Помогите, пожалуйста, из этого огромного теста составить краткий пересказ на английском.
1) This is - Monday morning and while you dress , you look at yourself in the mirror. ' I'm too skinny . I would like to put a little weight and be a little higher and be more muscular, ' you think. ' I also would not mind a thicker hair , longer legs, the top teeth and a smaller nose. Talk about my nose , which is a pimple on it? Oh, here we go again ! I can not get out. I can not stand people staring at me. '
2) These observations seem familiar ? Almost everyone would want to change something about their bodies . Teens feel that way quite often, because their bodies are changing, while they grow. While your body is changing , too - the way you feel about your physical appearance . Your body image is often affected by the opinion you have of yourself.
3) As your body matures, you may think that it draws attention to you and you may feel uncomfortable. You can also compare themselves with their friends, to see whether you are normal . But cultivation occurs at the same speed for all . Girls usually start to change more than boys. Sometimes , they suddenly gain weight because their bodies need fat to grow . On the other hand , the boys noticed the shoulders , becoming wider and their voices becoming deeper . These changes usually take place over two - five years.
4) Images from the media TV, movies and advertising can also affect your self-esteem . Women and girls on TV and in magazines are usually thin, while men look strong and very muscular . It can make you believe that something is wrong with you if you do not look this way. Media images may also put pressure on you to stick to diets emergency or become obsessed with weight training . Remember that the more important exercise regularly and eat healthily than to try to change your body to fit the image unrealistic . Ads selling fantasy and vanity , not reality .
5) Although you may often think your classmates notice every pimple on your face or every pound you gain is not the case . What they notice - how you feel about yourself . You should focus on the things that you like about yourself and walk with confidence! If you like yourself and the way you look , then other people will too!-
