65. How did the author feel on his arrival in the Amazon? ( )
- A. Out of place.
- B. Full of joy.
- C. Sleepy.
- D. Regretful.
答案：A
答案句：We did not speak the local language, did not know the customs, and more often than not, did not entirely recognize the food. We could not have felt more foreign.
参考译文：我们不会说当地语言，不了解当地风俗，而且常常完全认不出那些食物。我们感到再陌生不过了。
定位线索：题干“on his arrival in the Amazon”→答案句取自第1段“We could not have felt more foreign”；文中“foreign”对应选项A“Out of place”（格格不入）。
解析：题干问作者到达亚马逊时的感受。答案句描述作者不会说当地语言、不了解风俗、认不出食物，并总结“We could not have felt more foreign”，直接对应选项A“Out of place”（感到格格不入）。选项B“Full of joy”、C“Sleepy”、D“Regretful”在原文中均无依据，属于无中生有。
66. What made that Amazonian evening wonderful? ( )
- A. He learned more about the local language.
- B. They had a nice conversation with each other.
- C. They understood each other while playing.
- D. He won the soccer game with the goal keeper.
答案：C
答案句：Then one perfect Amazonian evening, with monkeys calling from beyond the village green, we played soccer. I am not good at soccer, but that evening it was wonderful. Everyone knew the rules. We all spoke the same language of passes and shots. We understood one another perfectly.
参考译文：然后，在一个完美的亚马逊夜晚，猴子在村外绿地上方啼叫，我们踢了足球。我足球踢得不好，但那个晚上非常美妙。每个人都懂规则。我们都说着同样的传球和射门的语言。我们彼此完全理解。
定位线索：题干“that Amazonian evening wonderful”→答案句取自第3段“that evening it was wonderful”；文中“We understood one another perfectly”对应选项C“They understood each other while playing”。
解析：题干问什么使那个亚马逊夜晚美妙。答案句明确说“that evening it was wonderful”，并解释原因：“Everyone knew the rules”和“We understood one another perfectly”，即踢球时彼此理解，对应选项C。选项A“learned more about the local language”与原文“We did not speak the local language”矛盾；选项B“had a nice conversation”发生在球赛结束后，不是使夜晚美妙的原因；选项D“won the soccer game”原文未提及，属于无中生有。
67. Why was the author surprised at Juan's question about the moon? ( )
- A. The question was too straightforward.
- B. Juan knew so little about the world.
- C. The author didn't know how to answer.
- D. The author didn't think Juan was sincere.
答案：B
答案句：After I explained to Juan that yes, we did have a moon and yes, it was very similar to his, I felt a sort of awe (敬畏) at the possibilities that existed in his world. In Juan's world, each village could have its own moon. In Juan's world, the unknown and undiscovered was vast and marvelous.
参考译文：在我向胡安解释，是的，我们确实有月亮，而且和他们的很相似之后，我对他的世界里存在的可能性感到一种敬畏。在胡安的世界里，每个村庄都可能有自己的月亮。在胡安的世界里，未知和未发现的事物是广阔而奇妙的。
定位线索：题干“surprised at Juan's question”→答案句取自第4段“I felt a sort of awe”；文中“each village could have its own moon”对应选项B“Juan knew so little about the world”。
解析：题干问作者为何对胡安关于月亮的问题感到惊讶。答案句说明作者意识到在胡安的世界里“each village could have its own moon”，即胡安不知道地球只有一个月亮，说明他对世界了解甚少，对应选项B。选项A“too straightforward”原文未提及；选项C“didn't know how to answer”与原文“After I explained”矛盾；选项D“didn't think Juan was sincere”无中生有。

- A. To sort out what we have known.
- B. To deepen his research into Amazonians.
- C. To improve his reputation as a biologist.
- D. To learn more about local cultures.
答案：A
答案句：I began collecting newspaper articles about new species, new monkey, new spider … , and on and on they appear. My drawer quickly filled. I began a second drawer for more general discoveries: new cave system discovered with dozens of nameless species, four hundred species of bacteria found in the human stomach.
参考译文：我开始收集关于新物种的报纸文章，新猴子、新蜘蛛……它们不断出现。我的抽屉很快装满了。我开始为更普遍的发现准备第二个抽屉：发现了包含数十种无名物种的新洞穴系统，在人类胃中发现了四百种细菌。
定位线索：题干“initial purpose of collecting newspaper articles”→答案句取自第7段“I began collecting newspaper articles about new species”；文中“about new species”对应选项A“To sort out what we have known”（整理已知）。
解析：题干问作者收集报纸文章的初始目的。答案句表明作者开始收集关于新物种的文章，并分类整理（第一个抽屉装新物种，第二个抽屉装更普遍的发现），目的是整理已知的发现，对应选项A。选项B“deepen his research into Amazonians”、C“improve his reputation”、D“learn about local cultures”在原文中均无依据，属于无中生有。
69. How did those brilliant scientists make great discoveries? ( )
- A. They shifted their viewpoints frequently.
- B. They followed other scientists closely.
- C. They often criticized their fellow scientists.
- D. They conducted in-depth and close studies.
答案：D
答案句：Those scientists very often see the same things that other scientists see, but they pay more attention to them, and they focus on them to the point of exhaustion (穷尽), and at the risk of the ridicule of their peers.
参考译文：那些科学家常常看到其他科学家也看到的东西，但他们更关注这些东西，并且专注到穷尽的地步，甚至冒着被同行嘲笑的风险。
定位线索：题干“those brilliant scientists make great discoveries”→答案句取自第8段“Those scientists very often see the same things”；文中“focus on them to the point of exhaustion”对应选项D“conducted in-depth and close studies”（进行深入细致的研究）。
解析：题干问那些杰出科学家如何做出伟大发现。答案句指出他们“pay more attention”和“focus on them to the point of exhaustion”，即深入专注地研究，对应选项D。选项A“shifted their viewpoints frequently”与原文“see the same things”矛盾；选项B“followed other scientists closely”与原文“see the same things”但更专注不符；选项C“criticized their fellow scientists”原文只说“at the risk of the ridicule of their peers”，并非批评同行，偷换概念。
70. What could be the most suitable title for the passage? ( )
- A. The Possible and the Impossible
- B. The Known and the Unknown
- C. The Civilized and the Uncivilized
- D. The Ignorant and the Intelligent
答案：B
答案句：The question of what we know and do not know constantly bothered me. … We are repeatedly willing to imagine we have found most of what is left to discover. We used to think that insects were the smallest organisms (生物), and that nothing lived deeper than six hundred meters. Yet, when something new turns up, more often than not, we do not even know its name.
参考译文：我们已知和未知的问题不断困扰着我。……我们一再愿意想象我们已经发现了大部分有待发现的东西。我们过去认为昆虫是最小的生物，没有东西生活在六百米以下。然而，当新事物出现时，我们往往连它的名字都不知道。
定位线索：题干“most suitable title”→答案句取自第6段“what we know and do not know”和第9段“We are repeatedly willing to imagine we have found most of what is left to discover”；文中“what we know and do not know”对应选项B“The Known and the Unknown”。
解析：题干问最适合的标题。全文围绕“已知与未知”展开：作者从胡安的问题想到人类对世界的无知，收集新发现，并反思我们常以为已知很多，实则未知更多。答案句直接点明主题“what we know and do not know”，对应选项B。选项A“The Possible and the Impossible”、C“The Civilized and the Uncivilized”、D“The Ignorant and the Intelligent”均偏离文章核心，属于范围扩大或偷换概念。
