More children in China are putting on weight.In 2018，16 percent of Chinese children were overweight，according to the National Health Commission（NHC）.
Being too fat is bad for children' s health.According to the World Health Organization （WHO），overweight children are more likely to develop diseases like diabetes（糖尿病） at a younger age.This can lead to a higher chance of earlier death.
On Oct 23rd，the NHC，together with five other national departments，worked out a plan.The plan aims to reduce the growth of fatness among children aged 0﹣18 years by 70 percent from 2020 to 2030，Xinhua reported.
Kids are putting on weight because of changes in their diet and lifestyle，according to experts.Too much schoolwork and greater use of electronic devices（ 电子产品） could also be a cause.
According to the plan，teachers should not allow their classes to run too late or too early.They should make sure that students have breaks and enough physical（躯体上的） activity.School students should have at least three hours of active physical activity each week.
Parents should reduce their children's use of electronic devices and stop their children from eating foods that are high in sugar，fat and salt.

March 16 is International Sleep Day． Studies have shown that a good night's rest helps us stay healthy， both mentally（精神地） and physically（身体地）． Sleep is probably the best tool we have for memory and learning． A good night's sleep helps to learn better．
But what about getting rest during the middle of the day？ Short periods of sleep after a mid﹣day meal， we call it napping（午睡）， may help our brains work better．
Past studies have shown that napping can help babies and young children learn better． And napping can help brain performance in older adults． Taking a nap may also help this group of peoplefight off age﹣related memory loss． As we all know， the older we are， the more memory we will lose．
The study found that people who took an hour﹣long nap did much better on mental tests than those who did not nap． The hour﹣long nappers also did better on the tests than those who napped for shorter and longer periods． In this study， it seems that the most effective（有效地） nap lasted for about an hour， but not much longer． Keep in mind， however， that these are the findings for those over the age of 65．
And there is a little difference between the old and young people． Doctor Michael Twery notes that an hour long nap may be too long for young， healthy adults． And 30 minutes is enough to remove the pressure to sleep and will help them feel more awake（清醒的）． If they nap longer， they will get trapped into（受困于） deep sleep， which can be hard to get out of．
If you have trouble falling asleep at night， limit（限制） your daytime nap to under 45 minutes． Also nap before 3 p．m． in the afternoon．

Around the world，there are about 7，000 National Parks．Most of them cover huge areas of land where nobody lives．However，the National Parks in England include places where people live and work，as well as wild areas where there are few human activities．
The National Parks in England are called"England's Breathing Spaces"because they are places where people can go to be in the open air，away from the dirt and noise of cities．They provide wonderful scenes of mountains，woods，grasslands and wetlands．And there are plenty of activities to do in all of the National Parks in England．Visitors can walk or ride bikes for fun．Many of the parks put on activities for families．
Every year there are about 110 million visitors to the parks，bringing many benefits（益处） to the
areas．At the same time，it creates problems too．First，life can be difficult for local people．Car parks and roads are too crowded．Gift shops and cafes take the place of many everyday shops．Even house prices in some areas can become too high．Besides，country roads can be damaged，for too many people walk，cycle or ride horses on them．Roads can be rebuilt，but then they look less natural．Another big problem to the National Parks is litter．In the parks it is a danger to wild animals．Broken glass can also cause fires by focusing the rays of the sun．Such fires in wild places can be out of control．All National Parks in England are making more rules，which tell people how to take good care of their environment．If these rules are followed，the National Parks will be well kept and continue to give pleasure to
many people for a very long time．

More than 50,000,000 people live in the rainforests of the world and most of them do not hurt the forest they live in. They eat the fruits that grow on the forest trees, but they do not cut them down. They kill some animals to eat, but they do not destroy them.
When we cut down the rainforests, we destroy these forest people, too. In 1900, there were 1,000,000 forest people in the Amazon forest. In 1980, there were only 200,000.
The Yanomami live along the rivers of the rainforest in the north of Brazil. They have lived in the rainforest for about 10,000 years and they use more than 2,000 different plants for food and for medicine. But in 1988, someone found gold in their forest, and suddenly 45,000 people came to the forest and began looking for gold. They cut down the forest to make roads. They made more than a hundred airports. The Yanomami people lost land and food. Many died because new diseases came to the forest with the strangers.
The Yanomami people tried to save their forest, because it was their home. But the people who wanted gold were stronger.
Many forest people try to save their forests. Chico Mendes was famous in Brazil because he wanted to keep the forest for his people. “I want the Amazon forest to help all of us-forest people Brazil, and all the Earth,” he said. A few months later, in December 1988, people who wanted to cut down the forest killed Chico Mendes.
In Borneo, people were cutting down the forest of the Penan people to sell the wood. The Penan people tried to save their rainforest. They made blockades across the roads into the forest. In 1987, they closed fifteen roads for eight months. No one cut down any trees during that time.
In Panama, the Kuna people saved their forest. They made a forest park which tourists pay to visit.
The Gavioes people of Brazil use the forest, but they protect it as well. They find and sell the Brazil nuts(坚果) which grow on the forest trees.The number of the people living in the Amazon forest in 1980 was _______ of that in1900.
| A．half | B．one-third | C．two-fifths | D．one-fifth |
The people who _______ have destroyed the rainforest of the Yanomami.

Those people built roads and airports in order to ________.
| A．carry away the gold conveniently |
| B．make people there live a better life |
| C．stop spreading the new diseases |
| D．develop the tourism(旅游业) there |
We can infer the underlined word blockades probably means:

The coral reefs （珊瑚） of fine ecosystems that provide food and protection for many ocean creatures（生物）．The quarrel in almost all the oceans is in danger for pollution．Chemicals from factories end up in the seas and oceans and destroy（破坏） coral reefs．If the coral system die，some ocean creatures will be sure to die out．
Protecting the ocean also has something to do with the protection of ocean wildlife like dolphins．The fishing industry depends on modern ways to catch many fish in order to earn more money．But net for fishing also catch other sea animals．The fishing boat workers are advised to check their nets and set other ocean animals free．But the boats are in a hurry to make money and often other ocean animals are caught with fish．
Oil spills can destroy the ocean environment because of oil kills all ocean life．The world depends on oil and because there is plenty of oil off the shore in many countries．The need for you is more important than the risk of the oil spill．However，the fact is that one ocean mistake can lead to an ocean environment accident that will cause years of damage to the financial ecosystems．Or use bills will kill all the creatures in the area of the spill．The oil will be washed up on the shore and destroy ecosystems along the shore，including birds．

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？

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？

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．"
