After a confirmed rabies(狂犬病) case in Parke County, Indiana, experts are urging caution if you find a bat(蝙蝠) in your home or office.

    “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.”

    The Speaker was the title of an eight-part television series. It was produced by the BBC in the UK. The aim of the series was to find Britain's best young speaker.

    Young people between the ages of 14 and 18 from across the country were invited to take part in The Speaker. Applicants included tough-talking teens, jokers, and shy, sensitive types. The one thing they had in common was a desire(渴望) to talk publicly and enthusiastically about what was important to them.

    Each applicant was asked to prepare and film a one-minute speech on any subject-from pop music to politics, from hooligans(小流氓) to homework. From all the entries received, 160 speakers were chosen by three judges. These speakers were invited to the next stage of regional auditions(海选), where they had to deliver their one-minute speech again, but this time in front of the judging panel(评审团) and an audience. Of the 160 speakers, only 20 were selected by the judges to go through to the next stage. They then had to give another speech on a subject they were given only seconds before making the speech. Some competitors also had to speak about a picture, again without any preparation.

    The final eight were then coached by celebrity mentors(指导老师) and given new challenges to help improve their speaking skills. Their speeches were judged by the judges and their mentor. By the last part in the series, which was shown at the end of April 2009, only three competitors remained. They were taken on a research trip to Malawi, where they found out first hand the effects of children's rights, ahead of their final speech. Duncan Harrison, a 14-year-old schoolboy from Bristol was chosen as the winner by the judges and mentors.

    When asked what makes a good speaker, the actor, director and teacher, Jeremy Stockwell, who was one of the judges on the series, said, “An effective speaker must know and trust who they are, what they have to say, and why they have to say u. Whether you're playing Hamlet, delivering a political message or presenting a school meeting, you must have a story to tell, a message to pass on and a clear sense of purpose.”

    The pupils of Grangetown High have been busy getting to know their newest and tallest classmate — a 7-meter-tall giraffe outside their school.

    The giraffe is a huge sculpture (雕像). The school's headmaster noticed it in an artist's garden as he drove past one day, and thought it would be perfect for his school. “I knew everyone would love it,” he said, “because our basketball team is known as the Grangetown Giraffes, and they wear giraffes on their shirts. So I asked them to write to the artist, asking how much it would cost to buy the giraffe. He was very kind and got it ready to deliver (递送) in six weeks — all for nothing! It was expected to arrive one Sunday morning, so that the pupils would see it when they got to school on Monday — at that time they had no idea that we were getting it.”

    The artist, Tom Bennett 9 was a university professor of chemistry before he retired in 2012 and only took up metalwork a couple of years ago. “I've always drawn pictures,” he said. 441 can even remember doing it on my first day at school — I drew a horse. I wanted it to be the best horse picture ever, but I don't think I succeeded.” Tom's first metalwork was a bicycle on which he and his wife could go cycling together, “It was the most uncomfortable bike ever created,” he said, “so I gave up making bicycles and went into sculpture instead.”

    Meanwhile the pupils at Grangetown High are very happy with their new classmate. “We're going to hold a competition to give it a proper name,” said one girl. “Everyone likes the expression on its face, so perhaps that will give us some ideas.”

    Can you remember the first time you learned to ride a bike or drive a car? Learning these skills changed your life forever and opened up new horizons. Learning about computers can be like learning how to ride a bike or drive a car. Once you have invested the time to master the skills , you will never go back to the old days. The new technology is simply too convenient and too powerful.

    Technological developments through the years have enabled us to do more with less effort. We have continuously looked for better ways of doing things. Each invention and new development has allowed us to extend our capabilities. Today we see one of the most dramatic technologies ever developed—the computer. It extends the capabilities of our minds.

    Computers have saved organizations millions of dollars. Furthermore, these same computer systems have opened up new opportunities that would have gone undiscovered or neglected. The computer may multiply what we can do, and the return on investment is high. The growth of computer usage is surprising. On the other hand, the computer can do serious damage. Invasion of privacy(侵犯隐私), fraud(欺诈), and computer-related mistakes are just a few shocking examples.

    The computer is like a double-edged sword. It has the ability to cut us free from some activities, but it can also cut deep into profits, personal privacy, and our society in general. How it is used is not a function of technology. It is strictly a function of how people decide to use or misuse this new technology. The choice is yours, and only through a knowledge of computer systems will you be able to avoid the dangers while enjoying the many, many benefits of the computer age.

    Every object tells a story. Even the most ordinary objects can present to us powerful images. Sometimes it is the ordinary nature of these objects that actually makes them so extraordinary. Such is the case with an old leather shoe in a museum in Alaska. At first glance it does not look like much. It is a woman's shoe of a style popular in the 1890s. But what is unique (独特的) about this shoe is where it was found. It was discovered on the Checkout Pass, the famous trail used by the people seeking gold in Alaska. Who it belonged to or why it was left there is not known. Was it perhaps dropped by accident as the woman climbed up the 1500 stairs carved outface? Or did she throw away goods that she didn't need in order to travel lighter?

    Over 100, 000 people with “gold fever” made this trip hoping to become millionaires. Few of them understood that on their way they would have to cross a harsh wildness. Unprepared for such a dangerous journey, many died of starvation and exposure to the cold weather.

    The Canadian government finally started requiring the gold seekers to bring one ton of supplies with them. This was thought to be enough for a person to survive for one year. They would carry their supplies in backpacks (背包) each weighing up to fifty pounds; it usually took at least 40 trips to get everything to the top and over the pass. Whoever dropped the shoe must have been a brave and determined woman. Perhaps she was successful and made it to Alaska. Perhaps she had to turn back in defeat. No one will ever know for sure, but what we do know is that she took part in one of the greatest adventures in the 19th century.

    The theatre in Shakespeare's time was much different than it is today. Authors wrote plays for the masses, especially those who couldn't read or write.

    The theatre changed a lot during Shakespeare's lifetime. The authorities didn't like it and didn't allow acting in the city itself: They thought it had a bad influence on people and kept them from going to church. Queen Elizabeth, on the other hand, loved acting and helped the theatre become popular.

    The theatre in Shakespeare's time was full of life. People did not sit all the time and it was not quiet during the performance. The audience could walk around, eat and drink during the play.

    Theaters were open arenas or playhouses that had room for up to three thousand people. There was almost no scenery because the dialogue was the most important part of the play. Colourful and well-designed costumes were very important and told the people about the status of a character. Women never performed in plays, 80 young boys played female characters. The performances took place in the afternoon because it was too dark at night.

    There was no stage crew as there is today. Actors had to do everything themselves-from making costumes to setting the stage. Plays were organized by acting companies. They performed about 6 different plays each week because they needed money to survive. They had almost no time to rehearse (排练).

    The companies in Shakespeare's time had a rank system. The company belonged to shareholders and managers. They were responsible for everything and got most of the money when the company was successful. Sometimes they even owned their own buildings. Actors worked for the managers and after some time became a permanent member of the company. Apprentices (学徒) were young boys and were allowed to act in unimportant role. They also played female characters in plays.
