2 . 【CHINA DAILY】In recent months, technologies have significantly increased China’s efficiency in the fight against COVID-19, among which two have brought great changes and benefits to our daily lives during the outbreak.
Driverless delivery drone
Since the beginning of the year, most people have stayed home to protect themselves from the novel coronavirus.But that means getting food and supplies from outside can be troublesome.To solve this problem, Chinese online retailer (零售商) JD.com adopted many driverless delivery vehicles to work for their customers in February.Navigated (导航) by radar and sensors, the robots can avoid barriers and pedestrians, respond accordingly to traffic signals and make their way to delivery sites, according to China Daily.“The smart robot can not only deliver supplies to us, but also reduce the possibility of infection by contact.It is such a big help for us,” a citizen in Wuhan told People’s Daily.
Infrared imaging thermometer (红外成像体温计)
To prevent the virus spreading, people in China are required to check their temperatures when they go to public places during the pandemic.But it’s risky for people to use an ordinary thermometer, which relies on direct contact to measure temperature.This is where the infrared thermometer comes in handy.According to the Telegraph, infrared imaging technology uses a lens (镜头) to focus on the light coming from an object in the form of infrared rays, then detects heat patterns and gives accurate readings over temperatures.It can be used as far as three meters away from people without any contact.

3 . Misfortune sneaked into my family when I was thirteen.First, my mother fell ill and was hospitalized; then my father, in poor health himself, was filled with anxiety and worry.Both had to stay in the hospital, leaving my younger sister and me alone at home.
As the sun set in the west, fear rose in my heart.In the dim of night,the hills beyond the village loomed in a ghostly shape on the windows of our spacious room; the frightening howls of wolves often scared us out of our sleep.
Our cries for help were unlikely to reach the villagers, for our home was located in the school some distance away from the village.Suddenly I thought of the whistle my mother used for PE classes.I took out the whistle and, drawing a deep breath,I blew it as loudly as possible.Before long,a bustle of footsteps and voices came nearer and nearer,and flashlight beams crisscrossed outside our windows.Hearing my name called,I went to open the door, and there in front of me stood a group of familiar villagers, each with a hoe on the shoulder.The very sight of their kind faces and deeply concerned eyes drove the fear away from my heart.
“Now go to sleep, kid.We are staying out here tonight!” said one old man.Resting their hoes against the wall, they sat or squatted nearby,smoking Chinese pipes or chatting in loud voices....Gradually,I fell asleep.They didn't leave until daybreak; and at dusk they came again, banging their hoes on the flagstones as if to tell me: Don't be afraid, kid,we are here with you.No one dares to hurt you!
Afterwards, the bustle of footsteps and the clatter of hoes could be heard every night around our home as if on schedule.I know what they actually meant by making the "noises" was to remove fear from my mind and reassure me: they were right outside our windows!
Ever since then,I have been convinced that sound has "temperature" and that it can warm the hearts of lonely, fear-stricken people.

5 . Autism Spectrum Disorder(ASD)(孤独症）is a disability that can cause serious social,communication and behavioral problems.There is often nothing about how people with ASD look that makes them different from other people,but people with ASD may communicate,interact,behave,and learn in ways that are different from most other people.The learning,thinking,and problem-solving abilities of people with ASD can range from pretty good to extremely bad.Some people with ASD need a lot of help in their daily lives;others need less.
People with ASD often have problems with social,emotional,and communication skills.They might repeat certain behaviors and might not want change in their daily activities.Many people with ASD may also have difficulties learning,paying attention,or reacting to things.Signs of ASD begin during early childhood and probably last throughout a person's life.
Diagnosing(诊断）ASD can be difficult since there is no medical test,like a blood test,to assess the disorders.Doctors look at the child's behavior and development to make a judgement.ASD can sometimes be diagnosed at 18 months or younger.By age 2,an experienced doctor can be considered very reliable in diagnosing ASD.However,many children may not see a doctor until much older.
There is currently no cure for ASD.However,research shows that early treatment services can improve a child's development.Early treatment services help children from birth to 3 years old(36 months)learn important skills.Therefore,it is important to talk to your child's doctor as soon as possible if you think your child has ASD or other developmental problems.
We do not know all of the causes of ASD.However,most scientists agree that genes are one of the highest risk factors that can make a person more likely to develop ASD.
If you think your child might have ASD or you think there could be a problem with the way your child plays,learns,speaks,or acts,contact your child's doctor,and share your concerns.If you're not sure who to contact,call the Early Childhood Technical Assistance Center(ECTA)at 919-962-2001.Or visit the ECTA website:https://ectacenter.org.

