    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.   1  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.  2 
    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.   3  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.
      4  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 strong about it, think twice before saying anything. Having good manners yourself doesn’t give you license to correct everyone else.   5  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 status. Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.
    A.It’s natural that there are some people who speak rudely or make mistakes online.
    B.Repeat the process till you feel sure that you’d feel comfortable saying the words to the person’s face.
    C.Everyone was new to the network once.
    D.The basic rule is simple: treat others in the same way you would want to be treated.
    E. When you send short messages to a person online, you must say something beautiful to hear.
    F. You should either ignore the person, or use your chat software to block their messages.
    G. If you do decide to tell someone about a mistake, point it out politely.

  • 序数词

序数词的概念:

表示顺序的数称为序数词。如:first, second, third, fourth。


序数词的构成与用法

1、序数词的构成:
①一般来说,是由相应的基数词加词尾th构成。
   例:four+th→fourth
           six+th→sixth
           seven+th→seventh
           ten+th→tenth
②下面这些基数词在变为序数词时,有特殊的变化。
例:one→first
        two→second
        three→third
        five→fifth
        eight→eighth
        nine→ninth
        twelve→twelfth
③十位整数序数词的构成方法是将基数词的词y变成i,然后再加eth。
例:twenty→twentieth
        thirty→thirtieth
        forty→fortieth
        ninety→ninetieth
④两位或两位以上的基数词变成序数词时,仅将个位数变成序数词。
例:twenty-one→twenty-first
        thirty-five→thirty-fifth
        a hundred and fifty-three→a hundred and fifty-third

2、序数词的用法:
①序数词在使用时,一般加上定冠词。
例:the first book
        the second floor
        the third day
        the fourth week.
②序数词在多数情况下都用作定语,有的也可以作表语、主语和宾语。
例:The may1st is Labour Day. 五月一日是劳动节。
        My room is on the second floor. 我的房间在二楼。
        The first is larger than the secon.(主语)第一个比第二个大。

        You'll be the sixth to write.(表语)你将是第六个写的。
③序数词的前面可以加上不定冠词,用来表示“再一”,“又一”的意思。

如:The boy bought dozens of pencils.            
        Thousands of people died in the earthquake.
注意: (A):dozen, score, hundred, thousand, million等表示确切数量时,不用复数。
如:five dozen (of) eggs   五打鸡蛋
