“Outer space is a frontier that inspires us and unites us more than anything else,” declared the US Assistant Secretary for Arms Control, Dr. Yleem Poblete. “And as we continue to push further into our own solar system, new businesses will be built to seize the endless possibilities before us.”
However, there are growing concerns about the possibility of intentional acts of aggression in space, warned Dr. Poblete. The United States has raised concerns for many years that Russia is seeking the development and placement of anti-satellite weapons. As recently as February 2017, a Russian Air Force Squadron Commander stated that Russia is developing new missiles with the intention of destroying satellites. Furthermore, we have read statements from the Russian Ministry of Defense that it is working on creating “a mobile attack anti-satellite system”.
Vladimir Putin (Russian President) has alluded to space weapons being more “acceptable in the political and military respect”. This behavior continues despite Russia stating many times that it places a high priority on the promotion of the draft “Treaty on the Prevention of the Placement of Weapons in Outer Space” or PPWT.
The problem with such a treaty, said Dr. Poblete, is that it's difficult to determine an object’s true purpose simply by observing it on orbit. At this time, there are no means of distinguishing many objects' behaviors from that of a weapon, making outer space arms control measures like those in the proposed PPWT impractical.
In short, said Poblete, the proposed PPWT does not reduce the potential for conflict from extending into outer space. Plus, Russia may be engaging in the very behavior it claims to seek to prohibit.
“We must take concrete steps to strengthen the stability and sustainability of space,” declared Dr. Poblete, “The draft PPWT is not the right approach to accomplishing that. It is a questionable document, proposed by a country [Russia] that has routinely violated its international commitments.”

【推荐1】Everyone has a phone in their pocket nowadays, but how often do we really use them for their original purpose—to make a call? Telephone culture is disappearing. What brought us to this moment, and what are its effects?
“No one picks up the phone anymore,” wrote Alex C. Madrigal on The Atlantic. “The reflex (习惯性动作) of answering—built so deeply into people who grew up in 20th-centurytelephonic culture—is gone.”
The shift is of course due in large part to more communication options: Texting with photos, videos, emojis, reaction gifs, links and even voice messages can be a more attractive option.
Texting is light and fun, not nearly as demanding of your attention as a phone call. It can also be done with multiple people at the same time. Social media, email and video calls have also eaten away at traditional phone calls.
In recent years, another reason has caused people to ignore phone calls completely: robocalls. Robocalls are automated messages from organizations verifying (核实) your phone number or telemarketers trying to sell something. Americans received 22.8 billion robocalls halfway through 2020, equaling an annual rate of 45.6 billion, slightly below 2018 numbers, according to You-Mail, a robocall protection service and blocking app.
As telephone culture disappears, what is the loss of a singular family phone doing to the family unit? Early landline phones unified family members, whereas mobile phones isolate (使隔绝) them.
“The shared family phone served as an anchor (给以安全感的物品) for home,” said Luke Fernandez, a Weber State University computer-science professor and co-author of Bored, Lonely, Angry, Stupid: Feelings About Technology, From the Telegraph to Twitter. “With smartphones, we have gained mobility and privacy. But the value of the home has been diminished, as has its capacity to guide and monitor family behavior and perhaps bind families more closely together,” Fernandez said.
Of course, as technology progresses, lives always change for better or for worse. With the loss of telephone culture, families will need to find other ways to unite.

