    When Percy Spencer invented the microwave, it changed the world greatly. People would no longer have to wait endless hours while cooking their food in an old-fashioned oven. Instead, using the microwave has allowed them to cook food in just seconds.
    According to the medical website mercola.com, just about “ninety percent of Americans have microwaves in their homes”. However, is this convenient invention as perfect as it seems?
    There are many reports of microwaves changing the original qualities of the food, which can cause cancer as well as changes in the body.
    “Electro-magnetic (电磁的) radiation harms food, and changes substances cooked in it to dangerous products,” Dr. Lita Lee – chemist, nutritionist, author and lecturer – wrote in her book, Health Effects of Microwave Radiation – Microwave Ovens (1991).
    However, the microwave is not only for food; microwaves are used in medicine as well. For example, it warms heating pads and used to warm blood used in transfusions (输血).
    Norma Levitt, a hip surgery patient in an Oklahoma hospital (1991), died after blood being heated for her transfusion was altered in the microwave. A lawsuit followed and because of this incident, blood is no longer heated in the microwave.
    Regardless of what has happened, big companies still claim that microwaves are great machines that have caused trouble to “few people” and have had “few consequences”. However, people should decide if saving a few minutes is more important than preventing cancerous cells from entering the body.
    Dr. Jonathan Wright, Medical Director of Tahoma Clinic in Renton, Washington, considers the microwave unhealthy and recommends some alternatives.
    “Try eating a lot of your food, like vegetables, uncooked. Ideally, at least one-third of the food in your diet should be uncooked, since this is the form that will give you the maximum amount of nutrients. If you do want to cook some food or heat up leftovers, use your stove (火炉),” he said.
    These alternative cooking styles may take a little time from your day, but can help you lead a healthier and more stable lifestyle. These methods will allow you to get the most nutrients from your food, as well.
    Health is not valued till sickness comes. In today’s fast-paced modern world, we should have more consideration towards peoples’ health.

    • 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
