I called out to him ,Have you got a light " He looked at me, shrugged and came over to light my cigarette. As he came close and lit the match, his eyes inadvertently locked with mine. At that moment, I smiled. I don’t know why I did that. Perhaps it was nervousness, perhaps it ’was because, when you get very close, one to another, it is very hard not to smile.

In the atmosphere, carbon dioxide acts rather like a one-way mirror -- the glass in the roof of a greenhouse which allows the sun’s rays to enter but prevents the heat from escaping.
According to a weather expert’s prediction, the atmosphere will be 3~C warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several metres and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere, possibly resulting in an alteration of the earth’s chief food-growing zones.
In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only
A. the greenhouse effect
B. the solar effects on the earth
