I'll try to find out if the machine is in good condition.为什么可以用if?
介词后要用whether表是否,为什么这句话中可以用if?

...out ...不是介词,是副词.
再问：怎么区别是介词还是副词呢?
再答：一言难尽。很多时候，一个小品词有时是介词有时是副词。主要看它在句子中的功能。如 on, The light is on. = burning/ working, 是副词：亮着的。 Avatar is on at the cinema. = shown 是副词，放映 The book is on the desk. 是介词，在……之上。原则上，adv. 是“实词”，自身有内容，可独立使用，后面不需再跟一个名词等其他成分的。而介词则是典型的“虚词”，自身无内容，它的特定词义取决于后面所修饰的名词。没有了后面的名词，介词就没有意义，或无法确定其词义。比如，我问：介词 on...是什么意思？你很难回答! 但放在语境中，就明确了，而且有不同的意义： a book on the desk: 在……之上 on 24 October 在某日 a book on English learning 关于……论述…… etc.
再问：很感激你的讲解!那请问What we can't get seems better than what we already have.为什么不能转化为it作形式主语呢?变成It seems what we can't get better than what we already have.谢谢!
