overachieve

1.David continued to overachieve all through high school.

戴维在整个中学期间的成绩都预期的好。

2.I know from my own experience in France that with the end of your career looming, older players can sometimes overachieve, have a last hurrah and briefly roll back the years.

从我在法国时的经历来看，在球员职业生涯的末期，一些大龄球员有时往往能超水发挥，在职业的暮年作出最后的努力。
