Shortly after the accident, two___________ police were sent to the spot to keep order.
A．dozens of
B．dozens
C．dozen of
D．dozen
答案：D
英语中一些表示数字的名词的前面如果用了数词，这些名词必须是单数形式，如dozen（一打），score（二十）和head（头）等，例如：另外两打鸡蛋another two dozen eggs。但是如果这些名词用来虚指某些可数名词时，这些名词呈复数形式，其后要加上介词of，例如：dozens of pencils（几十支铅笔）。

| One of the most well-known directors of our time is Stephen Spielberg. He was born in Cincinnati on 18 December 1946. His father was an electric engineer and his mother was a performing pianist. His sister, Anne Spielberg, became a screenwriter who wrote the stories for many famous films. Stephen had always wanted to be a director ever since he was a young boy. When he was just 13 years old, he made a 40-minute film. It won a local competition. Three years later, he produced a film called Firelight, which made one hundred dollars' profit at the cinema in his hometown. Many of the ideas from this film were later used for one of his most famous films called Close Encounters of the Third Kind. When he was 18 years old, he wanted to go to film school so that he could improve his skills and become an even better director. Unluckily, he was unsuccessful in getting a place at this school so he went to a university in California to study English. Even though he had failed to get into the school he wanted to go to, he didn't let this stop him following his dream to become a great director. Stephen Spielberg has directed many films since his first major film in 1976. He now owns many different businesses, most of which are involved in the film industry. | ||||||||||||
