    Starting next month, people in Washington will be able to rent a bicycle day and night with a membership card. A new company called SmartBike will make 120 bicycles available at 10 spots in the city. “There’s a lot of stress on our transit systems,” said Jim Sebastian, who manages bicycle and pedestrian programs for Washington’s Transportation Department. Offering another choice, Mr Sebastian said, “It will help us reduce traffic jam and pollution, as well as parking problems.” In the deal, the company will have the advertising rights in the city’s bus shelters and it has reached a similar deal with San Erancisco. Chicago and Portland, Ore. , are also considering the program.

For a $40 annual membership fee, SmartBike users can check out three-speed bicycles for three hours at a time. The program will not provide helmets (头盔) but does encourage their use. Similar programs have proved successful in Europe. The Vé1ib program in Paris and Bicing in Barcelona, Spain, both started around a year ago and already offer thousands of bicycles. Mr Sebastian, who started trying to bring bike-sharing to Washington even before its success in Paris and Barcelona, said he believed that the program could grow within a year and hoped that it would eventually offer 1 000 bicycles.

“But studies showed that many bikes would get stolen in a day, or within a few weeks,” said Paul DeMaio, a Washington-area bike-sharing consultant. Improved technology allows programs to better protect bicycles. In Washington, SmartBike users who keep bicycles longer than the three-hour maximum will receive demerits and could eventually lose renting privileges. Bicycles gone for more than 48 hours will be considered lost, with the last user charged a $200 replacement fee.

The low cost could be one of the program’s major selling points. At George Washington University in Foggy Bottom, one of the program’s 10 locations, students were unsure how often they would use SmartBike, but said its price made it worth a try.

70．The program can help the city in the following ways EXCEPT ________.

B. there are many other cities which show great interest in the program

C. the SmartBike company will be the first one to run bike-renting business

D. the SmartBike company will have 1 000 bicycles at the renting spots

72．What is the problem the SmartBike DC facing?

A. The bike technology should be improved.              B. Their bikes would get lost.

C. There are too few renting spots available.              D. There are too few bikes.

73．What will attract the customers most in the program?

A. Low price.        B. Great convenience.           C. New idea.          D. High quality.

What will city life be like in the future? Some people think that life in the cities is going to be horrible. They say that cities will become more and more crowded. As the number of people increases, there will be less space for each person. This overcrowding will cause other problems — more crime, dirtier streets , and worse problems with traffic than we have now. How will people find enough drinking water, energy (such as gas and electricity ), and housing? Because life will be hard, people who live in cities will worry more, and they may become sick. For these reasons, some say that nobody will want to live in city areas.
How can we deal with such problems as overcrowding, crime, and traffic? In some cities, thousands of people are already sleeping in the streets because there is little suitable housing — and because houses are too expensive. The crime rate isn’t going down. Instead, it is increasing so fast that many people are afraid to go out at night. Traffic is also getting worse. More and more often, traffic jams are so bad that cars don’t move at all for several streets. These problems have been getting worse, not better, so many people see no hope for the future of the city.
Los Angeles, California, for example, has no subway system and buses are slow. Instead, many commuters (乘、开车上班族) drive many miles from their homes to work. Many of these drivers spend several hours each day on busy freeways. New York, however, has a big transport system — buses, commuter trains, and subways. Because the public transportation is crowded and dirty, many people drive private cars, and the traffic jams are worse than that in Los Angeles. A taxi driver complains, “I was driving home, but in forty-five minutes I moved only two miles! Finally, I turned off the engine and just sat there. A lot of people left their cars where they were in the middle of the street and went into a bar for a few beers!”
On the other hand, some cities have clean, fast and pleasant public transportation systems. In Paris, France, and Toronto, Canada, for example, anyone can use buses or subways to move quickly from one part of the city to another.
