分析 文章大意：
没有人知道什么时候爵士乐被发明，或是由谁发明的．但据说，它开始于19世纪初．爵士对于美国和世界是一种新的音乐，新奥尔良是它的发源地．
谁是爵士乐先驱者？大多数是黑人．这些音乐没有写下来，最初只是黑人演奏它．白人音乐家很难学习新的风格．但很快，他们也演奏爵士乐．
这个音乐很快的流行开来，从新奥尔良到了密西西比，再到芝加哥，然后到堪萨斯城和纽约．在20世纪20年代，有许多爵士音乐家，白人也有，黑人也有．他们中的许多人都是非常有名的．其中有一个人比其他人都更受欢迎．他的名字是路易斯•阿姆斯特朗．
路易斯•阿姆斯特朗是一个音乐家．他不仅有才华，而且努力工作．他也有一个良好的幽默感和一个大而温暖的微笑．这些个人品质在他成名的路上是有很大价值的．他成为知名音乐家，他走遍了世界．似乎每个人都想听到路易斯的音乐．但生活并不总是容易的，特别是在开始．
路易斯•阿姆斯特朗出生于1900年的新奥尔良．父亲从来没有上过学，他的母亲几乎无法阅读．当路易斯还是一个小孩子时，他的父母离婚，路易与他的母亲住在一起．他们的生活是可以想象的．然而路易斯微笑面对一切．他后来写道："我的一生都是幸福的．生活就在我身边，我接受它．无论发生了什么，对我而言都是美丽的．我爱大家．"

79．C，推理判断题．根据短文最后一段"How hard their life was can readily be imagined．And yet Louis smiled through everything．"可知阿姆斯特朗小时候生活很艰辛，但是他仍旧笑对生活．故选项C最好的表达了他的生活态度．
80．D，主旨大意题．阅读短文可知前三段讲述了爵士乐的发展，后两段讲述了最好的爵士乐音乐家．故选D．
