文档介绍：一致原则
一致原则贯穿英语语法，在前面各个章节中已有涉及， 本章作为对前面的补充，集中讲、TOEFL题中常考的问题
第一节主谓一致
除了时态的变化外，名词、动词的数也有差别，这就要求主 语（以名词为代表）和谓语（包括助动词）在数上要一致如：
在名词+of+名词这种结构中，前一个名词是整个短 语的中心词，当该短语作主语时，一般以of之前名词的数为 of之后需接复数名词，但one of+名 词作主语时中心词是one,故谓语应用单数One of my students wins the game.
由and连接的多个名词作主语，谓语动词应用复数
Career and love are important to me.
im, John and Mary are playing football.
但是如果用and连接起来表示单一的概念时，谓语动词 要用单数
The famous singer and actress, Whitney Huston is coming to the ceremony.
（在这里，singer和actress指得是同一人，都是Whitney Huston）
不可数名词，尤其是抽象名词（relation, authority, necessity, power, democr acy, young 等）作主语时要视为单 数，谓语自然也要用单数
The relation between us is very simple.
单个从句作主语时，谓语用单数
That she has gone insane is sheer rumor.
When they will come hasn't been made public.
如果主语是单数，那么即使后面有
with/ together with/ alongwith/accompaniedby, no less than, like, but, except, including, besides
等引导的短语，谓语动词仍然要是用单数
例如：The boy, together with his parents, goes to the cinema today.
No one except the two boys knows how to solve this problem.
由 Not A but B, Not only A but also B, either A or B, neither A nor B引导的主语，谓语通常和最邻近的主语相一 致
Either you or Mary hurts her.
Neither my wife nor I myself am able to persuade my daughter to change her mind.
Not you but he is tired of typing.
Not only the students but also the teacher is going to be blamed.
在there be句型、介词短语、副词为句首引起的倒装句 中，真正的主语通常在
