請看以下內容
一,a number of 和a great deal of 在意思上相同,但用法不一樣.a number of 后面只能跟可數(shù)名詞的復數(shù)形式,而a great deal of 后面只能跟不可數(shù)名詞.
例如：A number of accidents always occur on rainy days.雨天常常有許多事故發(fā)生.
A number of books are missing from the library.圖書館的一些書不見了.
I spent a great deal of my time on this work.我在這項工作上花了不少時間.
另外,a great deal of 也可說成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錢.
二,你說的a large/good number of 或(large) numbers of 是表示數(shù)量眾多,意思為“大量的,眾多的”
例如：Numbers of people came from all parts of the country to see the exhibition.
許多人從國內來參觀這個展覽.
三,需要引起注意的是,若用the number of ,后面仍需用名詞復數(shù),但謂語動詞則應用單數(shù).因為這時表示的是數(shù)字,而非數(shù)量.
例如：The number of books missing from the library is very large.
圖書館遺失的圖書數(shù)量很大.
