Vicuna，a small town in the north of Chile，is a great place for watching stars all year round.Although it is near the sea，the cold，wet air from the coast does not bring clouds.Instead，dry winds from the desert keep the clouds away at night.In fact，the sky is so clear in Vicuna that it is possible to see many stars that can be seen only with advanced（先进的）instruments in other parts of the world.
In Vicuna，distant（遥远的）star systems such as Magellanic Clouds can be seen without the help of an instrument.That is why the town was chosen as the home of a number of sky observatories（天文台）.One of them，the Mamalluca，is quite different from the typical observatories used by scientists.This observatory was built for tourists who like to look at the stars.During the year，Vicuna's hotels accommodatethousands of tourists who come from all over the world to see the night sky as they have only seen it in books.The cloudless sky is clearly a moneymaker for the town，which plans to set up even more observatories.It was recently decided that building observatories would go on for another few years.
At one point，however，the town faced a serious problem.As the town grew，more streetlights were added，making it more and more difficult to see the stars at night.The town saved the night sky by building a new system of lights that lit up the streets without influencing the view of the sky.

| May 20，2021 Dear Principal， I think the students in our school should wear uniforms.Many schools already have them.Uniforms will help our families save money，since we would have to buy only one or two uniforms for the whole year.Uniforms could also give us more pride in our school.And best of all，if we all wore uniforms，kids wouldn't tease each other about their clothes. I know some students think uniforms are ugly and uncomfortable.But maybe we can pick a uniform that everyone likes.I think this is a wonderful idea for our school. Sincerely， Justin Jones |

One wet，rainy April afternoon Miss O' Shay，the principal，sent for Nancy Lee to stop by her office as school closed.Pupils without umbrellas or raincoats crowded in doorways hoping to make it home between showers.Outside the skies were grey.Nancy Lee's thoughts were suddenly grey，too.
She did not think she had done anything wrong，yet that tight （紧的） little knot came in her throat just the same as she came near Miss O' Shay's door.Perhaps she had banged her locker too often and too hard.Perhaps the note in French she had written to Sallie halfway across the study hall just for fun had never got to Sallie but into Miss O' Shay's hands instead.
She knocked on Miss O' Shay's door.That familiarly solid and competent voice said， "Come in."
Miss O' Shay had a way of making you feel welcome，even if you came to be punished.
"Sit down，Nancy Lee Johnson，" said Miss O' Shay. "I have something to tell you." Nancy Lee sat down."But I must ask you to promise not to tell anyone yet."
"I won't，Miss O' Shay，" Nancy Lee said，wondering what on earth the principal had to say to her.
"You are about to graduate，" Miss O' Shay said. "And we shall miss you.You have been an excellent student，Nancy，and you will not be without honors （荣誉） on the senior list，as I am sure you know."
At that point there was a light knock on the door.Miss O' Shay called out， "Come in，" and Miss Dietrich entered."May I be part of this，too？" she asked，tall and smiling.
"Of course，" Miss O' Shay said."I was just telling Nancy Lee what we thought of her.But I hadn't got around to giving her the news.Perhaps，Miss Dietrich，you'd like to tell her yourself."
Miss Dietrich was always direct."Nancy Lee，" she said， "your picture has won the Artist Club scholarship."
The brown girl's eyes widened，her heart jumped，then her throat tightened again.She tried to smile，but instead tears came to her eyes.
"Dear Nancy Lee，"Miss O' Shay said， "we are so happy for you." The elderly white woman took her hand and shook it warmly while Miss Dietrich smiled with pride.
Nancy Lee must have danced all the way home.She never remembered quite how she got there through the rain.She hoped she had been calm.But certainly she hadn't stopped to tell anybody her secret on the way.Raindrops，smiles，and tears mingled on her brown face.She hoped her mother hadn't yet got home and that the house was empty.

