    Want to stay away from colds? Put on a happy face.
    Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from colds, according to a new study. It's possible that being happy helps the body fight illnesses, say the researchers from New York University.
    "It seems that positive feelings may reduce the danger of illness," said the study's chief researcher Sheldon Cohen.
    In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People who showed feelings were also less likely to tell their doctors that they felt ill.
    In this study, Cohen's interviewed 193 adults every day for two weeks. During the interviews, the people were given colds by doctors and had to stay alone in a room for six days.
    The results showed that everyone in the study was equally likely to get ill. But for people who said they felt happy during the research period, their illness are less serious and lasted for a shorter time.
    Cohen believes that when people experience positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried about your health, look on the bright side more often.

    A．People talked about their feelings every day.

    We use the Internet for many things: business, shopping, writing letters, talking to people, finding information, and so on. In recent years, a new kind of English has grown on the Internet. There’s no real word for it yet, so we’ll call it e-talk. People don’t like typing too much. To save time, they turn phrases (短语) into a few letters called acronyms(首字母缩略词). Acronyms are often used in chat rooms.
    Some of them are:
    BTW(by the way)     BRB (be right back)
    LOL (laughing out loud) IMO (in my opinion)
    People also use many abbreviations. They are shortened forms of words. Some common abbreviations are:
    info (information)    puter (computer)    pic (picture)      sec (second)
    We usually don’t see people when we communicate on the Net, so people have new ways to show feelings. Most people use their keyboards to draw “feeling”, such as:
    : ) (happy)     :-( (sad) ;    : P (joking)   : O (surprised)
    These days, many forums have picture feelings. For example:
    happy          sad         angry        cool
    There are even whole new words, like ‘newbie’ (someone who is new on a chat board or forum). When you write something bad about someone else, it’s called ‘flaming’ the person.
    It takes time to get used to e-talk. Also, different groups in the Net have their own special ways of communicating. Newbies sometimes have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.
    小题1: Why do people type acronyms?
    A．To show their feelings.
    B．To make jokes.
    C．Because people can type them quickly.
    D．In this way, newbies won’t understand them.
    小题2:What does “My puter is not working well. :-( ” mean?
    A．The person is happy about getting a new computer.
    B．The person has to go away from their computer.
    C．The person is angry at somebody.
    D．The person is sad that his computer is having problems.
    小题3:If someone is angry, what may he type?
    A．B．C．LOLD．BRB
    小题4:E-talk will probably_________.
    A．keep changing
    B．stay the same
    C．be used by people on the telephone
    D．be easy for newbies to understand
    小题5:People can do the following through the Internet except _________.
    A. doing shopping                B. writing diaries
    C. eating foods                   C. playing games

    There are about 80.000.000 mines under the ground in more than 60 countries. It is difficult and dangerous to clear these mines.About 50 people including many children were killed or hurt each day.In 2003，APOPO，a Duch research company that trains the animals,came up with the idea of using rats to search for the mines.
    The animal trainers found that a kind of rats from Africa were clever and had a sharp sense of smell.The rats were about 75 cm long and weighted about 1.35 kg.light enough to run across a minefield without setting off the mines.
    In January 2004，the  APOPO startec this preject.First ,the trainers let the 4-week-old baby rats get familier with humans. A few weeks later，the rats were no longer afraid of people and the things around them.Then they were trained to connect a click sound with food.After the rats had learned that ,the trainers then taught them to tell the different between the smell of mines and other smells.When the rats could do it，the click was sounded and they were given a bit of bananas.The method was called clicker training.“The training isn’t easy.”said the trainer Adulish Mebomvu.“You have to be patient.Sometimes I get angry,but then again.I tell myself these are animals.”
    After nine months’ training,the rats were taken to 4 minefield. They ran across the minefield ,stopped, sat and searched the ground to tell the deminers that they smelt out a mine. Then the mine was cleared.It had taken two deminers a day to clear a 200 m2 minefield. But with the help of two rats they could finish it in two hours.
    The rats and the deminers saved thousands of lives.“The rats did this job much better than we expected.So far they have helpde to make almost 2.000.000 m2 of land safe.They are heroes.”said Bart Woetjcds.the head of the APOPO.
