be 动词、助动词、情态动词讲解（基础篇） 1、 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? ②主语为单数名词或代词时：肯定句：主语+ 动词第三人称单数形式 + 其他+ 。 He watches TV every night. 否定句：主语+ doesn't+动词原形+其他+。 He doesn't watch TV every night. 一般疑问句：Does + 主语+ 动词原形+ 其他+ ？ Does he watch TV every night? Yes, he does. / No, he doesn 't. 特殊疑问句：疑问词+ does + 主语+ 动词原形+ 其他+ ？ How often does he watch TV? ★主语为单数或不可数名词，谓语要用单数第三人称，反过来，看见动词用了单数第三人称，可以推知主语是单数或不可数名词。 ( )1. How __ ______ your dad help at home? A. do B. does C. is ( )2. ______ goes bad easily in summer. A. Milk B Apples C. Cakes ③过去时的句式（当句子时态为过去时时，动词用过去式，不受主语单复数的影响） 肯定句：主语+ 过去式+ 其他+ 。 He / We got up early every morning last year. 否定句：主语+ didn't + 动词原形+ 其他+ 。 He / We didn't get up early every morning last year. 一般疑问句：Did + 主语+ 动词原形+ 其他+ ？ Did he / you get up early every morning last year? Yes, he

小学英语语法：助动词do 的用法 1) 构成一般疑问句，例如： Do you want to pass the CET? 你想通过大学英语测试吗? Did you study German? 你们学过德语吗? 2) do + not 构成否定句，例如： I do not want to be criticized. 我不想挨批评。 He doesn't like to study. 他不想学习。 In the past, many students did not know the importance of English. 过去，好多学生不知道英语的重要性。 3) 构成否定祈使句，例如： Don't go there. 不要去那里。 Don't be so absent-minded. 不要这么心不在焉。 说明：构成否定祈使句只用do，不用did和does。 4) 放在动词原形前，增强该动词的语气，例如： Do come to my birthday party. 一定来参加我的生日宴会。 I did go there. 我确实去那儿了。 I do miss you. 我确实想你。 5) 用于倒装句，例如： Never did I hear of such a thing. 我从未听说过这样的事情。
Only when we begin our college life do we realize the importance of English. 只有在开始大学生活时我们才理解到英语的重要性。 说明：引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。 6) 用作代动词，例如： ---- Do you like Beijing? --你喜欢北京吗? ---- Yes, I do. --是的，喜欢。(do用作代动词，代替like Beijing.) He knows how to drive a car, doesn't he? 他知道如何开车，对吧? 助动词do 的用法是我们精心为大家准备的，希望大家能够多加练习，为以后学好英语打下坚实的基础!

Be动词和助动词用法区别其实be动词也是助动词（auxiliary verbs）。 英语动词大致可分为三种：助动词（auxiliary verbs），情态动词（modal verbs），实意动词（full verbs）。 助动词（auxiliary verbs）：do，be，have。没有实意，“帮助”别的动词，表示时态，否定和提问。情态动词（modal verbs）：can，must，may。也是“帮助”别的动词，但是有自己的实意。实意动词（full verbs）：play，run，think。其他有实意的动词。 be动词可用作助动词（auxiliary verbs）：1，be+Ving：所有的进行时态，如：2，be+过去分词：被动式。 be动词也可用做实意动词（full verbs）：be[bi]v.有；在；是。 你这样想，一个句子里要有动词吧。再看看它们的名字，“be 动词”和“助动词”， 先说“be动词”，（1）这名字里有动词，说明他是动词，句子里有他就不会有别的动词（除非这些动词以别的形式出现，这是后话）了，（2）“am,is,are,was,were”叫be动词，是因为他们是be的不同形式 再说“助动词”，（1）一定要注意“助”，是帮助的意思，说明他不是动词，只是起到了辅助的作用，所以，他们就一定要与动词同时出现。[记住啊，他们离不开动词，但是动词没有他们也是可以的]
（2）did,do,does只是do的不同形式，根据你所需要的时态来选择（1）用于肯定句，否定句和疑问句 am：第一人称单数（即只与I连用），用于现在时（一般现在，现在进行，只要那时态中是现在的就行）eg:①I am a girl.一般现在时②I am eating an apple.现在进行时 ③I am going to do my homework.[be going to表将来，将来中只有这一种] is：第三人称单数，用于现在时（一般现在，现在进行，只要那时态中是现在的就行）(it就不举例了)eg:①She/He is a girl/boy.一般现在时②He/She is eating an apple.现在进行时③He/She is going to do his homework.[be going to表将来，将来中只有这一种] are：第二人称单数，所有人称复数，用于现在时（一般现在，现在进行，只要那时态中是现在的就行）eg:①You are a girl. We/You(你们)/They are girls.一般现在时②You are eating an apple.We/You(你们)/They are eating apples.现在进行时③We/You(你们)/They are going to do our/your/their homework.[be going to表将来，将来中只有这一种] was：第一人称单数，第三人称单数，用于过去时（一般过去，
