1 . People who get a good workout almost daily can add nearly four years to their life spans, according to the first study to quantify the effect of physical activity this way.
The researchers looked at records of more than 5,000 middle-aged and elderly Americans and found that those who had moderate to high levels of activity lived1.3 to 3.7 years longer than those who got little exercise, with men and women benefiting about equally.
“This shows that physical activity really does make a difference — not only for how long you live but for how long you live a healthy life.” said Oscar H. Franco of the Erasmus M.C. University Medical Center in Rotterdam. “Being more physically active can give you more time.”
Previous studies have found that being physically active has a host of health benefits. It reduces the risk of being overweight and of developing many illnesses, improves overall quality of life, and lowers the death rate. But the new study is the first to directly calculate the effect on how long people live.
People who engaged in moderate activity — the equivalent of walking for 30minutes a day for five days a week — lived about 1.3 to 1.5 years longer than those who were less active. Those who took on more intense exercise—the equivalent of running half an hour a day five days every week—extended their lives by about3.5 to 3.7 years, the researchers found.
The findings show that even for people who are already middle-aged, exercising more can add years to their lives, Franco said.
Other experts said the study was consistent with the growing evidence that exercising on a regular basis is one of the most important things people can do for their health.
“At the end of the day, this is more evidence that the sitting lifestyle is the most damaging to health, longevity and chronic disease development,” said James O. Hill of the University of Colorado at Denver.
Hill and others said exercising regularly also enables people to live healthier lives, free from a host of chronic illnesses that can make it hard for people to enjoy their later years.
In addition, recent studies have also found that exercise has payoffs for the mind, too. It has been shown to improve overall well-being and reduce stress and depression.
“The benefits of physical activity extend well beyond the effects on longevity,” said Joann E. Manson of Harvard’s Brigham and Women’s Hospital in Boston.

2 . The Great Book Swap
Hi, sixth graders! My name is Tony Hill. I am president of the Windsor High School Student Council. Your teacher let me come to your class today to tell you about a reading project that we want to do, and we need your help.
If you’re like me, you love to read but sometimes have a hard time finding books you want to read. It seems as if the best books at the library are always checked out. To help get more books into people’s hands, we’re planning the Great Community (社区) Book Swap.
To make the project a success, we need everyone’s help. Ask your parents if there are any unused books taking up space. Ask your friends and neighbours to donate unwanted books. Maybe you have books you liked when you were younger but don’t read anymore. Bring them to school and make a young reader happy. We need all kinds of books for all kinds of readers!
There are many times I’d like to go buy new books, but I don’t have a lot of money to spend on them. Wouldn’t it be great to swap books right here in our community? Volunteers will organize the donated books. Then the books will be displayed at the community center. Everyone will be able to read and hopefully find the perfect book. Students will be allowed to choose up to two books during each day of the swap. Our plan is to have the book swap the first Saturday of every month.
If you like reading, just come and look through the collection of books. Each grade will have its own week to bring in books. Right now, eighth grade is bringing in books. When every grade has brought in books, we will have quite a selection. You will probably find at least one new book that you’d like to read. Who knows? Maybe you’ll find a book so good that you won’t be able to put it down.
What are you waiting for? Go home and clean out your bookshelves and closets!

If you listen to the stream of articles and podcasts telling us how to become a billionaire in 10 easy steps, you might hold the belief that squeezing ourselves dry each second of the day will bring happiness and success.
But this obsession with productivity is costing us. Even a car doesn’t stay in the same gear the whole time. “We are not machines,” says psychologist Professor Drew Dawson. “Performance declines as a function of time, of task and time of day.”
Instead of moments of boredom, where we might let our minds wander and come up with novel solutions to problems and novel ways of thinking, we seek constant stimulation - and have a lowered tolerance for boredom as a result.
“It leads people to a false assumption that the world’s most successful people are literally making good use of every single minute,” Dawson says. “That’s a myth. We’re not hardwired to act that way as humans, and it’s a good recipe for burnout.”
COVID-19, for a variety of reasons, has led people to question and even opt out of this myth. “Who wants to lie on their deathbed going, ‘I wish I’d been more productive’?” Dawson says. “Post-COVID, people are starting to say, ‘what am I losing compared to what am I gaining?’”
