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

请问这题中“explore”的动发者为什么是“Lina”呢？我在读A选项时总觉得选项中explore的动发者是“A group of films” 因为觉得explore前面的主体是“A group of films”, 而 in 1970 和 Lina 都是修饰films的。

@英吉 请问这题E选项错在哪里呢？能麻烦您解释一下吗？谢谢！

老师您好，实在是有点看不懂这道题的问题到底要我算什么，求解，谢谢！

王文静老师，我是刚刚在上海结束了封闭班的学生，周梦瑶，^_^^_^不知道您还记不记得我，我准备在9.1日参加考试，我做了一个大致的复习计划，但是还不清楚，是否正确，或者有没有什么疏漏的地方，还想请您帮忙看一下，帮我修改斧正一下，非常感谢老师^_^^_^^_^

老师您好，我看了您明星课上给的题目答案过程，但是还是不太清楚自己的过程哪里出错了。能麻烦您解释一下吗？谢谢！ （我用紫色笔框出了我的解题过程）

请问老师，原文题目当中【即A选项】中estimates后面的and为什么前面没有逗号呢？这样没有逗号不就是跟从句后面surpassed并列了吗？可本应该是跟主句谓语并列呀？

请问一下老师此题中的选项B中的’ which were’的which不应该是要遵照定语从句中就近原则，来指代Richard Nixon吗？【我清楚人应该用whom来指代】可是为什么这里没有遵照就近原则呢？

老师您好，我听了您的基础课解释的为什么分子只能有一个C[1,60]，但是还是不太理解。在第一个班（e.g. senior）sibling里选一个是C[1,60]，另一个班就是C[1,1] 而不是C[1,60]呢？ 我不懂的点在于 题目说是两次选取都是random的，也就是在图中大写A里选出姐姐，不代表一定会在小写a 里选中她对应的妹妹呀？ 这里我比较糊，能麻烦老师您解释一下吗？谢谢！

老师，数学基础课这题 在可重复使用letter时，为什么在two letter code时不用✖️A[2,2]，在three letter code时 不用✖️A[3,3]呢？ 我是知道 当需要“选，拿，取”时，我们要用C，；但是我对具体什么时候需要用到A 还是有些模糊。能不能麻烦老师您解释一下我们什么时候会用到A？特别是在我们已经用到C后，什么时候需要在C基础上 再✖️A（e.g. C[3,26]✖️A[3,3]）？ 谢谢！

老师，能麻烦您解释一下您在数学基础课上说的 “因为k+7 可以整除3，所以整个式子可整除3” 的原因是什么吗？这里为什么可以直接判断出 k（k+7）可以被2整除呢？谢谢！
