[单项选择]Acid rain, which is a form of air pollution, currently becomes a subject of great debate because of widespread environmental damage for which it has been blamed. It forms when oxides of sulfur (硫) and nitrogen (氮) combine with atmospheric moisture to yield sulfuric and nitric acids, which may then be carried long distances from their source before they drop in the form of rain. The pollution may also take the form of snow or fog or fall down in dry forms. In fact, although the term "acid rain" has been in use for more than a century — it is derived from atmospheric studies that were made in the region of Manchester, England — the more accurate scientific term would be "acid deposition". The dry form of such deposition is just as damaging to the environment as the liquid form.
The problem of acid rain originated with the Industrial Revolution, and it has been growing ever since. The severity of its effects has long been recognized in local settings, as exemplified by the spells of
A. deny that industries causes acid rain
B. admit that they are only partly responsible
C. claim that they are the main sources of pollution
D. think that the cause of acid rain needs further study

About Gender Differences
It is said that the first thing we ask about a newborn baby is "Is it a boy or a girl " But it might be considered that this is the first thing we ask ourselves whenever we meet anyone new. Perhaps this is why we find it so threatening if the cues are uncertain, and even more so if we find our first assumptions turns out to be incorrect.
Men are different from women. That would seem to be self-evident. They are different in ability, skill and behavior, but then, so is every individual person. So why do we make such a fuss about it It seems not unreasonable to suggest that the sexes are different because their brains are different, but then no two human brains are the same. It is suggested that our culture is in trouble because many women have been brought up to believe they should be as good as men. Well, why not
