不可数名词也可以表示数，但须在其前面加上一个单位词（unit noun）：如number，amount，quantity，piece，sum，pair等。

如：

The amount of evidence against Jaime (不利于Jaime的证据) is great.
The quantity of books in the libraryis amazing(多得惊人).
The quantity of heat in the officehas not (been) increased.
例：Duringthe past year the ____ of automobile accidents in New York Cityhas decreased.
A. degree B. quantity C. number D. amount
【分析】介词 of 后面跟复数可数名词 accidents ，故应选 C。quantity 后面虽也可接复数可数名词，但句意的要求是数，而不是量，因此不能选 B。
A large____of older-model cars do not have proper smog-control devices.
A. amount B. lot
C. many D. number
