Question1: Where did you build or see a campfire?
Answer1: Two years ago I went to the school trip and in there we built a campfire.
(Don't worry, it's not dangerous!)
Question2: What did you make the fire with?
Answer2: We used some wood sticks, dry leaves, and of course we used matches to make a fire.
(These were the necessary items for us to make the fire.)
Question3: How did you put out the fire?
Answer3: Teachers put out the fire, because it is too dangerous to put out for students.
(*In here put out means extinguish.)
