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
问：为什么讲A的前半部分中的have succeeded…and producing…进行比较？可不可以理解将in mining和producing进行比较？可以理解为成功的减少热量和产生足够的能量?
