填空题

Dear Sirs,
For the past 8 years I have been a statistician(统计员) in the Research Unit of Baron & Smallwood Ltd. I am now looking for a change of employment which would broaden my experience. A large and well-known organization such as yours might be able to use my services.
I am 31 years old and in excellent health. I majored in advertising at London University and I am particularly interested in work involving statistics(统计).
Although I have had no experience in market research, I am familiar with the methods used for recording buying habits and trends. I hope that you will invite me for an interview. I could then give you further information.
I am looking forward to hearing from you soon.
Yours faithfully,
Mike Smith
