孙中山遗嘱中有：“积四十年之经验，深知欲达目的，必须唤起民众及联合世界上以平等待

阅读理解 。

     Mr. Grey liked shooting very much, but he did not get much practice at shooting wild animals, and

he   was not very good at it.   One of his troubles was that his eyes were not very good and he had to

wear glasses. When it rained and his glasses got wet, he could not see very well.

     One day he was invited to go out shooting bears in the mountains. It was rather a rainy day and by

mistake Mr. Grey shot at one of the other hunters and hit him in the leg.

     There was a court case (官司) about this, and at it the lawyer(律师) for the other man said, " Why

did you shoot at Mr. Robinson?"

     Mr. Grey answered, "I thought that he was a bear."

     "When did you realize (意识到) that you were wrong?" the lawyer asked.

     "When the bear began to shoot back at me," Mr. Grey answered.
