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, 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 grandparents. Radiation can hurt us. We must know the truth. 51. What is the most dangerous factor of nuclear power?

A. Amount B. Quantity C. Radiation D. Place

52. Which of the following statements is TRUE?

A. Nuclear radiation can do little harm to human beings. B. Nuclear radiation can do harm to human beings. C. Nuclear radiation can be detected by human senses. D. Nuclear radiation is just like common radio waves. 53. How can nuclear radiation kill an animal? A. By damaging its heart.

B. By killing a few cells in its body. C. By hitting any place in its body.

- 18 -

D. By killing many cells in important organs.

54. Nuclear radiation has a certain mystery because_______. A. it can do harm to a person while the victim doesn't know B. human beings learn its harmfulness

C. nuclear radiation can kill a person very easily D. human beings have no effective machine to detect nuclear radiation

55. If a human being is hit by nuclear radiation, he may _______. A. die of cancer after many years B. die immediately

C. have a child who may be born weak

D. all of the above

As an English teacher, I've been lucky enough to travel to many countries. I've seen

people celebrating everything from the arrival of new babies to

the delivery of new cars.

I've attended weddings, parties and religious celebrations in countries as far apart as

Argentina and Japan, and I've noticed that gold - the metal or the colour is almost

always part of cultural events, traditions and celebrations. From \纪念品) that people give to babies in Turkey, to the

gold stars that primary teachers stick on their students' exercise books, to the gold coffin that the \of Pop\Michael Jackson was buried in, it makes me wonder: Why do people love gold?

For some people, gola seems to be a status symbol. Indian businessman Datta Phuge loves gold so much that he's even bought a shirt made of the stuff - at a cost of $ 250,000. Datta Phuge has his reasons. He explains: \Audi or Mercedes and have big cars. I chose gold. \

For other people, gold is an investment. The price of gold generally increases over time and in European markets it reached over $ 1, 500 per ounce in 2011.

And for many people, the family heirloom（传家宝） brings together status and investment. My mother has a gold bracelet