So, if not more productivity, what should we be aiming for?
·Get our priorities straight.
A life spent chasing the state of being able to do everything is less meaningful than a life of focusing on a few things that count. We can reflect on five things that matter most to us and lead a life around them. Once clear on them, we also become clear on where to direct our attention and what to say “no” to.
·Enjoy downtime(停工期)for its own sake
Glorifying productivity can blind us to the value of other parts of our lives, including boredom, connection, creativity and play. But activities in our lives don’t need to always be productive or worthwhile-enjoying an activity is reason enough to spend time on it.
We weren’t meant to be productive all the time, so stop constantly struggling, and start chilling.
1. What does “obsession with productivity” refer to in the passage?2. How has COVID-19 changed the situation according to the passage?
3. Please decide which part is false in the following statement, then underline it and explain why.
It is more meaningful to focus on a few things that count in life, so we can reflect on five things in our life to say “no” to. 4. Do you agree with the statement “enjoying an activity is reason enough to spend time on it”? Why or why not?(In about 40 words)
4 . There’s nothing like family. The people we’re related to by blood and marriage are expected to be our greatest sources of love and support. Too often, however, our interactions with family are filled with misunderstanding and resentment. Those we should know and be known by best, end up feeling like adversaries or strangers.
Family is where our first and strongest emotional memories are made, and that’s where they keep appearing. And this is why emotional intelligence(EQ)succeeds where other efforts at family harmony fail.
Look to yourself first. A family is a system made up of interdependent individuals, but that doesn’t mean you can blame your family of origin for the way you are today
Recognize that being close doesn’t mean being clones. Sometimes family ties blind us to the uniqueness of those we love. Pride in the family continuum can make it easy to forget that. You can’t be expected to have the same talents as your siblings, even though you may look a lot alike.
Cherish every stage of life in each family member. No matter how well we understand that it can’t happen, we desperately want Mom and Dad to stay the way they are, and for the kids to stay home forever.
| A．Your best hope for fixing any family problem is to attend your own emotional health. |
| B．You won’t necessarily choose to follow in parent’s footsteps. |
| C．It’s also important to keep your awareness active with family. |
| D．The best to accept that fact emotionally, is to embrace change. |
| E．People all change, and yet many seem to only see change in themselves. |
| F．If you’re not sure what will work, ask. |
| G．Active awareness and empathy tell us how to respond to one another’s needs. |
Is social media messing with children’s morals?
Parents are often concerned about the effects of social media on their children’s character. We have all heard complaints that young people are spending too much time online and not enough time in the “real world” —with studies showing that nearly three-quarters of 12 to 15-year-olds in the UK have a social media profile and spend an average of 19 hours a week online.
More worrying, perhaps, than the amount of time spent online, are the findings that suggest social media use can actually influence users’ personality and character. Recent research, for example, shown that there is a link between social media use and narcissism (自恋), and that the use of social networking websites may have an nagative effect on social decision making and reduce levels of empathy (同情心).
With this in mind, one of the latest research projects at the Jubilee Centre for Character and Virtues, looks at the impact social media has on young people’s character and moral development, and aims to understand the benefits social media can have on development.
The first stage of the research involved a “parent poll (survey)” of 1,738 parents of 11 to 17-year-olds from across the UK asked a series of questions on their feelings around social media, and the moral (or immoral) messages that appear online. Our findings so far indicate that parents’ attitudes towards social media are largely negative–over a half of parents we questioned agree that social media “hinders or weakens” a young person’s character or moral development. While only 15% of respondents agreed that social media could “enhance or support” it.
However, it isn’t all doom and gloom, because our research also shows that social media can be a source for good. Nearly three quarters of the parents who use social media on a regular basis reported seeing content with a positive moral message at least once a day-including humour, appreciation of beauty, creativity, kindness, love and courage. And it could well be, that viewing this type of positive online content could have a positive influence on young people’s attitudes and behaviours.
This is because on social media sites, users often come across new perspectives and situations-such as different religions, cultures and social groups. And exposure to these situations online could actually help young people be more understanding and tolerant—and in turn develop their empathy skills. This is because it allows them to view things from other people’s perspectives, in a way they might not be able to in “real life”.
