What social function may the strangely shaped tail feathers have?
Chinese scientists have discovered strange-shaped tail feathers in 100 million-year-old ambers which do not belong to any existing or known birds, and they believe that the streamer-like feathers, in addition to helping the birds to fly in the right direction, could have a social function. Today’s male birds use beautiful tail feathers to attract females in courtship. These once colorful feathers may have had a similar use.
选项
A、To attract the opposite sex.
B、To help the birds to perch on ambers.
C、To distinguish the birds from others.
D、To help control the direction in which the birds fly.
答案
A
解析
特定信息的找寻与判断。根据原文“the streamer-like feathers, in addition to helping the birds to fly in the right direction, could have a social function”可知,这种鸟尾巴上的羽毛能帮助其掌握飞行的方向,可能还有社交作用,即前者并非社交作用,选项D错误。该句之后为对社交作用的阐述,“Today’s male birds use beautiful tail feathers to attract females in courtship. These once colorful feathers may have had a similar use”,表明这种羽毛可能与现在的鸟类羽毛有相似的社交功能,即吸引异性,选项A正确。选项B和选项C并非原文所表达的内容。因此,选项A为最佳选项。
