题型：名词解释 阅读理解。信息匹配。 下面是美国著名游记作家Bill Bryson的几本作品，首先请阅读它们的封面信息： ABCDEF 下面是对几本书的简要介绍，请把相关的内容和它们的封面信息匹配起来。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 comes back after 20 years, Bryson holds the mirror up to US culture and feels strange to his motherland.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, overrated restaurants and holiday sites.3. Returning to the US after 20 years in England, Bill Bryson decided to reconnect with his mother country by hiking the length of the 2, l00-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.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. 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. 查看答案
