(E) Holland spends a larger percentage of its gross national product on defending its coasts from rising seas than the United States does on military defense.
这里defend sth. from rising seas是什么用法？是defend sth. from doing sth.还是rising seas是一个名词短语，rising修饰seas呢？那就是defend sth. from sth.？
那位NN能不能讲讲defend的用法，以及它和名词形式defense有什么区别呢？
谢谢！ |
