第一篇

　　Dear Editor,

　　Recently many places in China were blanketed with thick fog. The Air Quality Index in most parts reached 500.Everything around disappeared from our sight. Some highways were closed. More traffic jams and accidents happened .People had to wear masks .What’s worse, many people found it difficult to breathe.

　　The heavy hazy weather in China has been caused by many factors. First, the severely polluted environment contributed a lot to this nightmare. Second, the increase of cars in the city area plays an important role. The cars send off a lot of poisonous gases.

　　In my opinion, We should call on people to use more public transport, thus reducing the number of cars in the streets. Besides, some factories which cause pollution should be closed down. What’s more, We have to do more to raise people’s awareness of environmental protection . Only in this way can we expect to have more sunny days.

　　Best regards

　　亲爱的编辑,

　　最近中国很多地方被浓雾笼罩着。大部分地区的空气质量指数达到500。周围的一切就从我们的视线中消失了。一些高速公路被关闭。更多的交通堵塞和事故发生。人们必须戴口罩。更糟糕的是,很多人发现很难呼吸。

　　沉重的朦胧的天气在中国已经由许多因素引起的。首先,严重污染环境造成了很多这个噩梦。其次,汽车的增加在城市地区扮演重要的角色。汽车发送了大量的有毒气体。

　　在我看来,我们应该呼吁人们多使用公共交通工具,从而减少在街道上的汽车数量。此外,应该关闭一些工厂造成污染。更重要的是,我们必须做更多的工作来提高人们的环境保护意识。只有用这种方法我们才能期望有更多的晴天。

　　致以最亲切的问候

　　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 ever 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.

　　Hoping to hear from you soon and share your good ideas.

　　亲爱的大卫,

　　我很高兴收到你的来信。我从你的来信得知你关心的烟雾经常出现在中国的一些地区。谢谢你的关心。我也非常担心这种恶劣天气,因为它带来了很多不便或而伤害人们的健康,如交通阻塞,交通事故,糟糕的咳嗽,喉咙痛和肺癌等。

　　大家都知道,一个良好的环境来自良好的保护。所以我们应该尽我们所能发挥作用。尽量少开车,选择环保产品。只有当我们每个人都有环保意识才能更清洁的空气。

　　希望很快收到你的信,分享你的好想法。