【推荐2】In 2011, British wildlife photographer David Slater traveled to the Tangkoko Nature Reserve on the island of Sulawesi in Indonesia. After following about 25 endangered black monkeys in the forest, Slater set up his camera. The monkeys went up to it, and were attracted by it immediately. Finally, they began playing with the camera and took photos of themselves. One monkey took many photos, some of which appeared with a July 2011 Daily Mail article about Slater playing with the monkeys. One of the photos became the cover of a book of Slater’s work. Wildlife Personalities, which was published in 2014 by Blurb, Inc., in San Francisco. Slater is considered as the copyright (版权) owner of the photos.
In September 2015, however, the People for the Ethical Treatment of Animals (PETA) considered the monkey it calls Naruto as the copyright owner of the photos. Through his “friends” at PETA, Naruto was suing (控诉) the photographer and the publishing company Blurb for copyright: “The photos resulted from the purposeful actions of Naruto and were not helped by Slater, resulting in works of authorship… by Naruto.”
“If a human had taken a photo with Slater’s camera, that person would own the copyright to the photo,” says Jeff Kerr o£ PETA. “Naruto should be treated no differently.”
The lawyer for Slater and Blurb, Andrew Dhuey, required that the case be dismissed (被驳回) in November 2015. Dhuey mentioned a 2004 case in which the court had to decide whether whales could sue the US Navy for the danger they’d received from machines used by the Navy. The court ruled that they could not.
In January, the court ruled in favor of dismissing the case. PETA lawyer Jeff Kerr objected, “We believe it has been stated clearly in the Copyright Act. The Act allows courts to fill in decisions like this one.”

The Yosufs’ house is unlike any other house. In the sitting room, instead of a television, there is a blackboard on the wall. For two hours every day, Mr Yosuf writes complex mathematical problems on the board. His daughter, Zuleika, copies them into an exercise book and solves them.
Zuleika is special. She’s five years old, but instead of watching cartoons or playing computer games, her favourite pastimes are solving equations and reading books. She already spends hours every day in a university library. Next year Zuleika will become Britain’s youngest “A” level student.
Not surprisingly, the Yosufs are a very clever family. Zuleika’s two sisters and a brother, aged 16, 14 and 12 are also good at maths and are already at university. Her father, who specialises in maths research, has taught them all. “Zuleika is very competitive, says her father.” She sees her brother and sisters working every day and she can’t wait to catch up with them. I remember teaching the others maths when they were eight. Zuleika solves the same problems now, although she took up maths much earlier. We could see she was interested in numbers at a much younger age. ”
So what is the secret of their success? When their first child arrived, Mr Yosuf and his wife made up their minds to teach all of their children at home. They say that home tuition combined with love and understanding has helped their children to succeed. “We’ve been patient and supportive, and they take pride in what they do,” says Mr. Yosuf. “Maybe Zuleika has a natural talent for maths, but I believe given the right surroundings, any child could do well. ”
One thing all child prodigies(神童) do have in common is a complete dedication to and love of their subject. They spend many more hours working at it than the average child, and this extra effort is reflected in their achievements. It is not necessary to be extremely talented to be a child prodigy, but you do have to have a lot of motivation.

【推荐1】For this year’s Fourth of July celebration, some US cities have replaced traditional fireworks with impressive drone (无人机) light shows. Maybe most importantly, the drones being employed by more and more cities for Fourdr of July celebrations don’t leave behind a blanket of smoke at a time when America’s air quality is already at its worst in decades.
“Around the world, we’ve seen consistently that, during times when firework usage is really high, we have really bad air quality.” said Pallavi Pant, the head of global health at the Health Effects Institute. And while that pollution typically disappears quickly— usually around noon on July 5th— the concentration can be high enough to worsen the condition for those with breathing problems. Cities making the switch to high-tech shows say there’re plenty of other reasons why people may want to avoid traditional fireworks.
“Fireworks can be harmful to folks who suffer from PTSD (创伤后应激障碍) or families who have dogs. Salt Lake City has more households with dogs than we do with kids,” said Lynze Twede, a manager for Salt Lake City Public Lands. “Being away from fireworks is considered by many to be the tendency of the future. Drones are reusable, while with fireworks, you have smoke, falling debris (碎片), and noise which especially stresses dogs and people with PTSD out.”
About 12, 264 fires were started by firework displays in 2021, according to the National Fire Protection Association. Those added up to around $59 million in direct property damage. But data also shows that much of the wildfire risk comes not from grand public displays, but from the small-scale shows on sidewalks.
It may be too early to tell how this tendency may get close to smaller shows and consumers, but the price is a limiting factor.

