111 Unit8 Protecting the Environment 課堂練習(xí) Radio said yesterday that a very serious sand-dust storm,maybe the most serious one this year,attacked the whole North China.All the planes in and out stopped flying and all freeways were closed.It was said to grow from the central deserts of Mongolia for lack of rain in this area for almost ten months. News from the People’s Daily:Owing to people’s activities in the earth,the amount of carbon dioxide in the atomosphere is increasing and this leads to so-called greenhouse effect,that is,the temperature of the air is rising.Some icebergs in Antarctic and in the Arctic Ocean are melting and collapsing.An unexpected snow fell in Europe this August,and this has never happened before at this time of year.And worse still,the hole of Ozonophere over Antarctic is becoming larger day by day. From the above we can see that protecting the environment is not only a must for our life,but also a life and death problem for our existence.
