Be动词的用法

Be动词的用法 的“be”是个特别动词;有些语言，如中文和马来文，并没有“be”这样的动词。 “Be”除了原形的“be”之外，还有另外七种形式:am, is, are, been, being, was, were. be是一个连系动词，它有自己不同的形式 现在时:be 进行时:being 它的后面必须跟形容词或名词作语，与之构成系表结构，充当句子的谓语。 i am a student主语:i 谓语:am a student(系表结构) being是它的现在进行时态，一般不单独用， 你的工作是什么, what do you do? what is your job? 那么这里选用do和is有什么根据呢, 第一句里面，第二个do是指你做什么，也就是你的工作，就是一个实义动词。按中文说，what you do已经足够了。可是英语里面就不行，必须跟一个助动词，也就是do. 这里就有了一个结论:当句子中有动词时，我们就用助动词do或是does.如果没有动词时，我们就选用is或是are，也就是“Be”除了原形的“be”之外，还有另外七种形式:am, is, are, been, being, was, were. 在句子中，“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb). 例如: 1. The man is a science teacher. 2. Mary's new dresses are colourful. 4. Mother is in the kitchen now. 这四个都是陈述句，可以变成疑问句，方法简单，把主语和“be”或助动词对换位置即可: 5. Is the man a science teacher? 6. Are Mary's new dresses colourful? 8. Is mother in the kitchen now? 当“be”要在祈使句中出现时，它必须借重助动词“do”或“don't”之助，如: 9. Don't be silly! 10. Do be obedient! 11. Don't be a fool! “Be”有两种缩写法，如下: 12. He's not...../He isn't.... 13. You're not...../You aren't... 但“am + not”的缩写法只有一个: 14. I'm not. 谈过了“be”作主动词的功能，现在看看“be”作助动词时，有些什么 用法: 1.“Be + 现在分词”以组成进行式时态(Continuous Tenses)，如: 15. Tony's maid is washing his new car. 16. The children are playing in the field. 17. Samuel was eating when I came in. 18. We have been living here since 1959. 表达进行时态 句型 be + V-ing…(进行时态) 例:What are you reading? (你正在阅读什么,) I am reading a magazine. (我正在阅读杂志。) 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。 be动词 be动词的意思 be动词的用法 例句对照 be动词的意思 be动词意思和用法很多，一般的意思是 “是”，此种用法，有多种变化形式，is，am，are，was，were. 另外，be动词还有成为的意思。 be动词的用法 be (be/is/are/am/was/were) 现在时 I am, you are, he is, we are, you are, they 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), 现在分词 being 英语的“be”是个特殊动词;有些语言，如马来文等，并没有“be”这样的动词。 “Be”除了原形的“be”之外，还有另外七种形式:am, is, are, been, being, was, were. 在句子中，“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb) 例句对照 【当主动词时，“be”在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。例如: 1.

We are students. I am a teacher. Jack was born in 1989. (2)否定句:主语+be动词+not…… 如: My father is not a teacher. 缩写:My father isn’t a teacher. We are not at home. 缩写:We aren’t at home. It is not my book. 缩写:It isn’t my book. I am not a teacher. 注意:现代英语中am not一般不用缩写形式。 (3)疑问句:be动词+主语…… 如:(a) 一般疑问句及其回答: Are you a student? 回答:Yes, I am. No, I am not. Am I right? 回答:Yes, you are. No, you are not. (No, you aren’t.) Is he your friend? 回答:Yes, he is. No, he is not. (No, he isn’t.) Are they on the chair? 回答:Yes, they are. No, they are not. (No, they aren’t.) 注意:含be动词的一般疑问句回答用Yes或No. 其结构是: Yes, + 主语 + be动词 / No, + 主语 + be动词 + not. (b) 特殊疑问句: What is your name? How are you? Where is my pencil-box? 4. There be句型: there be句型是含有be动词的一个重要句型。其结构如下: there + be动词 + 名词 + 地点状语 There is a school there. 那里有一个学校。 在这个句型中a school是真正的主语，be动词的形式由它决定。当这个名词是单数 时，be动词是 当这个名词是复数时，be动词用are There are many students in the classroom. 在教室里有许多学生 there be句型的一般疑问句是将be动词提前，否定句也是将be动词后面加上not, 如: Is there any water in the bottle? 瓶子里有一些水吗, Are there any students in the room? 房间里有学生吗, There isn’t any water in the bottle. 瓶子里没有水。 There aren’t any students in the room. 房间里没有任何学生。 【模拟试题】 一. 用括号中适当的词填空。 1.
