第三十三课 Lesson Thirty-three
一、教学内容
1.词汇（略）。
2.句型： 1） How long have you been at this school？ 2） I've been here for just over two years.
3.语法：继续学习现在完成时态的用法。
二、教具
录音机。
三、课堂教学设计
1.值日生报告。教师继续检查第30课课文复述。
2.通过如下演示，介绍本课要学内容：
T：（叫起一位同学） When did you come to this school？
S： I came to this school in 1997.
T： You came to this school in 1997. And then 1998， 1999. So you have been at this school for over two years.
为帮助学生理解，可在黑板上用以下线段表示：
板书 He/She has been at this school for over two years.
检查大家理解的程度：
T： How long has he/she been at this school？（引导全班回答）
Ss： He/She has been at this school for over two years.
教师再举一例：
T： Mr Hu（全班熟悉的一位任课教师）came to this school in 1985. How long has he been at this school？（启发全班回答：）
Ss： He has been at this school for over ten years.
在此基础上，教师可再换个说法：
T： You have been at this school for over two years， right？
Ss： Yes.
T： And we can also say： You have been at this school since 1997.（引导学生说出：）
Ss： MY Hu has been at this school for over ten years. And he has been at this school since 1985.
在此过程中，可利用黑板上的简表。
3. 准备听课文第1部分录音。教师布置听前提问（Pre-listening question）： How long has Kate been at this school？
听录音一遍，回答问题。打开书，学生跟录音机读两遍。
4.两人一组，练习课文第2部分。
5.教师组织学生就课文第3部分插图练习看图说话。
6.讲解本课新句型（见难点讲解）。
7.布置作业
1）抄写本课第1、2两部分，并练习朗读； 2）完成练习册习题。
四、难点讲解
How long have you been at this school？你在这所学校有多久了？
I've been here for about two years.我在这里大约有两年了。
这是现在完成时态的又一种用法。表示过去已经开始，持续到现在的动作或状态，可以和表示从过去某一时刻延续到现在的一段时间的状语连用。这些状语通常是由for和since组成的短语。例如：
for five weeks 5个星期了 for three months 3个月了 for thirty years 30年了 since nine o'clock this morning 自从今早九点 since last Friday 自从上周五since September 从九月份以来
