教学片段：　　

老师：同学们上午好！今天我们来讲宾语补足语。英语中，有些及物动词后接宾语时，还需要加一个词或短语来补充说明宾语的情况，这样的词或短语叫做宾语补足语。那么请大家从课文中找出几处关于宾语补足语的例句。　

e.g. Now when people refer to England you find Wales included as well.　　

       So to their surprise, the three countries found themselves united.　　

同学们可以看出，例句中included是作find的宾语补足语，united是作found的宾语补足语。形容词作宾语补足语时，通常是放在make, get, find, keep, let等动词的后面。　　

接下来教师通过“辨识-拓展-理解”的步骤依次具体讲解宾语补足语的其他用法。

以下是一位老师在进行词汇教学时的情景：

Step1复习(revision)

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）

T：It is too hot. I’ll take off my sweater. Please take off your jacket．

（伴随动作，一次教授词组：take of, put on, hang up和put away）
