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.
The best title for this passage might be______.
选项
A、The Effect of Termites on the Climate
B、Why Carbon Dioxide Can Affect the Climate
C、The Output from Burning Fuel
D、How Greenhouse Works
答案
A
解析
本题问本文的最佳标题是什么。根据文章的主题大意,我们可以推断出本题的正确答案应选A“白蚁对气候的影响”。其他三个选项都是错误的。
