问题 The author of the passage is primarily concerned with______.
It can be inferred from the passage that a vehicle specifically designed to use methanol for fuel would______.
选项 A、be somewhat lighter in total body weight than a conventional vehicle fueled with gasoline
B、be more expensive to operate than a conventional vehicle fueled with gasoline
C、have a larger and more powerful engine than a conventional vehicle fueled with gasoline
D、go average more miles per gallon than a "gasoline clone" vehicle fueled with methanol
答案D
解析 推断题。题意为："从文中可推断一辆专门设计使用甲醇的汽车______"。根据文章末段可知，一辆专门设计使用甲醇的汽车要比一般燃汽油的汽车使用甲醇的效率高得多，因此用的燃料相对较少。因而选项"每燃烧一加仑甲醇的英里数要多于一般燃汽油汽车使用一加仑甲醇的英里数"为正确答案。