If you walk through a park in the morning or in the evening，you might see a lot of people doing these slow and beautiful movements— Carry the tiger over the mountain and White crane spreads its wings.In fact，they are doing Taichi.
Taichi is an ancient martial art（武术）.It is a common kind of exercise in China.More than 100 million people in over 150 countries practice Taichi at present.Recently UNESCO（联合国教科文组织） has added Taichi to its Intangible Cultural Heritage List（非物质文化遗产名录）.Many taichi fans were happy to hear of it. "This will make taichi more popular around the world.Hopefully，more people will become healthier by practicing it." said Chen Bin.He is a Taichi master from the village of Chenjiagou，Henan Province.This village is the birthplace of Chen﹣style Taichi.
It's true that doing Taichi is good for our health.It can make us walk and move more freely，and it can also make us stronger.During slow movements，we can focus on （专注） our hands and feet.We can control them better.Slow movements also help us to take deep and long breaths.
Taichi also focuses on the harmony（和谐） between yin（阴） and yang（阳）.It shows how the ancient Chinese people saw the world.The world is full of yin and yang：dark and light，soft and hard，female and male.But they don't oppose（对立） each other absolutely（绝对地）.As we see in the picture，a white spot is in the black area and a black spot is in the white area.After a dark night，the sun will rise.Leaves fall in autumn but grow in spring.Everything keeps changing — that is how we should see the world.
Taichi carries traditional Chinese philosophy（哲学），such as being in harmony with nature and using softness to beat hardness.It has become a symbol of Chinese culture.

When your town has winter，the earth's axis（轴） is pointing away from the sun.Your town doesn't get as much light or heat from the sun.The days are shorter and colder.
Winter and summer happen because the earth is tilted（倾斜） as it revolves around the sun.The northern end of the earth's axis points towards the sun in summer.You have more hours of light in summer.Your part of the earth is towards the sun for more hours each day.When the part of the earth where you live is towards the sun，you have hotter days.In winter，when your part of the earth points away from the sun，you have colder days.
You have learned about winter and summer.There are two more seasons in the year.One comes after winter and before summer.The other season comes after summer and before winter.Can you name them？That's right.Spring comes between winter and summer and autumn comes after summer but before winter.
The four seasons are spring，summer，autumn and winter.Spring and autumn are opposite seasons.Which season do you like best？
You have thought about the four seasons of the year.Each season is different.The seasons are made by the northern end of the axis pointing towards or away from the sun.
Your part of the world gets more heat from the sun when the northern end of the axis points to the sun.When the axis points away from the sun，you get less heat.Now you know why winter is colder than summer.The axis is pointing away from the sun in winter.It is pointing towards the sun in summer.

