For teenagers, growing up is a good thing, but it is also a painful experience in their lives. Many changes happen in those short years, including physical and emotional (情感的) changes. They will feel confused and afraid, and even lose confidence. Well, what are the changes?
Teenagers will find a lot of small changes in their bodies. There is an increase in height and weight, changes in voice, skin and so on. They begin to worry about all these changes in their bodies, and to check whether they are developing normally. They will continue comparing themselves with other teenagers.
In primary school, children usually wore what their parents gave them, and never thought about the style of the clothes. But now, they will think about how they look in others' eyes. They will have a strong wish to look good and be admired by others. And sometimes they will even have arguments with their parents about the clothes they should wear.
Teenagers hope to be accepted by others and want to have several true friends. Whether they are popular or not will become a very important part in their lives. Sometimes they will compare with each other to see who has the most friends.
However, as a teenager, whatever problems you have, remember to talk to your parents, teachers, friends or anyone that can share your worries and give you advice. Teenage life is a wonderful time. Enjoy it!
