With environmental damage from coal- and gas-derived power already at crisis levels, renewable energy sources are becoming more and more attractive. Wind power, one _______ 41 _______ and relatively cheap renewable energy source that contributes no toxic _______ 42 _______ to the environment, seems, to many of us, highly ideal.But there are some people who disagree and are against the installation of new wind turbines.

Through various forms of protests, they hope to express their concern and force change, so that birds could be saved from death caused by the _______ 44 _______ of wind turbine blades.No one really knows how many birds die each year as a result of the _______ 45 _______ wind power industry. Most studies focus on only one or two wind farms. Yet, published studies suggest that wind farms _______ 46 _______ considerably in the risk they pose to birds. Some wind turbines don't appear to kill any birds, while others are believed to kill as many as 40 birds per turbine per year.Though there is no denying that existing reports tell us little about the total number of birds killed each year, they do suggest one thing: Changes are being _______ 47 _______ to save birds from the rotary blades. For example, in some countries, it is required that wind farms should not be built on bird _______ 48 _______ routes, or in areas with high bird populations.

The notion that the great apes, such as chimpanzees and gorillas, can imitate one another might seem unsurprising to anyone who has watched these animals playing at the zoo. But in scientific circles, the question of whether apes really do “ape” has become controversial.Consider a young chimpanzee watching its mother crack open a coula nut, as has been observed in the Taï forest of West Africa. In most cases, the youth will eventually take up the practice itself. Was this because it imitated its mother? Skeptics think perhaps not. They argue that the mother’s attention to the nuts encouraged the youngster to focus on them as well. Once its attention had been drawn to the food, the young chimpanzee learned how to open the nut by trial and error, not by imitating its mother.What does the word “ape” (Para. 1) probably mean?A. Play at the zoo.B. Crack a nut.C. Imitate.D. Watch.
