    As we all know，trees are always stationary：they stay more or less where you plant them，and no one worries about finding a tree wandering around a park or back yard.
    However，there is one special exception，some say：the so called walking palm tree（棕櫚樹(shù)） was found in the rainforests of Central and South America.Many people believe it can really walk around.This is because of its unusual root system：while most trees have one trunk，the palm breaks into many smaller roots a few feet off the ground，giving it the appearance of many little legs.
    The amazing walking ability of the palm tree has always been told by rainforest guides to tourists for years，and appears in many sources of documents as an amazing plant adaptation.As journalist Sherry Seethaler writes in her book Curious Folks Ask 2： "Screen writers searching for the perfect B-movie（小成本電影） plant hero could take inspiration from the walking palm.The tree slowly walks from shade to sunlight by growing new roots toward the light."
    A tree that walks in search of the sun is a fascinating，strange story.And it's not true either；the tree is real enough，but it doesn't walk.It sits where it began to grow，not moving except under the force of wind or an axe.
    Biologist Gerardo Avalos is one of the world's top experts on the palm tree.His analysis of the plant and its roots shows that the walking tree can't walk because its roots don't move.A few roots on one side or another may die off，but the trunk itself remains，well，rooted to the spot.
    "My paper proves that the belief of the walking palm is just a myth，" Avalos said. "Thinking that a palm tree could actually track the sunlight changes by moving slowly over the forest floor...is a myth that tourist guides find amusing to tell visitors to the rainforest."

1．Animals are natural resources that people have wasted all through our history.
   Animals have been killed for their fur and feathers，for food，for sport，and simply because they were in the way.Thousands of kinds of animals have disappeared from the earth forever.Hundreds more are on the danger list today.About 170 kinds in the United States alone are considered in danger.
   Why should people care？Because we need animals.And because once they are gone，there will never be any more.
   Animals are more than beautiful or interesting or a source of food.Every animal has its place in the balance of nature.Destroying one kind of animal can create many problems.
   For example，when farmers killed large numbers of hawks（鷹），the farmers' stores of corn and grain were destroyed by mice.Why？Because hawks eat mice．With no hawks to keep down their numbers，the mice multiplied quickly.
   Luckily，some people are working to help save the animals.Some groups raise money to let people know about the problem.And they try to get the governments to pass laws protecting animals in danger.
   Quite a few countries have passed laws.These laws forbid the killing of any animal or plant on the danger list.Slowly，the number of some animals in danger is growing.

2．If you are a teenager without a job，you probably do not have much extra money.Sometimes parents will give their children a weekly pocket money for doing small housework，but it is often not enough once the children grow into teenagers and want to do things with their friends all of the time.How to make money is an important thing for teens to learn.If you're wondering how a teenager can make good money，some ideas might be：
