be 动词 (am/is/are) 的肯 / 否 / 疑问句式及三单用法高频易错点01
两者均为系动词表 “是”,根据主语人称 / 数精准搭配,核心语法差异及句式变形如下:
语法维度
am
is/are
基本结构
仅搭配主语 I(I am...)
is 搭配单数主语(he/she/it/ 单个人 / 物);are 搭配复数主语 /you(they/these/you...)
否定形式
I am not...(缩写 I'm not)
主语 + isn't/aren't...(is not=isn't;are not=aren't)
疑问形式
Am I...?
Is/Are + 主语...?
答句规则
Am I...? → Yes, you are./No, you aren't.
Is/Are...? → Yes, 主语 + is/are./No, 主语 + isn't/aren't.(答句用代词)
易错点提示
1. 主谓搭配错误(×):He am from China. → 正确(√):He is from China.(he 是单数,搭配 is)
2. 否定缩写错误(×):It is not a map. → 正确(√):It isn't a map.(四年级要求掌握基础缩写)
3. 疑问语序错误(×):You are from Canada? → 正确(√):Are you from Canada?(疑问句句
首必须提前 be 动词)
4. 答句代词误用(×):—Is she Jenny? —Yes, Jenny is. → 正确(√):—Yes, she is.(答句用人
称代词替代人名)

主语?,答句直接回应内容,无需 Yes/No,核心差异如下:
语法维度
who(谁,问人物)
where(哪里,问地点)
what(什么,问事物 / 姓名)
基本结构
Who + is + 主语?
Where + is/are + 主语?
What + is + 主语?
单元例句
Who is he?
Where are you from?
What's your name?
答句规则
直接用 “代词 + be + 人名”

直接用 “My name is.../It's...”
同义转换

疑问词 + be 动词 + 主语”)
2. 助动词冗余(×):Do who is she? → 正确(√):Who is she?(特殊疑问句无需加助动词
do/does)
