Dear Mr.Williams，
Your advertisement in this morning’s paper for manager of public relations appeals to me.I found the wording of your advertisement quite attractive with emphasis on leadership，initiative，and flexibility.And my experience and qualifications indicate that I am the person you are seeking.
The enclosed resume indicates my experience in the area of public relations and management communications. I am quite familiar with the kinds of issues and problems that you have to deal with.
I’d like to draw your attention to page 2 of my resume，on which I describe my concept of public relations. And I am most eager to put this concept into practice to prove it to you.
Although I have been very happy with my present employer and colleagues，I am more willing to join your company where I can assume even broader responsibility.
I am free to travel and open to relocation.I would welcome the opportunity to meet you and to further discuss how I may benefit your organization.Please call me at 0411—89726374 to arrange an interview at your earliest convenience.
Sincerely yours,
Stephen Smith

1. “The Nobel Prize in Physiology or Medicine 2004”Press Release(15分)
4 October 2004
The Nobel Assemblyat Karolinska Institutet has today decided to award The Nobel Prize in Physiology or Medicine for 2004 jointly toRichard Axel and Linda B. Buckfor their discoveries of "odorant receptors and the organization of the olfactory system"
Summary
The sense of smell long remained the most enigmatic of our senses. The basic principles for recognizing and remembering about 10,000 different odours were not understood. This year's Nobel Laureates in Physiology or Medicine have solved this problem and in a series of pioneering studies clarified how our olfactory system works. They discovered a large gene family, comprised of some 1,000 different genes (three per cent of our genes) that give rise to an equivalent number of olfactory receptor types. These receptors are located on the olfactory receptor cells, which occupy a small area in the upper part of the nasal epithelium and detect the inhaled odorant molecules.
Each olfactory receptor cell possesses only one type of odorant receptor, and each receptor can detect a limited number of odorant substances. Our olfactory receptor cells are therefore highly specialized for a few odours. The cells send thin nerve processes directly to distinct micro domains, glomeruli, in the olfactory bulb, the primary olfactory area of the brain. Receptor cells carrying the same type of receptor send their nerve processes to the same glomerulus. From these micro domains in the olfactory bulb the information is relayed further to other parts of the brain, where the information from several olfactory receptors is combined, forming a pattern. Therefore, we can consciously experience the smell of a lilac flower in the spring and recall this olfactory memory at other times.
Richard Axel, New York, USA, and Linda Buck, Seattle, USA, published the fundamental paper jointly in 1991, in which they described the very large family of about one thousand genes for odorant receptors. Axel and Buck have since worked independent of each other, and they have in several elegant, often parallel, studies clarified the olfactory system, from the molecular level to the organization of the cells.
