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

语法题目，请指定王文静老师回答。 问题语法讲义-修饰-第十题-Psychiatrist题目，我感觉选项A.B都是一样的意思，而且2个选项都没有问题，不知道该如何取舍。谢谢

老师，这道题怎么解的？我自己的理解是，速度慢的机器有1到3台，把每台多出来的1小时加在一起除4，求得的平均值就是小数点后的数字。所以求的平均值最小是0.25不可能是0.2因此选项A，7.2是不可能的。但是不知道这道题是不是这么理解的。

老师，这题答案是D，但我觉得是C。题中说大于10小于100的整数，应该是89个，掉到过来98+9，个位数是7

20题我计算是95页，但是答案是B，99页，不知道怎么算出来的。

老师25题答案给的是30%.可是我怎么算都应该是40%呢？我算错了吗？应该怎么算？

老师这道题没明白是什么意思

老师，第12题我没明白是什么意思

这个是Tina 老师在语法课上讲的一道题，不知道为什么搜不出来。想问一下，正确答案B 选项中的begun为什么不是过去分词引导的状语从句修饰the autographed quilt? Tina 老师在课上讲的是：begun是就近修饰名词fad的，我就很迷茫。我一直记得您讲过过去分词和现在分词作状语是修饰不到SVO 的O 上的，那这个为什么例外呢?谢谢您!
