关于be动词、情态动词和实义动词的区别
关于be动词、情态动词和实义动词的区别 到目前为止，我们主要学习了三类动词：be动词、情态动词和实义动词。下面我们分别来讲一下它们得用法。 1.be动词属于系动词, 在句子中主要表现为三种形式：am is、are。 后面往往接形容词或名词做表语。如： (1)I’m young. (young形容词做表语) (2)He is a boy.( a boy名词做表语) 含有be动词的句子在进行否定、疑问句变化时，都要在be动词上变化。 (1)变为否定句：主语+be+ not+其他。即，直接在be后not. ①I’m a Chinese boy.(变为否定句) ②You are good. (变为否定句) ③He is strict with us. (变为否定句) ④She is from America. (变为否定句) 以上四个句子中都含有am、is或are，变否定句时，直接在am 、is、are后面加上not.即： ①I’m not a Chinese boy. ②You are not good. ③He is not strict with us. ④She is not from America. (2)变为一般疑问句：Be+主语+其他？即把be动词提到主语的前面。注意：当肯定句主语为第一人称I和We时，变一般疑问句要变为第
二人称，be动词也要相应的变为are.同样肯定句中的my和our 也要变为your. ①I am a boy. (变为一般疑问句) →Are you a student? ②We are good friends. (变为一般疑问句) →Are you good friends? ③She is from America. (变为一般疑问句) →Is she from America? ④He is strict with us. (变为一般疑问句) →Is he strict with us? (3)变特殊疑问句：一般的要求为“对划线部分提问”，即用特殊疑问词代替划线的部分，后接省略划线部分的一般疑问句（一般不再出现划线部分）。如： ①I’m well.（对划线部分提问） →How are you? ②She is from America. （对划线部分提问） →Where is she from? 2.关于情态动词：初中我们常用的情态动词主要有：can、 may、 must、need。我们这里主要以can为例来说明情态动词的用法。 情态动词后面必须接动词的原形。情态动词can的用法类似于be动词。不论主语为第几人称，变否定就是在can后加not.变

be动词、助动词、情态动词讲解(基础篇)Microsoft Word 文档
be动词、助动词、情态动词讲解 (基础篇) 1、be动词的用法。 英语中，be动词选用单数还是复数，要由主语来定，主语是单数，就用单数，反之用复数。 ◆句中含有be动词时： 肯定句：主语＋be ＋其他 否定句：主语＋ be ＋ not ＋其他 一般疑问句： Be ＋主语＋其他＋？ 特殊疑问句：疑问词（what / who / when / where）＋ be ＋主语＋其他＋？ I am a teacher. You are right. She is 16 years old. My father is at home. The students are playing games. My teacher was ill yesterday. There is a picture on the wall. There are two books on the table. ★ be动词用法歌： 我用am，你用are，is 连接他她它。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动词作谓语，它后面一般跟名词、形容词或介词短语。 她个子很高。她在教室里。 她是一个高个子的女孩。 2、助动词的用法。 英语句子按正常语序是“什么人或事物” + “做什么”，即，我们常说的“主语 + 谓语 + 其他”。 ①主语为I 或复数名词、代词时： 肯定句： I / We / They / The students ＋动词原形＋其他＋。 We watch TV every night. 变否定：主语＋ don’t ＋动词原形＋其他＋。 We don’t watch TV every night. 一般疑问句 Do + 主语 + 动词原形 + 其他 + ？ Do you watch TV every night? Yes, we do. / No, we don’t. 特殊疑问句：疑问词 + do + 主语 + 动词原形 + 其他 + ？ How often do you watch TV?
