　　A

　　Niels Bohr did well at school without ever being brilliant, usually coming third or fourth in a class of about 20 students. If he really was good at any subject, it was, perhaps, physical education. He was an excellent soccer player, yet not as good as his brother. This was Niels Bohr, the world­famous Nobel prize winning physicist.

　　Born to a physiology (生理学) professor, Niels lived in a world of ideas and discussion from his very early childhood at home. He developed an interest in physics and mathematics from the early days of his education. With no laboratory available in school and college, he would perform experiments in his father's laboratory. His first work on surface tension was done here, for which he won the Gold Medal in 1906 from the Royal Danish Academy of Sciences.

　　Early in his scientific career, Bohr made great contributions to the understanding of atomic (原子的) structure based on quantum mechanics (量子力学)．Neils Bohr came up with the model of an atom which was able to explain all the properties (性质) of the atom. It is this atomic model that is accepted even today with only very slight improvements. This work won him the Nobel Prize for Physics in 1922.

　　When the Nazis controlled Denmark, his life became difficult. He had to escape to Sweden in 1943 in a fishing boat; from there he fled to England. England opened up opportunities of working on the atom bomb (原子弹)．After a few months he joined a British research team and went to Los Alamos in the United States where the team continued to work on the project.

　　Niels was also deeply concerned with making people realize the destructive power of the atomic bomb. He published a letter to the United Nations in 1950 which asked them to help get rid of nuclear (核的) weapons in the world. This and his other activities won Bohr the first U．S. Atoms for Peace Award in 1957. He spent his remaining years showing people that nuclear energy must be used in a positive and productive way.
