2018初中英语语法之Be动词定义及用法
2018初中英语语法之Be动词定义及用法 Be动词定义及用法 1.Be动词有三个，am,is还有are.我用am,你用are,is跟着他她它，复数全部都用are. 如果遇到过去时，was来把am,is替，were来把换掉动词are 2.do和be动词的用法区别 Be动词就是(am，are,is)..句子中如果没有实意动词(例如:write，buy)之类的动词，就直接在主语后面加Be动词。而如果是句子中有实意动词，那么如果你要改为一般疑问句，就要借助DO(do 也称为助动词)，例如:I study. 改为一般疑问句:Do you study? 顺口溜：be氏三朵花,am,is还有are, 我(I)恋am,你(you)恋are, is跟了他(he)她(she)它(it), 单娶is,复娶are。 详细讲解： 英语的be动词是个用法比较复杂的动词。复杂的原因有两点： 1、除了原形的be之外，对于不同人称代词以及单数名词
和复数名词，be会有各种变化形式和缩写形式。概括一下有七种形式：be,am,is,are,was,were,been,being。它们与人称代词和名词单、复数的搭配关系是： 现在时I am,you are,he/she/it/is,we/you/they are;名词单数、不可数名词用is，复数用are。 缩略式I\\\m,you\\\re,he\\\s,we\\\re,you\\\re,they\\\re 否定缩略式I\\\m not,isn\\\t,aren\\\t 过去时I was,you were,he/she/it/was,we/you/they were;名词单数、不可数名词用was，复数用were。 否定缩略式wasn\\\t,weren\\\t 过去分词been 现在分词being 2、在句子中，be有两种主要作用：一是作为系动词(The Linking Verb)，本身可以作用谓语动词;二是做为助动词(The Auxiliary Verb)，与谓语动词一起构成各种时态和被动语态等。

高考英语语法填空专项训练动词的时态语态综合练习
语法填空专项训练---时态语态 解题技巧 在高考英语语法填空中，一般有一空是考查谓语动词的时态，同时有一空是考查非谓语动词，因此，首先要判断括号中所给动词是谓语动词还是非谓语动词；若是谓语动词，一是根据主语与谓语动词的关系判断用主动语态还是用被动语态，二是根据具体的语境来判断用哪一种时态，进而确定所填动词的形式。 例1：This proverb is saying we have to let things go in their natural course. Being too anxious to help an event develop often 40 (result) in the contrary to our intention. (2008广东) 分析：因句中Being too anxious to help an event develop是动名词短语作主语，括号中的result应当为谓语动词；主语与谓语动词是主动关系，再说短语动词result in本身是不能用于被动语态的，故用主动语态；根据语境，这段话是拔苗助长这个成语故事所说明的道理，“我们必须让事物沿着它们的自然进程发展。太着急帮助一件事物发展，结果往往和我们的意图相反（欲速则不达）。”这是客观真理，应当用一般现在时，主语是第三人称单数，故填results。 例2：The policeman’s attention was suddenly caught by a small box which __________ (place) under the Minister’s car. (2005广东) 分析：替代the box的关系代词which在定语从句中作主语，place应当为谓语动词；因主语which (the box)与place (放置)是被动关系，故用被动语态；又因place这个动作发生在was caught这个动作之前，即“过去的过去”，用过去完成时的被动语态，故填had been placed。 一、单句填空：用所给动词的适当形式填空。 1. The house belongs to my aunt but she ____________ (not live) here any more. (全国I)

(完整版)be动词用法和练习题
Be 动词专项练习 be动词的一般现在时有三种形式，即：am, is, are（翻译为“是”，“在”） 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。 am 与not 不能缩写。如：I am not a bad boy. 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。 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。 4. 句中含有be动词的陈述句变一般疑问句。 把be动词提到句首，be动词要变大写。注意第一人称变第二人称。回答时用yes或no表示，结构：Yes, 主语+be动词，No，主语+be动词+not。 如：It is a book. 变为：Is it a book? 5. 句中含有be动词的肯定陈述句变否定句。 先找肯定陈述句中的be动词，在be动词后加not. 如：It is a book. 变为: It is not a book. 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)用am，你(you)用are， is连着他(he)，她(she)，它(it)； 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。
