以下是一位老师在进行词汇教学时的情景:

互致问候后,教师将装有彩色小图片的信封分发给各小组。
T:Open the envelopes, please. You have something nice in them. What are they?
S:A green ear, a red ball, a blue plane, a yellow cat…
T:What do you like?
S:I like…
Step 2导入(1eading in)
PPT播放歌曲,师生共同演唱。
T:Let’s sing the song “Who Is Wearing Yellow Today”.
音乐结束后,教师并没有停下来,而是改编歌词继续唱。
T:Who is wearing blue today? Blue today? Blue today? Who is wearing blue today?
Blue today?
Step 3呈现 (presentation)
T:Who is wearing blue today?
S:You are wearing blue today.
T:Yes, I’m wearing blue today. I’m wearing a blue sweater now.
学生跟读:sweater, sweater, blue sweater
T:I like the blue sweater. If you like it, please say it out loud.
PPT展示粉红色毛衣图片
T:Do you like the pink sweater?
S:Yes, I like the pink sweater.
(借助学生穿着的服装,引出jacket等新词,展开活动)
