    President Barack Obama shouldn’t be surprised if his approval rating among students has plummeted( 陡然变差 ). In a recent speech about US education, he called for extending the school day and year. "The challenges of a new century demand more time in the classroom. Why more time? Because US students are falling behind students in other countries," he said.
    More school
    US schools need to lengthen school days and the school year. If we intend to stay competitive with the rest of the world on test scores and in the job market, we need to add classroom hours and get rid of summer break almost entirely. As President Obama said. South Korean students spend mere than a month longer in school — and achieve better results than us.
    The current two-term school year and the school days that form it were developed based on an old system of agriculture. The long summer break allowed children to be home to help tend the fields. It is not necessary anymore. It may not be popular to cut summer break or extend school days, but that’s the only way to improve US education and get back the American jobs lost to foreign countries.
    Home Time
    Adding school hours won’t solve the problems with our school system. The USA is different from other countries. US families have full schedules, with participation in sports, community groups, and other interests. In places such as South Korea, where only several hours of a day aren't spent on school work, children don t have time to participate in many of those activities.
    Giving kids time outside of school allows them to grow in other areas. That’s just as important as learning fractions (分数). Fingers shouldn't be pointed at the school year for being too short, but at teachers and schools that don't challenge their students and just pass kids along to the next grade. We do need to hold ourselves accountable for an education system falling behind other countries, but we also need a solution that actually works.

  • 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
