a number of，the number of 1．a number of(=some)，修饰复数名词，作定语。谓语用复数。如：A number of people are standing outside the office.办公室外面站着很多人。注意：谓语用单数形式的情况也时有见到。如：A number of books is missing from the library.图书馆里有一些书丢了。句中谓语用单数，可理解为把a number of books视为一个整体，指丢失的一批书。2．a number of 的复数形式是numbers of ，意为“很多”。如：Numbers of people came from all parts of the country to see the exhibition.许许多多的人从全国各地前来参观展览。3．the number of 中的number指“总数量”，与复数名词连用。如：The number of people there is at least over 500.那儿的人数至少超过500。该句主语是number，people作number的后置定语，因此谓语用单数is。
