How to keep yourself safe from new virus?
After a new-type coronavirus was detected in viral pneumonia cases in Central China's Wuhan city a month ago, more cases have been reported in recent days. To prevent catching the infection, here’s what you can do:
1. Wear masks outdoors
●Wearing a mask is one of the most effective ways to protect you from getting infected.
●1.
●If you’re not feeling well or have symptoms of fever, a mask is also needed to prevent you from spreading germs to others.
2. 2.
Cover your mouth and nose with a tissue when you cough or sneeze, or you can cough or sneeze into your sleeve, but avoid covering with your hands directly.
3. 3.
Wash your hands with soap and running water thoroughly for at least 15 seconds.
● Before eating and after using the toilet
● After returning home
● After touching trash or garbage
● After contacting with animals or handling animal wastes
4. Strengthen your immune system and exercise regularly
● Exercise regularly is one of the most important ways to help you stay away from catching any infections.
● Make sure that shared spaces have good air flow and avoid going to crowded places such as hospitals, railway stations and airports. Wear a mask if transport or movement is necessary.
● Seek prompt medical attention 4..
● Avoid close contact with people who have flu or cold-like symptoms.
●5.. Avoid contact with wild animals or farmed livestock without any protection.
A.If your hands are not visibly dirty
B.Eat thoroughly cooked meat and eggs
C.Wash your hands frequently and properly
D.Protect yourself and others from getting sick
E.if you have symptoms of fever and respiratory infection
F.Cover your coughs and sneeze with tissue

Rivers are the veins of the Earth, transporting the water and nutrients (营养物) needed to support the planet’s ecosystems, including human life. While many nutrients are essential to the survival of life, there is one element transported by water in rivers that holds the key to life and to the future of our planet — carbon.
Carbon is everywhere and understanding the way it moves and is either released or stored by the Earth system is a complex science in itself. Carbon starts its journey downstream when natural acid rain, which contains carbon dioxide from the atmosphere, melts minerals in rocks. This helps transform carbon dioxide to bicarbonate (碳酸氢盐) in the water that then flows in our rivers. This is a very long process, which is one of the main ways carbon dioxide is removed from the atmosphere. Carbon is transported by rivers to oceans and once that carbon reaches the ocean, it is stored naturally in deep sea sediments (沉淀物) for millions of years.
As carbon travels down a river, different processes may impact whether it continues to flow downstream or whether it is released into the atmosphere. For example, human engineering, like extensive dam construction, will result in dramatic changes to how water and sediments travel down the river. Some carbon that fails to reach the sea may return to the atmosphere in some way, which causes more warming.
Earth’s climate is closely related to the carbon cycle. We all know about the essential role of plants in consuming carbon dioxide, but do we know enough about rivers? Changing the chemistry and the course of rivers may have significant impacts on how they transport carbon. Remember: wherever we live, we all live downstream.

Education officials and industry experts are debating the future of online learning. The discussion is important because hundreds of universities in the United States have recently moved classes online because of the spread of the novel coronavirus（冠状病毒）.
For Asha Choksi, the rise of Internet-based or online study programs has led to major improvements in higher education. “It’s actually given a lot more power to students in terms of how, when and where they learn,” the head of research for Pearson Education said.
Classes meet online through video conferencing. In this way, students are able to communicate with each other and their professors even when they are far away from school. However, recent research suggests the majority of college students and professors prefer in-person instruction, because they are concerned that companies supervising（监管）online learning programs are not clear about the policies the schools have.
“Students see in-class lectures as opportunities to engage with instructors, peers, and content.” the researchers wrote. In-person learning is especially important in fields like healthcare and teaching. Online education can never really take its place, said Stephanie Hall, a fellow with the independent policy research group The Century Foundation. “Students need to experience...what they’re learning about, reading about or hearing about in the classroom. And I don’t know yet the degree to which technology can facilitate that.”
“When schools make agreements with online program managers to run their online programs, they often do not make important information available to students,” Hall said. This includes how much control the company has over the design of the program or whether the teacher leading the classes was involved in their design. In addition, many colleges and universities advertise online programs as a low cost opportunity for students. But in some cases, students attending in-person classes get financial aid and online students do not.
1.What does Choksi think of the online study programs?
A.They offer students more choices in study.
B.They reform the country’s education system.
C.They provide advanced scientific knowledge.
D.They promote the development of technology.
2.According to most college students and professors, what’s the advantage of in-person learning?
A.It is convenient.
