"Getting to experience the fires hands-on is really cool and something that most people don’t get to do," she said. Michelle and eight other teenage girls are 1 in the three-day camp offered by the Arlington County Fire Department 2 just outside of Washington. Firefighter Clare Burley is in charge of the program. "The purpose is to try to get young women interested in 3 the fire service as a career," she said. The free of charge, overnight camp is designed to let the girls experience what 4 do in the line of duty to protect the community. That includes some rigorous activities such as moving a fire victim. They take classes and learn how to climb the ladder on a fire truck, 5 emergency tools and rescue. They also do their share of cleaning the 6 and the equipment for an injured person. Firefighting is still a male-dominated service, but Burley says with 22 women on its force of 320 the Arlington Fire Department is above the national 7 of 4.5 percent. Burley joined the department seven years ago. "We do everything that the guys do to the same standard. We are tested to the same standard. We are 8 to operate at the same standard," she said. "We need to wash the lettuce and put it in a green big bowl," said Lieutenant Robert Beer. The girls help the 9 on duty prepare for dinner. It is also part of the program. And, the girls say, by 10 three days together, they also made new friends and had a lot of fun. A. located B. average C. almost D. operate E. expected F. firehouse G. crew H. greenhouse I. considering J. firefighters K. nearly L. cost M. participating N. imagined O. spending
