大学英语四级作文：Paper Still Has Weight

　　Humility is the best policy for technological forecasters.If you doubt that, remember those confident predictions of 30 years ago about the coming arrival of the “paperless office.”The arrival of computers everywhere in the workplace would,we were assured, soon make paper a thing of the past.Bill Gates vision of a computer on every desk has been more or less realized.Yet most of the folks working at those desks are knee-deep in paper.Research suggests our increasing use of paper is due to the introduction of the very digital technology that was supposed to wipe it out.

　　The case studies on email in the workplace, for example,show that it can lead to a 40 percent increase in paper consumption —and this doesn’t take into account the amount of paper used to print information from the Internet.There’s a wonderful irony here, because the personal computer —not to mention the laser printer —was invented in a lab set up by a copier company which was worried by all the talk of paperless offices.Our attachment to paper is truly amazing.

　　An astonishing proportion of email users, for example, prints off their messages and stores them all in filing cabinets.To the technological rationalist this behavior seems irrational.Why store email messages in paper files,which take up valuable real estate and are effectively unsearchable,when you can keep them on a hard disk and effortlessly look through them for keywords and phrases?The answer, of course, is it is the rationalists who are irrational.If people love paper, there must be a reason for it.And there is.

大学英语四级作文：Hotter or Colder ?

　　英语四级美文：Hotter or Colder ?

　　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 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) is 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.A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas.

　　At present we do not 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 are very lucky,the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.
