问题 单项选择题

由于近期的干旱和高温,导致海湾盐度增加,引起了许多鱼的死亡。虾虽然可以适应高盐度,但盐度高也给养虾场带来了不幸。
以下哪项如果为真,能够提供解释以上现象的原因______

A.持续的干旱会使海湾的水位下降,这已经引起了有关机构的注意
B.幼虾吃的有机物在盐度高的环境下几乎难以存活
C.水温升高会使虾更快速繁殖
D.鱼多的海湾往往虾也多,虾少的海湾鱼也不多

答案

参考答案:B

解析:本题是解释型题目。题干给出了“虾虽然适应高盐度,但却给养虾场带来了不幸”似乎矛盾的现象,具体是什么原因造成的呢肯定还存在一个原因使虾在这样的环境虾难以生存,我们看选项,A选项是无关选项,排除掉。B选项是可以说明这个结论,应该是正确答案;C选项不仅不能解释,反而更矛盾了,所以排除掉;D选项也无关,所以排除掉。故选B。
