Q: Article: Fahad Azad, an engineer in India, invented a robot named DuctBot.The toy-car 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 and clean them.A pair of LEDs fitted on the robot light up the dirty scenery, so _ can be captured 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 carbon-dioxide 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. EPSCO, a Dubai-based company which specializes in improving indoor air quality, read about Mr. Azad's invention in a national newspaper after he had won an international robotics competition.EPSCO had cleaning equipment, but it needed someone to get into those ducts to do the dirty, dangerous work.Across India, for example, the task still falls to children.They are small enough to go through those ducts. In 2005, Mr. Azad who was still at university decided to do something about it.Six years later his own company, Robosoft Systems, has Bluestar, EPSCO and the Indian Navy, some leading air condition makers, as partners. Mr. Azad and his ten employees are currently exploring robot designs to examine oil tanks or sewage pipes.Their biggest challenge is to make the robots user-friendly enough.Mr. Azad hopes that the robot could eventually be operated not by engineers but by workers.There will be lots of difficulties they need to overcome in the future.
Answer: It is designed to move like a snake in the ducts.

Q: Article: There is an English saying, "Laughter is the best medicine." Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people's health. Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial. Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programmes. The group that tolerated the pain for the longest time was the group which listened to a funny programme. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which _ both stress and pain. As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.
Answer: Laughter can make you become old quickly.
