To call someone bird-brained in English means you think that person is silly or stupid.
But will this description soon disappear from use in the recent research? It seems English may have been unfair in association bird’s brains with stupidity.
In an attempt to find out how different creatures see the world，psychologists at Brown University in the USA have been comparing the behaviour of birds and humans.One experiment has involved teaching pigeons to recognize letters of the English alphabet.The birds study in “classrooms”，which are boxes equipped with a computer.After about four days of studying a particular letter, the pigeon has to pick out that letter from several displayed on the computer screen.Three male pigeons have learned to distinguish all twenty-six letters of the alphabet in this way.
A computer record of the birds7 four-month study period has shown surprising similarities between the pigeons’ and human performance.Pigeons and people find the same letters easy, or hard，to tell apart.For example, 92 percent of the time the pigeons could tell the letter D from the letter Z.But when faced with U and V ( often confused by English children)，the pigeons were right only 34 percent of the time.
The results of the experiments so far have led psychologists (心理学家）to conclude that pigeons and humans observe things in similar ways.This suggests that there is something basic about the recognition process.If scientists could only discover just what this recognition process is, it could be very useful for computer designers.The disadvantage of a present computer is that it can only do what a human being has programmed it to do and the programmer must give the computer precise，logical instructions.Maybe in the future，though，computers will be able to think like human beings.

【推荐1】Next fall, when you see geese heading south for the winter, flying along in a V-formation (阵式), you might consider what science has discovered as to why they fly that way.
As each bird moves its wings, it creates uplift for the bird immediately following. By flying in a V-formation the whole group adds at least 71% greater flying range than if each bird flew on its own. People who share a common direction and sense of community can get where they are going more quickly and easily because they are traveling on the thrust (用力推) of one another.
When a goose falls out of its formation, it suddenly feels the drag and resistance of trying to go it alone and quickly gets back into formation to take advantage of the lifting power of the bird in front. If we have the same sense as a goose, we will also stay in the formation with those who are headed the same way we are.
When the head goose gets tired, it rotates (旋转) back in the wing and another goose flies to the point. It is reasonable to take turns doing demanding jobs—with people or with geese flying south. Geese honk (雁鸣) from behind to encourage those to keep up their speed. What do we say when we honk from behind?
Finally, and this is important—when a goose gets sick or is wounded by gunshots, and falls out of its formation, two other geese fall out with that goose and follow it down to lend help and protection. They stay with the fallen goose until it is able to fly or until it dies, and only then do they fly out on their own, or with another formation to catch up with their group. If we have the sense of a goose, we will stand by each other like that.
1. Every goose wants to stay in the V formation in order to ________.| A．get an uplift from each other | B．make a beautiful sign in the sky |
| C．escape from this group | D．just make fun |
| A．geese’s behaviors seem very meaningful but foolish |
| B．what the geese do should be adopted by our human beings |
| C．our human being always hate this way |
| D．geese are our people’s good friends |
| A．We are crying when we fall behind. |
| B．We are ashamed of our human’s behavior and really did worse at this aspect. |

【推荐2】When thinking about ancient and mysterious animals, dinosaurs may first come to mind. But a new study shows octopuses (章鱼) appeared on Earth before the era of dinosaurs.
Scientists have found an ancestor of octopuses — a 330-million-year-old fossil (化石) unearthed in Montana, United States. The research concluded the ancient creature lived millions of years earlier than previously believed.
Apart from the impressive age, the octopus is also one of the oddest creatures in existence. Their mouths are in their armpits (腋窝); they have three hearts; they have blue blood. And the grace? I mean, who has grace like this?” Sy Montgomery, a German-born naturalist, told CBS News.
Of all the octopus’ oddities, perhaps the most extraordinary one is that the octopus has one large central brain, and eight mini-brains, one in each arm. As a result, the arms can solve the problem of how to open a shellfish while their owners are busy doing something else, like checking out a cave for more edible goodies (可食用的东西), according to Smithsonian magazine.
The ancient creature is also well-known for its disguises. The octopus can change its shape, colors, patterns, even the texture (纹理) of its skin. It can transform itself to look like seaweed in just the blink of an eye. This ability is called dynamic camouflage (动态伪装).
“I would argue that dynamic camouflage is a form of intelligence,” Roger Hanlon, a top octopus researcher said in a TED Talk.
The camouflage may look like a reflex (本能反应), but it’s not. It doesn’t just happen instinctively. They actually think and decide how to best camouflage themselves. “This is a decision-making process,” Hanlon said. “They’re not only taking into account the surroundings for camouflage, but also an approaching threat. And they’re calculating all the time about what they’re going to do next.”
1. What does the fossil unearthed imply?| A．Octopuses and dinosaurs have a common ancestor. |

