  1.and连接的二个名词作主语时,主语与谓语动词的一致
  一般情况下,and连接的两个名词作主语时,谓语动词用复数形式。但有些情况下,and连接的两个名词意指同一人物、同一事物、同一概念时,谓语动词要用单数形式。通常,如果两个名词只有一个限定词或无限定词修饰时,它们常常表示一个概念,如果两个名词分别有两个限定词修饰时,它们往往表示两个不同的概念。另外,如果and连接的两个单数名词均有each, every, many a, no等词修饰时,谓语动词用单数形式。例如:
  War and peace is a constant theme in history.
  The wear and tear on the machine is obvious.
  The secretary and manager was present at the meeting.
  Every hour and every minute is vital to me now.
  Many a boy and many a girl has been to the exhibition.
  2.连词or等连续两个名词(或代词)作主语时,主语与谓语动词的一致
  连词or, either…or…, neither…nor…, not only…but also…连接两个名词或代词作主语时,谓语动词必须和靠它较近的一个名词或代词取得一致,这就是就近一致原则。例如:
  Either I or they are responsible for it.
  Neither your unkind words nor you unfriendly attitude has caused me any distress.
  Not only he but also his family members are interested in football match.
  3. none本身作主语时或它修饰的名词或代词作主语时,如代表不可数名词,谓语动词用单数形式,如代表可数名词,谓语动词既可用单数形式也可用复数形式。
  4.one and a half 后接的名词应是复数形式,但谓语动词用单数形式。如:
  One and a half years has passed.
  5. more than one 后接单数可数名词作主语时,谓语动词用单数形式,但如果more than one本身作主语,谓语动词则用复数形式。
  6.either, neither作主语时,谓语动词用单数形式。
  7.one or two后接复数名词作主语时,谓语动词用复数形式。
  8.one of后接复数名词作主语时,谓语动词用单数形式。
  9.动词不定式、动名词短语、名词性从句等作主语时,谓语动词用单数形式。例如:
  Seeing is believing.
  To hesitate means failure.
