阅读下面的短文,并根据短文后的要求答题

     With many job postings(公开招聘) now requiring candidates (应聘者) to apply via e-mail, first impressions

are made not with a handshake but with words on a computer screen.

     Just like it's usually a good idea to dress best for an interview, e-mails also should be refined. _____, here

are some tips:

     ☆Forget what instant messaging has taught you.

     Recruiters (招聘人员) report that young professionals often send overly casual e-mails, treating an

application like an instant message (IM). When using IM with friends and acquaintances, it's acceptable to use

shortened forms of words or phrases and incomplete sentences. In business correspondence (信函), however,

stick to the rules your Chinese and English teachers taught you.

     ☆Don't be cool.

     Your lovely e-mail background of pets playing with each other has got to go. Comic fonts (字体) are

unprofessional. HR managers (人力资源经理) recommend plain fonts such as Times New Roman or Arial,

and black text on a white background. They also warn against sending e-mails from strange addresses.

Littlebird@ or Chinatiger@ might not get what you hope for.

     ☆Don't be too creative in the subject line (标题).

     Use plain, simple language like "Talented candidate seeking position as [name of position]" or"Enthusiastic

candidate seeking position with [name of company]". Use one word to describe yourself, but do not go to

extremes.

     The same rules apply to a paper resume (简历) and cover letter. Recruiters have only seconds to devote

to each cover letter they receive. Many look at just three things: the positions you've held, the companies

you've worked for,and your educational background. Anything else, such as a long story about yourself, can

get in the way.
