/that)都与is结下不解之缘。
刚开始学习英语的同学,往往对连系动词be与主语人称保持一致的问题把握不好。为此,建议你在歌谣中熟悉连系动词be的“身影”:
我用am,你用are;
is用在他、她、它;
遇到复数全用are。
一般来说,be是当系动词用的,但是当有助动词,比如can could will would shall should,后面就要加原型(和普通的动词差不多),完成事态用been,如have/has/had been
