【篇一】2021年上半年大学英语四级美文赏析

　　I believe in the supreme worth of the individual and his right to life,liberty, and pursuit of happiness.I believe that every right implies a responsibility;every opportunity, an obligation,every possession, a duty.I believe that the law was made for man and not man for the law;that government is the servant of the people and not their master.

　　I believe in the dignity of labor whether with head or hand;that the world owes no man a living but that it owes every man an opportunity to make a living.I believe that thrift is essential to well-ordered living and that economy is a prime requisite of a sound financial structure,whether in government,business or personal affairs.I believe that truth and justice are fundamental to an enduring social order.

　　I believe in the sacredness of a promise,that a man’s word should be as good as his bond;that character — not wealth or power or position —is of supreme worth.I believe the rendering of useful service is the common duty of mankind and that only in the purifying fire of sacrifice is the dross of selfishness consumed and the greatness of the human soul set free.

　　I believe in the all-wise and all-loving God,named by whatever name;and that individual’s highest fulfillment,greatest happiness and widest usefulness are to be found in living in harmony with his will.I believe that love is the greatest thing in the world;that it alone can overcome hate; that right can and will triumph over might.

　　Hearing can soothe and comfort.The snapping of logs in the fireplace,the gossipy whisper of a broom,the inquisitive wheeze of a drawer opening —all are savored sounds that make us feel at home.In a well-loved home,every chair produced a different,recognizable creak,every window a different click, groan or squeak.

　　The kitchen by itself is a source of many pleasing sounds.Every place, every event has a sound dimension.The sense of hearing can perhaps be restored to modern man if he better understands its worth and how it works.Most people would be surprised to discover how far the sense can be pushed by cultivation.At a friend’s house recently,my wife opened her purse and some coins spilled out,one after another, onto the floor.“Three quarters, two dimes,a nickel and three pennies,”said our host as he came in from the next room.

　　And as an afterthought:“One of the quarters is silver.”He was right, down to the last penny.“How did you do it?” we asked.“Try it yourself.” he said.We did, and with a little practice we found it easy.Curiously, evidence indicates that people need sound.When we are lost in thought,we involuntarily drum with our fingers or tap with a pencil —a reminder that we are still surrounded by a world outside ourselves.

　　Just cutting down reflected sound can produce some odd results.The nearest thing on earth to the silence of outer space,for example, is the “anechoic chamber”at the Bell Telephone Laboratories in Burray Hills, N.J.,which is lined with material that absorbs 99.98% of all reflected sound.Men who have remained in the room for more than an hour report that they feel nervous and out of touch with reality.

　　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.
