Cities are taking interest in electric scooter-share systems as an affordable transportation to cut down on pollution and traffic jams. The electric scooters, which weigh between 30 and 40 pounds, reach speeds of about 15 mph.

In September 2017，Santa Monica, California, became the first U.S. city to

have an electric scooter-share service. Users find and unlock one of the more than

1，000 scooters with a smartphone app. A ride costs $ 1，and then 0.15 cents for

each minute of riding throughout the beach town.

Bird, the startup operating the scooter-share, picks up the scooters every

night to them, and places them around Santa Monica each morning ready for people’s use. The company was created by Travis VanderZanden, who once worked in Uber and Lyft, after he realized ridesharing services failed to help with traffic jams and air pollution. Since its September 2017 beginning, Bird’s system has served more than 50,000 riders who have taken 250,000 trips — more than half of which have been in the last month. It’s since expanded (扩 张) to Venice, California, and some neighborhoods in Los Angeles and San Diego. Bird plans to expand to lots of markets by the end of 2018.

Competitors， backed by millionaires， are appearing. Two bike-share startups LimeBike and Spin, have spoken of plans to provide electric scooters in cities this year.

Electric scooters have also gotten the attention of Mayor Pete Buttigieg from South Bend，

Indiana. The city is interested in using them as a way to improve public transportation. South Bend was one of the first to use bike-share systems, which allow people to park ridesharing bikes on public land. “We love to be early pioneers，” said Buttigieg. “If we work out the safety problem, we would be open to welcoming the technology.”

“We need to make sure these new transportation systems are lawful and safe for users，”

Constance Farrell，a spokeswoman for the city of Santa Monica told CNN. “We would like to see electric scooters continue to operate in the city. They are in line with our goal of multi-modal living and carbon-light living. ” According to Farrell，there have been eight accidents, including one with a serious head injury， in Santa Monica after the scooters rolled out. Users are required to have a driver’s license (驾 照），shouldn’t ride on sidewalks or have other passengers on board.

Bird has given out free helmets to some riders and tells its users to ride in bike lanes, but some users ride on sidewalks, and most U.S. streets don’t have bike lanes.

“The global community of cities is going to have to work this all out for scooters，”Buttigieg said. “They can move unbelievably quickly. That’s exciting，and a little dangerous. ”

B. Because many cities had electric scooter-share services.

C. Because it is lawful and safe to use electric scooters.

D. Because cities need better ridesharing services.

2.The words “ are in line with” in Paragragh 6 probably mean “ ”.

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.

A. a special kind of robot invented by doctors

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.

A. more tools B. a robot machine

C. a video camera D. telecommunications

5.Which of the following is NOT true?

A. Robotic operation is good for doctor training.

B. Robotic operation has been used in the USA.

C. Experts speak highly of robotic operation.
