A driver stopped his car on a street side to have a rest．As he lay down in the seat and closed his eyes，a man came up and knocked at the window to ask the time．The driver opened his eyes,and looked at his watch．"It's 8：05，"he said．
Then he went to sleep again．But soon he was woken up(被叫醒) again because a woman was knocking at the window．"Sir，do you know the time?"She asked．The driver looked at his watch again，and told her it was half past eight．
In this way．the driver thought he could not have a good rest．So he wrote a note(纸条) and put it is on the window for all to see．It said．"I don't know the time．"
Again，he lag down in the seat for his sleep．A few minutes later a third person came and began to knock to the window．He said．"It's a quarter to nine"．
(1)

C．Three D．Four
[ ]
(2)
The first person knocked at the window of the car __________．
A．at five to eight
B．at half past eight
C．at five past eight
D．at a quarter to nine

(3)

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 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．
(1)
“Robotic operation”means“________”．
[ ]
A．
a special kind of robot invented by doctors
B．
an operation done far away
C．
an operation done with the help of a robot
D．
something done to mend a robot
(2)
We use the robot in the operation because ________．
[ ]
A．
it can send messages at a high speed
B．
even a top doctor can’t do the operation himself
C．
it can make the operation safer and better
D．
operations can be done without any doctors
(3)
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
(4)
If the smaller movement can’t be done by doctors in the operation, we may use ________ to solve it．
