(设计意图：此环节为巩固单词.给一定时间让学生消化，并通过小组或全体默写的形式来督促学生，做到及时的查缺补漏。以便达到“趁热打铁”的效果。这一环节有少部分的学生往往不达标，需要利用自习课或课余的时间让小组长跟踪检查，尽量能让全部学生顺利过关。)
Step 4编故事学单词
An Interesting Job
Joe Brown has a very interesting job. He is a police artist. Some people see crimes and then talk to Joe. They tell him what the criminal looks like. Then Joe draws a picture of the criminal, and the police put it in newspapers and on television to find him.
He wants to draw a good picture of each criminal, but this job is sometimes difficult. Many people don’t always see things the same way so they may describe the same person differently. Also, they don’t always remember well. “The criminal is of medium build and young. He has long straight brown hair and big eyes,” says one woman. Another woman says, “He is tall and thin, and he has curly blond hair. He’s about thirty years old.” In the end, the real criminal is short and heavy old man, and he has short black hair!
乔.布朗有一份非常有趣的工作。他是一位警察艺术家。一些人看到犯罪活动并告诉他罪犯的长相。然后乔画出罪犯的图像，警察把图像刊登在报纸上并且在电视中播放来找到他。
他想把每一位罪犯的图像画的很逼真，但是这项工作有时是困难的。人们并非总是以同样的方式看待事物，所以他们会将同一个人描述的不一样。另外，他们总是记的不好。“罪犯中等身材并且年轻，他留着棕色的长直发，大眼睛，”
一位妇女说。另一位妇女说，“他又高又瘦，留着金色的卷发。他大约三十岁。”最后，真正的罪犯是个又矮又胖的老男人，留着黑短发
(设计意图：词不离句，句不离篇。在学生掌握本单元单词的基础上，再学习由本单元的生词编成了一篇小故事，引导学生不仅记忆词汇本身的意义，同时在具体的语境中体会它的意义。体现了词不离句的教学原则。有助于学生学习理解和使用本单元的词汇。)
Step 5 Mind map
1.Get the students to read the mind map and fill in the mind map according to the story , they can discuss in groups.
2. Get the students to retell the story using the mind map.
(设计意图：把故事和思维导图结合起来，让学生加深对本单元词汇和短语的理解，使学生对词汇从逻辑范畴上记忆词汇。进一步把词汇和具体语境的连接起来，巩固对词汇的记忆。)
