When you look up into the night sky， you can see the moon． But do you know that you're only seeing one side of the moon？ The other side， also known as the far side of the moon， has long been a secret to us． But now， we have a chance to see what's on the far side．
On January 3rd，China's Chang'e 4 probe（探测器） landed on the far side of the moon． It is the first probe in history to land there．
Chang'e 4 probe has already done a lot of things on the moon． One of its jobs is to grow plants． Chang'e 4 probe took six living things to the moon． Such as cotton， potatoes and fruit flies（果蝇）． The cotton has already started growing． This is the first time humans have grown plants on the moon．
Chang'e 4 probe also took a lot of pictures of the moon's far side． With these pictures， scientists will learn more about the moon．
（1）According to the passage， we can see both sides of the moon． （判断对错）
（2）Growing plants on the moon is Chang'e 4 probe's only task． （判断对错）
（3）Chang'e 4 probe is the first probe to land on the far side of the moon． （判断对错）
（4）Seven living things were brought to the moon by Chang'e 4 probe． （判断对错）
（5）The cotton has already begun growing on the moon． （判断对错）
Every 14 days, another language dies． There are many reasons for this． Some people think more common languages have more economic（经济的） power． Because of this, young people choose to learn a common language as they think it is more useful． Another reason is that some languages aren't written down． Guujaaw is a leader of the Haida Nation, whose people have lived on the Queen Charlotte Islands, Canada, for more than 10, 000 years． Their language is endangered． Traditionally, it wasn't written down, and, as a result, some people are worried that it will die one day． Guujaaw replies to this," We talk to each other,listen, visit, and believe in the spoken word． Expressing yourself without writing is natural．" However, if Guujaaw's language and others like it are going to stay alive, writing may have to become part of their lives．
When a language dies, a lot of knowledge dies with it． To begin with, language is a huge part of the culture of the people who speak it． Language allows speakers to say certain things： words that describe a cultural idea may not translate exactly into another language． Furthermore, many endangered languages have rich spoken cultures． Stories, songs and histories are passed on from older people to younger generations （一代）． Elizabeth Lindsey, an expert in languages , emphasizes（强调）this．" When an elder dies, a library is burned," she says．
Also, language death affects our knowledge about nature． Local people often have a deep understanding of plants, animals, and the relationship between them． David Harrison, a researcher on endangered languages, reflects,"80% of plant and animal species（物种） have been undiscovered by science．But that doesn't mean they're unknown to humans．"
Many languages are endangered． However, it's not too late． Children often grow up speaking two languages．"No one…becomes richer by giving up.. one language to learn another, "Harrison said． If children feel both languages are important, they will use both．So, it is necessary that children realize how useful their local language is．
（1）How many reasons are mentioned for endangered languages in Paragraph 1？

Since May 8， Boston Dynamics， doglike robot， Spot， has been in use at BishanAng Mo Kio Park in Singapore to help encourage social distancing during the COVID19 pandemic （新冠肺炎疫情） according to a report in the South China Morning Post．
Singpore’s government is funding the experiment of the robotic dog， which will last for two weeks at the park during offpeak（非高峰的） hours．
"The robot isn’t enforcing （强制 ）． It’s just giving people information and encouraging them， "Boston Dynamics founder Marc Raibert told CNBC． "When Spot is patrolling（巡逻）the area， there’s a parks officer nearby who can do whatever enforcement he decides is suitable． "
Cameras fixed on Spot will scan the surroundings and help officers work out the number of visitors in the park， but they cannot read faces and won’t collect any personal information． It also carries a loudspeaker to broadcast a prerecorded message to remind visitors of the importance of social distancing．
Without enough manpower， Singapore is turning to robotics to reduce the manpower required for park patrols and remind people about the risks they may be putting themselves and others in．
The question， however， is whether their use of Spot will be a good tool or will or only attract more people to it instead．
If the twoweek experiment proves successful， the government will consider using Spot at the park during peak hours． Singapore will also do studies to see if it’s worth using other Spots in other parks． Already， Singapore engineers are trying to improve Spot， making it tell if people are together in a group or strangers passing on the grass．
No one knows if Spot will stay after the pandemic is gone， but one thing is for sure： the robot is the hardest working dog in the world．
（1）Why is Spot used at BishanAng Mo Kio Park？
A． To draw visitors， attention to it．

