4、While the rest of the world carried on cycling during the 1950 s and 1960 s, America forgot how; even high—school children would drive to school．Recently there has been something of a renaissance（復興）in cycling, and in many areas it is a very useful way of getting around, especially where bike paths or bike routes have been built．You may well want to buy, hire or borrow a bike．

There are two important consequences of this earlier drop in cycling in the USA．One is that many people do not know how to cycle．That is, cyclists often behave more like pedestrians（行人）than motorists :they ride on the sidewalk or on the wrong side of the road; they do not care for stop signs or traffic lights; they ride without lights at night; they give no hand signals．The other consequence is that cycling is regarded by many people not so much as a way of getting from one place to another but as a way of life, a form of exercise, etc．As a result, large number of young Americans have ten-speed racing bikes．These are very high and fast and great if you are cycling long distances, riding up mountains or racing．At first, though, you may find them awkward（使用不便） for cycling in town, Sight-seeing or shopping—they are expensive, uncomfortable and hard to control until you get used to them, and unsuitable for rough stony roads．

There are also ordinary bikes around．If you get hold of one of these, you may find that the brakes work by pedaling（踩踏板）backwards．This is perhaps safer than ordinary brakes when it is wet, but it seems to be less effective．This arrangement also means you can’t pedal backwards in order to get the pedals in the right place for getting on or moving off．
