be动词的用法总结及练习题

be 动词的用法篇一 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(amam，are,is)..句子中如果没有实意动词(am例如:writewrite，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(amdo 也称为助动词)，例如:writeI study). 改为一般疑问句:writeDo y)ou study) ? 顺口溜：be 氏三朵花, am, is 还有 are, 我(amI)恋 am, 你(amy)ou)恋 are, is 跟了他(amhe)她(amshe)它(amit), 单娶 is, 复娶 are。 be 动词的用法篇二 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, y)ou are, he/she/it/ is, we/y)ou/they) are;名词单数、不可数 名词用 is，复数用 are。 缩略式 I'm, y)ou're, he's, we're, y)ou're, they)'re 否定缩略式 I'm not, isn't, aren't 过去时 I was, y)ou were, he/she/it/ was, we/y)ou/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 (amThe Linking Verb)，本身可以作用谓语动词;二是做为助动词(amThe Auxiliary) Verb)，与谓 语动词一起构成各种时态和被动语态等。 下面做个简要的讲解。 be 动词的用法：做系动词 1、系动词+表语”的结构 当 be 动词做系动词使用时，主要构成“系动词 +表语”的结构，在句子中 做谓语。表语可以是名词、形容词、副词、介词短语等。例如： The man is a science teacher. Mary)'s new dresses are colourful. Mother is in the kitchen now. I have been there before. They) shall be here at 10:write00 tommorow. That can't be true. You are not being very) polite. Your brother is being very) annoy)ing this evening 2、be 动词的一般疑问句，方法是把 be 移到主语前面，也可说成是移 到句首。 Is the man a science teacher? Yes, he is. / No, he isn't. Are Mary)'s new dresses colourful? Yes, they) are. / No, they) aren't. Was mother in the kitchen then? Yes, she was. / No, she wasn't. Were y)ou at home the day) before y)esterday)? Yes, I was. / No, I wasn't. Was she late this morning? Yes, she was. / No, she wasn't. 3、be 动词用在特殊疑问句 在特殊疑问句里，be 动词仍然移到主语前面，但特殊疑问句是以特殊 疑问词开头的，所以 be 动词只能说是移到主语前面，或者说是在特殊疑问 词的后面。例如： Whose bike is broken? Xiao Ming's bike is. Who was singing in the room? Mr. Zhang was. Where are y)ou from? I am from Wuhu. What class were y)ou in? We were in Class 2. How old is Tom? He is ten. 4、be 动词的否定句 be 动词做谓语时，它的否定形式是在 be 后加 not，并且可以缩写。例 如： It is not sunny) today). Tom and his friends are not in the park. You were not nine y)ears old when I went to the university). He was not often late for his class when he was a student. I wasn't here y)esterday). My) parents weren't at home last Sunday). 5、be 动词的祈使句 be 动词的祈使句有肯定和否定两种形式。肯定形式是以 be 动词开头， 而否定形式或强调句形，要加 don't 或 do。例如： Be careful! Be a good boy)! Don't be silly)! Don't be a fool! Do be obedient! Do be careful. be 动词的用法：做助动词 助动词 be 有两个基本用法，一是与谓语动词一起构成各种时态，二是 构成被动语态。 1、“be + 现在分词组”成各种进行式时态。例如：”成各种进行式时态。例如： Tony)'s maid is washing his new car. The children are play)ing in the field. Samuel was eating when I came in. We have been living here since 1959. This time next day) they) will be sitting in the cinema.
