Dr. Jonas Salk is credited with developing the first vaccine to fight against the dreaded polio. Born in New York in 1914, Salk received his medical degree from New York University College of Medicine in 1939 and later attended the School of Public Heath at the University of Michigan.
Salk was very interested in preventive medicine. He worked for the army on producing a vaccine against influenza for five years from 1942 to 1947. In 1949, a group at Harvard University led by John Enders developed a method to grow the polio virus in quantity so that it could be studied further. This discovery was important as it allowed Salk and his fellow workers to study the disease in greater detail.
By 1952, Salk’s group had successfully tested a polio vaccine using an inactive polio virus. In 1954, there were field tests done on a large scale. Initially, there were many different vaccines being used among the public, and there were some deaths associated with the vaccinations. However, Salk’s vaccine proved to be the best and was used without further problems. What was once a dreaded killer had been tamed by the work of Dr. Jonas Salk and co-workers.

Polyester is now being used for bottles. ICI., the chemicals and plastics company, believes that it is now beginning to the grip of glass on the bottles business and thus take advantage of this huge market.
All the plastics manufacturers have been experiencing hard times as their traditional products have been doing badly worldwide for the last few years. Between 1982 and 1984 the Plastics Division of ICI had lost a hundred and twenty million dollars and they fell that the most hopeful new market was in packaging, bottles and cans.
Since 1982 it has opened there new factories producing “Melinar”, the raw material from which high quality polyester bottles are made.
The polyester bottle was born in the 1970s, when soft drink companies like Coca Cola started selling their drinks in giant two-litre containers. Because of the build-up the pressure of gas in these large containers, glass was unsuitable. Nor was PVC, the plastic which had been used for bottles since the 1960s, suitable for drinks with gas in them. A new plastic had to the made.
Glass is still cheaper for the smaller bottles, and will continue to be so unless oil and plastic become much cheaper, but plastic does well for the larger sizes.
Polyester bottles are virtually unbreakable. The manufacturers claim they are also lighter also, less noisy when being handled, and can be re-used. Shopkeepers and other business people are unlikely to object to a change from glass to polyester, since these bottles mean few breakages, which are costly and time- consuming. The bottles with interesting shapes, to try and make them visually more attractive to the public.
The next step could be to develop a plastic which could replace tins for food. The problem here is the high temperatures necessary for cooking the food in the container.
61. Plastics of various kinds have been used for making bottles
A. since 1982
B. since the 1970s but only for large bottles
C. since the 1960s but not for liquids with gas in them
D. since the 1970s but only for large bottles.
62. Why is ICI’s Plastics Division interested in polyester for bottles?
A. The other things they make are not selling well
B. Glass manufacturers cannot make enough new bottles
C. They have factories which could be adapted to make it
D. The price of oil keeps changing
63. Why aren’t all bottles now made of polyester?
A. The price of oil and plastic has risen
B. It is not suitable for containing gassy drinks
C. The public like traditional glass bottles
D. Shop-keepers dislike re-usable bottles.
64. Manufacturers think polyester bottles are better than glass bottles because they
A. are cheaper
B. are more suited to small sizes
C. are more exciting to look at
D. do not break easily
65. Plastic containers for holding food in the same way as cans.
A. have been used for many years.

