  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(縮寫). 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(論壇) 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.

We live on the earth. We use the sea around us. What do we take from the ocean? And what do we give to it?

We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people.  1.   We take minerals(礦物) from the ocean. We can get salt by evaporating(蒸發(fā)) seawater.  2.    Many other minerals, such as gold, can be also got from the sea, but not by simple evaporation. 3.    Seaweed(海草) becomes food of many kinds— even candy, and ice cream—as well as medicine. Believe it or not, fresh water is another gift from the sea. We can’t drink ocean water.   4.   But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.

The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea? We pollute the ocean all the time. 　 5.　 Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.

We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.

Have you ever heard an echo of your voice?
An echo is a reflected(反射)sound. Stand in a very large, empty hall with nothing on the walls. Then shout. The sounds you make will hit the walls and come back to you. The walls reflect the sounds. These reflected sounds are called “echoes”.
We can use reflected sound to make sound travel farther. Hold a watch about fifty centimeters from your ear. You cannot hear it. The sound of the watch travels a short way in all directions. It does not travel as far as your ear. You can make it travel to your ear by using a roll of cardboard(紙板筒).
Make the roll of cardboard about fifty centimeters long. Put one end over your ear and hold the watch at the other. Now you can hear the watch because the sound has not gone in all directions. It is reflected down the roll to your ear.
A megaphone(喇叭筒)works in the same way. It makes sound travel farther. It reflects the sound into a beam which can travel a long way. In the ship, the sailor uses the megaphone to make his voice travel. Without the megaphone, his voice cannot travel far.
We use reflected sound in many ways. We use it to measure the depth of the sea, for example. Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them.
