L:Oh,today's weather is awful.The wind blows so strongly and dust blows everywhere.
M:Yeah,it's terrible.But you know,it's not uncommon to have such dust storms in Beijing.
L:Why do the dust storms come so strongly this year?I've never seen such strong storms before.
M:According to the meteorologists view,the dust weather has much to do with the scarcity of rain,the dry air and exposed soil with immature plants in the area.
L:Right,right.
M:And the worsening desertification is another major reason.
L:To tell the truth,I don't like Beijing for two reasons.One is the pollution,and the other is the serious traffic jam.
M:Desertification and pollution caused by the heavy industries and car exhaust emission makes Beijing an entremely dirty city to live in.
L:In China,economic development has often been achieved at the cost of the environment.
M:But Beijing has tightened its environmental protection measures in the past few year.
L:Yes,Beijing hopes to host a "Green Olympics".
M:I hope Beijng starts to take on a new look now.
L:I hope so.
