The idea of Trump and U.S. government purchasing Greenland is ridiculous.
这句话中of和purchasing之间为什么可以添加名词短语The Trump and U.S. government呢?我们常用的表达不是直接为The idea of doing sth吗?麻烦详细解释一下! 谢谢!
划线部分是purchasing的逻辑主语
如 I am afraid of Tom/Tom's/him/his being found by the enemy.
比较: I am afraid of being found by the enemy. 则成了“I”被发现
