The weather is not beautiful all of the time. Perhaps you can remember a day when bad weather made you afraid. One kind of bad weather that scares many people is called a thunderstorm. This is what happens when there is a thunderstorm. First, you see a sudden flash of bright light. A few seconds later you hear a loud rumbling sound. This quick flash is called lightning and the loud sound is called thunder. Lightning is colorful , but it can cause serious problems. Lightning is electricity that is moving very rapidly. It may be moving between a cloud and the ground, between two clouds, or between two parts of the same cloud. The lightning heats the air around it. This hot air expands, or get bigger, and it causes the air to move in waves. The air waves pass you in a series, one after another. For this reason, you may hear many rumbles and not just one sound.

____ 29/ Lightning may move between a cloud and the ground.

____ 30/ Thunder is a very bright light in a thunderstorm.

____ 31/ When you hear thunder you may hear a series of loud sounds and not one

big sound. This is because the air waves pass one after another.

____ 32/ Lightning always moves rapidly.

Find 7 mistakes in the paragraph and correct them:

Alternative sources of energy

In the " Search for Free Energy", Tutt's recently released book, he quotes " We ought to be able to obtain the energy we need without the consumption of material." These are not the words of some modern-day environmentalist, but of Nikola Tesla, in 1890. Among his invention was the device to generate electricity by harnessing "coming energy". The search for free, and expensive energy continues. Researchers are looking for "fuelless" technologies that will not pollute or run out, and they are not referring to the puny contribution of solar or wind power. The science establishment has so far been proven correct, there's no such thing as a free energy lunch but that hasn't stopped mad scientists trying. They've come up with numerable patents of "over unity" contraptions, supposed giving out more energy than you put in to get them going. The story is fascinating and rarely heavy-going, although the quotes can be overlong and the diagrams are adequately displayed. Tutt admits that only a fraction of what is claimed is true. But it's also true to say we cannot afford to dismiss them out of hand, as one of these conforming investigators may just be able to save our planet from climate change.

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. Alexander Fleming discovered super-antibodies which can kill bacteria and viruses inside the cells that house them. TrueFalse 5. GM food is easily available in the U.S. and Europe.

The LIFE AND DEATH OF PUNK

Although the punk movement didn't gain cultural popularity the late 1970's, the origins of the subbculture stemmed from cultural scenes in the UK and USA earlier in the decade with radical musician such as The Velvet Underground and new thinkers like Malcolm McClaren. As with any subculture, the first stage must be the birth of the subculture which is led by cultural leader. these leaders inspire the styles and values that will become part of the subculture. In the case of punk, McClaren was very muc hthe stylist of the stylist of the punk look, selling daring clothes that the punk culture came to embrace.

Punk began in its fullest form in the 1970s, when the daring and anti-establishment concepts of the these pioneers took a more popular form. Punk sprang up largely as a result of a weakening economy and high levels of unemployment. Social and political problems are often the reason behind the next stage of subcultural development; the subcultural embrace. This is when the subculture is at its most dynamic, and is becoming increasingly accepted.

After that the subculture plateaus. This is when it become stable ans people demonstrate sub-norms which include shared ways of dressing, shared values and beliefs, and shared forms of film or music. in terms of punk, this can be seen in such things as Mohawks, a particularly striking hairstyles, and piercings. Punk often have many facial piercing which make them stand out from the norm. This need for individualism is quite strong in youth subcultures, yet at the same time is a contradiction because these very people are copying from within their groups. A striking feature at this stage is the onset of deviant subcultures, which take some charateristic. As well as often exhibiting anti-social behaviour, they distance themselves from the main subculture by mutual dislike. In the culture of punk, skinhead are an apt example of this, exhibiting all th key features of a deviant subculture.

The important thing to note is that whereas the main subculture continues through the cultural plateau to then suffer from eventual rejection, the deviant subculture continues for much longer. A youth subculture usually fade away after an amount of time as it becomes more and more old-fashioned; something which young people never like to be associated with. the 'accepted' subcultures are then replaced by a newer and more cutting-edge subculture, in the case of punk, dance and new romantic subcultures emerged which saw the end of the established subculture of punk
