昨天偏头痛发作 晚上还练了口语我太佩服自己啦。。。（以前都是啥时候发作啥时候开始睡觉的 特别难受）---- 10.07 国庆最后一天 反正跟我没关系 ---- TPO12 第一篇 Which Hand Did They Use? 用时20min差不多刚好 大错4。。。 Paragraph 1：We all know that manymore people today are right-handed than left-handed. Can one trace this same pattern far back in prehistory? Much of theevidence about right-hand versus left-hand dominance comes from stencils and prints found in rockshelters in Australia and elsewhere, and in many Ice Age caves inFrance, Spain, and Tasmania. When a left hand has been stenciled, this impliesthat the artist was right-handed, and viceversa. Even though the paint was often sprayed on by mouth, one can assume that the dominant hand assistedin the operation. One also has to make the assumption that hands were stenciled palm downward—a left handstenciled palm upward might of course look as if it were a right hand. Of 158 stencils in the French cave of Gargas, 136 have been identified as left, and only 22 as right;right-handedness was therefore heavily predominant. 2. It can be inferred from paragraph 1 that even when paint wassprayed by mouth to make a hand stencil 为啥题目里是嘴巴。。又不是一个月。。。吐血 搞得我根本没看懂 ○ there was no way to tellwhich hand was stenciled ○the stenciled hand was theweaker hand ○ the stenciled hand wasthe dominant hand ○artists stenciled moreimages of the dominant hand than they did of the weak Paragraph 2：Caveart furnishes other types of evidence of this phenomenon. Most engravings, forexample, are best lit from the left, as befits the work of right-handedartists, who generally prefer to have the light source on theleft so that the shadow of their hand does not fall on the tip of the engravingtool or brush. In the few cases wherean Ice Age figure is depicted holding something, it is mostly, though notalways, in the right hand. 5. All of the following arementioned in paragraphs 1 and 2 as evidence of right-handedness in art and artistsEXCEPT○ the ideal source oflighting for most engravings ○the fact that a left handstenciled palm upward might look like a right hand ○ the prevalence of outlinesof left hands ○ figures in prehistoricart holding objects with the right hand Paragraph 5：Toolsthemselves can be revealing. Long-handed Neolithic spoons of yew wood preservedin Alpine villages dating to 3000 B.C. have survived; the signs of rubbingon their left side indicate that their users wereright-handed. The late Ice Age rope found in the French cave of Lascaux consists of fibers spiraling to the right, and was therefore tressedby a righthander.9. In paragraph 5, why does the author mention the Ice Age rope foundin the French cave of Lascaux ?○As an example of an item on which the marks ofwear imply that it was used by a right-handed person ○ Because tressing is an activity that is easier for a right-handedperson than for a left-handed person ○ Because the cave of Lascaux is thesite where researchers have found several prehistoric tools made forright-handed people ○As an example of an item whose constructionshows that it was right handed made by a right-person Paragraph 7：About90 percent of modern humans are right-handed: we are the only mammal with apreferential use of one hand. The part of the brainresponsible for fine control and movement is located in the left cerebral hemisphere, and the findings above suggest that the human brain wasalready asymmetrical in its structure and functionnot long after 2 million years ago. Among Neanderthalers of 70,000 – 35,000years ago, Marcellin Boule noted that the LaChapelle-aux-Saints individual had a left hemisphere slightly bigger than the right, and the same was found for brains of specimensfrom Neanderthal, Gibraltar , and La Quina. 12. What is the author'sprimary purpose in paragraph 7? ○To illustrate the importance of studying thebrain ○ To demonstrate that human beings are the onlymammal to desire fine control of movement ○ To contrast the functions of the twohemispheres of the brain ○To demonstrate that right-hand preference hasexisted for a long time
