Plastics is the term commonly used to describe a wide range of synthetic or semi-
synthetic materials that are used in a huge and growing range of applications. Everywhere
you look, you will find plastics. We use plastic products to help make our lives cleaner,
easier, safer and more enjoyable. We find plastics in the clothes we wear, the houses we live
in, and the cars we travel in. The toys we play with, the televisions we watch, the computers
we use and the DVDs we watch all contain plastics.
Plastics are organic materials, just like wood, paper or wool. The raw materials used to
produce plastics are natural products such as cellulose, coal, natural gas, salt and, of course,
crude oil. Plastics have become the modern material of choice because they make it possible
to balance today’s needs with environmental concerns.
The term “plastic” is derived from the Greek word “plastikos”, meaning fit for moulding.
This refers to the material’s malleability, or plasticity during manufacture, which allows it to be
cast, pressed, or extruded into a variety of shapes - such as films, fibres, plates, tubes,
bottles, boxes, and much more.

Polyester is now being used for bottles. ICI, the chemicals and plastics company, believes that it is now beginning to break the grip of glass on the bottle 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 world-wide for the last few years. Between 1982 and 1984 the Plastics Division of ICI had lost a hundred and twenty million dollars, and they felt that the most hopeful new market was in packaging, bottles and cans.
Since 1982 it has opened three 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 drinks companies : like Coca Cola started selling their drinks in grant two-litre containers. Because of the build-up of 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 be 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, 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 public, though, have been more difficult to persuade. ICI’s commercial department is developing different 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.
1.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 companies like Coca Cola first tried them.
2. 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.
3. 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.
4. 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.
5. Plastic containers for holding food in the same way as cans
A. have been used for many years.
B. are an idea that interests the plastics companies.
C. are possible, but only for hot food.
D. are the first things being made in the new factories.

VII - 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.
Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.
First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.
Second, we need to watch the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.
Third, we need to reduce waste. We need to recycle whenever possible, but shouldalso try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.
If we do our part in our own homes, we can help keep the planet from becoming more polluted.
44, The average person produces every day _______.
A. three point four pounds of waste B. thirty four pounds of waste
C. four point three pounds of waste D. forty three pounds of waste
45, If we do our part in our own homes, we can help keep ______.
A. the planet from becoming less polluted B. the planet from becoming more polluted
C. the house from becoming few polluted D. the planet from becoming little polluted
