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 levels 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. Which of the following statements is true?
| A．Nuclear radiation is just like common radio waves. |
| B．Nuclear radiation can cause cancer to human beings. |
| C．Nuclear radiation can be detected by human senses. |
| D．Nuclear radiation can be safe to human beings if its level is low. |
How can nuclear radiation kill an animal?
| A．By damaging its heart. | B．By killing a few cells. |
| C．By hitting any place in its body. | D．By killing many cells in important organs. |
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 |
If you plan on visiting to Fiji, you are probably looking for some fun things to do. Below are four unusual places.
The Poseidon Resort
The Poseidon resort is an underwater resort that gives visitors a beautiful view of sea life. This resort covers 255 acres. It’s covered and surrounded by a lagoon (咸水湖) that covers 5,000 acres and is about 90 feet under water, giving you a beautiful view of sea life righ

As we all know, any country has good reasons to want its citizens to be as healthy as possible. This led to the introduction of a health service in many countries. France has developed into a country in which all citizens can get most of the health treatment free. The money for this is partly from the people who are willing to offer.
But there are different opinions about the Health Service. The number of patients treated every year and the cost of treatment are much greater than expected. This means that the people who work for the Health Service --- doctors, nurses and other hospital workers, have much more work to do, and as a result they have little time for preventive treatment.
However, the tough problem is that as many people are able to receive treatment more expensive than they can pay, sometimes people go and visit their doctors when they don’t really need to. As there are many patients, doctors cannot spend time long enough with each patient. So some people prefer to pay for their own treatment so that their doctors can examine them more carefully. In fact, some rich people feel that they should pay more free money, which would be given to other citizens. France is described as an example to show that __________.
| A．people have to pay part of the medical care |
| B．everyone in France enjoys free medical care |
| C．it is a country with the Health Service |
| D．it is a very rich country in Europe |
What is the problem in the Health Service?
| A．Money is not enough to employ more medical workers. |
| B．There are not enough well-treated doctors. |
| C．People can get more preventive treatment. |
| D．Doctors and nurses are not working hard. |
Why do many people go and see the doctors even when they really don’t need to?
| A．To keep himself even more healthy. | B．To receive treatment free of charge. |
| C．To take back some expensive medicine. | D．To get necessary protective treatment. |
What can we infer from the last paragraph?
| A．The Health Service is quite successful so far. |
| B．People should not go to the doctors unless necessary. |
| C．There is much to improve the Health Service. |
| D．The rich should be allowed to pay for the treatment. |
In many countries today, laws protect wildlife. In India, the need for such protection was realized centuries ago.
About 300 B.C. an Indian writer described forest that were somewhat like national parks today. The killing of game beasts was carefully supervised(监视). Some animals were fully protected．Within the forest, nobody was allowed to cut timber(wood for building), burn wood for charcoal(炭), or catch animals for their furs. Animals that became dangerous to human visitors were caught or killed outside the park so that other animals would not become uneasy.
The need for wildlife protection is greater now than ever before. About a thousand species of animals are in danger of extinction, and the rate of extinction was about one species every fifty years from A.D. 1 to 1800, but now it is about one species every year. Everywhere, men are trying to solve the problem of protecting wildlife caring for the rapid growth of the world’s population. In forest of ancient India __________.
| A．people were permitted to hunt for fun |
| B．only few kinds of animals could be killed |
| C．the killing of game beasts was strictly limited |
| D．no killing of beasts was allowed． |
Dangerous animals were caught or killed outside the park so as to __________.
| A．keep human visitors safe | B．free the rest of the animals from worry or fear |
| C．both A and B | D．supply other animals with more food |
The underlined word “extinction” probably means __________.
| A．being hungry | B．dying out | C．growing slowly | D．being killed |
The example of man’s connection with wildlife protection can date back to _______.
A. the third century B. more than 2000 years ago
C. A. D. 1 to 1800D. over 300 years ago
As prices and building costs keep rising, the “do-it-yourself”（DIY）trend in the US continues to grow.
“We needed furniture for our living room,” says John Ross, “and we just didn’t have enough money to buy it. So we decided to try making a few tables and chairs.” John got married six months ago, and like many young people these days, they are struggling to make a home at a time when the cost of living is very high. The Roses took a 2-week course for $280 at a night school. Now they build all their furniture and make repairs around the house.
Jim Hatfield has three boys and his wife died. He has a full-time job at home as well as in a shoe making factory. Last month, he received a car repair bill for $520. “I was deeply upset about it. Now I have finished a car repair course, I should be able to fix the car by myself.”
John and Jim are not unusual people. Most families in the country are doing everything they can to save money so they can fight the high cost of living.