【推荐3】The British are famous as animal lovers, and in a nation of about 60 million people, there are about 27 million pets! The most popular pets are dogs and cats.
Many British people say that the main reason they have a pet is to keep them company (陪伴他们). According to a recent report, 60% of people who live on their own have a pet as company. A lot of pet owners treat their pet just like one of the family. Many cat owners make holes in their doors so their cats can come and go as they please. Dog owners spend a lot of time walking their dogs.
Another reason to own a pet is for protection, especially dogs. Most thieves would think twice about breaking into (闯入) a house if they could hear a large dog barking inside. Some people choose their pets because of their beauty. The most beautiful animals can win prizes at pet shows!
In the UK, some pet owners think that nothing is too good for their animal! Some people take their pet to the animal doctor more often than they visit their own doctor. They might even take a day off work to care for a pet when it is sick. Many people talk to their pets, and some talk to them over the telephone. And of course, they mustn’t forget to celebrate the animal’s birthday!

【推荐1】A century ago, millions of Quino checkerspot butterflies flew above Southern California. Each about the size of a paperclip, the Quinos hatched in great numbers each spring.
Toward the end of the twentieth century, however, the development of farms and cities dramatically reduced the butterfly’s habitat. By 1997, the population of the Quinos had declined to a tiny amount of its historical numbers.
The Quino’s situation continued to worsen. Wildfires burned much of its habitat, and temperatures were getting warmer and drier, making the environment more difficult to the butterfly’s host plant called the dwarf plantain.
Scientists knew that Quino caterpillars relied on the dwarf plantain as a food source. Each spring, the adult female butterflies laid eggs on dwarf plantains. When the caterpillars hatched, they fed on the plantain leaves. However, in the hot, dry summer, the plantains died off. The caterpillars responded by entering a state called diapause. Then, when normal winter rains came and the plantains’ flowers came out again, the caterpillars came back to life and started eating. Once they’d grown large enough, the caterpillars formed pupae and emerged as adult butterflies. This strategy worked well in most years, but as average temperatures rose and rainfall decreased, the caterpillars weren’t getting sufficient food, and fewer developed into butterflies.
Because the area where they lived was surrounded by developed cities and desert landscapes, the Quinos had limited options. They took off anyway, flying eastward into the hills. They landed in mountainous open spaces east of Los Angeles and San Diego. They found no dwarf plantains there. The females began laying their eggs on the leaves of other plants, primarily the Collinsia concolor. These plants remained green longer into the summer months. When the caterpillars Quinos survived, and their numbers grew in their new home.
Scientists were surprised when they began encounter innumerous Qunios in the eastern hills. They were cheered to learn that these small insects had adapted to changing conditions. The Quinos demonstrated the toughness needed to survive by finding not only a new habitat, but a new food source, too.
Meanwhile, scientists had been raising Quino caterpillars in a lab and released hundreds of caterpillars into protected areas around San Diego. Between the efforts of scientists and the butterflies’ own actions, more of those colorfully checkered wings may soon be seen fluttering above the Southern California skies.

【推荐2】A recent study in Japan has showed that a wearable soft robot, named Reliebo, can improve the experience of patients in medical treatments, such as injections (注射) and other unpleasant treatments. The goal of the robot is to help ease pain and defend people against anxiety. The study, led by researchers at the University of Tsukuba, was inspired in part by the numerous needles (针) people had to put up with while being vaccinated against COVID-19. Some people felt an intense dislike for these needles, which led to fewer people getting vaccinated.
The robot is soft and covered in fur. It contains small airbags internally that inflate (膨胀) in response to hand movement. Participants in the study who wore the robot while subjected to a medium heat stimulation, experienced less pain in the test than those who did not wear the robot.
The research team checked the effectiveness of the wearable robot while being handled by participants under certain conditions, based on the clenching (紧握) of the hand. The team placed painful heat stimulation on the other arm that was not holding the robot. They then measured cortisol (皮质醇) levels from the participants’ saliva (唾液) samples, suggesting levels of stress hormones. The pain felt by the patients was given specific ratings and was also recorded using an assessment table. The people in the study were given a survey test to assess their fear of injections before and after the experiment with the wearable robot was completed.
The study proved that a wearable-informed robot may serve as a promising tool to ease the experience of patients who were receiving injections. The research team hopes to use this study to advance the robot for use during painful situations, such as getting medical shots or similar conditions.
1. What is the function of the robot?| A．To make doctors inject accurately. |

