VI. Read the passage carefully and choose the correct answer.

Scientists believe they now have scientific evidence to prove that ecosystems work better when there is greater variety of species within them. This biodiversity is being lost destroying natural mechanisms that could repair the damage caused by man.

Findings show that losing plants and animals is not only reducing our quality of life but actually endangering our very existence. We cut down rich rainforests and replace them with one species plantations, such as pine and eucalyptus. We plough up meadows rich in different grasses and herbs and replace them with one grass, for instance rye or wheat.

When a natural ecosystem is simplified the basic processes in the ecosystem are altered and even damaged. Without their biodiversity they are not able to serve as the natural clearners of our planet. No longer are they able to absorb the carbon dioxide that is being produced in excess. The result is global warming, caused by the increase in the 'greenhouse effect', and ultimately, or even 'sooner, there will be' a change in the world's climate.

b. To give examples of the loss of biodiversity.

d. To show how ecosystems can work better.

54. What, according to the passage, might be the final result of the simplification of natural ecosystems?

a. The basic processes are altered            b. There is loss of biodiversity

c. There is global warming                  d. There is a change in the climate.

THE POSTAGE STAMP

Before the invention of the postage stamp, it was difficult- to send a letter to another country. The sender paid for the letter to travel in his or her own country. Then the person in other country paid for that part of the trip. If the letter crossed several coutries, the problem was worse.

Rowland Hill, a British teacher, had the idea of a postage stamp with glue on the back. The British post office made the first stamps in 1840. They were the Penny Black and the Twopence Blue. A person bought a stamp and put it on a letter. The post office delivered the letter. When people received letters, they didn't- have to pay anything. The letters were prepaid.

Postage stamps became popular in Great Britain immediately. Other countries started making their own postage stamps very quickly. There were still problems with -international mail. Some countries did

not want to accept letters with stamps from another country. Finally, in 1874 a German organized the Universal Postal System. Each country in the UPS agree to accept letters with prepaid postage from the other members. Today the offices of the UPS are in Switzerland, almost every country in the world is a member of this organization. It takes care of any international mail problems.

Today post offices in the every country sell beautiful stamps. Collecting stamps is one of the most popular hobbies in the world, and every stamp collector knows about the Penny Black and the Two pence Blue.

1. Before postage stamps, two people paid-for letters to travel in two countries.

2. A teacher invented the postage stamp.

3. The first two stamps were colored black and blue.

4. A stamp shows that the postage is prepaid.

5. Postage stamps solved all mail problems immediately.

6. Members of the UPS accept prepaid letters from other countries.

7. Stamp collecting is a popular hobby.

Exercise 5. Read the passage carefully, then choose the correct answers.

The natural world is under violent assault from man.

The seas and rivers are being poisoned by radioactive wastes, by chemical discharges and by the dumping of dangerous toxins and raw sewage. The air we breathe is polluted by smoke and fumes from factories and motor vehicles; even the rain is poisoned.

It's little wonder forests and lakes are being destroyed and everywhere wildlife is disappearing. Yet the destruction continues.

Governments and industries throughout the world are intensifying their efforts to extract the earth's mineral riches and to plunder its living resources. The great rainforests and the frozen continents alike are seriously threatened. And this despite the warnings of the scientific community and the deep concern of millions of ordinary people.

Despite the fact, too, that we can create environmentally-clean industries, harness the power of the sun, wind and waves for our energy needs and manage the finite resources of the Earth in a way that will safeguard our future and protect all the rich variety of life forms which share this planet with us.

But there is still hope. The forces of destruction are being challenged across the globe - and at the spearhead of this challenge is Greenpeace.

Wherever the environment is in danger, Greenpeace has made a stand.

Its scientific presentations and peaceful direct actions at sea and on land have shocked governments and industri1es into an awareness that Greenpeace will not allow the natural world to be destroyed. Those actions, too, have won the admiration and support of millions.

Now you can strengthen the thin green line; you can make your voice heard in defence of the living world by joining Greenpeace today. Thank God someone's making waves.

Exercise 4. Read the passage carefully, then choose the correct answers.

The search for alternative sources of energy has led in various directions. Many communities are burning garbage and other biological waste products to produce electricity- Converting waste products to gases or oil is also an efficient way to dispose of wastes. Experimental work is being done to derive synthetic fuels from coal, oil shale, and coal tars. But to date, that process has proven expensive. Other experiments are underway to harness power with giant windmills. Geothermal power is also being tested. Some experts expect utility companies to revive hydroelectric power derived from streams and rivers. Fifty years ago hydroelectric power provided one third of the electricity used in the United States, but to day it supplies only 4 percent. The oceans are another potential source of energy. Scientists are studying ways to convert the energy of ocean currents, tides, and waves to electricity. Experiments are also underway to make use of temperature differences in ocean water to produce energy.
