As is known to all,having a good knowledge of vocabulary is______language learning.A. based onB. based to C. basic to D. basic on

熱心網友

選C.上面那位仁兄估計是看錯了句子的意思：眾所周知，擁有很好的詞匯知識是學習一門語言的基礎。“基礎”在前，所以用 A be basic to B. A是B的基礎。如果上面的句子反過來說：Language learning is based on a good knowledge of vocabulary。就用 A be based on B。A 形成（建立）于B基礎之上。大家以為呢？

熱心網友

肯定是A。based ...on固定搭配。