【推荐3】Modern Europeans came from three major groups of ancient humans, not two as was thought before, according to a study published on Wednesday.
Until now, it was widely believed that Europeans evolved (进化) from two prehistoric groups. One was early farmers who moved into Europe from the Middle East about 7,500 years ago. The other was local hunter-gatherers who had lived in Europe for more than 40,000 years.
But a new study in the journal Nature says there was a third group in the mix: people from northern Eurasia. They lived in today’s Russia and northern Asia. The finding means that northern Eurasians contributed to the human genes (基因) both in Europe and North America.
Their influence on the Americas has been proved by previous studies which showed that they reached modern-day Alaska in the US more than 15,000 years ago. They crossed an “ice bridge” that connected islands in the Bering Strait, a narrow passage of water between Asia and North America, at the time.
Researchers collected genetic information in nine ancient humans’ bones. The remains were found in Sweden, Luxembourg and Germany. They were one farmer from about 7,000 years ago and eight hunter-gatherers who lived about 8,000 years ago, before the coming of agriculture.
The researchers compared the information with the gene pool of 2,345 present-day people living all over the world. They found almost all Europeans have ancestry from all three of those ancient groups.
The ancient northern Eurasians contributed up to 20% of the genetics of Europeans, although this was the smallest percentage among the three ancestral groups.
People in northern Europe, especially the Baltic states, have the highest percentage of western European hunter-gatherer ancestry. Up to 50% of the DNA of Lithuanians of northeast Europe comes from this group.
Southern Europeans had more of their genetic ancestry from the ancient farmers. Up to 90% of the DNA of Sardinians of Italy can be traced back to (追溯到) these early European immigrants.
Looking ahead, the researchers plan to find out when the ancient northern Eurasians arrived in Europe.
1. Ancient people from northern Eurasia _____.| A．brought agriculture into Europe | B．reached Europe about 7,000 years ago |

【推荐1】A team of Japanese scientists has discovered genes that enable rice to survive high water, providing hope for better rice production in lowland areas that are affected by flooding.
The genes, called SNORKEL genes, help rice grow longer stems to deal with higher water levels. Deepwater rice generally produces low-yield rice plants. But the researchers report they have succeeded in introducing the genes to rice varieties that are higher-yield.
According to the report, as water levels rise, accumulation of the plant hormone（激素）makes the SNORKEL genes stat working, making stem growth more rapid. When the researchers introduced the genes into rice that does not normally survive in deep water, they were able to rescue the plants from drowning.
Motoyuki Ashikari, who headed the project, aid his team is hoping to use the gene on long grain rice widely used in Southeast Asia to help stabilize production in flood areas where rice with the food-resistant gene is low in production--about one-third to one-quarter that of regular rice.
"Scientifically the gene that we found is are but clear proof of a biological ability to adapt to a difficult environment, " he said. "It's a genetic strategy specifically to survive flooding. "
High water levels in rice field can be a serious problem. In some areas, rains can cause water levels to rise dangerously high during the growing season and flash flooding can fully submerge plants for days or even weeks.
Rice is a main food for billions. and while productivity has increased dramatically since the 1960s, yields must be doubled to meet projected requirements by 2050. More than 30 percent of Asian and 40 percent of African rice land is either lowland field or deep water field.
Laurentius of Utrecht University said the study is significant because high-yield rice varieties cannot survive extremes of foods. "The introduction of these genes into high-yield varieties, using advanced breeding strategies, promises to improve the quality and quantity of rice, "he said.
1. What is the main character of SNORKEL genes?| A．They prevent rice from being attacked by various diseases. |
| B．They help rice grow taller in highland regions. |
| C．They make rice grow tall enough to survive in deep water. |
| D．They make rice be ripe within a shorter time. |

