If you try to introduce yourself, you will probably talk about your name, where you are from. and your hobbies. But telling three things you know to be true, is unusual, too. So I will try to say three things I know to be true because they can tell more about me.
First, I have 2 older brothers. They are mean and not nice to me. They always say bad words to me, so I become angry and hit them. And I hate them. But they're my family, so I 'm sad. To make them change, I would try to understand them.
Next, Korea was divided into two coutries. There was Korean war on 1950s. After the war, two divided nations became South Korea and North Korea. However, I think we should be united again. So we can make a protest for government to try to unite the country again.
Finally, America's current president is Barak Obama. He is black but he became America's president proudly. It was really impressive that he stepped the stages and became first black president of America, where the racism is really serious.
As a conclusion, by telling three things I know to be true, will makes you to explain more about yourself or anythings.
