Question

Poor young men _7_in cities with lots of smoke and dirt were_8_ to buy white celluloid collars(领子).The 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. They 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(酚醛塑料).Other plastic materials like bakelite were _17_ produced.
