Some people have to use public transport, some dislike it and still some love it. If everyone has a car and drives anywhere they want to go, there will be serious traffic problems on the road. Luckily, trains are a good form of public transport.

British people use trains a lot. This is especially so for people who are travelling from London to Paris. Every day about 20 trains leave London. They travel at a very high speed and people feel glad that the trains take only 2 hours and 30 minutes to reach Paris. It's much faster to travel by train than by bus or by car. This is because people have to drive cars or buses very carefully and slowly for many reasons, such as speed limits and traffic jams. However, when you are travelling by train, the speed is almost the same and there is no traffic jam for a train.

Besides, Londoners think taking a train is one of the safest ways of travelling on the ground. Trains take quite a number of quality tests while they are made. More importantly, they have to take many safety checks before they are used on the rail track.

What's more, trains in Britain are comfortable and provide fine services(服务) for their users. When you are on a London train, you will find that the train has comfortable tables and seats where people can sit. They also provide food services and power plugs(电源插头) for personal computers or mobile phone.

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.

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. 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 gallbladder (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 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 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.

A. it can send messages in a high speed.

B.even a top doctor can’t do the operation himself.
