1 . On December 26, 2004, an earthquake along the Indian Ocean caused a huge tsunami(海啸)that killed thousands of people in Asia and East Africa. However, wildlife officials at Sri Lanka’s Yala National Park reported there had not been many animal deaths.
Some researchers believe the animals at the park were able to sense the earthquake and moved to higher ground before the earthquake hit. Animals have good senses that help protect themselves from being hunted by their natural enemies. It is thought that their senses might also help them sense the coming disasters. Several countries have done research on the prediction(预测)of earthquakes by animals. There are two theories(理论)about how animals may be able to sense earthquakes. One theory is that animals sense the earth’s shake. The other is that they can sense changes in the air. However, so far there has been no strong evidence about how animals may be able to sense earthquakes.
Other researchers are skeptical(怀疑)about using animals for earthquake predictions. The United States Geological Survey(USGS)officially states, “Changes in animal behaviors cannot be used to predict earthquakes. A connection between a specific behavior of an animal and an earthquake has not been made. Because of their fine senses, animals can often feel the earthquake at its earliest stages before the humans. That’s why people say that the animal knew the earthquake was coming. But animals can also change their behaviors for many other reasons. If an earthquake can shake millions of people, it is likely that a few of their pets will, by chance, be acting strangely before the earthquake.”
Although scientists disagree on whether animal behaviors can be used to predict earthquakes, they all agree that it is possible for animals to sense changes in the environment before humans. Researchers around the world are continuing to study the connection between animal behaviors and earthquakes. It is hoped that these studies will help to predict earthquakes.

6 . A snow leopard（雪豹）research team said one of its infrared（红外的）cameras caught some snow leopards playing in a national park in the east end of the Qilian Mountains, which the team leader said is “of great significance”.
There have been suspected sightings of snow leopards in east Qinghai before, but none has ever been confirmed.
The snow leopard, often found near the alpine snowline in the Asian heartland, has been called “the king of snow mountains”. It is a Class-A protected animal in China and is classified as “vulnerable” by the International Union for Conservation of Nature.
“Based on these images, we can conclude that the area has a certain number of snow leopards, but the exact population is yet to be calculated,” said Ulgi, an official at the reserve.
In fact, in the snow leopard project, a number of high-tech equipment have been increasingly used in monitoring and protecting the species, such as infrared cameras, drones（无人机）and DNA research based on the animal’s excrement（排泄物）. “Still, more should be done to protect the snow leopard, which is vulnerable to challenges such as climate change, habitat loss and human activities,” he said.
A total of 60 infrared cameras have been scattered across the largest State-owned forest in the central and eastern Tianshan Mountains, covering an area of around 550 square kilometers, according to sources in charge of the project on February 18.
“We will keep monitoring to learn more about snow leopard activities in the Tianshan Mountains and assist the local administration to come up with more targeted protection measures,” said He Bing, snow leopard project manager.
He said that the discoveries of snow leopards and other animals in China were evidence of China’s increased efforts in environmental control, such as the protection of natural forests.

At the moment of 9:43 a.m., on Tuesday, June 23rd, 2020, at the Xichang Satellite Launch Center in Sichuan Province, the last satellite of the third-generation network was sent into space. It is the 55th member in the family of BeiDou. It belongs to China’s Beidou Navigation Satellite System. So far, 59 satellites, including the first four test ones, have been launched from Xichang. With the development of China, we have already owned three other famous satellite launch centers — Jiuquan, Taiyuan and Wenchang.
After a period of tests in space, this new satellite has started to work with other Beidou satellites together. It is designed to work for at least 12 years. So far, China has completed the third-generation network of China’s BDS. It was a new milestone in the nation’s space research work. The launch showed our country has completed our largest space-based system. It’s one of four global navigation networks, including the United States’ GPS, Russia’s GLONASS and the European Union’s Galileo.
BDS has been widely used as public resources in our daily life. It has been shared by the whole world. It will provide more services around the world. BDS is the common wealth of the development of human beings.
