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：
My class is a big one, including thirty boys and thirty girls.
My class are working hard for the coming exam.
2. 有些集合名词作主语时,谓语只能用复数形式,如：people, the police, the military, mankind, cattle等.如：
The police are searching for the lost child.
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, no one, nobody, nothing, each, the other等作主语时,谓语动词用单数.如：
Everything goes well with me.
Each of the students in our class has an English-Chinese dictionary.
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：A novelist and playwright is coming to our school. 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A novelist and a playwright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：A novelist and a playwright are coming to our school.
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：The beautiful is the true.
当The ＋ adj.表示该类全体的含义时,谓语动词用复数.如：The rich should help the poor.
