2 . We are in the midst of a battle for our attention. Our devices have affected our brains and destroyed our collective ability to concentrate. Journalist Johann Hair’s new book, Stolen Focus, has just joined the voices complaining about the great influence of the digital age. His and other recent books reflect a public perception that our focus is under attack.
Indeed, in our new research, we found some clear concerns. We surveyed a nationally representative sample of 2,093 UK adults in 2021. Half of those surveyed felt their attention spans were shorter than they used to be, compared with a quarter who didn't. And three quarters of participants agreed we're living through a time when there's non-stop competition for our attention between a variety of media channels and information outlets (渠道).
There has long been a worry about the threat to attention brought by new cultural forms, whether that’s social media or the cheap paperback sensation novels of the 19th century. Even as far back as ancient Greece, the philosopher Socrates complained that the written words created “forgetfulness in our souls”. There has always been a tendency to fear the effects that new media and technologies will have on our minds.
The reality is that we simply don’t have long-term studies that tell us whether our attention spans have actually shrunk. What we do know from our study is that people overestimate some of the problems. There’s no such thing as an average attention span. Our ability to focus varies hugely depending on the individual and the task at hand.
It’s also important not to ignore the many benefits that technology brings to our life. Much of the public surveyed recognized these, so while half thought big tech and social media were ruining young people’s attention spans, roughly another half felt that being easily distracted was more to do with people’s personalities than any negative influence that technology may or may not have. Also, half of the public believed multitasking at work and switching frequently between emails, phone calls, and other tasks can create a more efficient and satisfactory work experience.

7 . Every spring, in regions at high altitudes around the world, one of Earth’s tiniest migrations takes place. The migrants are single-celled green algae (海藻); they are relatives to plants growing in the sea, but instead of living in the sea they live in snow. They spend the winter deep in the snow. In the spring, they wake and swim up through flowing streams of melted snow to the surface, dividing and photosynthesizing (进行光合作用) as they go. Then, at the top, they turn red. This creates what scientists call pink snow.
The color comes from astaxanthin (虾青素), a substance that gives some living things their reddish color. The algae produce astaxanthin as a form of sun protection; it absorbs UV light, thereby warming the organisms and thus melting the surrounding snow. “The melting helps them a lot,” said Roman Dial, a biologist at Alaska Pacific University. “The moment there is liquid water on the snow, the algae start growing.”
Pink snow is a perfectly natural phenomenon, but in an age of disappearing glaciers (冰川), it is also problematic. Last year, scientists discovered that the algae turned the snow surface dark, reducing the amount of sunlight reflected by some glaciers in Scandinavia—and increasing the amount of sunlight absorbed—by 30%. The result, as Dial and his colleagues demonstrated in this month’s issue of Nature Geoscience, is faster melting. As in other parts of the warming planet—particularly the Arctic, where scientists fear that melting permafrost (永冻土层) may lead to further climatic changes. Ice sheets are already being darkened by dust and ash, which makes the process of melting faster and provides nutrients for algae growth. As the organisms multiply, they melt even more snow, which allows them to increase in their population again. “It spreads more rapidly than people realize, once it gets established,” Dial said.
Snow algae need snow; when that’s gone, which seems to be the direction of things, the snow algae will go, too. Before the snow algae disappear, though, and while there’s still some glacier left, it’s entirely possible that the last snow we’ll see on Earth will be pink or even red, a wound on Earth.

8 . A little girl ran to her bedroom and pulled out her piggy bank (储蓄罐) from a secret drawer in her closet. She took the change from it and counted it carefully three times.
She carefully placed the coins in a jar and twisted on the cap. She took the jar and slipped out of the back door. She made her way six blocks to a drug store. She waited patiently for the pharmacist (药剂师) to give her some attention but he was too busy attending other customers at that moment. She tried several times to get his attention but failed. Finally, she took a quarter from her jar and hit it on the glass counter, which was finally able to get her some attention.
“What do you want, little Miss?” the pharmacist asked the tiny girl in the front of his counter. “My brother is really, really sick and I want to buy a miracle,” the girl answered back. “I beg your pardon?” said the pharmacist. “My brother is really sick and my daddy says only a miracle can cure him now. So, I want to get a miracle for him. How much does it cost?” “I’m sorry but I can’t help you. We don’t sell miracles here, little girl,” the pharmacist said, softening a little.
Next to the little girl was a tall well-dressed man. He lowered himself and asked the little girl, “What kind of a miracle does your brother need?” “I don’t know,” the girl replied with her eyes in tears. “I just know he is very sick and has something bad growing inside his head. Doctor says he needs an operation. But daddy can’t afford it, so we need a miracle to save him now. I can use all my money to save my brother.” “How much do you have?” asked the man. “One dollar and twelve cents, it’s all the money I have now, but I can get some more if needed,” the girl answered in a whisper. “Well, what a coincidence,” smiled the man. “That is the exact price of a miracle for a little brother. Take me to your brother. Let’s see if I have the miracle your brother needs.”
The man was a famous nuerosurgeon (神经外科医生). He was just the right person needed to save the little boy’s life. The operation was completed without any charges and it went successfully.
Her mommy wondered how much it would have cost. The little girl just smiled, but said nothing.

9 . Welcome to the library, new students! The library will play a big part in your experience while you’re at the University of York. There’s a lot to take in if you’re new.
Buildings
We have several library sites, including a main library on Campus West and two other libraries in the City Centre. Our main library is made up of three connected buildings: the Morrell, the Fairhurst and the Burton. You enter all three buildings through the Morrell.
Resources
Our library has lots of books and journal articles that will help with your studies and research. We also provide videos, slides and interactive tutorials (学习指南) to help you develop your information skills, learn to code (编码), work with data and get creative with digital technologies. We’ll show you how to follow good academic practice and develop your digital skills for effective reading, note-making, essay writing and problem solving.
Checking out
Always bring Library Card with you as you will need it to enter the library and borrow items. You can borrow books and access the electronic resources provided by the library for free. There’s no need to request books that are available. This means you will need to go to the shelves yourself to find the books you need. You can borrow up to 75 items at once, and you’ll need to check your emails to find out when to bring them back.
