　　阅读理解2017·烟台3月诊断性考试Fahad Azad，an engineer in India，invented a robot named DuctBot.The toy­car sized DuctBot measured 23 centimeters in length,19 centimeters in width and 9 centimeters in height and weighs just two kilograms.

　　The robot is designed to snake through dark，narrow air conditioning ducts (管道) and clean them.A pair of LEDs fitted on the robot light up the dirty scenery，so it can be captured (抓拍) by a camera.

　　In order to control it more easily，Mr Azad chooses to fix DuctBot on wheels.The robot can clean off lots of dirt，as well as dead pigeons and insects.Keeping indoor air in good quality and monitoring carbon­dioxide levels in buildings with central air conditioning is a challenge.It is important in some places where clean air can mean a difference between life and death，such as hospitals.Dirty air has a bad influence on people’s health.
