Fifty years ago, China successfully launched its first satellite, Dongfanghong 1, and started new chapter in space exploration. ( mark ) its 50th anniversary, the China National Space Administration announced the name for the country's Mars planetary exploration program on April 24.

The mission, Tianwen got its name from a long poem Tianwen  ( write ) by Qu Yuan, a famous poet of the Warring States Period. In the poem, Qu raised a series of questions( concern ) the sky, stars, natural phenomena, myths and the real world, reflecting his doubts on traditional ideas  his pursuit of truth. 

So far, China (make ) remarkable progress in space exploration. In 1970, China launched its first man-made Earth satellite, becoming the fifth country in the world to launch man-made satellites ( independent ) . Over the past few years, China's missions, including the Shenzhou and Change series were designed to explore outer space, expanded ( mankind ) understanding of Earth and the universe.

This time, the Tianwen series will carry out the first Mars exploration mission, represents a milestone for China's move toward deep space.

With the names deep roots in Chinese traditional culture, Tianwen demonstrates the  (determine) and perseverance of Chinese people to move further into deep space. 

I will never forget the adventure I had last summer. It all started when my friends and I decided to go on a camping trip deep in the forest. We were excited to 1  the wilderness and spend time away from our busy lives. 

As we set up our tents, we noticed a strange sound coming from the trees. 2 , we heard a loud roar and saw a huge bear 3  toward us! We quickly 4  our bags and ran as fast as we could to escape the danger. 

After running for several minutes, we 5  we were lost in the woods. Our phones had no signal, and we had no idea how to get back to our campsite. As night fell, we made a 6  to keep warm and tried to come up with a plan. 

Just when we thought things couldn't get any worse, we heard another sound. This time it was a group of wolves howling in the distance. We knew we had to stay 7 and keep the fire going to 8 them off.

The next morning, we decided to 9  a nearby stream, hoping it would lead us back to 10 . After hours of walking, we 11  a ranger station. The ranger (守林员) was surprised to see us and offered to help us find our way back to our campsite. 

We were so 12  when we finally made it back to our tents. Despite the danger and 13  we faced, we were grateful for the experience and the memories we created together. 

The adventure taught me the importance of being prepared and staying calm in 14  situations. It also 15  me of the beauty and power of nature, which we should always respect and appreciate. 

Daily Habits of Naturally Productive People

When it comes to being more efficient at your job, you know the basics. But research shows a whole new side of productivity you may not have realized. 

Focus on being happier.

 Even if a low mood does not completely disable you from functioning, it can decrease your productivity to make you far less efficient. Also, don't hesitate to seek help. This will not only help you achieve a more stable work-life balance, but a new outlook can also open you up to new opportunities and necessary changes. 

Prioritize fitness.

You know the countless benefits of exercise. Even 30-minute bursts of moderate-to-high physical activity just three to four times a day can go a long way in helping you accomplish your personal and professional goals. If you're really not a fan of the gym, join a group class to keep yourself motivated. 

Pressing pause is important. Studies show that prolonged tasks that require high levels of focus, energy, and attention can cause you to become less productive and focused over time. Take brief mental breaks. When we take 'health breaks' we are much more focused and engaged for our next work, in contrast, when we try to work continually on a project without breaks our quality of work tends to deteriorate. 

Don't try to do everything at once.

People believe the more we can do at once, the better.  In fact, the more we multitask, the less efficient and productive we become. Instead, to increase productivity, focus on one task at a time until it's completed and then give all of your attention to the next task. 

A. Make productivity first. 

B. Take breaks at times. 

C. However, research shows the opposite. 

D. Studies found happier people are more productive. 

E. It improves your mood and increase your brain's productivity. 

F. Have a look at these habits of naturally productive people. 

G. Researches show that daylight exposure improves your levels of activity. 

With the invention of the Internet, humanity is now experiencing an adventure toward technological advancement. Nowadays, technology assists us with everyday tasks such as driving, grocery shopping and even dating. Technology is so closely connected to our lives that it's easy to overlook one important question: When technology really starts to control the world around us, what comes next?

Many experts and workers are scared that automation will take jobs from people who need them and give those jobs to robots. I understand their concern. However, if robots are outperforming us at our jobs, then what do humans have left to offer? We have the emotions and imagination that make us human. A machine might work faster than a person, but that's because humans built the machines that way. That, itself, is an amazing accomplishment of the human imagination. We are talented, passionate creatures, who do not deserve to be trapped in miserable jobs anymore!

By now, I hope you're curious to hear which occupations we should focus on in the future. The obvious answer is jobs in technology and robotics. Tech-related jobs will continue to be in big demand, and people who work in these fields will continue to become more important. We should be grateful to them for doing work to take us higher as a society. Besides, we should also focus on jobs in the arts and entertainment. It may sound crazy, but what could better reflect the creativity of the human mind than the arts? I believe technology has opened up our world, allowing us to share our imaginations with everyone!

