一,动词单复数的特殊固定用法

the number of …的数量;其后的动词在任何情况下都用单数。
量词考点:a group/list/line of 使用“就前原则”
(2) 倒装结构:就后原则。
如:here comes the bus
a. 地点状语+动词+主语
b. Only置于句首的倒装
例:In the foothills of that large mountain range is (A) the sources of a river whose course (B) was not fully mapped (C) until (D) this century. No error (E). (P 776.19)
例:Air pollution caused by industrial fumes has been studied (A) for years, but (B) only recently has (C) the harmful effects of noise pollution become (D) known. No error (E). (P167.6)
二,名词单复数固定用法
集合名词:family, group, stuff, team, community,只要这些词以单数结尾,后面的谓语动词都用单数。
people, cattle, police :其后的谓语动词用复数
以s结尾的词:means, species, news
以cs结尾的词:physics, mathematics,不表示复数,是单数。
以us结尾的词:octopus(章鱼), platypus(鸭嘴兽), -saurus(恐龙)
