Subject-VerbAgreement(主谓一致)
主谓一致指“人称”和“数”方面的一致关系。
1.语法一致原则
如果主语是单数，谓语动词则用单数形式；
如果主语是复数，谓语动词用复数形式。
eg.Bothparties______theirownadvantages.
Herjob_____somethingtodowithcomputers.
2.意义一致原则
有时，主语和谓语动词的一致关系取决于主语的单、复数意义，而不是语法上的单、复数形式，这样的一致关系就是意义一致。
Hisfamily______(be)abigfamily.
Hisfamily_______(be)listeningtomusic
whenhecameback.
ThepopulationinChina______(be)verylarge,andeightyofthepopulationinChina_____(be)farme rs.
3.就近原则
有时，谓语动词的单、复数形式决定于最靠近它的词语。
e.g.Eithermygrandsonsortheirfather__(be)coming.
NeitherRichardnorI_____(be)going.
