Many people think of guys as being carefree when it comes to their appearance. But in fact, a lot of guys spend plenty of time in front of the mirror.    1   .

Body image is a person’s opinions and feelings about his or her own body and physical appearance.     2   . You appreciate your body for its capabilities and accept its imperfections.

So, what can you do to develop a positive body image? Here are some ideas:

Recognize your strengths. Different body types are good for different things. What does your body do well? Maybe your speed, strength, or coordination makes you better than others at a certain sport. That may be basketball, table tennis, mountain biking, dancing, or even running. Or perhaps you have non-sports skills, like drawing, painting, singing, playing a musical instrument, writing, or acting.      3   .

Exercise regularly. Exercise can help you look good and feel good about yourself. Good physiques (体形) don’t just happen.     4   . A healthy habit can be as simple as exercising 20 minutes to one hour three days a week. Working out can also lift your spirits.

Respect your body! Practicing good habits --- regular showering; taking care of your teeth, hair, and skin; wearing clean clothes, and so on --- can help you build a positive body image.

   5     . Your body is just one part of who you are. Your talent for comedy, a quick wit (智慧), and all the other things make you unique. So try not to let small imperfections take over.

A.Use this as an opportunity to discover what you’re good at.

B.Be yourself.

C.They care just as much as girls do about their body image.

D.Just explore talents that you feel good about.E. They take hard work, regular workouts, and a healthy diet.
