Dear Mr. Smith,
I'm Li Hua, a student from Hongxing Middle School. I'm writing to apply for the position of volunteer you advertised on China Daily. My experience has made me a qualified volunteer for your activity.
First, I'm not only fluent in English but also have a good sense of cross-cultural communication, which enables me to provide good service. Second, I am familiar with the history of the ancient Silk Road and know many stories about it. Third, as an outgoing member of the Students' Union, I have gained much experience in organizing social activities. In a word, I think I wouldn't let you down if I were given this opportunity.

范文二：Family, Friends and People Around
Dear Peter,
I'm Li Hua. Learning that you want to learn Mandarin and are in search of a teacher, I'd like to recommend my friend Li Ming to you. Li Ming is a 20-year-old young man who studies in Zhejiang University, majoring in Chinese. Not only can he speak Standard Mandarin, but he is also able to speak fluent English. Having been the winner of both English and Chinese speech contests several times, he was awarded the Image Ambassador of his university. So with a good command of English, he surely has no difficulty in communicating with you. And when knowing that you want someone to help you with Mandarin, he is quite willing to offer help. I would appreciate it if you could take my recommendation into consideration.
Yours truly,
Li Hua
范文三：Personal Environments
Dear Sir or Madam,
I'm Li Hua, an exchange student from China. Having learned that you're looking for volunteers to monitor the water quality of the river, I'd like to be one of them. In my hometown, my family have lived on a river for decades. I know how important the river is to people. The river to us is what milk is to a baby. That is why I'm willing to join you in helping protect the river from being polluted through monitoring its water quality. I promise I will spare no effort to do the job and do it well. I would appreciate it if you could offer me the opportunity to do something for us all. Looking forward to your early reply.
Yours sincerely,
Li Hua
范文四：Daily Routines
Dear Peter,
I'm glad that you will come to study in our school as an exchange student. You want to learn about our daily life in school. I'd like to take Monday for example.
In the morning, we have classes from 8:00 to 12:00. After that, we have lunch in the school cafeteria. The food there is quite delicious and diverse. In the afternoon, we have more classes or some extracurricular activities. Sometimes we go to the library to read books or do homework. After dinner, we usually have some free time to do what we like, such as playing basketball, chatting with friends, or watching TV. At night, we go to bed around 10:00.
I hope this will give you a general idea of our daily routines. If you have any other questions, feel free to ask me.
Yours,
Li Hua
范文五：Information Security
The human beings are stepping into the information society. The information industry develops very rapidly, so do the hackers, trick-playing teens, exploring children, fraudsters, and serious white-collar criminals. Thus, information security becomes an impending important issue.
In case of information breach, the victims—government departments, organizations, institutions, or companies—will inevitably suffer great or small losses. Government may be threatened with national security. Companies may lose opportunities to develop new projects. And the public's and users' confidence will be damaged.
Technology is only a partial solution to information security. What's more important is that organizations and companies should promote the awareness of information security among their staff. However, since no system can ever be 100 percent secure, a prevention-only approach to information security management is not enough. Companies and organizations should adopt a dual approach to information security management by combining prevention and detection techniques.
范文六：An Application Letter
Dear Sir or Madam,
I am Li Ming, a would-be graduate from Nanjing University. My major is English. Through the job advertisement, I have learned that you are hunting for a qualified individual for a personal secretary to the General Manager of your esteemed company. I am fully convinced that I am the right person for the job.
I realize that my future boss is extremely busy. However, it is exactly the challenge of my prospective position that attracts me. I am sure that my honesty, carefulness, patience, expertise, commitment, and extensive knowledge will produce an excellent job performance. Next month, I am going to graduate from the English Department of Nanjing University, and I have over two years of secretarial experience. I have enclosed the details of my academic record, skills, and language abilities.
Thank you for your time in considering my application.
Yours Sincerely,
Li Ming
范文七：No Pains, No Gains
It is a well-known saying that "no pains, no gains". This simple yet profound statement encapsulates the essence of success and the efforts required to achieve it.
In life, we often encounter challenges and obstacles that test our resolve and determination. Whether it is in academics, career, or personal growth, the path to success is rarely smooth. It requires hard work, perseverance, and a willingness to put in the necessary effort.
Those who succeed are not born with innate talents or advantages. Instead, they are individuals who have embraced the idea that success comes through hard work and dedication. They understand that every step forward, no matter how small, is a step closer to their goals.
