1 . This question has fascinated behavioural scientists for decades: why do we give money to charity?
The explanations for charitable giving fall into three broad categories, from the purely altruisic (利他的)— I donate because I value the social good done by the charity. The “impurely” altruistic— I donate because I extract value from knowing I contribute to the social good for the charity. And the not-at-all altruistic— I donate because I want to show off to potential mates how rich I am.
But are these motives strong enough to enable people to donate as much as they would want to? Most people support charities in one way or another, but often we struggle to make donations as often as we think we should. Although many people would like to leave a gift to charity in their will, they forget about it when the time comes.
Many people are also aware that they should donate to the causes that have the highest impact, but facts and figures are less attractive than narratives. In a series of experiments, it was found that people are much more responsive to charitable pleas that feature a single, identifiable beneficiary(受益者), than they are to statistical information about the scale of the problem being faced. When it comes to charitable giving, we are often ruled by our hearts and not our heads.
The good news is that charitable giving is contagious—seeing others give makes an individual more likely to give and gentle encouragement from an important person in your life can also make a big difference to your donation decisions— more than quadrupling them in our recent study. Habit also plays a part— in three recent experiments those who volunteered before were more likely to do donate their time than those who had not volunteered before.
In summary, behavioural science identifies a range of factors that influence our donations, and can help us to keep giving in the longer term. This is great news not just for charities, but also for donors.

2 . Obese people experience discrimination (歧视) in many parts of their lives, and the workplace is no exception. Studies have long shown that obese workers, defined as those with a body-mass index (BMI) of 30 or more, earn significantly less than their slimmer co-workers.
Yet the costs of weight discrimination may be even greater than previously thought. “The overwhelming evidence,” wrote the Institute for employment Studies, “is that it is only women living with obesity who experience the obesity wage penalty (薪资损失).” They were expressing a view that is widely aired in academic papers. To test it, The Economist has analyzed data concerning 23,000 workers from the American Time Use Survey, conducted by the Bureau of Labour Statistics. Our number-processing suggests that, in fact, being obese hurts the earnings of both women and men.
The data we analyzed cover men and women aged between 25 and 54 and in full-time employment. At a general level, it is true that men’s BMIs are unrelated to their wages. But that changes for men with university degrees. For them, obesity is associated with a wage penalty of nearly 8%, even after accounting for the separate effects of age, race, graduate education and marital status.
The conclusion — that well-educated workers in particular are penalized for their weight — holds for both sexes. Moreover, the higher your level of education, the greater the penalty. We found that obese men with a Bachelor’s degree (学士学位) earn 5% less than their thinner colleagues, while those with a Master’s degree earn 14% less. Obese women, it is true, still have it worse: for them, the equivalent figures are 12% and 19%, respectively (分别地).
Your line of work makes a difference, too. When we dealt with the numbers for individual occupations and industries, we found the greatest differences in high-skilled jobs. Obese workers in health care, for example, make 11% less than their slimmer colleagues; those in management roles make roughly 9% less, on average. In sectors such as construction and agriculture, meanwhile, obesity is actually associated with higher wages.
These results suggest that the total costs of wage discrimination borne by overweight workers in America are greater than expected. Now, it’s time for our governments to take it seriously.

3 . Growing up on a mountain farm in Tyrol, Fritz enjoyed watching how cows and horses interacted with each other more freely, once they’d been led out of the barn and into pasture. It was what he observed in his boyhood that took root in his pursuit of becoming a biologist. After he finished his study at university. Fritz landed work at Austria’s Konrad Lorenz Research Center, raising raven chicks by hand and teaching graylag geese how to open boxes as he pursued his PhD. Working this closely with free-living animals was exactly what he’d dreamed of as a boy.
In 1997, a zoo gave the research center its first northern bald ibis chicks (隐鹮) Nowhere near as teachable as geese—and not even close to super intelligent ravens—the ibises frustrated most of the scientists. But Fritz was fascinated. He devoted himself to taking care of them. After the ibises were first released back into the wild more than 20 years ago, Fritz learned that spending generations in zoo hadn’t reduced their drive to migrate (迁徙), though it did leave them geographically uninformed. In their search for “south”, some ended up in Russia. What the ibises needed, Fritz thought, was a guide.
Fritz decided he would teach the birds a new, safer migration route by guiding them himself in a tiny aircraft. And he was confident he could succeed in this daring, unconventional plan—because he had done it before. “Around that time, the movie ‘Fly Away Home’ was a huge hit with us biologists,” Fritz says. When he announced that he’d do the same with the ibises, he was initially laughed at. But Fritz didn’t give up. He modified an ultralight aircraft so it would travel at speeds slow enough for his winged students to keep up. He had been his young pupils’ only provider of food, love and hugs since they were just a few days old, and the ibises eagerly followed their teacher, who just happened to pilot a fairly noisy machine.
In 2004, three years after some initially bumpy (颠簸的) experiments, Fritz led the first batch of birds from Austria to Italy, and has since led 15 such migrations. Over that time, he has rewilded 277 young ibises, many of which then started to pass the route on to their own young.

