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
(B) and producing enough energy on a commercial scale for electricity to be generated efficiently
(C) for energy production on a commercial scale, enough for generating electricity efficiently and to
(D) to produce energy on a commercial scale, enough for generating electricity efficiently and for
(E) to produce enough energy on a commercial scale for efficient generation of electricity and heat
这道题的讲解是说(A) have succeeded…and producing…前者是动词结构,后者是动名词结构不平行 可我觉得have succeed in mining and producing这样的意思是说 mining heat 和 producing energy是平行的 这样不对吗？ |
