      环滁皆山也。其西南诸峰，林壑尤美，望之蔚然而深秀者，琅琊也。山行六七里，渐闻水声潺潺而泻出于两峰之间者，酿泉也。峰回路转，有亭翼然临于泉上者，醉翁亭也。作亭者谁？山之僧智仙。名之者谁？太守自谓也。太守与客来饮于此，饮少辄醉，而年又最高，故自号曰醉翁也。醉翁之意不在酒，在乎山水之间也。山水之乐，得之心而寓之酒也。

      若夫日出而林霏开，云归而岩穴暝，晦明变化者，山间之朝暮也。野芳发而幽香，佳木秀而繁阴，风霜高洁，水落而石出者，山间之四时也。朝而往，暮而归，四时之景不同，而乐亦无穷也。

      至于负者歌于途，行者休于树，前者呼，后者应，伛偻提携，往来而不绝者，滁人游也。临溪而渔，溪深而鱼肥，酿泉为酒，泉香而酒洌，山肴野蔌，杂然而前陈者，太守宴也。宴酣之乐，非丝非竹，射者中，弈者胜，觥筹交错，起坐而喧哗者，众宾欢也。苍颜白发，颓然乎其间者，太守醉也。

      已而夕阳在山，人影散乱，太守归而宾客从也。树林阴翳，鸣声上下，游人去而禽鸟乐也。然而禽鸟知山林之乐，而不知人之乐；人知从太守游而乐，而不知太守之乐其乐也。醉能同其乐，醒能述以文者，太守也。太守谓谁？庐陵欧阳修也。

阅读下列短文，从每题所给的 A、B、C 和 D 四个选项中，选出最佳选项。
    A high school senior from Houston, Texas, was accepted by each of the 20 top-ranked universities to which he applied — and was offered a full scholarship to every single one of them.
    Michael Brown, a 17-year-old student at Lamar High School, went viral（迅速成名） after he was caught on camera screaming in glee upon learning he was accepted into Stanford University in December.
    Little did the teen know at the time, but his excitement would increase by a factor of 20 in March when he was also accepted into Harvard, Princeton, Yale, the University of Pennsylvania, Georgetown, Northwestern, Vanderbilt and the University of Michigan, among other prestigious（著名的） colleges.
    But what did it take for Brown to pull off his flawless（完美无瑕的） clean sweep?
    To start, the high schooler has an impressive 4.68 grade point average and an SAT score of 1540 out of 1600. His ACT score, a 34 out of a possible 36, proved to be just as excellent. Brown's extracurriculars also include various internships as well as participation on his high school's debate team.
    His mother, Berthinia Rutledge-Brown, told The New York Times that she was simply blown away by her son's perfect performance. "He actually earned it," she told the Times. “I always knew Mike would get into a good school. I always knew he'd get good scholarship support. But I never imagined this."
    So, which school will he be attending this fall? Although Brown remains undecided at the moment, he reportedly plans to major in political science and hopes to one day become a lawyer.
    He will make the big decision by May 1.
