thousand/million”;表示“成百、数千、上百万”等不确切的数字时,则用hun-

dreds/thousands/millionsof表达。如:Therearetwohundredpeopleinthehall.大厅里有200个人。Therearehundredsofpeopleinthehall.大厅里有数以百计的人。(2)表示“不确切岁数或年代”用几十的复数形式,结构为“in+one's+整十的复数”,“in+the+年代-s”。如:Hebecameaprofessorinhisforties.他四十多岁时成了一名教授。Itwasinthe1960s.那是在20世纪60年代。(3)表示顺序。由“单数名词+基数词”构成,此时名词和基数词的第一个字母
