材料一：世界近代史上，欧洲是国际关系错综复杂的热点地区之一，半个世纪以来，欧洲人为了实现“统一的欧洲”，一直进行着不懈的努力。从欧洲煤钢共同体到欧洲联盟，从20世纪50年代的6国到2004年5月的25国，从最初仅局限于经济合作到目前的政治、经济、军事一体化，“大欧洲”的宏伟蓝图正在一步一步成为现实。

材料二：严格意义上的经济全球化发生在20世纪80年代末90年代初-----全球化之所以发生在这个时期，第一靠全球的信息网络化，第二靠全球向市场化的变革。前者为全球化提供了技术上的保障，后者为全球化提供了体制上的保障。

    To me, music is food and water. I can't live without it. I know this is not true for everybody. Usually lots of people go to concerts or listen to music records. Maybe some of you don't do these and you get along quite well, but music is everywhere in our life. For example, when you see movies or watch TV plays, will you find them interesting if there is no music? I'm sure you will find them boring. And when you are waiting for the train or the plane, you would like some music because it makes the time seem shorter.

    Some people like to sit by the sea and listen to the sound of the sea. Some enjoy listening to the singing of birds. Those sounds are some kind of music. So music has a meaning for everyone to some extent. （程度） Of course, it has special meaning for people like me. We spend our lives playing or writing music.

    Someone said," Through music a child goes into a world of beauty, learn to take care of others and makes his mind and body healthy." Music is really an important part of our life.
