① How to ask the price of the clothes?
—How much is…? —It's…

②哪些词可以修饰主语呢？
this/that/these/those/the…
用法小结：this, that后跟单数名词。these, those 后跟复数名词。冠词the 后可以跟单数名词，也可以跟复数名词。
③用来修饰名词的表示颜色的形容词该放在哪里呢？
（3）根据主语的不同分两种类型的句式结构：
① How much + is + the/this/that（等限定词） + 表颜色的形容词 + 名词单数？
② How much + are + the/these/these（等限定词） + 表颜色的形容词 + 可数名词复数？

Let some Ss read the words in the boxes.

（2）Now can you make sentences in the chart with the words in the three boxes? You should pay attention to the single or plural form of the words. First, you can make ten sentences.
Ss ask questions using the words in the boxes then write down the words in the chart.
（3）Let some Ss read their questions. Then check the answers.
（4）Let Ss say the rules:
① the/this/that + 表颜色的形容词 +名词单数
② the/these/those +表颜色的形容词 +可数名词复数
（5）Now let's make another ten sentences on your workbook.
5.Practice 3b
