Coronaviruses(冠状病毒)are a large family of viruses that cause disease in mammals and birds. Coronaviruses can cause illnesses that range the common cold to many more severe illnesses.
The (new) identified virus, called COVID-19, is thought to have spread to humans from wild animals sold at a market in Wuhan, in (centre)China's Hubei Province. But it is now spreading between people. Chinese officials say disease is able to spread from one person to another even before any actual signs appear, makes it especially hard to contain.
Signs of some patients (affect)by the disease have included fever, cough, shortness of breath and general breathing difficulities. In some more severe (case), the virus can cause pneumonia(肺炎). Some people report few or no signs, while others have gotten very sick or even died. There is no special (treat)for the new coronavirus at present.

Homework is made up of out-of-class activities and at-home activities teachers assign to students. It can include practice assignments that emphasize newly acquired skills. Projects that have to be worked on in agreement with schoolwork also form a part of homework.
For example, to complete their homework in time, children start dividing their time into studying and playing, thus learning to complete their scheduled tasks within the time they have. They learn to do things on their own. They manage their time and complete their work independently.
Homework can also help build up children's confidence. Teachers' positive remarks can help develop students' confidence and encourage them to keep up with their good work.
In addition, homework gives students a chance to learn from their mistakes and overcome their weakness. It provides them with a platform to express what they know or have newly found, and exhibit their talents. This helps them improve their academic results.

Is Society Too Dependent On Technology?
Just think, what would happen if your computer, iPad or laptop crashed today? What if someone took away your phone for some days or perhaps you lost it? Today, most people are becoming dependent on technology.
Most of us cannot go for a minute without looking at our phones and the fear of the battery dying is immense. If you happen to work in offices you may be familiar with this trend. Anyway, it's true. How can work continue if it's hard to send an email to a colleague or customer? This is common in almost all offices.
Kids used to spend a lot of time with each other or parents playing or just sharing stories. Those evening games after school are over; watching cartoons on a Sunday or playing with friends are no longer there. Technology has taken all their time.
Society may have gone too far in technology dependence. It has become so immense that doctors have recommended for “technology detox”. If not, according to Oxford Dictionary, Technology Detox is a period during which an individual avoids using any electronic devices including computers, smart phones, etc., as a chance to reduce stress and focus on social interaction in the outside world.
Well, the choice remains in our hands. We must agree that society is being carried away by the increased inventions being introduced in our lives today. Meanwhile, we should have the discipline to turn it off when we are supposed to experience life in reality.
A. Perhaps you may have heard of it.
B. We appreciate technology since it has its benefits.
C. If the Internet is down, all the tasks are over for the day.
D. Technology addiction has become a major problem among teenagers.
E. If thinking about these incidences makes you stressed, you are not alone.
F. Here are some signs that our generation depends too much on technology.
G. Today, most kids remain indoors playing computer games or with a smart phone.

In ancient times, our ancestors relied on stars to guide them on a clear night. Today, we have navigational systems to help us find our way, with the latest being the Beidou Navigation Satellite System (BDS).
The BDS is entirely built by Chinese engineers. With the of the last satellite from the Xichang Satellite Launch Center on June 23, the global network of 59 satellites has been completed. On July 31, Beidou started providing full-scale global services. It's difficult to imagine the great those satellites, orbiting (围绕……运转) the Earth, have on our daily lives.
When you unlock one of Hellobike's bicycles, you are using the BDS. The popular bike-sharing company came out with two new bike models this year that are with the positioning service. "The intelligent lock on each bike receives Beidou satellite and sends positioning information to the data center, which will help collect big data on the bikes and estimate users' riding in advance according to the data," Chu Yiqun, a manager of Hellobike told Xinhua News Agency. Users can also find shared bikes more accurately thanks to Beidou's global positioning accuracy of 2.34 meters.
However, the BDS doesn't just work one way. As the country's largest space-based system and one of four global navigation networks, along with the United States' GPS, Russia's GLONASS and the European Union's Galileo, Beidou a unique two-way communication system, including its ability to receive messages sent by people from areas with poor communication signals. Obviously, this exclusive function isn't designed for users to chat online. Instead, it plays a role when disasters occur and communications are blocked.
After the Wenchuan earthquake in 2008, all ground-based communication were interrupted. Though the first generation of Beidou could only send 120 characters in a single message at that time, communication between areas and rescue centers was successful. Now, Beidou's messaging capacity has been increased to 1,200 Chinese characters in a single message. It is widely used in disaster , automatic identification and information release.
As Sun Jiadong, former chief designer of the BDS said: "The application of Beidou is only by imagination."