6 . An online tool has been released(推出）which is able to bring black and white photographs to life by adding colour to them using artificial intelligence(AI).
Colourisation(上色）of old photos is normally a process taking a lot of time,which requires special training and expensive software.The tool,ColouriseSG,is able to do it for free. It is trained on old pictures and uses machine learning to guess what it thinks the pictures would have looked like in colour.
＂The purpose of colourisation is to produce a picture with colours that seem to be right," the tool's developers say."It by no means makes sure that the colourised picture is an accurate（精确的）representation of the original photo in time."
The free-to-use tool was developed to provide an accurate way for people from Singapore to edit their black and white pictures.The idea of ColouriseSG was to provide a large enough data-set to be linked to people living in Singapore.
Tech firm NVIDIA has released several different picture editing tools that are powered by AI.Its latest release is software which uses deep learning to turn even the roughest drawings into works of art.
The new program,GauGAN,named after famous French impressionist Paul Gaugin,uses a tool called GAN to recognize simple lines and turn them into realistic pictures.
Its application could help jobs,for example,urban planning,edit pictures faster and with greater accuracy,according to the company.
“It's much easier to come up with designs with simple drawings,and this technology is able to turn these drawings into highly realistic pictures,"said Bryan Catanzaro,vice president of applied deep learning research at NVIDIA.
1. How does ColouriseSG colourise photos?| A．By learning from people in Singapore. |

7 . Scientists have proved that petting cats and dogs for just ten minutes is an effective way to reduce stress levels.
Scientists showed that the general well-being of students improves quickly, with even those who are highly stressed showing ''significant'' reduction in cortisol levels - a chemical produced by our bodies in times of stress.
Many universities have adopted ''Pet Your Stress Away'' programs where students can interact with cats or dogs and it appears to be paying dividends now.
The research, conducted by Washington State University, shows that pets improve students' moods and their presence has stress-relieving physiological benefits. ''Just 10 minutes can have a significant impact, '' said Patricia Pendry, an associate professor in WSU's Department of Human Development. ''Students in our study that interacted with cats and dogs had a significant reduction in cortisol, a major stress hormone. ''
This is the first study that has demonstrated reductions in students' cortisol levels during a real-life intervention. The team chose 249 college students and put them into four random groups and compared the effects of different exposures to animals.
The first group were provided 10 minutes of hands-on interaction with dogs and cats.
The second group waited in line while observing others petting the animals.
The third group watched a slideshow of the same animals, while the fourth group was ''waitlisted. ''
Salivary cortisol samples were collected from each participant starting from the moment they woke up in the morning.
There were significantly less cortisol in the saliva of students who had direct interaction with the pets.
''We already knew that students enjoy interacting with animals, and that it helps them experience more positive emotions, '' Dr Pendry said.
''What we wanted to learn was whether this exposure would help students reduce their stress in a less subjective way. ''
''And it did, which is exciting because the reduction of stress hormones may, over time, have significant benefits for physical and mental health. ''
1. What can we learn from the passage?| A．The more stress you have, the less cortisol your body produce. |
| B．Washington State University has adopted ''Pet Your Stress Away'' programs. |
| C．The reduction of stress hormones can merely be beneficial to students’ mental health. |
| D．All groups didn’t interact with dogs and cats for ten minutes. |

8 . The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world’s ecological balance.
On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other species that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.
On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.
Both locally and globally, the continued spread of full-sun coffee plantations could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic soil conditions.
It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.
1. What can we learn about full-sun coffee production from Paragraph 4?| A．It leads to air pollution and global warming. |
| B．It limits the spread of new growing techniques. |
| C．It slows down the loss of shade trees. |
| D．It improves local soil conditions. |

10 . Two Earthquakes in Two Months:
Comparing the Quakes in Haiti (海地) and Chile (智利)
Overview (概要) How do the earthquakes in Chile and Haiti compare? Here, students perform a gallery walk to learn more about the earthquakes from a specific point, and then do a specific research and presentation project or response activity. Finally, they seek answers to their unanswered questions.
Materials Print copies of photographs, charts, documents and other visuals to display, as described below; computer (s) with Internet access (optional), research materials, handouts.
Warm-up Choose and prepare a “gallery” of photographs, graphics, news reports and other materials to display around the room to enable students to consider the 2010 earthquake in Chile.
Depending on course program, choose materials for the gallery that provide a window on the two quakes, through one of the following specific points, or the focus of your choice:
Earthquakes through History Putting the 2010 Chilean and Haitian quakes into historical view related to other earthquakes, including the 1960 Chilean quake and the 2004 Asian earthquake and tsunami.
Rescue and Aid Considering domestic and international response to the disasters by militaries, governments and aid organizations, including rescue and recovery as well as efforts to provide food, water, health care and shelter to those affected.
Related The article Underwater Plate Cuts 400 Mile Gash compares several earthquakes:
Mr. Lin figured that the quake on Saturday was 250 to 350 times more powerful than the Haitian quake.
But Paul Caruso noted that at least on land, the effects of the Chilean tremor (震动) might not be as bad. For one thing, he said, the quality of building construction is generally better in Chile than in Haiti. And the fact that the quake occurred offshore should also help limit the destruction. In Haiti, the rupture (断裂) occurred only a few miles from the capital, Port-au-Prince. The rupture on Saturday was centered about 60 miles from the nearest town, Chillan, and 70 miles from the country’s second-largest city, Concepción.
