选项
A、Nitrogen Pollution.
B、Ecological Issues.
C、Goodbye, Skylarks.
D、Agricultural Advances.
答案
C
解析
本题是主旨题。本文首段通过对比,描述了几十年前云雀高歌的景象和现在不见踪影的凄凉,引出生态改变导致物种灭绝的问题。接下来的段落介绍了科学家们的调查结果,分析原因,指出人们的无知造成了物种灭绝。四个选项中,[A]“氮污染”是第四段提到的一个原因;[B]范围过大;[D]也是第四段提到的原因,排除。[C]虽然有些抽象,但文章以云雀的消亡入手,引出物种灭绝问题,因此[C]是各选项中最恰当的题目,故为答案。
