PREP 36

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 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:

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

heat有宾语应该是动词啊,E的generation和heat不对称啊,要是produce与heat对称的话

mining heat from the Earth’s interior to heat factories and homes,应该是生产出的energy去 heat吧
