单选题This is not a typical summer camp. But Michelle Pawlaw is glad she signed up for it. '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 28 in the three-day camp offered by the Arlington County Fire Department 29 just outside of Washington. Firefighter Clare Barley is in charge of the program. 'The purpose is to try to get young women interested in 30 the fire service as a career,' she said. The free of charge, overnight camp is designed to let the girls experience what 31 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, 32 emergency tools and rescue. They also do their share of cleaning the 33 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 34 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 35 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 36 on duty prepare for dinner. It is also part of the program. And, the girls say, by 37 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

单选题If you want to stay young, sit down and have a good think. This is the research result of professor Faulkner, who says that most of our brains are not getting enough exercise and as a result, we are ageing unnecessarily soon. Professor Faulkner wanted to find out why healthy farmers in northern Japan appeared to be losing their ability to think and to reason at a relatively early age, and how the process of ageing could be slowed down. He set about measuring brain volumes of a thousand people of different ages and occupations. Computer technology enabled him to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intelligence and emotion, and determine the human character. Contraction of front and side parts--as cells die off--was observed in some subjects in their thirties, but it was still not evident in some sixty- and seventy-year-olds. Faulkner concluded from his tests that there is a simple way to slow the contraction--using the head. The findings show that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Faulkner, are lawyers, followed by university professors and doctors. White--collar workers doing routine work are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant. Faulkner's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to maintain good blood circulation is through using the brain," he says. "Think hard and engage in conversation. Don't rely on pocket calculators./
