初中英语语法之主谓一致讲解
考点名称：主谓一致 主谓一致的概念：
谓语的数必须和主语的人称和数保持一致，这就叫主谓一致。
主谓一致的基本原则：
1)语法一致原则，即在语法形式上取得一致。例如，主语是单数形式，谓语动词也采取单数形式；主语是复数形式，谓语动词也采取复数形式。
例如：The students are very young. This picture looks beautiful.
2)意义一致原则，即从意义着眼处理一致关系。例如，主语形式虽是单数但意义是复数，谓语动词也采取复数形式； 而有些主语形式虽是复数但意义上看作单数，谓语动词也采取单数形式。
例如：The people in that country are fighting for independence.
The crowd deeply respect their leader. Three years in a strange land seems a long time.
3)就近原则，即谓语动词的单数或复数形式取决于最靠近它的词语。
例如：Neither hen or I am going to see the film tonight
because we are busy.
几对容易混淆词组的一致用法：
1、由“this／thatkind／typeof+名词”作主语，谓语动词用单数形式；而由these／thosekind／typeof+复数名词”作主语，谓语动词用复数形式。
例如：This kind of apples is highly priced. Those kind(s) of tests are good.
2、由“a number of，a totalo f，an average of+复数名词”作主语，谓语动词用复数形式；由“the number of，the total of，the average of+复数名词”作主语，谓语动词用单数形式。 例如：A number of students are waiting for the bus. The number of the students in this university is increasing yearly.
3、one of，the(only) one of的一致用法
例如：This is one of the books that have been recommended. This is the(only) one of the books that has been recommended.
主谓一致用法点拨：
1、并列结构作主语谓语用复数： 如：Reading and writing are very important.
注意：当主语由and连结时，如果它表示一个单一的概念，即指同一人或同一物时，谓语动词用单数，and此时连接的
两个词前只有一个冠词。
如：The iron and steel industry is very important to our life. 典型例题：
The League secretary and monitor___asked to make a speech at the meeting. A. is B. was C. are D. were 答案：B.
注：先从时态上考虑。这是过去发生的事情应用过去时，先排除A、C本题易误选D，因为The League secretary and monitor 好象是两个人，但仔细辨别，monitor前没有the，在英语中，当一人兼数职时只在第一个职务前加定冠词。后面的职务用and相连。这样本题主语为一个人，所以应选B。 2、主谓一致中的靠近原则：
1）当there be句型的主语是一系列事物时，谓语应与最邻近的主语保持一致。
例如：There is a pen, a knife and several books on the desk. There are twenty boy-students and twenty-three girl-students in the class.
2）当either…or…与neither…nor，连接两个主语时，谓
