Maybe you should sit down before you read this． It's a little frightening． Your sitting may be killing you．
Health experts say the U．S． adult now sits about 6.5 hours a day. That is up about an hour a day compared to 2007． The news is even worse for teens． They sit eight hours each day．The information was put out by the National Center for Health Statistics．It has collected the numbers for the past 16 years．It is worried about what it has found．
Research shows that people who are not active can get sick． Their bones get weaker． They burn fewer calories （卡路里）． That makes them more likely to put on too much weight． They might even get diabetes （糖尿病）． They are at risk for high blood pressure and heart problems， too．
Some experts also think sitting too much can influence how your blood moves through your body and how well your body fights off illness． Being active helps in lots of ways． It can make you happier， burn more calories and give you more energy． It can also help you sleep better．
About 60% of people in the U．S． watch at least two hours of TV each day． That number has stayed about the same in recent years．
Computers are the biggest reason for more hours spent sitting． Computer use outside of work or school has gone up for all age groups． Now， 50% of adults spend at least an hour of their free time on a computer each day． That is up from 29% in 2003．
About 53% of teens now spend at least an hour of free time on computers． So do 56% of kids． As many as 1 in 4 people who use computers use one for three hours or more outside of work and school．
So get up， take some breaks and go outside． You might save your life by doing outdoor
activities．

Sometimes we throw apple remains into forests，hoping small animals around may find them．But what if they are never noticed？People believe they would rot（腐烂）one day．So it doesn't matter．Is that true？
Sure they will．But it won't happen overnight．
Marjorie Woodruff，works in the Grand Canyon，set up a small experiment．She put a banana peel（皮），orange peels in a box，wide enough to allow small animals to go in and out．After six months，the orange peels had dried out，the banana had turned black．Nothing had been eaten or had rotted．
She buried the same things in sand and soil and six months later everything could still be seen．
In fact，it takes two months for apple remains to rot and an orange peel can take up to one year．
"Do we eat orange peels？ We do not．So why would a squirrel（松鼠）eat？ "Woodruff writes in High Country News． "The animals do just fine on nuts and berries．They do not need us．"There's another point to think about．
When animals start to get food from people．they may stop looking for their own food in nature．This is dangerous because it may weaken their hunting ability．Besides，they need different food．
Food waste also attracts animals to areas where there are a lot of people，says the Leave No Trace organization．This may put their life in danger as they may get used to looking for food alongside busy roads． Many of them are too small to be noticed by drivers．
When you're throwing fruit remains，you may be fined（罚款）．Fines are different．Some states might only fine people 100，but a few states fine people more than 6，000 for a first time．

（3）Which animal is mentioned？
（4）How much might you be fined at least if you throw fruit remains？
（5）Why can't we give food waste to animals？
How much sleep is enough？
To stay in good health，some expert in the US say，adults should get seven to eight hours of sleep．Teenager need nine to ten hours．And pre﹣school children need more than 10 hours of sleep a night．
Experts say the quality（质量）of our sleep becomes poor as we grow older．This happens because the brain unit that controls sleep begins to weaken slowly as we age．
Experts say the change starts in our 30s．By the time we reach our 50s，a person may have lost 50 percent of their ability to have a restful sleep.
These people have trouble failing and staying asleep through the night．From middle age on，these problems only get worse，and they can have a bad effect on their health．
Signs that show you may not be getting enough sleep．
You're always hungry or you've got unwanted weight．If you are in short of sleep，certain chemicals in your body will not work well and tell your brain in time that you have eaten enough．
You have trouble making decisions．Not having enough sleep may make your brain work slower in problem solving．
You have trouble remembering things．Sleep helps prepare the brain for new memories．
Your feeling changes unreasonably．People who don't sleep well may feel unable to control their feelings．
You are having trouble seeing．If there is a shortage of sleep，you may not be able to see thing as clearly as usual．
How to improve your sleep？Here are a few things people can do to get better sleep．
Health experts say that exercise and avoiding work on computers make people go to sleep more easily．A cool room is also a good choice for sleeping well．

We all waste food，you and me，every day，millions of tons of it．In China，enough food is wasted in restaurants every year to feed 200 million people．And the amount of food wasted by Chinese consumers is increasing fast．So our nation is being encouraged to stop wasting food．
So what should Chinese consumers do to prevent food waste？
♦Keep a kitchen diary
All of us should keep a kitchen diary，and we can know that how much food we waste at home．The first thing for us to do is to stop throwing away food that we can still eat．We should eat everything we buy and if we cannot，we should buy less．
♦Buy only what we need
We should ask for smaller portions in stores．We should also check how much food we have before buying more．We shouldn't bring much food we don't need home even if large posters ask us to do so．
♦Develop the habit of packing food．Chinese consumers are generous and friendly．In restaurants，often too much food is ordered and served．So when ordering out，we are supposed to exclude the food in the order if we don't plan to eat it．And order smaller servings in restaurants and take home what we cannot finish．
Don't put it off! Let's stop food waste today!
（1）Why is our nation being encouraged to stop wasting food？
A．Because there's enough food for Chinese people．
B．Because Chinese consumers like to try delicious food．

