一道英语冠词题
Some people think that __ air pollution may bring about changes in __ weather around the world.第一空不填,第二空填the,为什么?

一道英语冠词题Some people think that __ air pollution may bring about changes in __ weather around the world.第一空不填,第二空填the,为什么?
Air pollution 是 抽象名词, 在多数情况下,这种名词都用于单数形式,并不加任何冠词,
但有时也可加不定冠词a或an,使抽象名词具体化,或者加定冠词the 表特指
这里是泛指,所以不加冠词
weather 这里是特指全球的气候,根据the weather around the world 可知.名词有后置定语时,其前多用the 以表示特指某人或某物

air pollution,是泛指,或普通定义,不能用、也不用冠词来修饰。
但如果强调某一地区,就要加the,如
the air pollution in XX city
weather作天气讲时,永远在前面加the,
不要问为什么。

air pollution 没有特指哪里的,是泛指
weather around the world 是特指around the world的weather
