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.

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 from 29 to 33.

In the world today, particularly in the two most industrialized areas, North America and Europe, recycling is big news. People are talking about it, practicing it, and discovering new ways to be sensitive to the environment. Recycling means finding was to use products a second time. The motto of the recycling movement is "Reduce, Reuse, Recycle".

The first step is to reduce garbage. In stores, a shopper has to buy products in blister packs, boxes and expensive plastic wrappings. A hamburger from a fast food restaurant comes in lots of packaging. usually paper, a box, and a bag. All that packaging is wasted resources. People should try to buy things that are wrapped simply, and to reuse cups and utensils. Another way to reduce waste is to buy high-quality products. When low quality appliances break, many customers throw them away and buy new ones - a loss of more resources and more energy. For example, if a customer buys a high-quality appliance that can be easily repaired, the manufacturer receives an important message. In the same way, if a customer chooses a product with less packaging, that customer sends an important message to the manufacturers. To reduce garbage, the throwaway must stop.

The second step is to reuse. It is better to buy juices and soft drinks in returnable bottles. After customers empty the bottles, they return them to the store. The manufacturers of the drinks collect the bottles, wash them, and then fill them again. The energy that is necessary to make new bottles is saved. In some parts of the world, returning bottles for money is a common practice. In those places, the garbage dumps have relatively little glass and plastic from throwaway bottles.

The third step is being environmentally sensitive is to recycle. Spent motor oil can be cleaned and used again. Aluminum cans are expensive to make. It takes the same amount of energy to make one aluminum can as it does to run a color TV set for three hours. When people collect and recycle aluminum (for new cans), they help save one of the world's precious resources.

What are the two things mentioned as examples of recycling?

A. Aluminum cans and plastic wrappings

B. Hamburger wrappings and spent motor oil

C. Aluminum cans and spent motor oil

D. TV sets and aluminum cans

Read the passage below and decide whether the statements are TRUE or FALSE?

Earth Day is coming! Our class are going to celebrate it by making crafts from used materials in the recycle-reuse-renew lessons. We also buy some brand-new craft supplies to celebrate and learn about Earth Day. We start by looking for old things around our houses and bring them to class. Today, we learn how to make a hanging garden with plastic bottles. Large plastic bottles are turned into beautiful hanging planters in this green-living and green-thumb project. They are easy to make. All we have to do is to cut one side of the bottles so that we can put soil and plant small flowers in them. We can either bring the planters home or hang them on campus for a gorgeous hanging garden.

Question: Today their class use plastic bottles to make flower vase

A. True

B. False
