In fact, a large scale HEP plant is capable of producing power more【33】______ than conventional sources, such as coal, oil and nuclear plants. Tidal power also compares【34】______ with nuclear and oil generated electricity, 【35】______ the amount of money on production. 【36】______ HEP stations, tidal constructions have a long life【37】______ . It is estimated that they can operate for over 100 years. With respect to【38】______ of supply, tidal stations【39】______ from HEP ones in that they often can only supply power【40】______.

选项
A、patterns
B、designs
C、plans
D、schemes
答案
C
解析
pattern图案;design设计图样;plan规划;scheme方案。这里指的是为潮汐电站做出规划,排除A和B项。虽然plan和scheme都有计划、方案的意思,但是plan还有“规划”的意思,即在某事真正进行之前已经详细考虑了实施步骤,故选C。
