[单项选择]There are approximately three quarters of a ton of termites (白蚁) for every person on Earth. It now turns out that these critters 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
A. Carbon dioxide in the atmosphere carries heat into outer space so as to change the climate.
B. Carbon dioxide may escape into the greenhouse so that the Earth will be made warmer.
C. As carbon dioxide keeps heat from escaping into outer space, the Earth may become warmer.
D. Carbon dioxide may make the Earth warmer because it lets the heat escape into outer space.

46) For centuries the smoking of tobacco in cigarettes, cigars, and pipes has produced controversy over possible health hazards, but only since the 1950’s has sufficient scientific evidence accumulated to make possible a thorough evaluation of the health risk.
Scientific investigation of the relationship of smoking and health gained impetus after the beginning of the 20^th century, then an increase in lung cancer was noted. As the use of tobacco increased, studies improved. (47) Although some gaps in knowledge still exist, the information now available is sufficient to permit making sound judgments, based on the converging lines of evidence.
