第26题: [多项选择]The importance of traffic regulations
2. The serious consequence of ignoring traffic regulations
3. What shall we do
Traffic Regulations
参考答案:
Traffic Regulations
Traffic regulations are indispensable to city life. In order that people are safe on the street, all vehicles must keep to the right side; cars must keep within the speed limits; people must keep to the sidewalk. In all large cities, pedestrians are not allowed to cross the street except at the crossing when the policeman or traffic lights signal them to do so.
However, these rules are too often ignored by people in some cities. Pedestrians cross the street anywhere or even stroll leisurely in the middle of the street without paying attention to the traffic on the move. Cars or trucks race along busy streets in total disregard of the safety of others. The streams of bicycles are especially dangerous when they dash about among the sea of moving vehicles and people. Sometimes they rush out unexpectedly from a side lane, giving people a start. Sometimes they knock people down, causing injury to them. And worst of all, sometimes they might get killed in their haste to cross the path of a bus. According to statistics, bicycles account for most of the road accidents in cities.
To cope with the situation, the police have started a campaign to make streets safer to the public. Television is very effective in warning people of the danger of disobeying traffic regulations. Penalties ranging from fines to imprisonment will be carried out against offenders. We hope things will become better with more and more people beginning to realize the importance of observing traffic rules.