【推荐2】Female squash (壁球) player Karthik, who partnered with Sandhu to claim India’s first-ever gold medal in squash mixed doubles on Thursday — defeating traditional powerhouse Malaysia — said she hoped their victory would motivate more young women in her homeland to play the sport.
“It’s unbelievable,” said Karthik, the world champion in mixed doubles and women’s doubles, and the first Indian woman to rank in the world’s top 10. “If you asked us a few years back if we would be part of this team or where we are standing and winning gold, I don’t think we would have believed it. We really put in the effort and the hard work back home, and I’m very glad it worked out.”
Karthik began playing squash at age 10 and competed in her first professional tournament at age 15. She became the first Indian female squash player to win an-individual medal at the Asian Games when she took singles bronze at the 2014 Games in Incheon, Republic of Korea. But she took a break from the sport between 2018 and 2022 to get married. After giving birth to twin sons in 2021, she returned to training later that year and returned to competition at the 2022 World Doubles Championships in Glasgow. She and Saurav then became the first Indian squash players to win a gold medal at the world doubles championships, following their victory in the mixed event at the 2022 edition in Glasgow. Later, she won the women’s doubles title alongside Joshana Chinappa to become the first Indian player to win multiple titles at the tournament.
“Being an athlete is tough, but being an Indian woman athlete is tougher, especially when you compete for the country. But it’s heartening to see so many women taking up sports because of strong role models like (Indian boxer) Mary Kom, (Indian badminton player) PV Sindhu and others.”
The 32-year-old said she believed women athletes are earing more attention in India, partly because of their performances. “I think just a little bit of encouragement for women will go a long way, ” Karthik said. “Hopefully, we can get more opportunities; We hope that women in sports and women in the workplace can receive more attention and recognition whether in sports or in the workplace.”

【推荐3】A powerful earthquake hit Morocco on Friday night, killing over 2,500 people and causing huge damage over a large area. The quake was one of the most powerful ever recorded in Morocco. It’s also the country’s deadliest earthquake in over 60 years. So far, the earthquake is reported to have killed over 2,680 people. It has injured over 2,500 others. The earthquake was especially dangerous because it happened at night, when people were asleep in their homes.
Marrakesh is a big city that’s popular with tourists. Many of its modern buildings seem to have survived the earthquake, but the old part of the city, Medina, was hit hard. It has buildings that are over 1,000 years old. Many of those buildings were demolished.
Outside of Marrakesh, the earthquake caused even more damage. In the Atlas Mountains, the earthquake’s center, there are many small villages, some of which were nearly destroyed.
Many of the people in the area live in simple houses made of mud bricks, which is a traditional way of building in Morocco. But it’s not strong enough to protect against earthquakes. Although the Moroccan government has laws that require buildings to be built more safely, these rules are often ignored.
Rescue workers have been working hard to save those affected by the quake. In larger cities, rescue efforts seem to be going well. But it has taken a lot longer for help to reach remote areas in the mountains. Many of these villages are difficult to get to. The earthquake caused landslides, blocking roads, and making these places even more difficult to reach. In some areas, phone and electrical service were also knocked out, leaving these places completely cut off. That means that the local people in some remote areas have had to deal with the situation on their own. In some areas, people have been digging through the broken stones or bricks with their hands, trying to find survivors. Many people are sleeping outside, unsure if their houses are safe.
Many outside countries have offered to help Morocco. Some countries have offered teams of experts; others have offered supplies.

