ЗАДАЙТЕ 5 ВОПРОСОВ К КАЖДОМУ ТЕКСТУ. СРОЧНО!
1.In the 21st century, our need for energy is greater than it has ever been. Fossil fuels like coal, oil and gas were formed millions of years ago, and when power stations burn them to create electricity, they release harmful gases into the atmosphere. There may be enough coal to last for a few hundred years, but known oil and gas reserves will run out in less than 50 years - and then what will we do?
Many scientists suggest turning to renewable energy, which means sources of energy that will never run out. It can be produced using the wind, the sun, waves or hot springs. The wind can turn large turbines to produce electricity, while energy from the sun can be collected in panels and stored in batteries. The movement of the sea can also be changed into electrical energy by using wave machines and, in parts of the world where there is volcanic activity, hot springs can produce geothermal energy. Unlike nuclear power, these are safe sources of energy that don’t pollute the environment.
Our dependence on fossil fuels has to end soon. Let’s hope that by the time all the reserves are gone, there will be enough alternative sources of efficient energy available. In the meantime, why don’t we try to reduce the amount of energy that we use?
2, Coca-Cola is probably the world’s best-known taste, and was the first truly global brand. Dr.JohnStith Pemberton, a pharmacist from Atlanta, Georgia, invented the drink. He mixed the Coca-Cola syrup, which was combined with carbonated water to make a popular soda fountain drink, in the local Jacob’s Pharmacy.
The first customers, who paid a hand¬some 5 cents a glass, pronounced the drink to be “excellent,” “delicious and refreshing.”
Dr. Pemberton’s partner and book-keeper, Frank M. Robinson, suggested the pro¬duct’s unusual name and wrote it down in his florid handwriting, feeling that the “two C’s would look well in advertising.” The first advertisement for the drink appeared in the Atlanta Journal, and handpainted oilcloth signs indicated which soda fountains offered the product. This was just the first step in a fantastic co-operation between the brand and advertising, which has made the trademark universally recognized.
A continuous stream of slogans have entered the collective consciousness, from “Drink Coca¬Cola” in 1886, the iconic “I’d Like to Teach the World to Sing” television advertisement of 1971, right up to the simple assertion “Real” of today’s campaign.
