释义 | 1.Room Number 123, bus number 73 等表达方式里在 Room, bus 等词前面没有 the。 2.a number of (许多)后面必须接复数形式的名词或代词,动词有时用复数,有时用单数,如 A number of boys(或them)are(或is)in the next room 和 A large number of books are(或is)lent at the library every day。有人以为用单数形式的动词不算正当。 比较下面两句: An increasing number of pupils have made use of the library. An increasing number of pupils has made it necessary to keep more copies of the same books. 第一句着重在“更多的学生”,第二句着重在学生数的增加。 3.在公文里往往把 in a number of cases 用作 often 解。 |
