Not only did we lose all our money,but also came close to losing our lives,后面的losing为什么?

Not only did we lose all our money,but also came close to losing our lives,后面的losing为什么?

come close to doing sth 这里面的to是介词,所以后面要加动词ing形式 意思是接近/有机会/差点做某事

因为close to 这个词组里面的to不是动词不定式的to，而是一个介词to 后面要接一个名词。比如，靠近我： close to me！

be close to sth
