As I reflect on this significant event, a smile spreads across my face. As I think of Shanda, I feel loved and grateful.It was my twelfth year of dancing. I thought it would end up like any other year: stuck in emptiness, forgotten and without the belief of any teacher or friend that I really had the potential to achieve greatness.However, I met Shanda, a young, talented choreographer (编舞者). She influenced me to work to the best of my ability, pushed me to keep going when I wanted to give up, encouraged me and showed me the real importance of dancing. Throughout our hard work, not only did my ability to dance grow, but my friendship with Shanda grew as well.With the end of the year came our show time. As I went backstage, I hoped for a good performance that would prove my improvement. I waited anxiously for my turn. Finally, after what seemed like days, the loudspeaker announced my name. Butterflies filled my stomach as I took trembling steps onto the big lighted stage. But, with the determination to succeed and eagerness to live up to Shanda's expectations forme, I began to dance. All my troubles and nerves went away as I danced my whole heart out.As I walked up to the judge to receive my shining, gold trophy (奖杯), I realized that dance is not about becoming the best. It was about loving dance for dance itself, a getaway from all my problems in the world. Shanda showed me that you could let everything go and just dance what you feel at that moment. After all the doubts that people had in me, I believed in myself and did not care what others thought. Thanks to Shanda, dance became more than a love of mine, but a passion.4.What did the author think her dancing would be for the twelfth year?A.A change for the better.B.A disappointment as before.C.Proof of her potential.D.Pride of her teachers and friends.5.How did Shanda help the author?A.By offering her financial help.B.By entering her in a competition.C.By coaching her for longer hours.D.By awakening her passion for dancing.6.How did the author feel when she stepped on the stage?A.Proud.

甲:【24×2-24÷(1-15 )】÷(1-13 )=27(千克)乙:24×2-27=21(千克) 答:甲桶原有油27千克,乙桶原有油21千克。
