I was sitting alone in my car when I saw a man in his seventies, whose problem appeared bigger than mine. He stood near the edge of the road,2a kite spindle(风筝线锭) in his hands. Apparently, lost in thought, he stared skyward. I 3my neck to see how successful he had been in 4 the clouds. Following his string with my eyes, I almost lost5 of the other end. Finally, the kite rested on what seemed to be the highest branch of the 6tree in the park.  Obviously,  that was his grandson's kite!  The kite was a replica (复制品) of a beautiful bald eagle, and its wings spread 70pen. Grandpa had only one 8to his problem: cut the string.

"You wanted it to fly as high as it could. Bill. didn't you?" "Yes, Grandpa,9 wanted to keep it forever. " "There just comes a time when the only thing you can do is to cut the string and let it go. Perhaps by doing that, when it flies very high like real eagles do, it will come back to us. " Grandpa said.

Today I have to cut the final strings that kept my two boys 12my reach. Though I want to keep them forever, I have taught them to fly like an eagle.

    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. ”
