今天我们来为大家讲解的是主谓一致的语法知识，通过这些知识点，可以帮助大家更好的来备考
1. 就前原则
(1) N1 of N2 verb(SAT考试中动词的单复数与N1有关，与N2无关)
如： a group of students are the details of the problems are
例：The bright (A) fiberglass sculptures of Luis Jimenez has received (B) critical acclaim not only (C) in his home state, New Mexico, but also in (D) New York.
No error (E). (P161.1)
(2) 名词1+介词+名词2 如：students in the classroom
名词，插入语，verb
名词+doing/done 如：students studying hard
例：Flints found in (A) the region extending from the Nile Valley to (B) the highlands of eastern Iraq attests to (C) the presence of people there as long ago as (D) one hundred thousand years. No error (E). (P166.3)
2.“欲擒故纵”法
动词单复数做题基本原则是就前原则，如果句子太长、太难、太复杂时，用“欲擒故纵”法。
3.动词单复数的特殊固定用法
(1) a number of 一些;一般情况下其后动词用复数，(不受任何规律限制);
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)
4.名词
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)
考点：名词的单复数
