如果这类名词前用了a pair of等，则往往用作单数，谓语动词的单复数形式往往取决于pair的单复数形式。例如： Here are some new pairs of shoes. My new pair of socks is on the bed. 2. 意义一致的原则 （1）表时间、距离、价格、度量衡等的名词作主语时，谓语动词通常用单数。例如： Twenty years is not a long time. Ten dollars is too dear. （2）有些集合名词，如family, team等作主语时，如作为一个整体看待，谓语动词用单数；如指其中每个成员，则用复数。例如： My family is big one. My family are watching TV. （3）不定代词由all, most, more, some, any, none作主语时，也要依这些代词表示的意义来决定谓语动词的单复数形式。如果代词代表复数可数名词，谓语动词用复数；如果代词代表单数可数名词或不可数名词，谓语动词用单数。例如： All of the work has been finished. All of the people have gone. （4）疑问代词作主语时，其谓语动词也有两种情况：主语表示复数意义，谓语动词用复数；主语表示单数意义，则谓语动词用单数。例如： Who is your brother? Who are League members? （5）“分数或百分数+of+名词”构成的词组作主语时，其谓语动词要以of后面的名词而定。名词是复数，谓语动词用复数：名词是单数，谓语动词用单数。例如： It is said that 35 per cent of the doctors are women. Three -fourths of the surface of the earth is sea. （6）half, the rest等表示不定数量的名词作主语时，如果所指为复数意义，动词用复数；如果所指为单数意义，动词用单数。例如： I have read a large part of the book, the rest is more difficult. Only ten students attended the class because all the rest were off sick. （7）由what 引导地主于从句作主语时，通常谓语动词用单数形式。但如果所指内容为复数意义时，谓语动词用复数形式。例如： What she said is correct. What she left me are a few old books. （8）凡是以“定冠词+形容词（或分词）”作主语，往往根据意义一致的原则决定谓语动词的单复数形式。如果这种主语指的是一类人，谓语动词用复数；如果指的是一个人或抽象概念，谓语动词用单数形式。例如： The sick have been cured and the lost have been found. The dead is a famous person. 3. 邻近一致的原则 （1）由连词or, either……or, neither……nor, not only…but also,等连接的并列主语，如果一个是单数，一个是复数，则谓语动词按就近一致原则，与最靠近它的主语一致。例如： Either you or I am right. Neither the children nor the teacher knows anything about it. （2）在“There be” 句型中，谓语动词和靠近的主语一致。 There are two apples and one egg in it. （3）as well as 和名词连用时，谓语动词和第一个名词相一致。 He as well as I is responsible for it. 不但是我，他对这件事也有责任。 （4）以here开头的句子，其谓语动词和靠近的主语一致。 Here is a letter and some books for you.
