当proportion作“部分”解时,如a (the) proportion of N 作主语,其谓语动词的数取决于名词的数：
The greater proportion of the land is still uncultivated.大部分土地还未耕种.
A large proportion of my time is spent in studying.我的大部分时间都用在学习上.
A large proportion of students are workers and peasants.大部分学生是工人和农民.
当proportion作“比率；之比”解时,其谓语动词用单数.例如：
The proportion of women in the total work-force has risen.妇女在整个劳动力中所占的比率已经提高.
The proportion of men to women in the population has changed so that there are now fewer women and more men.人口中的男女比例改变了,现在是女的少,男的多.
The proportion of boys to girls in our class is three to one.我们班上的男、女生比例是3：1.

a large proportion of后的谓语动词应该用单数还是复数?由名词决定还是由proportion决定? a large quantity of ,large quantities of后面加n．的复数还是单数? a large quantity of 后接名词的复数形式,谓语动词应用单数还是复数 a pair of后加名词复数还是单数? a number of后加可数名词复数还是单数 a large sum of money是单数还是复数.为什么量词不用加S. a large sum of money后谓语动词用单数还是复数 neither of后加单数还是复数 large crowds后面加单数还是复数 a large quantity of +N.跟动词单数还是复数?还有large quantities of呢? a large number of和 large numbers of 后面的谓语动词用单数还是复数请问用a couple of加可数名词复数,动词用单数还是复数?
