Chinese researchers have developed a robot designed to help doctors treat the new coronavirus (新冠病毒) and other highly contagious diseases.
The robot can perform some of the same medical examination tasks as doctors. For example, the device can perform ultrasounds, collect fluid samples from a person's mouth and listen to sounds made by a patient’s organs. Cameras record the robot’s activities, which are controlled remotely so doctors can avoid coming in close contact with infected patients. Doctors and other medical workers can operate the machine from a nearby room, or from much farther away.
The robot's main designer is Zheng Gangtie, an engineer and professor at China’s Tsinghua University in Beijing. “Doctors are all very brave,” Zheng said. “But this virus is just too contagious…We can use robots to perform the most dangerous tasks.” Zheng said a friend of his, the head of Beijing’s Tsinghua Changgung Hospital, told him that one of the biggest problems in dealing with COVID-19 was that health care workers treating patients were getting infected themselves. Zheng said he wanted to do something to help this situation. So the engineer gathered a team and went to work on the robotic device. Zheng said the team was able to convert two robotic arms. The devices use the same technology that is used for space equipment, including moon explorers. The new robot is almost completely automated, Zheng said. It can even disinfect itself after performing actions involving patient contact. However, Zheng said he had heard from some doctors that it would be better not to build such robots to be fully automatic. This is because many patients still desire a personal presence to help calm them during treatment.
The team currently has two robots and both have been tested by doctors at hospitals in Beijing. One machine was taken to Wuhan’s Union Hospital, where doctors were being trained to use it. The plan is to use the robot to help treat coronavirus patients, along with assistance from nurses and other hospital workers.
Zheng would like to build more of the robots, but said money from the university has run out. About $72,000 has been spent on each robot. He said he does not plan to commercialize the design, but hopes that a company can begin that process.
1.What can we learn from Paragraph 2?
A.The robot can record doctors’ activities.
B.The robot can carry out actions automatically.
C.The robot can assist doctors to examine patients.
D.The robot can collect samples of patients’ organs.
2.The underlined word “disinfect” in Paragraph 3 is the closest in meaning to
A.affect B.clean
C.update D.fix
3.What can we infer about the robot according to Zheng Gangtie?
A.It is very costly to make.
B.It is highly recognized by doctors.
C.It can be purchased in the market soon.
D.It can also be used in moon exploration.
4.What is the main purpose of the text?
A.To introduce a new type of medical robot.
B.To provide guidance on treating COVID-19.
C.To describe the current condition of COVID-19.
D.To promote the commercialization of a new robot.

The team of researchers from the University of Lincoln, UK, is designing and building an app to help farmers in hot climates identify and record the spread of locusts(蝗虫) on their land.
By recognizing locusts through the smartphone’s camera, the app will be able to identify the stage of the insect's growth and record its location. This information can then be utilized so that the farmers can use pesticides(杀虫剂) more accurately in the early stages of their life time, greatly reducing the amount of crop damage.
This approach could also reduce remaining pesticide levels, leading to increased food safety while maintaining food security and protecting nearby water systems.
“Each year, approximately 18 million hectares of land are damaged by locusts, influencing hugely farmers and their productivity, explains Dr. Bashir Al-Diri from the School of Computer Science at the University of Lincoln.” Their monitoring techniques currently rely on field surveys by people through digging insect eggs, but this information only helps farmers to make mid and long-term forecasting decisions and can delay effective management measures. By digitally recording the exact number, age and location of locusts, we hope this new app will put more knowledge and more power into the hands of the farmers.
Dr. Al-Diri and his team of computer scientists work with the Lincoln Institute for Agri-food Technology at the University of Lincoln, aiming to support and improve productivity, efficiency and farming through research, education and new technology.
With advanced technology, the developers hope that the app will also be used for a wide range in the future to capture and document information about the natural world. For example, it could easily be adapted to help individuals identify plant diseases or to digitally capture the number and type of birds and wildlife in specific locations as part of national and international surveys.
1.What do we know about the app mentioned in the passage?
A.It has helped farmers record the spread of locusts.
B.It will be of great use for farmers in hot climates.
C.It may cost the farmers more than they expect.
D.It will remind farmers of what the locusts look like.
2.Which can replace the underlined word "utilized” in the passage?
A.Accessed. B.Controlled.
C.Arranged. D.Progressed.
3.What can we know according to Dr. Bashir Al-Diri?
A.Farmers don't know how to deal with locusts.
B.Their techniques can be used to dig insect eggs.
C.Farmers suffer greatly because of locusts.
D.Some steps must be taken before using the app.
4.What is the purpose of Al-Diri and his team?
A.To check if the app is useful in killing locusts.
B.To educate farmers on how to protect themselves.
C.To assist in raising agricultural production level.
D.To direct farmers to change their farming methods.

