阅读课文《新型玻璃》理解。

     另一种“夹丝玻璃”不是用来防盗的。它非常坚硬，受到猛击仍没有一点儿损坏，即使被打碎了，碎片仍然藕断丝连地粘在一起，不会伤人。有些国家规定，高层建筑必须采用这种安全可靠的玻璃。

    Once Effendi had a joke with the Prime Minister(宰相). He said that the Minister would die the next day. The next day, the Minister fell on to the ground from a horse and really died. When the king learned this, he got angry and sent his men to catch Effendi at once.

    When Effendi was brought to him, the king shouted angrily, "Effendi, since you knew when my Minister would die, you must know the date of your own death. Say it out, or you'll die today."

    Effendi looked at the king for a while. Then he answered, "But how can I know? I'll die two days earlier than you." The king was afraid that if he killed Effendi, he himself would die after that. He thought he must keep Effendi alive as long as possible, so he let Effendi go.
