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.

阅读下面短文，然后根据文章后的题目要求进行回答。
Sooner or later everyone has to write something－a thank-you note, a report at a meeting, a complaint or an apology．If you hate writing assignments in school, or if you still fear to put pen to paper, facing that empty page is almost as frightening as you’re facing a tiger．How to write it?There’s no mystery．Clear writing is just clear thinking．Here are some techniques for you．
Thinking on paper
Sit down with pencil and paper or at the computer screen and start outlining what you want to say, why it’s important, why it matters, and what its impact is on the reader．Just get the ideas down．The next step is to go back and put them in order．
Writing first sentence
Try to make your first sentence catch the reader’s eyes, because ________, the reader isn’t going to read on．Get a good, clear lead sentence that summarizes your points and that answers the reader’s question “What’s in it for me?” If you can’t do it in one sentence, then do it in two or three but keep them short．
Remembering the reader
Short, simple words are better than long words．Short sentences are better than long sentences．Remember that the goal is to communicate, not express yourselves．Most people are so devoted to what they want to say that they forget somebody else has to be able to read it．Too much information makes you lose readers before they get to the meat(某物之主要或重要的)of what you want to say．
Reading and rewriting
Read what you have written out loud, and listening for any awkward sentences．All good writers read, then rewrite．Back off a little bit from what you’re writing．It’s an old standard, but if you can, write something and come back a day late．
1．What is the best title for the passage?(Please answer within 10 words．)
____________________
2．Which sentence in the passage can be replaced by the following one?
Many writers just pay too much attention writing what they want but forget whether their readers can read it or not．
____________________
3．Please fill in the blank with proper words to complete the sentence．(Please answer within 10 words)
____________________
4．Which technique do you think is the best for you?Why?(Please answer within 30 words．)
____________________
5．Translate the underlined sentence in the first paragraph into Chinese．
