更多"Our surroundings are being polluted"的相关试题:
[单项选择]Our surroundings are being polluted faster than ever and it seems that people cannot prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials.
What can explain and settle this problem The fact is that pollution is caused by man—by his desire(欲望) for a modern way of life. We make "increasing industrialization"(工业化) our first aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the country-side into the cities, eager for the achievements of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourslves where we are going—and why It makes one think of the story about the pilot (飞行员) who told his passengers over the loudspeaker : "I’ve some good news and some bad news. The good news is that we ’re making rapid progress at 530 miles per hour. The bad news is that we are lost and don’t know where we’re going." The sad fact is that this becomes a true story when speaking of our modern society.According to the passage, what does man care most among the following
A. Health.
B. Industry.
C. Clean air
D. The future of the children
[简答题]Today our lives are changing faster than at any time in history. Here we report on two important changes that will have a big impact on our everyday lives in the future.
The cashless society Cash and bank-notes will disappear almost completely. They will be replaced by smart cards—plastic cards with microchip processors "loaded" with some money. When we pay for goods, the retailer will insert our smart card into a payment terminal and money will be transferred from our card to the retailer’s card. When all the money is used up, we will be able to "reload" it by inserting it into a telephone, dialing our bank account and transferring money to the card from the account. If we want to transfer money from our card to a bank account, we will use the same method. Smart cards will be able to hold several different currencies at the same time, so if we go aboard, we will use our smart cards in the same way.

Passage One
Animals are more like us than we ever imagined. They feel pain, they experience stress, and they show affection, excitement and love. All these findings have been made by scientists in recent years—and such results are beginning to change how we view animals.
Strangely enough, this research was sponsored by fast food companies like McDonald’s and KFC. Pressured by animal rights groups, these companies felt they had to fund scientists researching the emotional and mental states of animals.
McDonald’s, for instance, funded studies on pig behaviors at Purdue University, Indiana. This research found that pigs seek affection and easily become depressed if left alone or prevented from playing with each other. If they become depressed, they soon become physically ill. Because of this, and other similar studies, the European Union has banned the use of isolating pig stalls from 2012. In Germany, the government is encouraging p

[简答题]Our life is nothing more than our time. To kill time is therefore a form of suicide. We are shocked when we think of death, and we spare no pains, no trouble, and no expense to preserve life. But we are too often indifferent to the loss of an hour or of a day, forgetting that our life is the sum total of the days and of the hours we live. A day or an hour wasted is therefore so much life forfeited. Our life is a brief span measuring some seventy or eighty years in all. But nearly one third of this has to be spent in sleep; some years have to be spent over our meals; some in making journeys on land and voyages by sea; some in merrymaking; some in watching over the sickbeds of our nearest and dearest relatives. Now if all these years were to be reduced from the term over which our life extends, we shall find about twenty or thirty years at our disposal for active work. Whoever remembers this can never willingly waste a single moment of his life.

[填空题]Why does cream go bad faster than butter Some researchers think that it comes down to the structure of the food, not its chemical composition -- a finding that could help rid some processed foods of chemical preservatives.
