阅读下面短文,并根据短文后的要求答题(请注意问题后的字数要求)。

     Even if you really enjoy your job, it's still possible to battle boredom as you work. You may not be able to

make big changes-or change your job-but you can make small adjustments to your routine that can make every

day seem, well, a little less routine.

     1. Switch Your Seat

     Change your outlook at the office by changing your office. Ask your supervisor to help you find a new desk.

Even switching desks with a neighboring co-worker can offer a fresh atmosphere.

     If it's not possible to change your location, see if you can change your desk's direction. A new view can be

just as refreshing as a new location.

     2. _____

     Start and end your day in a different way. Consider a new mode of transportation, if it's possible. Take a

subway. Ride a bike on sun- ny days. Carpool with a co-worker. Use a new route to get to your job. You needn't

change it for ever-just long enough to help you escape the boredom.

     3. Find a New Work Style

     Sick of attending that long-standing Monday morning meeting? Try to change it to the afternoon.

     If you find yourself feeling most bored in the afternoons, try to arrange to do your favorite tasks then and

tackle less desirable projects in the mornings.

     If you usually communicate with co-workers via email and instant messaging, start dealing with people face

to face. Increased communication with co-workers may help improve your mood.

     4. Get and Set a Goal

     If your work is short of objectives, it's no wonder that work has become boring. Identify a goal and set an

"achieve by" date for it.

     Your goal needn't be lofty as long as you have sufficient enthusiasm for it. Perhaps you want to make a new

project. Maybe you'd like to pursue a promotion. Or you may even set a goal of finding a new job altogether.

Whatever it is, actively move toward an objective.
