(CNN)A new Chinese coronavirus, a cousin of the SARS virus, has infected more than 200 people since the outbreak (爆发) began in Wuhan, China, in December. Scientist Leo Poon, who first decoded the virus, thinks it likely started in an animal and spread to humans.
"What we know is it causes pneumonia (肺炎) and then doesn't respond to antibiotic(抗生素) treatment, which is not surprising, but then in terms of mortality (死亡率), SARS kills 10% of the individuals," Poon, a virologist(病毒学家) at the School of Public Health at The University of Hong Kong, said.
The World Health Organization offered guidance to countries>Here are seven things you should know about a coronavirus.
What is a coronavirus
Coronaviruses are a large group of viruses that are common among animals. In rare cases, they are what scientists call zoonotic[?z????n??t?k](人畜共患病), meaning they can be transmitted from animals to humans, according to the US Centers for Disease Control and Prevention.
Coronavirus symptoms(症状)
The viruses can make people sick, usually with a mild(轻度) to moderate(中度) upper respiratory tract illness(上呼吸道疾病), similar to a common cold. Coronavirus symptoms include a runny nose, cough, sore throat, possibly a headache and maybe a fever, which can last for a couple of days.
For those with a weakened immune system, the elderly and the very young, there's a chance the virus could cause a lower, and much more serious, respiratory tract illness like a pneumonia or bronchitis
[br???ka?t?s](支气管炎).
There are a handful of human coronaviruses that are known to be deadly.
Middle East Respiratory Syndrome(中东呼吸综合征), also known as the MERS virus, was first reported in the Middle East in 2012 and also causes respiratory problems, but those symptoms are much more severe. Three to four out of every 10 patients infected with MERS died, according to the CDC.
Severe Acute Respiratory Syndrome(严重急性呼吸综合征), also known as SARS, is the other coronavirus that can cause more severe symptoms. First identified in the Guangdong province in southern China, according to the WHO, it causes respiratory problems but can also cause diarrhea [?da???ri?](腹泻), fatigue (疲劳), shortness of breath, respiratory distress (呼吸窘迫) and kidney failure (肾衰).

How it spreads
Viruses can spread from human contact with animals. Scientists think MERS started in camels, according to the WHO. With SARS, scientists suspected civet cats (狸猫) were to blame.
When it comes to human-to-human transmission of the viruses, often it happens when someone comes into contact with the infected person's secretions [s??kri??(?)n](分泌物).

2020年晚会现场采用裸眼3D飞屏技术来提升观看效果。
坊间有这样的传闻,如果给一个动图上加上两条竖线,就可以创造出神奇的裸眼3D效果了。
效果确实非常突出,为什么加两条白线就能做到裸眼3D呢?是不是我的大脑又一次欺骗了我?
目前绝大多数3D显示的原理,就是让观察者左眼看到的画面和右眼看到的画面有细微的差别,而这个差别和双眼在真实世界里看到的差别保持一致,观察者的大脑就会认为他眼睛看到的是个三维实体而不是一个平面画面。
