Today, I'd like to tell you something about the history of the United States. The United States covers a large part of North America. After winning freedom from England, it had only 13 states. Each of the states had a star on the national flag. As the nation grew, new states were formed and there were new stars on the flag. For a long time, there were 48 states. In 1959 and 1960, two more stars, standing for the new states of Alaska and Hawaii（阿拉斯加州和夏威夷州）,were added to the flag. Indians were the first people of the land. Many people came from England. It is for that reason that the language of the US is English.

    We have only one earth. It is the only environment for humans, animals and plants to live or grow in. However, we are polluting our earth every day. Good news is that the whole world has realized the serious problems and has taken action to fight against it.

    One would think that campers would know not to break the branches off trees for firewood, drive fast around the campground, litter, or leave a fire not looked after, but I've seen people do all of these things. No matter where you put up your tent, here are five things not to do at a campground.

    What's it like to be near someone who decides to arrive late at night? Last summer, on a rainy night at a state park in Vermont, we heard noises from excited kids and barking dogs very close to our tent after midnight. There is no beautiful way to set up camp in the middle of the night, so please, just don't do it.

    No one thinks that his dog is annoying, but we all know that some pets are better off left home. The only thing worse than a camper who stands by lazily as his dog barks at passers-by for no reason at all, is that he leaves his dog at his campsite while he goes off for the night.

    This is the most important and often unnoticed camping manner in the book. Nearly every campground has rules that do not allow noise late at night and early in the morning, but most places also don't have the staff to carry them out.

    You might accept leaving your bar of soap thinking that someone might have forgotten to bring theirs, but I can assure you that non one wants to use your leftover soap especially if it's hairy, so please take it with you.

    No matter how good your taste in music is, I'd say most people prefer quiet hours with the nature. The truth is that no one want to hear your music except for yourself. Headphones are a great invention, but since too many campers fail to pack them, don't forget your earlugs.

    Dear Mike,

    I am so grateful you are coming to see my father at 10:00 a.m. on Sunday. Here is how you can find North Street Hospital.

    After coming to the People's Square, you walk northwards at the traffic lights and then come to the gate of East Street Park. Turn right and walk along the road. You'll find the Police Station. And then turn left and go along the road and take the second crossing on the right. Go on until you reach the end. You'll find North Street Hospital in front of you.

    I'll meet you at the gate of the hospital. I'm sure you'll have no trouble coming here.

Yours,

Wang Ping
