    What is eco-fashion? Eco-fashion is a complex phenomenon and the common use of the term covers two aspects of fashion——'ecological ' and 'ethical ' (伦理的). Ecological fashion usually refers to textile(织物) and clothing production processes and the environmental issues surrounding them; ethical fashion generally relates to the working conditions involved in the producing processes.
    What are the problems with fashion? Firstly, the production of textiles pollutes the environment heavily. Cotton-planting uses pesticides; sheep-farming and wool-cleaning contribute to global warming; synthetics-making (人造纤维生产) brings about harmful waste. Secondly, every stage of clothing production has a significant effect on the environment. They all use a great deal of energy, and some also involve harmful chemicals. In addition to this, there is a lot of waste produced in the process, especially in the form of polluted water. Thirdly, growing consumption levels and our shopping habits further worsen the bad effects. We are now buying clothes in increasing quantities without realizing the scale on which it affects natural environment, and we are also quick to throw away clothes that have been worn only a couple of times.
    Then, how to solve the problem? To a large degree, it is the fashion producers that really have the power and the responsibility to shape our future. There are numerous ways in which these producers can reduce their ecological footprint, from switching to green energy and reducing energy use, through selecting sustainable(可持续使用的) materials and choosing local suppliers, to recycle and minimize waste. On the other hand, as consumers we can all make contributions by selecting environmentally friendly clothing and reducing clothing consumption.
    Now many people are beginning to shop for organic food products because the benefits of eating food free of chemicals are straightforward and immediate. They relate directly to our personal health. In fact, choosing eco-fashion can also contribute to our personal health, though it is mostly done by way of keeping the health of the planet.

    • 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