If you want to help children develop language and speech skills, UCLA researchers say, listening to what they have to say is just as important as talking to them.
The effect of a conversation between a child and an adult is about six times as great as the effect of adult speech input(输入)alone, the researchers found. “Adults speaking to children helps language develop, but what matters much more is the interaction, ”said the study’s lead author, Frederick Zimmerman, an associate professor in the School of Public Health at the University of California, Los Angeles. The researchers also found that TV viewing didn’t have much of an effect—positively or negatively—as long as it wasn’t displacing conversations between an adult and a child.
The UCLA study included 275 families with children between 2 months and 48 months old. They represented a variety of incomes and education. The researchers found that, in an average day, children heard about 13, 000 spoken words from adults and participated in about 400 adult-child conversations a day.
Assessed separately, factors positively associated with language development included each additional 100 conversations a day and each 1, 000 words increase in the number of words spoken by adults and heard by children. When looked at alone, TV was negatively associated with language development. But, when these three factors were analyzed together, the only one that stood out was conversation between adults and children.
“The more a child speaks and interacts with an adult, the better idea a parent has about where the child is”, Zimmerman said. “Although it’s mostly done unconsciously, parents will provide feedback and correct mistakes. They’ll also tailor their speech to the child. Parents can give the children words by talking to them about what they’re doing, such as, ‘I’m putting on your pajamas now’. But give your child the opportunity to talk, hopefully without the rest of the noise in the environment, ”she added. “If parents can carve out some conversation time—maybe at bath time or at dinner time—that’s a wonderful thing. ”
1. The researchers also found that TV viewing .
A. could have a positive effect on a child’s language development
B. had a little effect on a child’s language development
C. affected a child’s language development more negatively than positively
D. affected a child’s language development both negatively and positively
2.Frederick Zimmerman would probably agree that .
A. parents should let their children talk most of the time
B. children should watch TV programs selectively
C. the conversation between parents and children should be two-way
D. it’s no good for parents to correct their children’s mistakes when they are speaking
3. We can conclude from the last paragraph that .
A. parents should let a child repeat what he or she says
B. bath time or dinner time is the best chance for parents to talk to a child
C. parent-child conversation can be carried out at any proper time
D. parents should leave a child talking alone
4. What would be the best title for the passage?
A. Talk with kids, not at them
B. Let your children voice their own opinions
C. How to develop a child’s language ability
D. The importance of early child language development
5.The underlined word “tailor” in the last paragraph can be best replaced by .

A set of textbook designed to help high school student learn about Chinese traditional culture is to be published soon, Beijing Times reported on Monday.
The books are the first national-level works of their kind and have been developed by a working group that promotes traditional culture. They will be used by students from autumn this year, the report said.
The set contains four classics from ancient times. Two of the works, The Confucian Analects and Mencius, are for 10th-grade students, while the other two, Great Learning and Dao De Jing, will be used by 11th graders.
The initiative follows a series of steps the authorities have taken in recent years to spread and promote traditional Chinese culture on campus.
Last April, the Ministry of Education released a series of guidelines requiring the inclusion of more information about traditional culture in primary and middle school textbooks, especially those used for subjects such as Chinese Language, history, art and physical education.
The guidelines said students’ knowledge of traditional culture will be tested in the senior high school entrance examination and the gaokao, the college entrance exam.

People who have the habit of texting (发短信) while walking tend to develop a robot-like posture, lose their balance, and involve themselves in traffic accidents, according to a research from the University of Queensland. Researchers said that text-walkers are in danger of walking into traffic and train tracks among others. They suggest pedestrians（行人）stop aside, type a text and then continue walking.
For the study, the researchers tracked body movements of 26 young men and women while walking in a straight line over a distance of about 8.5 m ---once without a mobile phone, once while reading a text message and once while typing a message.
They found that participants’ body movements were greatly changed when they used their phone. The difference in their posture was more prominent while sending a text than while reading a message. They further said that when those people began texting while walking, they slowed down their pace, went off course and moved their necks less than when reading a message.
“We found that they ‘locking’ their arms, trunk and head together walked with a posture that was robot-like, all in aid of keeping their phone in their field of vision. So there is less movement between each of their body parts.” Researcher Siobhan Schabrun said, Daily Mail UK reports.
“In recent years, there have been many reports of people involved in traffic accidents because they were texting while walking. The number of pedestrian accidents is rising and texting has been blamed,” Schabrun said.
Despite such repeated accidents, only few studies have analyzed the impact of texting on body language. If more studies concentrate on walking styles adopted while texting, their findings can be used to lower whole accidents.
While a few U.S. states have introduced laws on texting while driving, Fort Lee, a New Jersey town, went further ahead and recently fined some walkers an $85 for catching them texting. It is hoped that other American states and countries will follow.
1.How did the researchers carry out their research?
A. They called on most pedestrians.
B. They tried texting while they were walking.
C. They followed some pedestrians in the street.
D. They showed pedestrians the danger of texting.
2. The underlined word “prominent” in Paragraph 3 probably means _____.
A. obvious B. important C. uncertain D. puzzling
3. When texting, the pedestrians walk in a different way to _____.
A. avoid losing their balance
B. attract other people’s attention
C. keep their eyes steady on the phone
D. take part in the study with the researchers
4. From the last paragraph, we can infer that texting while walking ______.
A. is not popular with many people
B. will make each American fined $85
C. will be punished in some states of America
D. has been forbidden in most American states
5.What is the best title of the passage?
A. Negative effects of texting.
B. Texting and traffic accidents.
C. Texting and people’s health.
D. Ways to avoid traffic accidents.

