It is much easier to get into debt than to get out of it.
语法解释是说:当连接两个非谓语动词时通常应使用一样的形式。 这里的不定式是目的状语吗?我怎么感觉这里的不定时其实是做主语啊,那这样的话,为什么说成非谓语动词呢?
It is much easier to get into debt than to get out of it.
你的理解是对的,这里的不定式不是什么目的状语,而是作主语的,相当于:
To get into debt is much easier than to get out of it.
你的疑问是:我怎么感觉这里的不定时其实是做主语啊,那这样的话,为什么说成非谓语动词呢?——你认为“非谓语动词不能作主语”,是吗?错了,其实,不定式和动名词这样的非谓语动词是可以用作主语的。又如:
To act like that is childish. 这样做是幼稚的。
To accept their offer would be foolish. 接受他们的帮助是愚蠢的。
To say is one thing, but to do is another. 说是一回事,做是另一回事。
To affect a policy is to have an effect on it. 影响一项政策就是对该政策具有一种影响。
To marry a woman for her beauty is like buying a house for its paint. 由于面貌美丽而娶妻,犹如油漆漂亮而买屋。
To boot (up) a computer is to load an operating system into the computer’s main memory. 引导计算机就是指将操作系统加载计算机主存储器。
