问题     In the past twenty years, tiding bicycles has become more and more popular among people of all ages. 【R1】______But today an even greater number of adults cycle along roadsides and bicycle paths.

There are also a number of rules that riders should follow, especially when riding on streets or highways. Bicyclists should never ride against the traffic, nor should they carry other people on their bicycles. They are also supposed to ride in single line on busy streets and to walk bicycles across the busy intersections. 【R3】______
    In one recent year, the National Safety Council reported that 34 thousand bicycle riders were hurt in highway accidents. In that same year, another six hundred riders were killed. Since the introduction of crash helmets in 1980, the number of injuries and deaths from bicycling accidents had gone down. Today, more and more riders realize the dangers of bicycling. 【R4】______
