三个基本原则
1.语法上一致
主语为单数形式, 谓语动词用单数形式;
主语为复数形式, 谓语动词用复数形式。
(1) 主语形式虽为单数, 但意义为复数, 谓语动词用复数。
单数形式表示复数意义的词有people, police等。
2.意义上一致
(2) 主语形式为复数而意义上却是单数或不可数, 谓语动词用单数。
形复意单的词有: news, maths, physics等。
3.就近原则
谓语动词的单、复数取决于最靠近它的主语, 如there be句型或用连词either...or...,neither...nor..., not only...but also等。
1.There _____ a pen and some books on the desk. ( is / are )
is
2. There ____ any milk in the bottle. ★
isn't
3. Not only you but also he ____ late for yesterday's class meeting.
( was / were )
was
4. Either the teacher or his students ____ going to stay here.
(is / are )
are
5. Neither you nor I ____ wrong .
(am / is / are )
am
( 1 )class, family, team, school等集合名词作主语时,如果指整体,用单数;如果指每个成员,用复数。

( 3 ) trousers, shoes, glasses, socks, stockings, scissors
单独作主语时谓语动词 用复数。
(4 )当kind of, pair of, glass of等表示确定数量的名词短语修饰主语时,谓语动词应与kind,pair,glass等形式一致。
1. This pair of shoes __ dirty.( is / are )
is
2. There ____ two glasses of water on the table. ( is / are ) ★
3. Tom's new trousers ______ (be) blue.
are

4. The pair of glasses ______ ( fit / fits ) you well. ★

is
