[語文] PP SC 44
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.)
(D) to produce energy on a commercial scale, enough for generating
electricity efficiently and for heating
我想問的是:enough for Ving 這是OK的嗎?
練習時因為認定enough to 原形V 是一個規則而沒選(D)
希望達人可以指教一下吧!
快考試了!
