It is often said that the language we use online is less formal than that we use in a letter, or in direct speech sometimes. This is true, but it can also make us in trouble sometimes.
The thing about online communication is that you have no idea what the person who is reading your messages is feeling. For this reason, it is always a good idea to be polite and cautious when writing e-mails or messages to your friends.
Chinese can be a direct language, but in English, people often talk about a subject in another way. So instead of saying “Please meet me here” or “Do this for me now”, English speakers usually go for indirect phrases like “Would it be possible”, “if you have time” or “It would mean a lot to me if…”
If you have a close friend, you may still run into trouble because of your jokes. If you have asked someone to do something and they need a bit more time, you might joke with him: “What? You still haven’t done it yet? What’s wrong with you?” While this seems funny to you, your friend may feel unhappy.
If you have foreign friends in different countries, the time difference can also be a factor. While you are waking up for class on Friday morning, they may be having a party on Friday night. You will be serious and they will, probably, be excited. So don’t be angry if they seem not to care about you. Just try to message them at the proper time.

　　SARS is a dangerous new illness. Doctors are trying to find out what causes it. They are working hard to find a treatment(治疗方法) for it.

　　The letters SARS stand for severe acute respiratory syndrome(严重急性呼吸综合征). The first cases of SARS were in Guangdong and Hong Kong in China. Travelers spread(传播) SARS to many other cities. By June 6 there were more than 5320 cases of SARS in our country and nearly 340 died from it.

　　SARS seems to be spread when a sick person coughs or sneezes, even breathes. People who stay in the same place with SARS patients or who come close to them, may catch it. It may be spread by touching things that a SARS patient has touched. Doctors isolate(隔离治疗) people ill with SARS, and they have to quarantine(隔离) those who are close to SARS patients. Those who travel to or from a SARS city and seem to have any cases of SARS should be quarantined. They should not go to work, school or any other public place. Quarantine helps prevent SARS from spreading.

　　SARS usually begins with a fever, a headache, and body aches. People ill with SARS have a dry cough and trouble breathing.

　　To protect ourselves away from SARS, we should do more exercise, wash our hands often, and open windows to let fresh air in.

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes (态度) surprisingly shows that their family life is happier than it has ever been in the past. “We were surprised by just how positive (积极的) today’s young people seem to be about their families,” said one member of the research team. “They’re expected to be rebellious（叛逆的）and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”
So it seems that these parents are much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel LaSalle. “I always tell them when I’m going out clubbing. When they know what I’m doing, they’re fine with it.” Susan Cromer, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call talk or discussion. For example, when I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion（叛逆）is not based on real facts. A researcher explains, “Teenagers were thought to be different from others in a part of time in our social history. But to our surprise, they say they are getting on well with their parents. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled.”
