Contrary to the arguments of some that much of the pacific was settled by Polynesians accidentally marooned after being lost and adrift, it seems reasonable that this feat was accomplished by deliberate colonization expeditions that set out fully stocked with food and domesticated plants and animals.

　　词汇讲解：

　　maroon作动词，表示“被困于荒无人烟且无法脱身的地方”，比如：The car broke down leaving usmarooned in the middle of nowhere. 汽车坏了，我们被困在茫茫荒野中。生活中maroon也可以表示一种颜色，就是“栗色”。

　　deliberate作形容词，表示“有意的”，比如：a deliberate act of disobedience 故意的违抗行为。deliberate也可以作动词，表示“仔细考虑;商议”，比如：We really can’t afford to deliberate any longer. 我们真的不能再仔细考虑了。They met to deliberate on possible solutions to the problem. 他们聚在一起仔细商讨这个问题的可能解决办法。

　　domesticated plants and animals通常指的是已培育好的植物和已驯化的动物。domesticate作动词，本意就是“驯养”。

　　句子分析：

　　Contrary to the arguments of some that much of the pacific was settled by Polynesians accidentally marooned after being lost and adrift(同位语从句), it(形式主语)seems(谓语)reasonable(表语)that this feat was accomplished by deliberate colonization expeditions(主语从句)that set out fully stocked with food and domesticated plants and animals(定语从句).

　　本句的主句是it seems reasonable that… ，这里it作形式主语，真正的主语则是由that引导的名词性从句，也就是主语从句。在这个主语从句中，有that引导的定语从句，修饰前面的expeditions。另外，值得注意的是本句最前面the arguments of some that...中that引导的是同位语从句，进一步解释有些说法的具体内容。

　　参考翻译：

　　一些说法认为波利尼西亚人在迷失、漂流后偶然被困在荒无人烟的太平洋地区，从而定居下来，而与这些说法相反的则认为这个功绩是通过有意的殖民远征来实现的，他们出发时满载了食物、已培育好的植物和已驯化的动物，这样的解释似乎有道理。
