红火蚁蔓延带来的威胁
Australia's ecosystems are in danger because of the invasion (入侵) of the red fire ant, which is considered one of the most harmful invasive species in the world.
The small ant is native to South America, but has spread to many countries in the world, causing huge harm to agriculture and ecosystems. It not only destroys crops and farms but also kills large numbers of native insects, and other animals. The ant's painful sting (蜇伤) can cause serious allergies (过敏) in humans, which might even lead to death. The Minister for Agriculture calls these ants "super pests (害虫)" because they do great harm to society, the economy, and the environment.
Red fire ants were first found in Australia in 2001. They have largely been contained within the state of Queensland since then. However, Australia's Invasive Species Council (ISC) says the ants are spreading across the country because of floodwaters. They are holding onto each other to form "rafts(木筏)" on the water. The ISC said, "Red fire ants are more active before or after rainfall and can form large floating rafts, which move with the flow of the water to find places to stand in new areas." It warned that the red fire ants would reach "every corner of Australia" if the current (目前的) outbreak was not under control.

二、【主旨大意】本文介绍了红火蚁原分布于南美洲，现已蔓延至许多个国家。由于洪水泛滥，这种蚂蚁正在向整个澳大利亚蔓延，对社会、经济和环境构成严重威胁。
1. A【点拨】词义猜测题。由第一段可知，这种蚂蚁原产于南美洲，所以对于其他地方来说，红火蚁是入侵物种，故画线单词的意思是“侵入的”。故选A。
2. A【点拨】细节理解题。由第二段可知，红火蚁会破坏庄稼和农场，会杀死大量的本土昆虫和其他动物。被这种蚂蚁蜇伤的刺痛处会导致严重的过敏，甚至可能导致死亡。故①②③所述与此相符。文中并未提到红火蚁会污染空气，故④不正确。故选A。
3. B【点拨】细节理解题。由第三段第三句可知，红火蚁通过洪水蔓延到澳大利亚的其他地区。故选B。
4. C【点拨】写作意图题。文中提到的声明的意思是“红火蚁在降雨前后更活跃，它们可以形成大型浮筏，随着水流移动，在新的地区建立立足”。由此可知，红火蚁通过洪水迅速蔓延。故选C。
