问题     There are approximately three quarters of a ton of termites (白蚁) for every person on Earth. It now turns out that these critters (生物) may be helping to alter the climate and affect man’s life.
    For years scientists have been saying that carbon dioxide sent into the atmosphere by the burning of fuels might lead to the rise in temperatures of the whole earth, owing to the greenhouse effect in which the gas prevents the escape of heat into outer space. Now an international team of researchers has discovered that termites generate more than twice the carbon dioxide that fuel burning does. And this production, which comes from the insects’ eating and consuming of different kinds of vegetables and wood has risen greatly. This is chiefly because man has cut so many trees in order to open more land and thus has provided large quantities of food for the insects in the form of tiny pieces of wood.
    The output from the burning of fuels is of greater concern, however, because it is continuing to rise steadily and so far no effective measures have been taken to reduce the amount of carbon dioxide produced in this way. Production by termites, on the other hand, is not likely to increase much more.
Which of the following statements is NOT true?
选项 A、It is the production by termites that is now of greater concern.
B、What scientists worry more about is the output from burning fuels.
C、The output from burning fuels is now rising steadily.
D、The burning of fuels generates much less carbon dioxide than termites do.
答案A
解析 本题仍是一道判断是非题。问下面哪个选项是不正确的。利用查阅式阅读法和排除法，针对每个选项所提示的内容并对照原文相关部分，我们不难找出本题的正确答案应是A“白蚁产生的二氧化碳量现在引起了人们的极大关注”。此种说法与文章的最后一段内容不符。文章最后一段指出，然而，燃料燃烧的释放量问题是一个备受关注的问题，因为它在呈现出稳定上升的趋势。而且，迄今为止并未找到有效的办法以减少由此产生的二氧化碳含量。而另一方面，白蚁产生的二氧化碳量不可能会增加许多的。