Of course, this translation from exposure to empathy may not always follow-which can be seen in the high rates of cyber bullying. According to a 2015 report, 62% of 13 to 20-year-olds who had been bullied reported some degree of cyber bullying—which shows that empathy doesn’t always play a part in online environments.
But while it may be tempting for some parents to just ban social media use altogether, it is unlikely to be a successful strategy in the long term-social media is not going away. Instead, we need to better understand the relationship between social media use and a young person’s character and moral values. And through our research, we hope to be able to offer constructive evidence-based advice on exactly this.
Because it is clear that the online environment is a moral terrain which requires successful navigation. By understanding how some immoral events can be avoided, we can help to create a safer and more even path for young people to negotiate.

| G．Celebrations always involve people coming together and helping each other to have a good time. |
Alle Pierce knows how to plan a holiday. A few months ahead of time, she constructs a spreadsheet of what she wants to do and see. She examines the menus of restaurants she is planning to visit. She uses a picture of the destination as her phone’s locked screen image and downloads a countdown app. “What’s so exciting about a trip is the anticipation before it,” says Pierce, founder of a luxury travel company.
Experts stay she is right. Recent studies suggest that hoping for something boosts your mood and lowers your stress. “Imagining good things ahead of us can increase motivation, optimism and patience,” says Simon Rego, a psychologist from New York.
Of course we can’t just book a flight every time we need a little cheering up or feel low. But there are ways to incorporate the power of anticipation into your everyday life.
Get excited about little things. Write down one thing you’re excited for tomorrow. Maybe it’s a new book, or a package you’re expecting. The collection of these mini thrills means you will still gain the benefits of looking forward to something. Plus, with the nearer stuff, there’s more of a sense that it’s going to happen for sure.
Remember that anxiety and anticipation can coexist. “The dark side of positive anticipation is anticipatory anxiety. Anxiety and excitement are sister emotions,” says Christian Waugh, a psychology professor from North Carolina. But it is harmful only when you just focus on the anxiety part and ignore the excitement part. The key is acknowledging the happy, positive aspect of what you are doing, along with the nervous feelings. When you consider anxious things as exciting, it actually makes you feel better about them.
Connect with your future self. Research has shown feeling as if you are on a path to your future self can have a positive effect on your well-being by getting you out of short-term thinking. Thinking ahead may help you prioritize your goal and move toward it. As you start seeing progress, you will look forward to doing the things that get you closer to your future self.
In short, to enjoy life more, embrace anticipation. It’s worth waiting for.

8 . An AI model can be used to detect stress in office workers based on how they use their mouse and keyboard. A new study suggests that a machine-learning model using these two elements was more accurate at detecting stress in people than a model that tracked their heart-rate data.
“We saw that the models that just used the mouse and keyboard data performed better than the models that had the heart-rate data in it,” says Mart Naegelin. a Ph. D. student at the Swiss Federal Institute of Technology, and one of the study’s authors.
Naegelin and her fellow researchers used machine-learning models to analyze data on keyboard-typing activity, mouse movements and heart-rate data. They also studied the data of a combination of two or all three of these elements to determine which performed best in terms of measuring stress. They found that the model trained on mouse and keyboard data performed better than the model that used mouse, keyboard and heart rates. Of the single-modality (形态) models, the heart-rate data performed the worst. “The test was conducted in an environment that simulated an office environment, so the results still need to be confirmed in real-life scenarios (情况),” Naegelin says.
In the experiment, participants were divided into three groups. A control group carried out assigned tasks, such as planning meetings and collecting data, with no additional work. A second group at times answered questions from managers in person in a mock interview scenario while completing other assigned tasks. And members of a third group were, at certain points, interrupted with additional questions sent through an online chat on top of tasks assigned to other groups. At regular intervals during the experiment, participants were asked to rate their stress levels through a computer questionnaire.
Researchers learned that workers made longer, less accurate movements with their mouse, as well as more typing errors, when they were stressed. Shorter, more direct movements with the mouse were tied to lower stress levels. The study didn’t focus on why increased levels of stress are thought to affect muscle activity.
