问题 The passage gives a general description of the benefits and potential problems of a hydrogen economy.
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。
