观察与思考：
不定冠词a与an的用法：冠词a与an是虚词,只用在单数(单数/复数)可数名词前,如a ruler(一把尺子)；an用在以元音音素开头的单数可数名词前(注意：不是元音字母开头的单词前),如an apple(一个苹果)。

答案： 单数；a ruler；元音；an apple

观察与思考：
“What colour + be + 物品？”是一个特殊疑问句,用来寻问物体的颜色,其答语既可以直接用表示颜色的词,也可以用“It's/They're + 颜色”。主语是单数时,be动词用is,回答一般用“It's + 颜色”表示；主语是复数时,be动词用are,回答一般用“They're + 颜色”表示。

答案： 颜色；is；It's；are；They're
