建议信（一） 假定你是李华, 你的朋友张柯发e-mail给你, 就买什么样的英语词典想听听你的建议。请根据下列提示, 用英语给他回一封120个词左右的e-mail, 推荐他买电子词典。 1. 方便、快捷; 2. 内置多部词典、能发音; 3. 能储存资料; 4. 其他…… 建议信（二） 假设你是李华, 请根据以下要点写一封信, 劝说全校同学过低碳生活(live a low-carbon life)。 1. 陈述理由: 为什么要过低碳生活? (环境质量日益恶化等) 2. 如何过低碳生活? 提出至少三条建议。(必要时才开灯; 让电器按节能方式运转; 骑自行车; 限制塑料袋使用; 垃圾分类等) There are several factors leading to my suggestion. To begin with, with the electronic dictionary being much smaller than the common one, it is convenient for you to carry it wherever going. Additionally, you can get what you want in the electronic dictionary as soon as possible, for consulting this kind of dictionary is really a piece of cake. When meeting with the useful material, you can store it as much as possible because there is much RAM(内存)in it. What makes it outstanding from a variety of others, I think, is that it can give you a vivid, clear and correct pronunciation just like a teacher standing by you. With so many advantages, why not buy one? I do hope my suggestion will be useful to you. Yours, Li Hua As living a low-carbon life is a good way to reduce emissions of greenhouse gases, I shall carry out my plan in the following ways. To begin with, I shall only turn on the lights when necessary and keep the refrigerator and air conditioners working in the low-carbon mode to save energy. Additionally, the bus or bicycle will be my first choice. Last but not least, not only will I limit the use of plastic bags when I am shopping, but also I will separate my rubbish into non-recyclable and recyclable waste whenever it is possible. I hope that more and more schoolmates will join in the activity. 本文来源：https://www.wddqw.com/doc/0518fba6e109581b6bd97f19227916888486b9fd.html
