    Can you escape from a sinking vehicle? The answer is obviously yes. “But you’ve got to be quick.” said Gordon Greisbeck, a professor from the University of Manitoba’s. Here he gives four rules of survival.
    Rule 1.  Don’t call 911 until you are out of the car. You should get out of that vehicle immediately after unbuckling. Think about calling 911 once you’ve made it out alive. ‘Time is very important,” Greisbeck says, “If you touch your cell phone, you’re probably going to die.”
    Rule 2.  Don’t open the door. Roll down or break the windows instead. Opening the door is very difficult against the water pressure and it also allows so much water into the vehicle that it will speed up the sinking process. Since most vehicles now have electronically controlled windows, it is probable that the circuits (电路) will short before you have a chance to roll them down. So you’ll need a tool like the Life Hammer to break the windows open. And make sure these tools are within reach at all times.
    Rule 3.  Children first. Everybody should get out of their own window if possible, but the kids are going to have a harder time fighting through the rush of water, so push them out if you have to. Greisbeck suggests starting with the oldest kids and taking the youngest out in your arms.
    Rule 4.  Get out. Swim through the broken windows as fast as possible. You can’t imagine what will happen in the next second. Any intention to take your belongings can be deadly.
    If you’ve failed to get the windows rolled down or broken, you’ll still have the slightest of chances to escape. Once water fills the car, the pressure will be equalized and you will be able to open the door. But to do this, you will also have to be expert at holding your breath in an extremely stressful situation.

    序数词

    等考点的理解。关于这些考点您可以点击下面的选项卡查看详细档案。
    • 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
