1 . Some of the oldest living things on our remarkable planet are trees. The record holders are bristlecone pines (狐尾松) of the western United States, quite a few of which are known to be more than 3,000 years old. One individual, discovered in 2012, is estimated to be more than 5,060 years old, making it the oldest known non-clonal tree in the world!
So, how do trees survive for thousands of years?
The other part of the answer has to do with how trees age. In fact, there is quite a debate about whether ancient trees can be considered “immortal (永生的)”. That is, will such trees ever die if they are not killed by an outside force? We may never know the answer to that, but, at the very least,
Older trees benefit greatly from having bodies made mostly of dead woody tissue. In fact, an old tree might be as much as 95 percent dead tissue! Given that it isn’t alive, wood does not require metabolic (新陈代谢的) activity to maintain it,
| A．so an old tree doesn’t really need to do much to keep living |
| B．This is a question that has something to do with the good luck of trees |
| C．However, bristlecones are certainly not alone in terms of the oldest creatures |
| D．This is a fascinating question for biologists that does not yet have a settled answer |
| E．What’s more, some ancient trees have superior chemical defenses against pests and diseases |
| F．which means that trees can survive everywhere without being limited by external and internal conditions |
| G．we know that ancient trees age in ways that are dramatically different from the ways that most animals and even other plants age |
2 . Lying in the Mexican state of Oaxaca, the fishing village Huatulco is home to nine bays, 36 beaches and thousands of baby turtles that apparently needed me. I had three open days on my calendar, and a desire to save some turtles. And so, away I went to Huatulco with Wildcoast, a group of champions-for-change who were protecting coastal and marine ecosystem in the U. S. and Mexico.
I was taken to La Escobilla to experience Wildcoast in action. Just one hour north of Huatulco, this protected beach is where mass turtle nesting happens. This natural phenomenon lasts just four days during rainy season, hundreds of thousands of female sea turtles swinging their way ashore to lay their eggs.
Between threats of dogs, crabs, development and oil spills, the little creatures have the whole world against them. As recently as 2002, turtles hunting was not only a common practice, but an important part of the culture and diet in the Oaxaca communities. Luckily, Wildcoast rescues turtle eggs and recreates habitats by monitoring temperatures and humidity. Thanks to their efforts, the sea turtles have made a major comeback, with now over 72 million turtles being born on the beaches that Wildcoast protects.
I got to hold 50 of the tiny creatures in a bowl. Despite an average laying of 100 eggs, just one in 1, 000 baby turtles will make it to adulthood. Gazing into the bowl, I so badly wanted them to taste the sea and find shelter somewhere deep in the ocean. Finally, it was time to liberate those little creatures. Out spilled the creatures, some moving full steam ahead while others barely paddled in place. Literally, hundreds of them began to spread out across the beach.
With each set of waves, we witnessed the survival of the fittest, some pushing past the whitewash while others crashed back to shore. Their fight for life made my eyes wet. A flock of birds were ready to dive into the sea for their moving targets. “One in 1, 000.” Nature was cruel and compassionate at the same time. After 30 long minutes, the last creature made his way to the sea.

| A．Think twice before you leap. | B．God helps those who help themselves. |
| C．Cease to struggle and you cease to live. | D．When the buying stops, the killing can too. |
3 . The behavior of beavers and other animals has often inspired expressions in English. If someone is very industrious or hard-working in tackling many things at once, we can say the person is “as busy as a beaver.” This phrase hints at one of the characteristics of these wild animals—they are indeed active creatures.
With their large teeth, which are orange due to iron in the tooth enamel (牙齿的珐琅质), beavers can cut down trees and change their environments like no other animals except humans. They use these fallen trees to build dams, creating safe, watery environments. The busy beavers build homes — called lodges — in the ponds created by the dams. The only way to get in and out of lodges is by entering an underwater opening of the structures. This offers beavers protection from predators such as bears, wolves, or coyotes.
It’s also interesting to note that beavers have another reason for cutting down trees aside from building dams. Beavers can digest cellulose, so wood is a significant food source for them, with their diet 15 also consisting of leaves and aquatic plants. Chewing on trees also helps beavers keep their teeth sharp, making it easier for them to keep chopping down trees.
Of course, no discussion about beavers would be complete without mentioning their most noticeable feature their large, flat tails, which have different uses. One is that they act as a rudder, helping them steer in the water. Another is that the animals pound their tails on the water to warn other beavers of danger. Since beavers work so hard building their homes and warning others of potential harm, it’s no surprise that busy as a beaver is a common phrase.

