　　The Development of Rubber

　　Here is the story of rubber.From the earliest time it was common knowledge      (51) the Peruvians that when a cut was made in the outside skin of a rubber tree , a white dliquid       (52) milk came out ,and that        (53) this a sticky(粘的)mass of rubber might be made .This rubber is soft when warm,so that it is possible to give it any        (54).The Peruvians made the      (55) that it was very good for keeping out the wet. Then in the early 1800's ,the Americans made use of it for the first time .First they made overshoes to            (56) their feet dry.Then came a certain Mr.Mackintosh,who made coats of cloth covered with natural rubber.From that day to this we have been coating cloth with rubber as Mr. Mackintosh     (57),and our raincoats are still named after him.

　　But these first rubber overshoes and raincoats were all soft and sticky in summer,and     (58)and inelastic(无弹性的)in the winter when it was cold.But the rubber we have today is soft and elastic(有弹性的),      (59)very strong-even in the warmest summer and the coldest winter.This was made           (60)by a man called Goodyear.After many       (61),he found that nitric acid(销酸)made the rubber much better,but it is not hard and strong enough.Then a strange thing took      (62).A friend of his ,Nicholas Hayward,had the idea in his sleep that rubber might be made hard and strong if mixed with sulphur(硫磺)and put in the sun.Goodyear put this idea      (63)the test,and saw that it did have more or less the desired effect- though somewhat less than more. The only effect it had was on the outside of the drubber.It is common knowledge now that                                               the      (64)to make rubber hard and strong is by heating dit with sulphur.It took Goodyear four more years to find this method.When at last he did it,he had     (65)at all .Everything of the smallest value had been used to get money,even his sons'school-books.
