题干

材料:所谓“皮革水解蛋白粉”,是指利用皮革下脚料甚至动物毛发等物质,经水解而生成的一种粉状物.因其氨基酸或者说蛋白质含量较高,人们称之为“皮革水解蛋白粉”.严格来讲,“皮革水解蛋白粉”对人体健康并无伤害,与在家里熬制猪皮汤、猪蹄汤得到的“肉冻”成分相差不多.不过无毒害的前提是用的皮革必须未经糅制、染色等人工处理,否则,就会含有重铬酸钾和重铬酸钠等有毒物质.如果用这种经人工处理过的皮革等原料生产水解蛋白,重铬酸钾和重铬酸钠自然就被带入产品中,被人体吸收、积累,可导致人体中毒,使关节疏松肿大,甚至造成儿童死亡.

    “Now stretch(伸展) over your right leg!” my dance teacher yells over the music. “If it doesn't hurt, you're not trying hard enough. Hold that stretch for 30 seconds!" My dance teacher works hard to form us into the dancers we desire to be. In order for this to occur, we stretch hard a lot!

    Dancing is a real passion of many people, including me. I work hard to make myself better, and prove that I am good enough. Performing a dance routine is more than just a  performance. Dancers tell stories when they dance. It is a way for us to express our personal feelings. Just letting go and letting your body move with the music can create your emotions. Dance tells us things that our mind secretly hides.

    “Get up and do it again!  You need to keep your spirits up!” Even though I am completely worn out after my dances, I love to hear those words. It gives me a sense of relief knowing that I can again express my feelings out on the floor.

    “Practice makes perfect! Come on. We have a competition this weekend, and we need to work harder!” Competitions are the best possible example of fun. For a dancer, life cannot get better than competitions. The thrill of losing yourself onstage is a rush of energy rushing through your body! The feeling is unexplainable. As you sit there putting on your makeup, fixing your hair, and putting on your costume, the rush just gradually grows until it is ready to be released onstage.

    Finally the time comes to tell your story. Standing backstage waiting for your name to be called is one of the scariest moments. You are ready to show the world what you are capable of and what you have been perfecting for a while. Once your number is called, you walk out onstage. The applause at the end tells each dancer that their story has been received, and that the dance has been brought to life.
