词语形式
advertisment（动词） suit（同义词） choose（过去式和过去分词）
hide（过去式和过去分词） tie（现在分词） shine（形愹词）
hairbrush（复数） appointment（同义词） at least（反义词）
balanced（名词） promise（名词） dirt（形愹词） polite(反义词） gentle（副词） encourage（名词） organize（名词）

advertising advertisment commercial 都做名词时的区别?要口语化一些的正规解释.
就好比一般英语国家的人都怎么用这三个词,最好有个例句解释下.
