[1] HEY boys, attention please! If you want to go to the US one day, you’d better be fully prepared, because, well, you and the boys in the US are a bit different. In my opinion, you’d better try to do the following things.

[2] Firstly, know how to knot a tie （打领带）. In the US, every boy above school age wears suits when they go to weddings （婚礼）. My friend Madison from Virginia said it shows respect to others. Do you know how to ____________? Learn how!

[3] Secondly, be a gentleman. I know in China some boys are still proud of being strong. But in the US, a good man should also be polite. Here are two examples: holding the door for people behind you and giving the seat on a bus to old people.

[4] The last is to learn something about football and baseball. Chinese boys like ping-pong, basketball and soccer, but American boys love football and baseball. They get very happy when they play and watch these sports. It’s not necessary to be a fan of football or fix （固定） your TV channel to baseball games. But in order to watch the sports with other boys, at least learning some rules would help.

[5] However, all this doesn’t mean that the American way is always the right way. We sometimes need to know the importance of another culture, but don’t feel you have to know that if it makes you uncomfortable. Have fun along the way!
