It is generally agreed that Native这句话的语法分析
亲啊：你提供的是不完全的句子.
完全的句子来自选修7 Module 5 Ethnic Culture
Native Americans and Australian Aborigines
Among the most well-known ethnic minorities of the English-speaking world are the Native Americans of North America,and the Australian Aborigines .
It is generally agreed that Native Americans came across from Asia ,somewhere between 12,000 and 25,000 years ago .
语法是一个比较大的范畴.你需要的是句法分析吧?
it is generally agreed that-从句可以说是一个句型.
it是形式主语.谓语是被动语态.真正的主语是由that引导的主语从句.
是People generally agree that-从句的被动语态.一般译作：人们普遍同意（认为）.
下面对这个主语从句进行句法分析：
主语：Native Amercians 土著美洲人
谓语 came across from the Asia 是从亚洲这边过来的（横过白令峡）
这里的somewhere有两个理
1.表示地点.意为“在某个示方”,作地点状语,但主句中是动态动词(came across from ...),所以这个理解是不通.where不含有介词from,所以不能理解成“从某个地点”
2.表示时间轴上的某点(比如+这一点） 25,000 years ago----------+---------12,000(years ago)-------------------------------------------> Time (now) ,在句子中是作时间状语的.
意为：在二万五千年前和一万二千年前之间的某个时期