D. are the first things being made in the new factories.
VI. For questions 66 – 70, choose the answer (A, B, C or D) which you think fits best according to the text.
Although party invitations no longer frightened me, I still found myself making careful preparations for this particular party. I got a hair-cut. laid out my best suit, selected a special, tie, and cuff links. I had recently gone on a diet, but because I didn’t want to look too thin. I discontinued it. What should I bring my hosts? Flowers? What kind of wine? Sherry? Or possibly even champagne? Meeting new people was still a major undertaking.
It was scheduled for this Saturday and I decided to take a cab to the suburb where it was being held. It was early autumn and the weather had been mild, but that morning it turned cold and rainy, and as I listened to the steam hissing in my radiator, it already felt like midwinter. Trees, visible from my window, covered will foliage only yesterday, had become bare overnight. Churning clouds augured a further change in the weather. From my new paper I learned that a hurricane which had already struck another state as on its way to New York, though it might veer out to sea. The storm left destruction in its wake. In one village an entire cottage was sheared from its foundation and blown into the ocean together with its occupants.
As I lay in bed the morning of the party, I envisioned a change also taking place in me. A loose tooth which hadn’t bothered me suddenly sent a stabbing pain through my jaw. Ordinarily I’m not to headaches, but I awoke with a dull ache on the left side of my head. Several disturbing dreams had given me a restless night, though 1 could only remember them vaguely. In one dream I recalled shouting at someone and being involved in a light. There was also something about an animal, but what it was I couldn’t recollect. What did stay with me afterwards was the despairing knowledge that one leads a double – each part hermetically scaled off from the other.

Half of the planet’s population lives in cites, yet they consume 75% of the world’s resources and create most of its pollution. This means that all governments are going to have to create effective recycling plans. In cities where recycling schemes have been successful, it is possible to recycle 95% of all household waste. It takes 30 – 40% less energy to make paper from recycled materials than it does to make it from trees. Statistics show that there is a growing awareness of the importance of recycling, and countries such as Sweden already recycle much of their waste.
As the burning of fossil fuel is a major cause of pollution we will have to turn to other energy sources and what could be a better source than the sun? Solar energy is getting cheaper and can produce power even in cloudy conditions. The Japanese have already developed solar-electric roof tiles which are going to make entire buildings self-sufficient, greatly cutting down the need for fossil fuel.
71. Who consumes 75% of the world’s resources?
A. people living in the country.
B. people who recycle.
C. 50% of the world’s population.
D. the Asians.

A. It needs less energy to produce it.
B. It is better quality
C. It is of less value.
D. It comes from household waste.
73. What is a major source of pollution?
A. solar energy.
B. fossil fuel burning.

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.
Earth is richly supplied with different types of living organisms which co-exist in their environments, forming complex, interrelated communities. Living organisms depend on one another for nutrients, shelter, and other benefits. The extinction of one species can set off a chain reaction that affects many other species, particularly if the loss occurs near the bottom of the food chain. For example, the extinction of a particular insect or plant might seem inconsequential. However, there may be fish or small animals that depend on that resource for foodstuffs. The loss can threaten the survival of these creatures and larger predators that prey upon them. Extinction can have a ripple effect that spreads throughout nature.
In addition to its biological consequences, extinction poses a moral dilemma for humans, the only species capable of saving the others. The presence of humans on the planet has affected all other life forms, particularly plants and animals. Human lifestyles have proven to be incompatible with the survival of some other species. Purposeful efforts have been made to eliminate animals that prey on people, livestock, crops, or pose any threat to human livelihoods. Some wild animals have been decimated by human desire for meat, hides, fur, or other body parts with commercial value. Likewise, demand for land, water, and other natural resources has left many wild plants and animals with little to no suitable habitat. Humans have also affected nature by introducing non-native species to local areas and producing pollutants having a negative impact on the environment. The combination of these human-related effects and natural obstacles such as disease or low birthrates has proven to be too much for some species to overcome. They have no chance of survival without human help.
As a result, societies have difficult choices to make about the amount of effort and money they are willing to spend to save imperiled species. Will people accept limits on their property rights, recreational activities, and means of livelihood to save a plant or an animal? Should saving such popular species as whales and dolphins take priority over saving obscure, annoying, or fearful species? Is it the responsibility of humans to save every kind of life form from disappearing, or is extinction an inevitable part of nature, in which the strong survive and the weak perish? These are some difficult questions that people face as they ponder the fate of other species living on this planet.
What does the passage mainly discuss?
A. Humans and endangered species
B. The importance of living organisms
C. Measures to protect endangered species
D. Causes of animal extinction
