能正确表示动物与其气体交换部位的是（ ）
①蚯蚓---体壁 ②鲫鱼---鳃 ③家鸽---肺和气囊 ④青蛙---鳃和皮肤 ⑤家兔---肺．
A．①③⑤
B．①②④
C．①②⑤
D．②③⑤
A、①蚯蚓属于环节动物，它没有专门的呼吸器官，依靠体壁与外界环境进行气体交换，③家鸽每呼吸一次，气体两次经过肺，在肺里进行两次气体交换，而没有气囊⑤家兔是哺乳动物，有肺呼吸．故不符合题意．
B、①蚯蚓依靠体壁与外界环境进行气体交换，②鲫鱼生活在水中，用鳃呼吸，④青蛙幼体生活在水中，用鳃呼吸，成体既能生活在水中，也能生活在潮湿的陆地上，主要用肺呼吸，故不符合题意．
C、①蚯蚓用体壁进行气体交换，②鲫鱼用鳃呼吸，⑤家兔用肺呼吸，符合题意．
D、②鲫鱼用鳃呼吸，③家鸽用肺和气囊呼吸不正确，家鸽在肺里进行气体交换，⑤家兔用肺呼吸，故不符合题意．
故选C
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：
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. |
