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.

I think there are several reasons that suggest developing robots is a waste of money．
In San Diego recently ＄ 325，000 was spent on inventing a robotic squirrel to do some scientific experiments． The research proved that squirrels are able to scare away snakes by wagging （摇动） their tails． Do you need a robotic squirrel to work this out？
What about AIBO，a robotic pet，developed in Japan？ In Japanese aibou means "buddy"． These pets have been developed at huge cost mainly to provide entertainment．They've been used in movies and music videos． Universities have used them for educational purposes．However， in 2006 the company stopped producing these robotic pets in order to save money． Was it worth a lot of money？
Then there's NAO， a robot which has been developed by a French company．Its main purpose is to make life easier for humans． It speaks 19 languages and has its own personality．It can tell children a story， help in the classroom or the home， or act as a companion to those people who need someone to be with．A fully developed one costs ﹩16，000． Is that value for money？ Who can afford it anyway？
There may be good reasons why it is worth developing robots， but so far I haven't thought of any．
（1）What does the underlined word "companion" in Paragraph 4 mean in Chinese？
A．公司
B．机构
C．对手
D．伙伴
（2）What is the true fact about the robots mentioned？
A． The robotic squirrel is needed by every scientist to do some research．
B． AIBO wasn't made any more because it only provided entertainment．
C． A fully developed NAO may tell kids stories in different languages．
D． All the three types of robots used to be produced at a very low cost．
（3）What does the writer think of developing robots？
A． It can help bring people a lot of fun．

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．

Influenza， or flu（流感）， is a type of virus． It spreads from one person to another quickly． When someone who has the flu coughs or sneezes， little droplets from their lungs （肺） spread out into the air．Anyone nearby can get sick． Even a person who touches something with the virus and then touches his or her mouth， eyes， or nose， can become infected（感染）．
The outbreak of the 1918 influenza infected about 500 million people worldwide． It killed from 20 million to 50 million people． It was first seen in Europe， the United States， and parts of Asia．It then spread quickly around the world． Many people who became sick were young， healthy adults．At the time， no treatments worked in the prevention of the spread of the killer flu． People were ordered to wear masks． Schools， theaters and other public places were closed．
When the first wave（波＞in the spring of 1918 hit， it didn't seem serious． People who were infected felt the usual flu symptoms（症状）， which are chills， fevers， and feeling tired． Those who got sick generally got better after several days． Not many died． However， a second， highly contagious（传染的）wave of influenza appeared in the fall of that same year． Victims died shortly after they were infected ﹣ within hours or days． Their skin turned blue and their lungs were filled with liquid（液体），making it very difficult to breathe．
By the summer of 1919， the flu pandemic（大流行病） came to an end． Sick people had either got well or died． Almost 90 years later， in 2008， researchers announced they'd discovered why the 1918 flu was so deadly． The flu virus inflamed （使…恶化）the lungs， causing them to fill with liquid．

