be动词用法和练习题(最新整理)

1、be 动词专项练习be 动词的一般现在时有三种形式，即：am, is, are（翻译为“是”，“在”）1. 如果主语是第一人称 i（我）时，be 动词用 am。如：i am a student. 我是一名学生。i am 还可缩写成 im。如：im david. 我是大卫。am 与 not 不能缩写。如：i am not a bad boy.2. 如果主语是 you （你，你们）, they （他们，它们，她们）或名词复数 （两个以上的人或物）时，be 动词必须用 are。如：are you twelve? 你是十二岁吗？tom and lily are good friends. 汤姆和莉莉是

2、好朋友。they are at school. 他们在学校。are 与主语还可缩写。如： we are= were， they are =theyre, you are = youre。而 are 与 not 可缩写成 arent。如：they arent students. 他们不是学生。3. 如果主语是单数名词、不可数名词或单数第三人称代词（he, she, it）时，be 动词用 is。如:my mother is a teacher. 我的妈妈是一名老师。he is a student. 他是一名学生。is 也可与主语缩写,如: he is = hes, my mother is =

3、my mothers 等。但是 this is 不可缩写。而 is 与 not 可缩写成 isnt。如:this isnt a book. 这不是一本书。4. 句中含有 be 动词的陈述句变一般疑问句。把 be 动词提到句首，be 动词要变大写。注意第一人称变第二人称。回答时用 yes 或 no 表示，结构：yes, 主语+be 动词，no，主语+be 动词+not。如：it is a book. 变为：is it a book?5. 句中含有 be 动词的肯定陈述句变否定句。先找肯定陈述句中的 be 动词，在 be 动词后加 not.如：it is a book. 变为: it is not

4、 a book.根据以上叙述我们可以把动词的用法以口诀的形式表述出来：我(i)用 am，你(you)用 are，is 连着他(he)，她(she)，它(it)；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 动词用法练习题：一选择正确的 be 动词填空1. ia student.2. wefriends.3. hea good boy.4. shemy sister.5. theymy parents.6. you11 years old.7. ia doctor.8. my father
