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，

Are they American?——Yes, they are. /No, they aren’t. 表示疑问，一般回答只有两种可能Yes或No，句中没有疑问词。 如何将一个肯定的陈述句改为否定句： 1、看句中有无be动词，如有，把be动词提到句首即可。 2、看句中有无情态动词，如有，把情态动词提到句首即可。 3、如上述二者都没有，就应把助动提到句首。分四个步骤： （1）肯定陈述句中本来是没有助动词的，要加上去，位置在主语（某人/某物）后，动词前。 （2）确定助动词用do、does还是did，根据句中动词，动词是原形的助动词就用do，动词是第三人称单数的助动词就用does，动词用过去式的助动词就有did。
（3）把助动词后提到句首。 （4）原句中动词假如发生变化就要恢复成原形。 有some的要考虑是否要用any 2.助动词（do/does/did） 主语助动词（原形）助动词（过去式）否定形式I/We/you/they do did don’t/didn’t He/she/it does did doesn’t/didn’t ①.Do+非第三人称单数＋动词原形…? do/don't you/they have...?—Yes, I do/No, I don’t. ②.Does+第三人称单数＋动词原形…? does/doesn't he/she have...?—Yes, he does./No, he doesn’t. ③Did+所有主格＋动词原形…? did/didn't you/he/she/they go to school?—Yes, i did./No, I didn’t. 3.特殊疑问句 表示疑问，有疑问词开头，回答有很多种可能。常用疑问词：What、Who、When、Which、Why、Whose、How ※What do you/they/we…+动词原形？I/They/We+动词原形… What does he/she/it…He/She/It +(动词＋S)….

Be动词和助动词的用法区别 1、be动词的用法。 be am / is are 现在时 was were 过去时 单数复数 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。 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+ ？
