考研英语中小作文涉及的比较重要的三类：感谢信、祝贺信、邀请信。今天小编给大家介绍这三类常考到的文体。
一、感谢信
感谢信是对收信人的帮助、慷慨和款待的感激之情。在这一类型的内容中，主要是表达感激之情并说明原因；简单阐释自己受到的帮助；再一次表达感激之情。涉及到的感激类的话语比较多，要多积累一些并记忆。第一段首先致谢：I am writing to extend my heartfelt thanks to you for your you have offered me during 时间+地点。If it had not been for your timely assistance in giving me first aid, I fear that I might have been encountered much more serious problems.
第二段简单阐释自己曾经受到的帮助并想要回报：It is your that has enabled me to .Everyone agrees that it was your that has led me to
.If there were more people like you, the world would be a much nicer place. I hope to see you some day so that I may have the opportunity to do something in return for your kindness.可以根据自己的具体情况给出感谢的理由，切不可千篇一律。
第三段再一次表达感激之情：Again, I would like to express my thanks from the bottom of my heart. Please accept my gratitude.
二、祝贺信
祝贺信是对收信人在某方面取得成功或可喜可贺的事情进行的道贺，还会表达祝福及期望等。第一段说明事由并表达祝贺：I'm writing to convey my warm congratulations on your graduation /promotion/ admission. Your own intelligence and diligence have earned you this achievement.
第二段展开事件，赞扬收信人的能力及取得成功的原因，并展望他的未来的美好前景。I must say that I was not surprised to hear this good news. I know how industrious and perseverant you have always been in order to realize this dream. I'm delighted that your hard working has finally been rewarded. It is obvious that you will have a wide-open future ahead of you.
第三段再次表示祝贺：Again, congratulations and best wishes for your future life and work.
三、邀请信
邀请信涉及的场景比如参加聚会、共度假期、来访故乡等。第一段表明写信的目的；受邀人要参加的活动的时间地点；表示对对方到来的期待：I am writing this letter to invite you to .活动时间地点。We would be honored to have you there with us.
第二段详述活动安排。对于邀请的不是很熟悉的人要简单赞美一句。接下来叙述一天的活动安排：开始、中间、结束或者对于一段时间的安排：介绍家或家乡、去哪里游玩的安排。
第三段表明希望对方能来，再一次诚挚的邀请，并期待回复。If you don't have any prior appointment on时间，I will look forward to your arrival. Before you come, please give me a call. I will wait for you . I really hope you can come.
同学们可以往空白或具体内容中添加，进行练习，并进一步熟悉这几类小作文类型，祝大家考研顺利！
