12．Something as simple as vegetables in childhood may help to protect you against serious illness in later life．（ ）| A． | to eat | B． | eating | C． | to be eating | D． | eaten |
分析 小时候像吃蔬菜这样简单的事情也许可以帮助你对抗晚年的严重疾病．
解答 答案：B
句中eat vegetables作介词as的宾语，表示比较对象，要用动名词形式；句意表达的是客观事实，不能用不定式来构成，不定式表达的是未发生的动作．故选B．
点评 动名词相当于名词，具备名词的特征．在句中可以作主语，宾语，表语，定语等．动名词和现在分词的构成方式一样，但用法不同．现在分词具备动词的特征，有时态和语态的变化，学习时要注意区分和掌握．
