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。

二、Be动词在一般过去时中的变化： 1． am 和is在一般过去时中变为was。（was not = wasn’t） 2． are在一般过去时中变为were。（were not = weren’t）

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

not，一般疑问句把was或were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was／were；四是疑问句式巧，was／were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, were与not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＋was／were．”；

否定回答用“No,主语＋wasn't／weren'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。）
