Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived . Biological death occurs when changes in the organism lead to the "breaking up" of vital cells and tissues. Death is then unchangeable and final. Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism , cooling delays the processes leading to biological death. To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta's heart became active once more. After fifteen minutes, spontaneous breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal. All of the following indicate that the monkey has almost restored to her original physical state except the fact that A) her heart beat again. B) she regained her normal breath. C) she rejected a penicillin injection. D) she acted as lively as a healthy monkey.

There is no place like home--as long as it is far enough away, it seems. Britain has become a nation of nomads ,with nearly half of us living more than 100 miles from the town or village where we grew up, research shows. The trend is being fuelled by the Internet, better communications and property wealth. People who move away fit into four separate categories--Sheep, Hens, Cows or Pigs. Sheep are people who change home for economic and emotional peace. Hens are home and environment care-seekers. Cows are career or work shifters, while pigs are people caught up in grand parental support. It is far from the common believed idea of Coronation Streets, where close-knit generations of the same family live within a few streets of each other throughout their lives. Less. Than 20 percent of people now live in the town where they were born. Instead, young adults move away to find work, get married or seek adventure. Many use the Internet to work from a home which need not be within easy traveling distance of their workplace. Also joining the moving crowd are older people who either move to be near grandchildren or retire to new homes. One in ten of those who do make away makes a complete break, and now lives 500 miles or more from where they grew up. Women are likely to leave as men, a sign of independence that would not have excited in the 1950s and 60s. People in the North-East, North-West, Yorkshire and prefix = st1 /Scotlandare the most likely to live in the community where they were born, the study found. According to the research in the passage, British people tend to _ . A) become more independent whenever they graduate or grow up B) live or work far away from where they were born or grew up C) live near their own homes D) become more close to each other

In the West, advertisements are the fuel that makes mass media work. Many TV stations, newspapers, magazines, radio stations are privately owned. The government does not give them money. So where does the money come from? From advertisements. Without advertisements, there would not be these private businesses. Have you ever asked yourself what advertising is? Through the years, people have given different answers to the question. For some time it was felt that advertising was a means of "keeping your name before the public". And some people thought that advertising was "truth well told". Now more and more people consider it in this way: Advertising is the paid, non-personal, and usually persuasive presentation of goods, services and ideas by some certain sponsors through various media. First, advertising is usually paid for. Various sponsors pay for the advertisements we see, read, and hear over the various media. Second, advertising is non-personal. It is not face-to-face communication. Although you may feel that a message in a certain advertisement is aimed directly at you, in fact, it is directed at large groups of people. Third, advertising is usually persuasive. Directly or indirectly it asks people to do something. All advertisements try to make people believe that the product, idea, or service advertised can benefit them. Fourth, the sponsors of the advertisement must show their names. From the advertisement, we can see if the sponsor is a company, or a single person. Fifth, advertising reaches us through old and modern mass media. Included in the old media are newspapers, magazines, radio, television, and films. Modern media include emails, matchbox covers, and boards on top of buildings. Which of the following is considered modern mass media? _ . A) Newspapers B) Emails C) Magazines D) Films

Many animal and plant species have become extinct and many more are in critical danger. Finding ways to protect the earth's wildlife and conserve the natural world they inhabit is now more important than ever. Dodo The Dodo is a classic example of how human caused damage to the earth's biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island's trees and lived unthreatened until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and last one was killed in 1681. Rhinos The Rhino horn is a highly priced item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves . Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers . The Giant Panda The future of the World Wildlife Fund's symbol is far from certain. As few as 1000 remain in the wild. The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison. However, The panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose one of the most serious threats to the animals continued existence. Whales The International Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that one-third the world's oceans have been declared whale sanctuaries , 7 out of 13 whale species remain endangered. Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths. Tigers The last 100 years has seen a 95% reduction in the numbers of... What is the best title for the passage? A) What caused the animals to go extinct?
