11．Burmese pythons （緬甸蟒蛇） are some of the biggest snakes in the world and also one of the biggest problems in Florida's wetlands．So state officials have asked hunters to lend a hand．
The pythons are originally from Asia．Brought to the US as pets or zoo animals，some were released or broke free into the wild and found Florida's warm weather to be perfect for a new settlement．It is estimated that tens of thousands now live in the everglades and the state's marshy wetlands．
These supersize snakes are invasive species．"The problem is with animals，"says Carli Segelson，spokesperson for the Florida Fish and Wildlife Conservation Commission．"The pythons eat native birds，reptiles，and small mammals，many of which are threatened species．"Since the python moved in，several native species，such as bobcats and rabbits，have largely disappeared from Florida's wetlands．So the Florida government has invited hunters to assist in solving this severe environmental problem．People will be allowed to hunt pythons around their breeding grounds for one month，starting on January 12．
Officials are even offering cash prizes to whoever kills the most pythons and to whoever kills the longest Burmese pythons．They are hoping the contest will significantly reduce the population ofthis dangerous invader．
"Our goal is to help get rid of the pythons from the wild，educate the public about the snakes'impact on the Florida ecosystem，and inform them of what impacts non-native pets can have if allowed into the wild．"Segelson said．Experts say it's unlikely the snakes will ever be removed from the wild in Florida．But they hope to bring the python problem under control and prevent the snakes from doing more harm．

分析 本文主要介紹了美國的佛羅里達州政府讓獵人們獵殺外來物種緬甸巨蟒的情況，因為這些巨蟒造成本地物種瀕臨滅絕．
解答 28．A 細節(jié)理解題．根據(jù)第二段提到It is estimated that tens of thousands now live in the everglades and the state's marshy wetlands．據(jù)估計有成千上萬的蛇生活在沼澤和濕地，故可知選A項．
29．A 句意猜測．根據(jù)第三段提到The pythons eat native birds，reptiles，and small mammals，many of which are threatened species這種蛇吃本地的鳥，爬行動物及小型哺乳動物，危及這些物種的存在，故選A項．
30．D 詞意猜測．根據(jù)倒數(shù)第二段提到Officials are even offering cash prizes to whoever kills the most pythons and to whoever kills the longest Burmese pythons官方甚至提供現(xiàn)金來獎勵那些殺死最多和最長緬甸蟒蛇的人，可知危險的入侵者指的是緬甸蟒蛇，故選D項．
31．B 推斷題．根據(jù)最后一段提到Our goal is to help get rid of the pythons from the wild，educate the public about the snakes'impact on the Florida ecosystem，and inform them of what impacts non-native pets can have if allowed into the wild，我們的目標是幫助擺脫這些蟒蛇，教育公眾蛇對于佛羅里達的生態(tài)的影響，告知他們非本地寵物被放生野外的影響，故選B項．
點評 本文是一個科教類閱讀理解，題目涉及多道細節(jié)理解題，做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進行仔細分析，結(jié)合選項選出正確答案．推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案，切忌胡亂猜測，一定要做到有理有據(jù)．
