口语：advertise(广告)，commercial(广告)有何区别？
用中文学英的人都知道，英语advertise(ment)的中文意思是“广告”，而英语commercial除了表示“商业的”也是中文“广告”的意思。
二者之间有什么区别？
我不想用中文来跟大家做“同义词辫析”，我把它们做英语口语训练，让大家把学过的英语用起来能“用”英语“说出”二者的不同：
1. Well,you know when an advertisement is shown in public places,like on the wall,or on road signs, in newsapers and magazines,it is called an advertisement.
这段高中英语不用读成中文都看懂了吗？
2.But when an advertisement appears on TV or on radio,it is called a commercial.So a commercial is a TV or radio advertisement.
以后见到advertisement或commercial，你“说出来”的不再是中文“广告”和“电视广告”，而是英语：
1. Well,you know when an advertisement is shown in public places,like on the wall,or on road signs, in newsapers and magazines,it is called an advertisement.
2.But when an advertisement appears on TV or on radio,it is called a commercial.So a commercial is a TV or radio advertisement，那么，你已经开始把英语学成英语了，你的英语口语也不会差到哪里了。
It's time for a commercial break
