像不定式，动名词和分词这三类非谓语都可以放在句首呀。如：To go to school early the next day, he went to bed. Rising up early every morning is a good habit. Protected by the parents very well, the little girl seemed a bit shy.作定语的非谓语？不定式，动名词和分词也都可以作定语。如：I have something to do。 (不定式作定语) living fish (动名词作定语) an educated man (分词作定语)
