Plogging — A Win-Win Activity
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Zu Ti of the Jin Dynasty was a man who had with great ambition. When he was young, he had a good friend
One day, when they were sleeping. Zu Ti heard the rooster crowing (鸡鸣) . He woke up Liu Kun and said, “How about
The idiom “to rise with the rooster” teaches us that with ambition and hard work,
I still remember how nervous I felt doing some things for the first time. You’d think that after a lot of first times the butterflies-in-stomach feeling would disappear. But here’s what happened a month ago.
“Please come to the chess club tomorrow,” Mareya said to me. “I know you’re going to love it!” “I’ve never even played chess(国际象棋),” I said. “It seems super hard.”
“I went last week, and it was extremely fun!” said Mareya. “Really?” I said, not convinced.
“Really. Also, the club needs more people to keep it going.” Mareya smiled.
“Listen. If you try it, I’ll do my silly rabbit dance in the middle of recess (课间休息).” I laughed. “In front of everyone? It’s a deal!”
When I arrived at home. I searched our game shelves. Finally, at the very bottom of the pile, I found a tattered (破旧的) box with a chessboard and plastic chess pieces. I read the instructions carefully. Knights, rooks, bishops, pawns, a king, and a queen — each piece had a special starting place and its own way of moving. My heart sank. I couldn’t possibly memorize all the rules in time. Everyone in the chess club was going to think I was inexperienced!
That night, I dreamed I was in a chess game, and the queens, kings, and knights were laughing at me. Even the knights’ horses were snickering (窃笑)! The next day, I told Mareya I was having second thoughts.
“Please don’t back out,” she said. “Remember our deal.”
“I would like to see your silly rabbit dance,” I said, smiling.
After school, I found the chess club’s meeting room and went inside. I looked around, but Mareya was nowhere in sight! To make matters worse, I didn’t know a single person in the room. Butterflies filled my stomach as I started to head toward the door.
“Hi!” said a friendly woman. “I’m Ms.Martinez.”
“I’m Arizona,” I said. “ I was supposed to meet a friend, but I don’t see her. I’d better get going.” “Well, as long as you ‘re here, why don’t you sit with Joe and Jess and watch their game?”

4 . Some Ohio high school students have become winners in a national contest (竞赛) after inventing a mobile phone app that helps needy families find local food pantries (公益食品仓库).
And someday the teens, who are students at Ross High School in Ross Township, may be selling the app to food pantries and food banks across America.
The app was created as part of a computer science class — coordinated (协调) by Butler Tech career school system at the high school. Three students, Jacob Kahmann, Gunner Nonnamaker and Kyle Inderhees, recently were visited by Congressman Warren Davidson, who praised their work. Davidson lauded the teens for creating “this app to set the standard for efficient food collection and distribution (分发)”.
Butler Tech IT Instructor Tom O’Neill said the students’ app includes characteristics that help users locate the nearest food pantry and improve food collection processes, and that the national contest provides a real-life learning chance for his students.
The students are continuing to make additions to the app and are working on turning it into a product, said O’Neill, who in recent years has helped many Ross High School teens win national honors for their computer-science-based inventions.
“The teachers and students in the Ross School District continue to amaze me with their future-thinking and creation,” said Superintendent Scott Gates. “Our students are not only thinking about careers, they are thinking about problems they want to change, solve or improve. The app that was created will make serving a population in need more efficient.”

