    In order to present the best presentation and eliminate room for error, you need to keep in mind certain guidelines. Here are some of my ideas for presenting quality presentation that demand genuine attention from your listeners.

    82.

     
      
    Picking out a topic is the hard part, when it comes to choosing from a list of presentation subjects. It has to be interesting, impactful and unique; therefore it is crucial to choose something you care about rather than randomly selecting one. Ask yourself if it covers angles-is it informative? Will it keep my listeners hooked? Will it create an air of boredom? Will I be able to get all my facts and research done? Is it appealing to me, but not to them?

    83.

     
      
    There's nothing more annoying than having someone blabber on about a topic he/she hasn't done extensive research on. It is obvious from the way they speak, how monotonous their tones sound and how robotic their movement and gestures are. So don't be that someone. Take the effort to learn as much as you can. Make it matter to you, and remember how it can impact your listeners, and enlighten them on things they didn't know about at all.

    84.

     
      
    No one is perfect, and there are bound to be mistakes or circumstances that you didn’t count on and couldn’t avoid. You could stutter with a word, mix up slides, or forget some important sheets of your presentation and so on. Straighten up. Crack a minor joke in your defense. In other words improvise and don't beat yourself up about it or else your presentation will end in disaster. Don't let it ruin the rest of it, and finish the presentation as planned, so that people think more of how well it ended.

    85.

     
      
    The best thing about presenting a topic is eye contact. If you are able to say it by heart, and not by looking at a piece of paper, you will have mastered the most effective presentation technique. Memorize your lines, and points, and only glance at your notes occasionally if you think you may forget something. In the end, if you think that you are well prepared to answer questions, then by all means invite them.

  • 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。
        Read the book from the first.(宾语)从开头读这本书。
        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。
例:You may have a third try. 你可以第三次尝试。


序数词知识体系:

 


约数的表达方法

用tens/dozens/scores/hundreds/thousands/millions of 表示“几十、几百、上千、成千上万”等。
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
        hree hundred people  三百个人

分数词的构成和用法:

1)分数词构成法:
分数词(FractionalNumerals)由基数词和序数词构成,基数词代表分子,序数词代表分母。除了分子为1的情况下,序数词都要用复数形式:
如:1/4:one-fourth
        5/9:five-ninths
        2/3:two-thirds
       17/5:three and two-fifths
       7/12:seven-twelfths
       379/8:forty-seven and three-eighths

如:1/2:a(one) half
        1/4:a(one) quarter
        3/4:three-quarters
        9/4:two and a quarter
        3/2:one and half
        31/4:seven and three quarters
