下面是对这几本书的简要介绍,请把它们对应的封面信息找出来:
小题1: In this collection, Bill Bryson is writing from home. We find he assesses life both in New England and in the contemporary United States. With the telescopic perspective(远望视角) of one who has stepped out of the American mainstream and come back after 20 years, Bryson holds the mirror up to U.S. culture and feel strange to his motherland.
小题2:This book is a guide to the world’s unspoilt sights and experiences. It presents one thousand fresh and fascinating alternatives to hundreds of well-known tourist destinations and sights, including alternatives to the Carnival in Rio and the beaches of Thailand, the most-visited national parks, over-rated restaurants and holiday sites.
小题3:Returning to the U.S. after 20 years in England, Bill Bryson decided to reconnect with his mother country by hiking the length of the 2100-mile Appalachian Trail. Awed by merely the camping section of his local sporting goods store, he still goes into the wilderness and learns hard lessons about self-reliance.
小题4: A travelogue by Bill Bryson is as close to a sure thing as funny books get. This book is no exception. Following an urge to rediscover his youth, the author leaves his native Des Moines, Iowa, in a journey that takes him to across 38 states in the country, which is like a small town in his opinion.
小题5:Born in Iowa, Bryson backpacked through Europe as a young man. While living in England some 20 years later, he revisited many of the same places from arctic Norway’s northern lights to romantic Capri in Italy. Here he jumps back and forth between old memories and new experiences.
