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 (腹部). Doctor Marescaux in New York City watched the patient in 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 much smaller movement than a person can. A robot machine can turn tools in ways that a doctor’s hand cannot.
Doctor say such a robotic operation will make safer and better operations possible in the future. They say it will improve doctor training. It’ll 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 travel to the city where the doctors work.
Judge the following sentences true (T) or false (F).
( ) 1. “Robotic operation” means an operation done with the help of a robot.
( ) 2. We use the robot in the operation because it can make the operation safer and better.
( ) 3. If we want to use the robot in the operation, we must solve the problem of high-speed telecommunications.
( ) 4. If the smaller movement can’t be done by doctors in the operations, we may use a video camera to solve it.
( ) 5. The robot is used to watch the patient clearly.
(C)
There are some easy things you can do to protect the environment and the earth. Choose ideas from the list or come up with a few of your own.
● Plant flowers, grass or trees.
● Whenever you visit a park or beach, take away what you bring there—keep rubbish in a bag until you can put it in a dustbin.
● Turn off the lights, TV sets when you leave the room. This saves a lot of electricity (电).
● Turn off the tap (水龙头) when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.
● Keep the doors and windows closed in winter to keep warm air in.
