在英语的句子中，谓语动词的形式应与主语的人称和数保持一致。近几年来，高考关于该内容的考查主要集中在语法一致、逻辑意义一致以及就近（远）一致原则等三个方面。
一、语法一致原则
只要确定句子的主语是单数意义，则谓语用单数，句子的主语意义复数，则谓语用复数。具体表现如下：
1.不可数名词作主语，一律视为单数。某些以s结尾的单数名词作主语，仍视为单数。
No news is good news.
His task was to collect information.
How much machinery has been installed?
2.表示单一概念的动名词、不定式或句子作主语时，谓语动词用单数。
When and where to go for the on－salary holiday has not been decided yet.
3. “ one, either, neither, each of ＋复数名词或代词”作主语时， 谓语用单数。
Either of the stories is very funny.
4.something, everything, anything, nothing，somebody, nobody, no one 等不定代词作主语，谓语通常是单数。
Nothing is impossible.
5.表示时间、金钱、距离、重量、数量的复数名词作主语，通常看作一个整体，谓语动词用单数。
Ten pounds was missing from the box.
6. a series of, a kind of, a piece of, a pair of 等量词修饰名词，通常以量词的单复数形式来决定谓语的单复数。
