People of all cultures have special stories they pass down. Aboriginal (土著的) Australians have a long history of telling stories. They call it “Dreaming”. Many Dreaming stories are thousands of years old.
Europeans came to Australia in 1788. At that time, Aboriginal people had been there for 60,000 years. There were 270 tribes (部落), and each one spoke a different language. Only tribal members were allowed to take part in Dreaming. If they drew symbols during Dreaming, tribal members had to erase them. Most people drew these symbols in the dirt. That way, they could erase them after Dreaming.
When Europeans moved into Australia, they wanted the Aboriginal people to become more like them. In 1959, they built a town called Papunya. They asked Aboriginal tribes to move there. In Papunya, the Europeans hoped the Aboriginal people would become part of European culture. However, Aboriginal people wanted to hold on to their own cultures. That was difficult in Papunya. The tribes were also living with each other for the first time. Slowly, parts of each tribe’s culture began to die out. Today, only 18 of the 270 languages remain strong.
Still, Aboriginal people held on to their Dreaming stories. In 1971, a group of students in Papunya shared their stories with each other during an art class. Their teacher noticed what they were doing. He wanted them to use the symbols in their artwork.
However, they wanted to protect their tradition. To do so, they hid their Dreaming symbols in the dots of each painting. That way, only other people from their tribe could truly understand the message of the painting. Soon, the practice of Aboriginal dot painting (点画) became widespread. Aboriginal dot paintings can’t be fully understood by outsiders. However, many still enjoy the paintings as art. Dot painting became popular in the late 20th century. Today, Aboriginal artists continue to conceal their Dreaming symbols.

British Columbia is known as a great attraction for tourists, Alberta is known for its oil and natural gas, and Saskatchewan is known for its large wheat fields. Ontario is known as being the business center of the country. But Quebec is best known for being different from the rest of Canada. It is “the French Canada” because of its large French-speaking population, some of whom want to break away from the other English speaking provinces of Canada.
In Canada, most people speak English as their first language and the two national television networks broadcast in English throughout the country. Apart from in Quebec and a few places on the east coast, there are few television programs in French.
The same goes for traffic signs and menus. For example, outside of Quebec, there are only a few places where you’ll see traffic signs in French. In restaurants, it’s almost impossible to find French on the menu unless you are in the heartland of French Canada. However, all products sold in Canada must, by law, have labels (标签) and instructions in both languages.
Canada is now one of the few nations in the world to have two official languages: English and French. In Canada’s English speaking provinces, the two-official-language reality means that students can choose to complete a special French language course. If they begin the course in kindergarten or Grade One, it is likely that all their lessons will be in French. However, if they start at junior high school, 25 percent of the teaching will continue to be in English.

Few countries are as corrupt as Congo(刚果). Mobutu Sese Seko, a former strongman, used state funds to charter a Concorde to take him on shopping trips to Paris. By the time of his overthrow in 1997, graft was endemic. Government employees were not paid but rather expected to use their positions to make a living. Among the most prized government jobs was that of accountant: the people responsible for transporting bags of cash to the provinces to hand out to employees.
In 2012, however, the Congolese government started helping civil servants to open bank accounts. Around three-quarters of them—some 670,000 people—now have one. In the process, the government has weeded out tens of thousands of ghost employees, since the embezzlers who invented them could not open accounts in their names without a matching ID.
Yet in a vast country with fewer roads than Luxembourg, hardly anyone lives anywhere near a bank branch. So Congolese banks must now do the work the government accountants used to: shipping money to the remote area. Cash has to be transported to branches in regional capitals, and thence to account-holders on the backs of motorbikes, in canoes or by foot. Bank staff with suitcases of cash make easy targets, just as they did in the west of America in the 19th century. Though they usually travel with armed policemen, there have been at least ten armed robberies of bank employees since January.
At the moment banks are little more than money-transfer companies, and not very sophisticated ones at that. The transfers tend to go only one way—out of Kinshasa—so cannot be netted against each other; instead cash almost always has to be moved physically. Therefore, most Congolese bankers hope that the new system will promote the growth of a proper banking system.

