阅读中一道词汇题:
原文:The work of cognitive psychologists has illuminated the sutle forms of daily learning on which interllectual progress depends.
问题:The word "illuminated" is closest in meaning to ____
A)illustrated
B)accepted
C)clarified
D)lighted
答案是C),但A)为什么不对呢?在韦氏词典上illustrate就是用clarify解释的啊?
请大家帮帮忙!谢谢!
