七年级一般现在时学案
一、Be 的用法：
口诀：I用 am， you用are， is用于他(he)、她(she) 、它(it)，单数is, 复数are. Eg: I am fine . She/He is at home. We/You/They/ My friends are students. ★否定句：在 be动词am/is/ are 后加not (some→ any) Eg: I’m not fine. You aren’t at school. He isn’t a student. ★一般疑问句：（用 yes 或 no 来回答的句子）
把be动词am/is/ are 提前，am→are; I/we→ you; my/our →your。 Eg: I am a teacher. → Are you a teacher?
You are in the classroom. → Are you in the classroom? He is ten years old. →Is he ten years old? ★特殊疑问句(以选择和转换句型为主):
常用疑问词：what（什么）, who（谁）, when(什么时间), where（在哪里）, why（为什么）, how（怎样）, how old, how many，how much等，
