【专家解说】： Nowadays, energy can be obtained through various sources such as oil, coal, natural gas, solar heat, wind, etc. But the conventional energy like oil, coals are being used up rapidly, and solar heat can't become widely used immediately for technological reason. In my opinion, unclear energy will take the place of conventional energy, because people now can control this energy freely, and unclear energy is non-polluting, inexhaustible, and it's much safer than coal and oil. Coal and oil are burned, they also produce many harmful gases, and the air has been seriously polluted by such gases, which will threaten people's living environment. And many accident happened because of the wrong use of such energies.
However, such things can't happen when we use nuclear energy, Though when the nuclear leaks out, it will do great harm to people' s health and the environment. We can do enough work to avoid such things, and limited such things at a low percentage.
I believe if we use the nuclear energy in the right way, it will provide us enough energy without doing any harm to us.
