Major water works that draw water from the Huangpu will need more treatment facilities to improve the color,texture(結(jié)構(gòu)),ammonia(氨)and nitrogen(氮) content before 2010.

　　These treatment facilities are expected to cost 4 billion yuan,something that could affect the price of water,according to Chen Yin,SWA's deputy director general.

　　Chen said that replacing water pipes was also a key project.The city's aged pipes are mostly to blame for the bad water quality.

　　The SWA has started the water facilities renovation(整修) work,including the more than 14,000 kilometers of indoor piping,107,000 tanks on top of the buildings,and more than 6,000 underground facilities.

　　World Water Day came on March 22,and this year's theme is“water for the future”.Beijing is also drawing up plans during China's Water Week,which runs until March 28.

　　By 2008,the water for the Olympic Games is to above World Health Organiation standards.And,the people of Beijing will be able to drink their tap water as well.

　　參考答案：

　　Passage

　　1.細(xì)節(jié)題。潛在的水危機(jī)的真正原因是什么?四個選項(xiàng)分別是：選項(xiàng)A世界上的水只有一半可以利用;選項(xiàng)D世界人口增長越來越快;選項(xiàng)C世界水源的一半已被污染;選項(xiàng)人類對水源還沒有足夠的重視。相關(guān)信息在第一段最后一句：因世界人口在未來的50年里翻一番，所以許多專家認(rèn)為我們正處于大范圍水危機(jī)的邊緣。接著，第二段前兩句語氣一轉(zhuǎn)說：但是結(jié)果未必如此。如果我們現(xiàn)在開始珍視水，水短缺也許不會令世界不安。就像20世紀(jì)70年代石油危機(jī)后開始珍視石油一樣，今天我們必須以一種新的經(jīng)濟(jì)視角來看待水。根上面的陳述，答案為D。��

　　2.推斷題。正如文章所述，水問題：選項(xiàng)A在世界的某些地方已是嚴(yán)重的問題;選項(xiàng)B被這個領(lǐng)域的一些專家夸大;選項(xiàng)C對建造水庫的技術(shù)提出了質(zhì)疑;選項(xiàng)D被不同級別的政府部門低估。根據(jù)文章首段第一句和第二句：雖然人類用水量還不到世界現(xiàn)有水的一半，但是一些地區(qū)的饑荒和困境卻是缺水和干旱造成的。既然饑荒和困境因缺水和干旱而起，顯然水問題已是一個不容忽視的問題。答案為A。��
