【语篇解读】　本文是一篇说明文。介绍了食物沙漠的概念。

1．without　[考查介词。根据语境可知，此处指没有交通工具便很难到达杂货店，故填without。]

2．becomes/will become　[考查时态和主谓一致。本文的基本时态为一般现在时，此处也应用一般现在时；又动词的­ing形式作主语，谓语动词使用单数。此外，这里也可理解为将来的一种情况，从句用一般现在时表将来，主句用一般将来时。]

3．an　[考查冠词。过去十年里，美国人平均开6英里的车程以往返于家和最近的杂货店。an average of"平均"。]

4．especially　[考查副词。此处指特别是住在南方的美国乡下人，especially"特别，尤其"。]

5．longer　[考查形容词比较级。根据上下文语境及空前的"much"可知，此处指美国乡下人，特别是住在南方的美国乡下人去购物的旅途更远，故使用比较级。]

6．serving　[考查动词的­ing形式。分析句子结构可知，find为谓语动词，one supermarket与serve之间是逻辑上的主谓关系，故此处应用动词的­ing形式作后置定语。]

7．to drive　[考查动词不定式。动词expect后接不定式作宾语。expect to do sth."
