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.

4 . Reading Art: Art for Book Lovers is a celebration of an everyday object — the book, represented here in almost three hundred artworks from museums around the world. The image of the reader appears throughout history, in art made long before books as we now know them came into being. In artists’ representations of books and reading, we see moments of shared humanity that go beyond culture and time.
In this “book of books,” artworks are selected and arranged in a way that emphasizes these connections between different eras and cultures. We see scenes of children learning to read at home or at school, with the book as a focus for relations between the generations. Adults are portrayed (描绘) alone in many settings and poses —absorbed in a volume, deep in thought or lost in a moment of leisure. These scenes may have been painted hundreds of years ago, but they record moments we can all relate to.
Books themselves may be used symbolically in paintings to demonstrate the intellect (才智), wealth or faith of the subject. Before the wide use of the printing press, books were treasured objects and could be works of art in their own right. More recently, as books have become inexpensive or even throwaway, artists have used them as the raw material for artworks — transforming covers, pages or even complete volumes into paintings and sculptures.
Continued developments in communication technologies were once believed to make the printed page outdated. From a 21st-century point of view, the printed book is certainly ancient, but it remains as interactive as any battery-powered e-reader. To serve its function, a book must be activated by a user: the cover opened, the pages parted, the contents reviewed, perhaps notes written down or words underlined. And in contrast to our increasingly networked lives where the information we consume is monitored and tracked, a printed book still offers the chance of a wholly private, “off-line” activity.
1. Where is the text most probably taken from?| A．An introduction to a book. | B．An essay on the art of writing. |
| C．A guidebook to a museum. | D．A review of modern paintings. |
| A．Wealth and intellect. | B．Home and school. |
| C．Books and reading. | D．Work and leisure. |

5 . 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. |
| 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. |
| A．To conserve pollinators. | B．To restrict solar development. |
| C．To diversify the economy. | D．To ensure the supply of energy. |
| 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 |
6 . 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 |
A MOTHER’S DAY SURPRISE
The twins were filled with excitement as they thought of the surprise they were planning for Mother’s Day. How pleased and proud Mother would be when they brought her breakfast in bed. They planned to make French toast and chicken porridge. They had watched their mother in the kitchen. There was nothing to it. Jenna and Jeff knew exactly what to do.
The big day came at last. The alarm rang at 6 a.m. The pair went down the stairs quietly to the kitchen. They decided to boil the porridge first. They put some rice into a pot of water and left it to boil while they made the French toast. Jeff broke two eggs into a plate and added in some milk. Jenna found the bread and put two slices into the egg mixture. Next, Jeff turned on the second stove burner to heat up the frying pan. Everything was going smoothly until Jeff started frying the bread. The pan was too hot and the bread turned black within seconds. Jenna threw the burnt piece into the sink and put in the other slice of bread. This time, she turned down the fire so it cooked nicely.
Then Jeff noticed steam shooting out of the pot and the lid starting to shake. The next minute, the porridge boiled over and put out the fire. Jenna panicked. Thankfully, Jeff stayed calm and turned off the gas quickly. But the stove was a mess now. Jenna told Jeff to clean it up so they could continue to cook the rest of the porridge. But Jeff’s hand touched the hot burner and he gave a cry of pain. Jenna made him put his hand in cold water. Then she caught the smell of burning. Oh dear! The piece of bread in the pan had turned black as well.

9 . By day, Robert Titterton is a lawyer. In his spare time though he goes on stage beside pianist Maria Raspopova — not as a musician but as her page turner. “I’m not a trained musician, but I’ve learnt to read music so I can help Maria in her performance.”
Mr Titterton is chairman of the Omega Ensemble but has been the group’s official page turner for the past four years. His job is to sit beside the pianist and turn the pages of the score so the musician doesn’t have to break the flow of sound by doing it themselves. He said he became just as nervous as those playing instruments on stage.
“A lot of skills are needed for the job. You have to make sure you don’t turn two pages at once and make sure you find the repeats in the music when you have to go back to the right spot.” Mr Titterton explained.
Being a page turner requires plenty of practice. Some pieces of music can go for 40 minutes and require up to 50 page turns, including back turns for repeat passages. Silent onstage communication is key, and each pianist has their own style of “nodding” to indicate a page turn which they need to practise with their page turner.
But like all performances, there are moments when things go wrong. “I was turning the page to get ready for the next page, but the draft wind from the turn caused the spare pages to fall off the stand,” Mr Titterton said, “Luckily I was able to catch them and put them back.”
Most page turners are piano students or up-and-coming concert pianists, although Ms Raspopova has once asked her husband to help her out on stage.
“My husband is the worst page turner,” she laughed. “He’s interested in the music, feeling every note, and I have to say: ‘Turn, turn!’ Robert is the best page turner I’ve had in my entire life.”
1. What should Titterton be able to do to be a page turner?| A．Read music. | B．Play the piano. |
| C．Sing songs. | D．Fix the instruments. |
| A．Boring. | B．Well-paid. |
| C．Demanding. | D．Dangerous. |
| A．Counting the pages. | B．Recognizing the “nodding”. |
| C．Catching falling objects. | D．Performing in his own style. |
| A．He has very poor eyesight. | B．He ignores the audience. |
| C．He has no interest in music. | D．He forgets to do his job. |