B.It costs less to study.
C.It can better meet school policies.
D.It can improve students’ communication skills.
3.What does the underlined word “facilitate” probably mean in paragraph 4?
A.change B.apply
C.achieve D.control
4.What is Hall’s attitude towards online education?
A.Hopeful. B.Critical.
C.Uncaring. D.Neutral.
When she was ten years old, Isadora Duncan dropped out of school to teach people dance. If that job was left to any other ten-year-old, it would have turned out frustrating, difficult, and a little discouraging.
But Duncan was different. Not only was she already talented enough to earn money even at that age, but she also had a rare kind of confidence that helped her treat troubles as fuel —something to elevate the fire that is already burning inside of her.
It’s no surprise, then, that when she moved to New York to join a theatre company, she found herself restricted. The existing dancing style, their way of operating—all of this seemed to her the work of a misguided past. Duncan was very direct about what she wanted, confidently telling people she had a different vision of dance that she was going to spread in the world. This, naturally, led to ridicule and laughs early on, but as she built up her work, these instances became less frequent. Today, she is remembered as “The Mother of Dance,” with much of the modern art owing its expressive style to her influence. Inspired by the ancient Greeks, she brought the style to life.
In her autobiography (自传), one of the things Duncan frequently refers to as the basis of her expressive spirit is the fact that she had a childhood where she wasn’t constantly watched. The expectations of her mother (who raised her) were open-ended. It was the freedom of this lifestyle that drove her to see what she could do.
Growing up, before she left school, she was told one of two things: that she was either completely useless or that she was a genius. There was nothing in between. Even when she started working, people either bowed to her or they basically ignored her. But there wasn’t one moment Duncan doubted her own genius.
There is an old quotation “if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.” And it captures an important truth. At school, Isadora Duncan was a failure. In the dance hall, she gave form to brilliance.
1.What does the underlined phrase “treat troubles as fuel” mean?
A.Duncan used troubles to push her forward towards her dream.
B.Duncan was good at burning away everyday troubles.
C.Troubles turned Duncan into a confident girl.
D.Troubles lit the fire of dancing in Duncan.
2.Which of the following is TRUE about Duncan?
A.Her experience in New York was the foundation of her career.
B.Her teaching job when she was little destroyed her confidence.
C.Her dancing style was not very well received at the beginning.
D.Her mother set higher expectation on her than she could bear.
3.What does the author try to tell the readers in the last paragraph?
A.It is useless climbing a tree to catch fish.
B.Everybody is a genius in his own way.
C.Miseries come from human stupidity.
D.Teachers can impact students greatly.
4.What is this passage mainly about?
A.Isadora Duncan’s childhood and her achievements today.
B.Duncan’s career development and other dancers’ opinions of her.
C.Isadora Duncan’s early experiences and the reasons for her success.
D.Duncan’s high status in the dancing world and her unique expressive style.
Dear 17﹣year﹣old self，
When your Laker dream comes true tomorrow， you need to figure out a way to invest in the future of your family． This sounds simple， and you may think it's a no﹣brainer， but take some time to think on it further．
I said INVEST．
I did not say GIVE
Let me explain．
Purely giving material things to your siblings（兄弟姐妹） may appear to be right decision． So you buy them a car， a big house， pay， all of their bill． You want them to live a beautiful comfortable life， right？
But the day will come when you realize that as much as you believed you were doing the right thing， you were actually holding them back．
You will come to understand that you were taking care of them because it made YOU feel good， it made YOU happy to see them smiling and without a care in the world ﹣ and that was extremely selfish of you． While you were feeling satisfied with yourself， you were slowly eating away at their own dreams and ambitions． You were adding material things to their lives， but subtracting the most precious gifts of all．
Invest in their future， don't just give．
Use your success， wealth and influence to put them in the best position to realize their own dreams and find their true purpose． Put them through school， set them up with job interviews and help them become leaders in their own right． Hold them to the same level of hard work and dedication that it took for you to get to where you are now， and where you will eventually go．
I'm writing you now so that you can begin this process immediately， and so that you don't have to deal with the hurt and struggle of weaning（断绝） them off of the addiction that you facilitated That addiction only leads to anger， hatred and jealousy from everybody involved， including yourself．
As time goes on， you will see them grow independently and have their own ambitions and their own lives， and your relationship with all of them will be much better as a result．
Trust me， setting things up right from the beginning will avoid a ton of tears and headache， some of which remains to this day．
Much love，
