篇一：

　　Dear Anna,

　　I want to take this opportunity to inform you that Peter will be joining us shortly.He has worked in this field for twelve years and we are delighted that he has decided to join our company at this stage of our development.

　　He is a person of efficiency and responsibility and I have no doubt you will find a good partner in him.

　　Peter is currently involved in a project which might be of interest to you, and he shall be contacting you immediately after his arrival.I am sure it will be a happy and valuable experience for both of you.

　　Sincerely yours,

　　Henry

　　首段通告了Peter将要来到的消息，并对他做了简要介绍。次段继续介绍，并相信他将会成为收信人的好搭档。第三段说明了Peter将与收信人联系，并对双方的合作表达了信心。可以看出，这封信的写信人很可能是收信人的上级，所以行文不如上两封信那样客气。在上两封信中，写信人与收信人的关系都是平等的。

　　首段首句中的宾语从句中使用了将来进行时，请大家学习，第三段中也有这样的用法。次句中的stage表示“阶段”。第三段首句中的contact表示“联系”。次句中有形容词的平行用法。

　　此信的首段介绍了持信人与自己的关系，通报了其下月去收信人所在城市学习的消息。次段介绍了持信人的情况。第三段提出请对方担任持信人担保人的请求，并说明此举不会给对方带来任何负面影响。第四段是对对方的感谢和祝福。

　　首段的bearer表示“带信人，持信人”。第二段的accommodation表示“膳宿”。第三段的in case表示“万一”。
