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.

2. What are the selected artworks about?

A．Wealth and intellect.	B．Home and school.
C．Books and reading.	D．Work and leisure.

3. What do the underlined words “relate to” in paragraph 2 mean?

A．Understand.	B．Paint.
C．Seize.	D．Transform.

4. What does the author want to say by mentioning the e-reader?

A．The printed book is not totally out of date.

B．Technology has changed the way we read.

C．Our lives in the 21st century are networked.

D．People now rarely have the patience to read.

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.

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

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.     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

8 . If you want to tell the history of the whole world, a history that does not privilege one part of humanity, you cannot do it through texts alone, because only some of the world has ever had texts, while most of the world, for most of the time, has not. Writing is one of humanity’s later achievements, and until fairly recently even many literate (有文字的) societies recorded their concerns not only in writing but in things.

Ideally a history would bring together texts and objects, and some chapters of this book are able to do just that, but in many cases we simply can’t. The clearest example of this between literate and non-literate history is perhaps the first conflict, at Botany Bay, between Captain Cook’s voyage and the Australian Aboriginals. From the English side, we have scientific reports and the captain’s record of that terrible day. From the Australian side, we have only a wooden shield (盾) dropped by a man in flight after his first experience of gunshot. If we want to reconstruct what was actually going on that day, the shield must be questioned and interpreted as deeply and strictly as the written reports.

In addition to the problem of miscomprehension from both sides, there are victories accidentally or deliberately twisted, especially when only the victors know how to write. Those who are on the losing side often have only their things to tell their stories. The Caribbean Taino, the Australian Aboriginals, the African people of Benin and the Incas, all of whom appear in this book, can speak to us now of their past achievements most powerfully through the objects they made: a history told through things gives them back a voice. When we consider contact (联系) between literate and non-literate societies such as these, all our first-hand accounts are necessarily twisted, only one half of a dialogue. If we are to find the other half of that conversation, we have to read not just the texts, but the objects.

1. What is the first paragraph mainly about?

A．How past events should be presented.	B．What humanity is concerned about.
C．Whether facts speak louder than words.	D．Why written language is reliable.

2. What does the author indicate by mentioning Captain Cook in paragraph 2?

A．His report was scientific.	B．He represented the local people.
C．He ruled over Botany Bay.	D．His record was one-sided.

3. What does the underlined word “conversation” in paragraph 3 refer to?

A．Problem.

B．History.

C．Voice.

D．Society.

4. Which of the following books is the text most likely selected from?

A． How Maps Tell Stories of the World	B． A Short History of Australia
C． A History of the World in 100 Objects	D． How Art Works Tell Stories

9 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

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.
