3.展示环节：
（1）将Grammar的语法句填写并熟读。（2）展示3a部分的答案并简单讲解
（3展示3b中的答语并每人用一两个句子简短描述个人的变化。（4）完成图表并仿写对话
观察与思考：（1）Are you as friendly as your sister?.
“as+形容词/副词的____+as”表示“与……一样”，其否定形式为“not as/so…as”,表示前者不如后者，注意“so+形容词/副词的原级+as”只能用在_____句中。
( 2). She is a little more outgoing than me.
a little 表示“稍微，有点”的意思，用来修饰形容词、副词的原级和比较级，
