Stop. Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.
Noise can be caused by many kinds of machines, such as motorcycles, jet planes, farm tractors(拖拉机), rock music is also noise.
What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant(不断的) loud noise can cause a loss of hearing.
Scientists use a unit of measure called decibel(分贝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level(层次) causes the great hearing loss.

We all have our own ways of sharing our life experiences with others.

Spencer Johnson’s story Who Moved My Cheese? Shows changes exist in (存在于) our life. Life changes and so we do. We must change ourselves to face the changing environment, or we will fail.
Just look at the cycle (循环) of the seasons. Trees bud (发芽) in spring and in summer their leaves turn green. In autumn, their leaves start to fall onto the ground. When winter arrives, there are no leaves on trees. Next spring the cycle begins again. Since we know there are cycles in nature, we can prepare for them.

Since we accept the cycles of nature, we should also accept the changes in our life.

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 into a few letters called acronyms. 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(缩写). They are shortened forms of words. Some common abbreviations are:
Info(information) puter (computer)
Pie(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 keywords to draw “feeling”, such as:
:-)(happy) :-p(joking) :-( (sad) :-0 (surprised)
These days, many forums(论坛) have picture feelings. For example,
(sad) (happy)
There are even whole new words, like“newbie’s”(someone who is new on a chat board or forum).
It takes time for people to get used to e-talk. Also, different groups on the Net have their own special ways of communicating. Newbie’s have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.

小题4:E-talk will probably _______.| A．keep changing | | B．be easy by people on the telephone | | C．be used by people on the telephone | | D．make life easier |
小题5:What’s the best title for this passage?| A．E-talk Language | B．Picture Feelings | | C．How to Use Abbreviations | D．use the Internet |
