You might be checking out this Culips episode because you are brushing up on your English! In this episode we look at three expressions that mean exactly the same thing: to brush up on, to bone up on, to polish up on. These expressions are good to know if you are studying something you already know or refreshing 1 some of your old skills.
adj.使精神振作的，使人清爽的，使人喜欢的
- I find it'so refreshing to work with young people in this department.我发现和这一部门的青年一起工作令人精神振奋。
- The water was cold and wonderfully refreshing.水很涼，特别解乏提神。
