    We’ve all done it at one point or another. You’re driving along to work or school when that familiar sound reaches your eardrums(耳膜). You look down, reach into your pocket and begin to read, your steering wheel(方向盘) in one hand, your phone in the other. As you respond to that text message from your friend, you look intermittently(间歇地) at the road, and then back down at your phone. You’ve done it plenty of times before. What can go wrong?
    What do you think is the number one killer of teenagers in the U.S.? Drugs? Alcohol? Violence? The answer is distracted driving. According to the National Safety Council, over 24 percent of all motor vehicle crashes involve cell phone use. Either a quick 30-second phone call or a simple text reading may be the cause of a traffic accident. In addition, drivers who talk on a cell phone, whether hands-free or not, are four times more likely to crash.
    The risk of teenagers getting into an accident rises sharply. According to keepthedrive.com, more than 3,000 teenagers die in car accidents each year with about another 450,000 teenagers being injured. Additionally, according to a University of Utah study, reading or sending even one text message is equal to having a 0.08 alcohol level. In most states, that is considered as drunk-driving.
    So, how do you prevent yourself from the danger of distracted driving? The answer is simpler than you might think. Put your phone away. Mute(消音) your phone or just turn it off while driving. If you still can’t help reaching for your phone, throw it on the backseat. This way, you won’t be able to get to it until you arrive at your destination.
    You may get away with talking on the phone now, but there may be a day when you don’t. Dropping your phone may be an inconvenience, but it’s better than being a victim of your distracted driving.

  • 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。

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
