1、精选优质文档-倾情为你奉上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
2、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。（wasnot=wasnt）2 are在一般过去时中变为were。（werenot=werent）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wa
3、s，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
4、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wasnt, werent。即： 主语 wasnt werent 表语 其他。例如： I was not (wasnt) here yesterday 昨天我不在这儿。 My parents were not (werent) 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
5、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wasntwerent”。 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 werent) 是的，她们在。（不，她们不在。）练习题一、 Be动词的一般现在时练习1 用be
