2023届北京市部分区高三二模英语解析版试题分类汇编 七选五 2023届北京市海淀区高三下学期二模英语试题 第二节(共5小题;每小题2分,共10分) 根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项,并在答题卡上将该项 涂黑。选项中有两项为多余选项。 Humans have long tried to conquer water. We’ve straightened once-winding rivers for shipping purposes. We’ve constructed levees (防洪堤) along rivers and lakes to protect people from flooding—We’ve erected entire cities on drained and filled-in wetlands. We’ve built dams on rivers to store water for later use. _35_ But it’s not, argues environmental journalist Erica Gies,author of Water Always Wins. Levees, which narrow channels causing water to flow higher and faster, nearly always break. Cities on former wetlands flood regularly—often disastrously. Dams starve downstream areas of sediment (沉积物) needed to protect coasts against rising seas. Straightened streams move faster than winding ones, giving water less time to flow downward. And they wash away riverbed ecosystems. In addition to laying out this damage done by supposed water control, Gies takes readers on a hopeful global tour of solutions to these problems. Along the way, she introduces “water detectives” —scientists,engineers,urban planners, and many others. _36_ These water detectives have found ways to give the slippery substance the time and space it needs to flow slowly underground. Around Seattle’s Thornton Creek, for instance, reclaimed land now allows for regular flooding, which has renewed riverbed habitat and created an urban oasis. In California’s Central Valley, scientists want to find ways to move unpolluted storm water into subsurface valleys that make ideal aquifers (含水层). _37_ While some people are exploring new ways to manage water, others are leaning on ancient knowledge. Researchers in Peru are now studying old-style methods of water storage, which don’t require dams, in hopes of ensuring a steady flow of water to Lima—Peru’s populous capital that’s periodically affected by water shortage. _38_ “Decision makers come from a culture of concrete,” Gies writes, “in
