M: Now that you are all here, let me show you around this plant, and if you listen closely, you might learn something about glass and crystal.
W: I had nothing about the structure of crystal before I have just learned in our science class. I always thought there was crystal in glass.
M: Well, real crystal is generally a hard substance in which the atoms are arranged in a highly ordered structure much like the framework of a skyscraper.
W: Does that mean in ordinary glass the molecules are not ordered?
M: That’s right, but most of the glass made here is actually lead crystal or glass with a high lead content.
W: Lead? Isn’ t lead poisonous?
M: What it does is to make a very good quality glass. You will see several samples of glass on the tour. If everyone is ready now, please follow me.
W: I am supposed to hand in a paper in this aspect after the tour.
选项 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.
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．”
