He was confident that he could succeed in this daring, unconventional plan.”可知,约翰内斯·弗里茨的计划是带领秃鹮沿着一条新的路线迁徙。故选B项。 2.A　词义猜测题。根据画线词下文“…causing the birds to disappear entirely from the wild.”可知,欧洲人不停地猎杀这些鸟,并在野外杀死了最后一只,故画线词与destroyed“毁灭,破坏”意义相近。故选A项。 3.D　推理判断题。根据文章第四段“But the route he originally taught the ibises does not work successfully. With climate change warming the area where the birds spend summer, they now start their migration at the end of October instead of the end of September.”可推知,弗里茨先生最初寻找的路线是无效的,因为夏季栖息地的温度升高导致秃鹮的迁徙时间延后。故选D项。 4.B　推理判断题。根据文章第二段“Determined to save them, he decided to teach the birds a new, safer migration route by guiding them himself in a tiny aircraft. He was confident that he could succeed in this daring, unconventional plan.”可知,约翰内斯·弗里茨教秃鹮新的迁徙路线。由此推知,他是有创新想法的人。故选B项。 Ⅵ.【文章大意】 本文是一篇说明文,主要讲的是废弃捕蟹笼的危害和解决方案。 1.F　空前“Crab traps (捕蟹笼) work like this: crabs crawl in, but they don’t crawl out.”说明捕蟹笼可 ... ...
