A well-known manufacturer of weighing machines produced a new model.
The machine had a computer inside it, and this computer could do wonderful things: it could weigh people very accurately; it could tell them their weight in their own language; and it could tell them what they should eat to reduce their weight.
The manufacturer decided to try out his machine before he sold it to the shops.
He looked around for a good place to put it and finally decided on an airport. There were always people at an airport from many different countries.
The first person to use the machine was an Italian woman. She stood on the machine, put a coin in and waited to hear her weight.
The machine took only a second or two to weigh her, decide on her nationality and the language she spoke, and figure out what kind of food she should eat.
“Good morning, madam,” it said in perfect Italian. “Your weight is 72 kilos, three more than it should be for a woman of your height, age and nationality. This is because you have been eating too much spaghetti. I suggest you eat more fruit and vegetables. Please have a nice day”.
The second person to use the machine was a Chinese girl. She stood on the machine, put a coin in and waited to hear her weight.
“Good morning, Miss," the machine said in perfect Chinese. "Your weight is 38 kilos, exactly the correct weight for your height, age and nationality. Continue to eat what you are eating. Please have a nice day.”
The third person to use the machine was a huge Australian woman. She walked up to the machine and looked at it for a long time. At last she found the courage to stand on the machine and put a coin in. The machine spoke immediately. “Good morning. Will one of you ladies please get off?”

Nuclear radiation (核辐射)has a certain mystery, 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 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 at once by killing plenty of cells in important organs(器官). 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 when they are killed at once. 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. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.
小题1:According to the passage, the danger of nuclear power lies in       .
A.nuclear mysteryB.radiation detection
C.radiation levelD.nuclear radiation
小题2:Radiation can lead to serious trouble even at the lowest level        .   
A.when it kills a few cells
B.because the killed cells can’t be replaced
C.if it damages a few cells
D.unless the damaged cells can reproduce themselves
小题3:What does the author want to tell us?
A.Radiation can hurt us.B.Radiation is a subject scientists work on.
C.Radiation is a mystery.D.Radiation is the source of cancer.

In the computer age, most of us take a broadband Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course. You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely(稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere. Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables(光纤电缆) promise to bring extremely fast Internet connections to more users.
Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication(迹象), it may not be too long before an Internet connection simply follows you wherever you go.
小题1:The underlined part “ a catch” (in Paragraph 2) probably means “________”.
A.a rare challengeB.a desirable plan
C.an efficient deviceD.a hidden problem
小题2:What can we know from the third paragraph?
A.Internet connection has not been popular in most cities.
B.Internet service providers care about rural customers.
C.Computer is popular in developing countries.
D.It is hard to bring Internet access to users in remote areas.
小题3: Paragraph 4 mainly tells us that technological advancements ________.
A.make TV and telephone available everywhere
B.bring great change to people’s everyday life
C.make it possible for more people to use the Internet
D.bring faster Internet connections to users
小题4:What may eventually settle the “last mile” problem?
A.The broadband connection’s getting faster.
B.More and more Internet users.
C.More and more Internet connections.
D.The rapid progress in cell phone technology.

We are warned by our teachers not to waste time because time 21 will never return. I think it quite 22. What does time look 23? Nobody knows, and we can’t see it or touch it and no 24 of money can buy it. Time is abstract(抽象的), so we have to  25about it.
Time passes very quickly. Some students say they don’t have 26time to review their lessons. It is 27 they don’t know how to make use of their time. They waste it in going to theatres or playing, and 28 other useless things. Why do we study everyday? Why do we work? Why do most people 29 take buses instead of walking?

Geniuses amaze us,impress us and make us all a little jealous. How do they differ from the average person?Scientists are working hard to figure out that answer. Tune in to the National Geographic Channel to find out about the discoveries they’re making in the series My Brilliant Brain.
When Marc Yu was only two years old,he began to play the piano. After a year, he started learning pieces by Beethoven. Now he’s a world-famous concert pianist at age eight. He learns newer and more difficult pieces with ease and can identify any note he hears. He seems to be specially designed for music. In Born Genius, National Geographic looks at the science behind child prodigies (神童) to explain why some children seem to be born without limits.
Geniuses didnt come naturally to Tommy McHugh. His came only after he nearly died from bleeding in his brain. After recovering, McHugh’s head was filled with new thoughts and picture. So, he began to express them in the form of poetry and art. Now, he’s a seemingly unstoppable creative machine. Suffers of brain injury have shown that great mental ability can sometimes come from damage or disease. Accidental Genius explores this puzzling relationship.
Can normal people be trained to be geniuses? Susan Polger has shown no sign of extraordinary intelligence. Yet, during her childhood, she studied thousands of chess patterns and learned to recognize them immediately. As a result, she was able to beat skilled adult players by age 10 and can now play up to five games at the same time without even seeing the boards. Make Me a Genius examines what is takes to turn an ordinary brain into that of a genius.
If becoming a genius were easy, we’d all be done. Yet, there is much more to super intelligence than simply being born lucky. Learn more about amazing brains this month on National Geographic’s My Brilliant Brain.
