As the College Entrance Examination is drawing nearby, some students would rather expect

good luck than to make every effort to study．They think success results good luck．Whether they can be admitted to key universities depend on luck．However, others insist that diligence is a mother of success．Only by working hard can they achieve what they want．Since they fail sometimes, they don’t give up, for they believe that success lies in our own hands．As for me, I’m in favor of the latter opinion．Luck doesn’t come alone．It goes hand by hand with hard working．Sometimes, some students are lucky enough to succeed, but such luck won’t last long because it is not basing on their own abilities．
