Scientists at the Los Alamos NationalLaboratory have succeeded for the first time in mining heat
from the Earth's interior and producingenergy on a commercial scale, enough for efficient
generation of electricity and heating factories and homes.

(A) and producing energy on a commercialscale, enough for efficient generation of electricity and
heating
(B) and producing enough energy on acommercial scale for electricity to be generated efficiently
and to heat
(C) for energy production on a commercialscale, enough for generating electricity efficiently and to
heat
(D) to produce energy ona commercial scale, enough for generating electricity efficiently and for
heating
(E) to produce enough energy on acommercial scale for efficient generation of electricity and heat
B中producing和mining平衡，后句tobe generated 和 to heat 平衡，为何不选？

多谢你的解释啊。。原来是没有注意主语。。现在明白了~~

to heat 是修饰Scientists的，Scientists是 to heat 的逻辑主语，

Scientists (mine...and produce...) to heat... and for sth to be done（do

sth for sth to be done用法应该不合规矩，可能错在这里）
而句子愿意应该是Scientists mine...to(目的） produce energy（noun）+

enough for (noun modifier)

句义还是相当重要的，到底是否意思平行，就是靠句子判断

我觉得这题就是要你区分到底是平行还是目的

如果用producing的话，就是和mining平行。如此句子结构就变成

Scientists succeeded in minging heat and producing energy. ------平行的话也是share 相同的主语，再化简下就是：sb mine and produce，not makes sense

可是如果用to produce的话，就是Scientists succeeded in minging heat  to produce energy. 这个才是make sense.

所以个人觉得这里应该用”目的性的，而不是平行“，，只是想说当心”假平行“，平行需要”grammar，logic meaning“都平行才行

个人理解:  原句可以抽象为：sb. has succeeded for the first time (in

mining...) to do sth.

因为B中的to heat是修饰electricity，而文中的意思是修饰energy