4 . Scientists train AI to read human thoughts
Scientists have created a new tool that can turn people’s thoughts into words. It works by using an AI program called GPT-1 to translate brain activity words. In order to achieve this, scientists did a lot.
First, scientists got everything ready before the tests. They invited some volunteers. Each spent sixteen hours listening to stories in a scanner (扫描仪). They imagined the stories as they heard them, and the scanner recorded their brain activity. GPT-1 made connections between the ideas in the stories and the recordings of the listeners’ brain activity.
Then came the tests. The scientists did them in three different ways.
Test 1
The researchers played a new story. GPT-1 was only given recordings of the volunteers’ brain activity. But the words that GPT-1 predicted were very similar to the words in the story that they were listening to. The words weren’t exactly the same, but they often carried the same meaning. For example, when a volunteer was listening to a story about a woman who didn’t have a driver’s license, the program came up with this: “She hasn’t even started to learn to drive yet.”
Test 2
The scientists also carried out the test when volunteers imagined their own stories. “It really works at the level of ideas. The ideas are the same but expressed in different words,” says Alexander Huth, one of the scientists behind the study.
Test 3
The researchers showed the volunteers silent movies, with no spoken words at all. GPT-1 could still figure out the basic ideas.
After the tests, the scientists say that GPT-1 is the first AI program to turn what people are thinking into words without brain surgery (外科手术). The tool isn’t something that can be easily used today, mainly because of the size and the cost of the scanner. In the future, they believe, a similar but cheaper tool could help people who have lost the ability to speak because of an injury or disease.
The scientists say their tool can’t be used to “read people’s minds” without permission. The tool only works if the person wants to share their thoughts.

5 . In the United States, most of our electricity comes from power plants(发电厂) that burn coal and oil.
There are two big problems with using these things for electricity. First. their supply is limited(有限的). Second, burning them causes pollution. So to make sure we always have power and to keep our planet clean, we must find other ways to make electricity.
Some people think that wind power is our best choice. First, there will always be more wind. Also, wind power does not pollute the environment. Best of all, we don’t have to search for wind.
Today, less than 1 percent of our electricity comes from wind. But scientists have been developing better wind machines. As a result, wind power is getting more popular in this country.
Yet wind power may not keep growing so quickly in years to come. Why not? Many wind turbines(风力涡轮机)are needed to make much electricity. So wind-power companies try to build wind farms but are competing(竞争)with other uses for the land. A wind farm is a group of turbines placed close together in an area with frequent winds.
In places where companies try to build wind farms, people think that lines of turbines are ugly. Noise from turbines often troubles people. Also, turbines kill birds that fly into them.
Wind-power supporters disagree. They think the sight of wind turbines is lovely. They point out that people have gotten used to living near noisy highways. They say ways can be found to keep birds away from turbines.
In today’s world, we need clean and unlimited power sources more than ever. Unless a better power source comes along, people may just have to accept wind power as a part of their lives.
1. The underlined part “these things” in the second paragraph refers to _______.| A．frequent winds. | B．coal and oil. |

6 . Washing machines are one of the greatest inventions of the last few centuries.They have made life easier. Unfortunately, washing machines also contribute to the environmental issues of energy use and micro-plastics flowing into the oceans. That is why the washing machine manufacturer (制造商), Samsung, and the outdoor-wear company, Patagonia, are working together to make a change.
For Patagonia, the issue of micro-plastics has been on its mind for years — its woolen jackets release many microfibers. As for Samsung, new requirements throughout the world have forced many producers to start thinking about ways to help reduce the number of micro-plastics. There are currently more than 14 million tons of micro-plastics floating in the oceans. Though people previously think of things such as plastic bottles and fishing lines when it comes to plastics in the ocean, thousands of micro-plastics are released into seas with every wash.
The issue is a sort of catch-22. In order to reduce energy costs, manufacturers try to make their machines more efficient. These machines use hotter water and are designed to create more friction (摩擦) between the clothing in the machine. However, both of these things lead to the release of more micro-plastics. So, using Patagonia clothes as test cases, Samsung came up with a two-fold solution: One is a technology called Eco-bubbles, which creates more bubbles to make the detergent (洗涤剂) more powerful, and the other is a water purifier that can filter (过滤) out more micro-plastics.
The cooperation between the two companies is proof of how complicated protecting the environment can be. On the one hand, clothing that is well-constructed and durable is a weapon in the fight against fast fashion. On the other hand, the material used to make those clothes and the way they are washed can also add pollutants to the environment.The same goes for washing machines. There is no one-size-fits-all solution. The fight against climate change requires creative thinking and learning how to attack a problem from many angles. This will certainly lead to even more strange and fruitful cooperation between the environmentally conscious companies.