Computer scientists have hoped to give robots technical skills to help them recognize, process and react to humor. But these attempts have mostly failed. AI (人工智能) experts say that in many cases, attempts to make robots understand humor end up producing funny results, but not in the way they were supposed to.
Tristan Miller studied more than 10,000 puns (双关语) in one research project. The pun is a kind of joke that uses a word with two meanings. For example, you could say, “Balloons do not like pop music.” The word “pop” can be a way of saying popular music; or can mean the sound a balloon makes when it explodes. But a robot might not get the joke. Tristan Miller says that is because humor is a kind of creative language that is extremely difficult for computer intelligence to understand.
Allison Bishop is a computer scientist and she also performs stand-up comedy. She explained that machines are trained to look for patterns. Comedy, on the other hand, relies on things that stay dose to a pattern, kit not completely within it. To be funny, humor should also not be predictable, Bishop said. This sets a great obstacle for a machine to recognize and understand what is funny.
Bishop says since robots have great difficulty understanding humor, she feels like it gives her better job security as a comedy performer. It even made her parents happy when her brother decided to become a full-time comedy writer because it meant he wouldn’t be replaced by a machine, she added.
Despite the difficulties, Darmstadt University’s Miller says there are good reasons to keep trying to teach humor to robots. It could make machines more relatable, especially if they can learn to understand sarcasm (讽刺), he noted. Humans use sarcasm to say one thing but mean another. But Kiki Hempelmann thinks differently. “Teaching AI systems humor may make them find it where it isn’t, and they may use it where it’s inappropriate,” he said. “Maybe bad AI will start killing people because it thinks something is funny,” he added.
1.What does the author most probably want to show in Paragraph 1?
A.Robots’ influence on the scientific development.
B.Robots’ challenges of making sense of humor.
C.Computer scientists’ devotion to technical skills.
D.Computer scientists’ concern about AI’s development.
2.Examples mentioned in Paragraphs 2 and 3 are intended to ___________-.
A.prove robots do poorly in funny work
B.explain robots aren’t as intelligent as humans
C.describe language is complex and changeable
D.show language can’t be taught in a set pattern
3.What does the underlined word “obstacle” in Paragraph 3 mean?
A.Barrier. B.Record.
C.Message. D.Possibility.
4.What can we infer about teaching AI system humor from the last paragraph?
A.It will end up in vain.
B.It may be a double-edged sword.
C.It may help improve humans’ humor.
D.It will attract more computer scientists.

Chinese researchers say they have come up with a simple way to find out a person’s biological age —how much the body has aged physically – through a urine (尿) test.
Their findings will help researchers conduct numbers of ageing studies and even predict a person’s risk of age-related diseases, according to a paper published in the journal Frontiers in Ageing Neuroscience.
Another paper by researchers at the Beijing Hospital and the West China Hospital in Chengdu, Sichuan province, said on Tuesday that people aged at different rates due to changes in their genetic make-up and their environment.
Chronological age – which is based on one’s birth date —was an inaccurate measure of biological age so a more accurate method was needed, the team said.
Ageing is driven by the lifelong gradual accumulation of a broad variety of molecular (分子) faults in the body’s cells. The team said they had identified a matter —8-oxoGsn — that indicated increases in oxidative (氧化性) damage in urine as people’s bodies aged.
Cai Jianping, a co-author at the Beijing Hospital, said: “As we age, we suffer increasing oxidative damage and so the levels of oxidative matters increase in our body.” The team tested the levels of 8-oxoGsn in urine samples from 1,228 Chinese people aged two to 90 and concluded the marker helped accurately determine the stage of biological ageing in adults.
They had previously found that 8-oxoGsn levels also increased with age in the urine of animals such as mice.
The team has also developed a rapid analysis technique called ultra-high-performance liquid chromatography, which can process up to 10 urine samples an hour, according to the study.
1.Scientifically speaking, by what does a doctor judge the stage of a person getting old?
A. His biological age. B. His condition.
C. His psychology. D. His chronological age.
2.What are the outer factors the speed of one’s ageing physically depend on?
A. One’s birth date.
B. The increases in oxidative damage in urine.
C. The accumulation of various molecular faults in the body’s cells.
D. The changes in their genetic make-up and their environment.
3.Which can take the place of the underlined word “marker” in the sixth paragraph?
A. Molecular faults. B. 8-oxoGsn.
C. Oxidative damage. D. Stage of biological ageing in adults.
4.What is the passage about?
A. Why people are ageing.
B. How to delay people’s ageing physically.
C. A rapid method with which to judge how much people are aging physically.
D. What determines the stage of people’s ageing physically.
