Thirty years ago, most teenagers had bicycles, but now they are comparatively rare. 【C1】______. motor scooters (小型摩托车) are much more common. 【C2】______, this may seem to be a sign of progress but【C3】______the change is not necessarily for the better.
It is easy to see why young people prefer scooters. 【C4】______, they are much faster and do not require much physical effort; 【C5】______, you can take a passenger with you on the pillion (后 座) seat behind; 【C6】______, they give young people a feeling of independence, because they can travel further and impress their friends. 【C7】______, the disadvantages are equally obvious. 【C8】______first sight, scooters are more expensive to buy and to maintain, and【C9】______those under 16 are not allowed to have them. 【C10】______, greater freedom brings danger because speed encourages young people to take risks and as a result scooters are involved【C11】______more accidents, and the accidents are【C12】______more serious.
Bicycles are safer and easier to control. Years ago, teenagers had more experience with them because they【C13】______to ride as young children, and consequently knew what they were capable of. 【C14】______, many young people overestimate what a scooter can do and pretend it has the power of a motorcycle. 【C15】______, the fact is that bicycles are not very safe【C16】______in cities these days because there are more cars and drivers are not used to them and do not make allowances for them.
【C17】______, those who are old enough to ride scooters naturally prefer them. Those who are too young or cannot afford to buy a scooter probably find bicycles slow and uncomfortable【C18】______, and riding bicycles requires【C19】______experience of traffic than before. On balance, the change has been for the worse, 【C20】______for the 13-and 14-year-olds, but the only safe solution would be to have special lanes (车道) for cyclists.
