2018考研英语复习已经进入了攻坚阶段，这一阶段首要的的任务就是考研英语阅读真题的精析。考生需要将每一道题目的类型，定位方法，解题思路及选项特点分析清楚，尤其是对于一些难点题目。因为考研英语的学习是一项精细化的工程，必须吃透文章和题目。今天我们要分析的题目来自于2006年考研英语真题阅读Text3。文都考研老师将定位范围和题目对应给出，方便考生清楚的理解。 31.The extinction of large prehistoric animals is noted to suggest that.
[A] large animals were vulnerable to the changing environment
[B] small species survived as large animals disappeared
[C] large sea animals may face the same threat today
[D] slow-growing fish outlive fast-growing ones
定位解析：题干问大型史前动物的灭绝被提到是为了什么？这是一道例证题，应该遵循例证的做法去找例子的目的。因为文章开篇一直就在说史前动物的现象，所以例证的目的应该往后找，在首段的结尾处Now something similar could be happening in the oceans.“现在，类似的事情可能正在发生在海洋里。”类似的事情指的就是史前动物灭绝的事情，说明作者下文要谈及的是大型海洋动物也面临着灭绝的危险。所以答案选择[C] large sea animals may face the same threat today“大型海洋动物面临着同样的威胁”。[A] large animals were vulnerable to the changing environment“大型动物容易受到变化的环境的影响”。原文说的是灭绝问题，并不是环境变化。[B] small species survived as large animals disappeared“小的物种生存下来了而大的物种灭绝了”，该细节符合原文但是并不是例证的目的所在。 32.We can infer from Dr.Myers and Dr.Worm’s paper that.
[A] the stock of large predators in some old fisheries has reduced by 90%
[B] there are only half as many fisheries as there were 15 years ago
[C] the catch sizes in new fisheries are only 20% of the original amount
[D] the number of large predators dropped faster in new fisheries than in the old
定位解析：题干问从两位博士的论文当中可以推断出什么？找到论文的内容出处：According to their latest paper published in Nature, the biomass of large predators in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.根据他们发表在《自然》杂志上的论文显示，在开发了15年的渔场中，大型捕食动物的生物量平均减少了80%。在一些捕捞时间更长的区域，生物量再此基础上会再次减半。由此推出，有些地方的生物量是减少了90%。所以答案选择[A] the stock of large predators in some old fisheries has reduced by 90%在一些老的渔场，大型捕食动物的存量已经减少了90%。
对于比较难的题目，希望同学们仔细理解原文的含义。再次强调：题目的类型，定位方法，解题思路及选项特点分析清楚。做题时一定要严格的按照定位的原则，找到问题的出处，再根据定位句核心信息匹配正确选项。通过这种方式的训练，相信同学们会对解题过程把握的更加清楚。
