    Most American teenagers used to spend their summer vacations holding multiple jobs. However, with the increase in gas prices, teenagers chose to stay at home instead of going out of the town. “I wish the prices would        .The expense of driving to places is affecting our daily life.”said Alicia, still a senior at Enochs High School in Modesto, California.
    Alicia, who spent her summer at her dad’s house, said that there would be no point in getting a job. “The drive to my workplace is so long that I would hardly be making any profit because all my money would be going toward gas,”she said.
    Teenagers are now forced to give up the pleasure of driving around the town without purpose.“Instead of driving around looking for something to do, I now find myself planning the way in advance so I don’t waste necessary gas,” said Stephen Macko, a student at Davis High School in Modesto.
    What kinds of things are teenagers doing in order to conserve gas? Alicia saves gas by doing all of her things at one time so she doesn’t have to go home and leave again.
    “I try to do it all in one trip so I don’t have to always be running around and wasting gas,”she said.“I know that when I go to lunch with my friends, we make sure to go somewhere near all of our houses so we save gas.”“But it’s hard, considering I drive a big truck. I also try to get a lift from my friends when they are going to places that I am going to.”said Stephen. Some try not to accelerate too much. Teenagers will have to continue changing their lifestyles unless the price of gas decreases. However, that might not be a bad thing.

  • 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。

        You'll be the sixth to write.(表语)你将是第六个写的。

如:five dozen (of) eggs   五打鸡蛋
        hree hundred people  三百个人
