Ever wondered why your virtual（虚拟的）home helper doesn't understand your questions？Or why your navigation app took you on the side street instead of the highway？In a study published April 21st in the journal Science，Italian researchers，Arianna Pipitone and Antonio Chella，designed a robot that "thinks out loud".
To explore how inner speech might influence a robot's actions，the researchers built a robot called Pepper that speaks to itself.It has the ability to reason and think.They then asked people to set the dinner table with Pepper according to etiquette（礼仪）rules.In one experiment，the user asked Pepper to lay the napkin at the wrong place，going against the rules.Pepper started asking itself a series of self﹣directed questions and concluded that the user might be mistaken.To be sure，Pepper confirmed the user's order，which led to further inner speech.
"Ehm，this situation troubles me.I would never break the rules，but I can't make the user unhappy，so I'm doing what he wants，" Pepper said to itself，laying the napkin where it was required to be.Through Pepper's inner voice，the user can learn Pepper was facing a difficult situation and solved it by prioritizingthe user's order.
Comparing Pepper's actions with and without inner speech，Pipitone and Chella discovered the robot had a higher task﹣completion rate when having self﹣dialogue.
However，some people find the robot spends more time completing tasks when it talks to itself.The robot's inner speech is also limited to the knowledge that researchers gave it.Pepper's designers still say their work provides a framework（构架）to further explore how self﹣dialogue can help robots focus，plan，and learn. "In some ways，we are creating a generational（世代的）robot that likes to chat.From navigation apps and the camera on your phone to medical robots in the operation rooms，machines and computers alike can take advantage of this chatty feature，" says Chella.

Named after the "quest for heavenly truth"，Tianwen 1，China's first Mars probe（探测器），has given us impressive pictures of the red planet.The first high﹣resolution（高分辨率的）pictures of Mars taken by Tianwen 1 were made public by the China National Space Administration（CNSA）on March 4.
"These are the first close﹣up pictures of Mars' surface taken by China， " said Bao Weimin，a scientist of the Chinese Academy of Sciences.
The pictures were taken at different distances from Mars.The two black﹣and﹣white pictures were taken by the high﹣resolution camera on Tianwen 1 when the probe was about 330﹣350 kilometers above the Martian surface.As for the color picture，it was taken by Tianwen 1's medium﹣resolution（中分辨率的）camera when the probe was about 5，000 kilometers above the red planet. Itshows Mars' North Pole.
The high﹣resolution camera can take both color and panchromatic（全色的）pictures.Panchromatic pictures，which are black and white，are the clearest，having the largest amount of data for scientific study，said Liu Tongjie.The medium﹣resolution camera，can only produce lesser clear pictures.Scientists put the panchromatic and color pictures together to form a clear and beautiful color picture，Liu added.
Tianwen 1，the country's first independent Mars task，was sent up on July 23，kicking off the nation's planetary exploration program.The probe entered its preset orbit above Mars on Feb 24 and is looking for a landing site on the planet's largest plain.The probe is expected to land on the red planet sometime between May and June.

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
C． how long the study lasted
D． who took part in the study
（2）The word "prompt" in paragraph 6 probably means " "．
A． control
B． encourage
C． balance
D． change
（3）What can we learn from the passage？
A． Working memory influences white and grey matter in the brain．
B． Dr． Dadvand stressed the importance of changing the environment．
C． Studies proved the influence of greenness on populations outs of Spain．
D． Living in greener neighborhoods benefits children in brain development．
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.

With her eyes feeling increasingly tired and her vision blurry（视力模糊的），l6﹣year﹣old Tian Ting went to the hospital with her parents in January.She was shocked when she found out that her eyesight dropped from 5.0 to 4.6 in only a term. "A few of my friends have had the same experience lately，" Tian said.
In fact，poor eyesight among Chinese primary and high school students rose from 59.2 percent to 70.6 percent in the first six months of 2020，according to the Ministry of Education.
To protect students' eyesight，the Chinese government has worked out new requirements （要求） for school supplies （供应品） and equipments that will take effect （生效） on March 1，2022.For example，according to the requirements，the size of text in students' textbooks should be no smaller than nine﹣point.Teachers should also try not to use projectors （投影仪） or other multimedia equipments （多媒体设备） that are too bright，Beijing Daily reported.There are also requirements for desks and classroom lights.For example，these lights should give off （散发） as little blue light as possible.
Blue light is bad for our eyes，as it can kill the photoreceptor cells （光感器细胞） we need for vision，according to Harvard Medical School.Many of the electronic devices we use every day，like our phones and computer screens，give off blue light.

