1 . Important Things to Know When Dining Out
Cultural dining etiquette (礼节) might surprise you with some of its important rules.
The way you handle chopsticks is important to avoid annoying your companions. When you put them down between bites, always put them down together so they are parallel with the edge of the table in front of you.
In India and the Middle East, it’s considered very rude to eat with your left hand. People in France expect you to eat with a utensil in each hand.
Some of these cultural dining etiquette rules may seem random and strange, but they are important in various countries.
| A．The more friends you make in your lifetime |
| B．The more time you spend in any given country |
| C．Mexicans consider it inappropriate to eat with utensils |
| D．Don’t get caught making an embarrassing mistake at a restaurant |
| E．It’s a good sign for the chef if you make a mess around your plate |
| F．Never stick them upright in your food or cross them as you use them |
| G．It may seem like a simple request to ask for salt and pepper at a meal |

3 . The Best National Parks to Visit in Winter
While most parks tend to draw families in the summer and fall, there are also ideal spots for adventurous winter trips.
Yellowstone National Park, Wyoming
The country’s oldest and best-known national park takes on an almost otherworldly atmosphere in winter: the air filled with rolling steam, the strong colors of hot springs, the surrounding white landscapes, let alone the impressive wildlife during this time, like bison, wolves, and playful red foxes. Just book a guided hiking tour to get a ranger’s perspective on the park and local people.
Joshua Tree National Park, California
With its giant red rocks and unique trees, you’ll feel like stepping onto a foreign planet as you spend hours hiking the Panorama Loop or Maze Loop. The park is recognized as an International Dark Sky Park, featuring virtually zero light pollution and the country’s best views of a starry sky.
Grand Canyon National Park, Arizona
A significantly lower number of visitors in winter means you can take in unblocked views of the South Rim, and get to see the rare beauty of the Grand Canyon dusted with snow. For those adventurous and daring, it is recommended to hike the Bright Angel Trail and take the chance to see the canyon’s wintertime wildlife, including mule deer, elk, and bald eagles.
Virgin Islands National Park, St. John
Surprise! Not all wintertime national park trips need to involve snow. Virgin Islands National Park is most famous for its white-sand beaches. You can also hike inland to visit old sugar plantations, or venture out to the water to swim along with sea turtles and manta rays. You will definitely enjoy a different winter here.

4 . It was a February afternoon in a Brooklyn classroom. Sixteen-year-old Taylor Engler came face to face with a cow. But it was all in her head. She was transported by a virtual reality (VR) headphone. It took the Berkeley Carroll School junior and eight other classmates to a northern New York farm. The farm was 250 miles away. For students, the technology means field trips are no longer kept within the length of a bus ride.
It's unknown how many classrooms have or will use the technology, but experts say few classrooms do or will do. Headphones that require a user's phone can cost as little as $20 or $30, but systems and software for classes run into thousands of dollars. The problem of not having good software is disappearing as more companies enter the market. But the rules for use haven't kept abreast of the development of the technology. In New York, for example, virtual reality lab experiments are not included in the state's hands-on lab time requirements.
Experts say science classes are where virtual reality holds promise for classrooms. “The biggest problem, I think, is going to be how closely it mimics the real world." That's according to David Evans, the director of the National Science Teachers Union. However, he said, “The ability to do dangerous things and to run many, many more cases in a virtual space as opposed to the real physical space stands for a huge learning chance.”
Lamb taught chemistry and he agreed. “Too often in schools, when you do experiments in labs, you mix these together, you mix those together and you get this result. And if you don't get that result, you have done something wrong. But we don't have enough resources for you to redo it, “he said. “In virtual reality, all I do is hit reset on the computer. I don't have to actually use chemicals.”