7 . Being a writer in the 21st century can keep you in front of a screen for so long that it feels like the room is sideways. Being a human with the Internet can mean hours spent on social media, scrolling and posting for so long that your sense of reality
I grew up in the city, not hiking or camping, so I knew nothing about the outdoors. I have three kids with endless energy, so I figured I could solve two questions at once. I would get a breather from my job and the kids would play with insects and realize there is nothing better than nature.
We drove to Great Falls, Virginia, where hundreds of people on any given day spent hours meandering through the hillside and forest. The blue water pulsed, turning white and crashing powerfully hundreds of feet beneath us. The kids held their breath as if they had seen magics. But it’s just nature, just the outside, and that had been there all along. Since then, we’ve been fascinated.
Last summer I felt my home’s walls closing in, so I decided to go camping. I built my first fire. My kids watched my every move, asking every ten minutes to help get more branches and roast meat. About a month, my craving to take a break from the city grew again. We camped two more times before the cold came, each time seeing a bit more of what nature had to offer city folks.

8 . Underwater travel is difficult and dangerous, but many people have reasons to stay deep under the ocean. Soldiers in submarines travel long distances underwater. Companies looking for oil and other resources stay underwater, too. Humans have come up with a few designs of vehicles to move around under the ocean. But what if there was a better way to travel?
Hilary Bart-Smith, an engineer at the University of Virginia, thinks a vehicle that travels like a man ta ray would be able to operate for long periods at sea as if it were a living organism. Manta rays, a type of cartilaginous (软骨的) fish, can grow up to 29 feet long, which are found throughout the world in tropical, subtropical, and temperate waters. Manta rays are some of the most efficient swimmers in the ocean. Different from animals and people pushing against water in order to swim, the manta ray swims by moving through the water with wing-like movements of their fins (鳍). Efficiency means using less energy to move farther and causing less pollution.
Bart-Smith and other engineers at the University of Virginia had to find out what manta rays looked like on the inside to better understand how they move. They took x-rays to find out how a manta ray’s fins are built. They found that a web of cartilage, which is the same kind of material that your ears and nose are made from, stretches across each fin.
Once the engineers knew how a manta ray’s fin was constructed, they could build one of their own. They made a long row of metal struts with many hinges to imitate the manta ray’s web of cartilage, acting like your finger, which can bend as one long line, or bend in many places to make a curve. The engineers put their design inside a flexible cover, shaped like a manta ray’s fin. Then they tested it in the university swimming pool. They were happy to see that it swam just like a manta ray in the ocean.
Engineers and scientists are still learning and experimenting with how to imitate these amazing animals. Perhaps someday engineers will be able to build manta ray robots that are big enough to transport people. For now, engineers study their movement and learn from the most efficient swimmers in the ocean.

9 . A man named Randy liked to look for big trees and old trees. He made maps to show where these trees were. He did not want to cut them down. He wanted people to take care of them.
Randy was told that there was a very tall tree on Vancouver Island. The tree was said to be 314 feet tall. That would make it the tallest tree in Canada. Randy started to find the tree.
But someone else found it first. It was found by a logger (伐木工). Loggers wanted to cut down Canada’s tallest tree and all the trees around it.
Randy made a path in the forest so people could see the tallest tree. The tree was so big and beautiful that it would bring them enjoyment. More and more people wanted to save that forest. Thanks to these people, that forest is now a park. Canada’s tallest tree is still there.

10 . Pamela Malhotra has always attached great importance to education. However, life always seemed to “get in the way” every time she tried to finish her bachelor’s degree. The single mom was so devoted to working to support her two children that she repeatedly put her own education goals on hold, giving up her college program on two separate occasions over the years.
When he was just five years old, her son Bonifacio Malhotra noticed her struggling to get her degree, and he made a promise to help her. “I remember I just told my mom… one day, it’s gonna be you and me,” Bonifacio said. “We’re going to gain our degrees at the same time.” Those words proved to be predictable for the mom-and-son duo, who currently walked across the stage at the university to collect their bachelor’s degrees together!
“That promise, he never allowed it to die,” said Pamela. “He continuously confirmed that we’re gonna do this.” Their path to graduation wasn’t easy, but Bonifacio stayed true to his promise and helped his mother along the way. The two hold two associate’s degrees each, so in the fall of 2021 they registered together in bachelor-level online courses. They both found the classes challenging, but Bonifacio stepped up as the cheerleader his mother needed. “Mom, you’ve got to keep it going. I know you want to stop. We must keep going,” Bonifacio recalled. “The main thing was just trying to get everything lined up and stay on top of all the work.”
It took the Malhotras two years to finish their bachelor’s degrees, hers in humanities and Bonifacio’s in public safety administration. Pamela plans to stay at her job as a coordinator, and Bonifacio has accepted a job at university to help other students succeed in college, too.
Pamela said she was incredibly proud of her son’s achievement, and she personally couldn’t have reached her lifelong goal without the support of her family, especially him. “Between my son and my daughter, they were my greatest supporter,” Pamela proudly said.
1. Why Pamela Malhotra couldn’t finish her bachelor’s degree?| A．Because she didn’t work hard enough. |
