2．The Pacific island nation of Nauru used to be a beautiful place．Now it is an ecological disaster area．Nauru's heartbreaking story could have one good consequence-other countries might learn from its mistakes．
For thousands of years，Polynesian people lived the remote island of Nauru，far from western civilization．The first European to arrive was John Fearn in 1798．He was the British captain of the Hunter，a whaling ship．He called the island Pleasant Island．
However，because it was very remote，Nauru had little communication with Europeans at first．The whaling ships and other traders began to visit，bringing guns and alcohol．These elements destroyed the social balance of the twelve family groups on the island．A ten-year civil war started，which reduced the population from 1，400to 900．
Nauru's real troubles began in 1899when a British mining company discovered phosphate （磷酸鹽）on the island．In fact，it found that the island of Nauru was nearly all phosphate，which a very important fertilizer for farming．The company began mining the phosphate．
A phosphate mine is not a hole in the ground； it is a strip mine．When a company strip-mines，it removes the top layer of soil．Then it takes away the material it wants．Strip mining totally destroys the land．Gradually，the lovely island of Nauru started to look like the moon．
In 1968，Nauru became one of the richest countries in the world．Every year the government received millions and millions of dollars for its phosphate．
Unfortunately，the leaders invested the money unwisely and lost millions of dollars．In addition，they used millions more dollars for personal expenses．Soon people realized that they had a terrible problem-their phosphate was running out．Ninety percent of their island was destroyed and they had nothing．By 2000，Nauru was financially ruined．Experts say that it would take approximately $433，600，000and more than 20years to repair the island．This will probably never happen．

分析 本文主要講述太平洋上的島國Nauru過度使用自己的資源導致最后資源枯竭，國家陷入破產(chǎn)的實例，以警告我們在發(fā)展過程中要注意科學發(fā)展．
解答 28．B．主旨大意題．本文通過太平洋上的島國Nauru過度使用自己的資源導致最后資源枯竭，國家陷入破產(chǎn)的實例，以警告我們在發(fā)展過程中要注意科學發(fā)展，故B正確．
29．B．細節(jié)理解題．根據(jù)第四段1，2哈根Nauru's real troubles began in 1899 when a British mining company discovered phosphate（磷酸鹽）on the island．說明這個島國的命運發(fā)生改變就是因為發(fā)現(xiàn)了phosphate（磷酸鹽）的礦產(chǎn)，故B正確．
30．A．細節(jié)理解題．根據(jù)文章最后一段第1行Unfortunately，the leaders invested the money unwisely and lost millions of dollars說明領導人錯誤投資也是一個主要的原因，故A正確．
31．A．細節(jié)理解題．根據(jù)文章最后三行．By 2000，Nauru was financially ruined．Experts say that it would take approximately$433，600，000 and more than 20 years to repair the island．This will probably never happen．說明這個國家所受的破壞要想恢復要耗費很多的資金，已經(jīng)很難再恢復到以前了，故A正確．
點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
