More than 140 sign languages are used today, primarily by deaf communities around the world. Like spoken languages, each sign language has its own grammar, vocabulary and other special features. For example, American Sign Language is unintelligible(无法了解的)to British Sign language. In fact, American Sign language has more in common with French Sign Language, largely because French educators played a key role in helping get deaf schools founded in the United States during the 19th century.
There haven’t been a lot of comparisons of sign languages. University of Texas, Austin linguist Justin Powers and his colleagues aim to address that information gap. In order to study the question of sign language evolution, they first collected a database of manual alphabets from dozens of different sign languages around the world. So a manual alpha-bet is kind of a subsystem within a sign language that is used to represent a written language. And there’s a hand shape that corresponds to each letter.
To uncover relationships between the alphabets% the researchers used the same methods that biologists use to figure out relationships between different species, based on their DNA. The methods grouped sign languages in this study into five main European lineages(谱系). And those were Austrian origin, British origin, French origin, Spanish and Swedish. Power says manual alphabets from Austria, France and Spain could date back to one-handed manual alphabets from 16th- and 17th-century Spain. But each of those lineages evolved independently of each other.
The study also confirmed the French origins of American Sign Language and those of other countries, including Mexico, Brazil and the Netherlands. Surprisingly, the Austrian manual alphabet influenced sign languages as far away as Russia. But while this lineage has largely died out, remains of it live on in Icelandic Sign language today.
Power says future research comparing the vocabularies of different sign languages could provide even more clues about how they’ve changed over time. Understanding how sign languages evolve would tell us a lot about the way that language, in general, evolves.

【推荐1】The guy who tried to edit English
The English vocabulary is not only huge, but also full of words that mean practically(几乎) the same thing- Get, obtain, acquire. Shine, gleam, glow, sparkle.
That was the thinking of a British writer named C. K. Ogden, who in the 1930s proposed (提议) a new form of English with a vocabulary of just 850 words. He called the project Basic English
Ogden arrived at his 850-word list through experimentation, rephrasing texts over and over until he was satisfied. The words he finally included were not necessarily the shortest or most concrete.
Winston Churchill was a fan of the concept as a way to get foreigners to speak English, and he encouraged the BBC to use it.
A.Do we really need them all? |
B.How many words are there in English? |
C.Ogden himself didn't actually use Basic English. |
D.Plenty of seemingly basic words did not make the list at all. |
E.He also tried to persuade President Franklin Roosevelt to promote it. |
F.He believed it would make the language more efficient and easier to learn. |
G.Despite attention from world leaders, Basic English never got very far off the drawing board. |
【推荐2】Recently I read Nineteen Eighty-Four, a novel by George Orwell set in a state where even the language they use is controlled. Adjectives are forbidden and instead they use phrases such as ‘ungood’, ‘plus good’ and ‘double plus good’ to express emotions. As I first read this I thought how impossible it would be in our society to have such vocabulary. However, the more I thought about it, the more I realised in its own way it’s already happening. I type messages to my friends and alongside each is the emoji. I often use them to emphasise something, or to not seem too serious, or because this specific GIF conveys my emotions much better than I ever could using just words. And I wonder, with our excessive use of emojis, are we losing the beauty and diversity of our vocabulary?
English has the largest vocabulary in the world, with over one million words, but who’s to say what it’ll be like in the future? Perhaps we will have a shorter language, full of saying ‘cry face’ if something sad happens or using abbreviations (缩写) like LOL (laugh out loud) or BRB (be right back) instead of saying the full phrase. So does this mean our vocabulary will shrink? Is it the start of an exciting new era? Will they look back on us in the future and say this is where it all began – the new language? Or is this a classic case of the older generations saying, ‘Things weren’t like that when I was younger. We didn’t use emoticons to show our emotions’?
Yet when you look back over time, the power of image has always been there. Even in the prehistoric era they used imagery to communicate, and what’s even more incredible is that we are able to analyse those drawings and understand the meaning of them thousands of years later. Pictures have the ability to transcend time and language. Images, be it cave paintings or emojis, allow us to convey a message that’s not restrictive but rather universal.

【推荐3】In 1947, the province Bengal of Pakistan was divided into two parts: the western part became India and the eastern part is known as East Bengal which was later known as East Pakistan. At that time there were many economic, social and cultural problems. In 1948, when government announced Urdu as the national language, it caused the protest among the Bengali speaking majority of Pakistan. The protest got out of control and ended with the death of four protestors of the University of Dhaka who were shot by the police on 21st February, 1952. The students’ deaths during the fight for their mother language are now remembered as The International Mother Language Day (IMLD).
Each year on Feb 21, UNESCO holds the event to draw attention to the disappearance of the world’s languages: dozens of them are disappearing each year. What happens when a language dies out? Something huge is lost -- not just sounds and marks but the way that people make sense of the world and communicate with each other. And it is through language that we have culture and tradition. Kill a language and all this is killed too.
Through IMLD, more people are becoming more aware of the destruction of linguistic (语言的) diversity in modern times and trying to stop it. The Myaamia Project is a kind of effort. This is an attempt to revive (复兴) the language spoken by the Miami and Illinois tribes (部落) of the US. Project members work to encourage people to study and communicate with this language, which formally died out in the 1960s.
This is why we should remember the wise words of Nelson Mandela: “If you talk to a man in a language he understands, that goes to his head. If you talk to a man in his own language, that goes to his heart.”

