Three-fifths of the workers here are women. 和这种情况类似的还有“a number of + 名词复数”。但是,“the number of + 名词”的中心词却是number。试比较： A number of students have gone to the countryside to help with the autumn harvest.

The departed (死者) was a well-known engineer. 这类形容词或分词如果要表示个体时,就要与名词man, person或表示人的单数连用。例如: an old man, a rich person, the (a) wounded soldier. 1.