Every child should know some basic first aid skills. This is true whether your child is four or fourteen.
Calling for help
Once your child reaches the age of four, he should know all about calling 911 in the event of an emergency.
For example, he should call 911 if an adult asks him to, if an adult passes out and cannot be woken, if there is a fire and he can't findan adult, or if people are hurt.
As I am typing this, I just realized that although my kids are taught about 911, the telephones inthe house are out of reach for all but my oldest child (to prevent the other two from playing with the phone). Don't make this mistake yourself. You do hope your children can get in touch with the police intime.
Teach children about basic care for cuts and scrapes. In my house, the kids all know that cuts must be cleaned and know where the bandages are. Asking an adult for help is necessary. Also they should know a bit about self-care. Believe it or not, I had to help a teenage neighbor once who had no idea what todo when he cut his hand on broken glass. He just ran around in a circle.
Burns
Tell your child that ifhe ever gets aburn, he should immediately call for help. Meanwhile, he should run the cool but not cold water for the burn. Getting a burn cooled down quickly can reduce the damage to the skin.
A. Cuts and scrapes
B. Tell them what 911 is about.
C. Set an example for your children.
D. Explain all about what a real emergency is.
E. You should teach your children something useful.

Some people are great at remembering faces. While, for some people, remembering face can be difficult. Even for others, it is much worse. Such people have a condition (call)"face blindness". Its actual name is DP, is short for Developmental Prosopagnosia.
Experts say DP can differ (great) from patient to patient. In less severe cases, people are unable to describe the face of someone they have just met. In severe cases, people cannot even recognize (they)own children in a group photo.
Those who have DP show no clear signs. Take Dacia for example. If you met her, you probably wouldn't know that she suffered brain damage as a child. There would be no sign of it until you meet her a second time. She wouldn't remember you at all. Dacia has mostly recovered from her (injure). But now, she suffers from face blindness.
In the past, face blindness (think) to be very rare. But recent studies have shown that it might be more common experts thought. The study on face blindness will not directly lead any treatments(治疗). However, it may offer a much (deep) understanding of how we remember the world around us.
Do you want to create more successful writings? Perhaps you can benefit from the following suggestions on excellent writing.
You need time. A lot of smart people lie to themselves like, "I finish my task best at the last minute." In fact, it's not true. Sure, you are smart, but you still need to have some pressure. For example, if you are working on an important topic, why do you think that you can write well at midnight just before the conference? Writing can be a miracle if you are given enough time.
Writing requires practice. Would you do nothing before running a marathon? No you would practice running gradually to make your body stronger. In order to become a writer, you need to write.

D. Exchange papers with peers or an instructor.

There's no electricity or water and even no textbooks either! I'm still trying (adapt) to these conditions. However, one thing is for sure, I've become more (imagine) in my teaching. Science is my most (challenge) subject as my students have no concept of doing experiments. In fact there (be) no equipment, and if I need water I have to carry it from my house inbucket! The other day I (show) the boys the weekly chemistry experiment when, before I knew it, the mixture was bubbling over everywhere! The boys had never come across anything like this before started jumping out of the windows. Sometimes I wonder how relevant chemistry is these students, most of whom will be going back to (they) villages after Year 8 anyway. To be honest, I doubt whether I'm making any difference to these boys' (life) at all.
孩子们有良好的衣食供应。
I started playing the piano when I (be) five years old and still really enjoy it now. It is a perfect way to relax and it cheers me up I'm feeling down.
When I lived at home with my parents, we had lovely piano in the house. Besides, I attended piano (lesson) every week. However, when I went to university, I had to leave my family, my home and my piano behind.
I missed playing the piano so much that I spent all the money I saved on a new electric piano. I had (difficult) taking it from the music shop to my house by myself, so I took a friend with me (get) it home. When I felt tired after studying or writing a research paper, I would take a break to play something energetic, really helped remove my great stress. When I was feeling homesick, playing music made me feel much (good).
Now I'm on my year abroad and I don't have a piano any more, I still listen to a lot of classical music (write) by my favorite composers like Beethoven and Chopin. I think that, when I get home next time, I'll drive my family mad because I'll play the piano all the time.
