The Internet has opened up a whole new online world for us to meet, chat and go where we've never been before.

    But just as in face to face communication, there are some rules of behavior that should be followed when on line. {#blank#}1{#/blank#}  Imagine how you'd feel if you were in the other person's shoes. For anything you're about to send: ask yourself, “Would I say this to the person's face?” If the answer is no, rewrite and reread. {#blank#}2{#/blank#}

    If someone in the chat room is rude to you, your instinct(本能) is to fire back in the same manner. But try not to do so. {#blank#}3{#/blank#} If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

    {#blank#}4{#/blank#} Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else. {#blank#}5{#/blank#} At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended（冒犯）. It is not polite to ask others personal questions such as their age, sex and marital(婚姻的) status. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions.

    What should you think about in trying to find your career（职业）? You are probably better at some school subjects than others. {#blank#}1{#/blank#} A boy who is good at mathematics can use that in an engineering career. {#blank#}2{#/blank#} So it is important to do well at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. {#blank#}3{#/blank#} Knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.

    {#blank#}4{#/blank#} If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.

    Facing your weak points is also part of knowing yourself. {#blank#}5{#/blank#} Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

A. It is better to face any weaknesses than to pretend they do not exist.

B. A girl who spells well and likes English may be good at office work.

C. He may do well in his future work.

D. Although not all subjects can be used directly in a job, they may have indirect value.

E. Your school must have taught you the skills.

F. These may show strengths (优势) that you can use in your work.

G. If you have had a part-time job on Saturday or in the summer, think what you gained from it.
