Everybody has their own hobbies—some are fond of collecting

Everybody has their own hobbies—some are fond of collecting stamps,coins,etc.,some like swimming,and there are some who like reading or music—all these are good hobbies.
Nowdays,most teenagers are crazy about hit songs.From those songs we can learn many phrases,which we cannot find in books.Although teenagers like those songs very much,abults often dislike them.And they think that if teens indulge(沉迷）themselves with pop music,it will be a waste both of time and money.Therefroe,it is not considered to be a good hobby.
The worst hobbies of all are smoking and gambling.Smoking harms our bodies.Some men like to smoke in public places,and they don't care about other people's feeling.Gambling may make you lose everyting.You may lose your temper,money and friendship.Friendship is the thing that money can't buy.To lose a friend is easy but to build up a friendship is hard.
So,why don't we do thing that can't hurt others and are worthwhile to us?Some good hobbies,like stamp collecting and reading,can help us broaden our knowledge.Music can make us happy,and sports can keep us in good physical condition.So why not take up the good and give up the bad?
