　　Passage 4

　　Directions: The passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, D. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.

　　Polyester (聚酯 ) 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 giant two-liter 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.
