3.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

    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

    第三篇

    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 cats
    do. 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 1960s,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 figure
    out 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’、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 Wright
    brothers looks like a minimalistic(简单抽象艺术)structure. On the other hand , Barney Connett ' s fish
    submarine(潜水艇)actually looks like a fish.
    Some bio-inspired concepts have yet to be invented.In the 1960s,the US Army commissioned several
    university professors to conduct research on the motor skills of animals in hope of applying those same abili-
    ties to tanks. Tanks that run like horses or jump like grasshoppers(蚂昨)一sounds shocking,doesn't it?
    But imagine how life would change if we could achieve that.

    What does the writer want to tell in the passage?
    A:Some animals possess unique skills.
    B:Many inventions get ideas from nature.
    C:People should protect nature.
    D:Bionics is far from perfect.

    答案:D
    解析:
    文章第一段第一句中提到,多数动物所具有的技巧我们没有,除非“做梦”。下文所举的例子都是为了说明这一点,故选B。
    由文章第二段最后一句中“but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes”可知,档案展馆中有19世纪晚期第一批实用飞机的模型,故选A。

    由文章最后一段的最后一句“But imagine how life would change if we could achieve that."可知,美国军方的研究尚未取得成功,我们只能想象,如果真能实现这一想法,生活会有什么样子的变化,故选D。
    由文章最后一段的第一句和最后一句可知,一些仿生学概念还没有出现,人类还有很 长的路要走,才能使仿生学获得长足的进步,才能极大地改变人类的生活,故选D。第5部分:补全短文
