参考解析
解析：
该段录音主要讲述未来的飞机可能与the Wrights’ pioneering effort有更大的不同，，人们现在只能对到底有多么不同进行猜测，而题干描述的“未来的飞机可能会采用与the Wrights’ pioneering effort从根本上不同的飞行原理”过于绝对。
【录音原文】
Tomorrow’s air craft are likely to be still more marvelous, and perhaps even more different than today’s from the Wrights’ pioneering effort. Predicting how different requires guess work, an open mind and even a dollop of science fiction.

Air pollutionPeople and air pollution are often in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major kind of air pollution is the gas from cars. Statistics(统计资料) show that 93 percent of all auto trips are within cities.Another major kind of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the county.On the average, we throw away more rubbish than the year before. The burning of rubbish makes air pollution even worse. Many major industries are also responsible for the dirty air in the around cities. The fumes(烟)from iron, steel, chemical, and petrol production add particles(微粒)to the air.The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode(腐蚀). In some of the larger cities, these fumes endanger the lives of human beings by contributing to lung diseases and causing early death.26. The key point of the passage is that().A. the cause of air pollution is peopleB. the causes and the effects of air pollution are both found in citiesC. the effects of air pollution range from headaches to death27. What is the purpose of this passage?A. to persuade people to stop polluting the air().B. to tell the causes of air pollutionC. to tell why cities are bad places to live28. Why is air pollution more grave in the city than in the country?().A. Because there are larger populations in cities.B. Because the air in the city is dirty.C. Because there are much more gas fumes from cars and burning of coal and oil for energy in the city than in the country.29. The fumes from coal and oil may cause metal().A. to corrodeB. to twistC. to turn black30. In larger cities, the fumes from coal and oil may contribute to().A. heart diseaseB. loss of clear visionC. lung diseases

第二篇Archive Gallery : The Best of Bionics（仿生学）Humans might be the most highly-evolved species on the planet,but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the way catsdo. Imagine leaping from tree to tree like a monkey. Giraffes（长颈鹿）,which are otherwise calm and good- natured,sleep only 4.6 hours a day.We realized a long , long time ago that nature provides the best blueprint（蓝图）for invention. We ' ve borrowed canals from beavers（河狸）and reflectors from cat's eyes. Although the words"bionics"became popular only after the l960s,history shows that nature has always provided ideas on solving everyday prob- lems. Our archives（档案）don't go back to the time of Leonardo da Vinci and his bird-like flying machines,but we can take you to the late 19th century,where we applied those same principles for building our first practical airplanes.To prepare for their flight at Kitty Hawk,the Wright brothers studied the movements of pigeons to fingureout how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature.One of Orville Wright's pupils caught and stuffed seagulls to examine their wingspan.Meanwhile,two French inventors examined spinning sycamore（美 国梧桐）seeds in an effort to apply those same motions , reversed , to a helicopter.Some examples are more obvious than others.The outside of the airplane designed by the WrightDrotliers looks like a minimalistic（简单抽象艺术）structure.

A cool mass of air heads toward the United States from the upper regions of Canada and Alaska this week according to the National Weather Service.
According to the NWS a mass of cold air will drop from the Arctic regions to Canada and then the upper Midwest next week.
Temperatures across the Midwest will drop into the 60s and 70s-a sharp difference from the 80 degree and 90 degree temperatures from recent weeks. And the relatively cooler air may be felt as far East as New York and Washington
The cool breezes may be a welcome relief this time around but remember the last few times we got hit with Arctic air？
Temperatures in cities including Chicago Cleveland New York and Louisville fell into single-digit and negative territory for long stretches during the harsh winter months of early 2014. But we’re sure you remember
