a number of 和a great deal of 在意思上相同,但用法不一样.a number of 后面只能跟可数名词的复数形式,而a great deal of 后面只能跟不可数名词.例如:A number of accidents always occur on rainy days.雨天常常有许多事故发生.A number of books are missing from the library.图书馆的一些书不见了.I spent a great deal of my time on this work.我在这项工作上花了不少时间.另外,a great deal of 也可说成a good deal of.例如:She spends a good deal of money on clothes every year.她每年在衣服上花了不少钱.除了a number of 之外,也可以用a large/good number of 或(large) numbers of 来表示数量众多,意思为“大量的,众多的” 例如:Numbers of people came from all parts of the country to see the exhibition.许多人从国内来参观这个展览.需要引起注意的是,若用the number of ,后面仍需用名词复数,但谓语动词则应用单数.因为这时表示的是数字,而非数量.例如:The number of books missing from the library is very large.图书馆遗失的图书数量很大.
