一、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 am,is are 都属于be动词，be是他们的原型 be动词的一般现在时有三种形式，即：am, is, are。 1. 如果主语是第一人称I（我）时，be动词用am。 如：I am a student. 我是一名学生。 I am 还可缩写成I'm。如： I'm David. 我是大卫。 2. 如果主语是you （你，你们）, they （他们，它们，她们）或名词复数（两个以上的人或物）时，be动词必须用are。如：Are you twelve? 你是十二岁吗？ Tom and Lily are good friends. 汤姆和莉莉是好朋友。 They are at school. 他们在学校。 are与主语还可缩写。如：We are= We're，They are =They're, You are = You're。而are与not可缩写成aren't。 如：They aren't students. 他们不是学生。但是am与not不能缩写。 3. 如果主语是单数名词、不可数名词或单数第三人称代词（he, she, it）时，be动词用is。 如:My mother is a teacher. 我的妈妈是一名老师。 He is a student. 他是一名学生。 is也可与主语缩写,如: He is = He's, My mother is = My mother's等。但是This is不可缩写。而is与not可缩写成isn't。如:This isn't a book. 这不是一本书。 根据以上叙述我们可以把动词的用法以口诀的形式表述出来： 我（I）是am, 你（you）是are, 剩下is留给她（she）, 他（he）, 它（it）, 两个以上都用are。 be动词am,is,are,如何正确使用它。我用am,你用are,is用于他、她、它。以上主语是单数. 复数主语全用are。指示代词作主语,This,that用is,These,those要用are。若是变为否定句,Not系动词后面加。若变一般疑问句,句首A m,Is,Are,句末问号莫忘加。回答一般疑问句,Yes,或N o简回 do和does的用法 do 这个词（does是第三人称单数形式），大体上从两方面来讲。 1.作为行为动词，跟其他动词一样，如study, play等。他的意思是“做”等。如： We usually do our homework in the afternoon. He does his homework in the evening. 2.作为助动词，也就是帮助主要动词构成否定和疑问等。 We don't like bananas. Do you like apples?

He doesn't like swimming. 上面有一句He does his homework in the evening.要是变成否定句就成了这个样子：He doesn't do his homework in the evening. 这里加上了助动词doesn't，而原来的主动词does变成原形do了。作为助动词的do和does 是没有词义的，它们在句中的构成一般现在时的疑问句和否定句. Do用于主语第一人称，第二人称和第三人称复数形式的句中，does用于主语第三人称单数的句中。Eg. Do you want to be a teacher? 你想成为一个老师吗？Do his friends go to park every day? 他的朋友们每天都去公园吗？I don’t like him. 我不喜欢他。Where does Tom come from? 汤姆来自哪里？I don’t know.我不知道。 He doesn’t live here. 他不住在这儿。will/can/could/would/should/shall 等助动词后面加be 其他时候, 第一人称I后面用am 第二人称, 复数, 用are 单数用is...
