1、Be 動(dòng)詞專項(xiàng)練習(xí)be動(dòng)詞的一般現(xiàn)在時(shí)有三種形式，即：am, is, are（翻譯為 “是”）1.如果主語是第一人稱I （我）時(shí)，be動(dòng)詞用am。如：I am a student我是一名學(xué)生。I am還可縮寫成I'm。如：I'm David.我是大衛(wèi)。am 與 not 不能縮寫 。如： I am not a bad boy.2. 如果主語是 you （你，你們） , they （他們，它們，她們）或名詞復(fù)數(shù) （兩個(gè)以上的人或物）時(shí)， be 動(dòng)詞必須用 are。如：Are you twelve?爾是十二歲嗎？Tom and Lily are good friends. 姆和莉莉是

2、好朋友。They are at school 他們在學(xué)校。are與主語還可縮寫。如： We are= We're They are=They're, You are = You'ren are 與 not 可縮寫成 aren't。如: They aren't student他們不是學(xué)生。3. 如果主語是單數(shù)名詞、 不可數(shù)名詞或單數(shù)第三人稱代詞(he, she, it 日be動(dòng)詞用 is。如:My mother is a teacher的媽媽是一名老師。He is a student他是一名學(xué)生。is 也可與主語縮寫 ,如 : He is = He'

3、;s, My mother is = My mother's等。但是This is不可縮寫。而is與not可縮寫成 isn't。如:This isn't a boo延不是一本書。4. 句中含有 be 動(dòng)詞的陳述句變一般疑問句。把be動(dòng)詞提到句首，be動(dòng)詞要變大寫。注意第一人稱 變第二人稱。回答時(shí)用yes或no表示，結(jié)構(gòu)：Yes,主語+be 動(dòng)詞，No,主語+be動(dòng)詞+not如：It is a book.變?yōu)椋篒s it a book?5. 句中含有 be 動(dòng)詞的肯定陳述句變否定句。先找肯定陳述句中的be動(dòng)詞，在be動(dòng)詞后加not.如：It is a book.變?yōu)?It

4、 is not a book.根據(jù)以上敘述我們可以把動(dòng)詞的用法以口訣的形式表述出來：我(I)用 am,你(you用 are,is連著他(he她(she),它(it);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(hào)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(dòng)詞用法練習(xí)題：一.選擇正確的be動(dòng)詞填空1.