There are many ways to help improve your health like eating healthy food． taking exercise and getting medical help． But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night． The general sleeping rule is that the younger you are． The longer sleep you need． But regardless of（不管）age， some people need to sleep more while for some a few hours is enough．
The problem with sleep is that more and more people in the world are not sleeping enough．According to the World Health Organization over half the people in the world may be sleep﹣deprived． Having less sleep not only makes people feel tired but also causes accidents． In the United States alone， sleepy drivers cause at least 100，000 traffic accidents a year． Also sleep problems can cause medical problems such as high blood pressure（血压）．
Why are so many people sleep﹣deprived？ Part of the reasons may be cultural． In the American culture， people put a higher value on work than on sleep． In fact， peopele who sleep a lot are usually seen as "lazy"． Also， you can sometimes hear some people say proudly that they don't have much time to sleep． they only sleep four or five hours a night． It seems that the less you sleep， the more work you'll do．
How do we teach these people to learn the value of sleep？ Perhaps they may listen to the advice of Dr． James Maas． an expert（专家） in sleep． He says ，"Sleep is like a credit （信用卡） card． When you sleep less． you are only borrowing time． You always have to pay it back． The more hours you don't sleep， the more hours you should't sleep to "pay back" the hours on your 'sleep credit card．'"
For those who value work more than sleep， they should listen to what a famous person once said． "Don't think you will be doing less work because you sleep during the night． That is a foolish（愚蠢的） idea which is held by people who have no imagination． You will be able to do more．"

In the 13th century． Marco Polo the world known Italian travelled， saw many wonderful things in China． One of the things he discovered was money made of paper． People in the West did not have such kind of money until the I5th century． However ，the Chinese began to use it in the 7th century．
Paper was invented by a Chinese man called Cai Lun almost 2，000years ago． But it was not made in Europe until the year 1100． Four hundred years later， a German discovered that he could make the best paper from trees． After that countries rich in forests， such as Canada ，Sweden， America， Finland became the most important ones in paper making．
Paper can be used in many ways． The common uses include newspapers magazines and books． But do you know that paper can be used for keeping warm？ In Finland． the farmers wear paper boots to keep their feet warm in the snow． And even houses can be insulated（使绝缘）from heat or cold with paper．
However． we have to understand that paper still comes from trees now． If we keep on wasting so much paper， there will not be any trees left on the earth some day in the near future． Every day people throw away about 2， 800tons of paper in our city． It takes 17trees to make one ton of paper． This means that we are cutting down nearly 48.000trees every day． The fact is that it takes more than 10years for a tree to grow．
So we must start saving paper right now． We can use both sides of every piece of paper． We can make useful things out of used paper． We can use china cups instead of paper ones． When shopping， we can use fewer paper bags and reuse them if we have some
In short， we should keep a balance （平衡）between using paper and protecting trees， and do it now before it is too late．

What do you do with your rubbish？Throw it out？You don't know what you're missing!Look closely at the two figures on your left.They were made from things most people throw away.The figures were made from used bottle caps.Those two bottle﹣cap figures were exhibited （展示） in a museum.
Folk art is art made by common people who have not been trained as artists.Their work is often based on traditions in their culture.Fine art，on the other hand，is usually made by people who have had training in art.Works of fine art are valued for their artistic beauty.They are supposed to be looked at but not used.Works of folk art，however，are often made for everyday use.
There were more than 800 pieces of folk art from nearly 50 countries in the exhibition.All of the pieces were made from used metal，wood，cloth，and plastic.The artists come from many different cultures.Still，they all share one thing.They take objects that are normally thrown away and change them into objects that are beautiful，useful，and fun.The artists may not think of what they do as recycling，but that's exactly what it is.Fine artists might work with expensive materials.They might use expensive tools to shape these materials into works of art.On the other hand，in poor countries rubbish might be the only material folk artists and toy makers can afford.The exhibition shows that a rich imagination is very important when there are only poor materials.Recycled art began long before people began to think about recycling.Some of the objects in the exhibition date from the 1930s.
Even if you don't create art out of rubbish，it's good to save our natural resources.Remember the three rules：reduce，reuse，recycle.If you reduce waste，true things instead of throwing them out，and recycle materials such as paper，plastic，and glass，you will protect the environment.