范文八：Electronic Dictionaries
The discussion about electronic dictionaries has never stopped in the past few years. Let's have a look at its advantages and disadvantages before drawing the final conclusion.
The biggest advantage of an electronic dictionary is its convenience. Whenever you meet new words or expressions, you can know the meaning quickly. What's more, with the development of science and technology, electronic dictionaries are becoming more and more advanced: they can pronounce the words clearly, provide sample sentences to illustrate word usage, and store difficult words for special memorization. Last but not least, electronic dictionaries are becoming cheaper and cheaper, and more and more students can afford them.
However, the negative effects are also obvious. To begin with, some students rely too much on the electronic dictionary and never put their heart into learning new words and expressions. In addition, some explanations are neither complete nor accurate, which are quite misleading.
Up until now, we can see clearly that an electronic dictionary is not beneficial or harmful in itself. The key lies in the user. So long as we can make proper use of it, it can be most helpful to us in many respects.
范文九：Smartphones and Communication
The popularity of smartphones has exerted great influence on the way people communicate, so much so that an increasing number of individuals contend that face-to-face communication is being replaced by texts and images on the mobile phone.
On one hand, it is pleasantly acknowledged that smartphones shorten the distance between families and friends. Even people from different sides of the globe can share pictures, feelings, and thoughts through various types of apps on the phone, thus building a long-distance connection.
On the other hand, as the picture warns us, too much smartphone addiction interferes with people's real-life communication. Statistics show that over 70 percent of face-to-face communication consists of facial expressions and body language, which is why people should stay away from mobile phones when they have the chance to actually talk and communicate with others.
In a word, mobile phones act as an appropriate platform where people can always stay in touch, however long the distance is, but a wise man should know when to put down his phone.
范文十：A Harmonious Dormitory Life
Dormitory life is an indispensable part of college life. But sometimes the harmony in the dormitory will be disturbed in one way or another.
As is known to all, a harmonious dormitory life is important to college students and benefits all the members. On the one hand, we can have a good rest and put our heart into study. On the other hand, we will have a good mood and enjoy being together.
There are several ways to create and maintain a harmonious dormitory life. Firstly, you have to evaluate your lifestyle and try to get rid of your dirty habits, if there are any. Secondly, when an annoying situation arises, you'll just have to learn to tolerate each other and coexist. Thirdly, you'll have to share with each other and make good friends.
In conclusion, we should try our best to build a harmonious dormitory life for the sake of good study and good life.
范文十一：The Necessity of a Test of Spoken English
A test of spoken English will be included as an optional component of the College English Test (CET). Some people contend that it is absolutely necessary to hold a test of spoken English in China because we have been told many times that a Chinese student who has been learning"继续"这个词在很多情境下都有应用，它表示不中断地持续进行某个动作、活动或过程。以下是一些使用“继续”这个词的不同情境和例子：
工作和学习：
- “尽管遇到了困难，他还是决定继续努力工作。”
- “课程结束后，我们可以继续自学以深化理解。”
日常生活：
- “雨停了，我们可以继续我们的户外徒步旅行。”
- “电影中场休息后，观众陆续回到座位继续观看。”
体育和健身：
- “尽管比分落后，球队还是继续努力，最终赢得了比赛。”
- “在健身房锻炼了一个小时后，我决定继续跑步以加强心肺功能。”
项目和任务：
- “这个项目进展顺利，我们可以继续按照原计划进行。”
- “完成这项任务后，请继续处理下一个待办事项。”
故事和叙述：
- “故事继续发展，主人公遇到了新的挑战。”
- “小说进行到一半时，情节突然转折，但故事依然继续。”
情感和人际关系：
- “尽管我们之间有误会，但我希望我们能继续这段友谊。”
- “他们的关系经历了波折，但最终他们选择继续在一起。”
法律和程序：
- “听证会继续进行，双方律师都发表了各自的意见。”
- “尽管面临上诉，法庭的判决仍然继续有效。”
自然和物理过程：
- “地球继续自转和公转，带来了昼夜和四季的变化。”
- “化学反应继续进行，直到所有反应物都被消耗完。”
在这些例子中，“继续”都强调了不中断、持续进行的重要性。无论是个人努力、团队合作、日常生活还是自然界的规律，继续都是推动事物向前发展的关键要素。
