英语四级信件类作文【一】
信件如果有附件，可在信纸的左下角，注上encl：或enc：，例如：encl：2 photos（内附两张照片）。如果福建附件不止一项，应写成encl：或encs。
我们有时可看到在称呼与正文之间有re：或subject：（事由）字样。一般在信纸的中间，也可与“称呼”对齐。还应在底下加横线，以引起读信人的注意，使收信人便于在读信之前就可了解信中的主要内容。事由一般在公务信函中使用，也可以省略。
英语四级信件类作文【二】
You should write at least 150 words. Do not sign your own name at the end of the letter; use Li Ming instead. You do not need to write the address.
Dear Sir or Madam,
I m writing to lodge the complaint about the poor quality of an air conditioner that I purchased from Sun Appliance Company.
Frankly speaking, Sun Appliance has always been my favorite. On April 4, 2007, I bought the air conditioner (serial number 12345 from one of your chain store located in Lang Fang. The machine operated well at first, but ten days later, there was a fault that bothered me, that is, the fan made so much noise that I could not sleep well at night. Worse still, the cooling system didn t work well and the machine began to leak recently. Its poor quality ruined almost all my previous impression toward your products.
I strongly suggest that a repairman or a service engineer should be sent to my home without delay. I wonder if you could pinpoint the exact cause of the malfunction as soon as possible. If you can t, I am afraid that I will request for full amount of refund or a new air conditioner.
