求問67題....
67.Several industries have recently switched at least partly from older technologies powered by fossil fuels to new technologies powered by electricity. It is thus evident that less fossil fuel is being used as a result of the operations of these industries than would have been used if these industries had retained their older technologies.
Which of the following, if true, most strengthens the argument above?
A. Many of the industries that have switched at least partly to the new technologies have increased their output.
B. Less fossil fuel was used to manufacture the machinery employed in the new technologies than was originally used to manufacture the machinery employed in the older technologies.
C. More electricity is used by those industries that have switched at least partly to the new technologies than by those industries that have not switched.
D. Some of the industries that have switched at least partly to the new technologies still use primarily technologies that are powered by fossil fuels.
E. The amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount that would have been used to power the older technologies.
我主要想請教的是,正確答案E選項暗示說新的科技使用電來產生power所用到的fossil fuel比老科技的方法用的少,所以增強了論點:fossil fuel用的少了....到底要怎樣的腦力可以想到說改成新方法了還要用到fossil fuel啊?!畢竟我一看完題目就覺得一翻兩瞪眼就是用電歸用電 用油歸用油........................................
B在我看來是賣弄 manufacture the machinery 第一遍看過去我只看到我想看的,但其實這感覺是製造那台機器(?)
我真正有大問題的是D為何不行!
如果這些改用新科技的工廠大部分還是用老科技來產power,那fossil fuel還是會用的比較少啊....為什麼錯...
希望有神人可提點,感恩