In December 2020， "the Super Apple" appeared at supermarkets across China，sweeter and juicier than usual ones，without pesticide residue（农药残留）.Before reaching the market，the products had been tested over 500 times.Blockchain（区块链） technology in recording farmers' actions is widely used to avoid nonstandard pesticide use.Digital technology at the apple storage helps to group apples，which can keep the stability（稳定性） in the quality. "The future of agriculture lies in the modern technology." Huang Jikun，Professor of the China Centre for Agricultural Policy at Peking University，told Beijing Review.
At China's Central Rural Work Conference in 2020，President Xi stressed that efforts must be made to increase the quality of agriculture.Xi also pointed out the importance of speeding up technologies.
China's agriculture has entered a stage of high﹣quality development，as the country is meeting people's increasing need for high standard products.So agriculture should turn to technology.
Three years ago，Yuan Longping led a program of planting rice in saline﹣alkali（盐碱） soil in areas，including Xinjiang and Heilongjiang.Through hybrid technology，Yuan's team have been able to raise improved rice for saline and alkaline soils.If China could put 6.67 million hectares of saline﹣alkali soil into rice production，it would be very likely to increase by around 30 million tons，a huge contribution to the country.
In Lushui，Yunnan Province，one can rarely see farmers working on the farm.All common tasks are completed automatically（自动化地）.Data（数据） is gathered by the system to improve future production.
"More information and technology centres will be built so that basic data and big data can be improved，and technologies like 5 G and the BeiDou Satellite Navigation System can be used in the field."said Han Fujun，Deputy Chief Engineer of the Information Center of MARA.
Since 2010，the Chinese government has been organizing technology exchanges，training，field trips and other activities for the agricultural technology talents to better understand the situations of each area.
Because of the COVID﹣19，companies begin to rethink better agricultural models，as more people want to eat healthier foods.Science and technology will play a more important role in the future.
（1）Which of the following makes "the Super Apple" sweeter and juicier？
A.The apple storage.
B.The modern technology.
C.The product test.
D.The record of farmers' actions.
（2）From the passage we know that .
A.traditional Chinese agriculture is out of date now
B.farmers will pay less attention to technologies
C.China's agriculture plays a lead role in the world
D.people now need more quality agricultural products
（3）Which of the following is true according to the passage？
A.Yuan's program is a huge contribution to China.
B.Farmers are busy collecting the data in Lushui.
C.5 G and BeiDou system are rarely used in the centres.
D.Talents organize activities to understand each area.
（4）The passage mainly wants to tell us .
A.Yuan Longping is a great Chinese scientist in farming
B.China's agriculture develops fast to meet people's need
C.science and technology improves China's agriculture
D.more agricultural models will appear after COVID﹣19
We are what we eat.From high﹣calorie meals to low﹣fat lunches，much of our health depends on what we eat.We know about the benefits（益处） of eating fittingly for our physical health，but food，and cooking it，is proving to be good for our mental（心理的） health as well.
Some people are now supporting the therapeutic value of cooking food.It's not just about the end result but also the experience someone goes through.Dr Mark Salter，a consultant psychiatrist，told the BBC： "Baking and cooking are good therapies.They help patients develop planning skills，short﹣term memories and social skills—lack（缺乏） of which may lead to mental illness."
TV chef（大厨） and author Nadiya Hussain agrees that cooking is great for helping our mind.She loves to bake and became the champion of the TV show，The Great British Bake Off.She says that "Baking's always been about therapy...It's never really been about the cake." And she thinks that baking is an important tool for our socialization and mental health.
Certainly，creating some delicious food takes our mind off things and gives us something to do，helping us get through the recent lockdown.People have said that mixing dough（生面团）to make bread，for example，has given them a sense of calm and control.Research has shown that doing creative tasks，like cooking，makes us feel happier.Nicole Farmer，who studies how food influences our biology，behavior and mental health，told BBC online that "Cooking represents the human experience of food，and growing people through food，so there is no doubt it can bring us timely positive feelings."
Of course，cooking can be a very sociable activity and sharing the end result，a rewarding experience.Hopefully，as we start to mix with friends and family again，we can enjoy the benefits once more and put us all in the right state of mind.
（1）What is baking in Nadiya Hussain's eyes？
A.It's helpful for our mind.
B.It's a kind of TV programme.
C.It's always about the cake.

（3）Which of the following is right according to the passage？
A.Dr Mark Salter is a consultant psychiatrist of the BBC.
B.Hussain once got the first prize for her books on baking.
C.The Great British Bake Off is a TV show about cooking.

