Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.

    Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收缩) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.

    Sarah Garfinkel at the Brighton and Sussex Medical School said: “Our Study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”

The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, “The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see一and guide whether we see fear.”

To further understand this relationship, the scientists also used a brain scanner(扫描仪) to show how the brain influences the way the heart changes a person's feeling of fear.

“We have found an important mechanism by which the heart and brain ‘speak' to each other to change our feelings and reduce fear,” Dr Garfinkel said.

    “We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those who may be suffering from serious stress disorder.”

    For centuries people have hunted animals for food and pleasure.The invention of the gun made it so easy for humans to hunt that some animals were lolled by the thousands and even became extinct（绝种的）.This brings up some serious problems since breaks in the food chain upset the balance of nature.

    Large animals like tigers are being killed by the hundreds every year in India.The Royal Bengal tiger is the only type that exists in India and their number is greatly reduced every year because of poaching（偷猎）.The present number is about 2,000, all of which live in tiger reserves.Two hundred years ago the population was 23,000 or more.

    During the British rule of India,many of the so-called English gentlemen killed tigers for pleasure and to show their bravery.This seems stupid because killing an innocent（无辜的）creature with a gun is not a brave deed.

    Today the tiger skin is very popular.Rich people and fashion designers have no idea what they are doing. Competition between the rich to show off makes them blind to the serious effects.People persuade villagers to kill tigers to get money,and they do it because they are poor and need to feed their families.We must educate them,and the government should give them proper jobs to help solve this problem.

    The people to blame are those who buy animal products like ivories,furs,tiger bones for medicine and handbags made of animal skins.They must be put behind bars to stop this kind of trade.The earth is home for everyone on it. The trees,animals,birds,and fish of all kinds belong here as much as we do.Only we have the power to change their fate.

    Many people believe high heels(E)make women look good. It seems that the organisers of the Cannes Film Festival reportedly stopped women in low-heeled shoes from walking the red carpet. But all this charm comes at a cost, wearing heels over 10em high can damage your feel.

    A study by Hanseo University in South Korea suggests that continuous wearing makes women run the risk of getting hurt, and makes them easy to lose their balance, A total of 40 women who wear high heels at least three times a week took part in the study, The strength of their feet was measured regularly, researchers found that two of the four main muscles became stronger after a period of between one and three years, This created an imbalance in their feet, Dr Yong Seok Jee from Hanseo University says that the habit of wearing heels can result in feet out of shape, back pain and unhealthy walking patterns He suggests that women limit the use of these kinds of shoes and exercise their foot muscles properly.

    High heels are considered by some people to be female, but in fact the fashion started with men's feet. These shoes were a form of riding footwear, and were seen on the feet of 17th century Persian soldiers, Elizabeth Semmelhack of the Bata Shoe Museum in Toronto says: “When the soldier stood up in his stirrups (马镫), the heel helped him keep balance so that he could shoot more effectively.

    Before becoming a main part of modern women's clothing, high heels were used by Louis XIV of France. These shoes were status (身份) symbols Lets face it-nothing shows off status like uncomfortable, expensive and impractical clothing. They say the wearer doesn't have to work in fields or walk very far.

    Tonya, Elsa and Mark are students at LaGuardia High School in New York City. It's a school with regular academic (学术的) classes, but it also gives special attention to the performing arts. Tonya likes dancing, Elsa wants to be an artist and Mark is a singer.

    The students are all 15, and they're in 10th grade. They study subjects like English, math, social studies, science and PE. They also choose a foreign language: French, Italian, Spanish or Japanese. Students have many academic classes, but during the school day they also take classes in the arts, like theater, art, dance and music. Mark says, “I get the basic classes, but I also take a voice class and a music history class.”

    There is even more for LaGuardia students after school. There are more than 40 clubs for students. For example, there's a movie club, a music club and an environment club. “We have so many choices here,” says Tonya. “My favorite club is the camera club. I like taking photos. It's also a great way to meet people with common interests.”

    Students at LaGuardia can also do many sports. For example, they can play basketball, tennis, volleyball and soccer. Elsa is on the gymnastics team. She says, “I like being on a team. It makes me work hard and do my best.” Students practice after school. They compete against other high schools. Mark says, “At school, I study by myself. I'm a singer, and I do that alone, too. That's why I like playing on the basketball team. We work together and compete against other teams.”

    LaGuardia offers many great classes, clubs and sports for students. Students at LaGuardia get a good education and they also develop their own interests. Many LaGuardia students become dancers, singers and actors!

    Body language is a broad term for several forms of communication using body movements or gestures, instead of, or as a complement to, sounds, verbal language, or other forms of communication. In turn, it is one category of paralanguage, which describes all forms of human communication that are not language.

    Paralanguage including body language has been extensively studied in social psychology. In everyday speech and popular psychology, the term is most often applied to body language that is thought to be involuntary, but in fact the distinction between voluntary and involuntary body language is often blurred: a smile or a wave may be given either voluntarily or involuntarily, for example.

    Voluntary Body Language is less commonly discussed because it seems unproblematic. It refers to movement, gestures and poses intentionally made by the person: smiling, hands, imitating actions, and generally making movements with full or partial intention of making them and a realization of what they communicate.

    The relation of body language to animal communication has often been discussed. Human paralanguage may represent a continuation of forms of communication that our non-linguistic ancestors already used, or it may be that it has been changed by co-existing language. Some species of animals are especially skilled at detecting human body language, both voluntary and involuntary: this was the reason for trying to teach the chimpanzee Washoe American Sign Language rather than speech and perhaps the reason why the Washoe project was more successful than some previous efforts to teach apes how to dance.

    Body language is a product of both genetic and environmental influences. Blind children will smile and laugh even though they have never seen a smile. The ethnologist (文化人类学者) Iraneus Eibl-Eibesfeldt claimed that a number of basic elements of body language were universal across cultures and must therefore be fixed action patterns under instinctive (本能的) control. Some forms of human body language show continuities with communicative gestures of other apes, though often with changes in meaning. More refined gestures, which vary between cultures (for example the gestures to indicate "yes" and "no"), must obviously be learned or modified through learning, usually by unconscious observation of the environment.
