【答案】In recent years, haze weather has become an environmental issue worrying so many cities, which triggers widespread concern about air quality.
There are mainly two contributory factors behind haze. First, quantities of harmful fumes are discharged from factories, spreading in the sky and blocking the sunlight. Second, since the number of cars in the city has enormously increased, exhaust emission is gradually becoming another main factor contributing to haze.
Faced with such a serious situation, we must take effective measures accordingly. For instance, new laws and regulations must be passed to impose strict controls on industrial pollution. Besides, to set some limits on drivers going out too frequently or tax them if they travel a long time, say, more than five days a week.
