Heads Up!
In November，the US Soccer Federation，the biggest soccer organization in the US introduces new rules to make the sport safer for young players．This organization
announced that players on its teams who are 10 or younger are no longer allowed to head the ball．Players aged from 11 to 13 have limits on how often they can practice heading．The new rules are designed to prevent kids from getting concussions﹣injuries caused by a blow to the head that shakes the brain inside the skull（头骨）．Common symptoms（症状） include headaches and dizziness．
A DANGEROUS MOVE
Heading the ball can be one of the riskiest parts of soccer．Sometimes the force of hitting the ball with their heads gives players concussions．But more often，players receive concussions when they jump to head the ball and accidentally knock heads with other players or fall and hit their heads on the grass．
"More concussions happen during the act of heading than any other action in soccer，"explains Dr．Robert Cantu，an expert on brain injuries．

From tiny seeds（种子）， great discoveries grow． A mini﹣garden carried on China's Chang'e 4 moon lander recently became home to the first plant to grow on another world．
This is yet another success for Chang'e 4． On January 2， the probe（探测器）became the first lander to touch down on the far side of the moon． This is the unknown face of the moon that is always looking away from us， so we never see it from down here on the earth． Although it is often regarded as the dark side of the moon， the far side actually gets as much sunshine as the near side． For example， when all we can see is a silver of a new moon， the far side of the moon is in full sunlight．
Part of Chang'e 4's mission（使命）is to see how a moon base could be built for humans， including exploring（探索）whether humans could grow food and other plant products there． Chang'e 4 carried a mini﹣garden with air， water and soil with seeds planted in it． When plants shoot on the earth， their stems grow away from the gravity（the force that keeps your feet on the ground），and so they always shoot upwards．The moon's gravity is a sixth as strong as the earth's， so Chang'e 4's experiment was a test：would the earth plants know which way was up on the moon？ Four days after landing， a tiny cotton shoot showed that they do．
Night has now fallen on the far side of the moon； sunlight will not return until the start of February．As a result， the cotton shoots died． Besides the darkness， the plants can't stand the cold（it can drop to ﹣170C on the moon at night）． However， the experiment is a success， since it has proved that it is possible for plants to grow in space．

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.

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.

（2）Why was Pepper asked to lay the napkin at the wrong place？
| A． |
To see how much time Pepper spent laying the napkin. |
| B． |
To confirm how popular Pepper was among its users. |
| C． |
To test how many etiquette rules Pepper remembered. |
| D． |
To study how self﹣dialogue might influence Pepper's actions. |
（3）What does the underlined word "prioritizing" in Paragraph 3 mean？
| A． |
repeating. |
| B． |
dealing with…first. |
| C． |
going against. |
| D． |
complaining about. |
（4）What can we infer from the passage？

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.
