Rose: Hi, Dave. Do you think the weather is fine today?
Dave: Yeah. And the air is also clearer than ever before.
Rose: En, the newspaper reports that the air is less and less (pollute) these days.
Dave: That's true. Fewer and fewer people (drive) cars to work since the government started the traffic control two months ago.
Rose: But the control is going to end in two weeks. What'll happen then? Are cars coming back to the road?
Dave: That's true, too, we all hope it will never end. On the hand, the traffic control has made things tough for people driving cars.
Rose: But it's worth the trouble. I believe clean air is most important thing.
Dave: However, many people don't think so. they can't drive cars, they'll even have (difficult) getting to work.
Rose: They can choose to take a bus the subway. And they can even ride a bicycle. There're many other ways to choose from, actually.
Dave: Some people think buses are too crowded and riding a bicycle seems very (tire)．
Rose: Anyway, it's still (well) than being trapped in a traffic jam under grey clouds and in dirty air.
