A small cloud moves slowly through the air in a hospital operating room （手术室）.In the room a patient with cancer（癌症），lies on a table.The cloud is all around the patient，covering her body and filling her lungs（肺）.The cloud is not smoke.It is made of millions of nano﹣robots（纳米机器人）.These tiny robots move from cell （细胞） to cell in the patient's body，killing the cancer.
Fighting cancer with nano﹣robots is only an idea today，but scientists say that it could be possible in the future.Using nano﹣robots for good purposes such as fighting the illness or repairing the environment may be the way to many of today's problems.
However，nano﹣robots could be a dangerous risk as well.Because nano﹣robots are so tiny，they will have to work in large teams of many thousands to many millions.For this reason，nano﹣robots will have to be programmed（被编程）to build themselves.Scientists will not have the ability to build millions of nano﹣robots one by one.
This ability to re﹣produce is making some scientists worried.What will happen if something goes wrong in the programming？Quite a lot of crazy nano﹣robots would be far worse than any illness.Some people think that if they get out of control，nano﹣robots could make the Earth gone.
What should be done？Should we continue researching nano﹣robots or should we search for other methods？This is one of the many difficult decisions that we have to make in the future.

A Pioneer for all People
Though he was one of China's most famous scientists，Yuan Longping considered himself a farmer，because he worked the land to do his research.
Known as "Father of Hybrid Rice （杂交水稻）"，Dr Yuan graduated from Southwest Agricultural （农业的） College in 1953.From then on，finding ways to grow more rice was his life goal.As a young man，he saw the great need for increasing the rice production.At that time，hunger was a serious problem in many parts of the countryside.Dr Yuan searched for a way to get more rice with the same size of the fields.In 1974，he became an agricultural pioneer in the world to grow rice that has high production and that is called super hybrid rice.In the 1980s，he went around the world and gave advice about growing rice to farmers in other countries.In 2004，he won the World Food Prize for his work.
Dr Yuan was quite satisfied with his life.He would much rather keep time for his hobbies.He enjoyed playing the violin，swimming and reading.Spending money on himself meant very little to him，so he gave millions of yuan to help some researchers with their research in farming.
Long ago Dr Yuan had a dream about rice plants as tall as sorghum （高粱） .With his hard work，he grew the rice that could feed more people.President Xi Jinping praised him for his great contributions （贡献） to China's food safety and world corn development.

This 12﹣year﹣old Girl Built a Robot to Find Plastics in the Ocean
Anna Du was walking along the beach when she noticed plastics there．She reached down to pick them up， and quickly realized there were many more tiny pieces than she could deal with． It seemed impossible to clean them all up．
Du， 12 years old at the time， tried to solve the problem like any good scientist﹣first． by doing a little research． That's how she learned that 8 million tons of plastics end up in the oceans every year．
Then she got to work building something that could help solve the problem；a remote﹣operated vehicle（遥控潜水器）， or ROV． Her ROV can move through water and find plastics on the ocean floor．
The actually cool part of Du's ROV is the detection（探测） system． She uses a camera along with three different kinds of light to find the plastics． She also uses visible（可见的） light to find unnatural colors that might make the plastics stand out．
"She has a very good engineering sense to break down a problem like this and then go after it，" says engineer Casey Machado． "It sounds simple， but it's a level of thinking that's really amazing．"
Du started attending public events and workshops at a university when she was five years old， and so she picked up the engineering skills necessary to build her ROV． She says actually getting her ROV to move through water well was not easy． She failed many times， but she never gave up trying and testing．
When asked about future plans，she mentions wanting to address the effects of climate（气候）change．"I think there are a lot of problems that could be solved with new inventions，" says Du．
Du thanks her parents， who for years have taken her to student outreach activities， for supporting her interest in science， technology， engineering and math （STEM）． She says she has been able to meet students and scientists there．
"I know I want to be an engineer because I like building things to help solve world problems，" says Du．"But I'm not sure what kind of engineer I want to be yet．"
（1）What did Anna Du notice while walking along the beach？
（2）How old was Du when she did a little research to solve the problem？
（3）What can Du's ROV do？
（4）Why does Du want to be an engineer in the future？
（5）What made Du succeed in building her ROV？
There are plenty of myths（神话） to explain how the world came to have a moon to bring light to the night time． But now there is a plan for a man﹣made moon． It will give us much more light than the natural Moon．
China is preparing to put a man﹣made moon in the sky above Chengdu by the end of 2020．It will reflect sunlight back onto the Earth． If it succeeds， three more such objects will be sent out in 2022，according to Wu Chunfeng， a space scientist． Wu said it would be similar to how we get moonlight， but he predicted（预言） that the man﹣made moon would have eight times the brightness of the real one．
This is because the object will be about 500 kilometers above the Earth． That will make it much closer to us than the moon， which is over 380 ，000 kilometers away，Wu added．
If the plan works， the man﹣made moon will save a lot of power．Scientist predicted that Chengdu could save around 1.2 billion yuan in electricity every year if a new moon lit up 50 square kilometers of the city．And in 2022 ， four man﹣made moons can take turns reflecting sunlight as they will not always be in the best position relative to the Sun． Together， they can give light to an area of up to 6 ，400 square kilometers on the Earth for 24 hours．That means its brightness will be seen in most areas in China，so reducing the need for streetlights．

