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.

Polyester bottles are virtually unbreakable. The manufacturers claim they are also lighter, less noisy when being handled, and can be reused. 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.

题目解答

答案

正确答案： C

您的答案：

本题解析：

根据第四段“Nor was PVC，the plastic which had been used for bottles since the 1960s．suitable for drinks with gas in them．"可知，作为“plastics of various kinds”中的一种，PVC在1960s就已用于瓶子包装，因此可以判断“plastics of various kinds”在1960s就已用于瓶子包装。

解析

本题考查学生对文章细节信息的捕捉能力，特别是对时间表达和上下文逻辑关系的把握。关键点在于理解“plastics of various kinds”具体指代的内容，以及它们被使用的时间和适用范围。需要结合上下文，明确PVC塑料的历史应用及其局限性。

第16题

定位关键句：
第四段中提到：“Nor was PVC, the plastic which had been used for bottles since the 1960s, suitable for drinks with gas in them.”

  • 核心信息：PVC塑料自1960年代开始被用于制作瓶子，但不适合装含气的饮料。
  • 选项分析：
    • C选项“since the 1960s but not for liquids with gas in them”直接对应上述信息，时间点和否定条件均匹配。
    • 其他选项的时间点（如1970s、1982）或适用范围（如“large bottles”）与原文不符。

结论：正确答案为C，因为PVC塑料自1960年代起被用于瓶子，但无法用于含气液体。
