to 有两种用法,一是当不定式用,后面跟动词原型,如:
continue to do sth.
agree to do sth.
to 还可以当介词用,后面跟名词性词组,如:
give the book to me
respond to the issue
那么当介词的时候,如果后面要跟动作,就要用动名词.'动名词'就是动词当名词用,形式为动词+ing.只要to是介词,后面跟的动词就要动名词形式,不分哪些词,如:
look forward to doing sth.这里的to是介词,后面要加doing,如:
I look forward to meeting you.(meeting you是动名词词组)
I look forward to the meeting.(the meeting是名词词组)
清楚了吗?
