In California, a lack of genetic variation in the Argentine ant has allowed the species to spread widely; 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 the spread of this species in its native Argentina.

看前面的species以为是应该用复数谓语动词，但是看到后面的its才发现应该用单数的，并且species是个集合概念在这里。但要注意，species也可以作为复数名词存在的，因此还是要根据前后句判断。别看了前句就忘了看后句，对于这种课单可复的名词。

that从句修饰the kind of而不是struggles，所以应该用单数

“its native Argentina" 注意its，前面要用单数

用they are 而不是 it is 解释：It's nonsense to say that just one thing is "similar". If you don't see why, just make up a couple of examples. This bird is similar. (Huh?) These two birds are similar. (Makes sense.) BY RON 未划线部分的 its 解释：its refers back to species, so having a singular or plural ant/ants does not matter in this instance. You can have a group of things that is then later referred to in the sentence as a single entity

我是这样做的：因为第一行ant是单数，且最后一行用的是its，所以划线部分的ant用单数，

its native Argentina,可以看出前面用单数， the ant，its

ants是复数，但是its refer back的又不是ants，是之前的species，species即可做单数也可以做复数（和fish一样）。

it指代的是the Argentine ant这个物种吧，还有划线外可以找到提示

划线外的in its native... 若 they指代species, 种类很基因相似其他种类有点奇怪 they are similar to one another有没有问题? that limits为什么是单数?

我擦，划线外居然有its，我死了，再见，大家
