熱點語法
主謂一致用法難點小結：
一、集合名詞作主語時的主謂一致。
1. 集合名詞有family, team, group, party, class, public, club, crew, crowd, enemy, audience, company, committee, government, population等，當被看作一個整體時，表示單數(shù)意義，謂語動詞用單數(shù)形式；如果這些集合名詞指其中的每個成員，表示復數(shù)意義，謂語動詞則用復數(shù)形式。即謂語動詞的單復數(shù)要與主語的含義相一致。如：
My class is a big one, including thirty boys and thirty girls.
My class are working hard for the coming exam.
2. 有些集合名詞作主語時，謂語只能用復數(shù)形式，如：people, the police, the military, mankind, cattle等。如：
The police are searching for the lost child.
二、不定代詞作主語時的主謂一致。
不定代詞anyone, anybody, anything, everyone, everybody, everything, someone, somebody, no one, nobody, nothing, each, the other等作主語時，謂語動詞用單數(shù)。如：
Everything goes well with me.
Each of the students in our class has an English-Chinese dictionary.
三、“名詞＋名詞”作主語時的主謂一致。
當表示同一人物或觀點時，謂語動詞用單數(shù)。如：A novelist and playwright is coming to our school. 這里表示“一位小說家兼劇作家”，是同一個人，所以謂語動詞用單數(shù)。
如果是A novelist and a playwright作主語，這時表示“一位小說家和一位劇作家”，是兩個人，所以謂語動詞用復數(shù)，該句應改為：A novelist and a playwright are coming to our school.
四、The ＋ adj.作主語時的主謂一致。
當The ＋ adj.表示抽象的含義時，謂語動詞用單數(shù)。如：The beautiful is the true.
當The ＋ adj.表示該類全體的含義時，謂語動詞用復數(shù)。如：The rich should help the poor.
