贵阳君临天下三期:dozen & score

一、dozen表示“ 打，十二个”的意思，而score表示“二十”的意思。二、两词与数词，a,many,several连用修饰名词复数时，都要用单数，其后的介词of有无均可。但是，习惯上score多与of连用，而dozen很少与of连用，如：two score(of)workers,three score and ten people,several dozen children,many dozen books。三、两词与of连用（of不省略）时，可用于人称代词宾格（us,you,them）或指示代词（these,those）修饰的名词前，表示所属关系。如：a dozen of these/those pelple,two dozen of them/us,a score of these/those workers.四、 两词的复数形式与of连用时，表示不确切的数量，意为“许多……，大量的……”。如：dozens of people,dozens of times,scores of people.而some dozen people是“一打左右的人”（大约十二人）与some dozen of people同义。（some）dozen of people是“若干打的人”（几十个人，许多人）。五、除了上述用法之外，还要注意下列习惯用语：（pack）in dozens〔成打（包装）〕，（sell）by the dozen[论打（出售）],in scores(成批的)练习：1.
