对,那是正确的。这与studying准确地说,它指的是回顾和重新训练以前学到的东西。示例: I need to brush up on my maths if I'm going to teach it to my son. (如果我想教我儿子数学,我需要再复习一遍。) 例子: Mary majored in history such a long time ago. She needed to brush up on it again. (玛丽很久以前学过历史。她需要重新学习。) 示例: I'm brushing up on my cooking skills tonight and making dinner! (今晚,我又要练练厨艺,做晚饭了!)
