1 . Get Better at Saying No
“No” is a short, simple word that can cause anxiety for the person trying to say it. The following strategies can help you get better at saying no.
Be intentional about what you communicate.Not every situation, of course, calls for such a thoughtful approach. Think through times when you’ve gotten stressed over delivering a quick “no”, and then brainstorm phrases you could use in the future. Bohns, for example, is often asked to donate to some cause or another as she checks out at the grocery store.
There’s always that one guy who won’t take no for an answer. If someone is applying undue pressure, adopt what psychologist Ellen Hendriksen describes as the broken-record technique.
A.She says no directly. |
B.It’s sticking to your answer. |
C.Adopt the broken-record technique. |
D.Repeat your request again and again. |
E.She now has a go-to response: “I already donated this year.” |
F.One way to do that is by thanking people for thinking of you. |
G.You might have heard the tip that “no” is a complete sentence. |
2 . Social media and the Internet are powerful tools that are an important part of our everyday lives. We use them to learn, communicate, work, and more.
Schedule your Internet time
A hobby gives you something to spend time on that’s not the Internet. Take a yoga class, start learning to play an instrument, start gardening, sign up for the gym, or do anything else that interests you. At the beginning, commit to spend just 1 hour a week on the hobby, then gradually ram p up the hours or take up more hobbies. Make sure you turn off your phone or hide your devices while you do your chosen hobby.
Spend more time with friends offline.
Make it a point to schedule in-person social activities. Go to dinner with friends once a week, get together with a group of people for a weekend hike, or reach out to people you haven’t seen in a while and schedule a catch-up date. If you feel like you don’t have anyone to spend time with, reach out to acquaintances and ask them to join you for lunch or a coffee—you can always make new friends!
A.Cut out Internet use for a set period each week. |
B.Do a screen-free hobby for at least an hour a week. |
C.Using technology right before bed can negatively affect sleep quality. |
D.But, sometimes, using them too much can negatively affect our lives. |
E.Create a clear division between Internet time and time for other things. |
F.You can also join a club to spend more time on off line social activities. |
G.So you don’t get interrupted or distracted by social media and the Internet. |
3 . A team at a US university trained an AI tool to examine 60,000 fingerprints to see if it could work out which ones belonged to the same individual. The researchers claim the technology could identify, with 75-90% accuracy, whether prints from different fingers came from one person.
But they are not sure how it works. “We don’t know for sure how the AI does it,” admitted Prof Hod Lipson, a roboticist at Columbia University who led the study.
Graham Williams, professor of forensic science (法医学) at Hull University, said the idea of unique fingerprints had never been set in stone. “We don’t actually know that fingerprints are unique,” he said. “All we can say is that as far as we are aware, no two people have yet to show the same fingerprints.”
The results of Columbia University’s study could have the potential to impact both biometrics and forensic science.
If, for example, an unidentified thumb (拇指) print is found at crime scene A, and an unidentified index (食指) fingerprint at crime (犯罪) scene B, the two could not currently be forensically connected to the same person—but the AI tool could be able to identify this.
The Columbia University study will be published in the journal Science Advances on Friday. But a pair of twins in Cheshire might be ahead of everyone. Their grandmother Carol told the BBC her two grandchildren can open each other’s iPhones using their own fingers.
“They showed me on Christmas day,” she said. “We were told they were identical when they were born but I can tell the difference between them as they’ve got older.”She claimed that her grandchildren can also bypass the handsets’ facial recognition feature.
Fingerprints are formed before birth. Research published last year suggested the genetic process behind them may be similar to the way animals like zebras and leopards get their markings.
1. According to the research, what can AI tools do?A.Identifying people’s fingerprints. |
B.Contributing to crime prevention. |
C.Helping lead scientific studies and experiments. |
D.Training people to tell the difference of fingerprints. |
A.Unique. | B.Healthy. | C.The same. | D.Cute. |
A.All twins share the same fingerprints. | B.People’s fingerprints may not be unique. |
C.AI will replace humans in every way. | D.Fingerprints will change as people grow older. |
A.To make an appeal to people to protect animals. |
B.To tell the difference between people and animals. |
C.To explain the formation principle of fingerprints. |
D.To show the similarity of genes between animals and people. |