The most common use of intelligence test scores is to tell in advance degree of academic success. Such scores are used in some communities as bases for admitting able children to schools at ages younger than normal, and they are very generally used to determine admissions to schools beyond public secondary school. Another use common in elementary schools involves comparing such scores with performances in various subjects to find out children who are working below capacity.
The greatest problem in using intelligence tests for the purpose of prediction is that no dependable criterion of their accuracy exists. The ideal criteria would be objective and reliable achievement tests following instructions in each subject, but there are few such tests, especially at the college level. Studies have shown that correlations(相关性) between intelligence tests and achievement tests in various subjects through secondary school range roughly from 0.5 to 0.8. Such correlations are fairly high, but they do not suggest anywhere near complete agreement.
At the college level there are two major tests used as criteria of admission. By far the more important is the College Entrance Examination, constructed by the Educational Testing Service authorized by the College Entrance Examination Board. These tests are returned to the Educational Testing Service for scoring, and the results are then made available to the various colleges authorized by the students to receive them. The second test of this type is the American College Test, which operates in essentially the same fashion.
Both tests constitute(组成) measures of certain skills, abilities, and knowledge that have been found to be related to success in college. Their correlations with academic success are limited for three outstanding reasons. First, measures of achievement in college are themselves perhaps no more reliable than those in elementary and secondary schools. Second, intellectual factors do not alone determine academic success, especially at the college level. Many students drop out of schools because they are inadequately motivated or because they dislike the instructional programme. Third, correlations are lowered because the use of such tests for denying admission to some students means that the range of scores for those admitted is restricted, and such restrictions tend to reduce correlations.

“If you try to kill a bat, you are more likely to get bitten,” said Joy O’Keefe, assistant professor of biology and director of Indiana State University’s Centre for Bat Research, Outreach and Conservation. “Most bats people find in their houses are healthy and are not going to bite them and give them rabies.” But they could be a federally endangered species, such as the Indiana Bat, which is found in this area.
So if you spot a bat in your home or office, don’t kill it or touch it with bare hands, O’Keefe said. Instead, put on a pair of heavy gloves and gently move it into a box or bucket. Once contained, the bat can be removed outside.
“If it’s a healthy bat, it’ll fly away eventually,” O’Keefe said. “If it doesn’t move or seem to be healthy, you can take it to the health department to be tested.”
This is the time of year when bats move from their summer resting sites to their winter resting sites, O’Keefe said.
“We get calls every year during the first month of school year from people finding bats in the university’s buildings,” said O’Keefe.
Bats are a great help to people, as every night they can eat up to their entire body weight of insects. Bats, however, are facing great threats from epidemics(流行性疾病), habitat destruction and other things.
“The best way the average person can help bats is by understanding them and by telling other people how awesome bats are and what bats do for us,” O’ Keefe said. “Hopefully, it will make people think that if there’s a bat in their house, they should try to get it out but not kill it. That would be really positive for bats—to not have people be one of their major threats.”

【推荐3】Behavioral ecologist Diane Colombelli-Négrel was wiring the nests of superb fairy-wrens (细尾鹩莺) to record the birds’ sounds when she noticed something odd. Mothers sang while hatching (孵化) their eggs, even though keeping quiet would avoid attracting predators (捕食者). That early discovery “was a bit of an accident”, says Colombelli-Négrel, of Flinders University in Adelaide, Australia. It made her wonder: Could the baby birds be learning sounds, or even songs, before hatching?
Scientists have long thought about how early in development individuals learn to perceive distinct sounds. It's known that humans learn to recognize their mother’s voice from the womb (子宫) . For birds such as superb fairy-wrens, which perfect their songs with parental teaching, it was thought that sound perception (认知) began after hatching. But when it became obvious that mother birds were intentionally singing to their eggs, “We knew we were on to something,” says Sonia Kleindorfer, a bird ecologist at the University of Vienna.
Colombelli-Négrel, Kleindorfer and a colleague reported in 2014 that superb fairy-wrens learn to distinguish between sounds of their own species and others while still in their eggs. In a new study, that ability appears to extend to at least four more bird species.
In birds and humans, a drop in the embryonic (胚胎的) heart rate suggests attention to a stimulus (刺激). In the scientists’ earlier work, unhatched fairy-wrens’ heart rates slowed in response to repeated sounds of their own species, but not others.
To investigate whether this phenomenon is more widespread among birds, the team also turned its attention to the embryonic heartbeats of other bird species. The team measured the heart rates of 109 unhatched chicks before, during and after exposure to playbacks of songs from their own species or others. Then the scientists looked at whether 138 embryos stopped paying attention or became habituated to, repeated sounds of unfamiliar individuals of their own species singing. This habituation. measured by the heart rate returning to normal, would imply learning had occurred.
To the team’s surprises all of the eggs showed a slowed heart rate in response to their species’ sounds and showed habituation. That finding suggests that these unhatched birds learned to perceive the sounds of their species’ songs.
The scientists don’t know why some bird species, whose calls are genetically determined, not taught by teachers, have this ability before birth. The team hopes to study prenatal (产前的) sound perception in more bird species.

