    Health researchers have noticed that some groups of people are more consistently healthy than others, and wondered… Is it race? Income? Where you live? In the United States, these disagreements in health outcomes have been the focus of intense research for the past several decades.
    Harvard University health policy researcher Ellen Meara says scholars have found some clues as to why some groups of people have more or less disease than others. She says one important factor in people’s health is the amount of education they have.
    In her most recent paper, Meara looked at data from the United States census. Meara and her colleagues examined data from several decades.
    “We looked at life expectancy(预测寿命)at age 25,” Meara says.
    “How many additional years can you expect to live if you arrive at age 25 and your education has stopped at high school, or sooner? Versus how many years, can you expect to live if you’ve reached aged 25 and you’ve gone on to at least some college…”
    Meara says they found that in 1990, a 25-year-old who only had some secondary school could expect to live for a total of 75 years. In 2000, a 25 year old with some secondary education could also expect to live to the age of 75.
    In contrast, for a better educated 25-year-old, they could expect to live to the age of 80 in 1990. Someone with a similar education level in the year 2000, could expect to live to be more than 81 years, 81.6 years to be exact .
    Meara says, not only do better-educated people live longer to begin with, but in the past ten years, more educated people has made gains in the length of their lives. Meanwhile, the life expectancy hasn’t changed for less educated people.
    Some of these gains can be explained. Meara says researchers know that people who are more educated are more likely to quit smoking cigarettes, or not start at all, compared to people with less education.
    “I think it’s a reminder not to be satisfactory,” Meara says. “Just because a population overall appears to be getting healthier, it doesn’t always mean that those advantages and successes that many people have enjoyed really extend into all parts of the population. And I think that's something to really pay attention to regardless of whether you live in the US or elsewhere.”
    Meara points out that education can often determine income - people with more education frequently make more money. This makes them aware of health care, and purchase other resources and services that can keep them healthier. But the data on income do NOT show that people who make more money are automatically healthier.

    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
