in (large) quantities、in quantity都表示“in a large amount”的意思，即“大量地”意思。
in small quantities 小量地
a large/small quantity大/小量的
quantities of =a large quantity of 大量的
e:She always buys vegetables in quantity.
这组单词一个是表示质一个是表示量，很容易搞混。其实，记牢两个名词的形式就迎刃而解了。记忆时我们可以这么认为：表示数量的多一个字母(n)，并且表示质量的是“l”，而表示数量的还是多一点，是“t”。下面的词性变化，两者是一样的，只是要注意两者意思的变化。
【语法】quantity的谓语动词的数与quantity的数一致，而与所修饰的名词的数无关。
e:Quantities of food were on the table.