【推荐1】Researchers discovered a hidden continent on Earth, but it's not Atlantis. They found it while reconstructing the evolution of Mediterranean region's complex geology, which rises with mountain ranges and dips with seas from Spain to Iran.
The continent is called Greater Adria. It's the size of Greenland and it broke off from North Africa, only to be buried under Southern Europe about 140 million years ago. And chances are you've been there without even knowing it. “Forget Atlantis,” said Douwe, study author and professor at Utrecht University. “Without realizing it, vast numbers of tourists spend their holiday each year on the lost continent of Greater Adria.” This area is called Adria by geologists, so the researchers for this study refer to the previously undiscovered continent as Greater Adria.
Most of Greater Adria was underwater, covered by shallow seas, coral reefs and sediments (沉淀物). The sediments formed rocks and those rocks became mountain ranges in these areas： the Alps, the Apennines, the Balkans, Greece and Turkey. The researchers found that Greater Adria started to become its own continent about 240 million years ago.
This isn't the first time a lost continent has been found. In January 2017, researchers announced the discovery of a lost continent left over from the supercontinent Gondwana, which began breaking apart 200 million years ago. The leftover piece, which was covered in lava (岩 浆), is now under Mauritius, an island in the Indian Ocean. And in September 2017, a different research team found the lost continent of Zealandia through ocean drilling in the South Pacific. It’s two-thirds of a mile beneath the sea.
Greater Adria isn’t the first lost continent to be found. But if research in past years shows anything, it likely won’t be the last discovery.

【推荐2】With the infection being brought under control, more and more galleries and museums are reopening. While many museums have been putting exhibitions online, visitors still prefer to enjoy works of art in person. Here are four major art exhibitions that are held offline.
The Palace Museum (Dec. 10—Feb. 15)
The exhibition, Everlasting Splendor which is being held in the Meridian Gate Galleries, marks the 600th anniversary of China’s imperial palace. Over 400 cultural relics are displayed at the exhibition, reflecting the history of the Forbidden City’s construction, the development of its layout, and how it has been protected and restored in the past decades.
The National Museum of China (Jan. 4—Mar. 29)
The exhibition, A Sail Over Miles, offers a brief review of the ancient Silk Road in ceramics (陶瓷). It guides visitors through the manufacturing, export and shipping routes from the Tang Dynasty to the Qing Dynasty with over 300 ceramic relies, including a pot dug from Nanhai No 1, a Chinese cargo ship dating back more than 800 years. The exhibition also shows Japanese, Korean and British ceramics, reflecting the influence of China’s porcelain-making techniques in local industries.
The Capital Museum (Jan. 1—Mar. 30)
The Capital Museum is to host Man of Infinite Refinement: Special Exhibition on the Paintings and Calligraphy of Su Shi, a calligraphy and painting exhibition on the legacy of Su Shi, an iconic figure of ancient Chinese literature and fine arts. The 78 exhibits on display spans from the Northern Song Dynasty through recent history and cover a range of media, including calligraphy, paintings, documents and rarely seen books.
The National Art Museum of China (Nov. 30—Feb. 10)
On show are nearly 300 objects, including paintings, calligraphy works, carved seals, manuscripts, letters and books. Donation of Rong Geng not only reflects his academic accumulation over the years, but forms the basis for his becoming such a well-rounded scholar in the area of Chinese cultural traditions.
Rong Geng (1894—1983), a scholar of Chinese paleography, educator and connoisseur of antiquities, is little known to the general public. However, his extensive studies of ancient Chinese writings and his former collection of archaic oracle bones and bronzes continue to enrich people’s cultural life.

【推荐1】Jupiter, the largest planet in our solar system, is one of the most interesting. It was named after Jupiter, the most important Roman god. Nicknamed “King of Planets”, it is the fifth planet from the Sun and the fourth brightest object in the sky. Before the invention of the telescope, Jupiter was thought to be a bright star.
In 1610, the famous astronomer Galileo realized that Jupiter was a planet and revolved around (围绕……转动) the Sun. He also noticed that it had four large moons. These are known as the Galileo moons. The biggest is Ganymede, and it’s larger than the planet Mercury. Next in size is Calisto, which is the farthest away from Jupiter. Io is the closest to the planet and has many active volcanoes. Europa, the smallest of the Galileo moons, is covered with ice, and scientists believe there may be an ocean underneath.
Galileo said that Jupiter wasn’t a star but a planet. Before his time, people believed that the Sun, stars and other planets all revolved around the Earth. However, Galileo proved that the Sun was at the center of the solar system!
Jupiter is farther out in the solar system than the Earth, so it takes longer to revolve around the Sun. This means that one year on Jupiter as long as 11.6 Earth years. However, a day on Jupiter is much shorter, only 9.8 Earth hours. This is because it spins a lot faster than the Earth does. Another of Jupiter’s interesting features is its “Great Red Spot”. This large red spot on the surface of the planet is a huge storm, like a hurricane but bigger. It covers an area twice as big the Earth and has been going on for at least 400 years!
1. Which of the following is TRUE about Jupiter?| A．It’s the fourth planet from the Sun. |
| B．It’s the brightest object in the sky. |
| C．Either the Earth or Mercury is bigger than it. |
| D．One of its moons might have an ocean underneath. |
| A．Io | B．Europa |
| C．Calisto | D．Ganymede |
| A．Because Jupiter was thought to be smaller than the Earth. |
| B．Because it proved that the Earth isn’t the center of the solar system. |
| C．Because Jupiter was found to be the only planet in the solar system. |

