1 . On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the “wisdom of crowds” effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate.

This effect capitalizes on the fact that when people make errors, those errors aren’t always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won’t cancel each other out. In more technical terms, the wisdom of crowds requires that people’s estimates be independent. If for whatever reasons, people’s errors become correlated or dependent, the accuracy of the estimate will go down.

But a new study led by Joaquin Navajas offered an interesting twist (转折) on this classic phenomenon. The key finding of the study was that when crowds were further divided into smaller groups that were allowed to have a discussion, the averages from these groups were more accurate than those from an equal number of independent individuals. For instance, the average obtained from the estimates of four discussion groups of five was significantly more accurate than the average obtained from 20 independent individuals.

In a follow-up study with 100 university students, the researchers tried to get a better sense of what the group members actually did in their discussion. Did they tend to go with those most confident about their estimates? Did they follow those least willing to change their minds? This happened some of the time, but it wasn’t the dominant response. Most frequently, the groups reported that they “shared arguments and reasoned together”. Somehow, these arguments and reasoning resulted in a global reduction in error. Although the studies led by Navajas have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous.

2 . Personal Forgiveness

Taking responsibility for mistakes is a positive step, but don’t beat yourself up about them. To err (犯错) is human.     1     You can use the following writing exercise to help you do this.

In a journal or on a piece of paper, put the heading “Personal strengths.”     2     Are you caring? Creative? Generous? A good listener? Fun to be around? They don’t have to be world-changing, just aspects of your personality that you’re proud of.

At the top of a second page, put the heading “Acts of kindness.” On this one, list all the positive things you’ve done for others. It might be the time when you helped a friend with their homework, when you did the ironing without being asked, or when you baked cookies after the family had had a tiring day.     3    

You could ask a friend or family member to help add to your list.     4     That way, you could exchange thoughts on what makes each of you special and the aspects of your personality that shine through. In fact, don’t wait until you’ve made a mistake to try this — it’s a great way to boost self-confidence at any time.

It’s something of a cliché (陈词滥调) that most people learn not from their successes but their mistakes. The thing is, it’s true.     5     We’ re all changing and learning all the time and mistakes are a positive way to develop and grow.

A．A little self-forgiveness also goes a long way.

B．Now list all the characteristics you like about yourself.

C．They might even like to have a go at doing the exercise.

D．It’s just as important to show yourself some forgiveness.

E．It doesn’t mean you have to ignore what’s happened or forget it.

F．Whatever it is, no matter how small it might seem, write it down.

G．Whatever the mistake, remember it isn’t a fixed aspect of your personality.

3 . The goal of this book is to make the case for digital minimalism, including a detailed exploration of what it asks and why it works, and then to teach you how to adopt this philosophy if you decide it’s right for you.

To do so, I divided the book into two parts. In part one, I describe the philosophical foundations of digital minimalism, starting with an examination of the forces that are making so many people’s digital lives increasingly intolerable, before moving on to a detailed discussion of the digital minimalism philosophy.

Part one concludes by introducing my suggested method for adopting this philosophy: the digital declutter. This process requires you to step away from optional online activities for thirty days. At the end of the thirty days, you will then add back a small number of carefully chosen online activities that you believe will provide massive benefits to the things you value.

In the final chapter of part one, I’ll guide you through carrying out your own digital declutter. In doing so, I’ll draw on an experiment I ran in 2018 in which over 1,600 people agreed to perform a digital declutter. You’ll hear these participants’ stories and learn what strategies worked well for them, and what traps they encountered that you should avoid.

The second part of this book takes a closer look at some ideas that will help you cultivate (培养) a sustainable digital minimalism lifestyle. In these chapters, I examine issues such as the importance of solitude (独处) and the necessity of cultivating high-quality leisure to replace the time most now spent on mindless device use. Each chapter concludes with a collection of practices, which are designed to help you act on the big ideas of the chapter. You can view these practices as a toolbox meant to aid your efforts to build a minimalist lifestyle that works for your particular circumstances.

4 . Turning soil, pulling weeds, and harvesting cabbage sound like tough work for middle and high school kids. And at first it is, says Abby Jaramillo, who with another teacher started Urban Sprouts, a school garden program at four low-income schools. The program aims to help students develop science skills, environmental awareness, and healthy lifestyles.

Jaramillo’s students live in neighborhoods where fresh food and green space are not easy to find and fast food restaurants outnumber grocery stores. “The kids literally come to school with bags of snacks and large bottles of soft drinks,” she says. “They come to us thinking vegetables are awful, dirt is awful, insects are awful.” Though some are initially scared of the insects and turned off by the dirt, most are eager to try something new.

Urban Sprouts’ classes, at two middle schools and two high schools, include hands-on experiments such as soil testing, flower-and-seed dissection, tastings of fresh or dried produce, and work in the garden. Several times a year, students cook the vegetables they grow, and they occasionally make salads for their entire schools.

