     Get ready, China. The world is coming! Every day 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 (人行道). 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 crowded 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 "Sorry" or "Excuse me".

     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. China is on her

way!
