Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University's School of Life and Health Sciences. The findings suggest there may be some scientific basis of the "5-second rule" — the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the ‘5-second rule', until now it was unclear whether it actually helped.

    The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor floor types as carpet, cement floor to toast, pasta, biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: time is a significant factor in the transfer of bacteria from a floor surface to a piece of food, and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5 seconds. Professor Hilton said, "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time."

    The Aston team also carried out a survey of the number of people who employ the ‘five-second rule'. The survey showed that: 87% of the people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those that would, or have eaten food dropped on the floor are women. 81% of the women who would eat food from the floor would follow the ‘5-second rule'. Professor Hilton added, "Our study showed that a surprisingly large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the ‘5-second rule, which our research has shown to be much than an old wives' tale."

    The Bowler family had a very unusual experience this year. It was one of more than 400 families who applied to 1900 house, a reality TV show which took a typical family back a hundred years to see how people lived in the days before the internet, computer games and even electricity.

    The Bowler family spent three months in a London home without a telephone, computers, TV, or fast food. The bowlers wore clothes from 1900, ate only food available in England at that time, and cooked their meals on a single stove. Paul Bowler still went to work every day in a then uniform. The children changed their clothes on the way to and from school and their classmates didn't know about their unusual home life. Joyce stayed at home, cooking and cleaning like a typical housewife of the time, though everything took three times as long.

    So does Joyce think that people's lives were better in the old days?

    “I think people in the old days had just as many troubles and worries,” Joyce said. “And I don't think their life was better or worse, there were lots of things back then that I'm happy I don't have to deal with nowadays, but on the other hand life was simpler.” “We had a lot more time with our family, and it was hard being nice to each other all the time,” eleven-year-old Hilary said.

    So what did the Bowler family miss most about modern life while living in the 1900 house?

Paul, 39: “telephone and a hot shower”

Joyce, 44: “a quick cup of tea from a kettle you could just turn on”

Hilary, 11: “rock CD”

Joseph, 9: “hamburger and computer games”

    A speech is a wonderful opportunity to inform,persuade or entertain.The best speeches often take on a combination of all three of these components（组成部分）.However,before you can go about the writing of a great speech,it is important to set goals.Goals keep you,your speech and your audience focused.

What a goal is

    In the context of a speech,a goal is the purpose of the speech,and what it hopes to accomplish.For example,the goal of a eulogy（颂歌）might be to celebrate the life of a loved one.The goal of a speech at a political gathering would be to inform the crowd about the political position of a candidate and persuade them to vote and campaign for the candidate in question.

    Why a goal is important

    Without a goal,a speech is without direction.The goal informs the structure and content of the speech.For example,if a speech's goal is to convince people that smoking is bad for them,the speech will be structured with persuasive arguments to back up the goal.A speech with a goal of informing audience will keep the information fair and factual.

    A goal is incredibly important to the speech's ability to connect with an audience.If the speaker is unaware of the goal of the speech,the audience will likely be unaware as well.This severely reduces the effectiveness of the message.

    Besides informing the audience of the content and structure,a speech's goal drives the speaker to greater heights. If a speaker is asked to speak on a specific subject but never establishes the goal,they won't know where to start in the research,organizing and writing of the speech.

    If you have been charged with delivering a speech,establishing a goal can seem difficult at first.There are several things to take into consideration.First,think about who you will be speaking to.The demographic（人口统计）of your audience will likely determine whether you will be able to persuade them or whether they will be able to sit through（一直坐到……结束）.Second,think about the topic itself.If the topic is something controversial（有争议的）,it may worth your while to consider an informative approach to present both sides of the issue.Finally,consider your resources.A speech with an informative or persuasive goal usually requires a great deal of research,and sometimes takes more time to write.

    We often just use our sense of sight, touch, smell, and taste to eat food. But what about our sense of hearing? Does sound also affect our dining experience?

    A new report answers, “yes, it does.”

    That answer comes from researchers at Brigham Young University and Colorado State University in the United States. They found that hearing is important in the eating experience.

    Hearing is often called “the forgotten food sense”, says Ryan Elder. Elder is an assistant professor of marketing at Brigham Young University's Marriott School of Management. He says that if people notice the sound the food makes as they eat it, they might eat less. On the other hand, watching loud television or listening to loud music while eating can hide such noises. And this could lead to overeating.

