The world’s elderly population will exceed(超过) ____ of children by 2060, when each group ____ to account for about one fifth of the population.

A.that ; is expected

B.it; will expect

C.that; expects

D.one ; will be expected

答案

答案:A

题目分析:句意:到2060年为止是,世界老年人口的数量将超过孩子们人口的数量,到那时,分别占到了整个人口的五分之一。that指代the population, be expected to 有望…,不定式形式表将来。

点评:that和it主要的区别在于It 常用来代替前文中所提到的同一个东西,属于同名同物,而that属于同名异物。The umbrella you bought is cheaper than that I bought. (替代词that在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”);而one 表泛指。
