    正确答案： 【参考范文】
    To: Mr. Walker, Human Resources Director
    From: Zhang Gao, Translating Coordinator
    Date: May 16, 2012
    Subject: Management Skills Most Suitable for Foreign Language Translators
    The Company has planned three training courses for all foreign language translators for the next three months and I have been required to recommend one course as being the most suitable.
    The three courses from which a choice may be made are as follows:
    (i)English Language Development; (ii) Changes in Technology; (iii) Management Skills.
    All translators in the Company have college degrees in English Language and a lot of colleagues in our field have postgraduate qualifications in Translation or Linguistics. Since English Language Training Course of the Company is only to Diploma level and contains nothing new to us, it is not useful for us and is best left to other colleagues.
    Two months ago all Company’s translators finished an excellent “Changes in Technology” course, which brought us up-to-date information on use of machine translating and personal computers. Obviously, there is no need for us to attend the “Changes in Technology” course again.
    Undoubtedly the “Management Skills” course is the best choice for the Company’s translators. Recently it has been announced that next year our department will be divided into four sections, each of which will serve a specific division of a much-expanded Company. We will recruit twenty new English Language graduates as new translators, five to each section. We four existing translators will be promoted as Heads of Section.
    All four of us are shortage of management skills and, when we manage our own sections, such skills will be indispensable. As a result, I will recommend without hesitation that all translators be enrolled for the “Management Skills” training course.