【推荐2】Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.
The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling,and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels(分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
1. According to the passage, which of the following is increasingly dangerous to sea creatures?| A．The man-made noises. | B．The noises made by themselves. |
| C．The sound of earthquakes. | D．The sound of the ice-breaking. |
| A．Different places with different types of noises. |
| B．The very human ears sensitive to all types of noises. |
| C．The same noise measured differently on land and in the ocean. |

【推荐3】The way people decorate their homes can tell a lot about themselves. Obviously the way we decorate our homes is very personal. And while many of us have plenty of options, there are always people who go that little bit further. So, when it comes to minimalism (极简主义) and maximalism (极繁主义) , which one appeals to you more?
Minimalism was an art movement that started in the 1950s. Its basic principles come from a concept of less is more, reducing things to their most basic. Some people took that art style and used it as a way of living. Their houses are usually decorated in simple colors, often just black and white. For some, especially maximalists, it may seem a bit boring or depressing. However, living in this way is seen by many as more organized and practical.
Maximalism started in the 1970s. It embraces the core ideals that “more is more”. While minimalism centres around the principle of removing, if it’s easy to imagine that a maximalists’ home is piled with items—but that’s not the basic idea. It’s more about making the most of the area. Organized excess and bright colors combined with mixed patterns is what you will see in a home like this. For a minimalist, being used to more simple designs, it could be uneasy. But for those who embrace it, those things give a space personality.
The way you have your home is up to you! But, if you choose maximalism, you may need to prepare for a bit more dusting.
1. What may maximalists think of minimalists’ lifestyle?| A．Interesting. | B．Practical. | C．Amazing. | D．Dull. |

【推荐1】Experts are buried in their research in 3D printing food. Several 3D printers designed for food are now on the market. Anything that can be made into a soft wet mixture can be squeezed from a tube in a 3D printer. Instead of ink, these printers can use fruits, vegetables, proteins, sweets, and more. This makes for lots of combinations that can be healthy, delicious, and even artistic, which will be well received by people.
Most 3D printers don’t actually cook the food, at least not yet. Engineers at Columbia University’s Creative Machines Lab invented an oven (烤箱) that cooks 3D-printed pizza with laser beams (激光束). A special computer program controls the lasers, heating each part of the pizza to perfection. Unlike regular ovens, lasers can carefully cook each thin piece of 3D-printed food.
In the future, food can be made with a 3D printer to meet our needs. For example, a hospital could design meals to meet patients’ dietary needs. Vitamins, minerals, and even medicines can be mixed right in. A 3D printer can make food appealing. Foods that someone may not like might be more attractive after 3D printing. Maybe that food you dislike wouldn’t seem so bad if it looked like a castle!
The idea of 3D printed food may seem very modern. In fact, NASA (美国国家航空航天局) has been researching the topic for more than ten years. On a long travel, it’s important to have food that is easy to make, tastes good, and has the nutrients astronauts need to stay healthy. Printing food on demand may soon be into the space!

【推荐3】After disappearing for over 19 years, measles (麻疹) is making a comeback in America. Since January 2019, the disease has infected more than 700 people, mostly small children, and the number seems to be increasing daily.
Measles is an infectious disease that typically begins with a high fever, cough, runny nose, and red, watery eyes. Many people also lose their appetites and feel sleepy. About three to four days after the symptoms start, the person breaks out into a rash (皮疹) that begins on the face at the hairline and then spreads to the neck and the rest of the body.
In healthy people, the recovery, which takes between two to three weeks, starts soon after the rash begins. However, for about 40 percent of patients — mainly kids under the age of five or older adults — the disease often leads to pneumonia (肺炎), which, if left untreated, could result in death.
The recent outbreak is thought to have been caused by travelers picking up the virus in a country where the disease is still existing and exposing it to an unvaccinated (未接种的) community in the US. In New York, it was carried back by someone who had recently visited Israel, which is currently undergoing a significant measles, while in Washington, “patient zero” was infected by a type that is currently circulating in Europe.
To limit the spread of the disease before it gets out of hand, US health officials are attempting to educate communities with high rates of unvaccinated children. They are also urging adults to consult with their physicians and get injected if considered necessary by the doctor.
Hopefully, health officials worldwide will be able to convince parents that vaccinating their children will protect, not harm, them.
