解析

【分析】
这道题要求用方框内单词的适当形式填空,需结合每个空的句子结构、语境,以及单词的词性变化来解题。首先通读短文,明确是围绕保持健康的饮食建议展开,再逐个分析每个空:1空修饰名词food需形容词,2空修饰名词health需形容词性物主代词,3空对应前文的First用序数词,4空与breakfast、lunch并列需三餐类名词,5空修饰名词activities需形容词,最后匹配方框内单词转换形式填空。
【解析】
1. 空后是名词food,需形容词作定语,方框中名词health的形容词形式为healthy,符合“不同种类的健康食物”的语境;
2. 空后是名词health,需形容词性物主代词作定语,方框中主格代词we的形容词性物主代词是our,意为“对我们的健康有益”;
3. 前文用First(第一)列举建议,此处是第二点,需用序数词,方框中second首字母大写为Second;
4. 前文提到breakfast(早餐)、lunch(午餐),三餐对应方框中的dinner(晚餐);
5. 空后是名词activities,需形容词作定语,方框中名词day的形容词形式为daily,意为“日常活动”。
