Perhaps　the　only　test　score　that　I　remember　is　the　55　when　I　was　in　high　school.

    The　test　was　the　final　for　a　course.　I　remember　waiting　anxiously　as　my　teacher　Mr.　Right　passed　out　our　papers　one　by　one.　It　was　a　rather　difficult　test.　I　heard　my　classmates　groaning,　and　I　could　tel　by　the　groans　that　the　scores　weren’t　looking　good.

    Mr.　Right　put　my　paper　on　my　desk.　There　in　big　red　numbers,　circled　to　draw　attention,　was　my　score,　55!

    I　lowered　my　head,　and　covered　the　score　up　quickly.　A　55　is　not　something　that　you　wanted　your　classmates　to　see.“The　scores　were　not　very　good,　none　of　you　passed,”Mr.　Right　said.　“The　highest　score　in　the　class　was　a　55.”

    A　frown（皱眉）now　stood　on　my　father’s　face.　I　knew　I　had　to　explain　immediately.　“But　Dad,　I　had　the　highest　score　in　the　calss,”I　proudly　stated.　I　thought　that　explanation　would　make　a　difference.“You　failed!”my　father　replied.“But　it’s　the　highest!” I　insisted.“I　don’t　care　what　scores　others　had,　but　you　failed.　What　matters　is　what　you　do!”my　father　firmly　said.

    For　years,　my　father　was　always　that　way.　It　didn’t　matter　what　others　did,　it　only　mattered　what　I　did　and　that　I　did　it　excelently.

    We　often　don’t　understand　the　wisdom（智慧）of　good　parents　until　we　ourselves　stand　in　the　parents’shoes.　My　father’s　words　have　carried　me　throughout　life.