So, we must ensure that future generations know that we mean it when we say, "follow your dreams. " Welcome to the 21st century: what a time to be alive! There has never been a better time to be yourself, and I can only see it getting even better from here.

Did you ever want to see Big Ben, Houses of Parliament, Westminster Abbey in 15 minutes? Then BA London Eye is the one for you. 

British Airways London Eye, formerly called as the Millennium Wheel, is situated on the south bank of the River Thames on the Jubilee Gardens. It is situated between Westminster Bridge and Hungerford Footbridge in Lambeth and adjacent to (比邻) Old Country Building. It stands opposite to Houses of Parliament. 

It started with a vision of Architect couple David Marks and Julia Barfields, who had competed for millennium ideas contest conducted by Sunday Times, a British newspaper in 1993 to welcome year 2000 splendidly. Regrettably, the contest was scrapped, but the couple persisted with their dream project by forming a company for this undertaking, eventually grabbing the attention of Evening Standard, another British newspaper. British Airways, after noticing this widely publicized article, agreed to fund, foreseeing the vital contribution of this project to London's skyline and its tourism, giving a spectacular view of this fascinating city that was otherwise not visible to the Londoners.

The entire construction resembles a giant cycle wheel, with a diameter of 135m (443ft) and weighing 1,700 tons of steel and 2,000 tons at the foundation reaching almost 30m deep! It is the largest observation wheel built so far, making even Statue of Liberty, Big Ben, St. Paul's Cathedral, look up to it. It is the 4th highest structure in London. Canary Wharf Towers, BT Tower and Tower 42 are the higher three.

The whole structure was designed in parts in various countries, later fully assembled on Thames bank. With the dedication of 1,700 workers, this structure was realized in 16 months, just in time to welcome the millennium. Tony Blair inaugurated (为……举行开幕式) it on December 31^st, 1999 and a minor safety concern regarding clutching delayed its opening to public, which finally happened 3 months behind the schedule in March 2000. 

In February, Dr. Robert Lefkowitz published a memoir (回忆录) called A Funny Thing Happened on the Way to Stockholm: The Adrenaline-Fueled Adventures of an Accidental Scientist. As a physician and biochemist, Lefkowitz is a professor of biochemistry and chemistry at the Duke University Medical Center in Durham, North Carolina. 

In a recent conversation via video, Lefkowitz said that he wanted his memoir to be "funny, interesting, and easy to understand". In the book, Lefkowitz humorously describes his Journey from a cardiologist (or a heart doctor) to a biochemist.

Lefkowitz's dream of becoming a doctor began when he was eight years old and growing up in the Bronx of New York City. After his father died of a heart attack, Lefkowitz made up his mind to be a cardiologist. He earned his medical degree at Columbia University.

Lefkowitz is no stranger to conducting experiments and making discoveries. He was awarded the 2012 Nobel Prize for Chemistry with Brian Kobilka. The two scientists were honored for their discoveries that could help unlock the secrets of many diseases. 

When asked what played the most important role in his success, Lefkowitz mentioned about himself and he described himself as "reasonably intelligent and creative, hardworking, and not easily disturbed". He added that being funny could also be very good for you and the people around you.

Before winning the Nobel Prize, Lefkowitz did countless experiments, and only 1 out of 50 turned out OK. "With difficult decisions I've had to make, I tend to make them with my heart rather than my head. " Lefkowitz said. "However, I don't mean that deciding with your heart is always right. "

At age 78, the scientist has no plans for slowing down. "My body and mind are still working," he said. "I want to continue running my lab at Duke University and writing and publishing research papers. "

It was the golden season. I could see the4 leaves floating with the cool wind. In such a season,I liked walking alone in the leaves,5 to the sound of them. 

Autumn is a harvest season and life is uninteresting. The boring days always get me6 . But one day, the sound of a violin flowed into my ears like a stream（小溪） flowing in the mountains. I was so surprised that I jumped to see what it was. A young girl, standing in the wind,was7 in playing her violin. 

I had8 seen her before. The music was so nice that I listened quietly. Lost in the music,I didn't know that I had been9 there for so long but my existence（存在） did not seem to disturb her.

Leaves were still falling. Every day10 she played the violin in the corner of the building I went downstairs to watch her performance. I was the only listener . The autumn seemed no longer lonely and life became11 . Though we didn't know each other, I thought we were already good friends. I believe she also loved me.

"14 it was your playing that gave me a meaningful autumn,"I answered,"Let's be friends. "The girl smiled, and so did I.

I never heard her play again in my life. I no longer went downstairs to listen like before. Only Thick leaves were left behind. But I will always remember the fine15 of the girl. She is like a dream-so short, so bright, like a shooting star giving off so much light that it makes the autumn beautiful. 