5 . Tourists visiting La Gomera and EI Hierro in the Canary-Islands can often hear locals communicating over long distances by whistling-not a tune, but the Spanish language. The locals are communicating in Silbo, a whistled Spanish language.
Whistled languages are almost developed in rough, mountainous regions or in thick forest. That’s because whistled speech carries much farther than ordinary speech or shouting. As a result, whistled speech can be understood up to 10 times as far away as ordinary shouting. That lets people communicate even when they cannot easily approach close enough to shout. On La Gomera, for example, a few traditional shepherds (牧羊人) still whistle to one another across mountain valleys that could take hours to cross.
Whistled languages work because many of the key elements of speech can be produced in a whistle, says Meyer. We distinguish(区分) one speech sound from another by small differences in their sound frequency patterns. A long e, for example, is formed higher in the mouth than along o, giving it a higher sound.
To language scientists, such languages are more than just a curiosity. By studying whistled languages, they hope to learn more about how our brains get meaning from the complex sound patterns of speech. Whistling may even provide a chance to know one of the most dramatic jump forward in human evolution(进化): the origin of language itself.
Despite their interest to both language experts and casual observers, whistled languages are disappearing rapidly all over the world, and some, such as the whistled form of the Tepehua language in Mexico, have already disappeared. “...now you still find whistled speech only in places that are very, very remote, that have had less contact with modernity and less access to roads,” Meyer says.
Fortunately, there is still hope. UNESCO, the UN cultural organization, has listed two whistled languages, Silbo, and a whistled Turkish, as the world’s cultural heritage. Such attention can lead to conservation efforts.

7 . Tea originated in China over two thousand years ago. Today, the country owns over 2,000 varieties of tea, differing in taste, sweet and purpose. Some teas, such as Huang Shan, refresh the sense of taste with their special flavor, while others, such as spicy chai, are added with spices (香料) .
China first started exporting tea during the Ming dynasty (1368—1644), and the drink has since come to lead humanity’s drinking habits far beyond Asia. It is the most widely consumed drink on Earth today, aside from water and coffee.
In Chinese mythology, tea was first discovered by Chinese Emperor Shennong (“Divine Farmer”) in 737BC， when a soft wind carried some leaves into a pot of boiling water. However, the oldest dependable evidence comes from ancient plant remains found in 2016 in Xi’an and western Tibet, showing that tea was grown at least 2,100 years ago during the Western Handy nasty when it was most likely used as medicine.
Generation after generation of tea makers experimented with different brewing (冲泡) techniques, leaves, and ceremonies, resulting in today’s tea culture full of life. There’s no doubt that China’s tea culture has become one of the most popular, diverse, and unique traditions in the world.
China is already the world’s largest tea exporter. The inclusion of the country’s traditional tea-making process on the UNESCO list will obviously generate practical benefits for tea makers in the country and across the world as more resources are given to protect and preserve such millennia-old tea culture and technical practices. As additional attention is brought to this traditional technique, the Chinese tea sector will further tap its potential and improve its growth.
As one of China’s oldest cultural practices, traditional tea processing techniques show the spirit of modesty (谦逊), peace, and comity (礼让). No matter your preference for green or dark tea, with milk or without, Chinese tea isn’t just brews. Instead, it is a bridge connecting different cultures and peoples.
1. What does the first paragraph mainly tell us?| A．Chinese tea has a fresh taste. | B．Chinese tea is added with spices. |
| C．Chinese tea has a long history. | D．Chinese tea has a rich variety. |

8 . There are some famous wetland parks and nature reserves in China.
Zhalong National Nature Reserve
Home to more than one fifth of the world’s red-crowned cranes(鹤), Zhalong National Nature Reserve boasts the most complete, primitive and open wetland ecosystem in northern China. Covering an area of 210, 000 hectares, it has the world’s largest wetland habitat for reeds(芦苇) and was listed as a Wetland of International Importance in 1992.In addition to being a shelter for endangered cranes, the reserve plays a must role in protecting the Songnen Plain ecosystem in northeastern China.
Poyang Lake National Wetland Park
Poyang Lake National Wetland Park is the largest of its kind in Asia and has the most abundant variety of wetland species on the continent. Natural wetlands cover nearly 94% of the park, which has an area of 36, 285 hectares. Approximately 98% of all the world’s Siberian white cranes, which only number around 4, 000, spend the winter on the Po yang Lake.
Lhalu Wetland National Nature Reserve
Named Lhasa’s “oxygen bar”, Lhalu Wetland National Nature Reserve features an alpine wetland ecosystem and serves as an ideal habitat for wet meadows(草甸) as well as several national first-and second-class protected waterbirds. With an average height of 3, 645 metres above sea level, the reserve is China’s highest and largest urban natural wetland. The area is of great importance in regulating the local climate, increasing humidity(湿度) and improving the urban environment of Lhasa.
Dongzhaigang National Nature Reserve
Dongzhaigang is the first wetland nature reserve in China mainly featuring mangrove(红树林) forests. With nearly 97% of domestic mangrove species found here, it boasts the most abundant mangrove resources and tree species among the country’s nature reserves. Dongzhaigang National Nature Reserve is also home to 204 varieties of migratory waterbirds, 119 species of fish and 115 other kinds of huge animals.

