Solve the Bike-to-Work PuzzleOne question has been puzzling bike riders today: Why don't more people ride to work?On paper, cycling is a clear winner over the alternatives. It's good for the environment, your bank account, and your body. Moreover, it's just fun. But one factor beats them all: inconvenience in the busy streets.The truth is that cycling to work isn't as convenient as it may seem. The ideal biking route is an uninterrupted commute — short enough for going to work or recovery but also long enough to be part of a workout(体育锻炼).If your commute is too long for biking,consider dividing the round-trip across two days: drive to work in the morning with your bike on Day One, cycle home, cycle back on the morning of Day Two, then drive it all home.Another good choice is to drive only part way and ride from there, or combine a bike ride with public transport.In any case, you'll probably find that the challenges of riding to work aren't as great as they seem. And while a bike lane(车道) might not be the path of biggest convenience, it's still worth traveling down.1) What does the phrase "on paper" imply (line 1,para 2)?A.pparently.B.Obviously.C.In practice.D.In theory.2) What is the main factor that causes people to give up bicycle-riding?E.It is not convenient to ride a bike in a busy street.F.It is not easy to repair a bike when it breaks down.G.It is too tiring to ride a bike to work every day.H.It is too slow to reach the office in time.3) The ideal bicycle commute should be____.I.easy and relaxing for ridingJ.very short for going to work.K.an uninterrupted oneL.cut into several parts4) What are you advised to do if your commute is too long for biking?M.Ride your bicycle once or twice every week.N.Cycle one day and take a bus the other day.O.Divide the round-trip across two days.P.Cycle two days and rest for one day.5) What is the author's attitude toward commuting by bicycle?Q.Negative.R.Positive.S.Objective.T.Indifferent.
