London has become a cycle friendly zone after the launch of a new bike hire scheme．It has been designed to encourage more people to cycle in and around central London． So how does it work？First you have to sign up to the scheme to be sent a key．The key will unlock one of the bikes，which are kept at docking stations in and around central London．You have to pay an access fee for the key and then you pay as you go，for the length of time you use the bike． Transport for London, which runs the scheme，are hoping to have 6，000 bikes and 400 docking stations in place by the end of the year．The new hire system is hoping to ease congestion in London and is expected to generate up to 40，000 extra cycle trips a day into the city centre. London Mayor Boris Johnston launched the scheme and said London had been “filled with thousands of gleaming machines that will transform the look and feel of our streets and become as common place on our roads as black cabs and red buses”. However，there have been a few problems since the scheme was launched last Friday．On the first day some people found they couldn’t dock their bike properly and their usage of the bike had not registered．Transport for London did admit they had been expecting a few “teething problems” and have said they wouldn’t charge for the first day as a“gesture of goodwill”．Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles． Despite the comments，the green-thinking London Mayor still seems very positive about things，saying，“My campaign for the capital to become the greatest big cycling city in the world has taken a gigantic pedal-powered push forwards．” 小题1:Which is the correct order of a bike hire？ a．pay a usage charge according to the time    b．pay for the key c．cycle in and around central London  d．sign up as a member to get a key A．b-d-c-a B．b-c-a-d C．d-c-b-a D．d-b-c-a 小题2:．Which of the following is NOT the “teething problems” of the scheme？ A．People were unable to lock properly． B．People could not dock the bikes properly． C．People had no enthusiasm about the scheme． D．It’s too expensive for some people to hire a bike． 小题3:．From the passage we know __________． A．the ‘cycling revolution’ failed once started B．the scheme will be put off due to the problems C．all the citizens in London are in favor of the scheme D．the London Mayor has great confidence in the scheme
