当窗体大小改变时，要使其中的控件也按比例发生变化，应使用窗体的是______A．Au

   The purpose of a letter of application(求职信) is to help you to "sell" yourself. It should state__1_
the    job you want, and should tell what your abilities are and what you have__2_. It should be simple,
human,  personal and brief without _ 3 _ out any necessary facts.
   In writing a letter of application, keep in __4__ that the things a possible employer is most _5__ to
want to know about are your qualifications(条件), your achievements and your aims. The opening
paragraph is perhaps the most important part. _6__ the first few sentences fail to _7__ the reader's
attention, the rest of the letter may not be __8_ at all. Try to key your opening remarks to the needs
or interests of the employer not __9_ your own need or desires. For example, instead of beginning
with "I saw your _ 10_ in today's newspaper," you might say "I have made a careful _11_ of your
advertising during the past six months" or "I have made a survey in my neighborhood to find out how
many housewives _12_ your product and why  they  like it. "
   Try to _13_ generalities. Be clear about the kind of job for which you are now _14_. College
graduates  looking for their first positions often ask "What can I _15_  in a letter? Employers want
experience-which, naturally, no ___16___ has." The answer is that everything you have ever done
is _17_.
   It is important to write a good strong closing for your letter. _18__ a specific request for an interview
or give the possible employer something definite to do or expect. An excellent  _ 19_ is to enclose
(内附) a stamped, self-addressed envelope with your letter. That makes it _ 20_ for a possible employer
to get in  touch with you.
