Archaeology as a profession faces two major problems. First, it is the poorest of the poor. Only paltry sums are available for excavating and even less is available for publishing the results (5) and preserving the sites once excavated. Yet archaeologists deal with priceless objects every day. Second, there is the problem of illegal excavation, resulting in museum-quality pieces being sold to the highest bidder. (10) Iwould like to make an outrageous suggestion that would at one stroke provide funds for archaeology and reduce the amount of illegal digging. Iwould propose that scientific archaeological expeditions and governmental (15) authorities sell excavated artifacts on the open market. Such sales would provide substantial funds for the excavation and preservation of archaeological sites and the publication of results. At the same time, they would break the illegal (20) excavator's grip on the market, thereby decreasing the inducement to engage in illegal activities. You might object that professionals excavate to acquire knowledge, not money. Moreover, ancient artifacts are part of our global cultural heritage, (25) which should be available for all to appreciate, not sold to the highest bidder. Iagree. Sell nothing that has unique artistic merit or scientific value. But, you might reply, everything that comes out of the ground has scientific value. Here we part company. (30) Theoretically, you may be correct in claiming that every artifact has potential scientific value. Practically, you are wrong. I refer to the thousands of pottery vessels and ancient lamps that are essentially duplicates of (35) one another. In one small excavation in Cyprus, archaeologists recently uncovered 2,000 virtually indistinguishable small jugs in a single courtyard. Even precious royal seal impressions known as I'melekh handles have been found in abundance (40) —more than 4,000 examples so far. The basements of museums are simply not large enough to store the artifacts that are likely to be discovered in the future. There is not enough money even to catalog the finds; as a result, they 368 (45) cannot be found again and become as inaccessible as if they had never been discovered. Indeed, with the help of a computer, sold artifacts could be more accessible than are the pieces stored in bulging museum basements. Prior to sale, each could be (50) photographed and the list of the purchasers could be maintained on the computer. A purchaser could even be required to agree to return the piece if it should become needed for scientific purposes. It would be unrealistic to suggest that illegal (55) digging would stop if artifacts were sold on the open market. But the demand for the clandestine product would be substantially reduced. Who would want an unmarked pot when another was available whose provenance was known, and that was dated (60) stratigraphically by the professional archaeologist who excavated it? The primary purpose of the passage is to propose (A) an alternative to museum display of artifacts (B) a way to curb illegal digging while benefiting the archaeological profession (C) a wayto distinguish artifacts with scientific value from those that have no such value (D) the governmental regulation of archaeological sites (E) a new system for cataloging duplicate artifacts

老师好…这道CR题错选A能求解释一下么？谢谢！

请教唐瑭老师：og上的题，答案是D，选了A。不明白D为什么对，是因为最后一句的Although强调的是前半句吗？although一般强调后半句还是前半句？

老师这道题不知道该怎么解！我是这么算的 6!/3!*3!得出来的结果再乘以2，等于40，但答案是30，不知道是哪里算错了，还是我理解错了，希望老师解答！

老师图片里是作文的标题和我在规定时间内写的东西，您看看我错误找全了吗？找错的思维有没有跳跃？第一段和第二段的论证可以这样写吗？以及我每次都是三十分钟压线写完，字数也不多，请老师给我提一些思维和写作上的建议，谢谢！

老师这道题题目有点看不懂，算不到B选项，不知道是题目理解错了还是公式用错了，求讲解

老师能讲解一下这道题吗？

老师您好，这道题的题目有一点看不懂，请问是什么意思以及为什么选d？

老师您好，我想问一下这道题E为什么有利于支持文中观点？

@英吉老师，我最近在看您的录播逻辑网课，您不推荐我们回读。但是我在日常练习的时候做不到读一遍就能弄懂句间关系，或者读第一遍有时候连句子一起都不太清楚。那我们想要练就读一遍就可以了解句间关系的能力，并且用在考场的话，平时可以怎样练习呢？

老师请问这个“or”应该怎么算？
