根据短文回答 41～45 题。 More Than a Ride to, School The National Education Association claims, 'The school bus is a mirror of the community.' They further add that, unfortunately, what appears on the exterior (外部) does not always reflect the reality of a chosen community. They are right, and sometimes it reflects more! Just ask Liesl Denson. Riding the school bus has been more than a ride to school for Liesl Bruce Hardy, school bus driver for Althouse Bus Company has been Liesl's bus driver since kindergarten Last year when Liesl's family moved to Parkesburg, knowing her bus went by her new residence, she requested to ride the same bus.This year Liesl is a senior and will enjoy her last year riding the bus. She says, 'It's been a great ride so far! My bus driver is so cool and has always been a good friend and a good listener. Sometimes when you're a child adults do not think that what you have to say is important. Mr. Hardy always listens to what you have to say and makes you feel important.' Her friends Ashley Batista and Amanda Wolfe agree.Bruce Hardy has been making Octorara students feel special since 1975. This year he will celebrate 30 years working for Althouse Bus Transportation. Company President, Larry Althouse acknowledges Bruce Hardy's outstanding record. 'You do not come by employees like Bruce these days; he has never missed a day of work and has a perfect driving record. Recognized in 2000 by the Pennsylvania School Bus Association fer driving 350,000 accident free miles, Hardy's reputation is made futher evident through the relationships he has made with the students that ride his bus.'Althouse further added, 'Althouse Bus Transportation was established 70 years ago and has been providing quality transportation ever since. My grandfather started the business with one bus. Althouse Bus Transportation is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come.'Three generations of business is not all the company has enjoyed. Thanks to drivers like Bruce Hardy, they have been building relationships through generations. Liesl's mother Carol also enjoys fond memories of riding Bruce Hardy's bus to the Octorara School District. 第 41 题 The word 'mirror' in the first line could be best replaced by（ ）.A．'vehicle'B．'device'C．'company'D．'reflection'
