李阳疯狂英语之国际肌肉三最短文 Chapter6:Be Polite

（单词翻译）

Good manners¹ are so important in today's society. A little effort of  being polite to everyone you meet can have great rewards². Of course there are other reasons for being polite as well. Everyone should be polite. Polite people show good manners. Moreover³, they are popular. On the other hand, rude people are looked down upon. Rudeness shows poor education. Therefore, why not be polite? A simple "Please", "Thank you" or " You are welcome" can make a big difference. If someone says dirty words all the time, it shows that something is wrong with his mouth. You'd better persuade him to watch his mouth.
