Yes,主语+amis/are./No,主 -Are you hungry?-Yes,I 简短回答 语+am/is/are+not. am./No,I'm not. ★易错点 否定句缩写：is not→isnt;are not→aren't;am not不能缩写为ammt。 在正式写作中，缩写（如he's,they1e)可用于口语，但书面考试中注意区分。 3.常见用法场景（初一上/中考高频） ①介绍姓名/身份 例：I am Tom./She is a doctor:. ②描述状态/特征 例：He is tired./The weather is fine. ③表示年龄（常用“主语+be+数字+years old) 例：My sister is ten years old.. ④表示位置 例：The cat is under the chair. ⑤表示时间、天气、日期（用It作主语） It is 7 o'clock.It is cold today.It is Monday. 4.主语与be动词的搭配口诀 I用am,you用are,is连着他她它。单数名词用is,复数名词全用areo 5.易混点辨析 (1)be动词与实义动词的否定/疑问区分 动词类型 否定/疑问方式 例句 直接在be后加not/提be be动词 She is not here./Is she here? 到主语前 She does not like milk./Does 实义动词 借助助动词do/does she like milk? ★考点：学生常把be动词当作实义动词处理，如错误写成She doesn't is a teacher:(正 确：She is not a teacher.) (2)be动词缩略形式与否定缩写 完整形式 缩写 示例 Iam Im I'm happy. you are you're You're smart. heis he's He's ten. she is she's She's a nurse. itis its It's time. we are we're We're friends. they are they're They're students. is not isn't He isn't tall. are not aren't They aren't here. 注意：amnot没有缩写形式；在口语中常用“aint”,但非标准用法，中考不考。 二、专项训练 (一)单项选择（共8题） 从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。 1.- your brother a middle school student?
