Step 1 Review and Fun time:
用实物投影展示P40学生照片，让学生猜Who is he/she?
第四张选用教师小时候的照片，当学生猜出后第一课时用老师的照片导入话题，本课时再用猜测意义不大。或者第一课时教师可以采用名人，或者学生自己的照片导入是否更好？

T; Yes. This was me twenty years ago, this is me now.
T；Twenty years ago, I was a little girl. I could draw and write. I couldn’t speak English. Now I am an English teacher. I can read and write English. I often go to the English Club at the weekends. 师指着照片，用书上40页的句型做示范汇报。
