求教英语大神,这句话语法错误在哪里?要怎么改?
As
an old saying goes,"Genius is nothing but labor and diligence." when we have
been learning in high school,it is necessary to seek different ways to improve
our academic performance.

这里不必用 现在完成进行时,否则不自然,因为句子说的是普遍道理.就算要加也要配合FOR +时间段语句,直接说 when we study in high school 就行了 而且 learn 一般是要接宾语的 study 可有可无
