答案
四、1.B 2.B 3.C 4.A 5.C
解析 1. 根据Energy Use表格中,空调(air conditioner)的日用电量是所有电器中最高的。故选B。
2. 根据Energy Flow表格中:wind → turbine → electricity → home(风→涡轮机→电→家)。故选B。
3. 根据Energy-Saving Tips表格中:Use LED lighting. (save 80% energy),LED灯可以节省80%的能源,故选C。
4. 根据Energy Facts表格中:Saving 1 kWh=planting 1 tree.。节约1千瓦时(1度)电相当于种植1棵树,故选A。
5. 根据Energy Facts表格中:Solar power, water power and wind power are clean, renewable energy.(太阳能、水能、风能是可再生能源。),太阳能(solar power)属于可再生能源,故选C。