【推荐3】An international group of coffee experts has considered Ethiopia’s coffee as the best in the world.Coffee is a top export (出口物) of the country. But at home, it is seen as national pride. Ethiopians feel good about their coffee, and enjoying a drink with friends is a long tradition.
Some people say the climate produces quality beans. Morton Wennersgarrd is a coffee importer. He said, “Ethiopia has different ancient types of coffee. They are planted in places with perfect soil, perfect altitude (海拔), and climates that are really suitable for coffee processing.”
Finding the best quality beans is often an issue of taste. The process is known as cupping — tasting and comparing coffee from different roasted beans, grading and then pricing them. But before international experts come to taste, coffee beans are studied in small coffee laboratories. Helen Assefa, a lab technician, describes the process, “When the coffee comes to the lab, we assess (评价) its quality first by recording the details.Then we weigh the moisture (水分) level and we examine the beans for analysis. After that we grind (磨碎) the coffee beans and taste the samples. In the end, we check for defective (有瑕疵的) beans.” Mubarik Abaoli is a lab worker.He says that testing is a very difficult and long process. “We select out the defects by hand. And we select out the defect according to the defect types.”
Ethiopia has got a lot of money by exporting coffee to more than 120 countries. The country has an export revenue (税收) of more than 840 million a year. But not all the best coffee leaves Ethiopia. Forty percent of the coffee grown in the country stays there. It remains an important part of everyday life at work, at home and at ceremonies.

【推荐1】Experts believe the best time to teach kids language skills is when they are babies. Actually the task is easily done with parents reading or talking to their babies. However, that is impossible when kids are born deaf.
In that case, parents either have to quickly become adept at sign language or risk the child facing learning delays in the future. Now, a lovely blue-eyed robot, a human avatar(用户头像), and some high-tech neuroscience(神经科学)may help parents with this important developmental task.
The Robot Avatar Thermal-Enhanced system, or RAVE, is the creation of a team led by Petitto, a scientist at Gallaudet University. The learning begins when the robot’s thermal(热力的)camera, which is focused on the baby’s face, senses small changes in his body temperature, which is associated with awareness. This, combined with the baby’s facial expression, causes the robot to turn its head and guide the baby’s attention to a computer screen.
Here, a human avatar starts to communicate with the baby much like a parent would. For example, if the baby points towards the screen, the avatar might respond, “Are you pointing to me?” and follow that up with a fairy tale, or some necessary social communication, all in sign language. The “conversation” continues until the kid loses interest.
The team, who have been testing the system for three years, found that babies began to move their hands in a way similar to sign language after interacting with RAVE for just a few minutes. Petitto says natural language, whether communicated through speech or sign, starts the same parts of the brain and believes the movement proves the babies are learning the key parts of communication.

【推荐2】From Marie Tussaud’s Chamber of Horrors to Disneyland’s Haunted Mansion (鬼屋) to horror-themed escape rooms, haunted house attractions have terrified and delighted audiences around the world for more than 200 years.
These attractions turn out to be good places to study fear. They help scientists understand the body’s response to fright and how we perceive some situations as enjoyably thrilling and others as truly terrible. One surprising finding: having friends close at hand in a haunted house might make you more jumpy, not less so.
Psychologist and study co-author Sarah Tashjian, who is now at the University of Melbourne, and her team conducted their research with 156 adults, who each wore a wireless wrist sensor during their visit. The sensor measured skin responses linked to the body’s reactions to stress and other situations. When the sensor picked up, for example, greater skin conductance — that is, the degree to which the skin can transmit an electric current — that was a sign that the body was more aroused and ready for fight or flight. In addition to this measure, people reported their expected fear (on a scale of 1 to 10) before entering the haunted house and their experienced fear (on the same scale) after completing the haunt.
The scientists found that people who reported greater fear also showed heightened skin responses. Being with friends, Tashjian and her colleagues further found, increased physiological arousal during the experience, which was linked to stronger feelings of fright. In fact, the fear response was actually weaker when people went through the house in the presence of strangers.
Other investigators have used haunted houses to understand how fear and enjoyment can coexist. In a 2020 study led by Marc Malmdorf Andersen, a member of the Recreational Fear Lab at Aarhus University in Denmark, scientists joined forces with Dystopia Haunted House. The Danish attraction includes such terrifying experiences as being chased by “Mr. Piggy”, a large, chain-saw-wielding man wearing a bloody butcher’s apron and pig mask. People between the ages of 12 and 57 were video recorded at peak moments during the attraction, wore heart-rate monitors throughout and reported on their experience. People’s fright was tied to large-scale heart-rate fluctuations; their enjoyment was linked to small-scale ones. The results suggest that fear and enjoyment can happen together when physiological arousal is balanced “just right”.