There are only 24 hours in a day，and usually about a third of that is spent sleeping.So is it possible to make use of this time and learn a new skill or even a language？In other words，is sleep learning possible？
Many studies have found that a basic form of learning called conditioning can happen during sleep.In a 2012 study published in the magazine Nature Neuroscience，for example，Israeli researchers found that people can learn to connect sounds with smells during sleep.The scientists played a tone to sleeping study participants while putting some rotten（腐烂的）fish beside their beds.Once awake when hearing the tone.The people held their breath in anticipation of a bad smell.
"This was a dear finding showing participants formed new memories during sleep， " said Andrillon，a scientist in this held.
Although the now memory was implicit （暗示性的），it could influence how people behave，researchers found in a 2014 study published in the Journal of Neuroscience.In that research，after spending a night in a room full of cigarette（香烟） smell mixed with rotten eggs or fish，smokers use fewer cigarettes.
Andrillon and his team members have found that learning in sleep can also go beyond simple conditioning.In their 2017 study published in Nature Communications，participants were able to pick out sound features that they had heard during sleep.
Learning abilities in sleep may spread to learning of words.In a study published in Current Biology，researchers played pairs of made﹣up words and their supposed meanings like "guga" means elephant，to sleep participants.After this，when awake，the participants did better in picking the right translation of made﹣up words in a multi﹣choice test.
So far，research suggests it may be possible to learn about the tone and pronunciation of a language or even the meaning of words while sleeping，although it is to a weaker level than what we do during the day without noticing.
（1）What is the main purpose of the text？
A.To show that sleep learning is possible.
B.To study how to make use of sleep learning.
C.To report some famous research findings.
D.To prove sleep learning is implicit and weak.
（2）What does the phrase ''new memories'' in the third paragraph refer to（指的是）？
A.Connection between participants and scientists.
B.Connection between sounds and smells.

In the Spring and Autumn period （475 ﹣ 221 BC） there lived a man called Ji Zha.He was the fourth son of the king of the Kingdom of Wu.Because of Ji Zha's sticking to righteousness（正义）and wide learning，he was his father's favorite and the king wanted to make him his heir（堆承人）.However，Ji Zha refused because he thought the king's eldest son should be the one to receive the throne.Later，Ji Zha served as an ambassador（外交大臣） of Wu to other kingdoms in China.
Once，on a mission to the Kingdom of Lu，Ji Zha passed through the Kingdom of Xu.The king of Xu received him as a friend，and admired the valuable sword（剑） Ji Zha was wearing.Although his host didn't mention it，Ji Zha could see he wanted to own it very much.However，as he still needed to go to Lu，Ji Zha didn't give the king of Xu his sword as a present.
After finishing his mission to Lu，on his way back，Ji Zha once again passed through Xu.This time he decided to give the sword to the king of Xu.But when he arrived，his friend had already passed away.Ji Zha didn't expect it and felt very sad.He took off his sword and gave it to the dead man by hanging it on a tree near his tomb（坟墓）.
Ji Zha's attendants （随从）didn't understand his action，saying， "Sir，the king of Xu is already dead.Why do you still give up your sword to him？ "
Ji Zha shook his head， "When I came to the Kingdom of Xu last time，I noticed that my friend admired my sword and I decided that when I came back I would give it to him.However，I never expected this turn of events.But how could I change my mind just because the man had died？" With these words，he left the place，low﹣spirited and heart﹣broken.

What do you do with your rubbish？Throw it out？You don't know what you're missing!Look closely at the two figures on your left.They were made from things most people throw away.The figures were made from used bottle caps.Those two bottle﹣cap figures were exhibited （展示） in a museum.
Folk art is art made by common people who have not been trained as artists.Their work is often based on traditions in their culture.Fine art，on the other hand，is usually made by people who have had training in art.Works of fine art are valued for their artistic beauty.They are supposed to be looked at but not used.Works of folk art，however，are often made for everyday use.
There were more than 800 pieces of folk art from nearly 50 countries in the exhibition.All of the pieces were made from used metal，wood，cloth，and plastic.The artists come from many different cultures.Still，they all share one thing.They take objects that are normally thrown away and change them into objects that are beautiful，useful，and fun.The artists may not think of what they do as recycling，but that's exactly what it is.Fine artists might work with expensive materials.They might use expensive tools to shape these materials into works of art.On the other hand，in poor countries rubbish might be the only material folk artists and toy makers can afford.The exhibition shows that a rich imagination is very important when there are only poor materials.Recycled art began long before people began to think about recycling.Some of the objects in the exhibition date from the 1930s.
Even if you don't create art out of rubbish，it's good to save our natural resources.Remember the three rules：reduce，reuse，recycle.If you reduce waste，true things instead of throwing them out，and recycle materials such as paper，plastic，and glass，you will protect the environment.
