Question 8 is based on the conversation you have just heard.

听力原文

W: (8) [I can’t believe that duck hunting is still legal in so many parts of the world.] The scientific evidence from countries like Australia, Canada, and the USA clearly indicates a decline in the birds’ numbers.

M: But can anyone be sure if the decline is really caused by the hunting or by climate change?

W: It’s caused by both in fact. We see more droughts in countries like Australia. Ducks are birds that feed and breed in areas where there is a lot of water, (9) [but their habitats have been shrinking in recent decades because of the droughts.]

M: And I guess with fewer places to inhabit, they concentrate in greater numbers in few areas, which surely makes them easier targets for the hunters.

W: It does. My grandfather was a duck hunter. He told me hunting ducks and geese began in the 19th century. They were an easily found and plentifully available food source in farming areas, especially for poor immigrants.

M: What do they use for hunting during that period?

W: They use new types of guns, and birds could easily be shot down in flight. And in such great numbers that commercial hunting of ducks and geese became an industry. (10) [Yet, there’s no commercial farming of these birds nowadays. Their meat is hardly eaten in Western countries.]

M: No, duck hunting seemingly exists as the continuation of a tradition.

W: Wild ducks have never been popular with farmers like my grandfather anyway because they sometimes destroy crops. (11) [In fact, farmers used to poison them in large numbers.]

M: That somehow doesn’t surprise me. Nobody places much value on the lives of these poor birds or on their meat.

8. What does the woman find unbelievable?

解析：D。在录音一开头女士就提到，简直不敢相信（can’t believe），世界上那么多地方猎鸭仍然是合法的，D项与此内容相符，其中Duck hunting，legal和many parts of the world为原词复现，因此选D。

错项排除：录音中虽然提到有科学证据表明鸭子数量减少（decline），但这只是女士表达震惊之后陈述的事实，并不是说数量减少让她觉得难以置信，故A项错误。B项利用录音中的climate change进行干扰，C项利用meat、Australia、Canada和the US进行干扰，但这都是录音中的个别词，女士并未对气候变化，西方国家不吃鸭肉等内容表示难以置信，故B、C两项排除。
