Thanks to better health care， most people are living healthier and longer lives． Someone who is born today can expect to live about thirty﹣five years longer than someone who was born in the nineteenth century． It is even thought that in the future more and more people will celebrate their hundredth birthdays． Here are some rules for a health life．
Get off the sofa!
Sure， it is comfortable to sit on the sofa and watch TV． But doctors say you should get off the sofa． To keep fit， you have to walk at least 10000steps every day． In the past， people's jobs required more physical effort． They often had to walk for miles every day． When farmers were working in the fields， they were keeping fit at the same time． Think about it： Do you get the same amount of exercise today as they did in the past？
Eat healthy food!
It is important to eat food that is fresh and natural， for example， fruit and vegetables． Fast food is not healthy． You should only have itonce in a while． Eating too much of the wrong food will harm your health．
Rest while you can!
When we were babies， we slept for much of the night． Teenagers do not need as much sleep as babies， but it is important for you to get about eight hours' sleep a night． At weekends， you have got more time， so use it not just for your friends， but for rest too．
Do not worry， be happy!
Many people believe that happiness is important for our general health． Sometimes it is not easy to be a teenager because of the difficulties of school， exams or friendships． If you are worried about something， talk to your parents or your teacher．

Governments around the world are pushing for an end to plastic straws （吸管） and bags.More and more businesses are turning to paper products as a choice.Paper is considered by many to be better than plastic.However，it，too，is harmful to the environment.
Firstly，paper bags and straws are made from trees.Trees，as you know，can reduce （减少） carbon dioxide （二氧化碳） levels in the atmosphere. Theycan slow down climate （气候） change.An increase in the use of paper bags can cause more acts of cutting down trees.
Secondly，products made from paper require more energy and water.About 10 percent more energy and four times as much water is used to produce a paper bag than a plastic one.You might say that we can use recycled paper to save that energy and water.This seems to be a good idea.However，it takes even more energy and water to go through the recycling process than to make a brand new paper bag.Products made from recycled paper are also often short﹣lived.
Thirdly，paper products are heavier than plastic ones.That means they require more oil to transport.Seven trucks are needed to transport two million paper bags，while only one truck is needed to transport the same number of plastic bags.The increased weight also leads to a large amount of waste once the bags are thrown away.
Paper products are actually a lose﹣lose for both the environment and businesses.They are more expensive than plastic products.A paper straw costs about 5 to 12 cents，while a plastic one usually costs only about 2 cents.
The most environment﹣friendly solution is to avoid single﹣use products altogether.Products like glass water bottles and steel straws can be used over and over again.They are much better than either paper products or plastic products.Through increasing the use of these products，you can greatly reduce your throwaway waste and truly make our Earth a greener place!

There are several causes leading to poor eyesight like not enough food，genes （基因） and aging （老化）．Televisions，computers and reading are also the causes of having poor eyesight．If you happen to work in front of the computer，it is best to take a break every once in a while．Something dirty can cause redness and they will make you feel uncomfortable．It is bad for your eyes，too．If this happens，the best way is to clean your eyes by using cold water．You must also try your best to protect your eyes from harmful things．For example，sunglasses are not just for fashion but they can also serve as a great way to protect your eyesight form UV rays．

