A．There was crystal in all glass.
B．Lead crystal makes good glass.
C．Crystal is as hard as skyscraper.
D．In ordinary glass, the atoms are ordered.
参考答案
正确答案：B
解析：本题答案在这句话中，“What it (lead)does is to make a very good quality glass．”因为前面有问题作为铺垫，找到B项并不难。C项和D项也比较好排除，关键是A项，“I thought．．．”结构往往用来引出以前的错误观点，不熟悉这种用法，就无法正确理解“I always thought there was crystal in glass．”
