The passage gives a general description of both the advantages and disadvantages brought by a hydrogen economy.
We must derive hydrogen from __________________ with a view to a pure hydrogen, economy.
选项
答案
renewable sources
解析
本题与氢的来源有关,从而将目标锁定在Where Does the Hydrogen Come From?下。该部分倒数第二段第二:句提到To have a pure hydrogen economy,the hydrogen must be derived from renewable sources…。with a view to 与 to have…都表示目的,原句用了被动语态,而题干转换成了主动语态。
