　 For years scientist have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more 　　41　 　than the air outside. It may be one hundred times worse.

　 Indoor air pollution can cause a person to feel tired, to 　　42　　 　eye-pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists 　　43　 　that every modern house has some kind of indoor pollution. People began to 　　44　 　the problem in the early 1970s, when it was that builders began making houses and offices which did not waste energy. To do this they built buildings that 　　45　 　the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to 　　46　 　harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control 　　47　 　for building green plants. Scientist do not really know how plants control air pollution. They believe that a plant’s leaves take in the pollutants. In exchange the plant produces oxygen 　　48　 　its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each 　　49　 　different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.

Good news! Tiny robots designed by University of Nebraska researchers may 　50 　　　doctors on Earth to help perform surgery on patients in space.

　 The tiny, wheeled robots, which are about 3 inches tall and as wide a lipstick case, can be slipped into small incisions ( 切口 ) and computer-controlled by surgeons in different 　　51　 . Some robots are equipped with 　　52　 　and lights and can send images back to surgeons and others have surgical tools attached that can be controlled 　　53　 .

　 “ We think this is going to 　　54　 　open surgery.” Dr. Dmitry Oleynikov said at a news conference. Oleynikov is a 　　55　 　in computer-assisted surgery at the University of Nebraska Medical Center in Omaha.

　 Officials hope that NASA will teach 　　56　 　to use the robots soon enough 　　57　　

surgeries could one day be performed in space.

　 The camera-carrying robots can provide 　　58　 　of affected areas and the ones with surgical tools will be able to operate inside the body in ways surgeons’ hands can’t. The views from the camera-carrying robots are 　　59　 　than the naked eye, because they 　　60　 　back color images that are magnified. Because several robots can be inserted through one incision, they could reduce the amount and 　　61　 　of cuts needed for surgery, which would decrease recovery time. This is particularly 　　62　 　to those patients who have been weakened by long illness.

　 Eventually, Oleynikov said, “ The tiny robots may enable surgeons to work without ever __63__their hands in patients’ bodies. That is the 　　64 　. It is getting easier and easier. We can do even more with these devices.”