D． officers
（3）What can we learn from the last 3 paragraphs？
A． The experiment is still in progress．
B． The use of Spot proves to be a good tool．
C． Spot will stay after the pandemic is over．
D． Singapore will no longer need other Spot robots．
（4）According to the passage， which of the following is TRUE？
A． Spot scares people into keeping a distance in public．
B． Spot patrols the park for two weeks during peak hours．
C． Spot can tell people together in a group from strangers passing by．
D． The parks officer nearby decides on the enforcement instead of Spot．

Rice is one of the most commonly eaten basic foods around the world.Buying it and cooking it is a daily matter.Yet for many，its presence has been a matter of life and death.It is a main food because it is easy to grow，besides low cost and convenience.A poor community in the developing world may find it difficult to bring in foreign fruits or raise cattle for meat，but it can almost certainly use the land it has in order to grow plenty of rice.
This was the great achievement of Yuan Longping，who passed away on May 22 this year.A great Chinese scientist，Yuan successfully developed what is known as "hybrid rice" which can produce up a 30% higher output.Yuan Longping was born in the year 1930，a time when China was very different.It was a nation，without modern industry，depending on the rice which they grew.The first few decades （十年） of his life were met with major social events，and a rapidly growing population that made food supply not last all the time.This experience left its mark on Yuan Longping，which made him focus on （关注） farming science and work on his research of hybrid rice.
His achievement would see the rice supply in China increasing from 56.9 million tons in 1950 to 194.7 million tons by 2017.By 1991，20% of the world's rice output came from hybrid rice，even if only being planted in 10% of fields.
Always remember，human development begins first with the most basic and sample things，such as developing rice.We should be thankful for scientific thinkers like Yuan.

（2）What did Yuan develop successfully？
（3）When was Yuan Longping born？
（4）What made Yuan focus on farming science？
（5）How many tons was the rice supply in China by 2017？
On April 26， 2017， a big Chinese ship caught the eyes of the whole world． China's first homemade aircraft carrier（航空母舰）hit the water in Dalian， Liaoning．
The new big ship is China's second aircraft carrier． It was designed in China and built in China， too． It is about 315meters long and 75meters wide． That is a bit larger than three soccer fields．
An aircraft carrier is like an airport on the sea． It can carry planes and troops to war． Planes fly from and land back on it， and soldiers work and live on it， too． But building an aircraft carrier is very hard and expensive． It costs a lot of money and needs a large amount of steel and other special materials． For example， a basic aircraft carrier is made of 60，000tons of steel． It also uses complex（综合的） technologies， including radar， electrics， mechanics and weapons． Finally， it takes years to build．
Today， not many countries own an aircraft carrier or have the ability to build one． China has become the seventh country in the world that can build an aircraft carrier by itself， after the USA， Russia， England， France， Italy and Spain．

Antarctica （南极洲） is at the southern end of the Earth． It is the coldest， driest and windiest place on our planet． What would it be like to live and work there？
On Oct 15， 50 Chinese researchers took a ship named Xuelong 2 from Shenzhen to Antarctica． Xuelong 2 is the first icebreaker （破冰船） made in China． It took two years to build Xuelong 2． It is reported that Xuelong 2 is one of the world's best research icebreakers．
Chinese researchers have been to Antarctica 35 times． Because of its unusual environment， researchers from around the world have been going there to do study （研究） for many years． Some studies can only be done in Antarctica． For example， there is little air pollution there． This makes it easier for scientists to study the weather， atmosphere （大气） and stars．
The study of Antarctica's geology （地质） is also important． Rocks in Antarctica can tell us what the weather was like long time ago， and help us understand how the Earth has changed over time． There are also many wild animals， such as penguins （企鹅），seals （海豹） and birds． Scientists can learn how animals live in cold places by studying them．
Xie Zhouqing is a professor at the University of Science and Technology of China． He was part of China's 15th research trip to Antarctica． He said， "Life in Antarctica is not easy．It is tiring and sometimes dangerous， but it is still quite fun．" He also said，"I studied how penguins walk， what they eat， and why they move from one place to another． I was excited to see the cute animals playing around． I hope my studies can help protect them．"

