When my first wartime Christmas came, I was in basic training in New Jersey and not sure if I could make it home for the holidays. Only on the afternoon of December 23 was the list of men who would have three-day holidays posted. I was one of the lucky soldiers. It was Christmas eve when I arrived home, and a light snow had fallen. Mother opened the front door. I could see beyond her, into the corner of the living room where the tree had always stood. There were lights, all colors, and ornaments (装饰物) shining against the green of a pine. “Where did it come from?” I asked.

     “I asked the Gates boy to cut it,” my mother said. “I wouldn’t have had one just for myself, such a rush！He just brought it in this afternoon…” The pine reached to the proper height, almost to the ceiling, and the tree top crystal star was in its place. A few green branches reached about a little awkwardly at the side, I thought, and there was a bit of bare trunk showing in the middle. But the tree filled the room with warm light and the whole house with the pleasant smell of Christmas. “It’s not like the one you used to find,” my mother went on. “Yours were always in good shape. I suppose the Gates boy didn’t know where to look for a good one. But I couldn’t be fussy (挑剔的)．”

    “Don’t worry,” I told her. “It’s perfect.” It wasn’t, of course, but at the moment I realized something for the first time: all Christmas trees are perfect．

It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil) creating a greenhouse effect-holding in heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.

Another view, less widely held, is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earth’s temperature-a result that would be equally disastrous（灾难的）. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do riot know for sure that either of these conditions will happen(though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we very lucky, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.

As pointed out at the beginning of the passage, people used to think that air pollution ______.

       A．caused widespread damage in the countryside

       B．affected the entire eastern half of the United States

       C．almost brought worldwide effect

       D．existed merely in urban and industrial areas

As far as the greenhouse effect is concerned, the author _____________.

       A．shares the same view with the scientists

       B．is uncertain of its occurrence

       C．rejects it as being ungrounded（无根据的）

       D．thinks that it will increasingly destroy the world soon

It can be inferred from the passage that                    .

       A．raising the world’s temperature a little would not do much harm to life on the earth

       B．lowering the world’s temperature a little would lead to agricultural disasters

       C．almost no temperature variations have occurred over the past decade

       D．the world’s temperature will remain stable forever

This passage is primarily concerned with              .

       A．the greenhouse effect in the world

       B．the measures to adjust the climate

       C．the potential effect of air pollution

       D．the measures to protect the environment
