T: How many people are there in your family?

　　 Who are they? Is your mother tall/ short/beautiful ...?

　　【教学设计说明】本单元主要话题是描述人的外貌，因此从复习家庭成员的名称入手，并用已经学过的形容词对家庭成员进行简单的描述。进而自然的过渡到本单元的话题，这样以旧带新能帮助学生扩展思维。

　　(2) Present some pictures of different haircuts. Help Ss to understand the new words: long hair, short hair, curly hair, straight hair. Help them to describe persons by using "He/she has ...".

　　【教学设计说明】图片教学法是呈现新知识最简单有效的方法之一，学生通过图片，能更价值观的理解新单词的含义。
