1 . A group of swans (天鹅) flew down to a beach where a crow (乌鸦) was jumping around. The crow watched them with disdain (鄙视).
“You have no flying skills at all!” he said to the swans. “All you can do is to move your wings. Can you turn over in the air? No, that’s beyond you. Let’s have a flying competition. I’ll show you what real flying is!”
One of the swans, a strong young male, took up the challenge. The crow flew up and began to show his skills. He flew in circles, performed other flying tricks, and then came down and looked proudly at the swan.
Now it was the swan’s turn. He flew up, and he began flying over the sea. The crow flew after him, making all kinds of comments about his flying. They flew on and on till they couldn’t see the land and there was nothing but water on all sides. The crow was making fewer and fewer comments. He was now so exhausted that he found it hard to stay in the air, and had to struggle to keep himself from falling into the water.
The swan pretended not to notice, and said, “Why do you keep touching the water, brother? Is that another trick?”
“No,” said the crow. He knew that he had lost the competition. “I’m in trouble because of my pride! If you don’t help me, I’ll lose my life…”
The swan took pity on him, and took him on his shoulders and flew back to the beach.

2 . Thanks to more than two decades of environmental recovery efforts, various species of wild birds have begun to gather at the mouth of the Yellow River. The Yellow River Delta National Nature Reserve in Shandong province covers about 153, 000 hectares, with wetland making up over 70% of the total area.
Wang Andong, a researcher in the reserve, said 315 oriental storks, an endangered species, were born there this year. The species is under first-class national protection in China. Wang said that, decades ago, the oriental storks only made a brief stop at the reserve before they traveled to China's warm south, but an increasing number of the birds are choosing to live in the area throughout the year.
The reserve has seen the birth of 2, 000 oriental storks since 2003 when the birds first nested there. The increase in the number of wild birds in the reserve, especially endangered species, reflects the area's improved ecology.
Wang owed the improvement to a number of wetland recovery projects, such as water replenishment and turning farmland back into wetland. A total of 155 million cubic meters of water was supplied to the reserve in July to replenish groundwater. Water replenishment, started in 2008, helps bring back the wetland and creates a better environment for fish. It ensures enough food supplies for the birds.
The rising number of wild birds in the reserve has become a feast for the eyes for bird-watchers, who are able to spot oriental storks and other wild birds even outside the reserve.

3 . China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration(渗透)by that year.
5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots self-driving cars, and the Internet of things.
The GSMA said that China's three major mobile operators-China Unicorn, China Mobile, and China Telecom-are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
One of the most distinguishing(显著的) factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China's seriousness about paying whatever it takes.
Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation's total connections will be 5G, according to GSMA. This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.
1. What will 5G bring?| A．A completely new pattern for daily life. |
| B．Excellent networks and national safety. |
| C．Amazing speeds for public transportation. |
| D．Realizing the potential in many new services. |
| A．It will develop rapidly. | B．It may be lack of government support. |
| C．It will move forward slowly. | D．It may fall behind Europe. |
| A．bring up. | B．set up. | C．turn up. | D．pick up. |
| A．More than half Koreans use 5G in 2025. | B．Chinese cannot own 5G in 2025. |
| C．Only five countries will have 5G in 2025. | D．Europe will pay little attention to 5G in 2025. |
4 . Cruz Genet, 11, and Anthony Skopick, 10, couldn’t agree. Were the birds out on the ice ducks or geese? So on a cold January evening last year, the two friends ventured (冒险) onto the frozen pond near their homes in Frankfort, Illinois, to get a better look. First, they threw a rock onto the ice to test it, Cruz told NBC 5 Chicago. “Then we stepped on it.” Convinced the ice would hold their weight, Anthony took a few steps, but then he fell through the seemingly frozen surface.
Cruz rushed to help his panicked friend. However, the pond swallowed him, too. Cruz managed to lift himself out of the extremely cold water and onto a more solid section. He then gingerly worked his way toward Anthony. But the ice didn’t hold, and he fell in again. This ime, he couldn’t get out.
The boys were up to their necks in icy water and quickly losing feeling. Any chance of their freeing themselves was slipping away. Cruz was sure that he was going to die.
Anthony’s older sister had seen the boys fall through the ice and started screaming, wishing someone to save them.
John Lavin, a neighbor driving nearby on his way to the grocery store, heard her. He quickly pulled over. Seeing the boys, he grabbed (抓住) a nearby buoy (救生圈), kicked off his shoes, and ran into the cold water, struggling his way through the ice. Lavin made his way to Cruz and Anthony and pulled them back to land.
The boys were taken to the hospital, where doctors discovered that their five- minute stay in the water had lowered their body temperature nearly ten degrees. Fortunately, they have fully recovered, though they are still a little amazed by their fearless neighbor. “Just to think,” says Cruz, “if he hadn’t been there, I could have died.”

5 . Millions of people suffer from motion sickness (晕动症). They have a lot of activities they fear. They often avoid doing these activities which include long-distance airplane travel, sea-trips, road-trips, even certain movies and video games. However, the French company Boarding Ring promises that it has its way to solve the problem, as long as the users are willing to wear Boarding Glasses!
Why do many people suffer from motion sickness? It is believed that the brain fails to deal with mixed signals from body parts. For example, when you are looking at your phone on a moving bus, your inner ear realizes the move but your eyes, focused on the screen, think you don't move.
Boarding Glasses tries to ease (减轻)motion sickness by making the user's eyes and ears transmit the same message. After the brain receives the same message, it will think you are in a moving environment Though that sounds difficult, the science behind the glasses is surprisingly simple.
The plastic frames (框架)，made up of two round frames on the front and two on the side, are filled with some blue liquid. Any movement can cause the liquid to flow around the eyes. This allows the eyes to sense the move and send the correct signal to the brain.
According to Antoine Jeannin, CEO of Boarding Ring, Boarding Glasses has been tested. The CEO said that over 95 percent of the users felt better after wearing the glasses. The best part is that Boarding Glasses only has a frame, so a single pair can be worn among a group of friends, or even an entire family!
