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

看不懂，错选C

正确选项E取非怎么理解（我后来直接加强倒是想懂了）

如何解这两道题呢？

What is the median number of employees assigned per project for the projects at Company Z? 1, 25 percent of the projects at Company Z have 4 or more employees assigned to each project. 2,35 percent of the projects at Companny Z have 2 or fewer employees assigned to each project.

18！能被6整出，但不能被6的N+1次方整除，问n是多少？ 解释说求的18！有8个6的因子，哪八个阿？

原文我读到：不诚实就难达成政治compromise，结论是不诚实可以说明运作良好。 最后我剩下了A和C两个选项，A的意思是“达成Compromise不一定说明运作良好”；C的意思是“选民有其他判断标准”。 当时我的反应是“C中说到选民，跟原文意思关系较近”。 想听听老师的解题思路，以及我思路的问题。 谢谢老师。

原文 我是这么理解的 想让我解释为什么水藻擅长在慢流速水生长但是却在极度干旱的情况下（非常慢的水流速） 死翘翘 。 我觉得ABCDE 都无法解释 这个现象。。 D选项在说 什么在澳大利亚会经历一个完全的干旱然后又恢复。我感觉跟没说一样啊。 不知道是如何解释原文的 还希望老师解答 ^.^
