be动词的用法内容

be动词的用法一、be动词的种类be动词包括“am”,“is”,“are”三种形式。（1）第一人称单数(I)配合am来用。句型解析析：Iam+…Iamtwelve.Iamslim.Iamtwelve.Iamslim.Iamastudent.Iamaboy.（2）第二人称(You)配合are使用。句型解析：Youare+…Youaremygoodfriend.Youaremygoodfriend.Youareagoodstudent.Youarepretty.（3）第三人称单数(HeorSheorIt)配合is使用。句型解析：She(He,It)is+……Sheisagoodgirl.Sheisshort.Sheisagoodgirl.Sheisshort.Sheisateacher.（4）人称复数(we/you/they)配合are使用。句型解析：We(You,They)are+……WeareinClass1,Grade7.Theyaremyfriends.WeareinClass1,Grade7.Theyaremyfriends.Youaregoodstudents.综合解析当使用be动词的时候，前面请先加上第几人称。be动词前面的人称，是不可随意替换的。例如：Iam,Youare,Sheis，并不会出现Iis,Youam,Sheare这样的情形。Be的用法口诀I用am；you,we，they都用are,is连着he，she，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。
