[谋篇布局]
应用文的实际用途决定了其语言要简洁明了。主要有三个原则，即proper（恰当）、 precise（精确）和polite（礼貌）。具体要求体现为：需开门见山，文章一开始就要表明意图；行文逻辑清晰、目标明确；语气要恰如其分，注意语言的正式和礼貌，遵循交际原则。
高考书面表达多以日常生活场景为基础。在扩充细节的时候，同学们要结合平时的生活积累，在符合常识的基础上，充分发挥想象力。
投诉信作为英语文体的一种，目的是解决问题，比如消费利益受损、正常生活和工作受到干扰等。内容可包括：说明投诉的原因并表达遗憾；实事求是地阐述问题发生的经过；指出问题引起的后果；提出批评及处理意见，要求对方采取措施。此外，语气注意要冷静、郑重、克制，不必过于礼貌。但也要就事论事，不能人身攻击。

Because of the problems， I require to full require or change a new one. If you can change a new one， it will be the most wonderful way to solve these problems.

这是一篇中低档习作，得分18。其优点是：
1. 作者运用了衔接词，观点清晰，层次分明。
2. 活学活用了一些短语，如because of， after a while， look forward to， look through。
不足之处是：
1. 存在简单单词拼写错误。如：lose过去式应为lost；information是不可数名词，复数的形式不加s。
2. 时态、语态混乱。在第2段描述产品问题时，应统一用过去时态。如第2段第2句应改为I couldn’t connect the server when I was looking through the news. it was often losed connection to应改为it often lost connection to。
3. 中式英语过多，还有一些表达错误：第2段中的... during I use it应改为when I used it；it come to be fine应改为it turned out to be fine；第三段的I require to full refund应改为I require a full refund.
习作二
Dear Sir or Madam，
I am writing to you to complain about the poor quality of the router I bought from your store last week.
Having used it for several days， I found the router seemed to have been out of order and problems have arisen one after another. While I was searching for some information on the internet， it lost connection to server frequently， which annoyed me greatly. What made matters worse was that the signal of wireless network was not stable， which made it difficult for my iphone or ipad to connect to the net via WIFI， putting me to great inconvenience.
Therefore， I would be grateful if you could replace it with a new one as soon as possible. If not properly settled， a full refund would be acceptable as well. Thank you for taking it into consideration， and I’m looking forward to your early reply.
Yours sincerely，
Li Hua
