热点语法

主谓一致用法难点小结:

一、集合名词作主语时的主谓一致。

1.集合名词有family,team,group,party,class,public,club,crew,crowd,enemy,audience,company,committee,government,population等,当被看作一个整体时,表示单数意义,谓语动词用单数形式;如果这些集合名词指其中的每个成员,表示复数意义,谓语动词则用复数形式。

即谓语动词的单复数要与主语的含义相一致。

如:

Myclassisabigone,includingthirtyboysandthirtygirls.Myclassareworkinghardforthecomingexam.

2.有些集合名词作主语时,谓语只能用复数形式,如:

people,thepolice,themilitary,mankind,cattle等。

如:

Thepolicearesearchingforthelostchild.二、不定代词作主语时的主谓一致。

不定代词anyone,anybody,anything,everyone,everybody,everything,someone,somebody,noone,nobody,nothing,each,theother等作主语时,谓语动词用单数。

如:

Everythinggoeswellwithme.

EachofthestudentsinourclasshasanEnglish-Chinesedictionary.三、“名词+名词”作主语时的主谓一致。

当表示同一人物或观点时,谓语动词用单数。

如:

Anovelistandplaywrightiscomingtoourschool.这里表示“一位小说家兼剧作家”,是同一个人,所以谓语动词用单数。

如果是Anovelistandaplaywright作主语,这时表示“一位小说家和一位剧作家”,是两个人,所以谓语动词用复数,该句应改为:

Anovelistandaplaywrightarecomingtoourschool.四、The+adj.作主语时的主谓一致。

当The+adj.表示抽象的含义时,谓语动词用单数。

如:

Thebeautifulisthetrue.当The+adj.表示该类全体的含义时,谓语动词用复数。

如:

Therichshouldhelpthepoor.必修4Unit2Workingtheland知识点讲解Unit2Workingtheland
