第一篇：be動詞與助動詞的用法

be動詞與助動詞的用法

1.陳述句:be動詞第一人稱用am,第二人稱用are,第三人稱單數(shù)用is復(fù)數(shù)用are.助動詞do一般省略,直接用動詞,注意動詞時態(tài)和人稱變化.有時在動詞前加do,表示強調(diào),加強語氣.如:Do be quiet!

2.疑問句:be動詞直接提前,其他部分不變(由陳述句轉(zhuǎn)變).助動詞do同樣,由省略直接提前放置,后面動詞不變,注意do的時態(tài)和人稱變化.3.否定句:be動詞和助動詞do后面加not.be作助動詞用的形式如下： ①am, is, are, was, were ②助動詞+be：shall be, will be, can be, etc.③have/has/had + been（完成時）④am, is, …being（進行時）

（1）表達進行時態(tài)

句型 be + V-ing…（進行時態(tài)）例：What are you reading?（你正在閱讀什么？）I am reading a magazine.（我正在閱讀雜志。）

例：He will be taking a walk in the park at this time tomorrow morning.（明天早晨此時他將會正在公園散步。）

例：She has been teaching English in our school for years.（她已在我們學(xué)校教英語許多年了。）

解說 第一例句是表達現(xiàn)在進行時，第二例句是將來進行時，第三例句是現(xiàn)在完成進行時。（2）表達被動語態(tài)

句型 be +p.p.…（被動語態(tài)）

例：English is spoken in both Canada and the United States.（加拿大和美國都講英語。）例：Those keys were found in your drawer.（那些鑰匙是在你的抽屜里找到的。）例：It can be done much faster in this way.（這件工作用這個方法可以更加快速地做好。）

第二篇：Be動詞和助動詞的用法區(qū)別

1、be動詞的用法。be am / is was 單數(shù) are were 復(fù)數(shù)

現(xiàn)在時 過去時

英語中，be動詞選用單數(shù)還是復(fù)數(shù)，要由主語來定，主語是單數(shù)，就用單數(shù)，反之用復(fù)數(shù)。◆ 句中含有be動詞時： 肯定句： 主語＋be ＋ 其他 否定句： 主語＋ be ＋ not ＋ 其他 一般疑問句： Be ＋主語＋其他 ＋？

特殊疑問句： 疑問詞（what / who / when / where）＋ be ＋主語 ＋ 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動詞用法歌：

我用am，你用are，is 連接他她它。單數(shù)名詞用is，復(fù)數(shù)名詞全用are。變疑問，往前提，句末問號莫丟棄； 變否定，更容易，be后not莫忘記； 疑問否定任你變，句首大寫莫遲疑。

★ be動詞作謂語，它后面一般跟名詞、形容詞或介詞短語。

2、助動詞的用法。

英語句子按正常語序是“什么人或事物” + “做什么”，即，我們常說的“主語 + 謂語 + 其他”。① 主語為I 或復(fù)數(shù)名詞、代詞時：

肯定句： I / We / They / The students ＋ 動詞原形 ＋ 其他 ＋。We watch TV every night.變否定： 主語＋ don’t ＋ 動詞原形 ＋ 其他 ＋。

We don’t watch TV every night.一般疑問句 Do + 主語 + 動詞原形 + 其他 + ？ Do you watch TV every night? Yes, we do./ No, we don’t.特殊疑問句：疑問詞 + do + 主語 + 動詞原形 + 其他 + ？ How often do you watch TV? ② 主語為單數(shù)名詞或代詞時：

肯定句： 主語 + 動詞第三人稱單數(shù)形式 + 其他 +。He watches TV every night.否定句： 主語+ doesn’t+動詞原形+其他+。

He doesn’t watch TV every night.一般疑問句：Does + 主語 + 動詞原形 + 其他 + ？ Does he watch TV every night? Yes, he does./ No, he doesn’t.特殊疑問句：疑問詞 + does + 主語 + 動詞原形 + 其他 + ？ How often does he watch TV? ③ 過去時的句式（當句子時態(tài)為過去時時，動詞用過去式，不受主語單復(fù)數(shù)的影響）肯定句： 主語 + 過去式 + 其他 +。

He / We got up early every morning last year.否定句： 主語 + didn’t + 動詞原形 + 其他 +。

He / We didn’t get up early every morning last year.一般疑問句： Did + 主語 + 動詞原形 + 其他 + ？

Did he / you get up early every morning last year? Yes, he / we did./ No, he / we didn’t.特殊疑問句： 疑問詞 + did + 主語 + 動詞原形 + 其他 + ? When did he / you get up every morning last year?

蘇打水1.由連系am，is，are構(gòu)成的句子：變一般疑問句時把am，is，are提到句子的前面，句尾用問號即可。變否定句時直接在am，is，are后面加not即可。例如：

一、變否定句時相關(guān)詞的改變

肯定句變否定句時，除將謂語變?yōu)榉穸ㄊ酵猓渲衅渌~語也可能隨之改變，如將some改為any，too和also改為either，already改為yet，and改為or等：

There are some birds in the tree.樹上有些鳥。

→There aren’t any birds in the tree.樹上沒有鳥。

He likes the girl, too.他也喜歡這個女孩。

→He doesn’t like the girl, either.他也不喜歡這個女孩。

We have already seen the film.我們已看過這部電影。

→We have not seen the film yet.我們沒有看這部電影。

He likes singing and dancing.他喜歡唱歌和跳舞。

→He doesn’t like singing or dancing.他不喜歡唱歌也不喜歡跳舞。

二、不變謂語動詞而變其他詞語

有時將肯定句變?yōu)榉穸ň鋾r，不改變謂語而改變其他詞語：

Both of us went there.我們兩人都去了那兒。

→Neither of us went there.我們兩人都沒去那兒。

Both Jim and Mary can sing this song.吉姆和瑪麗都會唱這首歌。

→Neither Jim nor Mary can sing this song.吉姆和瑪麗都不會唱這首歌。

All of the books are worth reading.所有這些書都值得讀。

→None of the books are worth reading.所有這些書都不值得讀。

三、部分否定與完全否定

比較以下句子：

All of us laughed when we heard it.聽到這事時我們都笑了。(肯定句)

All of us didn’t laughed when we heard it.聽到這事時我們并未都笑。(部分否定)

Not all of us laughed when we heard it.聽到這事時我們并未都笑。(部分否定)

None of us laughed when we heard it.聽到這事時我們都沒笑。(完全否定)

【注】可能涉及部分否定的詞語有both, all, always, every等，即not both表示“并非兩者都”，not all 表示“并非所有的都”，not always 表示“并非總是”，not every表示“并非每個…都”。
