小题1:  _ One of the best things you can possibly do is to start you own club. It’s great fun especially if you are the sort of person who feels there’s never anything to do during the school holidays.

The first thing you need to come up with is an idea for your club.  _小题2:  _ Pets, clothes, pop music or dancing groups, sports, making things? The list is endless.

Next you need some friends to be in your club with you.  小题3:  _ All you need is three or four other people who are interested in the same thing as you.

 小题4:  You should all sit down somewhere together with lots of pieces of paper and write down every name you can think up. That’ll keep you busy for ages.

Now you have just about everything you need, except membership cards. These are very important and again you can speed a lot of time making them.  小题5:      Why not leave some space for a photo of yourself? That will make the membership card really look like it.
