I think I‟m one of the luckiest people in the world because of the time I‟m able to spend with young people who are
not afraid to show their excitement and zest for life．1, I would prefer a person with passion and enthusiasm to a person with 2and talent any day of the week．You can teach and develop skills, 3you cannot develop a love of life and an optimistic attitude．These are 4of a person and appear at all times during work or play．Furthermore, they are traits that one is born with and they will never 5them．
As a 6and an Independent Education and Career Planning Advisor, I 7too many children and young adults who are on a road to despair unless someone can find a way to change their attitude towards 8and indeed life itself!
9, society has turned out too many children and young that are unwilling to put much 10or thought into their work．Whenever I come across such people—11or ol d, I‟m reminded of a boy who went with his mother on a blueberry picking hike into the 12．The boy filled his 13mostly with moss（苔藓）and then covered the moss with a thin layer of blueberries so that it looked 14．But the next morning, he found the blueberry pie which his mother 15for him was moss．
So 16, whether you are in school or 17, if you have enthusiasm and if you are 18to put in consistent effort along with passion, you will receive the 19．If, on the other hand, you are 20and prefer to take short-cuts, you should not expect to achieve the same results．

Life in the Clear
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 any thing 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 surrou nding 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 i s 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 wat er 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.

Eight-year-old Cieran Kelso and Winter the dolphin have more things in common than most people and dolphins. That is because they both have prosthetic limbs（假肢）！
Winter, the star of the movie Dolphin Tale, is Cieran‟s idol because they both swim with the help of prosthetic flippers. Florida‟s Clearwater Marine Aquarium, where Winter lives, usually only lets visitors swim in the dolphin tank every three weeks or so, b ut when its chief officer David Yates heard Cieran‟s story, he said he must make a swim-and-greet happen.
Local tourism officials flew Cieran and his family to the aquarium from England after a year of planning. His parents had a hard time keeping the surprise a secret for so long! They told Cieran that the trip was just going to be a business trip for his father Gary, and it wasn‟t until they were halfway there that flight attendants announced that the trip was actually for
