Air pollution is a big problem for cities in most countries． Many people are dying from it． But how can we tell the air quality is good or bad？
On a tree next to a river in Amsterdam， a tiny birdhouse glows （发光） bright green when the air is clean． If you're standing nearby， the birdhouse will also give you a free Wi﹣Fi connection﹣but only if pollution level is low enough． The designer is Joris Lam． His birdhouse tells you about the air quality．
Joris' birdhouse is called TreeWifi． It can be put on a tree around your house to test the air quality． People can see a screen with information about the local air quality and how to improve it． TreeWifi is a simple way for people to know about the air pollution around them． If the birdhouse does not glow， people should care more about the environment． It reminds them to change their lifestyles． For example， to protect the air， they can ride bikes or just walk instead of driving cars．
"Imagine if trees gave free Wi﹣Fi， people would plant more trees like crazy． It's a pity that they only give us the oxygen（氧气） we breathe，" Joris said．
The birdhouse doesn't work as a home for birds now． Joris and his team are trying to make some changes to it． In the future， they hope birds will live in the birdhouse and the heat of its green light will be used to keep birds warm in winter．

Do you often run outdoors to keep healthy？ Have you ever thought about how running helps to clean up the earth？ Sometimes a creative mind can bring us a win﹣win（双赢） situation．
Plogging，a new way to exercise， began in Sweden（瑞典）． The name "plogging"" comes from two words﹣the Swedish（瑞典的） word "plocka"， which means "to pick up（捡起）"，and the word "jogging"，which means "to run slowly"．A Swedish man called Erik started the movement．He saw rubbish here and there when riding to work each day．He became worried about the dirty environment and decided not to go to work by bike any more．Instead， he began to run to work and pick up the rubbish at the same time．To his joy， more and more people followed him and soon plogging became popular．
Many people choose plogging instead of just jogging because they think plogging is a good way to help clean up the earth．Sometimes rubbish is difficult to collect because it may scatterall around． But if the runners pick up the rubbish on the way， it is quite different． After all， many hands make light work． Another reason is that plogging burns more calories （卡路里）． According to a research， plogging for 10 minutes burns 48 calories， while usual jogging for 10 minutes burns about 39 calories．
Everyone on the earth should play a part in cleaning it up! It's time for us to take action together．So ready？ Let's plog tomorrow!

In today's world， almost everyone knows that air pollution and water pollution are harmful to people's health． However， not all the people know that noise is also a kind of pollution， and that is harmful to human health， too．
People who work and live under noisy conditions usually become deaf． Today， scientists believe that 10% of the workers in Britain are becoming deaf because of the noise where they work． Many of the workers who print newspapers and who weave cloth（织布）become deaf． Plenty of people living near airports also become deaf． Recently it was discovered that many teenagers in America could hear no better than 65﹣year﹣old persons， because these young people like to listen to pop music and most of pop music is a kind of noise． Besides， noise which is produced by jet planes or machines will make people's life difficult and unpleasant． It can make people ill or even drive them mad．
It is said that a continuous noise of more than 85 decibels（分贝）can cause deafness． Now the governments in many countries have made laws to control noise and make it less than 85 decibels．
In China， the government is trying to solve not only air and water pollution problems but also noise pollution problems．

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.
Now，at the age of 85，Wang Chengbang is still working.

（2）How many trees has Wang Chengbang planted so far？

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. |

| Breath Sample |
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 |

720 |
No lab test for cancer has given more correct results than this test.The results are so amazing that many experts question the dogs' smelling power.They wonder if there were other reasons why the dogs did so well.For example，they thought the way the dog trainers behaved could have influenced how the dogs acted.However，most experts agree that this study is important.The information could help scientists create a simple breath test for cancer in the future.Once again humans may be getting a helping paw or nose﹣from their best animal friends.
