什么时候to当做介词用？
作者&投稿：度可 （若有异议请与网页底部的电邮联系）
在动词原形前的to是动词不定式，这时也叫小品词。其它情况是介词。
to 除了在动词不定式前以外，一般来说，
都作介词用。如：
listen to
pay attention to
look forward to
...
be strange (common, new, familiar, peculiar, distinct, sensitive, immune, vulnerable, indispensable) to
Air is indispensable to life.
Aircrafts are vulnerable to interference caused by radiation.
This injection will make you immune to infection.
