[正] What is the population of Canada?
注:“人口”的英文 population 是不加“s”而構成復數(shù)的,所以不能用 many,但有時可以加不定冠詞,如 India has a very large population for its area.(印度以面積來說人口是很多的。)這個 population 當然也作單數(shù)用,如 Population sinks.(人中降低。)通常用作集合名詞,不加“s”構成復數(shù),除非是下列情形:the educated pupulations of China and Japan(中日兩國的知識階層)。
