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
答案是D,可是我觉得E也有道理啊...因为可以把最后的"and heat"看作是和前面的to produce的搭配,而且逻辑上也讲得通:科学家们第一次成功地挖掘了地热,这些地热既能满足电力的产生,也能为工厂和家庭供暖...这样想不对么???请高手指点!!!谢谢
D:for generating electricity efficiently and
for heating
and 前后连接的部分要平行，D选项就平行，且意思比较好理解
1.原题",enough for efficient generation of electricity and heating."语法上and应连接两个并列的结构.而E中to produce 和heat 平行,改变了句子结构,从而改变了句意
2.enough for efficient generation of electricity and heating是表示to produce energy on a commercial scale 的用途所以for 后应接动名词 generating ,heating表示使用而不用efficient.heat状态性名词 表状态
3.enough位置改变修饰成分不同意思不同
谢谢各位指点,,,我的新理解:
如果选E,,,,逻辑上，因为是和produce搭配，因此统统无法享受enough for的概念，变成了：科学家发现了地热，首次能够heat factories & homes，和A的意思也相去甚远了。
