2 . International Women's Day is March 8. The first celebration was held in 1911, and the event was recognized by the United Nations starting in 1975.
It's a great time to think about the origin of the word "woman". Some people think the word “woman" is a compound(混合)of the words“womb”and“man". Not so. Rather,it's a compound of "wife" and "man", a combination that can be traced back to Old English. You see, when Old English was first being spoken in the 5th century AD, there were two distinct words for men and women: "wer" meant "adult male",and "wif” meant “adult female". There was a third word,“man", which simply meant "person"or "human being”. These words could be combined:“wer" plus“man"(in the form of "waepman")meant "adult male person" and“wif” plus"man”("wilman") meant “adult female person”.
Those middle forms,“wimnan"and "wommon"with the two M's in the middle, remind me of Noah Webster's efforts to simplify English spelling by suggesting changing the spelling "woman” to“wimmen" to have the spelling better match the pronunciation. He put that in his 1806 Compendious Dictionary o f the English Language, but it didn't become popular.
And the Old English word for "adult male" evolved into a simplified form. The compound word "weapman" melted into the simple word we use today: "man".
Maybe the lesson to take from all this is that the role of women in society has always been complex. Whatever the case, the word "woman" today was originally a compound of the Old English words for"woman” and “human being”.

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 . 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.

5 . 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.

10 . In school, we' re taught word repetition is bad and that we shouldn't use the same word over and over again in the same piece. It gives the impression that we have a severely limited vocabulary.
Later on, however, we' re sometimes told that it's better to use the same word repeatedly. With dialogue, some novel-writing professors recommend using "said" with each comment instead of replacing it with synonyms(同义词)(whispered, responded, etc.). Word repetition is also an emotional appeal strategy for speeches and sales, because people remember and respond to things they hear multiple times.
So which way is right?
The answer is, "It depends.” If you're writing for school, it's not a very good idea to use the same word constantly. If you're writing dialogue that you want to keep moving at a fast pace, using mostly “said” can help do that because "he said” and "she said” more or less fade into the background. They don't take much time or attention for the readers, so they can skip over and focus on the dialogue. However, this isn't a hard-and-fast rule. You might rely on “said” for one scene and mix in a bunch of synonyms for another.
Repeating a word can also provide emphasis, and it's really good for sales. Think about commercials and how they re-use specific words to make sure that those words stick in your memories. The trick to this method, however, is that you have to make sure other words aren't repeating the same way. Otherwise, the repetition loses its power.
In the end, it comes down to personal taste and the effect you' re trying to achieve. As Shakespeare said, "there is nothing either good or bad, but thinking makes it so." You may need to repeat the same word every time. You may need to mix it up with synonyms. You may need to do both at the same time for different ideas. And the decision may change completely by what you're trying to do.
