学生 姓名 课题 教师 姓名 授课 日期 授课 :00- :00 时段 be动词及 there be句型 重点1、be动词am, is, are的用法。 难 点 2、there be句型的用法及各种句式变换。 3、灵活运用知识,举一反三。 教 学 步 骤 及 教 学 内 容 什么是be动词 一、am,is和are 的用法: 这三个词都是“是”的含义,但用法比中文中的“是”要复杂,英语中的am,is 和are都是be 的变化形式,根据不同的主语选用不同的动词,主语I 用am,表示复数的主语和单数“you”则要用are,其它则用is。 1.例句: I am a teacher.我是一名教师。 You are a worker.你是一个工人。 You are students.你们是学生。 She is Miss Gao.她是高小姐。 This book is mine.这本书是我的。 2.练习: She my good friend. I a student. You beautiful. You good friends. They tall. 二、陈述句变疑问句: 只需把主语和 be 动词调换位置 1、 例句:Am I a teacher? Are you a student? Is she beautiful? Are they good friends? There be句型的用法: 一、 构成: There be ...句型表示的是 “某处有(存在)某人或某物”,其结构为There be(is,are )+名词+地点状语。例如: There are fifty-two students in our class. There is a pencil in my pencil-case. 二、各种句式: 否定句:There be句型否定句式的构成和含有be动词的其它句型一样,在be后加上“not”。也可用“no”来表示。即:no + n.(名词)= not a\\an\\any + n.(名词)。 注意:no + n.(可数名词单数)= not a\\an + n.(可数名词单数);no + n.(可数名词复数)= not any + n.(可数名词复数);no + n.(不可数名词)= not any + n.(不可数名词)。 例如: There is an orange in her bag. →There isn’t an orange in her bag. →There is no orange in her bag. There are some oranges in her bag. →There aren’t any oranges in her bag. →There are no oranges in her bag. There is some juice in the bottle. →There isn’t any juice in the bottle. →There is no juice in the bottle. 一般疑问句:There be结构的一般疑问句变化只需把be动词移到句首,再在句尾加上问号即可。 1、例如: There is some money in her handbag.

→ Is there any money in her handbag? (疑问句和否定句中,some改为any, something改为anything.)

There is something new in today’s newspaper. →There isn’t anything new in today’s newspaper. →Is there anything new in today’s newspaper? 2、练习

There a book. There some apples.

There many oranges on the desk.

单词顺口溜:
