Aspirin's origins go back at least as early as 1758. In that year, Englishman Edward Stone noticed a distinctive bitter flvor in the bark of the willow tree. To Stone, this particular bark seem to have much in common with "Peruvian Bark", which had been used medicinally since the 1640s to bring down fevers and to treat malaria, stone decided to test the effectiveness of the willow bark. He obtained some, pulverized it into tiny pieces, and conducted experiments on its properties. His tests demonstrated that this pulverized willow bark was effective both in reducing high temperatures and in relieving aches and pains. In 1763, stone presented his tiding to the British Royal Society. Several decades later, further studies on the medicinal value of the willow bark were being conducted by two Italian scientists. These chemists, Brugnatelli and Fontana, determined that the active chemical that was responsible for the medicinal characteristics in the willow bark was the chemical salicin, which is the active ingredient of today's aspirin. The name "aspirin" is the trade name of the drug based on the chemical salicin, properly known as acetylsalicylic acid.The trade name "aspirin" was invented for the drug in the 1890s by the Bayer Drug Company in Germany. The fist bottles of aspirin actually went on sale to the publicjust prior to the turn of the century, in 1899.

The Internet: Changing Everything
Let’s do a little experiment: Take five minutes, and find some information about Angola. How did you get your information? How much information were you able to get? Chances are, you probably just went online and typed the word “Angola”. You were probably able to find out all sorts of things. This experiment shows us how useful the Internet is. Over the last 20 years, the Internet has changed the way that we live, work, and study. The biggest change has been the way that we access information. Twenty years ago, you would have needed an encyclopedia to learn about Angola. If you had wanted information, you would have had to get out of your chair, open your encyclopedia, and look up the word “Angola”. Today all you need is about five seconds and you’ll have the exact same information. This technology makes work a lot faster and more efficient. It has also made information storage a lot easier and neater. Twenty years ago, offices had papers and files all over the place. If you wanted to find a file, you had to open a desk drawer and find the right piece of paper. Today, many of us keep our files in cloud storage. Cloud storage is a technology that lets people store files on the Internet. All you have to do is to sign into the site, and you can find all of your files in seconds. Another big change is communication. These days more and more people are working from home. People have “home offices”. They just do their work at their house and e-mail it to their company. It makes life a lot easier. Some people don’t like these changes. They say that life is too convenient these days, and it is making people lazy. However, most people think that even if this technology makes us a little easier, it still has more benefits than disadvantages. In the end, it doesn’t matter what we think. The Internet has changed all of our lives forever.

Read the following passage and choose the best answer (A, B, C, D):
The penny press, which emerged in the United Sates during the 1830’s, was 1 a powerful agent of mass communication. These newspapers were little dailies, generally four pages in length, written for the mass taste. They differed from the 3 staid, formal presentation of the conservative press, with its emphasis on political and literary topics. The new papers were brief and cheap, emphasizing sensational reports of police courts and juicy scandals as well as human interest 5 stories. Twentieth – century journalism was already foreshadowed in the penny press of the 1830’s. 7 The New York Sun, founded in 1833, was the first successful penny paper, and it was followed two years later by the New York Herald, published by James 9 Gordon Bennett. Not long after, Horace Greeley issued the New York Tribune, which was destined to become the most influential paper in America. Greeley 11 gave space to the issues that deeply touched the American people before the Civil War – abolitionism, temperance, free homesteads, Utopian cooperative settlements, and the problems of labor. The weekly edition of the Tribune, with 13 100,000 subscribers, had a remarkable influence in rural areas, especially in Western communities. 15 Americans were reputed to be the most avid readers of periodicals in the world. An English observer enviously calculated that, in 1829, the number of 17 newspapers circulated in Great Britain was enough to reach only one out of every thirty – six inhabitants weekly; Pennsylvania in that same year had a 19 newspaper circulation which reaches one out of every four inhabitants weekly. Statistics seemed to justify the common belief that Americans were devoted to periodicals. Newspapers in the United States increased from 1,200 in 1833 to 21 3000 by the early 1860’s, on the eve of the Civil War. This far exceeded the number and circulation of newspapers in England and France.

Read the following passage and choose the best answer (A, B, C, D):
If we took a look at how people in Europe communicated just one hundred years ago, we would be very surprised to find out that English was hardly used outside the United Kingdom. The language most commonly used between people of different nationalities, and particularly the aristocracy, was French. In fact, French was the language of diplomacy, culture and education. However, that is not the case nowadays. English has replaced French as the international language of communication. Today there are more people who speak English as a second language than people who speak it as a first language. There are many reasons why English has become the language of international communication. Britain's colonization of many parts of the world had something to do with it, but it is mainly due to America's rise to the position of major world power. This helped spread popular American culture throughout the world bringing the language with it. But is it good that English has spread to all parts of the world so quickly? Language specialists seem to be divided over this issue. There are those who claim that it is important to have a language that the people in our increasingly globalized world have in common. According to others, English is associated with a particular culture and therefore promotes that culture at the expense of others. Linguists have suggested "Esperanto", an artificially put-together language, as a solution to international communication problems but without success. So, English will continue being the world language until some other language, maybe Chinese, which is the most widely-spoken native language in the world, takes over as the world's international language instead of English.

Read the following passage and choose the best answer (A, B, C, D):
It is commonly believed in the United States that school is where people go to get an education. Nevertheless, it has been said that today children interrupt their education to go to school. The distinction between schooling and education implied by this remark is important. Education is much more open-ended and all-inclusive than schooling. Education knows no bounds. It can take place anywhere, whether in the shower or on the job, whether in a kitchen or on a tractor. It includes both the formal learning that takes place in schools and the whole universe of informal learning. The agents of education can range from a revered grandparent to the people debating politics on the radio, from a child to a distinguished scientist. Whereas schooling has a certain predictability, education quite often produces surprises. A chance conversation with a stranger may lead a person to discover how little is known of other religions. People are engaged in education from infancy on. Education is, then, a very broad, inclusive term. It is a lifelong process, a process that starts long before the start of school, and one that should be an integral part of one's entire life. Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next. Throughout a country, children arrive at school at approximately the same time, take assigned seats, are taught by an adult, use similar textbooks, take exams and so on. The slices of reality that are to be learned, whether they are the alphabet or an understanding of the working of government, have usually limited by the boundaries of the subject being taught. For example, high school students know that they are not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. There are definite conditions surrounding the formalized process of schooling

Read the following passage and choose the best answer (A, B, C, D):
Cholera, a highly infectious disease, has resulted in millions of deaths time after time over centuries. It is caused by the bacterium Vibrio cholera, first isolated by Robert Koch in 1883. The organism enters the body through the digestive tract when contaminated food or water is ingested.The bacteria multiply in the digestive tract and establish infection. As they die, they release a potent toxin that leads to severe diarrhea and vomiting. This results in extreme dehydration, muscle cramps, kidney failure, collapse, and sometimes death. If the disease is treated promptly, death is less likely. In many countries, a common source of the organism is raw or poorly cooked seafood taken from contaminated waters. The disease is especially prevalent after a natural disaster or other destruction that results in a lack of fresh water. Sewer systems fail, and waste travels into rivers or streams; piped water is not available so people must take their drinking and cooking water from rivers or streams. Because people frequently develop communities along waterways, the disease can be spread easily from one community to the next community downstream, resulting in serious epidemics
