Dear David，
I'm glad to receive your letter. I have learned from your letter that you are concerned about the smog which frequently appears in some areas of China. Thank you for your concern. I'm also very worried about such terrible weather because it has brought much inconvenience or rather harm to people's health such as traffic jam, road accidents, bad coughs, throat hurts and even lung cancers and so on.
As everybody knows, a good environment comes from good protection. So we should do what we can to make a difference. Try to drive less and choose air-friendly products. Only when everyone has the environmental awareness can we have cleaner air.
I hope to hear from you soon and share your good ideas.

Dear Chris,
I am happy to hear that you’ve joined in an activity for protecting fresh water.
Yours sincerely,
Li HuaDear Chris,
I am happy to hear that you’ve joined in an activity for protecting fresh water. Water is necessary to our life and the development of national economy. It is often described as the source of all living things and the lifeblood of agriculture and industry. Without it, nothing could grow out and the world would become a terrible desert. The world we live in is now faced with a severe shortage of fresh water.
According to some official figures, more than 1,700 million people in the world don’t have enough clear water to drink now. Therefore, it is necessary for us to protect the water. I think, it is a shame that students leave the water running without turning off the tap after washing. We should actively save water. It’s our responsibility for the benefit of the future generations.
Yours sincerely,

Li Hua近期，雾霾Dust-haze天气频频发生，PM2.5(可入肺颗粒物)与PM10(可吸入颗粒物)这两个此前不被人熟知的词最近一直被许多人提及，环境保护越来越受到人们的关注。作为一名青少年，我们如何尽自己的微薄之力来保护环境，请以学生会的名义发出一个倡议。
　　要点：1.环保受到人们更多的关注;2.环境的现状;3.应采取的措施。
　　注意：词数120～150(格式已给出，不计入总词数)。
　　词汇提示：过低碳生活live a low-carbon life【写作 实践3】 ①My fellow students, recently, the Dust-haze weather hit the north of China over and over again, which had a great effect on people’s life and health. ②As a result, people are becoming more and more concerned about our environment. ③As we all know, it’s the development of industry and heavy traffic jams that have caused air pollution. ④So as a teenager, I think we should take some measures to protect our environment.
　　⑤On one hand, we’d better launch a campaign to raise people’s awareness of environmental protection. ⑥Also we can hold a speech contest about protecting environment to stress the importance of living a low-carbon life. ⑦On the other hand, do what we can to influence people around us to go to work or school on foot or by bike. ⑧As far as I’m concerned, every small step we take really counts. ⑨So please remember: together, individuals can make a difference.I learn!