4 . Imagine you need milk, so you go to the grocery store to pick some up, only to find there are dozens of options. These days, you have to make a decision on not only the percentage of fat you want, but also what source you want your milk to be coming from: cows, soybeans... You have no idea what milk to pick. There are so many choices that you are confused.
This phenomenon is known as the paradox (悖论) of choice and it is becoming a concern in the modern world, where more and more options are becoming easily available to us. While we might believe that being presented with multiple options actually makes it easier to choose one that we are happy with, and thus increases consumer satisfaction, having too many options actually requires more effort to make a decision and can leave us feeling unsatisfied with our choice.
The idea was popularized by American psychologist Barry Schwartz when he published his book, The Paradox of Choice: Why More Is Less. Schwartz, who has long studied the ways in which economics and psychology intersect (交叉), became interested in seeing the way that choices were affecting the happiness of citizens in Western societies. He identified that the range of choices that we have available to us these days is far greater than that people had in the past; however, consumer satisfaction has not increased as much as traditional economics theories might expect.
Schwartz identified that the paradox of choice carries the most consequence for people that are maximizers. Maximizers, unlike satisficers, are concerned with making the best choice instead of simply making a choice that they are happy with. When there are many options available to maximizers, it becomes harder for them to determine which is the best, which can cause them to feel a great deal of regret after they have made a choice.
Instead of believing that freedom of choice is unlimited, Schwartz advocates that the role of psychology and behavioral economics should be to find the kind of limitations on freedom that can lead to the greatest level of happiness within society.

5 . Katalin Karikó and Drew Weissman, who together identified a slight chemical change to messenger RNA,were awarded the Nobel Prize in Physiology or Medicine this year.
Dr. Karikó, the 13th woman to win the prize, had come to the United States from Hungary two decades earlier when her research program there ran out of money. She was preoccupied by mRNA, which provides instructions to cells to make proteins. Defying the decades old belief that mRNA was clinically unusable, she hold the view that it would stimulate medical innovations.
She and Dr. Weissman had their first chance meeting over a copy machine at the University of Pennsylvania in 1998. At the time, Dr. Weissman was desperate for new approaches to a vaccine (疫苗) against HLV, which bad long proved impossible to defend against. A physician who had tried and failed for years to develop a treatment for AIDS, he wondered if he and Dr. Karikó could team up to make an HIV. vaccine.
For years, they were at a loss. Mice vaccinated with mRNA became inactive. Countless experiments failed. They wandered down one dead end after another, But eventually, the scientists discovered that cells protect their own mRNA with a specific chemical modification (修饰). So they tried making the same change to mRNA manufactured in the lab before vaccinating it into cells It worked.
At first, other scientists were largely uninterested in taking up that new approach to vaccination. But two biotech companies soon took notice: Moderna, in the United States, and BioNTech, in Germany. Then the coronavirus emerged. Almost instantly, Drs. Karikó and Weissman’s work came together with several factors of different research to put vaccine makers ahead of the game in developing shot.
Brian Ferguson, an immunologist at the University of Cambridge, said. “The work of Katalin Karikó and Drew Weissman in the years prior to 2020 prevented tens of millions of deaths and helped the world recover from the worst pandemic in a century. They richly deserve this recognition.”

6 . It’s often said that we human beings can dream in a foreign language. Could dreaming in a foreign language improve our memory? Does dreaming in a foreign language mean we are making progress in learning that language?
Before we look at multilingual (多语言) dreams, first we need to look at sleep. The connection between sleep and language can be applied to how we learn any language, including our native language. Even adults still learn about one new word every two days in their first language. But, if we are going to remember that new word better, what matters is that we need to connect it with what we have learned. And in order to do that, we “need to have some sleep”, says Gareth Gaskell, a professor at the University of York.
It’s during sleep that the integration (整合) of old and new knowledge happens. At might, one part of our brain — the hippocampus — takes whatever new information it receives during the day and passes it on to other parts of the brain to be stored. The role that dreams play in this night-time learning process is still being studied, but “it’s entirely possible that during multilingual dreams, the brain is trying to connect the two languages”, says Marc, a researcher at a university in Bern, Switzerland.
So having multilingual dreams could mean that our brain is trying to remember a new word or phrase. However, it could also have an emotional (情感) significance. Danuta, a professor of psycholinguistics at the University of Silesia in Poland, suggests that multilingual dreams can express “fears or wishes” around learning a foreign language, including the wish to be a local speaker or to be accepted within a certain community.
We clearly still have a lot to learn about multilingual dreams, but one thing seems certain: if you’re trying to learn a new language, you can sleep on it.

7 . In an era of endless notifications(通知) from apps, devices and social media platforms, as well as access to more information than we could possibly consider, how do we find ways to manage? And is the way we think, focus and process information changing as a result?
Maryanne Wolf is the director of the Center for Dyslexia, Diverse Learners, and Social Justice at the University of California in the United States. Wolf is concerned that “the amount of interaction we have with our screens and devices and the speed at which we necessarily have to function have changed us by removing from us the ability to be present. And we’re so accustomed to going so fast that becoming completely involved in an activity is difficult.”
Kai Lukoff is an assistant professor at Santa Clara University in the US. He researches how apps, social media platforms and technology designers attempt to attract a user’s attention. “There are a thousand or more engineers, developers, designers on the other side of the screen who are purposefully or intentionally designing these services in order to attract your attention, to get you to spend more time on the site and to get you to click on more ads.”
Daniel Le Roux is a senior lecturer at Stellenbosch University in South Africa. He looks at the effects of what we’re doing when we’re “media multitasking”. “Everybody’s doing it, and it’s, in a large way, a natural adaptation to the technological environment that has been created around us.” he said.
Media multitasking, like skimming, is an adaptive response to an environment filled with information. And media multitasking comes at a cognitive(认知的) cost. Le Roux points out. “We bring what we might call a switch cost; that means our performance in our central task is going to suffer. If you think of driving as the central task, the reason we prohibit drivers from using their smartphones while they’re driving is that it distracts them from the task of driving.”

