5.In North America,the Colorado(科罗拉多)River is a legend.It has sustained generations of people and many generations of wildlife.Once free,the Colorado now has many dams along its 1,450miles.Its life-giving water is divided up among seven U.S.states according to several agreements,which has caused the heaviest hit on the eco-balance of the river as no region would lose advantages compared with neighbours in the use of the river,thus inappropriate use was well expected.The Colorado once supported a vast delta(三角洲)where it met the Gulf of California.Today the lush plantations are just memories,displaced by invasive species capable of surviving in soils poisoned by salt.The drying of the delta has huge effect on the local people.As many as 5,000people were living in the delta 400years ago.Today,about 300remain.There is a delta culture at risk of extinction,partly owing to outside job opportunities and marital mobility.However,the worsening living environment caused partly by horrible grab of the waters of the Colorado River has beaten all the other reasons.
It's easy to blame farmers along the Colorado for drawing waters from its channel to water their crops or quench the thirst of their cows.They are immediate consumers of water from the Colorado,but the truth is that we,ordinary American consumers,are all at least partially responsible.Many of us have bought products that come from the region,whether in the form of paper,hamburgers,or electronics.We live in an increasingly connected world,in which we take up"virtual water"in the form of products and even services.In the U.S.,we use twice as much water per person as the global average.
Though it may seem to work in the short term,we can barely fix the Colorado by piping water from another place.But change is urgent.Use a water calculator to see how much water you use every day.Pay special attention to saving every drop of water hidden in your diet and wardrobe.And keep away from life styles that might waste water.In all,try to form a water-efficient habit.
Besides,technology improvement will also be explored to make change happen in the rescue efforts.These technologies include methods to increase farming efficiency,and ways to replace invasive,water-sucking plants with native species.
Anyway,it's time we humans rose up and repaid the mother river that has long been nurturing us.

分析 本文讲述了在北美,Colorado(科罗拉多)River 过去是一条哺育两岸生命的母亲河,但是现在却遭到严重破坏,以此号召人类去保护它.
解答 78.Colorado water is divided up among seven U.S.states.细节理解题.第一段Its life-giving water is divided up among seven U.S.states according to several agreements,which has caused the heaviest hit on the eco-balance of the river 这句话提炼出,这条河被美国七个州瓜分,造成了严重的生态危机.这是导致河流遭破坏的主要原因.
79.the worsening living environment 细节题.第二段提到delta culture 濒临灭绝的几个原因,如partly owing to outside job opportunities and marital mobility,以及the worsening living environment,紧接着提及这个原因has beaten all the other reasons.由此可见,主要原因在于此.
80.Farmers along the Colorado and ordinary American consumers.概括题.第三段开头farmers along the Colorado for drawing waters from its channel to water their crops or quench the thirst of their cows提到沿岸的农民用水来灌溉庄家牲畜,是造成Colorado水短缺的原因之一;ordinary American consumers普通的美国消费者也是原因.故总结为两者.
81.form a water-efficient habit and improve technology 概括题,第四段提到如何解决水短缺的问题,比如计算每天用水量,节约每滴水,概括起来就是形成高效的用水习惯;最后一段还提到运用科技来改善.
