21、At the beginning of 2020, I began a Buy Nothing New challenge, which meant everything I purchased (购买) had to be second-hand. The challenge went well for the first two months, but then came to an abrupt end in March, with the rise of COVID-19 and closures of all unnecessary stores in my neighborhood.
I found myself facing a difficult choice. I could buy second-hand items (物品) on the Internet or buy directly from local businesses that may have had to close down their storefronts, due to social distancing rules, but still had full shelves behind closed doors. I preferred the latter, as it meant my money would go straight into the hands of neighbors who need it more than ever now.
That is how I began my “slow shopping for the modem age”. Over the few weeks, I have made a few necessary purchases. One was for my son’s birthday. I sent a Facebook message to the local toy store to ask about a toy I was looking for. The owner responded immediately with pictures of various choices. After several exchanges, we settled on a dinosaur coloring kit. I e-transferred (电子转账) the money and he dropped it off at my back door the following morning.
That has been an interesting lesson for me. First, it underscores the power of the Internet for shopping locally. If it weren’t for the Internet, I wouldn’t know how to contact these businesses because they’re not answering phones as usual. Second, the local supply chain is more reliable and I received the items much faster than if I’d ordered them online. Third, because I have to find some specific items, it forces me to think long and hard about what I actually need. Finally, I realize that if it’s possible to support local businesses at a time like this, it’s possible to support them anytime.
I challenge readers to try to provide for their needs by sourcing items from their own neighborhoods. All it takes is a message or a phone call, and those items could be on your doorstep within hours. Give it a try; it’s deeply satisfying.

22、Today，there are thousands of national parks all over the world.【1】 In that year，the United States government gave a large piece of land to the state of California.They ask the state to create a special park to protect the mountains and forest in the area.The trees in this area are called sequoias.【2】 They are the tallest living things in the world and are not found anywhere else on Earth.
Conservationists in other countries saw what happened in California and soon began to do the same.Today Europe has over 350 national parks.The first one in France，Vanoise National Park，was created in 1963 because the government wanted to stop a plan to build a large tourist project there.The idea of creating a national park was first discussed in the 1940s，but people couldn’t agree on what size to make the park.【3】 Ecologists worked with the government to finally agree on a plan that protected the animals，while still allowing some tourism.
【4】Like the first California park，the Bavarian Forest National Park was created to protect mountains and trees.It is the largest area of protected forest in Europe.The park has shelters where visitors can spend a night close to nature.In some places high up in the mountains，there are steps cut into the rock.【5】 Thousands of tourists go to the park each year.They walk through the attractive woods and enjoy the wonderful mountain views.
A．This makes it easier for tourists to get to the top.
B．The world’s first national park was started in 1864.
C．The biggest ones are over one hundred meters high.
D．The first national park in Germany opened in 1970.
E．The Giant Forest in Sequoia National Park is alive with mystery and wonder.
F．They also had different ideas on whether to put human or animal needs first.

23、One night many years ago when I was on the bridge of a ship that passed one of our large cities on a quiet night, I saw its lights reflected in the sky and heard the rumblings of the city's noises. As I looked to my other side, I could see nothing but open space of darkness and endless water. I realized how small I was and that my own problems of life did not seem great.
I have spent twenty—five years on boats. Now I am a docking pilot. My job is to bring in the large luxury liners and stay with them until they are safely anchored in their berths. Sometimes this requires two tugs(拖船）, sometimes many more, depending on the tide, the weather, and the draft of the vessel.
Most of you no doubt have seen these tugs pushing and pulling at the big liners. What they are doing doesn't seem to make much sense at first, but presently the big boat is alongside her landing stage, her ropes made fast, and the job is done.
These tugs, whether one or ten, move about in accord with whistle signals I send them from the bridge of the big liner. These signals make up a language that is just as dependable as the spoken word; or even more so, because our docking signals are rarely misunderstood. The captain of each tug does his work according to the signals he receives. He never asks questions. He takes everything on faith, and it always works out.
I fell very important the first time I ever docked a big liner, thinking that I was in control of a great ship worth millions of dollars and the owners were depending on me to bring her safely to her berth. After I had docked several of the large liners, I realized I was not important, but simply the quarterback who called the signals.
Working around tugboats has had its effect on what I believe. The great transatlantic liners depend on the help of the little tugs to bring them safely to port, and it is with one's success.

