32. What did the researchers do to the monkeys before testing them?
- A. They fed them.
- B. They named them.
- C. They trained them.
- D. They measured them.
答案：C
答案句：A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 0-25 drops of water or juice as a reward.
参考译文：一组研究人员训练了三只恒河猴，让它们将26个由数字和特定字母组成的清晰不同的符号与0-25滴水或果汁的奖励联系起来。
定位线索：题干“What did the researchers do to the monkeys before testing them”→答案句“A team of researchers trained three Rhesus monkeys”；文中“trained”对应选项C“They trained them”（训练）。
解析：题干问测试前研究人员对猴子做了什么，答案句直接说明研究人员“trained”（训练）了猴子，与选项C“They trained them”完全对应。选项A“fed them”（喂食）、B“named them”（命名）、D“measured them”（测量）在原文中均未提及，属于无中生有。
33. How did the monkeys get their reward in the experiment?
- A. By drawing a circle.
- B. By touching a screen.
- C. By watching videos.
- D. By mixing two drinks.
答案：B
答案句：In their cages the monkeys were provided with touch screens. On one part of the screen, a symbol would appear, and on the other side two symbols inside a circle were shown. … If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice; if they went for the circle, they would be rewarded with the sum of the numbers—17 in this example.
参考译文：在笼子里，猴子们被提供了触摸屏。屏幕的一部分会出现一个符号，另一侧则显示一个圆圈内的两个符号。……如果猴子触摸屏幕左侧，它们会得到七滴水或果汁的奖励；如果它们选择圆圈，它们会得到数字之和——在这个例子中是17。
定位线索：题干“How did the monkeys get their reward”→答案句“If the monkeys touched the left side of the screen they would be rewarded”；文中“touched the screen”对应选项B“By touching a screen”（通过触摸屏幕）。
解析：题干问猴子如何获得奖励，答案句明确指出猴子通过“touched the screen”（触摸屏幕）获得奖励，与选项B“By touching a screen”直接对应。选项A“drawing a circle”（画圆圈）是干扰项，原文中圆圈是屏幕上的显示内容，不是猴子的动作；C“watching videos”（看视频）和D“mixing two drinks”（混合饮料）在原文中均未提及，属于无中生有。
34. What did Livingstone's team find about the monkeys?
- A. They could perform basic addition.
- B. They could understand simple words.
- C. They could memorize numbers easily.
- D. They could hold their attention for long.
答案：A
答案句：After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, not just memorizing the value of each combination.
参考译文：在进行了数百次测试后，研究人员注意到，猴子选择较高数值的次数超过一半，这表明它们在进行计算，而不仅仅是记住每个组合的数值。
定位线索：题干“What did Livingstone's team find about the monkeys”→答案句“the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation”；文中“performing a calculation”对应选项A“They could perform basic addition”（它们能进行基本加法）。
解析：题干问Livingstone团队发现了猴子什么特点，答案句指出猴子“performing a calculation”（进行计算），且前文实验描述中猴子需将符号相加（如7和9+8），说明它们能进行基本加法，与选项A对应。选项B“understand simple words”（理解简单单词）在原文中未提及；C“memorize numbers easily”（容易记住数字）被答案句明确否定（“not just memorizing”）；D“hold their attention for long”（长时间保持注意力）在原文中无依据，属于无中生有。
35. In which section of a newspaper may this text appear?
- A. Entertainment.
- B. Health.
- C. Education.
- D. Science.
答案：D
答案句：Monkeys seem to have a way with numbers. … A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 0-25 drops of water or juice as a reward. … Here's how Harvard Medical School scientist Margaret Livingstone who led the team, described the experiment: … After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, not just memorizing the value of each combination. … When the team examined the results of the experiment more closely, they noticed that the monkeys tended to underestimate(低估)a sum compared with a single symbol when the two were close in value—sometimes choosing, for example, a 13 over the sum of 8 and 6. … “This indicates that there is a certain way quantity is represented in their brains, ”Dr. Livingstone says. “But in this experiment what they're doing is paying more attention to the big number than the little one.”
参考译文：猴子似乎对数字有一套。 … 一组研究人员训练了三只恒河猴，将26个由数字和选择性字母组成的明显不同的符号与0-25滴水或果汁作为奖励联系起来。 … 以下是领导该团队的哈佛医学院科学家玛格丽特·利文斯通描述实验的方式： … 在运行了数百次测试后，研究人员注意到，猴子在超过一半的时间里会选择更高的数值，这表明它们在进行计算，而不仅仅是记住每种组合的值。 … 当团队更仔细地检查实验结果时，他们注意到，当两个数值接近时，猴子倾向于低估一个总和与单个符号相比——例如，有时选择13而不是8和6的总和。 … “这表明数量在他们大脑中有某种特定的表示方式，”利文斯通博士说。“但在这个实验中，他们所做的是更多地关注大数字而不是小数字。”
定位线索：题干“In which section of a newspaper”→文章整体内容为科学实验报道；文中“A team of researchers trained...”“the researchers noted...”“the team examined...”对应选项“Science”；文中“researchers”“experiment”对应选项“Science”。
解析：题干问文章可能出现在报纸的哪个栏目，属于主旨题。文章通篇描述了一项关于猴子数字能力的科学实验，包括研究人员、实验方法、结果和科学家的评论，这些内容明显属于科学报道范畴。选项D“Science”（科学）正确。选项A“Entertainment”（娱乐）、B“Health”（健康）、C“Education”（教育）均与文章内容无关，属于无中生有。文章未涉及娱乐、健康或教育主题，故排除。
