    You are what you eat. So maybe it’s time you started eating sensibly. Experts at the first Chinese Students Nutrition and Health Festival in Kunming last week singled out (挑选) several bad eating habits.
    Watching television while having meals or snacks.
    Doing this means you don’t pay attention to your food, forget how full you are and so overeat. It can also cause digestion(消化) diseases. One way to avoid this is only to eat in certain areas of your home.
    .  Replacing meals with snacks.
    Many students think that eating small snacks can help them diet. But it often results
    In overeating and health problems related to a lack of vegetables,carbohydrates, proteins and vitamins. Snaking only works if it is well planned and includes healthy foods such as nuts, vegetables, fruit and yogurt.
    .Having drinks rather than water.
    Fizzy(有气泡的)drinks and fruit juice are usually high in calories and sugar, which can cause weight problems. Water is important in making your brain cells and every organ in your body work properly. For your body to burn fat,it needs at least eight glasses of pure water a day. Liquids like soda(苏打水)and coffee actually take water away from your body.
    .Choosing meat and certain vegetables over others.
    Different foods provide different kinds of nutrition. If you don't have a balanced diet,
    this can result in malnutrition(营养失调)and a weaker body.
    .Eating throat tablets(润喉片)as if they were sweets.
    If you eat throat tablets when you have no throat disease, they may affect the bacteria
    (细菌)in your mouth and cause real throat problems.

    • 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
