13、eks to floodwaters are victims not just of nature but of human error as well. Years of mismanagement of the vast Mississippi River ecosystem - the continuous and often inadvisable construction of levees (堤坝) and navigation (导航) channels, the paving over of wetlands, the commercial development of flo

14、od plains - have made the damage worse than it might otherwise have been. The Obama administration is now completing an inspection of the guidelines governing dams, levees and other water-related projects built with federal money.,Historically, projects had been shaped by two main factors: the Army

15、Corps of Engineers conviction that nature can be subdued by levees and dams, and its reflexive green-lighting of any flood control project that encouraged commercial or agricultural development. The new rules, Congress said, should require the Corps and other federal agencies to give equal weight to

16、 less easily measurable benefits like wildlife habitat and to “nonstructural” solutions to flood control like preserving wetlands, flood plains and other “natural systems.”,To give the Corps its due, it has performed nobly in the present emergency. Its main-stem levees have held. Its decision to blo

17、w holes in levees guarding the New Madrid floodway in Missouri clearly saved Cairo, Illinois, and other places downstream. These methods had long been part of Corps emergency plans, and they worked. The question the environmental community and many in Congress are asking is whether this would have b

18、een necessary if the river had been better managed. In populated areas, some levees were built solely to attract more development, while others closed off flood plains that could have acted as a natural safety valve.,Meanwhile, over the years, the upper Mississippi watershed has lost millions of acr

19、es of wetlands that could have served as a natural sponge for floodwaters. So-called 100-year floods seemed to be hitting the Mississippi with scary regularity - a $16 billion flood in 1993, a bad one in 2001, another in 2008, and now this one. Climate change, which some suspect of causing violent d

20、ownpours, may be part of the problem, though the connection is unclear. What is clear is that we should learn from our mistake, let nature help out where it can, and not build or farm in places where it makes no sense to do so. As the saying goes, nobody ever beats the river.,1. Why have the levees,

21、 navigation channels, etc. made the situation worse? A) Because the development of them only emphasizes economic benefits. B) Because the design and construction of them are unrealistic. C) Because they havent met the actual demand of people nearby. D) Because they are a wrong management of the ecos

22、ystem.,2. What is the Congresss suggestion to the Corps and federal agencies? A) They should pay equal attention to nature and its function. B) They should encourage commercial and agricultural development. C) They should replace their projects with “nonstructural” solutions. D) They should give wil

23、dlife habitat more attention and protection.,3. What is the authors assessment of the Corps? A) It has done nothing useful in flood control. B) It has caused great damage to ecosystem. C) It has played an important role in emergency. D) It has justified its projects effectively.,4. What function are

25、 the main cause of the violent downpours and floods. C) It has been proved to be related to violent downpours and floods. D) It may be part of the reason causing violent downpours and floods.,阅读理解第2篇,School shootings are in the news again. An Ohio teenager opened fire on five classmates, killing thr

26、ee students and injuring two other. In Seattle, the 9-year-old boy brought a gun to school and seriously injured a classmate when it was accidentally discharged in his backpack. Children are injured and murdered every day, but school violence carries a symbolic effect because we like to think of sch

27、ools as safe havens from the hardness of adult life. Its horrifying to think that the institutions could be a place of injury or even death.,Politicians and taxpayers like to hold teachers responsible for their students failures for the belief that a childs fate rests largely in the hands of the tea

28、cher in whose care he or she spends approximately 1,000 hours per year. Yet the remaining 7,760 hours are on someone elses watch: the parents-children spend on average only about 11% of their childhood lives in school.,But we rarely talk honestly about what can happen during the other eight-ninths o

29、f their waking and even sleeping hours. Children arrive at school poorly nourished and too fatigued to work. They spend too much time on television and too little on exercise.

30、hem on innocent people, including, sometimes, themselves.,Where are the parents?

Nationally, 90% of fatal firearm shootings of children aging 0 to 15 occur in the home.,We are not saying

32、that every time a kid does something wrong, a parent must be held responsible or be blamed. But a system that focuses its attention for kids failings everywhere but at home is equally blind. We hold hosts liable when a driver drinks at their home and kills someone while driving drunk. Having an unlo

33、cked, loaded gun in a home with a child under 16 should be a crime.,61. Why is it horrifying to think that schools could be a place of injury or even death? A)Because some children bring weapons to school. B)Because children may get injured at school. C)Because people thought school is a safe place. D)Because school violence carries a chain reaction.,62. People tend to blame teachers for their students failure because _. A)students spend 11% of their childhood
