15.5 指代意義決定謂語的單復(fù)數(shù)
?
1） 在代詞what, which, who, none, some, any, more, most, all等詞的單復(fù)數(shù)由其指代的詞的單復(fù)數(shù)決定。
　　 All is right.　　　 (一切順利。)
　　 All are present.　　(所有人都到齊了。)

2） 集體名詞作主語時，謂語的數(shù)要根據(jù)主語的意思來決定。如family, audience, crew, crowd, class, company, committee等詞后用復(fù)數(shù)形式時，意為這個集體中的各個成員，用單數(shù)時表示該個集體。
　　 His family isn't very large.　　他家不是一個大家庭。
　　 His family are music lovers.　他的家人都是音樂愛好者。
　 但集合名詞people, police, cattle, poultry等在任何情況下都用復(fù)數(shù)形式。
　　Are there any police around?

3）有些名詞，如variety, number, population, proportion, majority 等有時看作單數(shù)，有時看作復(fù)數(shù)。
　A number of +名詞復(fù)數(shù)+復(fù)數(shù)動詞。
　The number of +名詞復(fù)數(shù)+單數(shù)動詞。
　A number of books have lent out.
　The majority of the students like English.
