Today, we are going to continue our discussion of social insects, focusing on the Argentinean, which as you might guess is a species of ant that are natives to Argentina. We’ll consider what happened to this type of ant after some members of the species move to California from their original habitat. Ok, well, in Argentina, these Argentine ants behave like most ant species around the world. They fight other ants of the same species if those ants are from some other nests. But the Argentine ants living in California behave differently. Ants from different nests form a single large colony. Within this colony, there is little aggression among ants from different nests. And when they fight insects from outside their colony, the Argentine ants can quickly recruit a huge army from their network of nests. This of course gives them advantages over other ants’species. So then, why do Argentine ants behave differently in California than they do in Argentina? Well, using genetic testing, researchers found that all the Argentine ants in California were very similar genetically. You see, when the first Argentine ants came to California, their population must have been very small, and all the later generations of Argentine ants there must bedescended from the same few ancestors. So they are all closely related. This discovery is important, because for most social insects, membership in a colony is based on how closely related they are genetically. Now listen to the following recording and answer questions 22 to 25.
22. What aspect of Argentine ant is mainly discussed?
23. What does the professor say about Argentine ants that live in Argentina?
24. What’s the characteristic of Argentine ants in California?
25. What did genetic testing indicate about the Argentine ants in California?
选项
A、They protect Argentine ants that live in neighboring nests.
B、They gather food with Argentine ants from other nests.
C、They fight Argentine ants from other nests.
D、They generally build larger nests than other ant species do.
答案
C
解析
细节题。根据Ok,well,in Argentina,these Argentine ants behave like most ant species around the world.They fight other ants of the same species if those ants are from some other nests.可知,住在阿根廷的阿根廷蚂蚁会与来自其他蚁巢的阿根廷蚂蚁对抗。因此,正确答案为C。
