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 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 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 doctors work. If we want to use the robot in the operation, we must solve the problem of   _  . A) top doctors B) smaller movements C) doctor training D) high-speed telecommunications

When I was at university,I studied very hard.But a lot of my friends did very little work.Some did just enough to pass exams.Others didn't do quite enough.Fred Baines was one of them.He spent more time drinking in the Students' Union than working in the library. Once at the end of the term,we had to take an important test in chemistry.The test had a hundred questions. In my room the night before the test,Fred was watching TV.Fred usually worried a lot the night before a test.But on that night he looked perfectly calm.Then he told me of his plan."It's very simple.There are a hundred questions and I have to get fifty correct to pass the test.I'll take a coin into the examination room.I haven't studied a chemistry book for months,so I'll just toss the coin.That way,I'm sure I'll get half the questions right." The next day,Fred came happily into the exam room.As he sat tossing a coin for half an hour he marked down his answers.Then he left,half an hour before the rest of us. The next day,he saw the chemistry professor in the corridor."Oh,good,"he said,"Have you got the result of the test?"The professor looked at him and smiled,"Ah,it's you,Baines.Just a minute."Then he reached into his pocket and took out a coin.He threw it into the air,caught it in his hand and looked at it. "I'm terribly sorry,Baines,"he said,"You failed!" Fred Baines was one of those who   _  . A) did just enough to pass the exam B) didn't work hard enough for their studies C) had too much other work for the Students' Union D) were quite good at passing exams

Mr. Robinson never went to see a dentist, because he was afraid , but then his teeth began aching a lot, and he had to see a dentist. The dentist did a lot of work in his mouth for a long time. On the last day Mr. Robinson asked the dentist, "How much is all the work going to cost ?" "Twenty-five dollars," said the dentist. But he didn't ask him for the money. After a month Mr. Robinson phoned the dentist and said, "You haven't asked me for any money for your work." "Oh," the dentist answered, "I never ask a gentleman for money." "Then how do you live?" Mr. Robinson asked. "Most gentlemen pay me quickly, the dentist said, "but some don't. I wait for my money for two months, and then I say, 'That man is not a gentleman,' and then I ask him for my money. _   cost twenty-five dollars. A) The first day'work of the dentist B) The last day's work of the dentist C) Half the dentist's work D) All the dentist's work
