7．One picture in the Wonder Book of knowledge I had as a little boy showed a man reading a book while floating in the Dead Sea．What a miracle!How would it feel to lie back in water so thick with salt that it was impossible to sink？
Fed by the Jordan River and smaller streams，the Dead Sea is the lowest point on the earth's surface，and its water is ten times saltier than the Mediterranean．With evaporation its only outlet，salt and other minerals become super-concentrated．
Earlier this year，I drove down the long，steep hill to realize my dream．The shoreline was a broad area of bare salt-mud，but the water edge was far out of sight．Had somebody pulled the Dead Sea's plug？I wondered．Eli Dior，an Israeli official，explained the problem："The Dead Sea is drying up．Every year，the surface drops about one meter，and as the water level falls，shadow areas are left high and dry．"
Over the last half-century，the five neighboring countries have collectively diverted nearly all the water flowing into the Dead Sea to meet human and agriculture needs．Result：the Dead Sea is being emptied．
With population in the region set to double at least in the next 50years，there is little hope of restoring the water being diverted for human consumption．No country has a drop to spare for the Dead Sea，where they know it will just evaporate．To dream of opening the dams and restoring natural balance is plainly unrealistic．
Yet one ambitious high-tech dream may turn out to be not only the salvation of the Dead Sea but also a ticket to peace around its shores．The"Red-Dead"is a proposed $5billion project to bring sea water some 240kilometers by pipeline and canal from the Red Sea to the Dead Sea．The Red-Dead may be the only solution，but even if the project is carried out successfully，the Dead Sea will be 10to 20meters lower than now and two thirds of its current size．
Whatever the future holds，the Dead Sea's magical mix of sun，mud，sea and salt will surely survive．Many might complain that the Dead Sea is half empty-but for me the Dead sea will always be half full．

76．Which of the following is right according to the passage？A
A．With no outlet to any ocean，the Dead Sea has become by evaporation the saltiest on earth．
B．Though burdened with the growing population，the neighboring countries haven't cut off the sources of the Dead Sea．
C．All the countries in the area will consider diverting less water from the Jordan River．
D．The Red-Dead Project has not only brought water to the Dead Sea，but peace to the area as well．

分析 本文属于说明文阅读，作者通过这篇文章告诉我们如今死海中的水正在不断的被蒸发，因此死海也在慢慢干涸，很多国家在想办法将海水汇入死海，而在作者心中死海是永远半满的，是不会干涸的．
解答 74．C 主旨大意题，通读全文可知本文主要向我们讲述了如今死海正在慢慢干涸的事实，故选C．
75．A 细节理解题，根据第三段The Dead Sea is drying up．Every year，the surface drops about one meter，and as the water level falls，shadow areas are left high and dry．"可知死海正在慢慢干涸的原因是因为它的水位不断下降，流入死海的水越来越少，故选A．
76．A 细节理解题，根据第二段With evaporation its only outlet，salt and other minerals become super-concentrated．可知死海没有出水口，蒸发是唯一的出口，因此死海中的盐类和矿物质很多，故选A．
77．D 推理判断题，根据最后一段Many might complain that the Dead Sea is half empty-but for me the Dead sea will always be half full．可知很多人可能会抱怨死海已经快空了，但是对作者来说死海永远是半满的，因此作者认为死海是不会干涸的，故选D．
点评 考查学生的细节理解和推理判断能力．做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确选择．在做推理判断题时不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