How to Be Fruitful During Hard Times

When we are fighting tooth and nail, or when we have difficulty concentrating, we may turn to others for help. We may even wish we had a hero to help us. Well, today here is some advice for you. 

Turn ourselves into our own heroes.

When we make ourselves heroes, we not only gain focus but also a sense of purpose. For example, it can give us hope as stories in the books often do. In stories, writers often give their hero, the main person in the story, a purpose. 

Write out our tasks and ideas.

In stories, heroes also have tasks, which they want to finish, and ideas, which they see for themselves. So we can write out our tasks and ideas, not just for a project but for our life as well. With clear tasks and ideas, events. in our life no longer seem to be separate events. There's just a lot of value in having tasks and ideas.

When we know our strengths, we can use them fully. In difficult times, we can make our life easier by focusing on our strengths. It is even more important to identify weaknesses. All heroes have them. On their journey they face their weaknesses and learn from them. 

Have small goals within a larger goal.

As we know, the hero's journey is not a one-time thing. It is a journey we are on in our entire life. Our life's journey is ongoing and ever-changing. We should be realistic with our goals and to be kind to ourselves, especially during difficult times.

A. Learn from heroes in stories. 

B. Know our strengths and weaknesses. 

C. We often live a life without purpose. 

D. They become part of our larger stories. 

E. So have small goals that we can measure in some way. 

F. We can do the same for ourselves and identify our purposes. 

G. Making ourselves the heroes in our own stories helps us in many ways. 

Dunhuang Academy together with Huawei launched a brand-new technology-drive n tour experience at the Mogao Grottoes on the evening of April 

8. Using Huawei's newly-released Hetu artificial intelligence platform, coupled with the output of the Digital Dunhuang project, visitors to the Mogao Grottoes can enjoy a fantasy experience prior to entering the attraction.

Zhao Shengliang, director of the Dunhuang Acadcmy, said that it has been cooperating with Huawei since March 2019. Using Huawei's latest Hetu technology, visitors are able to see the detailed contents of the Dunhuang Art Murals（壁画） outside the caves, through their Huawei mobile phones. This will reduce the time tourists spend inside the cave, aiding the protection of the cultural relics, while at the same time helping to increase the amount of information yisitors can obtain. It is also considered to be a new way of promoting Dunhuang Art.

The Dunhuang Academy has used digital technology to preserve the research and exploration of Dunhuang Grottoes since the early 1990s. It has collected a wealth of data and has realized the goal of sharing of digital Dunhuang globally. It has played an important role in the protection and research of cultural site, as well as promoting the development and progress of related work. 

The Huawei Hetu platform unites Dunhuang's study findings, high-resolution images of the site's murals and virtual, three-dimensional models with the real Mogao Grottoes. It has not only re-created the real tour of the scenic spot, but also developed a new way of digitally experiencing the grottoes. When people visit the site, they not only have the experience of seeing the real grottoes, but they can appreciate the admirable artworks more clearly and in greater detail.

In the future, Dunhuang Academy will continue to cooperate with Huawei to create more colorful virtual content to enrich the experience of Mogao Art on the platform, helping people around the world get to know Dunhuang Art better. 

Not Even Wrong

My eight-year-old son, lack, is a boy with autism（孤独症）. Even though I always hear from others that he is very bright and he is making enough progress to meet goals, I am still anxious walking into their parents' meetings.

Last fall's parents' meeting was even worse for me. I noticed Jack making a great effort to keep up with others. Some parents watched Jack and whispered（窃窃私语） and no children were willing to play with him. I started to see the social divide between Jack and his peers（同龄人） widening.

After the parents' meeting, his teacher spent long time talking to me. She told me that it was getting more difficult for Jack to meet goals just because he was bright. Some teachers and students always complained（抱怨）about Jack's actions. She also advised me to think about whether the normal class was the best setting for him. Hearing these words, I was very upset.

Then she blew my mind. She showed me one example of Jack's works and said,"I didn't know how to grade this. It's not oven wrong, but it's not right. "I grasped when she said"not even wrong",which is the name of one of my favorite books on autism, by Paul Collins. The book says a girl whose idea is so far off base but it is not even wrong. It perfectly describes autism and it perfectly describes Jack.

In his book, Paul Collins wrote,"Children with autism are like the square pegs（钉,桩）. Hitting a square peg into a round hole is hard work. What's worse, it's destroying the square pegs. "

As a mother of a boy with autism, I want to help find more square holes. I want this world to be a world where it is okay to be a square peg without having to pretend to be round. We have been hammering（锤打） square pegs into round holes for a long time. Now we should put down the hammers. And I hope that some of those kids told their parents. And I hope that some of you read this and tell your kids. And I hope that we, all of us together, CAN change the world.