【推荐3】Many of us think, wrongly, that the moon doesn’t change. For example, the Tang Dynasty poet Zhang Ruoxu once wrote that “Generations have come and passed away; From year to year the moons took alike, old and new.”
However, a new study published in the journal Nature Geoscience shows that the moon is in fact slowly shrinking over time. For the study, a group of US scientists examined and analyzed thousands of photographs taken by the NASA orbiter Lunar Reconnaissance Orbiter Camera (月球勘测轨道飞行器照相机) . They found that there were lots of faults (断层) on the surface of the moon. These faults were formed by recent movement on the moon.
According to NASA, the moon is made up of pieces of rocks with a hot core (核) .The moon continued to expand as it was born. But in this process, it released energy and cooled down. Then it began to shrink, in a way comparable to the shrinking of a grape into a raisin (葡萄干) . Over the past several hundred million years, it has become 46 meters “skinnier”. But due to its hard and rocky crust (外壳) . the moon’s surface continues to push up, “Some of these quakes can be fairly strong around five on the Richter scale (里氏震级 ) ,” said Thomas Watters, a senior scientist at the Smithsonian’s National Air and Space Museum in the US.
But does that mean the moon is a dangerous place that human shouldn’t try to explore and live on in the future? Maybe not, reported the Telegraph, “This isn’t anything to worry about. The moon may be shrinking, but not by much. It’s not going anywhere,” Watters comforted us.
The new discovery proves that the idea that the moon is a dead, boring place is wrong. “We have been to the moon and we’ve done some great science, but there is still a lot we don’t know. The moon is shrinking — we didn’t really realize that until recently. It’s a much more active and interesting place than we thought and we should explore that,” NASA scientist Nathan Williams said.

【推荐1】At first glance, the business world is no place for young women. as my cofounders and I have been told on many occasions. In spite of this pessimistic view of women's opportunity in business, We three college-age girl with zero experience in business started off with a highly ambitious goal: to start a seaweed farm in North Carolina, and grow as much seaweed as possible to help reduce carbon emissions（排放）and nutrient pollution from agricultural sources.
In the beginning, our ideas were either ignored or scoffed by the researchers from whom we sought help and advice. But we carried on with our research-if others wouldn`t provide us answers, we weren't afraid to try to work them out ourselves. We discovered which species could grow in warmer waters, and we'd identified potential markets into which we planned to sell the product. We've spent the last two years setting up the first seaweed farm in NC, applying for a patent（专利）and competing with five final teams in front of the United Nations for $ 1million.
Despite all of our efforts, many industry experts remained unwilling to take us seriously. But as often happens in business, the same characteristics we were ignored for were, in reality, our biggest competitive advantage. Our age gave us the strength to bounce back from failure, and our background as environmental scientists, rather than businesswomen, helped us find new marketing opportunities. For every 10 farmers who claimed nobody would ever want to feed their cows seaweed, we found one who was interested. For every 15 cosmetics producers who refused to answer our cold calls, we stuck to the one with an interesting idea for a seaweed lotion.
Over the course of our early business development efforts, we have had access to a wealth of resources, programs, and individuals who work constantly to help us succeed. By staying focused on bringing our ideas to light, our team has demonstrated that entrepreneurship（创业）is exactly the right place for the hopeful.

