考研英语必背的20篇范文可能因年份、考试要求以及个人学习重点的不同而有所差异。以下提供几篇具有代表性和广泛认可度的考研英语作文范文，供考生参考和背诵：
范文一：辞职信
Dear Mr. Wang,
I am much grateful to be employed by you two months ago as an editor for your magazine, Design & Fashion. I appreciate the opportunity of having worked here with you and other colleagues. The experiences will be unforgettable throughout my life.
However, as a young man whose primary interest is in computer science rather than fashion designing, I find my present job doesn't fall in with my previous training and strength. I therefore decide to quit this job for something else that may conform to my former preparation.
Please accept my sincere apologies for any inconvenience my leaving may cause.
Yours truly,
Li Ming
范文二：希望工程捐款信
Dear Sir or Madam,
Moved by the noble cause of Project Hope and encouraged by what has been achieved so far, I would like to contribute my bit to the project by offering financial aid to a child in a remote area of your province. I would be much grateful if you could help me seek out a girl who has just started schooling but whose family cannot afford her education. My plan is to pay for her tuition on an annual basis till she finishes her secondary education. I would like to remit my donation directly to a bank account opened by her family in her local area.
Yours truly,
Li Ming
范文三：图书馆建议信
Dear Sir/Madam,
I am a student in this university who regularly comes to the library to spend my spare time. Generally speaking, the services you offer here are quite good; however, I have some suggestions for you to adopt. And I would like to extend my greatest appreciation if you are so kind as to take my suggestions into consideration.
To begin with, will you please prolong the time for reading? In the daytime, most of the students are having class, so they can't come to the library. Moreover, some of the books on shelves are out of date. If you are so kind as to provide us some books such as the latest magazines, we will be very pleased. I really wish to have a more comfortable library.
Thank you for your time and consideration.
Sincerely yours,
Li Ming
范文四：道歉信
Dear Bob,
I am writing to make an apology to you for I forgot to return a music CD which I borrowed from you last week. Yesterday I have come back from Canada and I found it in my luggage. I am so sorry that you cannot listen to it at present.
The CD which I borrowed from you is made in Canada, so I believe you can find another one in your local store. How about your buying another CD by yourself and I will pay for it? If you cannot find the similar one, I would send it back to you through a post office. And if there are any other solutions you like, please let me know.
I am sorry again for my carelessness. Looking forward to your reply.
Yours sincerely,
Li Ming
范文五：关于“白色污染”的观点
Dear Editor,
I'm a sincere reader of your newspaper and I like your discussion of the social problems. Now I would like to give some opinions of myself about the "White Pollution".
As we know, regulation was made to solve the problem in June 1st of 2008. The use of plastic bags for free was restricted in the supermarket and many other shops. At the beginning, it was carried on well, but now I find plastic bags are used in some small shops for free or with no pay.
I am writing to inform you that we should solve this...
（注：此篇范文未完整，但结构清晰，开篇点明主题，提出自己对“白色污染”的看法，接下来可以进一步阐述具体观点和解决方案。）
以上五篇范文涵盖了考研英语中常见的应用文体裁，包括辞职信、捐款信、建议信、道歉信以及观点阐述等。考生可以根据自己的实际情况和学习重点，选择适合自己的范文进行背诵和练习。同时，也可以结合其他范文资源，进一步丰富自己的写作素材和表达方式。
