重点与难点：单句变复句。
指点迷津 授之以渔
回顾系动词be的一般疑问句和简略答语，会背单句变复句的规则及其用法
教学过程
1.预习：学习目标就是预习内容。
单句变复句的规则：①this ---these; that---those;
②she, he , it -----they
③单数名词变成复数名词（去掉冠词a , an ,）
一．预习检测：
①It 可代替一切没有生命的单数名词.如, --What’s your phone number, John --__123-9698.
②Excuse me,Sonia.打扰了,索尼娅.
Excuse me,意为“_____________”.常用于打扰别人.如, 借东西,问路, 插话,中途离开等场合. 准备打扰别人时,即“事先”要表示歉意时用Excuse me. 而Sorry和I’m sorry 指事后做错了事,心中难过,有愧于某人或某事,而表示道歉.如, --____. Are you Mark –No, I’m not. --____. A.Excuse me B. Sorry.