Program evaluations show that kids eat more vegetables as a result of the classes. “We have students who say they went home and talked to their parents and now they’re eating differently,” Jaramillo says.

She adds that the program’s benefits go beyond nutrition. Some students get so interested in gardening that they bring home seeds to start their own vegetable gardens. Besides, working in the garden seems to have a calming effect on Jaramillo’s special education students, many of whom have emotional control issues. “They get outside,” she says, “and they feel successful.”

5 . As an artist who shares her journey on social media, I’m often asked by curious followers how to begin an art journey. Unfortunately, there is no magic list I can offer. I do remember, though, what it was like to be a complete beginner. So I’ve put together some good tips for starting an art journey.

·Start small. I suggest using a sketchbook (素描本) for small studies. These small studies provide inspiration and may be a springboard for more complex works in the future.     1     You’ll want to look back on your journey to see how far you’ve come.

·Paint often and paint from life. There’s no better way to improve than to put in those brush miles. Whether you paint still lifes, portraits, or landscapes, paint from life as much as possible.     2    

·Continually challenge yourself to try something new.     3     Artistic growth can be a bit painful. Welcome to the club；we’ve all been there. I love taking on challenges. I once took up a challenge to create a painting every day for a month and post the works online.

·    4     Seeking and accepting constructive feedback (反馈) is crucial to growth. I post my work on social media and, in turn, have met some of the kindest people. They make me feel valued and respected, no matter my level of artistic ability.

The journey you’re on won’t follow a straight path.     5     Push through, give it time and put in the effort. You will harvest the rewards of an artistic life.

A．Get out of your comfort zone.

B．Make career plans and set goals.

C．Don’t throw away your beginner art.

D．Share your work if you feel comfortable doing so.

E．You’ll hit roadblocks, and you’ll feel discouraged at times.

F．Evaluate your performance and, if needed, redefine your role.

G．You’ll develop that painting muscle memory that only comes with repetition.

6 . According to the Solar Energy Industry Association, the number of solar panels installed(安装)has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.

Solar developers want to put up panels as quickly and cheaply as possible, so they haven’t given much thought to what they put under them. Often, they’ll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.

“Solar projects need to be good neighbors,” says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE)project. “They need to be protectors of the land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).

Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms.

Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that’s going on in the landscape,” says Macknick.

1. What do solar developers often ignore?

A．The decline in the demand for solar energy.

B．The negative impact of installing solar panels.

C．The rising labor cost of building solar farms.

D．The most recent advances in solar technology.

2. What does InSPIRE aim to do?

A．Improve the productivity of local farms.

B．Invent new methods for controlling weeds.

C．Make solar projects environmentally friendly.

D．Promote the use of solar energy in rural areas.

3. What is the purpose of the laws mentioned in paragraph 4?

A．To conserve pollinators.	B．To restrict solar development.
C．To diversify the economy.	D．To ensure the supply of energy.

4. Which of the following is the best title for the text?

A．Pollinators: To Leave or to Stay	B．Solar Energy: Hope for the Future
C．InSPIRE: A Leader in Agriculture	D．Solar Farms: A New Development

7 . Indoor plants might look as if they just sit around not doing much, but in many ways they are the unsung heroes of the home.     1    , but studies have shown that they can promote people’s wellbeing by improving their mood (心情), reducing stress and helping their memory. What’s more, indoor plants are easy to look after and are not very expensive.

What are indoor plants?

Indoor plants, also known as houseplants or pot plants, are plants that like to grow indoors. Many of these species (物种) are not ideally suited to growing outside in the UK, especially in the winter.     2    .

Why are indoor plants good for you?

Will Spoelstra, who works at the Royal Botanic Gardens, says, “    3    . I find during the winter months, plants around the house can really lift your mood.” Several studies have backed this up and found that indoor plants can improve creativity, focus and memory. There is also research showing that pot plants can clean the air around them by removing harmful gases, such as carbon dioxide. They also remove some harmful chemicals from paints or cooking.     4    .

Which plants can you grow?

Aloe vera, peace lilies and spider plants are some of the species that are easy to grow indoors. You can buy plants from supermarkets, garden centres or online. Younger plants are often cheaper than fully grown ones, and you get to care for them as they mature — which is part of the joy of owning plants. “    5    ,” Spoelstra says. “It can bring a new interest and focus into people’s lives and help to make the link between home and nature.”

A．All plants are different

B．Not only do they look beautiful

C．There are many benefits to growing plants indoors

D．Instead, they grow better inside, where it is warmer

E．Plants like peace lilies and devil’s ivy are among the best

F．Changing the pot of your plant from time to time will also help

G．Learning about the requirements of each plant can be very rewarding

8 . Tricks To Becoming A Patient Person

Here’s a riddle: What do traffic jams, long lines and waiting for a vacation to start all have in common? There is one answer.     1    .

