Over time, animals have developed many ways to stay away from predators(食肉动物)．Hiding is one of the best ways to stay alive．
Master of disguise(伪装)
Some animals hide by looking like the places where they live．Let's look at the leafy sea dragon．It is a master of disguise．
The sea dragon is covered with skin that looks like leaves．The skin helps the dragon look like a piece of seaweed．A hungry meat-eater would stay away from anything that looks like seaweed．
Skin is just one part of the sea dragon's disguise．Its fins(鳍)make another part．They are small．They slowly push the dragon through the water．So the dragon looks like it's floating－just like seaweed．
Show the colors
The leafy sea dragon hides to stay safe．Other animals stay safe by showing their colors．They want other animals to see them．Scientists call these bright colors warning colors．The colors tell predators to stay away．Think, for instance, what happens when a yellow bug flies in your face? Yellow is a warning colour．It tells you that it might be a bumblebee(大黄峰)．You don't want to disturb those insects．
Blending in
Many animals use colors to match the place they live in．Some even change colors with the seasons．
The snowshoe hare has brown fur in summer．It blends in with the colors of fields．In fall, the hare loses its brown fur．It grows thick white fur．The new fur matches the snow in winter．
On the ball
The armadillo(犰狳)is only about two feet long and weighs 15 pounds．It has small teeth．So it cannot even bite to protect itself．
When an armadillo recognizes a predator, it first tries to run away．A scared armadillo rushes for the safety of its underground home．If an armadillo cannot get away, it hides in its shell (the armadillo has an armored shell)．Most hungry hunters cannot bite to eat a living ball．

“Our aim is to take our art to the world and make people undertand what it is to move．”said David Belle, the founder of parkour(跑酷)．
Do you love running? It is a good exercise, yet many people find it boring．But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks ove ________ obstacles on the way．It is just because of Bond's wonderful performances that the sport has become popular worldwide．
Yes, that's parkour, an extreme street sport aimed at moving from one point to anoth-er as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body．Parkour is considered an extreme sport．As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop．
Parkour can be just as exciting and charming as it sounds, but its participants see park-our much more than that．
Overcoming all the obstacles on the course and in life is part of the philosophy(理念)behind parkour．This is the same as life．You must detemine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life, to reach the destination successfully．A parkour lover said,“I love parkour because its philosophy has become my life, my way to do everything．”
Another hilosophy we've learnt from parkour is freedom．It can done by anyone, at any time, anywhere in the world．It is a kind of expression of trust in yourself that you earn energy and confidence．