5 . Pick up any packaged processed food, and there’s a decent chance that one of its listed ingredients will be “natural flavour”. The ingredient sounds good, particularly in contrast to “artificial flavours” since there is a common belief that ingredients from nature are necessarily safer than something artificially made. But it’s not true. Then what exactly does the natural flavour mean? It refers to extracts (提取物) got from natural sources like plants, meat or seafood. When consumers see the “natural flavour” on a label, they are unlikely to assume that someone is squeezing the juice from oranges into their bottles. They know even though natural flavour must come from natural sources, it needn’t all come from the plant or meat. For example, orange flavours might contain not only orange extracts, but also extracts from bark and grass.
So if flavours like orange are needed, why not just use oranges? The answer comes down to “availability, cost, and sustainability”, according to flavour chemist Gary Reineccius of the University of Minnesota. “If you’re going to use all your grapes on grape soda,” Reineccius says, “you don’t have any grapes for wine making; the products are going to be exorbitant; besides, what do you do with the by-products you create after you’ve squeezed all the juice out of the grapes?”
Actually, while chemists make natural flavours by extracting chemicals from natural ingredients, artificial flavours are made by creating the same chemicals artificially. The reason why companies bother to use natural flavours rather than artificial flavours is simple: marketing. “Many of these products have health titles,” says Platkin, professor from Hunter College. “Consumers may be talked to believe products with natural flavours are healthier, though they are nutritionally no different from those with artificial flavours. Natural flavours may involve more forest clear-cutting and carbon emissions from transport than flavours created in the lab.”
Platkin suggests getting more transparent (易懂的) labeling on packaging that describes exactly what the natural or artificial flavours are, so consumers are-not misled into buying one product over another because of “natural flavours”. Reineccius also offers simple guidance: “Don’t buy anything because it says ‘natural flavours’. Buy it because you like it.”

6 . New research confirms that human footprints found in New Mexico are probably the oldest direct evidence of human presence in the Americas, a finding that upends what many scientists knew about human habitation and migration (迁徙).
The footprints were discovered at the edge of an ancient lakebed in White Sands national park. According to the new paper published in the journal Science, they date back to between 21,000 and 23,000 years ago. Actually, the estimated age of the footprints was first reported in Science in 2021, but some researchers raised concerns about the dates. Questions focused on whether seeds of water plants used for the original dating may have absorbed ancient carbon from the lake — which could, in theory, throw off radiocarbon dating (碳14年代测定) by thousands of years. But the new study presents two additional lines of evidence for the older date range. It uses two entirely different materials found at the site, ancient pollen (花粉) and stone grains.
The reported age of the footprints challenges the once conventional wisdom that humans did not reach the Americas until a few thousand years before rising sea levels covered the Bering land bridge between Russia and Alaska, perhaps about 15,000 years ago. “This is a subject that’s always been controversial (有争议的) because it’s so significant. It’s about how we understand the last chapter of the peopling of the world,” said Thomas Urban, an archaeologist (考古学家) at Cornell University, who was involved in the 2021 study but not the new one.
Thomas Stafford, an independent archaeological geologist in New Mexico, who was not involved in the study, said he “was a bit suspicious (怀疑的) before” but now is convinced. The new study isolated about 75,000 grams of pure pollen from the same stone layer that contained the footprints. “Dating pollen is laborious but worthwhile,” said Kathleen Springer, a research geologist at the US Geological Survey and a co-author of the new paper.
Ancient footprints of any kind can provide archaeologists with a quick look of a moment in time. While some archeological sites in the Americas point to similar date ranges — including necklaces carved from giant animal remains in Brazil — scientists still question whether such objects really indicate human presence. “White Sands is unique because there’s no question these footprints were left by people,” said Jennifer Raff, a scientist at the University of Kansas, who was not involved in the study.

7 . To the human ears, a field of flowers is silent, except the noise of birds and insects. To certain animal ears, however, a field of flowers is full of conversation. Now, scientists have discovered that plants actually make noise as a way of communicating. In other words, they talk!
It has long been known that plants communicate when they are stressed. You need only watch a houseplant to realize that a plant lowers its head when it needs water, or turns yellow when it has been watered too much. Some plants also send out a bad smell when stressed to try and stop insects from taking advantage of their stressed state and eating them up.
Now, a new study that was published in Cell and conducted by researchers at Tel Aviv University, shows that not only do plants express themselves in the above ways when stressed, they also make sounds, like talking.
According to NoCamels, plants send out sounds at frequencies (频率) between 40 to 80 kilohertz—out of the range (范围) of human ears, but within the range of some animals. “Bats (蝙蝠) make sounds in these ranges all the time, and mice, dogs and cats can partly hear within it,” Dr. Lilach Hadany, one of the authors of the study, told NoCamels.
What is surprising about Hadany’s study is that the researchers have managed to understand and group the sounds that plants make for the first time. Plants that are not stressed make about one noise per hour, but plants that are stressed, thirsty, or injured make many hundreds of sounds per hour; and each of these sounds seems to show the certain type of stress the plant is under.
This type of information could be key for agriculture (农业). Knowing what sounds their plants are making will help farmers determine whether their plants are in danger or disease and allow them to make the necessary changes to allow their plants to grow well.

