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．

Do you know about Psephurus gladius？ It's a Chinese paddlefish known as "king of all national freshwater fish"． However， it is announced that the Chinese paddlefish living in the Yangtze River has become extinct （灭绝的）．
A paper from Science of the Total Environment shows that the largest freshwater fish in China might have gone extinct between 2005 and 2010． Wei Qiwei， author of the paper， said in September， 2019， some experts supposed that the first﹣class protected fish had been extinct already．
The Chinese paddlefish was about 2 to 3 meters long and could grow longer than 7 meters．The fish had lived on the earth for 15 million years． The latest discovery of the fish was made in 03． Scientists helped the fish to return and tried to track （追踪） it． Unluckily， a boat accident
caused the tracking efforts to fail． Since then， no discovery has been reported and no such fish has been kept in captivity （圈养）．
"The Chinese paddlefish was so big that it was hard to raise in captivity，" Wei said．Between 1984 and 1993， he once tried to save four fish， but only one stayed alive and returned to the river．
The extinction of the fish has called public attention as people expressed sadness over the death，hoping such animals would be better protected so that future generations could see them．From Jan 1， 2020， China began a l0﹣year fishing ban （禁令） on important areas of the Yangtze River to protect Biodiversity （生态多样性） in China's longest river．
（1）It can be learned from the passage that ．
A． the Chinese paddlefish was hunted too much in the past
B． the Chinese paddlefish was the largest freshwater fish in the world
C． the Chinese paddlefish could grow to be over 7 meters in length
D． the Chinese paddlefish has never been seen so far
（2）What happened after the boat accident mentioned in Paragraph 3？
A． Some scientists saved the fish．
B． People failed to track the fish．
C． The fish lost its life．
D． The fish was kept in captivity．
（3）Why couldn't the Chinese paddlefish be raised in captivity？
A． Because of its living habits．
B． Because of its large size．
C． Because of its special diet．
D． Because of the high cost．
（4）What's the writer's purpose in writing the passage？
A． To show people 's sadness about the fish's death．
B． To explain how the fish died out．
C． To call on people to protect animals．
D． To introduce a first﹣class protected fish．
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．
（1）We can learn from Paragraph 1 that ．
A． the Arctic is the last really clean place left on earth
B． the Arctic is an icy land of pure white snow
C． the Arctic is a beautiful icy land with clean air
D． the Arctic has been polluted by plastic rubbish
（2）The underlined word "contribute" means " " in Chinese．

D． 是……原因之一
（3）Where do most of the microplastics in the snow come from？
A． From water．
B． From air．
C． From wind．
D． From food．
（4）Which of the following isn't true？
A． We may breathe microplastics in Arctic．
B． Microplastics may cause lung cancer．
C． We don't have to mind microplastics right now．
D． Microplastics have hurt ecosystems．
（5）How does the writer end this passage？

Fresh green grass． Hundreds of colorful wild flowers． Water running into little pools． Birds making their homes in boxes． The 9， 500﹣square﹣metre Augustenborg Botanical Garden may look just like any other well﹣organized park but there's a difference． It lies on the roofs（屋顶） of industria land office buildings in the city of Malmo in Sweden．
Green roofs are not a new invention． And now they are getting popular again． The common roofs of a modern city have endless black surfaces with no life or water． Perhaps that's why a garden on a roof becomes such a perfect choice for more and more people．
Green roofs are not just pretty． They also help to moderate the city temperature． The high temperatures on common roofs in the summer can make top floor flats uncomfortably hot． What is more， they play a part in making the cities hotter than the countryside around them， causing the "urban heat﹣island effect"． On a green roof， however， with its plants and water， temperatures change only a little， as they do in a park． This can greatly cut the costs of heating and cooling in the building below．
Also， a green roof takes in rain water， and protects the city drainage（排水） system．_____ And small animals and birds can make their homes on it． Thanks to this， the city may become part of nature， rather than something completely separate from it．
While the cost of building such a roof can still be higher， it can be cheaper in the long term as a result of energy savings． And wouldn't it be wonderful to be able to walk out into a garden high above the city's noise and traffic， whether you're at school or in an office or just at home in a ten﹣floor block．
（1）With the example of Augustenborg Botanical Garden， the writer wants to explain ．
A． how wildlife is protected

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

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
B． Recycling waste
C． Saving the environment
D． Joining the couple
The world has a plastics problem． And not just with bottles． Straws（吸管）， toothbrushes， toys﹣all kinds of plastics are placed in landfills． There are 5 billion tons of plastic waste in the world． Landfills have a large part of it． By 2050， they could have 13 billion tons．
Much of plastic rubbish finds its way into the ocean． Scientists say 165 million tons of plastic pieces are floating around out there． And most plastic won't disappear itself． It will remain in the ocean forever． Whales get caught in plastic fishing nets． Birds die because of eating plastic straws and bottle caps． It endangers ocean life． Plastic rubbish even ends up in the food we eat．
Governments are realizing that recycling may not be enough． They are taking more actions． Though it is hard work， it is still a solvable problem． In Britain， people are not allowed to use plastic bags except in hospitals． Scotland and several coastal cities in the US stop people from using plastic straws as well． The US alone throws away some 500 million plastic straws a day． That's enough to circle the Earth twice． "Saying no to a plastic straw is an easy way to make a big difference，" Dana Lofflin who started said． "Do we really want to pass on to our children a world harmed by plastic？"
People have found some tasty ways to reduce waste． A company in India made the first﹣ever spoon that people can eat． You don't have to eat the spoon． You can throw it away． It decomposes（分解） in just a few days． David Edwards， a scientist at Harvard University， designed an eatable bag which can protect the food or drink inside． It is a delicious replacement for plastic ones．
（1）According to the write， birds die because they ．

