Do you know about Psephurus gladius？ It's a Chinese paddlefish known as "king of all national freshwater fish"． However， it is announced that the Chinese paddlefish living in the Yangtze River has become extinct （灭绝的）．

A paper from Science of the Total Environment shows that the largest freshwater fish in China might have gone extinct between 2005 and 2010． Wei Qiwei， author of the paper， said in September， 2019， some experts supposed that the first﹣class protected fish had been extinct already．

The Chinese paddlefish was about 2 to 3 meters long and could grow longer than 7 meters．The fish had lived on the earth for 15 million years． The latest discovery of the fish was made in 03． Scientists helped the fish to return and tried to track （追踪） it． Unluckily， a boat accident

caused the tracking efforts to fail． Since then， no discovery has been reported and no such fish has been kept in captivity （圈养）．

"The Chinese paddlefish was so big that it was hard to raise in captivity，" Wei said．Between 1984 and 1993， he once tried to save four fish， but only one stayed alive and returned to the river．

The extinction of the fish has called public attention as people expressed sadness over the death，hoping such animals would be better protected so that future generations could see them．From Jan 1， 2020， China began a l0﹣year fishing ban （禁令） on important areas of the Yangtze River to protect Biodiversity （生态多样性） in China's longest river．

Scientists around the world are racing to create and test vaccines （疫苗） to help protect people against the novel coronavirus （新冠病毒）． They are making progress， but it will be quite a while before any vaccines are ready．

There are many different ways to make vaccines． At least 115 different vaccines for the novel coronavirus are being developed around the world right now． Many of them may not work or may have side effects that can be dangerous． That is why testing is very important．

Before a vaccine is ever tested on humans， it's first tested on animals to make sure it seems safe． Testing the vaccine on humans is done in several different phases （阶段）． In Phase 1， a small group of people are given small amounts of the vaccine to see if it has any bad effects． Phase 2 still tests the vaccine's safety， but it's mainly a test to see if the vaccine seems to work． If Phase 2 goes well， the vaccine can begin Phase 3．During Phase 3，the vaccine is tried on a much larger group of people to see how well it works．

Because of the serious and worldwide impact （影响） of the novel coronavirus， there is huge pressure to develop a working vaccine quickly．It normally takes seven or more years to develop a safe vaccine that works well． Now drug companies are hoping to create working vaccines in 12 or 18 months．

But health experts also warn that rushing too much could be dangerous． A vaccine with harmful effects could cause more problems than it solves．
