COVID﹣19（新冠肺炎）is spreading all over the world． What should we do to prevent the virus（病毒）from spreading？ Here are the suggestions．
First， we should seldom go out． It's easier to get sick outside． When we have to go out， we must wear face masks（口罩）． Second， we should often open the windows in order to keep the air in the room fresh． Fresh air is good for us to keep healthy． Third， we ought to wash our hands many times a day， especially before meals and after going to the toilet．And each time we should wash them with soap and running water for at least 20 seconds． Fourth， make sure we have a good sleep at night． People who are tired or under stress can get sick easily， so it's important to have enough sleep． Lastly， we can do sports like walking or running slowly at home．
Everything will go well as long as we take good care of ourselves． We believe that we will win the fight soon．
（1）What must we wear when we go out？
（2）What should we often do to keep the air in the room fresh？
（3）How long should we wash hands each time？

Many environmental groups are warning that oceans of the world are in great danger． In the past 50 years，the number of water with zero oxygen（氧气） in the open ocean has increased more than four times． In the near coast water bodies， including the river mouth and seas， low﹣oxygen areas have increased more than 10 times since 1950．Scientists discover that oxygen continues dropping ever outside these zones as the Earth warms． To stop the drop，the world needs to control in both climate change and nutrient（养分） pollution．
Oxygen is a must to life in the oceans． The drop in ocean oxygen is among the most serious effects of human activities on the Earth's environment．
This is the first time for the scientists to take such a deep look at the causes， results and solutions to low oxygen worldwide， in both the open ocean and the near coast waters．About half of the oxygen on Earth comes from the ocean． However， mixed effects of nutrient loading and climate change are greatly increasing the number and size of "dead zones" in the open ocean and the near coast waters， where oxygen is too low to support most sea life．
In the areas traditionally called"dead zones"． like those in Chesapeake Bay and the Gulf of Mexico， oxygen drops to levels so low that many animals have trouble in breathing and die．As fishes run away from these zones， their living areas become smaller and smaller． But the problem goes far beyond "dead zones"． Even smaller oxygen drops can hold up the growth in animals and lead to disease or even death． Low oxygen also can cause the release of dangerous chemicals．Although a few animals can grow well in dead zones， overall biodiversity（多样性）falls．

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!

When you think of the Arctic （北极）， you imagine an icy land of pure white snow． Others imagine it as the last really clean place left on earth． We have polluted the deepest oceans with plastic rubbish． "And now"， CNN says， "It's the Arctic's turn．"
German scientists have recently found microplastics in Arctic snow． Microplastics are pieces of plastic smaller than 5 millimeters． Sadly， the scientists found 1800 pieces of microplastics per liter of （每升） snow．
How is plastic pollution reaching the Arctic？ According to scientists， "It's clear that most of the microplastics in the snow come from the air．" They fall off the plastic objects and are moved by the wind， just like dust． They mix with ice in the air and fall to the ground as snow． Finding these plastics in Arctic snow means that we may breathe them in．
Are they bad for us？ Scientists cannot answer this question for now， according to the WHO． We do know that our bodies cannot take in "large" pieces of microplastics． However， if the plastics are small enough， they can find ways into our bodies and stay there for a long time， which can be bad for our health． What's more， earlier studies have shown that microplastics may contribute to lung cancer risk．
Microplastics have also been found in rivers and oceans around the world． Earlier research has found that they flow over long distances and into our oceans， hurting ecosystems along the way． They start in our wastewater， then flow into rivers and out to the sea， where they are eaten by sea animals． If people then eat these animals， it means that we're eating the plastic as well．

Energy is everywhere in the world．We use energy every day．There are all kinds of energies in the world，such as hydropower resources，sun's energy，wind power．
Liangshan is called"kingdom of hydropower resources"．Jinsha River，Yalong River and Dadu River are just like three great dragons carrying hydropower resources to Liangshan from the
Qinghai﹣Tibet Plateau．The government has planned to build 11large and super hydropower stations on Jinsha River，Yalong River and Dadu River within Liangshan．On the other hand，there is rich wind power in Liangshan．The government is building a large wind power station between Huili and Ningnan．
Electricity is a form of energy，and this is what powers the TV，mobile phone，fridge and more．Our growing need for energy is one of the problems in the world today，because producing electricity also produces pollution．Although energy in Liangshan is very rich，we must do something to protect the environment and save lots of energy．
Here are some simple ways to make a big difference when we're using electricity．
On or off？Leaving TV and computers on with the little red light showing still uses electricity，even though they might look like they're turned of．To stop this，you can turn them off．
Light out!Turning light off when you're not in the room can save a lot of energy．
Fridge door closed．Try not to leave the fridge door open or put hot things inside when you used the fridge．Because it takes a lot of energy to keep cool．
Use the sun's energy．An increasing number of people are fitting solar panel to their houses．They create electricity from sunlight．which can then be used to make hot water or do the cooking and so on．

A zero﹣waste life is a lifestyle that hardly creates any rubbish． So， a zero﹣waste store is about providing a kind of everyday and pleasant﹣looking zero﹣waste products to help people start on a zero﹣waste life journey．
"Zero waste" or "danshari" was first suggested by a French woman called Bea Johnson． Her idea is： live a life and try not to create any rubbish； use different kinds of ways to save the environment such as stopping the use of one﹣off objects； giving unwanted things to others or giving them away to organizations like the Red Cross．
Yu Yuan， 27， is deeply interested in this idea． She and her boyfriend have lived in Beijing for many years． And earlier she used to buy things without thinking about them carefully until she saw a video about "zero waste"， in which a family of four placed the rubbish they produced every year in a jar （罐）． After watching the video， Yu wanted to experience this zero﹣waste lifestyle with her boyfriend．
A zero﹣waste life follows the 6R rule﹣Refuse Reduce， Reuse， Repair， Recycle and Rot． Over August﹣October when Yu followed the rule of zero waste 6R， she and her boyfriend Joe Harvey both produced only two cans of rubbish．
Now， the couple have opened a small shop in Beijing， where they use wood products to take the place of plastic ones and cloth bags printed with environmentally friendly logos． Most products sold in the store can be reused． The store also has second﹣hand books and CDs/DVDs with， ideas to make the best of the used things．
"Those who once experienced the non﹣waste lifestyle have slowly changed their ideas，" says Ya， "The zero﹣waste lifestyle is not for ascetics （苦行僧）． It is just around us at our finger﹣tips．" Yu expects some of her friends to join her on the road to zero waste．
（1）Bea Johnson suggests that people should ．
A． try to produce no rubbish in life
B． share objects with others
C． help their friends live comfortably
D． work hard for the Red Cross
（2）We can see from the passage that Yu Yuan ．
A． offers plastic bags in her store
B． is influenced by the 6R rule
C． often buys things she doesn't need
D． likes listening to CDs very much
（3）What Yu Yuan says in the last paragraph probably means that ．
A． lots of people doubt the zero﹣waste lifestyle
B． she feels it hard to continue her lifestyle
C． her friends have followed her lifestyle
D． the zero﹣waste lifestyle is not difficult to live
（4）Which of the following is the best title for the passage？
A． Opening up a second﹣hand store

D． Joining the couple
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.

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．
请将答案写在答题卡上

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．"
