Lions have disappeared from much of Africa, but for the past few years scientists have wondered if the big cats were hanging on in remote parts of Sudan and Ethiopia. (5) Continuous fighting in the region has made surveys difficult. (6) But scientists released a report Monday documenting, with hard evidence, the discovery of "lost lions." A team with Oxford University's Wildlife Conservation Research Unit, supported by a charity organization, spent two nights in November camping in a national park in northwest Ethiopia, on the Ethiopia-Sudan border. (7) The researchers set out six camera traps, capturing images of lions, and they identified lion tracks. The scientists concluded that lions are also likely to live in a neighboring national park across the border in Sudan. The International Union for Conservation of Nature had previously considered the area a "possible range" for the species, and local people had reported seeing lions in the area, but no one presented convincing evidence.

详解详析
5. What has made it difficult to survey lions in remote parts of Sudan and Ethiopia?
C)。(详解）新闻开头提到,狮子在非洲大部分地区已经消失,但是在过去的几年,科学家们曾经猜想,在苏 和埃塞俄比亚的偏远地区是否会有狮子活动的迹象。然后,新闻提到这一地区战乱频繁,使科学家们 的调查举步维艰,因此答案为C)。
6. What was the main purpose of the research?
D)。(详解)新闻中提到,科学家在周一发布了一份报告,用强有力的证据证明发现了“消失的狮子”。接 下来描述了发现的过程:牛津大学野生动物保护与研究团队在位于苏埃边境的埃塞俄比亚西北部的国 家公园守候了两个晚上,发现了狮子的踪迹。由此可知,这一研究的主要目的就是找到“消失的狮子”存 在的证据,因此答案为D)。
7. What did the researchers find in the national park?
A)。(详解)新闻中提到,研究者们在国家公园设置了6个相机陷阱,捕捉到了狮子的图像,发现了狮子的 踪迹,因此答案为A)。
