We’ve just seen two contemporary large birds that cannot fly: the emus and the ostrich. Over here is an interesting specimen from the past. This stuffed animal is not the giant penguin it appears to be, but an auk. This particular kind of auk is very rare—only 78 skins are known to exist and most are not preserved as well as this one. The great auk, as you can see, was a rather large bird, and it couldn’t fly either. However, evidence suggests that the auk was an excellent swimmer and diver. Unfortunately, those abilities did not protect it from being easy prey for hungry sailors who years ago sailed the very cold and often icy waters of Greenland, Iceland, and Scotland. In fact, records indicate that the auk was rather tasty and that its eggs—Excuse me that its eggs and feathers were useful as well. Still, it isn’t clear what other factors led to the big bird’s demise around 1844, the last time anyone reported seeing one. Of course, we believe it’s important to take extra precautions to preserve the remaining great auk skins. After all, these specimens should prove invaluable for future scientific research. Does anyone have any questions before we move on to our next bird exhibit?
1. What is the talk mainly about?
2. Why was it easy to capture auks?
3. Why did the sailers hunt the auk?
4. Where did the auk live?

选项 A、They were poor swimmers.
B、They couldn’t fly.
C、Their bright colors made them easy to see.
D、They moved in large groups.

答案 B

解析 这段话一开始就指出,他们所讨论的海雀是一种不会飞的大鸟。说话者后来又提到,虽然海雀擅长游泳和潜水,但这些都不能保护它不被捕捉。可见,它之所以容易被捕捉,还是因为它不会飞的缘故,因此选B。这道题使用排除法更容易锁定正确答案。
