【回答】
Recently, many cities of China were enveloped in a thick haze. Haze can cause great trouble to us. On one hand, it makes people unable to see things far away and thus affects traffic. On the other hand, haze can do harm to people’s health.
It is reported that haze is caused by many factors, of which air pollution is a major one. In order to avoid haze, we should take measures immediately. First, we should reduce air pollution. We can use public transportation instead of private cars and use clean energy. Second, we should plant more trees and grass to produce more fresh air. Only in this way can we bring back the blue sky.