【推荐1】Small talk – the likes of “What do you have there? Popcorn?” or “The weather today is beautiful, isn’t it?” – is meaningless and a waste of time, according to some people. But scientists believe that it is actually more useful than it may appear to be.
One example comes when you are on a train or a plane. The thought of talking to the stranger sitting beside you can be scary, because you know the conversation is sure to be awkward. But a study by the University of Chicago in the US found that people who chat to strangers enjoy a better ride than those who sit in silence or occupy themselves with their phones.
In the study, researchers asked people at Chicago train stations to start conversations with fellow travelers. Most of them refused to do so at first because they expected not to get a friendly answer. But the result turned out to be just the opposite – most strangers were not only willing to be talked to, but also pleasant to talk to.
“Human beings are social animals,” Nicholas Epley, one of the lead researchers, told Live Science. “Other people are people, too. And it turns out that they’d like to get to know you.”
Apart from making you happier, small talk with strangers can also help you feel connected to your surroundings. Previous studies found that when people are frequently smiled at, made eye contact with and spoken to at coffee shops, they tend to have a stronger sense of belonging instead of feeling like they are being ignored and left out.
And if you are already comfortable enough to make small talk with strangers, you should try to develop it into something “bigger”.
A 2010 study proved that having a deep and meaningful conversation gives you even more happiness than small talk. Participants in the study – 79 college students – reported after the four-day experiment that they were much happier when they had a third as much small talk and twice as many in-depth conversations.
But deep conversations can start with small talk, can’t they? So the first step is to start talking, no matter how casual the topic is. And who knows, maybe an opening line as simple as “I like your hat” could lead to a serious conversation in which you learn something new from a stranger.
1. What is the reason for the result of the study by the University of Chicago, according to Nicholas Epley?| A．Most people are nice to strangers. |
| B．People are naturally curious about others. |
| C．People are afraid of loneliness or boredom. |
| D．People try to show their good side to strangers. |
| A．Wasting less time. | B．Getting rid of useless contacts. |
| C．Coping with smart phone addiction. | D．Feeling like you are a part of your surroundings. |

【推荐2】A food additive (添加剂) is any substance that is added to food. Many people are put off by the idea of “chemicals in food.” The truth is that all food is made up of chemicals. Natural substances (物质)like milk, as well as man-made ones like drinks on sale in the market, can be described by chemical formulas. Some chemical substances are indeed harmful, but a person who refused to consume any chemicals would find nothing to eat.
The things we eat can be divided into natural and man-made substances. Some people feel that only natural foods are healthy and that all man-made ingredients are to be avoided. But many natural chemicals, found in plants and animals, are harmful when eaten, and some laboratory-made substances increase the nutritional value of food. Other chemicals have natural and man-made forms that are exactly alike: vitamin C is vitamin C, whether it comes from a test tube or from an orange. Like “chemical”, “man-made” doesn’t necessarily mean “not fit to eat”.
Food additives are used for many reasons. We add sugar and salt and other things to foods we prepare at home to make them taste better. Food producers have developed a range of additives that stabilize, thicken, harden, keep wet, keep firm, or improve the appearance of their products.
Additives can make food more convenient or nutritious, give it a longer shelf life, and make it more attractive to the consumer, thus increasing the sales and profits of the producers.
Food additives are presently the centre of a storm of serious argument. Food producers have been known to use additives that have not been proved safe; some substances in common use have been proved unsafe and have been taken off the market. Many people feel there’s a risk of eating food to which anything has been added. But food additives are now regulated by the FDA of the federal government, and new additives will go through strict testing before they can be placed on the market. For most people, the chances of developing serious side effects from the long-term use of presently approved (批准) food additives are very small.
1. From the passage we can learn that ______ .| A．it is right to refuse chemicals in food |
| B．all foods have chemical substances |
| C．food additives are harmful to our health |
| D．natural foods are much safer than man-made ones |
| A．Foods without additives can keep a much longer shelf life. |
| B．Foods with more additives have higher nutritional value. |
| C．To ensure food safety, the FDA will stop food additives. |

【推荐3】That warm day was the only day of the week without rain.I opened the door, took a seat and began to enjoy the wonderful sunshine.Suddenly, I noticed that the house near mine had been sold.An elderly lady was in front of the door, with some beautiful flowers beside her. I walked to her. She looked to be in her early eighties and had the prettiest white hair.
“Hi!My name is Karmen,” I said smiling brightly at the old lady. She smiled back and said, “Hello,Karmen.I’m Kitty.” Her voice was very strong for someone at her age. Later, I learned that she was alone and had no family or relatives to help her. From that day on, I often visited her and helped her with her housework and sometimes she gave me some delicious food. A year passed, and I considered her to be one of my best friends.
One day, I walked over for my morning visit and knocked on the door, but there was no answer. I knocked again, and she still didn’t turn up. So I let myself in, using the key she had given me. I checked her living room and then her kitchen. I finally went into her bedroom, and she was lying peacefully on her bed. Beside her there were two notes. One was her will (遗嘱), which said all that she had would be given to me. The other was a thank-you note. I went to her bedside and cried sadly.
Though several years has gone by, I still miss her deeply. Whenever I look at the beautiful flowers in front of her house, I remember the wonderful friendship we had.
