(1) This sheep is white这只羊是白色的。
(2) These sheep are black.这些羊是黑色的
上两句的sheep单复数的形式是一样的。 one sheep(一只羊), several sheep(几只羊)。而其谓语形式取决于该词在句中的用法。
类似这样的词有deer(鹿), fish(鱼), Fruit(水果)等。例如:
(3) A deer is easily frightened and can runvery fast.鹿很容易受惊,而且能跑得很快。
(4) The deer there like to eat a certain kindof wild rose.那里的鹿喜欢吃某一种的野玫瑰。
(5) He caught only one fish before lunch.他在午饭前只抓到一条鱼。
(6)There were hundreds of fish in the pond塘里有上千条鱼。
注:fish作“鱼”的统称,其单复数形式一样,但当表示不同种类的鱼(different kinds of fish)时,其复数形式为fishes.例如:
(7) I caught three large fish、我抓到了三条大鱼。
(8) Would you like some Fruit你要点水果吗?
注:fruit是“水果”的统称,不可数名词,只能与some,much,a plenty of等连用,因此没有复数形式,写成a fruit,many fruits是错的。但当表示各类水果(different kinds of fruit)时,有其复数形式fruits
例如:
(9)Apples snd oranges are fruits.苹果和橙是水果。
(10)What fruits are in season now?现在有哪些水果上市?
