     No one wants to look silly or do the wrong thing at a new job. It is important to make a good impression

from the very first day. You will face new people. You will be in a new place. It may be difficult to know

what to do. We have some tips for you to make it through the first day at a new job:

     # First impression can last forever. Make sure you make a good impression. Before your first day, find

out if your new job has a dress code (rules about what you can wear to work). If so, be sure to follow it.

Remember always to be neat and clean.

     # Get to work on time. Give yourself an extra 15 minutes to make sure you arrive on time.

     # Pay attention to introductions. One of the first that your supervisor may do is to introduce you to co-

workers (同事). These co-workers will be important to you. They are the ones that will answer your questions

when the boss is not around.

     # Ask plenty of questions. Make sure that your supervisor has told you what is expected of you. If he or

she has not told you your duties, ask for a list. Set daily and weekly goals for yourself.

     # Never be the first to leave. Observe (观察) what your co-workers do around quitting time. It doesn't look

good for you to be eager (急切) to leave.