    For the study, the researchers wanted to test whether the sounds of eating—chewing, chomping and crunching—had any effect on how much a person ate. During the experiments, the test subjects wore headphones and listened to noise at either a high or low audio level. Then researchers gave them a crunchy snack: pretzels. The study found that subjects who listened to the higher volume noise ate more pretzels than those with the low audio levels.

    Elder says that when hiding I heard sounds of eating, like when you watch television or listen to loud music while eating, we take away the sense of hearing. And this may cause you to eat more than you would normally. The researchers are calling this, the “crunch effect”.

    The researchers admit that the effects may not seem like much at one meal. But over a week, a month or a year, all that food can really add up.

    Generally speaking, government regulations normally ban anything from smoking in public places to parking in certain zones. But officials in the Brazilian town of Biritiba Mirim, 70km (45miles) east of Sao Paulo, have gone far beyond that. They plan to prohibit residents from dying early because the local cemetery(墓地) has reached full capacity.

    There's no more room to bury the dead, they can't be cremated(火化) and laws forbid a new cemetery. So the mayor has proposed a strange solution: outlaw death. Mayor Roberto Pereira says the bill is meant as a protest against federal regulations that prohibit new or expanded cemeteries in preservation areas. "They have not taken local demands into consideration", he claims.

    A 2003 decree(法令) by Brazil's National Environment Council forbids burial grounds in protected areas. Mr. Pereira wants to build a new cemetery, but the project has been stopped because 98% of Biritiba Mirim is considered as a preservation area.

    Biritiba Mirim, a town of 28,000 inhabitants, not only wants to prohibit residents from passing away. The bill also calls on people to take care of their health in order to avoid death. "I haven't got a job, nor am I healthy. And now they say I can't die. That's ridiculous," Amarido do Prado, an unemployed resident said.

    The city council is expected to vote on the regulation next week. "Of course the bill is laughable, illegal, and will never be approved," said Gilson Soares de Campos, an assistant of the mayor. "But can you think of a better resolution to persuade the government to change the environmental decree that is prohibiting us from building a new cemetery?" The bill states that "offenders will be held responsible for their acts." However, it does not say what the punishment will be.

    I remember little of the journey which started so early in the morning. I only know that the day seemed extremely long, and that we appeared to travel over hundreds of miles. Calmed by the sound of the coach wheels, I fell asleep. But I had not slept long when the coach stopped, the door was opened, and I saw a servant standing there.

    "Is there a little girl called Jane Eyre here?" she asked. I answered "Yes," and was then lifted out. My trunk handed down, the coach instantly drove away. I looked about me. I could see a house with many windows. There were lights burning in some of them. We went up a wide pebbly path, splashing wet, and were admitted at a door. Then the servant led me through a passage into a room where she left me. I stood and warmed my frozen fingers at the fire and looked around. There was no candle, but the light from the fire showed papered walls, a carpet, curtains and gleaming furniture. Then the door opened, and a tall lady with dark hair, dark eyes entered followed by another who looked younger. "The child is very young to be sent alone," said she, putting her candle down on the table. She looked at me for a minute or two and then added, "She had better go to bed soon; she looks tired."

    Led by the younger lady, Miss Miller, through passage after passage, we came, at last, to a long, wide room filled with the hum of many voices. There were many tables, and seated all round on benches were a large number of girls aged from nine to twenty. Seen in the dim light of the candles, their number appeared above eighty. Each was dressed in a brown old-fashioned dress of cheap material. It was their hour of study.

    Miss Miller signed to me to sit on a bench near the door, then walking up to the top of the long room she cried out "Monitors, collect the lesson-books and put them away!"

    Four tall girls arose and went round, gathered the books and removed them. Miss Miller again ordered, "Monitors, fetch the supper-trays!" The tall girls went out and returned presently, each bearing a tray. Some food and water was in the middle of each tray. The food was handed round and everyone drank from the same mug. When it came to my turn, I drank too, for I was thirsty, but I did not touch the food. From there I was taken to my hard bed where I thankfully fell asleep immediately.