Many kids help their parents with chores， such as doing the dishes， cleaning the living room and taking out the rubbish． And some kids get money or other rewards（奖赏） such as more computer time by doing chores．
But some people do not think that kids should get rewards by doing chores． Susie Walton．an expert， believes that by rewarding kids， parents are sending a message that work isn't important unless you can get something． "Running any kind of family is a team work，" Walton says． "A home is a living place for everyone in the family． It's important for kids to see that we all have responsibilities in the house．"
Other people believe that getting money or other rewards makes kids do chores happily and it also teaches them real world lessons about what we need to do to make money． There are also now apps（应用软件）． With the Chore﹣Monster app， kids can get points and online gifts by doing chores． Kids can change them into real life rewards either online or in the real world． "We hope kids can do more chores so they can get more rewards，" one man says．

Recently， the result of the national reading survey has been announced and it paints a brighter future for reading habits in the Internet times． Last year，21，270 men from 55 cities answered the survey． It showed that the Chinese people's reading rate increased slightly over the year before． Reading rate means the percentage of citizens regularly reading books， newspapers and digital （数字）reading materials．
The survey shows that the daily reading time and yearly reading number of paper books，printed newspapers and magazines have dropped， while digital reading has continuously increased．Every day Chinese people use different digital devices like mobile phones， personal computers or iPads for 100.41 minutes on average （平均），15.5 percent higher than the year before．
According to the survey， Chinese people's reading habits have changed because mobile phones provide more chances to get different kinds of reading materials on digital platforms． More than 50 percent of the Chinese people who were interviewed prefer digital reading， mostly on mobile phones．
Another interesting result is that an increasing number of people like to listen to audiobooks（有声读物）．More than 30 percent of the people who answered the survey listen to audiobooks，higher than the year before． It may have something to do with the way people go to and from work﹣many people in the countryside drive or take public transport for long hours， which leads to the greater need for audiobooks．
People's reading habits are changing with social changes． In my opinion， the relevant authorities （相关机构） should pay attention to it and shouldn't fall behind．

The 2019 Beijing International Horticultural Expo（北京世界园艺博览会）began in Yanqing，Beijing，on April 29． This is the second time that China hosts such an event since the 1999 Kunming International Horticultural Expo．
As a language of communication between human beings and nature， horticulture is the art of plants，the green culture and the sublimation（升华） of life． It can lead you into the world of plants and let you experience the beautiful moments brought by gardening．
More than 100 countries and international organizations have entered the international horticultural exhibition area， and 41 outdoor exhibition gardens have been built． Taking the Beijing Outdoor Exhibition Garden as an example， China takes "courtyard house" as the important landscape（景观）of Beijing Garden to①the harmonious coexistence （和谐共存） between people and nature．So the whole world can see a "big Beijing" from a "small courtyard"． The reporter has learned that 180 "Flower Shows" are held during the event and the Chinese national cultural stories are told by ten ecological cars， which are made of fresh plants．
In 2019，the Beijing International Horticultural Expo will sublimate the mix of cultures．With the theme of "Live Green， Live Better"， the expo opened to the public on Monday at the foot of the Great Wall in the capital's Yanqing District and will last②Oct.7．During that time， let's go on a green journey and meet at the foot of the Great Wall．

More Chinese universities are opening their libraries to the public，allowing people to enjoy reading during normal time and the vacations．
But for some students，including Wang Ling，21，in Sun Yat﹣sen University，this practice has caused headaches．"Members of the public come to our libraries more for sightseeing than reading，"said Wang．
"They sometimes even bring their kids along，and take photos as if it were a place of interest．"
Wang has found it hard to get a seat during busy times．Being short of space is a common problem for university libraries in China．
However，this is not the only reason why students dislike their libraries being open to members of the public．They fear that the quietness of the libraries will be influenced because of visitors' rude behavior．
Chen Jie，18，a student in Tongji University，is one who would be against opening to the public．"I have been to a public library before．People were chatting loudly or speaking on cell phone so you can hardly read，"Chen said．She notices teachers doing serious reading and feels their concentration（专注）has influenced her．"If too many strangers stay here，the whole library will be a noisy place and it's difficult for us to study quietly，"she said．
Will there be alternative（可替代的）ways to share those libraries？Some experts consider that university libraries can stop the public from entering certain areas．"We might keep magazines for academic research only for teachers and students，"said Zhu Lina，library director in Jinan University．
Working together with the community library is another solution（解决方法）．"It's possible that a member of the public can order a book in our library over the Internet，"Ge Jianxiong，the library director in Fudan University said．"We'll send it to a public libraries close to their home．"
