Hi, Grandpa KFC, I'm Li Hua, a 18year-old-girl in high school.
I'd like to work in KFC in the coming winter holidays.
You don't need to worry about my ability, I ever worked in a restaurant last summer with my frunt English and hardworking style.
Looking forward to your feedback, thank you!

Dear Sir or Madam,

I have got that you will recruit a server during the winter holiday. I want to apply for that position.

My name is Li Hua, a 18-year-old senior high school student. The reason I want to apply is that I think i am competent to this job. For I obtained experience of this kind of job during the last summer holiday.

My English is fluent enough to communicate with others and I'm diligent and resposible for what i have done, what i'm doing and what i will do.

Looking forward to your prompt reply.

Best Regards
Li Hua

第一段开门见山地说你想邀他来中国玩。这里写个两三句就可以了。
第二段可以介绍一下介绍一下中国的特色以及你安排的行程。
第三段可以回顾一下你们原来同窗的情谊。
第二第三段当然是重点，我不知道你你一句话能拉到多长，总之写差不多整个篇幅的三分之二差不多。
最后再表达一下你希望他能来的强烈愿望。

ps：我都不知道现在高中生英语写作都要300个字了么，我才毕业一年呀……

My favorite teacher, she taught us the language, as well as of our class. She is about 30 years old, tall , very slim. Long black hair is often put on the shoulder, like a waterfall , a very beautiful. Bridge on the shelves with a pair of glasses, looks are gone and the special spirit. A pink little mouth always say so much that it constantly sweep the dust in our hearts.
　　Teachers are always so gracious. When we listen, she is smiling and we talk. Even if we do something wrong, nor scold us, to help us to correct errors only patience.
　　After class, teachers like our big sister. When do morning exercises, she did with us, although she has not done so, is to stick with day after day. At noon time, teach us to play badminton. Class, the teacher saw me not to shoot the basketball, take a one off. Just came up and kindly said: "Stevie WONG, I'm going to teach you. "With that, hands-on teaching me. I earnestly learn the two breaks for ten minutes, had learned to shoot a basketball.
　　Teachers also often says, the body is the capital of revolution, a healthy body, better learning and work. From then on, I know that life is movement, movement can give you pleasure and health. Little by little, I liked sports.
　　This is my favorite teacher, you like it, like, come on tell me.
