       Some western countries insist that China is one of the world's biggest greenhouse gas emitters

(温室气体排放者). But in fact our government has taken actions a    1      to struggle with climate change.

       Firstly, the public are educated to p    2     more attention to the environment. As the government expects,

the people have reached a very h    3     level of knowing low-carbon economy (低碳经济). I    4      you

watch TV, listen to the radio or read newspapers, you'll find low-carbon lifestyle has become a fashion.

Secondly, developing renewable energy is another action. The government is b    5     many wind farms and

solar power stations in the deserts. Of course, w    6      a long time, China will continue using the coal. At the

same time, the government has been making l    7     to punish those people who dare to destroy the

environment. Besides, some s    8     have suggested that greening the deserts is more important than developing

new forms of energy. Their l    9     research shows that 80% of the CO2 in the atmosphere comes from

landuse.

      As we know, China hasn't a    10     a balance between the green lifestyle and the economic growth, but we

are on the way. We'll take more actions to reduce the greenhouse gas emission.
