总复习（320）

多比：

多比是一个为马尔福家族服务的家养小精灵。与其他家养小精灵不同，多比渴望自由，并厌恶主人特别是卢修斯·马尔福的残忍。他第一次出现是为了警告哈利·波特，如果他回到霍格沃茨上二年级，将会遇到危险。多比试图保护哈利，包括阻止他进入九又四分之三站台，以及在魁地奇比赛中施咒让游走球攻击哈利。尽管有时会对哈利造成伤害，但多比的意图是纯洁的，旨在保证哈利的安全。故事结尾，哈利通过给卢修斯·马尔福一只袜子，成功骗他释放了多比，使多比获得了自由。

吉德罗·洛哈特：

吉德罗·洛哈特是霍格沃茨新任黑魔法防御术老师。他是一位著名作家，以其所谓的英雄事迹和畅销书而闻名。然而，洛哈特比起真正的勇气或教学更关心名声和自我宣传。他的无能在学年中表现得淋漓尽致，尤其是在涉及康沃尔郡小精灵的灾难性课程中。洛哈特的真面目被揭露出来，原来他一直在通过抹去其他巫师的记忆来窃取他们的成就。他最后的懦弱行为是在试图逃离学校时，误用反弹咒语抹去了自己的记忆。

汤姆·里德尔：

汤姆·马沃罗·里德尔通过一本被施了魔法的日记首次亮相，后来被揭示为年轻的伏地魔的记忆。日记使里德尔能够控制金妮·韦斯莱，迫使她重新打开密室并释放蛇怪。作为五十年前霍格沃茨的学生，里德尔诬陷海格为袭击事件的罪魁祸首，并计划清除学校里的麻瓜出身的学生。通过日记，里德尔操纵事件以恢复自己的力量。最终，哈利摧毁了日记，消灭了里德尔的记忆，救了金妮，但这次遭遇强调了伏地魔持续存在的威胁。

Dobby:

Dobby is a house-elf who serves the Malfoy family. Unlike other house-elves, Dobby seeks freedom and detests the cruelty of his masters, particularly Lucius Malfoy. He first appears to warn Harry Potter about the dangers awaiting him at Hogwarts if he returns for his second year. Dobby’s attempts to protect Harry include blocking his access to Platform 9¾ and sabotaging a Quidditch match by enchanting a Bludger to attack Harry. Despite his sometimes harmful actions, Dobby’s intentions are pure, aiming to keep Harry safe. By the end of the book, Harry tricks Lucius Malfoy into freeing Dobby by presenting him with a sock, which marks Dobby’s emancipation.

Gilderoy Lockhart:

Gilderoy Lockhart is the new Defense Against the Dark Arts teacher at Hogwarts. He is a famous author known for his supposedly heroic exploits, detailed in his many best-selling books. However, Lockhart is more concerned with fame and self-promotion than genuine bravery or teaching. His incompetence is evident throughout the school year, particularly during a disastrous lesson involving Cornish Pixies. Lockhart's true nature is revealed when it is discovered that he has been taking credit for other wizards' achievements by erasing their memories. His final act of cowardice occurs when he attempts to flee the school but ends up accidentally erasing his own memory with a backfired spell.

Tom Riddle:

Tom Marvolo Riddle, initially introduced through an enchanted diary, is revealed to be the memory of a young Voldemort. The diary allows Riddle to possess Ginny Weasley, forcing her to reopen the Chamber of Secrets and unleash the basilisk. As a student at Hogwarts fifty years earlier, Riddle framed Hagrid for the attacks and aspired to rid the school of Muggle-borns. Through the diary, Riddle manipulates events to revive his power. Harry ultimately destroys the diary, vanquishing Riddle’s memory and saving Ginny, but the encounter underscores Voldemort’s enduring threat.
