The number of the people who own cars ______since 1990. A．is increased B．are increased C．have been increasing D．has been increasing

Answer 1

D

试题分析：考查主谓一致和时态；本题的主语是the number of…指…的数量。定语从句who own cars修饰the people。本句的主语是the number of…指…的数量；该短语做主语时，谓语动词用单数。根据since说明本句使用完成时。句意：自从1990以来拥有汽车的人的数量一直都在增加。故D正确。 点评：本题考查了number两个短语。The number of…做主语，谓语动词用单数；a number of做主语,谓语动词用复数形式。
