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.

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 . When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.
After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.
The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.
He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.
Over the years, John has taken on many big jobs. He developed a greenhouse — like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.
“Ecological design” is the name John gives to what he does. “Life on Earth is kind of a box of spare parts for the inventor,” he says. “You put organisms in new relationships and observe what’s happening. Then you let these new systems develop their own ways to self-repair.”

8 . The elderly residents (居民) in care homes in London are being given hens to look after to stop them feeling lonely.
The project was dreamed up by a local charity (慈善组织) to reduce loneliness and improve elderly people’s wellbeing. It is also being used to help patients suffering dementia, a serious illness of the mind. Staff in care homes have reported a reduction in the use of medicine where hens are in use.
Among those taking part in the project is 80-year-old Ruth Xavier. She said: “I used to keep hens when I was younger and had to prepare their breakfast each morning before I went to school. ”
“I like the project a lot. I am down there in my wheelchair in the morning letting the hens out and down there again at night to see they’ve gone to bed.”
“It’s good to have a different focus. People have been bringing their children in to see the hens and residents come and sit outside to watch them. I’m enjoying the creative activities, and it feels great to have done something useful.”
There are now 700 elderly people looking after hens in 20 care homes in the North East, and the charity has been given financial support to roll it out countrywide.
Wendy Wilson, extra care manager at 60 Penfold Street, one of the first to embark on the project, said: “Residents really welcome the idea of the project and the creative sessions. We are looking forward to the benefits and fun the project can bring to people here.”
Lynn Lewis, director of Notting Hill Pathways, said: “We are happy to be taking part in the project. It will really help connect our residents through a shared interest and creative activities.”
1. What is the purpose of the project?| A．To ensure harmony in care homes. | B．To provide part-time jobs for the aged. |

9 . What comes into your mind when you think of British food? Probably fish and chips, or a Sunday dinner of meat and two vegetables. But is British food really so uninteresting? Even though Britain has a reputation for less-than-impressive cuisine, it is producing more top class chefs who appear frequently on our television screens and whose recipe books frequently top the best seller lists.
It’s thanks to these TV chefs rather than any advertising campaign that Britons are turning away from meat-and-two-veg and ready-made meals and becoming more adventurous in their cooking habits. It is recently reported that the number of those sticking to a traditional diet is slowly declining and around half of Britain’s consumers would like to change or improve their cooking in some way. There has been a rise in the number of students applying for food courses at UK universities and colleges. It seems that TV programmes have helped change what people think about cooking.
According to a new study from market analysts, 1 in 5 Britons say that watching cookery programmes on TV has encouraged them to try different food. Almost one third say they now use a wider variety of ingredients (配料) than they used to, and just under 1 in 4 say they now buy better quality ingredients than before. One in four adults say that TV chefs have made them much more confident about expanding their cookery knowledge and skills, and young people are also getting more interested in cooking. The UK’s obsession (痴迷) with food is reflected through television scheduling. Cookery shows and documentaries about food are broadcast more often than before. With an increasing number of male chefs on TV, it’s no longer “uncool” for boys to like cooking.
1. What do people usually think of British food?| A．It is simple and plain. | B．It is rich in nutrition. |
| C．It lacks authentic tastes. | D．It deserves a high reputation. |
| A．Authoritative. | B．Creative. | C．Profitable. | D．Influential. |
| A．20%. | B．24%. | C．25%. | D．33%. |
| A．The art of cooking in other countries. | B．Male chefs on TV programmes. |
| C．Table manners in the UK. | D．Studies of big eaters. |
10 . Living in Iowa and trying to become a photographer specializing in landscape (风景) can be quite a challenge, mainly because the corn state lacks geographical variation.
Although landscapes in the Midwest tend to be quite similar, either farm fields or highways, sometimes I find distinctive character in the hills or lakes. To make some of my landscape shots, I have traveled up to four hours away to shoot within a 10-minute time frame. I tend to travel with a few of my friends to state parks or to the countryside to go on adventures and take photos along the way.
Being at the right place at the right time is decisive in any style of photography. I often leave early to seek the right destinations so I can set up early to avoid missing the moment I am attempting to photograph. I have missed plenty of beautiful sunsets/sunrises due to being on the spot only five minutes before the best moment.
One time my friends and I drove three hours to Devil’s Lake, Wisconsin, to climb the purple quartz (石英) rock around the lake. After we found a crazy-looking road that hung over a bunch of rocks, we decided to photograph the scene at sunset. The position enabled us to look over the lake with the sunset in the background. We managed to leave this spot to climb higher because of the spare time until sunset. However, we did not mark the route (路线) so we ended up almost missing the sunset entirely. Once we found the place, it was stressful getting lights and cameras set up in the limited time. Still, looking back on the photos, they are some of my best shots though they could have been so much better if I would have been prepared and managed my time wisely.
