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.

Dear Mike，

      I'm so glad you're coming to China! Your mother，our foreign English teacher，told me you're worried about what you should and shouldn't do as a guest in China．Here's some advice．You will probably be invited to a big meal. You may find it earlier than you expect because Chinese people eat dinner much earlier than people in the West．There will be a lot of different dishes，not just three courses．You may find it difficult to use chopsticks if you haven't tried before．It's a good idea to get some practice．When the food is served，you should take time to look at it. The preparation takes a long time and everything will look beautiful．The plates will be placed in the middle of the table，for everyone to share．Take a little of everything and then have some more of the things you like．Chinese people like to talk about food，so it's a good topic of conversation．At the end of the meal，you will usually be served with fruit．Eat your fruit，thank your friends， and go．

      I hope this is helpful．E-mail me if you have any other questions． 

                                                                                                                              Yours，

                                                                                                                                   David Zhang

    Audrey is a Chinese-American student. She has found value (价值) differences between Chinese and Americans.

    About money:

    ①Americans would like to spend more than they have, so many of them are always in debt (欠债). Chinese usually spend less than they have, so many of them always have money left in the bank.

    ②American kids love to make money by themselves. Chinese kids always ask their parents for money.

    ③Americans parents think that it is not useful to send their children to an expensive university. Chinese parents would do anything to send their children to good universities and that might make them very poor sometimes.

    About school:

    ①Many American girls take part in sports, dancing and singing groups while Chinese girls take part in academic groups.

    ②Some American students think that "B" is a gift while Chinese students think that "B" is terrible.

    About American parents and Chinese parents

    American parents allow their daughters or sons to have some part-time jobs in their free or at weekends. Chinese parents usually don't allow their children to do so in middle or high schools.
