What colour is this flower? 单数答句结构：It’s + 颜色. 例：—What colour is this flower? —It’s purple. 2 复数主语问句（they /these/those + 复数物品） 结构：What colour + are + 复数主语？ 例：What colour are they? What colour are these flowers? 复数答句结构：They’re + 颜色. 例：—What colour are these flowers? —They’re purple. 3 颜色词语法特点 颜色形容词在句中作表语，**没有单复数变化**，无论问句是单数还是复数，颜色单词形式保持不变。 例：It’s green. / They’re green. 易错点提示 be 动词 is 只搭配单数主语；be 动词 are 只搭配复数主语；颜色形容词不受主语单复数影响，不需要加‑s 后缀。 小练笔 01 一、单项选择 (   ) 1.