The researchers say they believe a stress-detection system that logs keyboard and mouse movements might be beneficial as a self-help tool for employees alongside other initiatives to improve workplace mental health. But employee participation would need to be optional and based on informed consent (同意), and companies would need to commit to protecting user privacy.
It remains to be seen how this technology will evolve and be adopted in practice, but the potential for AI to contribute positively to employee well-being is an appealing avenue for future exploration.

When I was an undergraduate student studying ecology, I was used to discovering overall trends in large amounts of data. The thought of getting my hands dirty in the field never seemed interesting to me. I saw it as a boring and repetitive task. But I knew potential graduate schools would likely view my lack of field experience as a hole in my application letter. My mother also thought I should work for a few years to explore my interests before pursuing further education. So I decided to apply for field-based summer positions after graduation.
After landing a job assessing the sage grouse habitat in Utah, I found myself in the company of Sherel, a 75-year-old botanist and the leader of our field crew. On the very first day of the fieldwork, I noticed a special plant on the field. “Wonderful! Looks like you’ve got a Mahonia repens,” Sherel shouted excitedly. I gently touched the plant with yellow flowers by my feet, “This one here? How can you tell it’s a Mahonia?” He paused briefly to admire the plant and then began his energetic description of the plant’s typical features. That evening, while we were watching the sunset together, I texted my childhood friend. “Day I was actually kind of fun,” I started, “but we’ll see how long it takes before I get bored from just identifying plants in the field all day.”
But as the weeks of fieldwork rolled by, the boredom I had expected never arrived. I came home from the field each night with sore legs and a sunburned neck, excited by the day’s finds. By picking Sherel’s brain about different species of animals and plants, I discovered field days are about much more than identification. Each day is an opportunity to learn a little bit more. When the summer was over, I found myself in another field job, this time surveying forest in Michigan’s Upper Peninsula.
I’m now a third-year Ph. D. student in ecology. Fieldwork may be buggy, wet, and physically demanding, but working with others helps keep spirits high and the physical activity helps me stay sharp. And it constantly reminds me that any task can present an opportunity to learn — as long as I am open to it.

10 . Frozen in time, a 125-million-year-old mammal attacking a dinosaur. A 39-million-year-old whale, the heaviest animal that ever lived. The oldest known jellyfish, from 505 million years ago. Paleontology (古生物学) produces newsworthy discoveries.
Fossils (化石), moreover, provide direct evidence for the long history of life, allowing paleontologists to test hypotheses (假设) about evolution with data only they provide. They allow investigation of present and past life on Earth. Flows of biological diversity, appearances of new life forms and the extinctions of long existing ones, would go undiscovered without these efforts. But the headlines over exciting new fossils greatly underestimate the true importance of paleontology. Its real significance lies in how such discoveries brighten the grand history of life on Earth. From its beginnings, more than three billion years ago, to the present day, fossils record how life adapted or disappeared in the face of major environmental challenges.
Paleontologists provide us with a unique vantage on modern climate change. They play an essential role in interpreting ancient environments, in reconstructing ancient oceans, continents and climates. Fossils provide key limitation on the climate models that are essential for predicting future climate change. And the fossil record gives important insights into how life will respond to predicted future climate conditions, because these have occurred before in Earth’s history.
In addition, paleontology has provided a fundamental contribution to human thought: the reality of species extinction and thus of a world that has dramatically changed over time. In documenting the history of life, paleontologists recognized that many extinction episodes could occur suddenly, such as the event 66 million years ago that ended the dinosaurs. The search for the causes of past mass extinctions started pioneering studies from across the scientific spectrum (科学界), focusing on potential future threats to humanity.
Not only do paleontologists know what happens to life when things go bad, they also know how long it takes for ecosystems and biodiversity to recover from these disasters, which can take far longer than modern humans have existed.
Paleontologists thus provide a unique perspective on the nature and future long-term ecological impact of the current human-produced biodiversity crisis, the so-called Sixth Extinction, and therefore the importance of protecting modern biodiversity. The very concept of a Sixth Extinction would not exist without paleontologists documenting the first five.
Paleontologists know that understanding life’s past is critical to anticipating and adapting to life’s and humanity’s future. Paleontology is important because it brings its unique and critical perspective to current challenges in climate change, biodiversity loss and the environment. Paleontologists can predict the future because they know the past.
