French doctors and American scientists have reported doing an operation in which the doctor was 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 between the doctor and the robot. Technology must be able to send a doctor's order to a robot to move the tools quickly.

Experts also say a successful robotic operation will improve an operation. For example, the robot can make much 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 possible 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 doctors work.

3.If we want to use the robot in the operation, we must solve the problem of __________.

A.high-speed telecommunications B.top doctors

C.doctor training D.smaller movements

4.If the smaller movement can't be done by doctors in the operation, we may use __________ to solve it.

A.telecommunications B.a video camera C.a robot machine D.more tools

5.Which of the following is NOT true?

A.Experts speak highly of robotic operation. B.The robot is used to watch the patient clearly.

C.Robotic operation is good for doctor training. D.Robotic operation has been used in the USA.

If you dropped a piece of fruit on your computer keyboard, would you think about eating it again? What if you dropped it in the toilet? Bacteria(细菌) can live everywhere, even in some unexpected places.

If you eat at your computer, sneeze on your keyboard, or sit down to surf the Internet without first washing your hands, your computer keyboard could be bad for your health. According to the US National Research Centre, the average computer carries 400 times more bacteria than a toilet bowl(抽水马桶) does.

Could one of the dirtiest things in your home be right in your hand? Yes. The TV remote control. It gets dropped on the floor, put on the sofa and everyone in the house holds it. Scientists found that about half of the tested remote controls carry the cold virus(病毒).

Don’t forget your toothbrush. Do you put it in the bathroom? Studies show that flushing(抽水冲洗) the toilet releases(释放) bacteria in the air. Bacteria can remain in the air for at least two hours. They may pollute your toothbrush. You can find ways to solve this problem. Try to keep your toothbrush far from the toilet. Make sure that it is in an upright position after each use. It’s also important to change your toothbrush every three months.

Here are some other places to watch out for:

At home

The kitchen is one of the places with the most bacteria — more than the bathroom. Dishcloths and kitchen sponges(海绵) are great places for bacteria since they are always wet after being used. Try to make them dry.

At school

When you put your schoolbags on the floor or in the bus, many bacteria can live on the bottom(底部) of it. Try to clean your schoolbag often.

In public places

Escalator handrails(电梯扶手), shopping cart handles(推车手柄), public books and magazines are top bacteria carriers. That’s why the first thing to do when getting home is to wash your hands.

Yes, bacteria are everywhere. But don’t be too afraid to touch those things. Most of bacteria are harmless. Just remember to wash your hands regularly. It is the most useful way to protect yourself from bacteria and viruses.

回答下面5个问题,每题答案不超过6个词。

1.Where can bacteria live? _____________________________________________.

2.How many of the tested remote controls carry the cold virus? _____________________________.

3.How often should you change your toothbrush? ________________________________________ .

4.Why are dishcloths and kitchen sponges good places for bacteria? _________________________ .

5.How can you protect yourself from bacteria and viruses? _________________________________ .
