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
这边to produce前面并没有对应的东西平行啊。。。
句子意思:科学家成功从地球内部获取热量,这些热量可以生产大量能量,这些能量足以用来发电和为工厂&家庭供热;所以,发电和为工厂&家庭供热应当是平行的。误选B,B项中to heat 跟to be generated 平行,使得to heat 的逻辑主语变为electricity,而electricity不能为家庭供热,所以B错。
