Transparent animals let light pass through their bodies the same way light passes through a window. These animals typically live between 

the surface of the ocean and a depth of about 3,300 feet—as far as most light can reach. Most of them are extremely delicate and can be 

damaged by a simple touch. Sonke  Johnsen, a scientist in biology, says, “These animals live through their life alone. They never

touch anything unless they're eating it, or unless something is eating them.”

And they are as clear as glass. How does an animal become see-through? It's trickier than you might think.

      The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and

 scatter(散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption

 make an object look different from other objects around it, so you can see it easily.

But a transparent object doesn't absorb or scatter light, at least not very much, Light can pass through it without bending or stopping.

That means a transparent object doesn't look very different from the surrounding air or water. You don't see it —you see the things

behind it.

   To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they

contain pigments(色素) that absorb specific colors of light. But a transparent animal doesn't have pigments, so its tissues won't absorb

 light. According to  Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.

Animals are built of many different materials—skin, fat, and more—and light moves through each at a different speed. Every time light

moves into a material with a new speed, it bends and scatters.Transparent animals use different tricks to fight scattering. Some animals are

simply very small or extremely flat. Without much tissue to scatter light, it is easier to be see--through. Others build a large, clear mass of

 non-living jelly-lie(果冻状的)material and spread themselves over it .

    Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light 

exactly as much as water does. They need to look uniform. But how they're doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.

    We face problems in our everyday life.{#blank#}1{#/blank#}Don't worry.As long as you are breathing,you can solve problems.

Be aware of problem

    First of all,it is important to know and understand the problem clearly.{#blank#}2{#/blank#}.Following questions like why,what, how,when,where and who will take you to the root cause of the problem.

Analyze the problem

    Analyzing the problem will give you time to think of a proper solution.{#blank#}3{#/blank#}.They can be diagrams（图表）, flowcharts or a lists,etc.

Plan a strategy（策略）

    Planning a strategy will help you waste less energy and time in attempting all the solutions.This step includes knowing the advantages and disadvantages of applying a solution.In this way,you can abandon the strategy that you don't find worthy to apply.

{#blank#}4{#/blank#}

    Leave out the information that is not required for the solving of the problem.You need to be accurate with the details.Keeping the unrelated information can sometimes complicate the simple problems as we tend to overlook the important information.

Carry out the solution

    Putting the solution into effect in a correct way to get the result expected is important while solving a problem. You need to be creative while actualizing（实施）a solution just in case some other problem arises while applying the solution.{#blank#}5{#/blank#}

A.Remove unrelated information.

B.You can use various tools to study the problem.

C.Use yes or no questions to get better information.

D.Knowing the problem means solving half the problem itself.

E.They can be social problems,relationship problems,or problems at work.

F.Being ready with alternatives is also important in case a solution works only half way.

G.Spend 10% of the time analyzing the problem and 90% on the solution,not the opposite.

    Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO( United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.

    Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.

    It's Jason Moran's job to help change that. As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.

    ＂Jazz seems like it's not really a part of the American appetite,＂ Moran tells National Public Radio's reporter Neal Conan. ＂What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and write anymore. It's actually color, and it's actually digital.＂

    Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. ＂The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,＂ says Moran.

    Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, ＂just to kind of put it back in the mind that Waller is dance music as much as it is concert music,＂ says Moran. ＂For me, it's the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context,＂ says Moran, ＂so I want to continue those dialogues. Those are the things I want to foster.＂

    BEIJING (News Agency) — Children in China today spend five times more money than their parents did when they were young.

    So what are all these children buying? The list is long: iPads, cell phones and jeans are typical items that children “have to” buy. And they will do anything to get them. They ask their parents over and over until they buy them.

    But parents also need to take the blame(责备) for spending so much money. They want their children to have the best things. They end up competing with other parents over whether their children have the latest products.

    So it's no wonder children find it hard to learn the importance of saving money rather than spending it all the time.

    And it's hard to save when companies use advertising (打广告)and clever slogans (口号) to encourage young people to buy their products. They even encourage children to keep asking their parents for something until they get it.

    Today, you don't even need to have money in order to buy something. Banks give out credit cards and loans (贷款) all the time, so people are saving less and less. We are used to carrying lots of money around. And if you don't have much, you can always borrow some.

    But this hasn't always been the case. When our grandparents were young, there was very little money and everyone had to save hard for things they bought. They only bought things they needed, not things they just wanted.

    The older generation made the wise expression, “Money doesn't grow on trees.” This is as true now as it was 50 years ago. They give money a great deal of value. And we all have a lot to learn from them.

    I used to be crazy about the hunting season. The excitement of waiting for a prey(猎物)and the pride of showing off the kill fascinated me. However, everything changed after that cold morning.

    Early on that day of the late fall, I set off alone for the woods, packing a gun, a bottle of hot coffee and three thick sandwiches. After finding the fresh deer's tracks in the snow, I settled down behind a little bush.

I sat there for about an hour. It was then that I saw him. A deer, a big beautiful deer! There was no cover nearer to him than 30 yards. Surely I couldn't miss! I waited for him to realize I was there. I waited for him to be shocked and run away. But he fooled me completely. He came towards me! He was curious, I suppose, or maybe he was stupid—how else can you explain it? Well, that deer walked right up to where I was sitting. Then he stopped and looked at me!

    What happened next is hard to believe, but it's true. And it all seemed quite natural. Just as when a friendly young deer comes near you, I reached up and scratched his head. And he liked to be scratched. In fact, he practically asked for more. Then, I fed him my sandwich! Yes, I know what a deer eats, but that deer ate my sandwich. Well, he finally went his way, down the hill and up the deer trail. Shoot him? Not me. You wouldn't have either, not after that. I just watched him go.

    When I was about half way back, I heard two shots, followed by a dull slam(撞击)a few seconds later. Those two shots usually mean a kill. I had forgotten there were other hunters that day.

    Those hunters would never know they could have scratched his head.
