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.

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.
Chinese government has also taken other steps to protect students' eyesight in China.In May 2020，the National Health Commission urged schools to make sure that students have at least two hours of outdoor activity a day.

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. |

Breath Sample |
Number of Times the Dogs Sat Down |
Number of Times the Dogs Kept Standing |
Breath from lung cancer patients |
564 |

720 |
No lab test for cancer has given more correct results than this test.The results are so amazing that many experts question the dogs' smelling power.They wonder if there were other reasons why the dogs did so well.For example，they thought the way the dog trainers behaved could have influenced how the dogs acted.However，most experts agree that this study is important.The information could help scientists create a simple breath test for cancer in the future.Once again humans may be getting a helping paw or nose﹣from their best animal friends.
（1）What's the latest tool a dog might have in the fight against cancer？
A.Tooth.
B.Nose.
C.Ear.
（2）What happened first in the Pine Street Foundation test？
A.The dogs were trained.
B.The tubes were placed one yard apart.

（4）Look at the chart.How many times did the dogs keep standing when they smelled the breath from healthy persons？
A.Less than 10 times.
B.Almost 600 times.
C.About 700 times.
（5）Why do many experts question the dog's smelling power？
A.Because no lab test for cancer has given more correct results.

Most viruses can be found and killed by our immune system as soon as they enter our bodies.However，some viruses，for example，the coronavirus，are sneaky.They are difficult to recognize and find.These viruses can cause deadly diseases，like COVID﹣19.Human﹣to﹣human transmission can easily occur，and pandemic will therefore break out.Vaccination is by now a simple，safe and effective way to protect us from the diseases.
▲Vaccines are something that "looks" exactly the same as the viruses，mainly made from the viruses that are weakened or killed.They will not make us really ill.They only stimulate and activate our immune system to work，telling it something harmful is coming in.The immune system will know what the "viruses" look like，and send B cells（lymphocytes）or antibodies to find and kill them.Meanwhile，B cells will remember them for the next kill.A vaccine may also give us passive immunity by providing B cells taken from an animal or a human to play the same role.
Scientists have developed more than 180 vaccines to fight against COVID49.The technical approaches of these vaccines can be a little different，but their aims are the same.
Take the inactivated vaccine as an example.In an inactivated vaccine，the coronaviruses are already killed or made into the ones unable to produce more new viruses.When the immune system "sees" them，it will try to kill them.The question is：without enough these viruses• how can B cells remember them？That's why we need to take the vaccine more than one time.Though this vaccine is safe，it might not be as effective as it is expected to be.
The live﹣attenuated vaccine is different.In this vaccine，the viruses are weakened，but they are alive.They can produce enough new viruses to train the immune system to kill and remember them，so people only need to take the vaccine once.The live﹣attenuated vaccine is considered the most effective，but there is a worry：what might happen once these viruses wake up？
Therefore，although vaccination is by now one of the best ways to protect us from COVID﹣19，it can be better.
（1）The coronavirus can .
| A． |
not be killed |
| B． |
not be found |
| C． |
cause deaths |

（3）Compared to the inactivated vaccine，the live﹣attenuated vaccine .
| A． |
needs taking more than once |
| B． |
is equally safe |
| C． |
contains viruses that are killed |
| D． |
is more effective |
（4）What can we learn from the passage？
| A． |
Vaccination is good enough to treat COVID﹣19. |
| B． |
The immune system can be more effective with vaccines. |
| C． |
The viruses in inactivated vaccines can make new viruses. |

In 1987 a small company named Huawei was started in Shenzhen.After more than 30 years of development，the company has now beaten Apple and become the world's second largest maker of smartphones.It has also become the world's supplier （供应者） of 5 G.In China and even in the world，Huawei is a wonder.Although it started producing mobile phones not many years ago，it has become one of the most famous phone companies.
But recently，Huawei faces some difficulties.The US government made a law to stop its sales in America.American officials said Huawei gave information that it collected to the Chinese government.At the same time，the US government planned to stop selling parts and services to Huawei.They believed that Huawei's business would be hurt this way.
"We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information，" Ren Zhengfei，Huawei's president said. "The law would have little effect on our company.Huawei has enough ability to deal with the problems，" Ren added.
In an interview several years ago，Ren Zhengfei said， "I started Huawei with only £4000 at the beginning，but now it has become a 100 billion company.The experience was not as romantic as you imagine."
Facing the law of the US，Huawei is growing.Huawei's smartphone sales around the world rose 50 percent compared with a year earlier in the first three months of 2019.At the same time，sales from both Samsung and Apple fell.So far Huawei has grown into the world's largest telecommunication equipment supplier （供应商），selling in 170 countries.It may beat Samsung as the largest smartphone maker in the near future.

Many people know that rubbish is a big problem on planet Earth． What many people don't know is that junk（垃圾）has become a problem in outer space too．
According to BBC News， there are more than 22， 000 pieces of space junk floating around the earth． And these are just the things that we can see from the surface of the earth by telescopes （望远镜）． There are also millions of smaller pieces of junk that we can't see．
Objects， like bits of old space rockets or satellites， move around the planet at very high speeds，so fast that even a very small piece can break important satellites or become dangerous to astronauts． If the tiniest piece of junk crashed into a spaceship， it could damage the vehicle．
To make things worse， when two objects in space crash， they break into many smaller pieces． For example， when a U．S． satellite hit an old Russian rocket in 2009， it broke into more than 2，000 pieces， increasing the amount of space junk．
To reduce additional space junk， countries have agreed that all new space tools can only stay in space for 25 years at most． Each tool must be built to fall safely into the earth's atmosphere after that time． In the upper parts of the atmosphere， it will burn up．
Many scientists also suggesting different ways to clean up space junk． In England scientists are testing a metal net that can be fired into space junk． The net catches the junk and then pulls it into the earth's atmosphere to burn up． The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed．
The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers，" says Marco Castronuovo， an Italian space Researcher．
"The time to act is now． The longer we leave the problem， the bigger it will become，" he says．

It seems that food deliverymen （送货员） are always rushing in haste.We can always see them running every minute，and they seem to have lots of things to do the next minute.They wear blue，red or yellow helmets （头盔） and many of them don't follow traffic rules.They drive on the wrong side of the road and run red lights.They use mobile phones when they are driving.
However，not everything goes well with food deliverymen.In the first half of 2017，food deliverymen had 76 traffic accidents in Shanghai.That means every two and a half days，a food deliveryman will die or get hurt on the road.
What makes deliverymen take such risks？The strict rules of the food delivery companies and the worried customers may be the answer.Many companies will fine （罚款） a deliveryman up to 2，000 yuan if he can't deliver the food on time，reported China Daily.Fines also go to those who get bad reviews from customers.
To solve the problem，food delivery service companies need to do some changes.Some cities are also taking action.Shanghai has asked companies to train their deliverymen on traffic rules and safety.Now in Shenzhen，if a deliveryman breaks traffic rules more than twice，then he can't do the job for a whole year.

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.
