【英语专业四级满分听力】原子能

  这篇听写比较浅显易懂。 Hints: 文中有两个词可能容易拼错nucleus和neutrons 注意标题不用写,直接写正文即可

  You can not see an atom, nor the electrical power within it. Yet you can see the large holes made in the earth by atomic force. You can see the power plants. You can see ships driven through the ocean by atomic power. And you can see many other things that use atomic power, for example, in space travel, in medicine and in electronics. The power in an atom comes from the center or nucleus of the atom. When an atom is divided, heat appears and very small pieces called neutrons fly away from the nucleus. When many atoms are brought together, a chain reaction happens. This causes a continuous explosion. By controlling the nuclear reaction, scientists can put the power from the heat to work. This power or energy can be used to make electricity. It can also be used to make fresh water from seawater, or to drive the engines of ships or submarines.
