TPO5-2 The Origin of the Pacific Island People
文章中对太平洋岛屿上居民的起源的多种推测轮番上阵，不要被乱花迷住双眼，要宏观把握文章主旨，就要找准作者的落脚点。
1)Speculation on theorigin of these Pacific islanders began as soon as outsiders encountered them, in the absence of solid linguistic, archaeological, and biological data, many fanciful and mutually exclusive theories were devised. (多种猜测即将拉开序幕，注意这些猜想彼此之间的关系。)
2)Many older theories implicitly deprecated the navigational abilities and overall cultural creativity of the Pacific islanders. For example,……. Contrary to these theorists, the overwhelming evidence of physical anthropology, linguistics, and archaeology shows that the Pacificislanders came from Southeast Asia and were skilled enough as navigators to sail against the prevailing winds and currents.(不管之前older theories说的有多绘声绘色，注意段尾最终的总结。这也成为本段两道细节题的考点。)
3) It is now generally believed that these prerequisites originated with peoples speaking Austronesian languages (a group of several hundred related languages) and began to emerge inSoutheast Asia by about 5000 B.C.E.(speaking Austronesian languages只是一个特点，而非先决条件，排除题迷惑点。)
4) Detailed studies of the winds and currents using computer simulations suggest that drifting canoes would have been a most unlikely means of colonizing the Pacific.(最高级加否定，排除题设置点。)
5) As Patrick Kirch,an American anthropologist, points out, rather than being brought by rafting South Americans, sweet potatoes might just have easily been brought back by returning Polynesian navigators who could have reached the west coast of South America.(分析清楚被插入语打碎的这个句子，提炼P.K到底持哪种观点。修辞目的题来源。)
