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.

A new contact lens（隐形眼镜片）has been developed by scientists from America，Britain and China.It can check for illnesses at any time by examining chemicals in tears.A new sensor（感应器）is used to achieve his purpose.
Scientists hope that the improvement could help to deal with sudden medical events.Dr.Zhao Yunlong said， "COVID﹣19 has had a great influence on the scientific world.And we are doing research to help people deal with similar events in the future."
When introducing the new contact lens，Dr.Guo Shiqi，a researcher at Harvard，said，"In the past，the sensor was put between the layers（层）of the lens.It didn't have direct contact（接触）with tears，But our new sensor is smaller and smarter.I t can be fixed to a lens and keep direct contact with tears.What's more，it causes no discomfort to the eye.
The contact lens has not been put to the market，but researchers are quite sure that it will be welcomed.It is especially useful for the old and those who may experience sudden medical events.
As society develops，scientists are supposed to develop more products that provide care and convenience（便利）for people.The contact lens is one of what they are researching on.Earlier，a California company developed another kind of contact lens using LED technology.It can show the heath information on the mobile phone.Steve Sinclair，head of the company，said， "We have to build something that helps you when you need it and stays of when you don't need it."

When Yi Xiaoyang was two，he fell in love with skiing（滑雪）.His first time on snow，however，wasn't successful.He slept on the ski lift until the coach found him.He started to learn how to ski from then on.Yi was a fast learner，and at the age of six，he began to ski in other parts of the world.
In 2015，Beijing got the chance to hold the 2022 Winter Olympic Games.Yi felt it hopeful to take part in the Olympics.He decided to take training courses like a professional athlete（职业运动员）.
As a student，Yi has to take classes like others.At the same time，he has to train full day on weekends and half day on Tuesday，Wednesday and Thursday.In summer，the training goes on.
At the beginning，that was a big challenge（挑战）. "When I started to train like an athlete，everything seemed to change， "said Yi， "I lost my interest.I even got angry with my coaches.They talked to my parents and decided to give me a one﹣week break from training. "
Luckily，during that break，he picked up his joy in skiing. "I found that skiing had already become one important part of me， "said Yi.After that，he moved back on his fight for his dreams.

Historically，most cars have run on gasoline（汽油），but that may change in the future：cars can also run on other liquid fuels（液体燃料）and electricity.
Gasoline is from oil.The energy in gasoline comes from hydrocarbons（碳氢化合物）.Gasoline provides great power for cars.However，it causes environmental problems，like air pollution and temperature rise.So gasoline can't be the best fuel.
Another choice is electricity.Electricity cars can be as efficient（效能好的）as cars using gasoline，And they produce less pollution.But electric cars themselves are more expensive.Good news is that the cost has been lower and there are more and more places for the cars to get electricity ever since 2010.
The other choices are other liquid fuels.Many of these can be stored in the same places as gasoline，and used in the same cars.They can also be friendly to the environment.
One way to make such fuels is to get CO 2from the air and put it in water.Through chemical reaction，hydrocarbons can be created.However，these fuels take up more space.
Another way is to make such fuels from plants which take in carbon from the air.These fuels are greener in use.But not all of them can be as efficient as gasoline.
For a fuel to be the best，people have to be able to afford it.Unluckily，almost every green technology is more expensive than that of using gasoline.Governments and car producers are doing everything they car to cut down the costs.In the end，the best fuel will be both affordable for car users and green for our planet.

Newspapers are dying.Electronic devices like mobile phones，pads，TVs and car radios can all be the killers.Most people believe in the long run，there is no reason• no practical reason for newspapers to survive.No matter what we do may only buy time.
Can anything save newspapers？I decided to have a try.
Many years ago，Bonnier，a Swedish publisher，set a newspaper in the former Soviet countries .After a few years，they had more newspapers in central and eastern Europe.However，these newspapers were run by a group of inexperienced people，and they didn't have enough money.In many places there were not even art directors.
I got a position in Bonnier's newspaper as an art director.
It was very difficult at first.I was really disappointed，until one day，in Londonn，when I saw performance by Cirque du Soleil. "These guys took some run﹣down entertainment，and put it to the highest possible level of performance art.M Inspiration lighted me up， "Why can't we do the same with the newspapers.We started to redesign the newspapers，one by one.
We used our imagination.We treated the whole newspaper as one piece，one composition - like music.
Music has a rhythm，has ups and downs.Design is responsible for this experience.Flipping through pages was readers' experience and I was responsible for this experience.
The front page became my personal channel to talk to the readers.My approach was simple and direct.I wanted to show my understanding of art，and of reality.I wanted to make posters，not newspapers.Not even magazines：posters.
We had determination，and we kept on trying.We experimented with type，with illustration and with photos.We kept asking：Why do we do it？What's our goal？
Design was not only about the front page.It was a part of the process.To be good was not enough.The process we made was about improving the product completely.
We adjusted the content accordingly.We improved everything to what our readers thought it should be and how they liked reading it.We kept improving and we had fun.
Soon in Poland ，our pages were named "Covers of the Year" three times in a row.One year later this newspaper，in the same country，they named it the "World's Best﹣Designed Newspaper".Two years later，the same award came to Estonia.The circulation of the newspapers kept going up.They became more and more popular.
Someone may think we are buying time，but our newspapers are alive，and growing.

