1In the United States people sometimes go camping for vacation． Instead of staying at modern hotels and restaurants，they live in the woods and do everything for themselves for a few days to relax．

When you are camping，you make all of your own food．It is rather like a large，many-day picnic．Barbeques(烤肉架) are very common while camping．You can bring meat and vegetables to the camp．To make a fire，you can find or bring your own wood and light it with a lighter(打火机)．

2Remember to put stones around the fire so that it won’t get too big and dangerous! When the fire is ready，you can cook food over it．Besides meat and vegetables，you can also cook marshmallows(果酱软糖) with the fire．

Children really like this activity at night．The whole family sit around the fire，eat marshmallows，and drink hot chocolate—especially when it is cold outside! Everyone can sing camping songs and dance together．

Camping is a fun activity for the family to do．Vacation does not have to mean going to visit faraway places，it could be as simple as setting up a tent in a nearby forest!
