Scientists found that by combining fans and AC， it’s possible 63 （keep）human comfort indoors while reducing reliance on AC. If it was ud in Australia， the yearly emissions and cost could 64 （cut）by 70 percent.
The model they created to compare energy u and emissions employed five 65 （programme）. One ud just air conditioning， and 66 other four had fans at different speeds and the u of AC only when the temperature 67 （get）too high. By modeling temperature data for the whole Australia， they found the one with the fastest fan 68 （produce）airspeed flows of 1.2 meters per cond had a reduction of 76 percent in energy usage.
Co-author Professor Ollie Jay said，“By increasing air movement with fans， you can feel the same at a higher temperature 69 you will do at a lower temperature using AC. This is 70 most people can do to reduce the emissions in Australia.”

Doug Tallamy，洒脱的英文 64 professor of entomology（昆虫学）at the University of Delaware， found that non-native plants can harm the 65 （nature）food chain， leading to breakdown of the environment.“Plant choice matters，”he said.“The plants we choo should 66 音乐的英文（determine）by how much life can live there.”

Humans depend 67 （strong）on incts. Without them， we would have no flowering plants， 68 would harm the food web that supports important animals. Birds， for example， depend on plants for food and spread their eds while 69 （keep）the populations of harmful incts down.福州托福一对一辅导
In addition to providing food and habitat for birds and incts， native plants are able 70 knife是什么意思>january（survive）easily and don’t require much care.