【推荐1】A cat with an accent sounds like a character in children’s tale, but Swedish scientists are trying to figure out if domestic cats actually do have different “dialects” based on their geographical location. They also want to understand if the owner’s voice might have a role to play in the way cats’ meow(猫). If they’re successful, the team of scientists from Lund University. hope to put together a “dictionary” of cat sounds.
The project will be carried out over the next five years. SchÖtz explained that she and her team will use phonetic(语音)analysis to compare cat sounds from two parts of Sweden-Stockholm and Lund-with different human dialects, and figure out if the cats from these regions also have different dialects. They will focus on tune, voice, and speaking style in the human speech that is addressed to cats, and also cat sounds that are addressed to humans.
While it all sounds rather fanciful, the main idea behind the project is to improve the human-cat relationship. Since their domestication(驯化)about 10,000 years ago, cats and humans have learned to “talk” through audio(声音的)and visual signals. Even today, wild cats have no need for meowing in adulthood, while domestic ones continue to meow as a way of communicating with humans. And by understanding more about this communication, SchÖtz and her team hope to influence the way cats are treated in animal hospitals, shelters, and care homes.
The team will record voices of about 30 to 50 cats in different situations, for example when they want access to desired locations, when they are content, friendly, happy, hungry, annoyed, or even angry-and try to identify any differences in their phonetic patterns. They want to know if cats prefer pet-directed speech or prefer to be spoken to like human adults.
The project is yet to begin officially, but the researchers have already started testing their equipment and techniques by recording a few cats’ meowings. And they’ve already made a few interesting observations. In one of the recordings, they noticed that when a cat is begging for food its meows rise slowly. But the opposite happens when the cat is unhappy. By the year 2021, SchÖtz and her team hope to have entirely broken the cats’ code by interpreting all their meowings.
1. Carrying out the research, Swedish Scientists will mainly investigate ______.A.how cats vary the melody of meows | B.how cats communicate with their owners |
C.how cats meow with a funny mood | D.how cats are treated around the world |
A.find out where the cats live | B.understand the cats’ lifestyle |

C.Unconcerned. | D.Skeptical. |
Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material aspects, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the simple elements(要素)rather than in the complex ones; and in elements that are acceptable to the culture rather than in strange ones.
Besides, social change is easier if it is gradual. For example, it comes more readily in human relations on a continuous scale rather than one with a sharp division. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities, because of the sharp difference in appearance between them and their white fellows.

【推荐3】Faces, like fingerprints, are unique. Did you ever wonder how it is possible for us to recognize people? Even a skilled writer probably could not describe all the features that make one face different from another. Yet a very young child or even an animal, such as a pigeon can learn to recognize faces. We all take this ability for granted.
We also tell people apart by how they behave. When we talk about someone’s personality, we mean the ways in which he or she acts, speaks, thinks and feels that make that individual different from others.
Like the human face, human personality is very complex. But describing someone’s personality in words is somewhat easier than describing his face. If you were asked to describe what a “nice face” looked like, you probably would have a difficult time doing so. But if you were asked to describe a “nice person”, you might begin to think about someone who was kind, considerate, friendly, warm, and so forth.
There are many words to describe how a person thinks, feels and acts. Gordon Ports, an American psychologist, found nearly 18,000 English words characterizing differences in people’s behavior. And many of us use this information as a basis for describing, or typing, his personality. Book worms, conservatives, military types people are described with such terms.
People have always tried to “type” each other. Actors in early Greek drama wore masks to show the audience whether they played the villain’s or the hero’s role. In fact, the words “person” and “personality” come from the Latin word “persona”, meaning “mask”. Today, most television and movie actors do not wear masks. But we can easily tell the “good guys” from the “bad guys” because the two types differ in appearance as well as in actions.
1. Which of the following statements is NOT true?A.People may have different personalities. |
