问题 The passage gives a general description of both the advantages and disadvantages brought by a hydrogen economy. [br] 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。
