1 . 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 2003.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 10-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.

2 . Work is helpful to health. Scientists find that the hard-working people live longer than those who have no jobs. Studies show that the jobless are in poorer health than job-holders. Career（ 职业的） women are healthier than housewives.
Why is work good for health? It is because work keeps people busy, away from loneliness. Researches show that people feel unhappy, worried and lonely when they have nothing to do. Instead, the happiest people are those who are busy. Many high achievers who love their careers feel them happiest when they are working hard. They work as a bridge between dream and reality, so they have energy every day. By work, people get to know each other. By taking part in all kinds of activities, they find friendship and warmth. This is helpful to health. The loss（丧失）of work means the loss of everything. It affects man's spirit and it will cause more illnesses.
Besides, work gives one a sense of hope and a sense of achievement. Work makes one feel his value and status（形象） in society. When a writer finishes his writing or a doctor successfully operates on a patient or a teacher sees his students grow, they are happy beyond（ 超越） words.
From the above, we can come to a conclusion； the more you work, the happier and healthier you will be.

3 . What does it take to graduate from university? Some papers or high scores in exams? Well, these are not enough if you are a student at Tsinghua University.
According to a new rule of the university, students must prove (证明) themselves in the swimming pool. They need to pass a swimming test of at least 50 meters, and those who fail the test will be required to take a swimming course throughout their school years. By the time they graduate, they will have known how to swim; otherwise they can’t graduate with their bachelor’s degrees (学士学位).
The news made waves in Chinese social media (媒体). Some people praised the university for requiring a necessary skill that can save lives, and they also believed that the rule would help improve students’ health. However, others questioned if it was fair to expect those who come from inland cities (内陆城市) to be able to swim.
In fact, this is not a new rule. Tsinghua University first made swimming a requirement in 1919 but later gave it up because the number of students became too large and there were not enough swimming pools in the school for them to learn swimming.
Anyway, it is still good news that Chinese students’ health has become more and more valued. Why not just take this chance to learn one more life-saving ability?
