Scientists at the Los Alamos National Laboratory have succeeded for the first time in mining heat from the Earth’s interior and producing energy on a commercial scale, enough for efficient generation of electricity and heating factories and homes. A. and producing energy on a commercial scale, enough for efficient generation of electricity and heating B. and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat C. for energy production on a commercial scale, enough for generating electricity efficiently and to heat D. to produce energy on a commercial scale, enough for generating electricity efficiently and for heating E. to produce enough energy on a commercial scale for efficient generation of electricity and heat 答案中解释: A: and没有平行的对象 B: 同上 C: production不如produce表达的清楚;for generating 和 to heat 不平行 D: correct E: generation 不如generating 表达的清晰;and heat应该和for平行而不是和to produce
注意: 1.名词形式和动词形式的比较,在表达动作本身而不是结果的时候应该用动词 2.To produce and heat 还是for generating and for heating,应该从逻辑意思判断 我选了E。答案解释中, generation 不如generating 表达的清晰。这个未必吧? 印象中只有动词原型是最清晰的。而且我觉得and heat 就是应该和produce平行-----to produce energy and heat factories and homes |
