英语的一道阅读题,我认为老师的答案是错的
最近英语期初考试有一篇讲一种鸟的阅读通篇基本用单数来写,有一道题是how many birds can smell things in the world 我根据文章中一句There are only a few kiwis.答only a few ,and they're all kiwis老师算错说答案是only one这根本不可能嘛!难道世界上就一只kiwi有嗅觉?闻所未闻!老师还说这里的问题是和how many kinds of birds can smell things in the world是一样的!简直就是搪塞学生的问题!这能一样么?

答案

老师对,根据it is the only bird in the world that can smell things .the only bird说的就是kiwi,因为加the了.是特指
