Many people agree that ( )knowledge of English
Many people agree that ( )knowledge of English is a must in( )international trade.A.a,/ B.the,an C.the,the D./,the 为什么?

第一空:a knowledge 指对英语的了解,此处抽象名词表示种类,前面应加不定冠词.a knowledge of 指的是比较广泛的某门学科的综合知识.而the knowledge of指的是比较具体的某种办法的知识,比如The Knowledge of Life(生活小常识),The Knowledge of Healing(疗愈的知识).英语知识应该是一个综合的知识,它可以包括英语会话和英语社交常识等等,所以用a.
第二空:international trade指国际贸易,表泛指,故不加冠词
