Nowadays in the news you can read a lot about biotechnology and the controversies about it and perhaps you ask yourself what it is exactly. Well, this article is going to give you a brief history of the field of biotechnology and show you that, although the word “biotechnology” was first used in 1919, we have been using biotechnology for many thousands of years in ways that are completely uncontroversial. It will also look at the more modern developments which have started intense debate. When you are drinking a cold beer on a hot day, or eating a delicious cheese sandwich, you can thank biotechnology for the pleasure you are experiencing. That’s right! Beer, bread and cheese are all produced using biotechnology. Perhaps a definition will be useful to understand how. A standard definition is that biotechnology (or biotech for short) is the application of science and engineering to the direct or indirect use of living organisms. And as you know, the food and drink above are all produced by the fermentation of micro-organisms. In beer, the yeast multiplies as it eats the sugars in the mixture and turns them into alcohol and CO2. This ancient technique was first used in Egypt to make bread and wine around 4000BC! Antibiotics are used to prevent and treat diseases, especially those caused by bacteria. They are natural substances that are created by bacteria and fungi. The first antibiotic was made in China in about 500BC – to cure boils. In 1928 Alexander Fleming discovered penicillin and it was considered a medical miracle. Modern research is looking at the creation of super-antibodies which can kill bacteria and viruses inside the cells that house them. Our modern consumer society produces a lot of waste which needs to be disposed of safely and without harmful end products. Environmental biotechnology can help. Indeed, the use of bacteria to treat sewage was first practiced in 1914 in Manchester, England. Vermiculture or using worms to treat waste is another environmentally-friendly practice and the end product is a natural fertiliser. Bacteria have even been developed to help with problems such as oil spills. They convert crude oil and gasoline into non-toxic substances such as carbon dioxide, water and oxygen and help create a cleaner, healthier environment. These examples of biotechnology are accepted by most people. However, the discovery of the DNA structure by Watson and Crick in 1953 was the beginning of the modern era of genetics and the following areas of biotech are very controversial. Read on… The genetic modification of plants and crops has been in practice for many years. This involves changing the genetic code of these plants so that they are more resistant to bad conditions like drought, floods and frost. Supporters of GM food say that it can offer the consumer better quality, safety and taste and for over a decade Americans have been eating GM food. However, things are very different in Europe where genetically modified food is very strictly regulated and regarded with deep suspicion by the public. GM food has even been called “Frankenfood” in the press, a term inspired by the novel Frankenstein by Mary Shelley. There is a great cultural divide between America and Europe over whether such food is safe to eat and will not harm the environment and the discussion is still in progress. 1997 saw the birth of Dolly the sheep, the first animal cloned from an adult cell. This was a remarkable achievement which created world-wide debate on the ethical issues surrounding cloning. International organisations such as the European parliament, UNESCO and WHO all declared that human cloning is both morally and legally wrong. However, we need to make a distinction between reproductive cloning and therapeutic cloning. Nowadays the idea of reproductive cloning – creating a copy of another person - is no longer interesting for researchers. Instead therapeutic cloning is creating excitement in the biotech world. Key to this technique is stem cells, which are master cells that have the potential to become any other kind of cell in the body e.g. nerve cells, blood, heart muscle or even brain cells. Stem cells themselves have generated a lot of controversy as it was believed that only human embryos could provide them. However, it now appears that adult stem cells offer the same possibility. This would mean that a patient who suffered a heart attack could provide doctors with his adult stem cells which could then be implanted back into his heart and used to create heart muscle, replacing the muscle that was damaged. As the genetic code is identical, there would be no problem of the body rejecting the implant as, unfortunately, happens with organ transplants. In the future, biotechnologists hope that stem cells could be used to grow entire organs. In this way biotechnology offers the hope of revolutionising medical treatment. In this brief overview of the history of biotechnology we have jumped from making bread to making human organs - an enormous leap- and it is clear that these modern practices raise many controversial issues. However, despite the debate, we can imagine that as biotechnology has been around for many years, it will still be around for some time to come - but who knows where it will take us? Questions: After reading, choose the best answer for the following questions 1. What is the main topic of the article? Brief history and modern developments of biotechnology Benefit of biotechnology Modern research in biotechnology 2. What does the pronoun "IT" in the first paragraph refer to? Biotechnology The article The word "Biotechnology" 3. Which products were first made with fermentation of micro-organisms? Beer, bread and cheese Bread and wine Beer and cheese Decide whether the statement below is True or False. 4.

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.

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 .

Question 1 : According to paragraph 1 , how are diseases a natural part of life on Earth ?

A. They prevent pandemics B. They help control the population

C. They led the world grow quickly D. They kill too many people

Question 2 : Based on the information in the passage the term " pandemics " can be explained as .............................................

A. diseases with no cure

B. a deadly kind of flu

C. diseases that spread quickly and kill large numbers of people

D. new disease like SARS or the Marburg virus

Question 3 : According to the passage , all of the following are true of the 1918 flu pandemic EXCEPT that ...............................................

A. it involved a new kind of flu virus B. it killed over 25 million people

C. it was the last pandemic in history D. it took a little over a week to kill ít victims

Question 4 : The word " it " in the passage refers to .......................

A. disease B. flu virus C. pandemics D. bodies

Question 5 : Which of the following is mentioned as a common feature of all pandemic diseases ?

A. They spread from people to people very quickly

B. It kill many people very quickly

C. They do not kill people very quickly

D. They kill all the victims

Question 6 : The word " monitor " in the passage is closest is meaning to ........................

A. fight B. prevent C. watch D. avoid

Question 7 : The author mentions SARS in order to .............................

A. give an example of a highly dangerous disease

B. suggest that SARS will never become a pandemic

C. give an example of the successful prevention of a pandemic

D. suggest that there may be a new pandemic soon .