8 . Last Monday, I visited Jalan Besar to find a new fan blade (风扇叶片) for a standing fan that my daughters had broken.
I worked in the Jalan Besar area 30 years ago and remembered that there were lots of small hardware shops selling unusual things so I thought that I would have no problem finding a fan blade. However, after walking around for almost an hour, I found out that these shops were no longer around.
When I was ready to give up and go home, I spotted an old-fashioned hardware store. After being greeted by a woman, I explained my predicament. She immediately asked me to show her the broken blade. Out of nowhere, a man who looked to be in his 60s came out.
He asked to see the blade and then disappeared into the shop. He came back with a blade but it did not look the same as what I had in my hand. We compared the two blades and he said that it might work.
I asked him how much it was. He told me that he had taken the blade off an old fan that someone had brought in for repair. He said, “It didn’t cost me anything, so why should I charge you for it?” That really touched me. I took the blade home and it worked perfectly! My daughters got a “new” fan for nothing.
When I told my wife (almost in her 60s) this story, she said this reminded her of the kind aunties and uncles who used to run small shops and were always ready to help others when she was growing up.

9 . At some point, something will have to be done about the stuffed toys (毛绒玩具). I haven’t counted them because, truthfully, I’m not prepared to know how many there are. Lately, our neighborhood’s message boards are filled with posts about parents trying to make space, to clear out the things their kids no longer need. The tone of some of these posts can best be described as “emergency”. “Help!” they sometimes begin. “I have to get this out of my house.”
“The proliferation (激增) of children’s toys is the outcome of a long, gradual cultural change,”says Gary Cross, a professor at Pennsylvania State University. To understand how we got here — drowning (淹没于) in all those stuffed toys and bricks — it helps to look as far back as the late 19th century. “Parents were no longer passing their jobs on to the children,” Cross says. “Instead, they connect across generations through the gifting process. From the early 20th century on, goods became the things that define relationships between family members, and the way of marking success as a family.”
Then, how can parents deal with the proliferation of children’s toys at home? Naeemah Ford Goldson, a professional organizer, is also a mom of two. In her own home, Goldson likes to include her kids in the work of sorting out their toys. They know that the items they don’t need anymore will be given to people who can use them, to families who might not be as fortunate as theirs. “Doing so helps them build those habits of letting go,” she says, “so then they don’t become adults who are too dependent on material things instead of experiences, or people, and the memories we make with people.”
Her idea made sense. She told her 5-year-old they should pick some to give to kids in their community who came from another country and had to leave their toys behind. She immediately took a pink bear from the pile.

10 . While you may get flowers or a card from the one you love on Valentine’s Day, it can be hard to know how our four-legged friends feel about us.
Happy greeting
It’s great to be welcomed home by our pet and your dog isn’t doing this to show welcome to you;
When your pet chooses to look at you with soft, relaxed eyes, they trust you and are happy in your company, accepting you as non-threatening. And, it could be argued, that trust is the highest form of love.
Hugs (on your pet’s terms)
Your dog can choose to curl up wherever they like, so when they hug you, they are actively choosing you. This can range from full body hugs to them leaning into you to ask for some love. However, any hug must always be on your pet’s conditions and personalities.
Tail wagging
A wagging tail can display a whole range of emotions from your dog, but you’ll know it’s a sign of love when they treat you to a full body wiggle. Their tail will turn around in circular movements like helicopter propellers (螺旋桨).
Licking you
Your dog may lick you for a variety of reasons, but one of them is affection and love. They are ultimately seeking attention from you because they want to interact with you.
A.Soft eye contact. |
B.Cheerful and excited barking. |
C.Actually, it’s a sign that they are pretty happy to see you. |
D.In actuality, it’s a sign that they are hungry and eager for some treats. |
E.Some dogs will find having someone’s arms around them stressful and uncomfortable. |
F.Our cats and dogs can’t tell us how they feel, so what are the other signs that you share a special connection? |
G.This type of tail wagging is usually reserved for people that are special to them, and is mostly used when dogs see their owners. |
