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.”

    It's the time of year when graduates are looking forward to putting constant exams behind and moving on to a more exciting stage of their lives. But in the digital age, not everything is so easily left behind, because they have created a digital footprint that's often not easy to cover up. However, there are various actions they can take to make that online presence（网络形象） more appreciating.{#blank#}1{#/blank#}

    Clean up your Facebook account

    Clean up your Facebook page and get rid of anything that could be considered offensive （冒犯的，无礼的） or held against you. Remember, the test is no longer “Would you want grandma to see it?” but “{#blank#}2{#/blank#}”

    Use a professional looking photo{#blank#}3{#/blank#}, so make sure that first impression is a good one. Again, what worked at school is unlikely to impress the employers. Also, be consistent （一致的）and use the same photo on all your online platforms.{#blank#}4{#/blank#}

    While it's important to make the transition（过渡）from school to the workplace, you don't want to leave everything behind. Make a point of keeping in touch with your school friends, teachers, professors, sports coaches, or anyone who could be helpful to you as you establish a career.

    Be yourself

    Nobody can be more like you than you.{#blank#}5{#/blank#} Turn your social networking pages into your own personal website, and start marketing your own individual ,brand!

A．Grow your network

B．Search your memory

C．A picture is worth a thousand words

D．Whom would you want to see it?

    City people usually think they are a lot smarter than country people. They often laugh at simple country ways. But people do not laugh at country music. It is one of the most popular kinds of music in the United States today.

    Perhaps it is so popular because it is about simple but strong human feelings and events—love, sadness, good times and bad times, it tells real life stories and sounds the way people really talk. As life becomes more and more complicated(复杂的), it is good to hear music about ordinary people.

    Country music, sometimes called country western, comes from two kinds of music. One is the traditional music of the people in the Appalachian Mountains in the eastern United States. The other is traditional cowboy music from the West. The singers usually play the guitars, and in the 1920s they started using electric guitars.

    At first city people said country music was low-class. It was popular mostly in the South. But during World War Ⅱ, thousands of Southerners went to the Northeast and Midwest to work in the factories. They took their music with them. Soldiers from the rest of the country went to army camps in the South. They learned to like country music. Slowly it became popular all over the country.

    Today country music is popular everywhere in the United States and Canada, in small towns and in New York City, among black and white, and among educated and uneducated people. About 1,200 radio stations broadcast country music twenty-four hours a day. People sing it in their languages. The music that started with cowboys and poor farmers is now popular all over the world.

    Nola is a 41-year-old northern white rhino (犀牛) that lives at the San Diego Zoo Safari Park in Escondido, California. She is one of only four remaining northern white rhinos in the world, and the only one in the western part of the earth. The other three live in Kenya (肯尼亚).

    Rhinos have lived on earth for more than 40 million years, but they are now at the risk of dying out. Hunters illegally hunt rhinos for their horns (角), which are used for art, jewelry, and decorations. They sell the horns for thousands of dollars per pound, though it is not allowed by law. Rhino horns are also prized as a key part in traditional medicine, even though scientific tests have proven that the horns cannot cure illnesses. Experts say that every eight hours, one rhino will be hunted.

    Scientists are trying to find ways to prevent rhinos from dying out. In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell samples (细胞样品) from more than 8, 000 different animal species until now, including the northern white rhino. Scientists hope that by studying the rhino cells, they will gain greater understanding of the species, and will find ways to increase its number.

    Jeanne Loring works with the Frozen Zoo. Loring's research focuses on pluripotent stem cells, which are cells that can renew and become any cell type. Coloring's lab at TSRI is working together with scientist Oliver Ryder of the San Diego Zoo to use plenipotentiary stem cells to try to increase the number of the northern white rhino. Loring said the goal is to start producing new rhinos through this method over the next couple of years.
