three principles:important rules
1)语法一致:由and 连接的并列成分指的是同一概念,兼具身份或匹配出现时谓语为单数。否则用复数。
2) 就近一致:由or,either...or,neither...nor,not only...but also 等连接的并列主语,谓语动词常和靠近的作主语的名词单复数上保持一致。
但注意:主语+with/along with /together with/including /but/except/like/among/as well as /no more than /besides/rather than +名词,谓语和主语在单复数上保持一致。
3) 意义一致:集体名词class,family,army,team,club,population,enemy,party,crowd,crew,audience,public,government,majority,group等作主语时,如强调整体,用单数;如指各个成员,则用复数。
