第三篇：be动词与助动词的用法
be动词与助动词的用法
1.陈述句:be动词第一人称用am,第二人称用are,第三人称单数用is复数用are.助动词do一般省略,直接用动词,注意动词时态和人称变化.有时在动词前加do,表示强调,加强语气.如:Do be quiet!
2.疑问句:be动词直接提前,其他部分不变(由陈述句转变).助动词do同样,由省略直接提前放置,后面动词不变,注意do的时态和人称变化.3.否定句:be动词和助动词do后面加not.be作助动词用的形式如下： ①am, is, are, was, were ②助动词+be：shall be, will be, can be, etc.③have/has/had + been（完成时）④am, is, …being（进行时）
（1）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。）
例：He will be taking a walk in the park at this time tomorrow morning.（明天早晨此时他将会正在公园散步。）
例：She has been teaching English in our school for years.（她已在我们学校教英语许多年了。）
解说 第一例句是表达现在进行时，第二例句是将来进行时，第三例句是现在完成进行时。（2）表达被动语态
句型 be +p.p.…（被动语态）
例：English is spoken in both Canada and the United States.（加拿大和美国都讲英语。）例：Those keys were found in your drawer.（那些钥匙是在你的抽屉里找到的。）例：It can be done much faster in this way.（这件工作用这个方法可以更加快速地做好。）
第四篇：Be动词和助动词的用法区别
1、be动词的用法。be am / is was 单数 are were 复数
现在时 过去时
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 + ？ 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? 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 / we did./ No, he / we didn’t.特殊疑问句： 疑问词 + did + 主语 + 动词原形 + 其他 + ? When did he / you get up every morning last year?
