During the 15 days from New Year’s Eve to Lantern Festival, Beijing was affected by smog for more than half the time, because of which people suffered a lot. On the road people drove slowly because they could not see clearly. People also suffered from many illnesses caused by smog.

　　在15天，从除夕到元宵节，北京受烟雾超过一半的时间，因为这人受了很多苦。人们在马路上开车慢是因为他们看不清楚。人们也遭受许多疾病引起的烟雾。

　　The smog in Beijing has been caused by many factors, in which the increase of cars in the city area plays an important role. The cars send off a lot of poisonous gases, which in turn adds to the already serious air pollution.

　　北京的烟雾是由多种因素造成的，其中城市汽车的增长起着重要的作用。汽车发出大量的有毒气体，这反过来又增加了本已严重的空气污染。

　　In my opinion, the number of cars should be limited. We should call on the people to use more public transport. Only in this way can we expect to have more sunny days.

　　在我看来，汽车的数量应得到限制。我们应该呼吁人们多使用公共交通工具。只有这样我们才能期望有更多的阳光灿烂的日子。
