    Elvis Presley,who was one of the most popular American singers of the twentieth century, made the Rock & Roll music popular around the world. He sold millions of records and made many successful films, and he helped change the direction of popular music in the 1960s.

Elvis Presley was born in a poor family in 1935. His parents were simple country people who often took him to church, where he learned to sing and he never forgot the kind of songs that he used to sing in church as a child.

    When he was a teenager, Elvis moved from Tupelos to Memphis in Tennessee, where he attended high school, but he was not a good student. His only real interest was singing. He began to sing in the style that is called “country and western”.

    In 1955 he recorded some songs for his mother's birthday. The people at the recording studio liked his singing and his music. There was something different about it. It was country and western music, but it also sounded a little like the music, which black people used to sing in the American South, music kn own as “blues”.

   Shortly after that, Elvis met Tom Parker, who became his manager and arranged(安排)concerts for him across the United States and new recordings as well. Soon Elvis rose to fame all over the country. Later, Elvis went to Hollywood and began to appear in films like Love Me Tender and King Creole.

    But Elvis found it hard to live with success, like many other entertainment personalities (娱乐圈内的人士). He began to take drugs and his health began to suffer. When he died at an early age of 42 in 1977, his many millions of fans were shocked. “The King Is Dead!” the newspaper said. But today his memory and his music live on and he will always be remembered as the King of Rock & Roll.

阅读下列材料,并按要求回答问题。

材料一面对资源约束趋紧、环境污染严重、生态系统退化的严峻形势,必须树立尊重自然、顺应自然、保护自然的生态文明理念,把生态文明建设放在突出地位,融入经济建设、政治建设、文化建设、社会建设各方面和全过程。落实《巴黎协定》应顺应绿色经济、可持续发展的世界潮流,这充分尊重了经济社会发展的规律。当前,世界各国在经济全球化的大背景下,经济联系日益密切。气候变化作为一项全球性威胁,关系到世界各国的切实利益。自1992年《联合国气候变化框架公约》通过之后,国际社会就开始了合作应对气候变化的进程。治理好大气污染必须坚持在保护中发展、在发展中保护,实现环境效益、经济效益和社会效益多赢。按照全面推进与重点突破相配合的原则,实施分区域、分阶段治理。近年来,中国在发展的进程中高度重视气候变化问题,从中国人民和人类长远发展的根本利益出发,为应对气候变化做出了不懈努力和积极贡献。

材料二  近年来,随着全球现代化趋势的进一步发展,伴随着更大范围的环境污染和生态破坏,出现了历史上第二次世界范围的环境保护浪潮。这说明市场调节具有自发性等缺陷,要加强宏观调控。国家支持环境保护科学技术的研究、开发和应用,引导企业生产低碳环保产品,运用经济、法律和行政手段,鼓励企业减少污染,依法规范和惩处排放不达标企业,加大对企业的监督和检查,推动生态文明建设,建设美丽中国。中国计划于2017年启动全国碳排放交易体系,并把应对气候变化的行动列入“十三五”发展规划中。这是落实科学发展观的要求。中国支持巴黎气候变化大会达成一份全面、均衡、有力度的协议,主张协议应以《联合国气候变化框架公约》及其《京都议定书》为基础。
