GWD-24套-41

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.

A.    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

B.     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

C.    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

D.    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

E.     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

答案是C。为什么D不对？ 而且C中变成it is so 的句型是不是有加强语气的作用？原文好像没那么强烈的语气呀。

谢谢大家。

"the kind of colongy struggles" 表一类名词概念，是单数（强调其共性），大全里有一道类似的题：

正确答案代入后为：In the most common procedure for harvesting forage crops such as alfalfa, as much as 20 percent of the leaf and small-stem material, the most nutritious parts（注意此为同位语为复数，对应the leaf and small-stem material这两部分）of the plant, shatters and falls （对应20% of..整个短语）to the ground.

前面不是一个it is 么..

D是 they are.

原文的so genetically similar的确有强调语气的作用,in my opinion.

D中也有so啊.

the point is, C,D都用了so....that 句型哦.

对的，C 和D都用了 so ...that...这个不是问题所在；关键在于你说的so..that..是不是也是能够加强语气的。好像一般不能够把原文改成it is形式，太强烈，但这个我不确信。

另外D的 they are。 因为之前的所有n.里面只有一个复数species,不会引起歧义吧，只能修饰这个species。这个和后面的逻辑也不矛盾啊。D错在哪里呢。。

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.
   

species这里是单数。

species这里是单数。

未划线句子中的its表明D不对.

the spread of this species in its native Argentina

明白了明白了。多谢MM。

但C为什么用LIMITES不用LIMIT呢？

支持选c

d没道理