Most viruses can be found and killed by our immune system as soon as they enter our bodies.However，some viruses，for example，the coronavirus，are sneaky.They are difficult to recognize and find.These viruses can cause deadly diseases，like COVID﹣19.Human﹣to﹣human transmission can easily occur，and pandemic will therefore break out.Vaccination is by now a simple，safe and effective way to protect us from the diseases.
▲Vaccines are something that "looks" exactly the same as the viruses，mainly made from the viruses that are weakened or killed.They will not make us really ill.They only stimulate and activate our immune system to work，telling it something harmful is coming in.The immune system will know what the "viruses" look like，and send B cells（lymphocytes）or antibodies to find and kill them.Meanwhile，B cells will remember them for the next kill.A vaccine may also give us passive immunity by providing B cells taken from an animal or a human to play the same role.
Scientists have developed more than 180 vaccines to fight against COVID49.The technical approaches of these vaccines can be a little different，but their aims are the same.
Take the inactivated vaccine as an example.In an inactivated vaccine，the coronaviruses are already killed or made into the ones unable to produce more new viruses.When the immune system "sees" them，it will try to kill them.The question is：without enough these viruses• how can B cells remember them？That's why we need to take the vaccine more than one time.Though this vaccine is safe，it might not be as effective as it is expected to be.
The live﹣attenuated vaccine is different.In this vaccine，the viruses are weakened，but they are alive.They can produce enough new viruses to train the immune system to kill and remember them，so people only need to take the vaccine once.The live﹣attenuated vaccine is considered the most effective，but there is a worry：what might happen once these viruses wake up？
Therefore，although vaccination is by now one of the best ways to protect us from COVID﹣19，it can be better.
（1）The coronavirus can .
| A． |
not be killed |
| B． |
not be found |
| C． |
cause deaths |
| D． |
stop pandemic |
（2）Which of the following can be the best topic sentence of Paragraph 2？
| A． |
Vaccination can provide us with B cells. |
| B． |
Vaccines are made from different viruses. |
| C． |
Vaccination can prepare us against viruses. |
| D． |
Vaccines won't make us ill as the viruses do. |
（3）Compared to the inactivated vaccine，the live﹣attenuated vaccine .
| A． |
needs taking more than once |
| B． |
is equally safe |
| C． |
contains viruses that are killed |
| D． |
is more effective |
（4）What can we learn from the passage？
| A． |
Vaccination is good enough to treat COVID﹣19. |
| B． |
The immune system can be more effective with vaccines. |
| C． |
The viruses in inactivated vaccines can make new viruses. |
| D． |
180 vaccines have been developed to fight against diseases. |
Lima，the capital of Peru，is located in the central coastal part of the country，overlooking the Pacific Ocean.With a population of more than 9 million，Lima is one of the largest cities and the only capital in South America that faces the ocean.
Lima has a long history.The lost Inca civilization ，is thought to be a mystery.There are many museums，where you can learn：how the ancient American Indians founded the Inca Empire and built Machu Picchu，a famous ancient city in the Andes Mountains；what happened in 1532 and why over 90% of Peruvians speak Spanish.Visiting the historic center，a World Heritage Site you may find you are communicating with both the past and the present.
Lima is also a place where you can find the lifestyles and fashions，created by its people and culture.You will see Peruvian clothes，dances，and taste their delicious foods and drinks.You can see buildings in different styles，enjoy the fantastic sunset over the ancient ruins，climb the mountains，fly over the ocean，or sit in the restaurants and bars to experience Peruvians' relaxing life.
You may have heard "It never rains in Lima. " In fact，the special geographic feature makes it not as dry as it is said to be and it is warm all year round.Though it seldom rains in summer，it sometimes drizzles on early winter mornings.The drizzleand the wet air "water" the ground，which makes the crops and the plants grow.Moreover，modern technology helps to bring water from the snow and ice on the top of the Andes （over 6，000 m high）for the city to use.People there never waste water.
Lima is such an amazing city that it is worth a visit.
