     In the United States, people like going camping for vacation. They do everything for themselves to

relax in the woods instead of staying at a modern hotel or a restaurant. They enjoy themselves far away

from the noisy cities for a few days.

    What should you prepare if you want to go camping like them? When you are camping, you make

all of your own food. Barbeques (烤肉架) are very necessary while camping. You can bring bread,

drinks, meat and vegetables to the camp. You'd better bring some wood and a lighter (打火机) to

make a fire. Remember to put stones around the fire to make sure it won't get too big and dangerous.

When the fire is ready, you can cook food over it.

     Children really like this activity at night. The whole family sit around the fire, eat their favorite food.

Certainly they can sing songs and dance together. What a pleasant and exciting moment.

     Camping is a fun activity for the family to do. Vacation does not have to mean going to visit a place

far away. It could be as simple as setting up a tent in the nearby woods.
