33*. American Native Origin的研究

　　by qq341163712(v32)

　　说是由于坐船去美洲大陆的说法太不靠谱，科学家在多少年以前一直对此不以为然，普遍认为是在冰川时期从阿拉斯加走过去的。

　　然后根据研究，在多少年之前，不具备走过去的条件。然后在多少年(大概1000年左右吧)之后，就有证据表明美洲有人啦。

　　所以他们得在这段时间从北走到南。作者认为这样是feat(还是什么词的)，大概就是说这个速度很不靠谱。

　　于是第二段就开始讨论，有人就觉得从海上划船过去挺好，不过划船的话，很难找到证据来证明。(这边是有题的，好像是个细节题)

　　因为有当初证据的地方被水淹了，成深海区啦。在最后就说什么，就挺有必要去探索深海区，发掘证据什么的。

　　Q1：主旨题，其中有一项就是给理由，要去探索深海区什么的，不过狗主没选这个，大家可以讨论下。

　　Q2：针对黄色部分的细节题

　　考古

　　人类何时到达美洲，还有争议。考古的发现显示的最早时间的14,700年前。

　　第 一个假说是，通过陆路。说人们可以通过COASTAL JOURNEY 沿海岸走，因为爱斯基摩皮船(kayak)太小不太可能做跨海的交通工具。由于ice age，人类不可能于15,700年前通过陆路到达美洲(讲了原因“冰呀，海呀什么的”)。还讲了什么向南走，一个月可以走20里。多少年后到了南美。但是旧观点有个问题，就是人移动的速度太快了不合理

　　第二个假说是，学者F提出的新观点：通过海路，支持的理由是坐船移动的速度合理。但是因为冰河融化，当时沿岸可住人的地区现在都在海底，即使有证据也被淹没了。转折，最新海底考古有证据支持沿岸的确有住人，但是这个证据对於支持海路说还是薄弱的。结论是陆路或海路尚无定论，但对於F学者提出的海路迁移开始时间点(14,000~15,000年前)是普遍被接受的。

　　Q1：有主旨题。

　　Q2：第二段全(假说部分)highlight了，问作用。

　　Q3：好像有个15,000到15,500的数字题~

　　参考文献

　　Transportation to the New World is a big topic for debate. 提出问题If the early Americans did cruise巡航 around the continent in canoes and kayaks, might the first settlers have arrived by boat as well? For decades the archaeological community rejected this notion (Ice Agehunters could never have carried all their weapons and lt over mammoth meat in such tiny boats!), but in recent years the idea has gathered more support.旧观点反对经由海路假说

　　One reason for the shift: the nagging困扰的 problem of just how fast people can make the journey from Alaska toTierra del Fuego. 旧观点的问题症结点Consider Dillehay&aposs 14,700-year-old Monte Verde site. According to the previously accepted timeline, people could have made the journey from Asia on foot no earlier than 15,700 years ago(bore this time, the ice sheets extending from the North Pole covered Alaskaand Canada completely, making a land passage impossible). If this entry date is correct, the Monte Verde find would indicate that the first settlers had to make the 12,000 -mile trip through two continents in only 1,000 years. In archaeological time, that&aposs as fast as Marion Jones(地球上跑得最快的女人). 提出反对旧观点的理由:行走速度太快? One way to achieve this pace , however,would be by traveling along the Pacific coastlines of North and SouthAmerica in boats. 转折, F提出海路假说新观点Knut Fladmark, a professor of archaeology at Simon Fraser University in Burnaby, BC, first suggested this possibility in the 1970s and remains an advocate of a coastal entry into the Americas. If people had a reason to keep moving, he says, they could have traversed both continents in 100 years. 支持理由:速度符合Fladmark estimates that traveling at a rate of 200 miles a month would have been quite reasonable; the settlers no doubt stopped during winter months and probably stayed in some spots for a generation or so if the local resourceswere particularly tempting. Fladmark&aposs theory, though enticing won&apost be easy to prove. 让步,提出缺陷Rising sea levels from the melting Ice Age glaciers in undated thousands of square miles along the Pacific coasts of both continents. Any early sites near the ocean that were inhabited bore 13,000 years ago would now be deep underwater. 新观点的弱点Recently a few enterprising researchers have attempted to dredge挖出 up artifacts from below the Pacific. In 1997, for example, Daryl Fedje, an archaeologist with Parks Canada (which runs that country&aposs national parks system), led a team that pulled up a small stone tool from 160 feet underwater just off the coast of British Columbia. 提出证据证明新观点The single tool, which Fedje estimates to be around 10,200 years old, does establish that people once lived on the now submerged land but reveals little about the culture there. Excavating underwater sites might turn out to be the only way to prove when humans first arrived on this continent.提出对证据的质疑? And for many researchers this is still a very open question 因为证据力不足，海路说尚未定论, with answers ranging from 15,000 years ago to as far back as 50,000 years ago. When Fladmark first proposed the idea of a coastal migration, the entry date of 14,000 or 15,000 years ago was orthodoxy.公认的,持普遍赞同的

　　结论是有关F的新观点的开始时间点(14,000~15,000年前)是被普遍接受的
