问题 As early as 1647 Ohio made a decision that free, tax-supported schools must be established in every town______50 households or more.
选项 A、having
B、to have
C、to have had
D、having had
答案A
解析 本题考查非谓语动词的用法。句意：早在1647年俄亥俄州就做出决定，拥有50或50户以上家庭的每一个镇，都必须建立免费的由税收维持的学校。根据题干可知，“拥有50或50户以上家庭”是一个含有动词的短语，修饰限定“城镇”，这时需要把“拥有”这个动词变为非谓语形式。从形式上看，四个选项都没有问题，但to do sth．作后置定语时表示将要发生的动作，与题意不符，所以排除选项B和选项C。“拥有50或50户以上的家庭”只是对当时事实情况的一种描述，所以应该用一般性时态，选项D为现在完成时态，应排除。故本题选A。
