书店运来一种故事书，第一天卖出30%，第二天卖出50%，第二天比第一天多卖了60本．书店运来的故事书一共有多少本？

Two elderly women in my community died "full of years,"which means both died from the normal wearing out of the body after a long and full life. Their homes happened to be near each other, so I paid visits to the two families.

The son of one of the deceased(已故的) women said to me,"If only I had sent my mother to Florida and got her out of this cold ,she would be alive today. "The son of the other deceased woman said, "If only I hadn't insisted on my mother's going to Florida, she would be alive today. That long airplane ride, the sudden change of climate, was more than she could take. "

When things don't turn out as we would like them to, it is very likely for us to think that if we had done things differently, the story would have had a happier ending. Any time there is a death, the survivors will feel guilty.

There seem to be two elements in our readiness to feel guilty. The first is our pressing need to believe that the world makes sense and that there is a cause for every effect and a reason for everything that happens. That leads us to try to find the patterns and connections.

The second element is the notion(观念)that we are the cause of what happens, especially the bad things that happen. Psychologists trace this feeling back to our childhood. A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. The world works for him. When he cries, someone comes to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely outgrow the notion that our wishes cause things to happen.
