托福阅读修辞目的题是阅读考试中比较常见的一种题型，tpo则是托福阅读备考最权威的材料，所以托福小编综合二者，为大家集中整理了tpo阅读中考察的修辞目的题及其对应的解析，供大家参考使用。本文带来的是TPO12-1的修辞目的题，一起来看看吧。
TPO12-1 Which Hand Did They Use
Paragraph 5
Tools themselves can be revealing. Long-handed Neolithic spoons of yew wood preserved in Alpine villages dating to 3000 B.C. have survived; the signs of rubbing on their left side indicate that their users were right-handed. The late Ice Age rope found in the French cave of Lascaux consists of fibers spiraling to the right, and was therefore tressed by a righthander.
9. In paragraph 5, why does the author mention the Ice Age rope found in the French cave of Lascaux?
○ As an example of an item on which the marks of wear imply that it was used by a right-handed person
○ Because tressing is an activity that is easier for a right-handed person than for a left-handed person
○ Because the cave of Lascaux is the site where researchers have found several prehistoric tools made for right-handed people
○ As an example of an item whose construction shows that it was right handed made by a right-person
解析：以Ice Age rope做关键词定位至最后一句，说rope是右旋的，说明是一个右撇子弄的，所以答案是D，一个例子，右撇子弄出来的。B和C都没说;而A说rope是右撇子的人用的，原文说rope是右撇子的人编制的，不是一回事
[5]工具的本身也会反映这一现象。新石器时代的紫杉木的长柄勺从史前3 000年一直完好的保存到现在;它左侧的磨痕证明了它们的主人惯用右手。在法国的拉斯科斯岩洞艺术找到的冰川时代末期的绳子是由向右旋转的纤维捆成的，当然也就证实了出自右撇子之手。
Paragraph 6
Occasionally one can determine whether stone tools were used in the right hand or the left, and it is even possible to assess how far back this feature can be traced. In stone toolmaking experiments, Nick Toth, a right-hander, held the core (the stone that would become the tool) in his left hand and the hammer stone in his right. As the tool was made, the core was rotated clockwise, and the flakes, removed in sequence, had a little crescent of cortex (the core's outer surface) on the side. Toth's knapping produced 56 percent flakes with the cortex on the right, and 44 percent left-oriented flakes. A left-handed toolmaker would produce the opposite pattern Toth has applied these criteria to the similarly made pebble tools from a number of early sites (before 1.5 million years) at Koobi For a, Kenya, probably made by Homo habilis. At seven sites he found that 57 percent of the flakes were right-oriented, and 43 percent left, a pattern almost identical to that produced today.
11. What was the purpose of Toth's tool making experiment described in paragraph 6?
○ To shape tools that could be used by either hand
○ To produce replicas of early tools for display in museums ○ To imitate the production of pebble tools from early sites
○ To determine which hand made the early tools
解析：先找到toth的实验在本段第二句，然后读这句话，发现整句话都是一个例子，然后往前看，也就是这段的第一句，说有时候能够确定到底是那只手用了这个工具，所以T的例子就是为说明这个的，所以答案是D，确定早期的工具是那只手做的
[6]偶尔也能确定石器是左手使用还是右手使用，甚至可以查出这些特征是在多久前的过去被留下的。在石器制造试验中，Nick toth,一个右撇子用左手拿着一个石胚(就是一块是要成为工具的石头)同时用右手抡锤。由于工具的作用，胚子顺时针的旋转的同时，小碎片一点点的去掉，在一侧留下月牙状的表层(石头胚子的表面)。Toth’s的敲打产生的碎痕56%留在了右侧的表面， 44%留在了左侧朝向的碎痕。一个左撇子工匠则会生产出相反的花纹，Toth将这种标准对照到数个在Kombi Fora(距今一百五十万年前)发现的类似卵石工具上，他在7个地点找到的57%的碎痕是右侧朝向，而百43%是左侧朝向，就和今天我们所生产的花纹一样。
Paragraph 7：
About 90 percent of modern humans are right-handed: we are the only mammal with a preferential use of one hand. The part of the brain responsible for fine control and movement is located in the left cerebral hemisphere, and the findings above suggest that the human brain was already asymmetrical in its structure and function not long after 2 million years ago. Among Neanderthalers of 70,000 – 35,000 years ago, Marcellin Boule noted that the La Chapelle-aux-Saints individual had a left hemisphere slightly bigger than the right, and the same was found for brains of specimens from Neanderthal, Gibraltar, and La Quina.
12. What is the author's primary purpose in paragraph 7?
○ To illustrate the importance of studying the brain
○ To demonstrate that human beings are the only mammal to desire fine control of movement
○ To contrast the functions of the two hemispheres of the brain
○ To demonstrate that right-hand preference has existed for a long time
解析：问整段的目的，找中心句，但不幸的是，第一句不是中心句，而且这段也没有中心句。但第一句说人类是唯一有左右撇子现象的动物，最后一句说早在很久以前就有了这种现象，能够对应选项D，其他都没说
[7]大约90%的现代人是右撇子;我们都是只是优先使用一只手的哺乳动物。大脑负责良好的控制行动的区域位于脑部的左半球，这也证明的人类大脑的机构和功能上的不对称性在两百万年前就已经定型了。在距今70 000到35 000年的尼安德特人中，Marcellin Boule发现La Chapelle-aux-Saints(某人种吧)个体的大脑左半球稍微比右边大一点，与之类似的也被发现在尼安德特人、直布罗陀人和拉昆尼亚人种的脑型中。