【推荐2】Though it is not good for us to expose ourselves to sunlight for too long, allowing ourselves appropriate amount of exposure to sunlight gives us many benefits and affects us in a number of ways.
Without the sun, life would not have developed. It gives us energy and heats our world. The sun gives us light and thus in turn we are able to see the beautiful colors in our world. It makes us feel good when we feel the warmth of its rays on our shoulders. We store the energy from the sun to help build and heat our houses.
Without sunlight we would not be able to survive. Sunlight gives balance. All living things live in a food chain and at the beginning of the food chain conies the plant which absorbs sunlight and transforms light energy into chemical energy ,which will then be absorbed by another life to be turned into a new kind of energy and so on.
One of the benefits that we can get from sunlight is that we can receive vitamin D from sunlight. It helps us to keep a healthy body, control the amount of minerals in the body, which is needed to help keep our bones and teeth in good condition and helps to keep a well-balanced mind.
Different places on the earth receive varying degrees of sunlight, which will decide the region's climate. For example, the farther away it is from the equator （赤道）,the sharper the angle of the sun's rays that reach it, which means that sunlight coverage will be more spread out, and receive less heat than lower latitude（纬度）areas nearer the equator.
1. Why does sunlight give balance?| A．It helps to pass energy. | B．It helps to absorb energy. |
| C．It helps to form new lives. | D．It helps to protect new lives. |

【推荐3】It has been four years since the Flashfood App was set to hit Canadian grocery stores and make it easier for shoppers to buy soon-to-expiry (保质期) food at a discount. Much to my delight, I heard it advertised recently on a radio station and figured it’s time for an update, especially since people became more aware of food waste’s role in the climate crisis.
The first thing I did was download the App. I hadn’t done it before because it was limited to a few locations, but now it’s all over Canada. I could see immediately that many brands of yogurt are all marked down 50 percent. Users pay for the food using the App, and then pick it up at a marked location in the store. There is no need for you to worry about them actually being bad.
It makes sense for retailers(零售商) to get behind this App because it offers a win-win situation for everyone involved. Flashfood sells 75% of the products made available through its App while saving consumers an average of 50% on those grocery items, and it has 300 000 active users right now. That number is expected to grow naturally as Flashfood partners with more grocers.
“As a food retailer, we are in the business of providing food, not wasting it. The Flashfood program allows us to provide our customers with a convenient and environmentally sustainable (可持续的) way to purchase food. Loblaw sells 77% of the items it puts on Flashfood, moving an average of ＄800 to ＄1000 worth of goods weekly at each of its largest stores,” said Gord Chem, senior VP with Loblaw’s Real Canadian Superstores.
I love looking for discount deals at the grocery store and always keep an eye out for the hot pink clearance stickers. But it’s always random, and I never know what I’m going to get from week to week. The appeal of Flashfood is that I can see what’s available, pre-purchase it, and leave it off my shopping list.
1. What can we know about the food on the Flashfood?| A．It’s delivered directly to the customers. | B．Users can pay for it in the marked store. |
| C．Much of it is charged at half the price. | D．It’ll be a month away before it goes bad. |
