问题 单项选择题

我国酸雨主要出现于长江以南,北方只有零星分布,这是因为北方常有沙尘天气,来自沙漠的沙尘和当地土壤都偏碱性。 由此可以推出( )。

A.长江以北地区酸性污染物排放较少

B.长江以南地区的土壤偏碱性的较少

C.沙尘天气可有效降低酸雨出现的几率

D.有酸雨的地区出现沙尘天气的几率较小

答案

参考答案:C

解析: 本题属于直接推导型。题干陈述了一个因果关系:因为北方常有沙尘天气,中和了酸雨的酸性,所以,酸雨在北方只有零星分布。A、B两项明显错误。先排除;D项容易误选,D项倒置了酸雨和沙尘天气之间的因果关系,也排除;题干可以推出的是:沙尘天气可有效降低酸雨出现的几率。故选C。