Paying for bus rides with plastic usually makes people think of plastic bus cards．But one Indonesian city has decided to accept plastic recyclable waste in place of money for city buses．
Surabaya， Indonesia's second largest city， located on the eastern end of the country′s main island Java， made this decision in April 2018．Now，locals can pay for their bus rides by putting plastic cups or bottles directly on the bus．A two﹣hour bus ride costs 10 plastic cups or 5 bottles．
Indonesia is the second largest ocean plastic polluter， producing up to 2.4 million tons of plastic waste into the oceans every year according to a report．Only in Surabaya nearly 400 tons of plastic waste is produced every day．The head of Surabaya's transportation department（交通部门） said，"With this decision， we hope to raise public awareness about environment， especially people's awareness about plastic waste．"
Each city bus can collect up to 550 pounds of plastic bottles and cups every day．The collected bottles are sold to recycling companies and the money earned from it goes toward running the bus companies and providing money for green spaces in the city．This is certainly turning rubbish into a national treasure．
The decision is part of the city's purpose to become plastic waste﹣free by 2020．In order to encourage local people to take buses，the city also added the new Suroboyo buses．The new buses are air﹣conditioned，comfortable and easy for elderly and disabled passengers to get on and off．
The program is well received．People in Surabaya said，"We can reduce waste so it doesn't pile up at home because we can just bring it in and make good use of it． It is a win﹣win situation．"
This type of program can be a model for other cities worldwide and encourage citizens to recycle their plastic waste．
回答下面5个问题，每题答案不超过六个词．
（1）Instead of money， how can locals in Surabaya pay for bus rides now？
（2）How much plastic waste does a two﹣hour bus ride cost？
（3）How much plastic waste is produced in Surabaya every day？
（4）What is the purpose of the new program？
（5）What do local people think of the new program？
A new report from a university says 80% of the world's teens don't get enough exercise every day， The report was based on （基于） a research done with about 2 million students aged 11 to 17 around the world．According to the report ， activity standards are different in different countries and they are also different between boys and girls． In China， for example， only 20% of the boys are active enough， compared to 11% of the girls．
Why don't teens go out for exercise？ One main reason is that they always have technology products in their hands or around them． They spend too much time on smartphones，computers and TVs in their free time． Many teens find it very hard to pull themselves away from these devices （设备）．The report says that young people need to do less in the digital world but more in the real world． It advises kids to get at least an hour of exercise every day． This could include running， biking， playing sports， or many other outdoor activities．
More and more research shows that exercise not only helps the body， but also helps the brain．Besides， doing sports helps kids to make friends． Mark， a sports fan， started to play football when he was six years old． He used to be shy and weak， but now he has become taller and stronger．He gets to know the importance of communicating with his teammates and how to learn from mistakes and failure．And he has made lots of friends with the same interest． They often have football training on the playground． They have more to talk about and enjoy the happiness after training．
根据短文内容，回答下列问题．
（1）How many students around the world took part in the research？
（2）Are activity standards the same between boys and girls according to the report？
（3）What does the report advise kids to do？
（4）When did Mark start to play football？
（5）Where do Mark and his teammates often have football training？
In our daily life， much plastic package is used just once and then thrown away． According to a new study from the University of California， 9% of this is recycled， 12% is burnt and 79% goes to landfill． And because most plastic doesn't biodegrade， once it's in the ground， it stays there． （1）The study also shows that eight million tons of plastic waste are pouring into the sea every year．
Scientists have calculated the total amount of plastic ever made： 8.3 billion tons． That's as heavy as one billion elephants． And almost all of it has been made in the last 65 years．
（2）每个人都应该参与拯救地球． Protecting the environment is protecting ourselves． If the environment is taken good care of， we can have clean water and green mountains． （3）绿水青山或是金山银山．
What can we do as students？ Just say no to single﹣use plastics like straws， cups and bags． Many people love to drink from a straw or use plastic to carry things， but they are really bad for the environment．
（4）Bring your own chopsticks if you're planning to eat outside． It can be hard to remember．
Just put a pair of chopsticks in your bag before you leave home．
You know you're going to need some water to get you through your day． So carry a bottle（or a cup） with you． （5）That will help you avoid plastic bottles．

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 |

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.

Wash your hands． You need to wash your hands with soap and water before you eat， after you use the toilet， and after you touch animals， because your hands may carry viruses （病毒）．Cover your nose and mouth． When someone sneezes（打喷嚏）or coughs，the viruses can travel as far as one meter through the air，so you'd better stand a proper distance while talking to someone who has a cold． And always cover your mouth and nose with a piece of paper when you sneeze or cough，and then clean your hands． Wear a mask（口罩）． Some doctors say that masks can stop the virus as much as 80%， but if you don't wash your hands often， it's no use wearing a mask． So it's necessary to wear the mask in the groups of people．
Do sports often． Exercises will help make your body strong enough to resist（抵抗）the virus．
