【答案解析】原文： The saying "blind as a bat" simply isn’t correct. The truth is that all 1,100 bat species can see and often their vision is pretty good, although not as excellent as other night-hunting animals. There are two main groups of bats, which are believed to have evolved independently of each other, but both from a common ancestor. The first group, known as "mega bats", are mostly medium-sized or large bats who eat fruits, flowers, and sometimes small animals or fish. These species have distinctive visual centers and big eyes. They use senses of vision and smell to capture their prey. For example, Flying Foxes not only see well during daylight, but can also distinguish colors. They actually rely on their daylight vision and cannot fly during the night with no moonlight. The second group, called "micro bats", are smaller in size and mostly eat insects. These species use echo location to find their way and identify food. Scientists have proven that despite their poorly developed small eyes, these bats still can see during the day. When we consider the nightly lifestyle of these bats, we will see they have to be sensitive to the changing light levels because this is how they sense when to start hunting. Moreover, vision is used by micro bats to travel over long distances beyond the range of echo location. So the truth is, there are no bats which are naturally blind. Some species use their sense of hearing more than their eyes as a matter of adaptation to a particular lifestyle, but their eyes are still functional. 9. What do we learn about mega bats? 10.How do micro bats find their way and identify food? 11.Why do some species of bats use their sense of hearing more than their eyes?文章介绍蝙蝠有两大类，第一类是巨型蝙蝠，多为中型或大型蝙蝠，以水果、鲜花为食，有时也捕食小动物或鱼类。这些物种(巨型蝙蝠)具有独特的视觉中心和大眼睛。它们使用视觉和嗅觉来捕捉猎物。由此可知选项D正确，distinctive visual centers…big eyes都是文中的原词，只是顺序不同。同时据此排除选项A、B。文章开头介绍说两大类蝙蝠是从同一祖先独立进化而来的，故选项C错误。
【正确答案】
A

【正确答案】
C
