    ﹝1﹞The number of children younger than 12 entering the hospital for eating disorders increased 119 percent between 1999 and 2006, according to a new report suggesting eating disorders for this age group are on the rise. 
    ﹝2﹞The new report summarizes data from 200 recent research studies that examined eating disorders. It is published by the American Academy of Pediatrics and suggests that pediatricians screen for eating disorders as part of annual checkups or during pre-participation sports exams.
    ﹝3﹞Since eating disorders will impact a child’s entire health, the report recommends that pediatricians should monitor patients for medical or nutritional problems, and ensure patients receive appropriate treatment such as medical care, mental-health treatment and nutritional intervention.
    ﹝4﹞"Pediatricians are encouraged to advocate for legislation and policies that ensure appropriate services for _________________, including medical care, nutritional intervention, mental-health treatment and care co-ordination," conclude report author Dr. David Rosen of the University of Michigan and his coauthors.
    ﹝5﹞There is also an increasing recognition of eating disorders in males, which now represent up to 10 percent of all cases of eating disorders, as well as in children of younger ages.
    ﹝6﹞While gender, body type, and weight can be indicators of an eating disorder, it is becoming more common for both boys and overweight children to succumb to an eating disorder. Therefore, when evaluating patients, the report urges that pediatricians should not only track weight and height, but body mass index (BMI), too. In girls, the report urges doctors to track menstrual cycles, and to be specific about questioning diet, eating patterns, and body image.
    ﹝7﹞People with eating disorders often use their control over food in an attempt to compensate for overwhelming feelings and emotions. Eating disorders are also often tied into a person's own body image and have been previously linked to higher rates of self-harm.
    ﹝8﹞Eating disorders are treated most commonly through psychotherapy, and a full recovery is possible for most people who experience an eating disorder.
    小题1:What is the main idea of the text? (no more than 8 words)
    小题2:Fill in the blanks with proper words in paragraph 4.
    小题3:Why do people with eating disorder use their control over food?
    小题4:What factors are important to evaluate a girl who is suffering eating disorder?
    小题5:Translate the underlined the sentence in paragraph 3.

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

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。

        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
