英语翻译
A person riding a bicycle uses little energy to make the bicycle move,and there is no pollution at all when you are riding.Even so,in developed countries,most people don’t travel to work by bicycle.It is not because the bicycles are expensive or people feel tired if they ride to work.It’s because the number of cars on the roads becomes more dangerous to ride a bicycle.【As a result,more people put their bicycle away and go to work in their cars and,in this way,the situation（情形）is made more serious.】Perhaps the best way to make riding safer and more popular is to create paths（开设通道）only for bicycle,and to make it so difficult and expensive for drivers to take their cars into the city that they will to back to using their bicycle.
