沒錯!此片語與「studying」意思相似,指的是溫習、複習以前學過的東西。 例:I need to brush up on my maths if I'm going to teach it to my son. (如果我想教我兒子學數學,我得先複習以前學過的內容。) 例:Mary majored in history such a long time ago. She needed to brush up on it again. (瑪麗以前主修歷史。她得先溫習過往所學得專業知識。) 例:I'm brushing up on my cooking skills tonight and making dinner! (我今晚需先練練我的廚藝,再來煮晚餐!)
