阅读下面的文言文，完成小题。
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。

    2, high school was different. In the first week, Jenna went to tryouts (选拔赛) for cheerleaders (拉拉队队员). She was competing against very talented girls, and she knew it would be 3 for her to be selected. Two hours later, the 4 read a list of the girls for a second tryout. Her heart 5 as the list ended without her name. Feeling 6, she walked home carrying her schoolbag full of homework.

    Arriving home, she started with math. She had always been a good math student, but now she was 7. She moved on to English and history, and was 8 to find that she didn't have any trouble with those subjects. Feeling better, she decided not to 9 math for the time being.

    The next day Jenna went to see Mrs. Biden about being on the school 10. Mrs. Biden wasn't as 11 as Jenna. “I'm sorry, but we have enough 12 for the newspaper already. Come back next year and we'll talk then.” Jenna smiled 13 and left. “Why is high school so 14?” she sighed.

    Later in 15 class, Jenna devoted herself to figuring out the problems that had given her so much 16. By the end of class, she understood how to get them right. As she gathered her books, Jenna decided she'd continue to try to 17 her new school. She wasn't sure if she'd succeed, but she knew she had to 18. High school was just as her mom had said: “You will feel like a small fish in a big pond 19 a big fish in a small pond. The challenge is to become the 20 fish you can be.”
