单项选择题
完形填空

  The purpose of a letter of application is to help you to “sell” yourself. It should state  36 the job you want, and should tell what your abilities are and what you have  37  . It should be simple, human, personal and brief without  38  out any necessary fact.

  In writing a letter of application, keep in  39  that the things a possible employer is most 

 40  to want to know about are your qualifications(条件), your achievements and your aims.The opening paragraph is perhaps the most important part. 41 the first few sentences fail to  42  the reader’s attention, the rest of the letter may not be  43  at all. Try to key your opening remarks to the needs or interests of the employer not  44  your own need or desires. For example, instead of beginning with “I saw your  45 in today's paper. ”you might say“I have made a careful  46  of your advertising during the past six months” or “I have made a survey in my neighbourhood to find out how many housewives  47 your product and why they like it.”

  Try to  48  generalities. Be clear about the kind of job for which you are now  49 . College graduates looking for their first positions often ask“ What can I  50  in a letter? Employers want experience, which, naturally, no  51  has. ”The answer is that everything you have ever done is  52 .

  It is important to write a good strong closing for your letter. 53  a specific request for an interview or give the possible employer something definite to do or expect. An excellent 54  is to enclose(内附)a stamped, self - addressed envelope with your letter. That makes it  55  for a possible employer to get in touch with you.
