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 |
