Nuclear power's danger to health, safety, and even life itself can be described in one word; radiation(辐射).
Nuclear radiation has a certain mystery about it, partly because it cannot be detected (探测) 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 completely by killing masses of cells in important organs (器官). 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 significant. This is the case when only a few cells are hit, and if they are killed completely. 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 reproduce themselves in an unusual way. 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 knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth. According to the passage, the danger of nuclear power lies in ________
__.
A.nuclear mystery | B.radiation detection |
C.radiation level | D.nuclear radiation |

A.kill large numbers of cells in main organs so as to cause death immediately |
B.damage cells which may grow into cancer years later |
C.affect the healthy growth of our younger generation |

Which of the following can be best inferred from the passage?
A.The importance of protection from radiation can be overemphasized (过分强调). |
B.The mystery about radiation remains unsolved. |
C.Cancer is mainly caused by radiation. |
D.Radiation can hurt those who do not know about its danger. |
Most respected scientists agree that we need to find another source of energy- and quickly. If we continue to burn oil and pump carbon into the atmosphere, then the effects on global climate will lead to global disasters even before the oil disappear.
The British government has set a target of a 20 percent reduction in carbon emission by 2010. Central to this policy is the search for alternative, renewable forms of energy production---and this is where the serious disagreement among scientists begins.
Here, two people active in the debate about wind farms give their points of view.
Simon Shearman
“First, a few facts about wind power. Wind is one of the cheapest of the new, renewable forms of energy. It is extremely safe---no member of the public has ever been injured at a wind farm. The shallow waters around Britain are the windiest in Europe---ideal locations for wind farms and, by 2010, up to ten percent of the electricity used in the UK could be produced by wind power. I find it annoying and frustrating that the biggest objection that opponents of wind farms can come up with is that the crisis of global warming is real and something must be done urgently.”
Alice Evans
“The simple, obvious fact is that wind turbines(涡轮机) cannot generate electricity if the wind is too light or too strong and it often is. Many scientists estimate that wind turbines generally produce only 30 percent of their capacity(容量). This is not a reliable enough supply to enable us to close down conventional power stations. In fact, wind power can’t keep up with the growth of the demand for electricity, let alone replace other sources of power.”
It’s a topic that is causing heated debate around the country---but one we must address before it’s too late---before the oil runs out.Many scientists have different opinions on the search for a renewable energy because ______.
A.they think fossil fuels are everlasting. |
B.British government’s target is not realistic. |
C.they are not sure in finding the clean and renewable energy. |
D.the technology is not advanced enough. |
We can learn from the passage that ______.
A.there won’t be a global disaster before the world runs out of oil. |
B.the British government wants people to use 20 percent less oil by 2010. |
C.Alice Evans supports the idea of wind power. |
D.Simon Shearman thinks Britain a particularly suitable place for wind farms. |
If we generate electricity with wind turbines, _______.
A.a light wind will do. |
B.we cannot make full use of the capacity. |
C.a strong wind will do |
D.we’ll have enough electricity. |
What can we learn from the last paragraph?
A.Wind power is a good solution to energy crisis. |
B.We’re experiencing the oil crisis now. |
C.We should find alternative energy for oil as soon as possible. |
D.There is no need for us to worry about energy problem. |
Technology is creating big changes in the music industry. Music lovers listen to and buy music on the Internet. They can watch live concerts of favorite artists online. And music makers, as well as music industry officials, use social media(媒体) to reach an increase public interest.
Nick Sherwin is the founder of the band called Suburban Skies. He says today’s technology permits a band to control its own future. He said, “Social media is a wonderful thing. You can make use of it to reach the public.” Sherwin says the Internet and social media have created possibilities for musicians. He says the new way to success is to give visitors more than one type of experience. “The most important thing is the content. You have to have songs and videos to show the audience. But I think it is extremely important to do shows, to build your brand, and to make you well known, ” Sherwin said.
Music industry officials discussed the future of the business during an international conference in Los Angeles, California. They said musicians are choosing to perform live across the country, following the drop in CD sales in the Unites States. Rob Light is head of music with a creative artists agency. He said, “Most of the income for artists is now coming from the live marketplace.”
Along with the popularity of live music there has been a big increase in the number of music festivals. These events are advertised on social media. Pasquale Rotella leads Insomniac, a company that produces electronic dance music festivals in several countries. “Someone could make it in their bedroom and put it out there. People can gain fans online without anyone’s help. That has completely helped the growth of dance music. ” said Rotella.
Bob Pittman leads the radio organization — Clear Channel Communication. He says music lovers are still listening to the radio, although there are new ways of finding music. He says 70 percent of Americans say they discover new music from what they hear on the radio. But Rob Light says radio will soon be a thing of the past. However, Nick Sherwin is not worried. He just wants to reach everyone who likes his style of music with the help of the Internet.From Paragraph 2, we learn that Nick Sherwin ______.
A.doesn’t have any good ways to reach the public. |
B.doesn’t believe his band has good content to draw attention. |

No one can believe that the over 6 300-kilometer long Great Wall might disappear some day. Believe it or not, the Great Wall is being destroyed by people. Less than 20 percent of the Great Wall built in the Ming Dynasty is still perfect, but about 80 percent is in danger. The Great Wall can be called “great” mostly because of its amazing length. But we should realize that the length was made up of one brick at a time. If we do nothing to save the Great Wall, it will become a series of separate wasteland rather than a historic site.
The Great Wall is actually a series of walls built and rebuilt by different dynasties over the past 2 000 years. It began in the rule of China’s first emperor, Qin Shihuang of the Qin Dynasty (221 BC~206 BC),and lasted into the Ming Dynasty. The parts built before the Ming Dynasty have nearly disappeared. People are familiar with sections such as Badaling in Beijing and Jiayuguan Pass in Gansu because they have been open to tourists for many years. But those sections far away from the public eyes have been almost forgotten.
Few local people knew the 3-meter-high walls made of earth and stones beside them are part of the Great Wall.The lack of knowledge is considered as one of the main reasons behind human.
The bricks on the Great Wall are carried off by countryside people to build their houses, sheep corral(畜栏) and pigsties(猪圈).Some were taken away to build roads. Bricks carved with people’s names are put away as remembrance. Rubbish is spread over the battlements(城垛).The bricks can be sold for 15 yuan per tractor load. Those who destroyed and are destroying the Great Wall know its name, but are not clear about its cultural meaning. It will take a long time to let them know this. The local farmers not only carried off the body of the Wall but dug out the entire base.
It is necessary to protect the Great Wall. First of all, the officials should be aware of the importance of the Great Wall. Young Chinese should know more about the nation’s great civilization (文明)and learn to love it.The main reason for which the Great Wall can be called “great” is__________.
A.it was made by brick | B.it was very wide |
C.it was very long | D.it had a long history |
Why does the author say the Great Wall might disappear?
A.It is useless from now on. |
B.It will be replaced by a new one. |
C.Some parts of it are being destroyed. |
D.It’s too old to be used again. |
The underlined part “those sections far away from the public eyes” refers to the parts of the Great Wall__________.
A.that are too difficult to understand |
B.nobody can watch |
C.that are too far to been seen |
D.that are not well known to the public |
What’s the main reason of the Great Wall’s being destroyed?
A.The local people are short of culture knowledge. |
B.The local people need bricks and stones to build houses. |
C.The local people think that the Great Wall is not important. |
