请问一下楼主 土著社区是寂静里哪一篇啊？是那个墨西哥研究吗？是不是下面这篇？？谢谢谢谢！

Two divergent definitions have dominated sociologists'
discussions of the nature of ethnicity. The first emphasizes
the primordial and unchanging character of ethnicity. In
Line this view, people have an essential need for belonging that
(5) is satisfied by membership in groups based on shared
ancestry and culture. A different conception of ethnicity
de-emphasizes the cultural component and defines ethnic
groups as interest groups. In this view, ethnicity serves as
a way of mobilizing a certain population behind issues
(10) relating to its economic position. While both of these
definitions are useful, neither fully captures the dynamic
and changing aspects of ethnicity in the United States.
Rather, ethnicity is more satisfactorily conceived of as a
process in which preexisting communal bonds and common
(15) cultural attributes are adapted for instrumental purposes
according to changing real-life situations.
One example of this process is the rise of participation
by Native American people in the broader United States
political system since the Civil Rights movement of the
(20) 1960's. Besides leading Native Americans to participate
more actively in politics (the number of Native American
legislative officeholders more than doubled), this movement
also evoked increased interest in tribal history and tradi-
tional culture. Cultural and instrumental components of
(25) ethnicity are not mutually exclusive, but rather reinforce
one another.
The Civil Rights movement also brought changes in the
uses to which ethnicity was put by Mexican American
people. In the 1960's, Mexican Americans formed
(30) community-based political groups that emphasized ancestral
heritage as a way of mobilizing constituents. Such emerg-
ing issues as immigration and voting rights gave Mexican
American advocacy groups the means by which to promote
ethnic solidarity. Like European ethnic groups in the
(35) nineteenth-century United States, late-twentieth-century
Mexican American leaders combined ethnic with contem-
porary civic symbols. In 1968 Henry Cisneros, then mayor
of San Antonio, Texas, cited Mexican leader Benito Juarez
as a model for Mexican Americans in their fight for con-
(40) temporary civil rights. And every year, Mexican Americans
celebrate Cinco de Mayo as fervently as many Irish
American people embrace St. Patrick's Day (both are major
holidays in the countries of origin), with both holidays
having been reinvented in the context of the United States
(45) and linked to ideals, symbols, and heroes of the United
States.

謝謝樓主 哈哈
如果有想起邏輯再蠻煩補一下

请问最后V考了多少分啊？同觉得SC基本没有split，5个选项都不一样，直接导致做SC时间过长，pace崩溃掉了。 ...

我v太惨了…28………我也pace乱了。差点没做完……最后后面都乱点了

Two diverge ...

emmmm应该是改过的。因为我看到的那篇侧重于对比一个叫D啥啥的人他的发现和前人的发现有啥不同。

好的！！！我一定会努力想一想！！！

HelloMrMilk

想问一下楼主第一个数学题，有没有x不等于y的条件呀， 如果没有是不是条件二也不对 （比如3/3 = 5/5）

应该是没说等不等的问题的。不过我觉得这个不影响做题呀。题目要求咱们判断那两个数相比有没有可能相等或者不等。即使包含了你说的那个条件，也是可能等可能不等。但是题目给的B的条件应该是两个肯定不会等。就是选B的话得出的答案是唯一的。就够了？

我的意思是如果题里面没说x和y不等，那条件二感觉是不是不充分， 他说x is not divisible by t, 那就是x和t互质，这就存在两种情况
如果x 不等于 y, 那就是你说的 r/t 不等于 y/x
但是如果x 可以等于 y. 在条件二里面，r/t 是有可能= y/x的 （比如3/3 = 5/5，这个等式满足了条件二说xt互质）
所以如果题目没给x不等于y的条件，在题目给的条件二里那两个式子是有可能等也有可能不等的，所以是不是应该是不充分
同理，就算把条件一考虑进来也是可能等可能不等 （如3/3 = 8/8）
所以这样看是不是应该选E

我觉得你说的也有道理。你是在这一期里面考吗？要是的话上考场的时候看看清楚，不过你说的这个我之前还真没考虑过，我看917里面有的回忆的给了不相等的条件，但我真是想不起来了抱歉！！

恭喜lz数学51！！！！有一个第七题想找楼主确认一下！！
7S:n= r^a*s^b，问 n 的算数平方根是不是整数?
条件 1:a + b 是偶数
条件 2:ab 是偶数（啊我翻的917.。真的是一毛一样呢！）
这题我也看了917里面选的C，但是如果r是2，a是负2，s是1，b是2的话，ab也满足条件一和条件二，但是n等于二分之一欸~~所以题目里有没有排除a和b是负数的条件呀？
