　　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!

French and American doctors have done an operation(手术) together in which the doctors were outside the operating room.This kind of operation is known as robotic operation ndline.

　　Doctor Marescaux did the operation in an office in New York City last month,while a sixty-eight-year-old woman patient was in a hospital in Strasbourg,France.

　　A doctor in Strasbourg got the patient ready.He placed medical tools and a small video camera in her stomach area(胃部).Doctor Marescaux in New York watched the patient on a video screen.Then he used the computer to send messages to the robot machine.

　　The robot moved the tools that cut the woman's gall bladder(胆囊) away.The woman got well soon after the operation and left the hospital two days later.

　　Experts say the main problem with such a robotic operation is based on high-speed telecommunications(通讯系统) between the doctor and the robot. Technology must be able to send a doctor's order to a robot to move the tool quickly.

　　Experts also say a successful robotic operation will improve an operation.For example,the robot can make such smaller movements(动作) than a person can.A robot machine can turn tools in ways that a doctor's hand cannot.

　　Doctors say such a robotic operation will make it possible safer and better operations in the future.They say it will improve doctor training.It will also mean that doctors could do an operation on people in dangerous places far away.And it could mean that people could have operations done by top doctors without having to travel to the city where the doctors work.
