Trees are one of the oldest" citizens（公民）" of our Earth． They keep our air clean ， reduce noise pollution， improve water quality and provide food and building materials．
Just like us， trees change a lot as they grow． At I to 3 years old， young trees learn how to protect themselves． For example， many trees grow thorns（刺）to warn animals not to go near． Most young tree have large， deep green leaves so that they can catch enough sunlight and change it into their food and energy．
When trees are 4 years old， they begin to grow very rapidly and become strong enough to face challenges later in life． At the age of 15， trees become young adults． They grow more slowly and begin to produce flowers and fruit．
It is not until the tree is 20 to 25 years old that it becomes a real adult． The tree reaches its largest size． The adult tree gives us shade， oxygen and natural beauty； it is also a great place for a tree house， or a place for us to read a book， listen to music and so on． If we give the adult tree proper care， it will go on to live healthily for many years．
Gradually， trees begin to grow older and older and even die． At this time， they still have their important place in nature． When a tree becomes hollow（空心的）or part of it becomes dead， it provides a home to small animals and is a source of food for many other animals．
In many ways， the life of a tree is similar to our own life experience． When we are looking at the life of a tree， we learn about that each period of life brings its own form of joy and challenge．
Enjoy every minute of the life of the trees and take care the trees!

In 1988，Wang Chengbang retired（退休）from the army.Instead of enjoying a relaxing life，he volunteered to save the soil from desertification（沙漠化）by planting trees in Korla，Xinjiang.
It is no easy job.The high temperature in Korla makes it difficult for anyone to work day after day in the sunshine.Besides，water is a big problem.In fact，Wang Chengbang's work in the first few years failed as very few trees survived（存活）.
But Wang Chengbang would not give up."After trying many different ways，I have learned how to grow young trees in a better way，" said Wang Chengbang.He also worked out new ways to save water.With his hard work，more and more trees have survived.So far，he has planted more than 1.5 million trees.Those green trees prevent desertification，make the air cleaner and protect people from the hot sun.Now，Korla is a model city in environmental protection.
Wang Chengbang is also successful in fighting cancer（癌症）.In 2005，he had cancer and was told that he had only six months to live.However，he continued taking care of his trees rather than lying on the hospital bed."Working is the best medicine.Planting trees helps to fight cancer，" he often jokes.

Do video games do harm to our children？Today，many children spend a lot of their free time playing games on the Internet.In the UK，99%of kids aged8 to 15 play video games every week.This information tells us that the benefits and dangers of video games must be carefully considered.
For many people，video games are fun.They have bright lights，funny cartoons and exciting stories.Everywhere you look，you can see children playing these games.They play on buses and trains，in restaurants and even at school.
Video games are educational too.They make kids think in a creative way and theyhave to move their hands and eyes quickly.This can improve the way that a child's brain works.What's more，video games make children use their imagination.The player has to do many creative things，like drawing，telling stories and building things.Video games are also a good way to teach children about technology because they can learn how computers and other devices work while they play.
However，a recent study suggests that video games can also be bad for children.First，children can download many games for free.This means that parents often don't know if their children are playing violent or scary games.Second，many children spend too much time playing games on computers and this can lead to health problems.Third，if children spend too much time playing games instead of doing homework，they can have problems at school and get bad grades.Finally，video games can affect children's social skills.If children spend too much time playing video games by themselves，they might not learn how to play with their friends.
In conclusion，it seems clear that video games have some advantages and some disadvantages.It is up to parents to know what games their children are playing and how much time they spend on them.Parents should also make sure their children get enough exercise and spend time with other children.

Dogs might have the latest tools in the fight against cancer （癌症）：their noses!Researchers at California's Pine Street Foundation （PSF） say they have trained five dogs to smell cancer on a prison's breath.This could be exciting news.
A dog's sense of smell may be 10，000 to 100，000 times stronger than ours.But can dogs really smell illness？PSF researcher Michael McCulloch says yes. "We were very surprised by how exact they were，" he said. "They were telling who had cancer，and they were also saying who didn't."
McCulloch and his team asked four healthy people and one with cancer to blow into plastic tubes （塑料管）.Special materials in the tubes kept the things of each breath.The tubes were then placed one yard apart.Finally the dogs were allowed to smell the tubes.Each dog had been trained for three weeks to sit when it smelled cancer.Ninety﹣nine percent of the time，the dog sat next to the tubes blown into by patients with lung cancer.The dogs were right 88 percent of the time about breast cancer.
| Dogs in the Pine Street Foundation test were trained to sit when they smelled cancer.How well did they perform？Take a look at this chart to find out. |

Number of Times the Dogs Sat Down |
Number of Times the Dogs Kept Standing |
| Breath from lung cancer patients |
564 |
10 |
| Breath from healthy persons |