Zhong Nanshan（1936.10﹣﹣） He is one of the famous medical scientists in the 21st century．Dr．Zhong Nanshan was the first to tell the public that the virus could be transmitted from person to person． He is a good doctor in the countrymen's eyes and respected by all Chinese people． |
|
Li Lanjuan （1947.09﹣﹣） When COVID﹣19 broke out， she suggested that Wuhan should be locked down immediately to prevent the spread of the disease． She headed for Wuhan and took an active part in the battle． Now， she still receives patients every day． |
|
Wang Yong （1985.12﹣﹣） As a delivery（快递）driver，he volunteered to support the medical staff in Wuhan during the epidemic（疫情）．He tried his best to keep life going for the doctors and nurses．Time magazine has put on its cover，presenting the courage and hard work of common people． |
|
Li Wenliang （1985.10﹣2020.02） He is the first doctor to warn people how dangerous the virus could be at the end of last December，so people call him the "whistle ﹣blower（吹哨人）．Because of COVID﹣19， he lost his life on February 7th， 2020． People across the country were sad to hear about his death． |

Some primary schoolchildren have been raised in homes with more green space around． They are likely to come with larger volumes of white and grey matter in certain areas of the brain． These differences are associated（关联） with beneficial effects on cognitive function （认知功能）． This is the main conclusion of a study led by the Barcelona Institute for Global Health．
The study was performed among 253 schoolchildren in Spain．Lifelong exposure（接触） to green space in the living places was recorded﹣using the information on the children's addresses from birth up through to the time of the study． Brain structure was studied using 3D magnetic resonance imaging （MRI）． Working memory and inattentiveness（注意力不集中）were graded with computers．
"This is the first study that shows the association between long﹣term exposure to green space and brain structure．" Says Dr． Payam Dadvand， the leading researcher of the study． "Our findings suggest that exposure to green space early in life could result in beneficial structural changes in the brain．"
The findings show that long﹣term exposure to greenness is positively associated with white and grey matter volumes in several parts of the brain． Some of them are related to higher scores on cognitive tests． Moreover， larger volumes of white and grey matter in those parts might lead to better working memory and less inattentiveness．
Exposure to nature has been thought to be necessary for brain development in children． Another study of 2，593 children shows that children in school with more green space have a greater increase in working memory and a greater decrease in inattentiveness．
Humans are believed to be tied to nature． Playing in greener areas offers children opportunities to search and learn． Accordingly， green space is thought to promptimportant exercises in discovery， creativity and risk taking． These exercises in turn positively influence brain development．
Dr． Dadvand's study suggests how such structural changes could bring about the beneficial effects of green spaces on cognitive development． It also adds to the proof that suggests the lasting effects of early life exposure to greenness on our health and the benefits of increasing greenness in cities．
Further studies are needed to prove the findings in other populations， settings and climates． And researchers need to examine differences according to the nature and quality of green space．
（1）The second paragraph is mainly about ．
A． how the study was performed
B． what was recorded in the study

Texting while driving is against the law in 47 states． But what about texting while walking？ A 2018 study reported that more than 2， 500 people in the US ended up in hospitals resulting from using a mobile device（设备） while walking．
Hawaii passed a law making it illegal（违法的） to text or look down at a mobile device while crossing the street． It is the first state with a law like this． Do people think more places should accept such a law？ The LA Times did a survey． Here are some replies they received．
Rena Jose， 2， New York Which is more important， texting or safety？ If you are looking at your phone while walking， you might not see a car come or traffic lights turn red． It can be very dangerous． For example， in Japan， one person fell into a lake and another got her leg stuck in a hole， because both had their mind on their phone． We should make texting while crossing the street illegal in more cities． |
Andy Selvam， 55， California People do many things that cause injury to themselves but are not illegal， such as climbing mountains， driving cars， swimming and so on． People might get hurt from texting and walking if they're not paying attention． But I still think they should have a choice． |
Bob Madigan， 45， Oregon As humans， we can make our own decisions． I'm not saying it's safe， but we don't need the government to babysit us． If we want to learn to make smart decisions， the government needs to stop telling us what to do． After all， this is a free country． |
Andrew Black， 34， Alaska This law is a good idea﹣compare this protection with seat belts． If this law is passed all over US， people will be worried． But is there really a way to please everyone？ This would not be for fun． It would be safe and good for all Americans． |

