作者以异乎寻常的想象力，描写主人公格列佛先后出游"小人国"、"大人国"、"慧因国"等地方时，遭遇的种种千奇百怪的事情。比如在"小人国"里他可以随意地把上至国王小到平民的各式人等摆在手掌心里玩弄；而在"大人国"里，他又能像个幼儿那样处处受制于人；到"慧因国"以后，马成了智慧的象征，而人成了下等动物。作者通过这样有趣的故事，讽刺了当时英国社会的种种弊病，如政客的尔虞我诈，富人的贪得无厌等。读者在赞叹作者的奇思妙想的同时，也能对当时的英国状况有个大概的了解。(With the exotic imagination, the author describes various strange things happening to the hero Gulliver when he traveled "Lilliput", "Brobdingnag" and "Houyhnhnms". For example, in the "Lilliput" where he can freely put various figures from the King to the civilian population in the palm of his hand to play; while in the "Brobdingnag", he could be like a child everywhere and controlled by others; when he came to "Houyhnhnms", he found that the horse become a symbol of wisdom, and people become the inferior animals. The author satires the maladies of the current British society such as the politician intrigues, the rich greedy and so on through such interesting stories. When praising the author's whimsy, the readers could also have a basic understanding to the current situation of the British.)
