sum、number、amount、quantity表示数量多少时的用法及区别? 答：a large quantity of 可以修饰可数名词和不可数名词.在…a large quantity of…后既可接复数可数名词,亦可接不可数名词.在它们分别和其后的名词构成短语作主语时,其谓语动词通常跟of 后名词的具体情况而采用单数或复数形式. a large sum of 通常是用来修饰不可数名词可数名词a large/ great/ good number of,通常是修饰可数名词. a large amount of指很多（很大数量）可以修饰可数名词也不可数名词.A large amount of students are playing games together.