9 . Scientists recently discovered that our brains may be just as busy at night as they are during the day. While we sleep, our brains are doing much more than getting ready for the next day. Scientists found that the brain may be busy cleaning out harmful waste materials.
As with many studies, scientists turned to mice for help. They studied the mice brains as they slept and when they were awake. They saw that the brains of sleeping mice were hard at work.
Dr. Maiken led the study. The brain expert says our brains perform two very different jobs. It seems they have daytime jobs. Later they “moonlight” at a nighttime job. And this study says that is what our brains seem to be doing. “When we are awake, the brain cells are working very hard at processing all the information around us. When we are asleep, they work very, very hard at removing all the waste that builds up when we are awake.” The scientists say that the waste material includes poisons.
They also found that during sleep, the brain’s cells become smaller, which allows waste to be removed more successfully. Dr. Maiken says these poisons end up in the liver(肝脏). There, they are broken down and then removed from the body. “So we need to sleep because we have a cleaning system that removes many of the poisonous waste products from the brain.”
Dr. Maiken says the next step is to look for the process in human brains. She says the results show how important sleep is to health and fighting disease. The research may also one day lead to treatments to prevent or help fight mental disorders(精神疾病).
1. According to the scientists, when we sleep, our brains .| A．clean themselves | B．turn off for the night |
| C．process information | D．store energy for the next day |
| A．you work in the moonlight | B．you work hard |
| C．you work only at night | D．you have an extra job |
| A．breaking it down | B．sending it to the liver |
| C．building it up in order | D．removing it from the body |
| A．Opposed. | B．Indifferent. | C．Supportive. | D．Critical. |
10 . NASA made a small experiment to produce oxygen on Mars. Now it has managed to produce about 100 minutes’ worth of breathable oxygen. Now it has a plan to produce much more to support future human exploration.
The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) is a small oxygen- producing equipment that landed on the Red Planet with the Perseverance rover (探测器)in February 2021. Over the 7 hour-long production, MOXIE was able to produce about 15 minutes of oxygen per hour in a variety of difficult conditions. That added up to a total of 50 grams of oxygen ——about 100 minutes’ worth of breathable oxygen for a single astronaut.
“This is a great success,” says Michael Hecht at the Haystack Observatory of the Massachusetts Institute of Technology, who co-leads the MOXIE experiment. Day or night, at different extreme temperatures and in the dust storm, Hecht says that MOXIE continued producing breathable oxygen. The NASA team is now looking to make a more powerful MOXIE, which will not only provide enough life support for an astronaut, but also enough oxygen for a return rocket to Earth.
MOXIE takes in carbon dioxide from the Martian atmosphere and raises the temperature to 800℃ with its heaters. It then pulls out the oxygen atoms(原子) from the carbon dioxide. However, there will be some challenges in the next step. These challenges include being able to prevent the equipment from breaking due to its temperature. Besides, an oxygen device that can support a human needs to work continuously for about 400 days, and so far MOXIE’s work has only lasted for an hour each. “That’s a lot of hours to put on the hardware, regardless of what the technology is,” Hecht says.
However, MOXIE’s first year of success has been a big step forward in showing the technology’s bright future, says Hecht. NASA is now testing new hardware.
1. Over the 7 hour-long production, how much oxygen was produced by MOXIE?| A．50 grams. | B．15 grams. | C．100 grams. | D．7 grams. |
| A．MOXIE went through some tough conditions on Mars. |
| B．It’s a big challenge for MOXIE to work at night. |
| C．All the astronauts were supported by MOXIE. |
| D．MOXIE has provided enough oxygen for a return rocket. |