"Made in China" is having its moment now﹣and it's a fashionable one．
The story of Chinese fashion began in 2011 when Feiyue and Huili， both Chinese sports shoe brands（品牌）， suddenly got international attention． Their products were seen all over the world． Chinese sportswear brand Li Ning was at the New York Fashion Week in September， 2018． They showed their new designs﹣sweaters and jackets with Chinese characters．
Shaun Rein， managing director of China Market Research Group， said that the latest Chinese brands no longer catch customers' eye by low price． He told CNN， " They are sure that they can go head to head with foreign brands．
Maybe it is because China's young people are now more confident about their own culture． They don't show immediate interest in western culture any more．
"Today's young people in China are crazy about Chinese cultural elements（元素）．" Jin Qu， the manager of a clothing shopping website， said at a cultural festival in 2018． They like these elements printed on their clothes， even the brand picture of Laoganma in China， which was once seen as outside of fashion． But now young people are proud of these Chinese symbols．
"In fact， many stars in the West are now interested in Chinese cultural elements in fashion． Rihanna， a US singer， for example， wore a Chinese red dress to the 2015 Met Gala in New York． The dress was designed and made by Chinese designer Guo Pei．

On March 10，2019，eight﹣year﹣old Tani won the New York Chess Championship （纽约象棋冠军赛）of his age group． But the boy， who was homeless at the time， began learning the game less than a year ago．
Tani and his family arrived in New York City from Africa in 2017． A church helped him enter the primary school， P．S.116． Here the gifted boy was first introduced to chess by a part﹣time teacher Makofsky， owner of a chess club． Interested in the game， the seven﹣year﹣old asked his mother to allow him to join the club． Not able to afford the chess classes， she emailed Makofsky． To her surprise and joy， Makofsky agreed that Tani could learn it for free．
Though the chess club helps， it's largely believed that Tani's success lies in his hard work． The boy practices the game for many hours a day on the floor with his board． Every Saturday， Tani goes to a free 3﹣hour class to improve his game skills．
Not surprisingly，Tani's story， first reported by The New York Times， has brought him great support from the American public． Soon after the young boy won the New York Championship， Makofsky began a GoFundMe activity for Tani and his family so that he could continue his chess journey． It raised ＄200，000 in just ten days， far more than they expected． And the money keeps coming． But the family donates （捐赠）most of the money to the church and to those poor families!
Tani has also received offers from three famous private schools in New York． However， the family have politely refused all of them and chosen to continue Tani's education at P．S.116．
The young boy's story also caught the eye of Bill Clinton，the 42nd US President． "Tani，you're an example of a winning spirit ﹣ in chess and in life． I'd love to meet you，" he said on his Facebook．
While excited about his new life，Tani is ready to meet great challenges （挑战）．He is busy preparing for the 2019 National Primary Championships． Winning the competition will bring the chess player closer to his dream of becoming the world's youngest chess grandmaster （大师）． The record has been kept for 17 years by the Russian chess player Karjakin， who won the title at the age of 12．

A 3﹣year﹣old boy who was lost in the woods for two days is now safe at home with his family．But Casey Hathaway told his rescuers（救援者） that he was not alone in the rainy，freezing cold woods． He said he was with a friend﹣﹣a bear．
The child went missing on January 22 while playing with friends near his grandmother's house in North Carolina． When the other children returned but Casey did not， the family searched the area for almost an hour before calling the police．
Police formed a search team to look for the young boy in the nearby woods．But two days went by and ﹣﹣ no Casey．
Then on January 24，someone called the police saying he heard a child crying in the woods．Police followed up on the information and found Casey at about 9：30 that night． He was in good health．
Casey told the rescuers he had hung out with a black bear for two days， a bear he called his "friend"．
The police officer Chip Hughes spoke with reporters from several news agencies． He said Casey did not say how he could survive in the woods for two days in the cold， rainy weather．"However，the police officer said， "he did say he had a friend in the woods that was a bear with him．"
Hundreds of people helped in the search and rescue efforts， including some 600 volunteers，police and members of the army． Doctors at the medical center gave Casey some examination． He was then sent to his family on January 25．
