invasive species的文章里出现的第二类昆虫：Red imported fire ant.

　　Red imported fire ant 火蚁

　　本地栖息地：South America

　　运送模式：Soil in ships

　　侵略范围：Southern United States (1930s, mainly 1950s)

　　也会出现在：Australia, Taiwan, China, and the Philippines

特点01.进攻性体现在咬人

　　aggressive with a painful bite

　　[aggressive: An aggressive person or animal has a quality of anger and determination that makes them ready to attack other people.]

　　02建筑材料随着土壤运送到美国

　　construction materials delivered to the U.S along with soil, a comfortable way to travel

　　[deliver: If you deliver something somewhere, you take it there.]

　　03.数量增长很快且转移它们的殖民地

　　[colonies: a group of animals of the same type living together; tremendous: We use tremendous to emphasize how strong a feeling or quality is, or how large an amount is.]

　　04.降雨量多的季节，会随着积水飘进房屋、汽车和楼房，并给人带来伤害

　　heavy rain periods, float for months, move into homes , autos, and buildings, and attack people

　　火蚁给人带来的危害，从它的特性我们可以深刻感受到。但是这个危害的罪魁祸首，还是人类自己。Construction material的运输来源于人类的世界贸易、经济需求和交通发展。正如我们本期文章的丢篇invasive species提到的，要从辩证的思维看问题。Global trade可以给人类带来经济的快速发展，但是同时也会带来灾害性的影响。至于如何减弱或者消除这种现象，目前没有两全其美的办法。只能通过科技的发展和人类保护环境意识的提高，来尽量避免这些损失。