5 . Winter can usually kill most wildfires. But in the far North，some forest fires just don’t die. They are thought of as “zombie (僵尸) fires”.
“Zombie fires” usually sleep underground in winter. Covered by snow, they smoke through the cold. Fueled by carbon-rich peat (泥炭) and soil in the North, most of these hidden fires spread slowly for less than 500 meters during the winter. When spring comes, the flames (火焰) of the fires appear near sites that they burned in winter, and they turn to burning fresh fuels around. This may happen well before the traditional fire season in the far North.
“Zombie fires” had been known mostly from firefighters’ stories. Few scientists studied them until details in some satellite images attracted one research team. Rebecca Scholten, a member of the team, studies earth systems at Vrije University Amsterdam in the Netherlands. Her team noticed an unusual thing. “New fires have been starting very close to the former years’ fires in recent years，and we wonder how often the fires might survive the winter,” Scholten explains.
These “zombie fires” are rarely seen before, according to a new study from Nature. But in recent years, they are becoming more common, the study warns. It is believed that the “zombie fires” are even on the road of being a threat. Forests in the far North are warming faster than the globe’s average (平均数). Scholten says, “We’re seeing more hot summers and more large fires and strong burning. That could set the stage for the fires to become a bigger problem,” she worries. And the region’s soils hold a lot of carbon—maybe twice as much as earth’s atmosphere. More fires here could give off huge amounts of greenhouse gases. That would drive a cycle of more warming and even higher risk of fires.

7 . Paper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two significant ways. First, the making of paper requires the loss of millions of trees each year. Between 2001 and 2019, the world lost 386 million hectares of forest. Of the trees that were cut down, 42% went to paper production. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot sustain such a high rate of forest loss.
The second great problem with paper is what happens once it is no longer useful. A huge quantity of wastepaper ends up in dumps and landfills (垃圾填埋场), where it can produce harmful gases. Paper in landfills leads to the release (释放) of methane, a gas that is a significant contributor in global warming.
One simple solution can greatly reduce both of these problems: paper recycling. Paper is mainly made from cellulose (纤维素), which makes up the cell walls of trees and many other plants. Because of its structure, cellulose can be used repeatedly in papermaking. So far, trees are the only source of cellulose that can fill the massive demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees.
Thanks to advances in processing, recycled paper isn’t the dull-colored stuff many of us are familiar with any more. It now can offer the same print performance as non-recycled paper.
Effective recycling requires a consistent effort. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be carried out. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industries to do the same.

8 . When asked what his father did for a living, Mike explained to his kindergarten teacher that “he steals things, but it’s OK, because he gets paid to do it. ”
He isn’t wrong. His father is a hacker(黑客), who is proud of his job, just like doctors are proud of the work they do. Thanks to security researchers’ hacking practices, leaks in a new version of the most common Wi-Fi code standard(WPA3)were found before criminals could use them to break into home and business networks. In another case, criminals found an unknown weakness in Google’s Android operating systems before security researchers did, giving the bad guys full control of more than a dozen phone models.
However, finding Mike’s father’s personalized plates for his car with the word ‘HACKING’, an employee of the Texas Department of Motor Vehicles quickly took them away, claiming that a license plate displaying “HACKING” publicized criminal activity. While this reaction really isn’t the fault of the well-intentioned employee, it’s a sign of how a deeply rooted misrepresentation of his profession has created a fixed wrong image. It seems that the way that hackers are described in Hollywood has contributed to the word ‘hacker’ paralleling ‘criminal’, where hackers are often referred to as figures in dark rooms engaged in illegal activity while tapping at keyboards.
But actually, hacking is just an activity. What separates any activity from a crime is, very often, permission. People are free to drive, but they do not have permission to drive 150 miles per hour, which is a criminal offense. Since a driver is just a driver, why must a hacker be a criminal? Someone who engages in the illegal use of hacking should not be called a ‘bad hacker’ but a ‘cybercriminal’. Contrary to popular belief, most hackers like Mike’s father undoubtedly play an important role in keeping companies and people safe.
1. What did Mike’s son think of Mike’s job?| A．Admirable. | B．Amazing. | C．Acceptable. | D．Annoying. |
| A．Its weakness. | B．Its importance. | C．Its variety | D．Its security. |
| A．To entertain the renders. | B．To question the employee’s claim. |
| C．To clarify the concept of hacking. | D．To trace the wrong image of hackers. |
| A．Hacking mostly counts. | B．Hacking is actually a crime. |
| C．Hacking is popular with people. | D．Hacking needs licenses. |