Earlier this year， China achieved a new milestone （里程碑） in space research． On January 3， 2019， Chang'e﹣4 became the first lunar probe （月球探测器） in history to successfully land on the far side of the moon．
The Earth's gravity （重力） slows the moon's rotation （自转）， matching it to the speed of its orbit （公转）． Therefore， the far side of the moon is almost "dark" and has never been seen． It's this sense of the unknown that makes the far side of the moon such an interesting place for scientific and space research． Being blown by solar （太阳的） winds， the far side may have the special minerals （矿物质 ）． For this reason， Chang'e﹣4 will study the effect of solar winds on the lunar surface and any mineral found by the spacecraft． Chang'e﹣4 is also carrying flower seeds， potatoes and silkworm eggs to see whether life is possible on the moon． If it is， then the moon will become a possible choice for space travel in the future．
However， research of the "dark" side isn't easy． As the far side is blocked（阻断） off from us， radio noise coming off Earth is also blocked． This is why China's relay satellite （中继卫星） Queqiao was sent up in May， 2018． Thanks to Queqiao， the communication problem between Earth and Chang'e﹣4 has been well solved．
Power supply （电源供应） is also a challenge to the task． Chang'e﹣4 gets energy from the sun through its solar panels． As we know， a lunar day has the length （长度） of 28 Earth days． After Chang'e﹣4 was sent up on December 8， 2018， it took the probe over 20 days to orbit the moon to be in a position to be able to land in moon daylight and use its solar panels．
Luckily， everything goes well， Chang'e﹣4 has worked on the "dark" side for over 5 months． It has sent back many photos of the far side of the moon and has been used to carry out some scientific experiments．
The New York Times used the word " groundbreaking" to praise the task and wrote that "it will offer help to the history and development of the moon"．
（1）When was Chang'e﹣4 sent up？
A． In May， 2018．
B． On December 8， 2018．
C． On January 3， 2019．
D． The passage doesn't tell us．
（2）The main tasks of Chang'e﹣4 don't include ．
A． studying if life is possible on the moon
B． studying the effect of solar winds on the lunar surface
C． solving the communication problem between Earth and other probes
D． researching any mineral found by the spacecraft
（3）The meaning of the underlined word "groundbreaking" in the last paragraph is the closest to " "．
A． harmful
B． unpredictable
C． risky
D． pioneering
（4）According to the passage， which of the following statements is NOT true？

The population of the world continues to increase， but in some areas the population is falling．This is true in Europe and especially in Eastern Europe． In Russia， the population is going down by about 100 people EVERY HOUR! Russia's population could fall by ONE THIRD by the year 2050! And in Poland （波兰）the population is also going down because people are leaving to work in other countries．
One of the main reasons is a change of lifestyle． All over Europe people， especially educated women， have a different attitude （态度）to children than their parents．"I have one child and she is enough for me， "said Galina Tereschkova， a doctor from Moscow． "My husband and I both work full﹣time． We can't imagine having more than one child． "Many women decide to have children later in life or not to have children at all． "I don't want to have any children until I have worked for at least 10 years， "said 19﹣year﹣old student Hana Markova from Prague． Her opinion is typical of 18﹣24 year old women everywhere in Europe．
In Poland， the population is going down for a different reason． A lot of people，usually aged between 20 and 30， are leaving the country to work abroad． Poland joined the European Union in 2005 and since then more than half a million people have moved to Britain， Germany， Spain and Italy． Even so， the population of those four countries and many other countries in West Europe is also going down．
Many governments are now encouraging people to have larger families． In France，women now receive nearly 1，000 a month for a year if they have a third child．Austrian women receive 700 a month for three years when they have their first child．

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.

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.

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.

The Brightest Star in the Sky
Yuan Longping is one of the most famous scientists.He regards himself as a farmer because he does his research in the fields.In fact，his sunburnt face and arms and his slim，strong body are just like those of millions of farmers.Dr.Yuan Longping grows what is called super hybrid （杂交性的） rice.In 1974，he became the first agricultural （农业的） pioneer in the word to grow rice hat has a high output（产量）.This special rice makes it possible to produce one﹣third more of the crop in the same fields.Now more than 60% of the rice produced in China each year is from the hybrid rice strain （品种，种类）.He was born in Beijing in 1930.Since he graduated from Southwest Agricultural College in 1953，finding ways to grow more rice has been his life goal.He searched for a way to increase rice harvests without expanding （扩大，增加） the area of the fields.
In a recent research，these increased harvests mean that 22% of the world's people are fed from just 7% of the farmland in China.India，Vietnam and many other less developed countries have planted super hybrid rice to increase their rice harvests.
Unluckily，he died on May 22，2021.Though he was ill in bed，he still cared about his rice in the fields.He always said，"A man is just like a seed.Please be a good seed." Yuan works for the people not only in China but also around the world.He has become a hero and is remembered in everyone's heart forever.He is called "the brightest star in the sky" by his students.
