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)。
B，due to its being so genetically similar=it is similar,it是单数，自己不能相似自己，缺相似的对象。如果是复数名词可以是be similar单用，如：The brothers look very similar.
根据解释，这里有两个之前没有注意到的点：
1、similar不能直接出线，后面要跟to one another，否则不能判别相似的对象是什么
2、considers all its ［fellows］ to be ［a］ close relative，前后单复数不一致
当然我觉得这道题可以直接通过due to／because of后面跟的东西来判别
考察：
because
due to
because of
单复数
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
similar to; 且similar 需要有比较对象
the spread of this species in its native Argentina. 为什么最后未划线处用了its，这里的its不是指代Argentine ant吗，那是不是跟之前的they跟ants等复数形式不吻合了？
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。
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。
fellows和a close relative不一致可以理解成单复数搭配不一致
due to their being so genetically similar to one another 选项中这种格式是不是独立主格啊？
第n次犯同一个错误
xxx of xxx that +v. 动词的主语是第二个xxx 不是第一个
标记，注意修饰的名词单复数问题，表示相互之间相似的结构是 be similar to one another
题干its指代前文的the species ，和划线部分单复没有直接关系
标记
A due to错误 fellows搭配a relative错 limit单复数问题
B due to同上，similar裸奔 fellows搭配a relative错
C similar裸奔
D 正确
E being错误。fellows搭配a relative错
A选项：，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。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： its being so genetically similar 无比较对象，如果加上to one another可以了；主谓一致：all its fellows to be a close relative ❌
C选项： it is so genetically similar无比较对象，如果加上to one another可以了；struggles that limits???主谓一致
注意：分号前后就已经把句子结构分开了；分号后面的代词it/they对应的是后面的fellows/fellow
B:Its being so genetically similar is incorrect because there is no explicit statement of what the ant is similar to; also, the plural fellows and singular a close relative do not agree.
* "due to" is used incorrectly.
A选项：主谓一致：consider all their fellows to be a close relative❌
B选项： its being so genetically similar 无比较对象，如果加上to one another可以了；主谓一致：all its fellows to be a close relative ❌
C选项： it is so genetically similar无比较对象，如果加上to one another可以了；struggles that limits???主谓一致
E选项：all their fellows to be a close relative