Dogs might have the latest tools in the fight against cancer （癌症）：their noses!Researchers at California's Pine Street Foundation （PSF） say they have trained five dogs to smell cancer on a prison's breath.This could be exciting news.
A dog's sense of smell may be 10，000 to 100，000 times stronger than ours.But can dogs really smell illness？PSF researcher Michael McCulloch says yes. "We were very surprised by how exact they were，" he said. "They were telling who had cancer，and they were also saying who didn't."
McCulloch and his team asked four healthy people and one with cancer to blow into plastic tubes （塑料管）.Special materials in the tubes kept the things of each breath.The tubes were then placed one yard apart.Finally the dogs were allowed to smell the tubes.Each dog had been trained for three weeks to sit when it smelled cancer.Ninety﹣nine percent of the time，the dog sat next to the tubes blown into by patients with lung cancer.The dogs were right 88 percent of the time about breast cancer.
Dogs in the Pine Street Foundation test were trained to sit when they smelled cancer.How well did they perform？Take a look at this chart to find out. |

China has named the nation's first Mars rover（火星车）Zhu Rong.For all of us，Zhu Rong is a well﹣suited name.
In an ancient Chinese story，Zhu Rong had the face of a man and the body of an animal.He rode on two dragons.When he had a big fight with Gong Gong，the god of water，Zhu Rong won.But after the fight，the human world came into complete darkness.Then he brought fire from heaven（天国）to the world.
"Zhu Rong is regarded as the earliest god of fire in traditional Chinese culture，" a space official said. "The first Mars rover was named Zhu Rong.The name symbolizes（象征）light and hope for space exploration（探索）in our country，and means to guide humans to continue exploration."
After leaving the earth last summer，Zhu Rong circled Mars for several months and landed on it in May.In recent years，our country has sent up the world's first quantum satellite（量子卫星），and Chang'e﹣4 has made a soft landing on the moon.We have made great progress in space technology and will soon start building our own space station.

The first emperor of China，Qin Shihuang，completed a huge number of projects during his rule.Between 221 and 210 B.C.，he started the building of the Great Wall.The emperor also ordered the building of a huge army of life﹣sized terracotta soldiers（士兵）.These，he hoped，would protect his tomb after his death.
Lost in Time
The soldiers in Xi'an's terracotta museum are today light brown，but they weren't always.They began as an army of red，blue，yellow，green，white，and purple.Sadly，most of the colors did not last to the present day.After being exposed（暴露）to air during digging，the coating under the paint began to fall off.The paint disappeared in less time than it takes to boil an egg，taking away with it important pieces of history.
New Technology
Now new technology is starting to show the army's true colors.Archeologists（考古学家）have recently discovered an area with more than a hundred soldiers.Many of these still have their painted features，including black hair，pink faces，and black or brown eyes.Chinese and German researchers have developed a chemical liquid（液体）to help save the soldiers' colors.After finding a soldier or another art piece，archeologists put the liquid on it. They then cover it in plastic.
Back to Life
Archeologists are also finding colors in the dirt around the soldiers.It's important not to do anything with the dirt，so the colors won't be lost. "We are treating the dirt as an art piece， "says Rong Bo，the museum's leading archeologist.The next challenge，says Rong Bo，is to find a way to use the colors onto the army﹣again.Once that happens，artists can bring Emperor Qin's army back to its full，bright colors.

D.Artists should be able to paint the soldiers in colors they want.
Have you ever imagined the life in space？The following will show you the astronauts' daily life.
• Eating in space
If you go camping for more than a week with some friends，you will make sure you have plenty of foods and keep them properly.At the end of your camping trip，you would deal with your rubbish properly before the ride home.
Astronauts almost do the same thing when they go to space.Preparation changes with the food type.Some foods can be eaten in their natural forms，such as chocolate cakes and fruits.Other foods require adding water，such as cheese.Of course，an oven is provided at the space station to heat the food.But there are no fridges，so space food must be kept properly.
• Sleeping in space
After a long day at work，nothing is better than a good night's sleep!Just like on the earth，in space astronauts go to bed at a certain time，then get up and prepare for work again.When going to sleep，they have to attachthemselves，so they don't float （漂浮） around or hit their bodies against something.They usually use sleeping bags located in small crew cabins （乘员舱）.Each crew cabin is just big enough for one person.Generally，astronauts have an eight﹣hour sleep each day when they finish their task.
• Doing sports in space
Exercise is an important part of every astronaut's daily life to prevent muscle loss （肌肉萎缩）.Usually，astronauts exercise two hours every day.Lifting 200 pounds on the earth may be a lot of work.But lifting that same object in space would be much easier.That means the things for exercise need to be specially designed，so astronauts can receive the exercise needed.
Living in space is not just all work and no play.Astronauts have fun，too.They like to look out the window and play with their food.Fun plays an important role in the quality of their life.
