Read the passage and mark the letter A , B , C or D to answer the questions from 1 - 7

PANDEMIC DISEASES

Diseases are a natural part of life on earth . If there were no diseases , the population would grow too quickly , and there would not be enough food or other resources , so in a way , diseases are natural ways of keeping the Earth in balance . But sometimes they spread very quickly and kill large numbers of people . For example , in 1918 , an outbreak of the flu spread across the world , killing over 25 million people in only six months . Such terrible outbreaks of a diseases are called pandemics

Pandemics happen when a disease changes in a way that our bodies are not prepared to fight . In 1918 , a new type of flu virus appeared . Our bodies had no way to fight this new flu virus , and so it spread very quickly and killed large numbers of people . While there have been many different pandemic diseases throughout history , all of them have a new thing in common . First , all pandemic diseases spread from one person to another very easily .

Second , while they may kill many people , they generally do not kill people very quickly . A good example of this would be the Marburg virus . The Marburg virus is an extremely infectious disease . In addition , it is deadly . About 70 - 80 % of all people who get the Marburg virus died from the disease . However , the Marburg virus has not become a pandemic because most people die within three days of getting the disease . This means that the virus does not have enough time to spread a large number of people . The flu virus of 1918 , on the other hand , generally took about a week to ten days to kill its victims , so it had more time to spread .

While we may never be able to completely stop pandemics , we can make them less common . Doctors carefully monitor new diseases that they fear could become pandemics . For example , in 2002 , and 2003 , doctors carefully watched SARS . Their health warnings may have prevented SARS from becoming a pandemic .

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

  Since water is the basis of life, composing the greater part of the tissues of all living things, the crucial problem of desert animals is to survive in a world where sources of flowing water are rare. And since man’s inexorable necessity is to absorb large quantities of water at frequent intervals, he can scarcely comprehend that many creatures of the desert pass their entire lives without a single drop.

   Uncompromising as it is, the desert has not eliminated life but only those forms unable to withstand its desiccating effects. No moist- skinned, water-loving animals can exist there. Few large animals are found. The giants of the North American desert are the deer, the coyote, and the bobcat. Since desert country is open, it holds more swift-footed running and leaping creatures than the tangled forest. Its population is largely nocturnal, silent, filled with reticence, and ruled by stealth. Yet they are not emaciated. Having adapted to their austere environment, they are as healthy as animals anywhere else in the word. The secret of their adjustment lies in the combination of behavior and physiology. None could survive if, like mad dogs and Englishmen, they went out in the midday sun; many would die in a matter of minutes. So most of them pass the burning hours asleep in cool, humid burrows underneath the ground, emerging to hunt only by night. The surface of the sun-baked desert averages around 150 degrees, but 18 inches down the temperature is only 60 degrees.

Question: The title for this passage could be

A. “Man’s Life in a Desert Environment”

B. “Desert Plants”

C. “Animal Life in a Desert Environment”

D. “Life Underground”

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

   Millions of people are using cellphones today. In many places, it is actually considered unusual not to use one. In many countries, cellphones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

   The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

   On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

   What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

   As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.

Question: According to the passage, cellphones are very popular with young people because _______.

A. they make them look more stylish

B. they are worrying

C. they are a means of communication
