     Get ready, China. The world is coming! Every say lots of foreigners come here as business people or

tourists. And even more people will come in 2008 for the Beijing Olympics. When they come to China, we

should do something to help them enjoy themselves and like China and the Chinese people.

     But there are some things they may not like:

     1. Traffic problems Cars park on sidewalks. Bus drivers drive so fast that they make people who are

trying to cross the street afraid.

     2. Queue jumping At the post office, or even at McDonald's, people push to the front of a line instead

of waiting.

     3. Bumping Too many people are crowed onto buses and trains. This makes people feel terrible, and it is

not safe, either.On a bus in North America, people try to make themselves smaller and they'll say "Excuse

me" or "Sorry" if they knock into someone. In China, people make themselves bigger with no "Excuse me"

or "Sorry"

4. Littering I notice this everywhere. Some people throw rubbish onto the ground even when there is a

rubbish bin (箱) right next to them. Most Chinese people are just as unhappy with these kinds of things as

I am. And, certainly, the government (政府) has known the problems and is trying to do something

about them.

How to improve our life? Many people think that they have to accept whatever life throws at them. They’ll say, "This is my destiny(命运).I cannot change it."

Of course not! You don’t have to suffer needlessly. Your life depends on you, not on any other external(外部的)factor.

I know a woman who says she just accepts what life gives her because she has done everything she can to improve it. Guess what her lifestyle is? She wakes up in the morning, goes to work, comes back home, relaxes, chats with people, watches TV, and then goes to sleep. Next day, the same routine cycle follows.

Huh! Is this what she calls "doing her best"? She believes she has tried her best and just accepts it in her heart that this is the life that has been intended for her and that her luck can only change if God wills it. She hasn’t realized that we have to do our share of making the effort to live the life of our dreams.

Remember that you harvest what you sow. You have to get off the sofa, get your eyes off the TV screen, get your hands off the phone(unless it contributes to your success),and get your mind and body to work! Don’t expect your luck to change, unless you do something about it. If something goes wrong, don’t just regard it as a temporary setback; instead, learn your lesson, make the most of the situation, and do something to solve the problem. It’s not enough to think positively; you also have to act positively.

If someone’s life is in trouble, do you just hope and pray that things will turn out fine? Of course not! You get to do anything you can to save the person. So it is with your own life. It is not enough to hope for the best, but you have to do your best. In other words, don’t just stand(or sit)there, do something to improve your life.
