Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them or sense them without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated(辐射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its parents.
Radiation can hurt us. We must know the truth.

There are three separate sources of danger in supplying energy by nuclear power.
First, the radioactive material must travel from its form of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even though, heavily populated areas.
Secondly, there is the problem of waste. All nuclear power stations produce waste that in most cases will remain radioactive for thousands of years. It is impossible to make these waste radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.
Third, there may occur the danger of a leak or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.
Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster is extremely high.
1.Which of the following is FALSE ?
A.It is possible that a leak or an explosion occurs at a power station. |
B.It is unusual for radioactive materials to be transported across land. |
C.The containers are likely to be broken by an earthquake. |
D.Nuclear wastes remain dangerous in most cases for many years. |
2.The author thinks that the ways to store nuclear wastes are ____________.
A.easy | B.impossible | C.reasonable | D.ineffective |
3.What do we learn from the last paragraph ?
A.The power station is a safe place. |
B.The dangers of nuclear energy can be prepared. |
C.The general public are strongly against the nuclear program. |
D.Itself, none of the three dangers is very likely to cause much worry. |
4. What is this passage mainly about ?
A.uses of nuclear power |
B.Dangers from nuclear power |
C.Public anger at nuclear power |
D.Accidents caused by nuclear power. |

There are three separate sources of danger in supplying energy by nuclear power.
First, the radioactive (有放射性的) material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas.
Second, there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes non-radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.
Third, there may occur the danger of a leak (泄漏) or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection (不赞成,反对) to the nuclear program. However, it can happen.
Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster is extremely high.
1.Which of the following is not true?
A.It is likely that a leak or an explosion occurs at a power station.
B.It is not usual for radioactive materials to be conveyed across land.
C.The containers are likely to be broken by an earthquake.
D.Nuclear wastes remain risky in most cases for many years.
2.The author thinks that the ways to store nuclear wastes are __________.
A.easy B.impossible
C.reasonable D.ineffective
3.What do we learn from the last paragraph?
A.The power station is a place that frees from danger.
B.The dangers of nuclear energy could be prevented.
C.The general public are opposed to the nuclear program.
D.By itself, none of the three dangers is very likely to lead to much worry.
4.What is this passage about?
A.Uses of nuclear power.
B.Dangers from nuclear power.
C.Public anger at nuclear power.
D.Accidents caused by nuclear power.
