    The Internet company Google is testing its newest high-tech device, Google Glass. The company describes the glasses as wearable computers that would change the way people view others and the world.
    The glasses can make and receive calls, send and receive texts, take pictures, record video or search the web. You control Google Glass using your voice, and a touchpad on the right arm of the frame.
    Professor Marcia Dawkins is among a select group of people who have been given a chance to test out Google Glass."I thought this is something I definitely need for my classroom and hopefully for my personal life too."
    The Professor's Google Glass looks like a bright orange glasses, without the actual glass. But there's a tiny rectangular glass at the top right-hand corner. Through that glass, she has been recording video while biking. She also has been able to talk to her sister in Thailand, and she plans to use the device to teach a public speaking class.
    But not everyone is excited about Google Glass. Some are concerned about possible risks to privacy. John Simpson is the director of the privacy project at Consumer Watchdog."It is essentially going to allow people to come in and spy on you and record that, without you knowing what is going on."
    Google says that it has already addressed that concern. Mr Dale explained that in order to start the camera or record a video, the owner must say something out loud. "I activate the device, and say 'Okay, glass, take a picture.' Similarly, I have to push a little button on the top here so everybody around me will know a picture is being taken and a video is being recorded."
    But Filmmaker Chris Barrett showed just how easy it is to record people without them knowing it. His glass captured a man getting arrested after a fight. He shared the video on YouTube.
    Also some are concerned about the use of facial recognition technology on Google Glass. But Google says it will not approve the use of such applications. The Internet company says it is still testing its new device, and it hopes to make Google Glass available to the public by early next year.

    • 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
    此外还有下面表示法:
    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
