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

老师我还是想借着这道题问您论证方法，课上您说必须高度概括且逻辑严密，那我在描述树的数量和报纸供给的问题的时候，我可不可以说：文章没有adress树的数量是否能持续供给足够的纸张，因为没有support说明树的数量是否足够能为当年提供5m份的报纸，如果可以…是否为未来继续提供

请问王文静老师 有两个问题1，上课您说因为是修饰need动词的所以不能在名词间做比较。那是不是可以理解为如果是比较修饰动词的就不能省略句子成分？2，b和e选项中的it很奇怪 这个有语法错误吗？这种从句中再提到主语可以直接用代词吗？还是得用that？

求教金老师～

老师我想问一下newspaper这道题，我的逻辑提取是：作者认为这家报社有自己的树 从而 可以保持供应新的报纸，所以回收旧报纸这个事是不必要的。我找的问题是forests的数量是否有可以消耗5m，如果有是否能够能够保证树的数量每年甚至每天提供报纸。此外我找不出其他问题了。

How many 3-letter codes can be formed by choosing, without replacement, 3 letters from the word “Banana”?想请问陆旭老师这道题用box method怎么解？

20og 741题，答案是A选项，想问一下B选项。希望张慧雯老师解答一下 我的理解在图二（字太多了140字放不下）

为什么不能选b选项呢？感觉b的结构更好一些而且后面加上he也没有问题：有七本书-4本文章和三本诗歌

请徐老师讲解一下这道题，谢谢！我算不出来选项里有的数不知道式子哪里列错了

我这道题n和k代了两个数进去但算出来五个选项没一个是和题目里的式子相等的……求教老师！谢谢！

老师这道题难道不是100减去2的倍数49个，3的倍数33个，再加上6的倍数16个最后得34个吗？求解答！谢谢！
