问题 Why are some major oil companies mentioned in the first paragraph?
What does the author mean by saying the "recent discoveries are modest"?
选项 A、People stop searching for oil.
B、People decrease the production of oil.
C、People use less oil than they used to.
D、The oil exploitation is limited.
答案D
解析 推理判断题。由题干中的recent discoveries are modest可定位至第二段倒数第二句。这里考查的是推断作者言外之意的能力，因此需要仔细阅读句子所在处的上下文，领会其真正含义。该段首句使用比喻，将探测原油比喻成钓鱼。如果很长时间都钓不到鱼，可以从两方面来分析：需要买价钱昂贵、采用新技术的鱼饵；池塘中大部分的鱼已经钓光了。接下来用石油进行对比：价钱上涨，新技术加以应用，但结果还是不行。在指出Recent discoveries are modest at best后，作者以具体事例说明其原因；尽管有些地方石油储备广泛，但开采原油需要消耗大量的天然气，丽后者的供应却不足。可见作者的言外之意是说由于客观原因导致石油开发量有限，造成石油生产量不能持续增加。该段末句提到将石油储备转化成原油的困难，但没有指明人们不再探测石油；从文中可以看出石油生产量达不到最高值，不是人们有意控制，而是客观条件不允许；句子上下文处没有提到有关石油消耗的问题。