24、 Printed circuit boards are vital components of modern electronics. However, once they have served their purpose, they are often burned or buried in landfills, polluting the air, soil and water. Most concerning are the flame retardants （阻燃剂）added to printed circuit boards to keep them from catching fire. Now, researchers reporting in ACS Sustainable Chemistry & Engineering have developed a ball-milling method to break down these potentially harmful compounds enabling safer disposal （处理）.
Composed of 30% metallic and 70% nonmetallic particles, printed circuit boards support and connect all of the electrical components of a device. Metallic components can be recovered from circuit boards easily using traditional methods leaving behind nonmetallic particles including those flame retardants and other additives. Scientists have found that compounds in those flame retardants can do harm to people's health, especially to those women who are pregnant. Therefore researchers have been wanting to develop a new method to remove the flame retardants from waste printed circuit boards so that they wouldn't do harm to people and the environment.
The researchers broke down printed circuit boards and removed the metallic components. Then，they put the nonmetallic particles into a ball mill — a rotating （旋转的）machine that uses hard stone balls to make materials into very small pieces. They also added iron powder, which prior studies had shown was helpful for removing chemicals from organic compounds. After ball-milling, the harmful chemicals on the surface of the particles had decreased by 50%・ The researchers determined that during the ball-milling process, iron transferred electrons to flame retardant compounds causing the internal structure to stretch and break.
The authors acknowledge funding from the 111 Project, the Natural Science Foundation of Guangdong Province, China and the Pearl River Star of Science and Technology.

D.The ball-milling method is promising.
25、For most birds, eyes are essential to life on the fly. _________ when studying how birds might adapt to our quickly changing world, ornithologists (鸟类学家) have largely overlooked eye size in favor of traits such as wing length and beak shape. Now, though, a lost “treasure trove” (宝库) of avian (鸟的) eyeball measurements offers a new view.
In 1982 University of Chicago graduate student Stanley Ritland carefully _________ the eyeballs of nearly 2,800 species. He never published his data, but Ian Ausprey, a graduate student at University of Florida, has just given it a second look. His analysis _________ previous work in Peru showing that smaller-eyed birds adapt better to changing habitats.
“We’re able to show strong correlations between eye size, the type of _________ the birds use, as well as their food-searching behavior,” Ausprey says. Ritland’s measurements indicated an inverse relation between eye and _________ size. Birds with smaller eyes tended to be _________, traveling across many habitats; larger-eyed species had _________ ranges, concentrated around the equator (赤道) and often covered by dense forest shade. The study suggests that smaller-eyed birds can _________ handle varying light levels as they travel, whereas larger-eyed birds struggle with bright light outside of their dim woodlands.
Ausprey had already seen this _________ in Peru’s mountainous cloud forests. In these biodiversity hotspots, he says, “eye size is __________ related to how birds respond to agricultural disturbance.” Larger-eyed birds tend to __________ from brightly-lit agricultural and deforested landscapes; smaller-eyed birds adapt. The new study __________ Ausprey’s Peru observations to a wider variety of birds elsewhere, including parrots and woodpeckers.
Allison Shultz, an ornithologist involved in the research, praises it for highlighting the importance of birds’ light __________. Her own work has found a link between bird coloration and environmental light, and she looks forward to future research exploring how light pollution and deforestation might further shape bird eyes. “I’d be very curious if we’re actually seeing eyes __________ to better match newer light environments,” Shultz adds.
Ausprey says the study underscores the importance of __________ habitats across the light-availability spectrum (光谱), especially areas of dense rain forests, to protect birds with eyes of all sizes from habitat loss.