In the Digital Age, we’re used to having what we need immediately and right at our fingertips. However, research suggests that if we practiced patience, we’d be a whole lot better off. Here are several tricks.

●Practice gratitude (感激)

Thankfulness has a lot of benefits: Research shows it makes us happier, less stressed and even more optimistic.     2    . “Showing thankfulness can foster self-control,” said Ye Li, researcher at the University of California.

● Make yourself wait

Instant gratification (满足) may seem like the most “feel good” option at the time, but psychology research suggests waiting for things actually makes us happier in the long run. And the only way for us to get into the habit of waiting is to practice.     3    . Put off watching your favorite show until the weekend or wait 10 extra minutes before going for that cake. You’ll soon find that the more patience you practice, the more you start to apply it to other, more annoying situations.

●     4    .

So many of us have the belief that being comfortable is the only state we will tolerate, and when we experience something outside of our comfort zone, we get impatient about the circumstances. You should learn to say to yourself, “    5    .” You’ll then gradually become more patient.

A．Find your causes

B．Start with small tasks

C．Accept the uncomfortable

D．All this adds up to a state of hurry

E．It can also help us practice more patience

F．This is merely uncomfortable, not intolerable

G．They’re all situations where we could use a little extra patience

9 . PRACTITIONERS

Jacqueline Felice de Almania (c.1322) highlights the suspicion that women practicing medicine faced. Born to a Jewish family in Florence, she moved to Paris where she worked as a physician and performed surgery. In 1322 she was tried for practicing unlawfully. In spite of the court hearing testimonials (证明) of her ability as a doctor, she was banned from medicine.	James Barry (c.1789 — 1865) was born Margaret Bulkley in Ireland but, dressed as a man, she was accepted by Edinburgh University to study medicine. She qualified as a surgeon in 1813, then joined the British Army, serving overseas. Barry retired in 1859, having practiced her entire medical profession living and working as a man.
Tan Yunxian (1461 — 1554) was a Chinese physician who learned her skills from her grandparents. Chinese women at the time could not serve apprenticeships (学徒期) with doctors. However, Tan passed the official exam. Tan treated women from all walks of life. In 1511, Tan wrote a book, Sayings of a Female Doctor, describing her life as a physician.	Rebecca Lee Crumpler (1831 — 1895) worked as a nurse for eight years before studying in medical college in Boston in 1860. Four years later, she was the first African American woman to receive a medical degree. She moved to Virginia in 1865, where she provided medical care to freed slaves.

1. What did Jacqueline and James have in common?

A．Doing teaching jobs.	B．Being hired as physicians.
C．Performing surgery.	D．Being banned from medicine.

2. How was Tan Yunxian different from the other practitioners?

A．She wrote a book.	B．She went through trials.
C．She worked as a dentist.	D．She had formal education.

3. Who was the first African American with a medical degree?

A．Jacqueline Felice de Almania.	B．Tan Yunxian.
C．James Barry.	D．Rebecca Lee Crumpler.

10 . With gas prices rising and airport security lines snaking longer than ever, why not book your next domestic vacation on a train? Compared to other alternatives, it’s comfortable and relaxing. Here is some advice on how to make a trip by rail as pleasant as possible.

Plan ahead. Most long-distance trains, especially the sleeping car accommodations, sell out very quickly.     1     But no matter when you travel, it’s a good idea to make your reservations at least 90 days in advance.

Use a travel agent. Consider turning your travel plan over to a travel agent and letting him double-check all the details, make suggestions, and then handle the actual reservations. A good one can sometimes find you discounted tickets.     2     Then you won’t have to walk through several cars on a moving train three times a day for your meals.

Bring a blanket. When you’re riding on trains, you won’t be provided with a blanket for free, even if your trip is an overnight one.     3     In the summer in particular, the air conditioning can make them quite cold.

Arrive early. Most trains operate just once a day and some run only three times a week, so missing yours can be a disaster.     4     Note: The times listed on the schedules are departure times, not arrival times.

Have fun.     5     Read a book, knit, do a crossword puzzle, or simply watch the world unfold outside the window. To calculate your speed as you do, divide 3,600(the number of seconds in an hour)by the number of seconds it takes you to travel one mile(the distance between two mileposts). If it takes the train 53 seconds to travel one mile, you’re going 67.92 mph.

A．Train trips aren’t for impatient types.

B．You’ll have views from both sides of the train.

C．The temperature on rail cars is often hard to control.

D．That’s particularly true during busy summer months.

E．You might have to wait longer than 24 hours to catch the next one.

F．Chances are the cost will be a lot less than the cost of one bedroom.

G．He may also book you in a sleeping car that’s right next to the diner.
