 The word “plastic” comes from the Greek word “platicos” and is used to describe     1     that can be easily shaped.

    The history of plastic is longer than you might     2    . In fact —    3     man-made plastic ever to appear

on the market was made over a hundred years ago. It was called “celluloid(赛璐珞)." It was discovered by both an Englishman and an American in the same year.     4     it was the Americans who first produced it on a large scale during the year 1860. Everybody was     5     by this new material which could he molded(用模子做) into shapes and     6     so cheap to Buy.

    Poor young men     7     in cities with lots of smoke and dirt were     8     to buy white celluloid collars(领子) collars were hard and uncomfortable. But they did not have to be sent to wash. The poor young men     9     rub them clean every evening with soap and water! Poor mothers.     10     had not been able to afford playthings     11     their children, were now able to buy them playthings —    12     of celluloid. But celluloid had one very serious fault. It caught fire very easily. In fact it burned even more quickly than wood or cloth. There were many terrible accidents, particularly     13     children. For years scientists worked hard to find a better plastic material than celluloid. I'hey had     14     success. Then in 1932, an American scientist called Baekeland produced a hard plastic material which did not burn.     15     became known     16     Bakelite(*醛塑料). Other plastic materials like Bakelite were     17     produced. They     18     to make electrical fittings, plates and cups. Poor people liked them because they were both cheap and rich people     19     them because they were cheap,and because they could only he made     20     dark colours.

解析：1.这句话表示plastic这个单词来源于希腊语platicos,而且被用来描述容易成形的东西。 2.塑料的历史要比你可能想到的历史长。 3.这里表示最早的、最先的。 4.这里表示虽然英美两国同年发现,但是美国人率先生产。 excited by,"因为......而激动”。 6.它的主语是which,而which指的是this new material, 所以用单数。 ing in cities是现在分词短语作后置定语,这里指的是在城市里工作的贫穷的年轻人。 able to表示“能够” d表示“能够”。 10.这是一个非限定*定语从句,who指的是前边提到的poor mothers, 在非限定*定语从句中作主语。 11.表示“为”,在这里指的是那些贫穷的母亲给孩子们买不起玩具。 of表示“由……制成”。 g children表示“在孩子们当中”。 le success表示“没有成功”。 指的是前面所提到的a hard plastic material。 known as“作为 而著名”。 表示“也”,这甩表示其他的塑料材料也被制造了出来。 used表示“被用来 ”。 ike表示“不喜欢”,这里表示富人们不喜欢塑料制品。 dark colours这里表示“深*,黑*”。