Populations of white﹣tailed deer（白尾鹿） are growing rapidly in many parts of the United States． As populations grow， food becomes a problem． Many deer die of hunger．Others grow up small and unhealthy． In search of food， hungry deer move closer to where humans live． They eat farm crops， vegetables and even trees． Besides， increased numbers of deer near roads can cause traffic accidents．
People admire the grace and fast speed of deer． Most people don't want these animals to be hungry and ill． Should people take action to control the growing deer populations？
Should People Take Direct Action？
Many people think that hunting （打猎） is the best way to control the animal populations． Wildlife managers will see if there's enough food in an area and decide its carrying capacity（容量）． Then hunters with licenses are sent to help control the number of deer． Hunting is usually not allowed in cities or suburbs， however．
Some people have the idea to catch the deer and move them to other places． But this method is expensive and requires finding another place that can accept the deer without breaking the balance of ecosystem．
Scientists are also working to develop chemicals to control the birth rate in deer populations． But this plan works for only one year at a time．
Should People Take Indirect Action？
Some suggest bringing in natural enemies of deer， such as wolves， lions and bears， to areas with too many deer． But these animals could also hurt dogs， cats， and even humans．Other communities have built tall fences around areas to keep out the deer．However， this is impossible for farmers．
Some people are against any kind of action， They support leaving the deer alone．Animal populations in an area naturally go up and down over time． Doing nothing means that some deer will die of hunger or illness． But finally， the population will reach a size within the carrying capacity of the environment．So， let nature go its own way．
（1）According to the passage， increased numbers of deer can bring to people in the area．
A． water pollution
B． traffic accidents
C． serious illnesses
D． growing populations
（2）Which of the following is the best to fill in the " " in the passage？
A． Should People do Nothing？
B． Should People protect the Deer？
C． Should People Take Special Action？
D． Should People Drive the Deer Away？
（3）The writer most probably agrees that ．
A． farmers can build fences to keep the deer out
B． people should leave the deer alone in the wild
C． hunting is the best way to control the deer populations
D． it's great to catch the deer and move them to other places
（4）The writer organizes this passage by ．
A．telling stories
B．using numbers
C．giving opinions
D．describing scenes
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．
（1）Where does Marjorie Woodruff work？
（2）How long does it take for apple remains to rot？
（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？
Protecting the earth is like protecting our eyes．People's attention to recycling is increasing．From recycling plastic bags to using environment friendly products，there are many developments to be seen in almost every comer of the world．
Sweden is a worldwide leader in recycling．They open world's first mall for repaired and recycled goods，It's called ReTuna，a two﹣story building in Eskilstuna，Sweden，about 70 miles west of Stockholm．The clever thing about this mall is its position．It's right next to the city's recycling centre．So a stream of cars is already coming to drop off unwanted household things．This produces a supply of things for the shops．There are 14 special shops．When goods arrive，a team sorts everything into categories（类别）．The mall only sells goods that are recycled or"upcycled"，meaning unwanted things broken down and reinvented as something new．By doing so，50 new jobs were created in repair and retail（零售）
"You can come and just do sustainable shopping and Sweden loves it．And the world loves it，"said Anna Bergstrom，the manager of the ReTuna Mall．"I think it's fun to find something that people have used，and we can use further，"said Cato Limas，a ReTuna customer（顾客）．"If you look at the things they're selling here，they're almost new．So actually，why do you need to buy new things？"
These unwanted things found new homes．In 2018，the mall sold second﹣hand goods worth 1.3million．

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？

When he was nine years old，an American bey called Milo Cress had a question：How many plastic straws（吸管）do Americans use every day？
He quickly learned there wasn't a simple answer．The boy tried to find it out himself．Through lots of research，Cress found out that Americans use about 500 million straws every day．In hopes of cutting down plastic waste，he founded the Be Straw Free project in 2011．
Cress started the project in his hometown Burlington． Vermont． He asked a local restaurant to stop offering straws with every drink order． It was a simple change． However， it would save money．And by doing that， the restaurant would cut down on its straw use by 50 percent．
For the year that followed， Cress tried to spread his proicct across the United States． More and more restaurants agreed to join． They stop providing the customer with a straw unless he or she asks for one． Last April， Seattle became the first American city to completely ban plastic straws．
After his project became popular， Cress took his findings on the road． He has spoken to tens of thousands of students around the world． He wants to encourage more people to say no to plastic straws．

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．
