阅读材料,完成下列各题。

材料一

事实上,无论在宗教改革运动之前或之后,政府没收教会财产都没有使它与罗马天主教的关系破裂。……看来经济条件所起的决定作用比宗教信念和政治形势的作用要小。加尔文教不仅在城市,而且在诸如苏格兰、波兰和匈牙利等农业国也同样赢得了信徒。路德教在经济停滞的北德意志要比在经济繁荣的南德意志发展得更为顺利。而在法国,当许多封建领主和农民皈依新教时,巴黎和许多其他城市仍坚定地信仰天主教。

材料二

在保留他们称之为圣餐或最后的晚餐的天主教弥撒仪式方面,路德和加尔文都反对圣餐变体论,但路德坚持认为上帝不管怎样确实呈现在礼拜仪式适用的面包和酒上,加尔文及其信徒则更趋向于将之看作是一种虔诚行动,具有象征性或纪念性的特点。

两人都大量吸收了圣奥古斯丁的观点,认为从神的赏罚观点看来,人依靠自己的行动永远不能解救,人具有的感化只能来自上帝的自由行动。加尔文是一个严厉的人性批评家,他觉得获得感化的人相对来说寥寥无几。他们是上帝的选民,是虔诚的信徒,是一小部分不靠自己的功德而早就被选定会得到拯救的人。

加尔文教徒不承认教会从属于国家,不承认任何政府有权制定有关宗教的法律。

材料三

欧洲的上层阶级有一种共同的、国际性的文化,这种文化的主体是法国文化。但是,英国也颇为重要。一直以来,人们多少认为英国属于欧洲的边陲地区,现在英国向中心靠拢了。可以说,孟德斯鸠和伏尔泰为欧洲“发现”了英国。

阅读理解

    Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO( United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.

    Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.

    It's Jason Moran's job to help change that. As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.

    "Jazz seems like it's not really a part of the American appetite," Moran tells National Public Radio's reporter Neal Conan. "What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and write anymore. It's actually color, and it's actually digital."

    Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. "The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same," says Moran.

    Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, "just to kind of put it back in the mind that Waller is dance music as much as it is concert music," says Moran. "For me, it's the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context," says Moran, "so I want to continue those dialogues. Those are the things I want to foster."
