Shane Thomas is a 10-year-old pianist from England. He’s being called the next Mozart because of his amazing abilities.

He has only been having piano lessons for four months, and practices four hours a week, but he has already played difficult classical pieces. He was just seven when he sat down at the piano, and could play at once. He also says he never gets nervous.

When Shane was three years old, he said that he could play the piano, but nobody took him seriously. At school, he could listen to the teacher and do his work while composing (作曲) in his head. Shame remembers all the melodies(旋律),and when he gets home he plays them on the piano, while his father records them. Shane loves playing the piano, and when he grows up he wants to be a composer.

His tutor, Richard Goffin-Lecar, says he is like Amadeus Mozart, who lived during the 18th century in Salzburg, Austria, and was one of the most famous composers ever. Mr. Goffin-lecar says, “I don’t teach Shane very much. I just give him directions, then sit back and watch.”

His father, a single parent with two other children, says that although he has little money, he wants to send Shane to a good music school. “I’m a single father, but I have this gifted child. I don’t have much money, but I want to give him the best teachers, and also take him into a studio to record.”

56. When did Shane tell others that he could play the piano?

A. He feels nervous while playing the piano    

B. He can compose in his head while doing his work.       

C. He wants to be a piano tutor when he grows up.        

D. He doesn’t like to listen to the teacher at school.

58. What do we learn about Shane’s father?

②晶莹美丽的珍珠,其中心不过是颗砂粒,正所谓“病蚌成珠”。精美洁白的雪花,它的凝结中心或许就是一粒灰尘。疯狂施虐的台风,其中心竟然是一孔无风无雨,晴朗安宁的“风眼”。

③高尚的科学若溯本求源,其萌发中心也多为蒙昧异类。医学源于“巫术”;化学起于“炼丹”;天文学源于“占星术”;地理学源于“风水”;数学起于“数术”;概率论源发于“赌博”。就连科学的许多根本问题也都源自于宗教的原始追问,如生命起源、人类起源、宇宙起源、智能起源。

④大气中的水汽之所以能凝成雨滴,全靠空气中的尘埃作为凝聚中心。倘若天空绝对干净,哪怕大气中的水汽再多也绝不会下雨。可见,天空里若缺了这些“脏东西”,陆地上就没有雨,没有河流,没有植物,没有动物,当然更不可能有我们人类。一句话,没有灰尘我们就不能活!

⑤有时能成为“中心”的还非得异类。同类之物彼此相差无几,谁也难成谁的中心。异类的介入打破了这种无差异的均衡,“中心”自然也就应运而生。想当年梁山好汉一百单八将,各怀绝技谁肯服谁?倒是位武不如诸将,文不如军师的“异类”人物——宋公明,凭着“急公好义”的道德威望成了山寨的最高首领。
