1、2015届高考考前热身专练：新闻报道类阅读1、We might not be alone in the universe. Actually, it may be confirmed as a very crowded place by new computer models developed to help identify habitable planets.Estimates of places where life can exist have been based on the possibility of them having surface water. But softwa
2、re recently developed by the Aberdeen University allows researchers to identify planets with underground water kept liquid by heat from planets.Water is fundamental for life and planets too close to the sun lose water to the atmosphere through evaporation. On the other hand, planets located in dista
