Be动词的用法

一、be动词包括“am”, “is”, “are”三种形式。

1. 第一人称单数(I)配合am来用。句型解析析:I am+… 2. 第二人称(You)配合are使用。句型解析:You are+…

3. 第三人称单数(He or She or It)配合is使用。句型解析:She(He, It) is +… 4. 人称复数 (we /you/they)配合are使用。句型解析:We (You, They) are +…

be动词前面的人称,是不可随意替换的。

例如:I am, You are, She is,并不会出现I is, You am, She are 这样的情形。 请记住以下口诀:

我用am,你用areis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,benot莫忘记。 疑问否定任你变,句首大写莫迟疑。

二、Be动词在一般过去时中的变化: 1 am is在一般过去时中变为waswas not = wasn’t 2 are在一般过去时中变为werewere not = weren’t

3 带有waswere的句子,其否定、疑问的变化和am, is, are一样,即否定句在waswere后加

not,一般疑问句把waswere调到句首 be的过去时有四巧:

一是时间状语巧, 表示过去的短语要记牢; 二是形式巧,单数was,复数were

三巧是否定句结构,not紧跟waswere 四是疑问句式巧,waswere向前跑(提前)

【一巧】时间状语(即标志词)巧。一般过去时表示过去发生的动作或存在的状态,恰巧 与表示过去的一些时间状语连用。

【二巧】形式巧。它与一般现在时一样,形式多样:当主语是第一人称单数或第三人称单 数时,谓语动词用was;主语是第二人称或其他人称复数时,谓语动词用were 例如: I was in the classroom yesterday morning 昨天早上我在教室里。 He was at school last Tuesday 上周二他在学校。

They were over there a moment ago 刚才他们在那边。

【三巧】否定句结构巧。与动词be的一般现在时一样,它在动词后面加not即可变成否定 句,并且was, werenot可以缩写成wasn't, weren't。即: 主语 wasn't weren't 表语 其他。例如:

I was not (wasn't) here yesterday 昨天我不在这儿。

My parents were not (weren't) at home last Sunday 上周日我父母不在家。 【四巧】 疑问句式巧。把was, were提到句首,句末用问号即可变为一般疑问句。即: Was(Were) 主语 +表语 其他?这恰巧与动词be的一般现在时的疑问句 式相似。例如: Were you at home the day before yesterday 前天你在家吗? Was she late this morning﹖今天早上她迟到了吗? 更巧的是疑问句的答语也相似,肯定回答用“Yes, 主语+waswere

否定回答用“No,主语+wasn'tweren't

例如:Were Wei Hua and Han Mei here just now 刚才魏华和韩梅在这儿吗? Yes, they were (No, they weren't) 是的,她们在。(不,她们不在。