| C．To explain why we’re media multitasking. |
| D．To show the difficulty avoiding media multitasking. |
| A．By quoting from some experts’ speeches. |
| B．By providing some typical examples. |
| C．By using the results of some surveys. |
| D．By analyzing some social phenomena. |
8 . One of the oldest metaphors (隐喻) for human interaction with technology is the relationship of master and slave. Aristotle imagined that technology could replace slavery if machine became automated. Marx and Engels saw things differently. “Masses of laborers are daily and hourly enslaved by the machine,” they wrote in the Communist Manifesto.
Today, computers often play both roles. Nicholas Carr, in his new book The Glass Cage: Automation and Us, takes a stand on whether such technology imprisons or liberates its users. We are increasingly engaged, he argues, but the invisibility of our high-tech traps gives us the ‘image of freedom’. He describes doctors who rely so much on decision-assistance software that they overlook signals that are not obvious from patients.
All of this has obvious implications for the use of technology in classrooms: When do technologies free students to think about more interesting and complex questions, and when do they destroy the very cognitive (认知) capacities that they are meant to improve? The effect of spell check and AutoCorrect software is an example. Psychologists have found the act of forming a word in your mind strengthens your capacity to remember it. When a computer automatically corrects a spelling mistake, we’re no longer forced to form the correct spelling in our minds.
This might not seem very important. The process of word formation is not just supplementing spelling skills, it’s also destroying students. When students find themselves without automated spelling assistance, they don’t face the prospect of freezing to death, as the Inuits did when their GPS malfunctioned, but they’re more likely to make errors. This creates a vicious cycle: The more we use the technology, the more we need to use it in all circumstances. Suddenly, our position as masters of technology starts to seem more insecure.

9 . While most musicians work with other artists when creating their music, Holly Herndon, an American musician and sound artist who is now based in Berlin, takes a different way, working with the machine learning software called Spawn. The software uses artificial neural networks modeled after the structure of the human brain. These networks learn patterns from datasets during the training process. Based on the data, the networks create new material that includes Herndon’s own voice.
When producing her album, PROTO, Holly trained datasets to write new music. The process requires the input data of music written by people or by artificial intelligence (AI). The neural networks then produce variations of that music. “Computers surprise you in a way that an instrument doesn’t,” Holly said. So what does music sound like when composed by what is essentially a robot? It sounds like music from the future!
But Holly Herndon isn’t the only one exploring AI in composition. Machines have played an increasingly important role in music over the last century. The godfather of computer science, Alan Turing, developed the first computer generated music in 1951. Then in 1980. David Cope from the University of California, Santa Cruz developed EMI — Experiments in Musical Intelligence, a system that analyzes existing music and produces new pieces based on it.
AI might not take over the job of the “pop star” anytime soon, or will it? Miquela Sousa is a computer-generated artist with over one million followers on Instagram. “I’m a model and singer. And I’m a robot,” Miquela said. This then raises the question: Can we reproduce creativity using a computer?
Though those questions are not easy to answer, I believe the next frontier of music lies somewhere in between. I can see the path forward with a new dawn of creativity that combines human inventiveness with AI. And the next chapter of music will certainly become wonderful as music and AI become even more closely connected.

10 . We’ve seen photographs that seem to show unbelievable images, thanks to photo editing software. But do you know you can create images that look impossible without any fancy software or computer effects?
Playing with perspective
One of the easiest tricks is called forced perspective.
Flying superheroes
How can you take a photograph of a friend so that they seem to be flying superheroes? Have your friend dress up in a superhero costume, especially one with a cape (斗篷). You can pose them outside against the open sky, and have another friend hold the cape out so it looks like they’re flying. Position yourself low and take the photo looking slightly upward so the ground isn’t visible. After you take the photo, you can cut it,
Other tricks
You can have several of your friends lie flat on a solid-colored sheet so they’re arranged to look like they’re piled in a human pyramid.
| A．so the hand holding the cape out isn’t visible. |
| B．so your friends look like they are trapped inside. |
| C．You can create your own trick photos by exploring other ways to use all these tricks. |
| D．You can also take a photo of your friend jumping up into the air. |
| E．Here are some easy tricks that can create images fooling your eyes. |
| F．The other method is to take a sheet, lay it flat on the ground, and decorate it with buildings. |
| G．To do this, you set up a camera shot with someone close to the camera and someone farther away. |
