Isaac Newton, the great British scientist, is often so deep in his thoughts that he will forget to eat his dinner.
One day his friend came to have dinner with him. Dinner was put on the table but Newton didn't come out of his study（书房）. His friend sat down and waited for him. After waiting for quite a long time, he decided that Newton must be so deep in some new theory that he forgot all about the dinner. So he began to eat the chicken without Newton.
When he finished, he thought he would play a joke on his friend. He put all the chicken bones（骨头）back on the dish and covered them with the dish over. Then he left Newton's house. He was quite certain that his joke would work.
Several hours later, Newton came out of his study, feeling very hungry. He saw the table was ready for dinner and so he sat down. When he lifted the cover and saw the bones of the chicken, he was greatly surprised. He turned, looked at the clock, and saw that it was long past his usual time for dinner.
"Well, well," he said to himself, "I thought I ate nothing, but I am wrong." He got up from table and went back to his study and began to work again.
