Do you still get free plastic bags from the supermarkets? Things have changed.

China has banned free plastic bags at shops and supermarkets, and people have to pay for using plastic bags.The rule started on June 1. It came because our country tried to make litter less、 Making super—thin plastic bags has also been banned.

The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are not easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shopping.

What kind of shopping bag is the best to bring? Some students in Chongqing have a good idea. They make their own shopping bags. They use old clothes to make cloth bags, and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment.

第4题：

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 frown 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.
?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

答案：C

解析：

根据第四段“Nor was PVC，the plastic which had been used for bottles since the l960s，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。
