( 十四 ) 主谓一致 英语中，主语的单复数形式决定着谓语动词的单复数形式。主谓一致必须遵循以下三条原则：语法一致原则、意义一致原则、就近一致原则。1. 并列结构作主语时。▲ 由 and 连接的两个单数名词作主语时，谓语动词用复数。如： A young man and a girl want to go there.★ 但如果在意义上指同一个人、同一件事或同一个概念时，谓语 动词要用单数形式。如： A needle and thread was found on the floor.▲ 当 each...and each... ； every...and every... ； no...and no... ； many a...and many a... 结构作主语时，谓语动词用单数形式。如： No man and no animal is to be found on the moon. Many a doctor and many a nurse is busy with their work.▲ 由 not only...but also... ； either...or... ； neither...nor... ； or 连接的 并列主语，谓语动词与就近的名词或代词保持一致。如： Either the players or the coach is responsible for the defeat.▲ 当主语由 as well as, along with, together with ， rather than, no less than, but, except, besides, in addition to, like, including 等词连 接时，其谓语动词与前面的名词或代词保持一致。如： An iron and steal works, with some satellite factories, is to be built here. Tom, along with his friends, goes skating every Saturday. 2. 百分数、分数作主语时。 当百分数、分数后面加名词或代词时，要根据这个名词或代词 来决定其谓语动词的单复数形式。如果是复数名词或代词，谓 语动词用复数；如果是单数名词 ( 或不可数名词 ) 或代词，谓语动 词用单数。如： Fifty percent of the students in our school are girls. Three fourths of the surface of the earth is sea.3. 不定代词作主语时。▲ 不定代词 each, another, the other, either, neither 和由 some, any, no, every ＋ one 或 thing 构成的复合代词作主语时，谓语动词用单 数形式。如： Neither of us has gone through regular training. Nobody wants to go there ， does he? Something has been done to end the strike.▲all 作主语表示人时，谓语动词用复...
