问题     In the late 1960s, many people in North America turned their attention to environmental problems , and new steel-and-glass skyscrapers were widely criticized. Ecologists pointed out that a cluster of tall buildings in a city often overburdens public transportation and parking lot capacities.
    Skyscrapers are also lavish consumers, and wasters, of electric power. In one recent year, the addition of 17 million square feet of skyscraper office space in New York City raised the peak daily demand for electricity by 120,000 kilowatts—enough to supply the entire city of Albany, New York, for a day.
    Glass-walled skyscrapers can be especially wasteful. The heat loss(or gain)through a wall of half-inch plate glass is more than ten times than through a typical masonry wall filled with insulation board. To lessen the strain on heating and air-conditioning equipment, builders of skyscrapers have begun to use double-glazed panels of glass, and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain. However, mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings.
    Skyscrapers put a severe strain on a city’ s sanitation facilities, too. If fully occupied, the two World Trade Center towers in New York City would alone generate 2. 25 million gallons of raw sewage each year as much as a city the size of Stanford, Connecticut, which has a population of more than 109,000.
    Skyscrapers also interfere with television reception, block bird flyways, and obstruct air traffic. In Boston in the 1960s, some people even feared that shadows from skyscrapers would kill the grass on Boston Common.
    Still, people continue to build skyscrapers for all the reasons that they have always built them— personal ambition, civic pride, and the desire of owners to have the largest possible amount of rentable space.
Which of the following is NOT true according to the passage?
选项 A、Skyscrapers provide more usable space than other buildings.
B、The skyscrapers first appeared in the late 1960s.
C、Where there are skyscrapers, television reception is poor.
D、The two World Trade Center towers are skyscrapers.
答案B
解析 文章首句提到“20世纪60年代后期，北美的许多人开始关注环境问题，因此高楼受到了批评。”也就是说，从20世纪60年代后期开始，人们开始关注高楼而并不是说高楼是在20世纪60年代后期才开始出现的。
