问题 The passage gives a general description of the benefits and potential problems of a hydrogen economy. [br] We must derive hydrogen from renewable sources with a view to a pure hydrogen economy.

选项 A、Y
B、N
C、NG

答案 A

解析 本题围绕氢的来源,因此锁定查找内容在Where does the hydrogen come from?部分。该部分中提到To have a pure hydrogen economy,the hydrogen must be derived from renewable sources…而with n 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。
