15.The population of the world    over 6 billion in the 21st century.It became much _____ than that in the 20th.(  )
A.is;  biggerB.is;  largerC.are; greaterD.are;  more

分析 在二十一世纪,世界人口已超过六十亿.它比二十世纪的人口数量变得多了很多.

解答 答案:B.
population常与定冠词the连用,构成短语the population of.."…的人口";作主语用时,谓语动词常用第三人称单数形式;表示人口的"多"或"少",要用"large"或"small";根据The population of the world    over 6 billion in the 21st century.在21二十一世纪,世界人口已超过六十亿.中The population of the world做主语,那么谓语动词用单数is;在It became much _____ than that in the 20th.它比19世纪的人口数量变得更多了.中,表示人口的"多"或"少",要用"large"或"small";much来修饰比较级;故选B.

点评 在做题时先找准考点(the population of..…和比较级的修饰词),再结合语境和考点的用法(the population of…作主语用时,谓语动词常用第三人称单数形式.);做出正确的选择.
