(13) :B白斑狗鱼是一种十分有害的鱼类。它体型很大，容易饥饿，以捕食其他小型鱼类为生。许多白斑狗鱼居住在戴维斯湖。它们捕杀那里的小型鱼类。白斑狗鱼对戴维斯湖造成了严重的威胁，因为它们捕食那里的所有小型鱼类。不久，湖中的所有其他鱼类都会被它们吃光。这对环境来说是不健康的。
研究人员担心白斑狗鱼会通过许多汇入戴维斯湖的小河游出戴维斯湖。这样它们就可能遍布整个国家，危害许多其他的水域。如果这种情况发生，到时再阻止白斑狗鱼就太晚了。
十年来，官员们试图将白斑狗鱼移出戴维斯湖。他们尝试用网捕捞和用毒药毒杀白斑狗鱼。但是，白斑狗鱼依然在戴维斯湖生活得很好。许多人不赞成用毒药毒杀白斑狗鱼。他们担心毒药对同样使用湖水的人类有害。但是，人们尚未在当地的井水中发现任何毒药的痕迹。
科学家打算再次尝试毒药。这一次，他们将会先抽干湖水，然后放入毒药。为了讨论这个问题，将会召开一次向公众开放的听证会。
推理题。题干意为“这篇文章的体裁可能是什么?”由文章叙述的口吻可知文章是从观察者的角度来客观陈述戴维斯湖面临的一个问题，由此可推断文章体裁最有可能是一篇新闻报道，故B为正确答案。
(14) :A细节题。题干意为“如果白斑狗鱼游出戴维斯湖将会发生什么?”由文章第二段可知，如果白斑狗鱼游出戴维斯湖将会遍布全国，给更多的水域造成危害，到那时再阻止它们就来不及了。由此可知，如果任由它们游出戴维斯湖，则会失去对它们的控制。故A为正确答案。
(15) :D细节题。题干意为“在戴维斯湖使用毒药的结果是什么?”由文章第三段第二、三句“They havetried using Nets and poisons.However，the Northern Pike population is still doingwell in Lake Davis.”可知，毒药对白斑狗鱼没有产生任何效果。故I)为正确答案。
(16) :A推理题。题干意为“将要召开向公众开放的听证会是因为什么?”由文章第三段可知，人们反对用毒药毒杀白斑狗鱼，因为害怕人们使用的井水受到污染。而第四段第一句话指出科学家打算再次尝试用毒药消灭白斑狗鱼，由此可以推出，召开听证会的原因是当地居民反对使用毒药，为此要征求大家的意见。故A为正确答案。
