This is such a heart﹣warming piece of news in the cold winter． Some days ago， the temperature was only ﹣6℃ in Kaifeng， Henan． Someone ordered 50 cups of warm porridge（粥） through Meituan App and noted " Please give the porridge to those sanitation（环卫） workers who are clearing snow on the road nearby and those delivery（递送） men who are delivering food． "When the porridge shop owner received the order， he was moved by the note and provided 60 cups．
The story didn′t end here． As soon as the food delivery man got the big order，he shared it with his workmates so that they could also get paid． Finally， Meituan returned the money to the porridge buyer， Mr． Zhang and gave him a reward of ¥500． Although he had to raise his newly﹣ born baby and pay for his
house every month， Mr． Zhang said he would surely continue delivering love．
The kind help also encouraged many other citizens in Kaifeng．This summer，volunteers are sending cool drinks everyday．
Similar stories have happened in many other places in China． Outdoor workers in different cities are able to enjoy free and caring help． Lots of "love posts"are providing "coolness"in hot summer and"warmth"in cold winter． Just as a citizen of Kaifeng said，"I feel deeply moved and warm in heart．"
In fact， we get love and give love every day． Love delivery makes our life better and more beautiful．

Lots of students know what a marathon （马拉松赛跑） is， but perhaps they don't know what a triathlon is． The triathlon is a sport that has three parts ﹣ swimming， bicycling and running． It is not an easy sport， but a man named Joe Salter is very good at it． A few months ago， he finished a special triathlon ﹣ he juggled （抛起接住） three balls all the time during the triathlon． That is to say， he kept on throwing and catching three balls while he was swimming， riding a bicycle and running．
31﹣year﹣old Joe is from Florida， the USA． He loves juggling and he started at the age of 8． Joe did well in juggling． Later， he got the idea to do a triathlon and juggle at the same time to make it more fun． Many juggling fans laughed at his idea and thought it was just a joke． But Joe didn't give up and he kept practising it． Because of his hard work， he made it at last．
Talking about his triathlon， Joe said swimming was the hardest part． "lt was difficult and complex（复杂的），" he said． "I basically only used my legs， so it took quite a lot of work． Also， swimming in open water made it a little harder． It was not like in a pool．"

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．

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.

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.
Answer the questions according to the passage. （必须使用完整语句作答）

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？
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．