Each weekday， more than 30 million students in Canada eat meals in school cafeterias． And when lunch is over， they fill the rubbish cans with uneaten food．
More than ＄1 billion worth of food is wasted every year． Wasted food is wasted money．It's also a missed chance to feed hungry people．And it's had for the environment：farming， packing， and transporting food produces greenhouse﹣gas emissions（温室气体排放）． They pollute the air．
Schools have developed ways to cut back on（减少） waste． Making lunch period longer helps． It gives kids time to eat everything on their plates． Many schools follow government rules that say students must take a certain number of healthy things at mealtime． Those rules help kids get a better meal． But they can lead to more waste． That's why schools in Canada set up something called share tables．Students put untouched food on the table． A student who wants the food can take it． There are rules to make sure the food is safe． Food that isn't taken from the table is served another day．
Students also waste food because they don't like how it tastes． Cook Sam wants to change that． He works with a program called Cooks in Schools． He helps dining hall workers develop dishes kids enjoy．
You can fight food waste too． At the store， look for "ugly" produce．Fruits and vegetables with bad shapes are still delicious， but they are often not noticed． At home， read safety labels（标签）． If a label says "best before"， the food is still safe to eat for a little while after the date． If the label says "use by"， the food is no longer safe after the date．
（1）What does the underlined word "cafeterias" mean？
A． Dining halls
B． Classrooms
C． Hallways
（2）What is NOT the result of wasting food？
A． Wasting money
B． Bad for the environment

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.
（1）Is it an easy job for Wang Chengbang to plant trees？
（2）How many trees has Wang Chengbang planted so far？
（3）What is Wang Chengbang successful in？
（4）In the summer holiday，do you want to be a volunteer to work with Wang Chengbang？Why or why not？
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 |
4 |
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.
（1）What's the latest tool a dog might have in the fight against cancer？
A.Tooth.
B.Nose.
C.Ear.
（2）What happened first in the Pine Street Foundation test？
A.The dogs were trained.
B.The tubes were placed one yard apart.
C.The dogs smelled the tubes.
（3）What was a dog supposed to do when it smelled cancer？
A.Smell again.
B.Turn around.
C.Sit down.
（4）Look at the chart.How many times did the dogs keep standing when they smelled the breath from healthy persons？
A.Less than 10 times.
B.Almost 600 times.
C.About 700 times.
（5）Why do many experts question the dog's smelling power？
A.Because no lab test for cancer has given more correct results.
B.Because the dog trainers influenced how the dogs acted.
C.Because they don't think this study is important.
Eight years ago， 1﹣week﹣old Diandian was left behind． When people found her in the reeds （芦苇） of a lake， she looked too weak to survive． Now she is the mother of three milu， thanks to the workers' attention and care at the East Dongting Lake National Nature Reserve．
Li is the president of a milu conservation association in Yueyang and head of a local milu and bird rescue center， where 11 deer， including Diandian， have their families． Li and his workmates need to work extra hours to take care of the animals from March until mid﹣May． He remembers March 18 this year． He fed Diandian some fresh shoots and leaves for breakfast as usual， and moments later when he returned，a newborn milu was right beside her． Since it is her third baby and born in the third month of the year，people named it Sansan， referring to "three﹣three"． Li has developed a deep affection for milu and made up his mind to protect them． "As our country is paying more attention to environmental and wildlife protection， people are increasingly aware that milu are state﹣protected animalsm，" Li said．
Milu habitats （栖息地） are usually centered around water， and fishing equipment that used to be a threat to the animals is no longer seen in nature reserves． On May 27， a team of experts went to watch milu near Dongting Lake． It takes time and luck to meet one and count them especially when they live in the thick reeds that are 4 to 5 meters tall． The team leader Song， saw a milu for the first time when he was studying for his doctorate in zoology early in 2009． Since then， he has helped protect the habitats at Dongting Lake． As the flood season is coming， Song and his workmates will go around the lake area day and night to save deer in trouble， and provide feed for the animals when needed．
As the environment improves in and around Dongting Lake， China's second﹣largest freshwater lake， the wetland has become cover once again for wildlife． "We will continue to protect these rare animals and their living environment，" Song said．

You don' t have to be a scientist to solve big environmental problems． One Dutch designer is finding creative ways to make a change﹣and he's inviting bikers to join him．
Daan Roosgaarde， 38， is a designer from Holland． He uses creative ideas to improve city life． For his Smog （雾霾） Free Project， he designed a special tower that cleans air in Chinese parks． In Holland， he designed a shining bicycle path．
Now Daan and his team are working with engineers at Chinese bike﹣sharing company Ofo to create a new product for public use． It's an air﹣cleaning machine connected to a bicycle and is part of the Smog Free Project． In smoggy weather， the machine would breathe in the air in front of the bike and blow out a stream of clean air toward the biker's face．
It's no secret that air pollution is a big problem for China． In winter， it's common for thick clouds of haze （霾）， caused largely by factory production， burning of coal and car emissions （排放物）， to cover areas of China．
In 2016， only one﹣fourth of Chinese cities met the country's air quality standards， according to a survey of 338 cities nationwide from the Ministry of Environmental Protection．
"Of course one tower and a few bikes won't solve China's air pollution problem，" Daan said， "But smog﹣free bikes are an exciting idea that will hopefully inspire communities to create greener cities．"
