In California, a lack of genetic variation in the Argentine ant has allowed the species to spread widely; due to their being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits the spread of this species in its native Argentina.
due to their being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits
due to its being so genetically similar the ant considers all its fellows to be a close relative and thus does not engage in the kind of fierce intercolony struggles that limit
because it is so genetically similar, the ant considers all its fellows to be close relatives and thus does not engage in the kind of fierce intercolony struggles that limits
because they are so genetically similar to one another, the ants consider all their fellows to be close relatives and thus do not engage in the kind of fierce intercolony struggles that limit
because of being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits
题目分析：
本题虽然划线部分比较长，但是难度不算大，考点较为单一。
选项分析：
A选项：最后的定语从句that limits the spread of this species in its native Argentina需改为that limit the spread of this species in its native Argentina。定语从句会就近修饰一个单复数搭配的名词。在逻辑上，限制传播的是复数名词fierce intercolony struggles，而不是单数名词kind。 kind是种类的意思，种类不会限制传播。另外， all their fellows和 a close relative不搭配。不能是所有它们的伙伴是一个近亲。
B选项：fellows和a close relative不搭配错误同(A)；similar在本选项中身后缺少one another，这会使得我们不知道similar的对象是谁。
C选项：similar身后缺少one another错误同(B)。
D选项：Correct. 本选项在语法和逻辑上均是正确的。
E选项：fellows和a close relative不搭配错误同(A)。
因为due to 的用法是只能修饰主句的名词主语，直接就可以排除AB 同时定语从句limits排除CE 直接选D
这道题，如果能够先发现limit存在主谓一致的问题，可以快速定位，只从B和D里选。会节省很多时间。
1.the ant considers all its fellows to be a close relative 蚂蚁的伙伴是一个亲戚
the ants consider all their fellows to be close relatives 蚂蚁的伙伴是亲戚
2.similar 后面要接对象，be similar to...
3.不要被后文in its native Argentina所影响，【ant很明显是一个可以加复数的名词而不是集体名词】，这里its指代this species
在逻辑上，限制传播的是复数名词fierce intercolony struggles，而不是单数名词kind。 kind是种类的意思，种类不会限制传播。
未划线的its指代this species。
limit的主语是struggles，要用复数形式，排除ACE，剩下B和D。
B里边similar后面没有跟to sth.，排除。
D 可以用They
similar在本选项中身后缺少one another
fellows和a close relative不搭配错误
判断从句的谓语动词单复数——找先行词， 先行词复数就不能用单三。
similar后要有相似对象
错选：c。b 正选：d
b：fellows /relative 单复数问题
c similar后缺少相似的对象 b也有这个问题
以为考察点在不同的代词 their, its ,they是否指代清楚。。。
'I don't like the kind of animals that live here.' and 'The kind of animal that lives...'. You'll see that the 'that' refers to the animal or animals, not the 'kind'. --From MGMAT
the kind of X that ... that后面的谓语是跟随X，而不是the kind
similar后面一顶要跟另一个东西，不然和啥相似嘛
B：similar在本选项中身后缺少one another，这会使得我们不知道similar的对象是谁。
similar后面要跟对象
similar固定搭配 be similar to xxx
similar to one another 且 the kind of fierce intercolony struggles that limit 定语从句就近修饰 是struggles限制 不是kind 因此用谓语复数
我想知道句子最后的未划线部分有个its 前面怎么还能选有 they的选项啊，这样单复数不是冲突了吗！
我也想问！！！
同学我现在好像想明白了 这个its应该跟的是前面的 this species，所以划线部分用they的话没关系 你jio得呢！
我感觉本身species就是单复数同行的…而且全文一直说的就是这个species...应该全文单复数一致比较好吧…既然前面都用了they复数…后面说this species…就应该指species是复数来用的…所以即使指代this species也应该用复数呀
但是你想如果这里的species是复数的话 前面就不能跟this啦
嗯…对奥～

主要看后面的从句修饰的是哪一个部分！！！

单复数
struggles that limit
similar后需要有对象：B similar在本选项中身后缺少one another，这会使得我们不知道similar的对象是谁。
