2 . 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 . Personal Forgiveness
Taking responsibility for mistakes is a positive step, but don’t beat yourself up about them. To err (犯错) is human.
In a journal or on a piece of paper, put the heading “Personal strengths.”
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.
You could ask a friend or family member to help add to your list.
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.
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. |

5 . 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 . 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.
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.
● 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.
●
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, “
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 . Like most of us, I try to be mindful of food that goes to waste. The arugula (芝麻菜)was to make a nice green salad, rounding out a roast chicken dinner. But I ended up working late. Then friends called with a dinner invitation. I stuck the chicken in the freezer. But as days passed, the arugula went bad. Even worse, I had unthinkingly bought way too much; I could have made six salads with what I threw out.
In a world where nearly 800 million people a year go hungry, “food waste goes against the moral grain,” as Elizabeth Royte writes in this month’s cover story. It’s jaw-dropping how much perfectly good food is thrown away — from “ugly” (but quite eatable) vegetables rejected by grocers to large amounts of uneaten dishes thrown into restaurant garbage cans.
Producing food that no one eats wastes the water, fuel, and other resources used to grow it. That makes food waste an environmental problem. In fact, Royte writes, “if food waste were a country, it would be the third largest producer of greenhouse gases in the world.”
If that’s hard to understand, let’s keep it as simple as the arugula at the back of my refrigerator. Mike Curtin sees my arugula story all the time — but for him, it's more like 12 bones of donated strawberries nearing their last days. Curtin is CEO of DC Central Kitchen in Washington, D.C., which recovers food and turns it into healthy meals. Last year it recovered more than 807,500 pounds of food by taking donations and collecting blemished (有瑕疵的) produce that otherwise would have rotted in fields. And the strawberries? Volunteers will wash, cut, and freeze or dry them for use in meals down the road.
Such methods seem obvious, yet so often we just don’t think. “Everyone can play a part in reducing waste, whether by not purchasing more food than necessary in your weekly shopping or by asking restaurants to not include the side dish you won’t eat,” Curtin says.

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.
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.
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.
Arrive early. Most trains operate just once a day and some run only three times a week, so missing yours can be a disaster.
Have fun.
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. |
