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.
and producing energy on a commercial scale, enough for efficient generation of electricity and heating
and producing enough energy on a commercial scale for electricity to be generated efficiently and to heat
for energy production on a commercial scale, enough for generating electricity efficiently and to heat
to produce energy on a commercial scale, enough for generating electricity efficiently and for heating
to produce enough energy on a commercial scale for efficient generation of electricity and heat
找到正确的平行关系，最后两个动作（ generating electricity，heating factories and homes）是平行的，正确D，错选B，分析B/D：producing enough energy和mining heat 是并列关系还是有逻辑关系，答案是有逻辑关系更优，开采热量以生产足够的能源
Takeaway:
1.动名词和名词不平行
2.表示目的时,to do结构比for doing结构更有效.因为enough for doing，for doing表用途，如The knife is used for cutting things
3.mine heat的目的是为了produce energy，两个动词不应该是and连接平行的关系。逗号后面形容词enough作状语，就近修饰produce energy这个动作
sth is big enough to do sth, 足够/而能;
sth is enough to do sth/for doing sth，某物对于做……是足够的
带回原文读一下！名词配动词
逗号后面形容词作状语，就近修饰produce energy这个动作
to produce energy on a commercial scale, enough for generating electricity efficiently and for heating
前半句是平行还是修饰不好判断，先看后半句
A、简单,n.配动名词，不平行
B、名词（electricity）配动词（to heat），不平行
C、动名词配不定式，不平行
E、名词配动词，不平行
句子层次要搞清楚
mine和produce之间存在逻辑关系，并非并列！
mining heat 和produce energy并不独立，后者是前者的目的。
generating和heating平行
找到正确的平行关系
快速的找到选项间的差异
前面如果and的话，后面两个明显是修饰produce energy的，不合适。
只用平行即可
🐎一下：
enough的用法：
sth is big enough to do sth, 足够/而能;
sth is enough to do sth/for doing sth，某物对于做……是足够的
B/D：producing enough energy和mining heat 是并列关系还是有逻辑关系，答案是有逻辑关系更优，开采热量以生产足够的能源
在进行到选项二选一后，快速找到选项间差异的能力对于提高答题准确率还是很重要的。
当时在D和E中纠结，E中and前后不平行，因为从最后可以看出heat是个动词，and前边无动词，所以平行，最后选D
enough的用法：
sth is big enough to do sth, 足够/而能;
sth is enough to do sth/for doing sth，某物对于做……是足够的
B/D：producing enough energy和mining heat 是并列关系还是有逻辑关系，答案是有逻辑关系更优，开采热量以生产足够的能源
在进行到选项二选一后，快速找到选项间差异的能力对于提高答题准确率还是很重要的。
从地球内部开采热能用来生产能量，mine heat的目的是为了produce energy，两个动词不应该是and连接平行的关系。后面的发电和为家庭及工厂供暖二者平行修饰energy。
B选项说的是电用来供暖，语义上有问题，应该是energy用来供暖。
错选B，将mining和producing看作平行，将electricity看作核心词，实际上核心词应该是energy
正确选项为D，核心词为energy，用energy来发电、供热
enough for doing，for doing表用途，如The knife is used for cutting things
C，Scientists are successful in mining heat to produce energy on a commercial scale, enough for generating electricity efficiently and for heating factories and homes.
逗号后面形容词作状语，就近修饰produce energy这个动作
形容词作状语：Happy about his birthday, Joe made a cake for his family.
形容词作同位语：People, old and young, took to the streets to watch the parade.
