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. The researchers then tested how the monkeys combined — or added — the symbols to get the reward.
Here's how Harvard Medical School scientist Margaret Livingstone, who led the team, described the experiment: 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. For example, the number 7 would flash on one side of the screen and the other end would have 9 and 8. 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.
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. The underestimation was systematic: When adding two numbers, the monkeys always paid attention to the larger of the two, and then added only a fraction (小部分)of the smaller number to it.
"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."

答案
一.译文
猴子似乎对数字很有一套。
一组研究人员培训了三只恒河猴去处理26个明显不同的符号。这些符号由数字和精挑细选的字母组成,并且将0-25滴水或果汁作为奖励。然后研究人员测试了猴子是如何组合或添加这些符号以获得奖励的。
哈佛医学院的科学家 Margaret Livingstone,也是这个团队的领导者,是这样描述这个实验的:在它们的笼子里,给猴子们提供了触摸屏。在一部分屏幕上,将出现一个符号,而在另一侧则显示两个符号在一个圆圈里。例如,数字7将在屏幕的一侧出现,另一端是数字9和8。如果猴子触摸屏幕的左侧,它们将获得七滴水或果汁;如果他们选了圆圈,那么在这个例子中,它们将获得数字的总和——17。
在进行了数百次测试后,研究人员注意到:猴子会在一半以上的时间内获得更高的数值。这表明它们正在进行计算,而不仅仅是记住每种组合的数值。
当团队更仔细地检查实验结果时,他们注意到,当两个符号的数值接近时,与单个符号相比,猴子们往往会低估总和。这种情况是有选择性的。例如,它们认为13高于8和6的总和。这种低估是有系统的:当两个数字相加时,猴子总是注意两者中较大的一个,然后只加上较小数字的一小部分。
“这表明它们的大脑中有一种表示数量的方式,”Livingstone 博士说。“但在这个实验中,它们正在做的是更多地关注大数字而不是小数字。”
1.研究人员在测试猴子之前对它们做了什么?
A.他们饲喂了它们 B.他们给它们起了名字。
C.他们训练了它们。 D.他们测量了它们。
2.猴子在实验中是如何得到奖励的?
A.通过画一个圆。 B.通过触摸屏幕。
C.通过观看视频。 D.通过混合两种饮料。
3. Livingstone的团队对猴子有什么发现?
A.它们可以做基本的加法。 B.它们能懂简单的单词。
C.它们很容易记性数字。 D.它们可以长时间地保持它们的注意力,
4.这段文字可以出现在报纸的哪一部分?
A.娱乐 B.健康
C.教育 D.科学
二.答案和解析
1.C 细节题。根据文章第二段第一句中A team of researchers trained three Rhesus monkey 可知,研究人员在测试猴子之前对它们进行了训练。故正确答案为C。
2.B 细节题。根据第三段第四句中 If the monkeys touched the left side of the screen, they would be rewarded 可知,在这个实验中,猴子是通过触摸屏幕(touch a screen)的方式以获得相应的奖励的。A项,“通过画圆”;C项,“通过观看视频”;D项,“通过混合两种饮料”,均不符合文意。故正确答案为B。
3.A 细节题。根据第三段最后一句中 rewarded with the sum of the numbers 和第四段第一句中 indicating that they were performing a calculation 可知,猴子们可以做简单的加法运算。故正确答案为A。
4.D 推断题。文章主要介绍了一个研究团队对三只猴子进行的实验及其研究发现。如果这篇文章刊登在报纸上,最有可能被放在科学(Science)版块。A项,“娱乐”,B项,“健康”,C项,“教育”,均不符合题意,故A、B、C项均错误。故正确答案为D。
