Read the following passage and choose A, B, C or D to indicate the correct answer to each of the questions.

   If we believe that clothing has to do with covering the body, and costume with the choice of a particular form of garment for a particular use, then we can say that clothing depend primarily on such physical conditions as climate, health, and textile manufacture, whereas costume reflect social factors such as religious beliefs, aesthetics, personal status, and the wish to be distinguished from or to emulate our fellows.

   The ancient Greeks and the Chinese believed that we first covered our bodies for some physical reason such as protecting ourselves from the weather elements. Ethnologists and psychologists have invoked psychological reasons: modesty in the case of ancients, and taboo, magical influence and the desire to please for the moderns.

   In early history, costume must have fulfilled a function beyond that of simple utility, perhaps through some magical significance, investing primitive man with the attributes of other creatures. Ornaments identified the wearer with animals, gods, heroes or other men. This identification remains symbolic in more sophisticated societies. We should bear in mind that the theater has its distant origins in sacred performances, and in all period children at play have worn disguises, so as to adapt gradually to adult life.

   Costume helped inspire fear or impose authority. For a chieftain, costume embodied attributes expressing his power, while a warrior’s costume enhanced his physical superiority and suggested he was superhuman. In more recent times, professional or administrative costume has been devised to distinguish the wearer and express personal or delegated authority; this purpose is seen clearly in the judge’s robes and the police officer’s uniform. Costume denotes power, and since power is usually equated with wealth, costume came to be an expression of social caste and material prosperity. Military uniform denotes rank and is intended to intimidate, to protect the body and to express membership in a group. At the bottom of the scale, there are such compulsory costumes as the convict’s uniform. Finally, costume can possess a religious significance that combines various elements: an actual or symbolic identification with a god, the desire to express this in earthly life, and the desire to enhance the wearer’s position of respect.

Question: Why does the author mention the police officer’s uniform?

A. To illustrate the aesthetic function of costume

B. To identify the wearer with a hero

C. To suggest that police are superhuman

D. To show how costume signifies authority

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 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.

   Music therapy is using music to help people with a variety of problems. For example, it can help people with communication and speech problems speak better. It can help people with memory problems remember things from their past. Music therapy can also help people manage stress and be more relaxed. It can even make people with bad pain feel better.

   In music therapy, a music therapist works with one person alone or with small groups. The therapist meets with the person and does tests to find out what the problem is and what the person can do with music. Then the therapist decides what kind of music therapy to use. Some people sing, and others might compose music, but a person doesn't need to know about music to be helped by music therapy. There are options such as listening to music and dancing to music. Research shows that these activities are good for the body and for the mind.

   Homes that take care of elderly people often have music therapy programs. The programs help the elderly be more energetic and also help with memory problems. Some hospitals have music therapy for patients who are in a lot of pain. Music can affect a part of the brain that reduces pain.

   Trevor Gibbons is one example of a person who was helped by music therapy. In 2000, he was putting in windows on the fourth floor of a building when he fell. He was in the hospital for over a year. He was in a lot of pain, and he couldn’t talk. He went from the hospital to a rehabilitation center that has a music therapy program, and a music therapist worked with him for several years. He could sing more easily than he could talk. Trevor says that music also helped him manage loneliness, sadness, and pain after he was hurt. Music and the music therapist inspired him, and he has written and sung many songs. He has even recorded CDs and performed at Lincoln Center in New York.

Question 9: It is stated in the passage that _______.

A. homes for the aged don’t have music therapy programs

B. in music therapy some people sing or even compose music

C. Trevor Gibbons hurt himself when he fell off the fifth floor

D. listening and dancing to music are not included in music therapy

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. ...

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?
