【推荐3】Some parents will buy any high-tech toy if they think it will help their child, but researchers said puzzles help children with math-related skills.

Psychologist Susan Levine, an expert on mathematics development in young children at the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition(认知) after controlling for differences in parents’ income, education and the amount of parent talk, Levine said.

The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age.

“The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate(旋转)and translate shapes,” Levine said in a statement.

The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls.

The findings were published in the journal Developmental Science.

In which aspect do children benefit from puzzle play?

A．Building confidence.

B．Developing spatial skills.

C．Learning self-control.

D．Gaining high-tech knowledge.

Over the years, they’ve learned a lot about what features to build into a communication. But by concentrating so much on the message itself, they’ve missed a crucial component of the process.

Research done in the last 15 years shows that the best persuasion is achieved through the best pre-suasion—the practice of arranging for people to agree with a message before they even know what’s in it. Pre-suasion works by focusing people’s attention on a selected concept, which in turn encourages them to value it more than related ones.

Long before scientists started studying the process of pre-suasion, a few notable communicators already had an intuitive understanding of it.

For example, in 1588, thousands of British troops, who were gathered against a sea invasion by Spain at Tilbury in the UK, were deeply concerned that their leader Queen Elizabeth I would not be up to the rigors (严酷) of battle. In addressing the men, she removed her fears pre-suasively first acknowledging their concern by admitting a weakness, which established her honesty, and then following it with a strength that removed this perceived weakness “I know,” she stated firmly, “I have the body of a weak woman. But I have the heart of a king, and a king of England, too,” It’s reported that this statement was welcomed with long and loud cheers.

The same pre-suasive, honesty-establishing tactic was employed in the late 1950s by the advertising firm Doyle Dane Bernbach to introduce the oddly shaped Volkswagen Beetle to a US market dominated by big, powerful, boat-like vehicles. The “We’re ugly but...” campaign tactically admitted to limitations in appearance before trumpeting the auto’s strengths such as economy, reliability and simplicity. Credited with cracking open the US market for small cars, the ad campaign has been rated among the greatest of all time.

With considerable success, practitioner s(从业者) of social influence have always featured persuasive prods—enthusiastic appreciation, emotional feelings, last-chance opportunities—in their appeals. Perhaps because of that success, they’ve mostly missed an accompanying truth. For maximum impact, it’s not only what you do; it’s also what you do just before you do what you do.

What is true about pre-suasion?

A．The importance of pre-suasion has not been widely recognized.

B．All advertisers, fundraisers and politicians are good at pre-suasion.

C．Pre-suasion works by concentrating so much on the message itself.

D．Pre-suasion arrange for people to agree with an idea after knowing it

【推荐2】California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor (因素).

The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.

Many factors contributed to the decline, said Patrick McIntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources (资源).

But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, McIntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.

The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt (融雪).

Since the 1930s, McIntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.

Which of the following is well-intentioned but may be bad for big trees?

A．Ecological studies of forests.

B．Banning woodcutting.

C．Limiting housing development.

D．Fire control measures.

【推荐1】Bookstores are fascinating places. That’s because the books on the shelves can take you away to magical lands, help you learn a foreign language, or cook a delicious meal. But when your community is too small to house a real brick bookstore, sometimes you have to make a compromise. A mobile bookstore that brings books around the country was the result. That is the case for Rita Collins, 70, who dreamed of opening a used bookstore after retiring from teaching.

A business planning class from the American Booksellers Association convinced Collins to abandon her idea that opening a bookstore in the small town where she lives, which would not be sustainable. Eureka, Montana, located just seven miles from the Canadian border, only has a population of 1,517. Collins asked her instructors about a traveling bookstore on wheels and they were skeptical. But she persevered.

Collins was inspired by Dylans Mobile Bookstore, a traveling bookstore in Wales run by Jeff Towns. She contacted Jeff for advice but she was largely on her own when it came to building her bookstore. First, she had to find a vehicle large enough to stand in. Then she had to have it refitted with shelves that would hold the books at a 15-degree angle so that they would stay in place while in transit. Collins named her bookstore St Rita’s Traveling Bookstore, which has been on the road since 2015.

At first, she drove through Montana and then she made her first cross-country trip in 2016. After she retired in 2017, it became a full-time job all year round. Collins and her mobile bookstore have visited 30 states, stopping at festivals and events along the way. While the locations change, some things always stay the same. Collins loves meeting people and making connections. While she loves what she does, Collins doesn’t think she can keep doing it. In several years, she hopes to pass her traveling bookstore onto another bibliophile who shares the same interest and will keep it on the road.

Which of the following can best describe Collins?

A．Merciful and delightful.	B．Intelligent and reasonable.
C．Determined and social.	D．Generous and lovely.

【推荐2】Preparing Cities for Robot Cars

The possibility of self-driving robot cars has often seemed like a futurist’s dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn’t leading the way here. Companies have been testing their vehicles in cities across the country. It’s hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.

While much of the debate so far has been focused on the safety of driverless cars (and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions (排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.

Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing (叫车) services.

A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure (基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues (责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.

Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.

【推荐3】A tree-planting initiative in Kenya has seen over 30,000 trees being planted. The Green Generation Initiative is a Kenyan charity that has been planting trees to counter climate change and the reduction in forest in the East African nation since 2016.

......

Speaking to world leaders at the recent United Nations Climate Conference in Glasgow (COP26), Elizabeth issued a serious warning on the threat of climate change. Over two million of Kenyans are facing climate related starvation. In 2025, half of the world’s population will be facing water shortage. The climate crisis will displace 80 million people in sub-Saharan Africa alone.

Elizabeth said, “I have been doing what I can. Inspired by the great Wangari Maathai, I founded a tree growing initiative that enhances food security for young Kenyans.” So far, they have grown 30,000 fruit trees to maturity, providing desperately needed nutrition for thousands of children. “Every day we see that when we look after the trees, they look after us. We are the adults on this Earth right now, and it is our responsibility to ensure that the children have food and water,” she added.

Which of the following can best describe Elizabeth Wathuti?

A．Friendly and talented.	B．Caring and responsible.
C．Honest and determined.	D．Ambitious and humorous.
